Scale of Patch Tuesday September 2026 

The Two Exploited Zero-Days 

Other Notable CVEs Worth Tracking 

• CVE-2026-55007 (CVSS 8.1) — a double-free flaw in Microsoft Exchange Server enabling remote code execution 

• CVE-2026-80097 (CVSS 8.6) — improper authentication in Microsoft Authenticator allowing local privilege escalation 

• CVE-2026-69465 (CVSS 8.8) — missing authorization in Microsoft Office SharePoint permitting remote code execution 

• CVE-2026-65669 (CVSS 9.6) — an injection flaw in SQL Server enabling remote privilege escalation 

• CVE-2026-69525 (CVSS 9.8) — use-after-free in Windows Remote Desktop Services allowing remote code execution 

• CVE-2026-69595 (CVSS 9.8) — use-after-free in the Windows Services for NFS ONCRPC XDR Driver 

• CVE-2026-69730 (CVSS 9.8) — use-after-free in the Windows DNS server 

• CVE-2026-69829 (CVSS 9.8) — heap-based buffer overflow in Windows Shell 

• CVE-2026-72979 (CVSS 9.8) — use-after-free in the Windows DHCP Server 

Microsoft’s September 2026 Patch Tuesday addresses 964 CVEs, including 104 rated Critical and 860 rated Important, making it the company’s largest Patch Tuesday release on record.

Microsoft lists 974 CVEs in its full September security release. However, 10 of those affect cloud services or involve fixes that Microsoft applies itself, leaving 964 vulnerabilities that customers need to patch.

The release includes fixes for two actively exploited Windows zero-days. Both are local elevation-of-privilege vulnerabilities that could allow an attacker who already has access to a device to gain SYSTEM privileges. Neither provides remote access by itself, but SYSTEM-level access is valuable to malware operators after they gain an initial foothold through phishing, stolen credentials, or another method.

How to apply patches and check if you’re protected

These updates fix security problems and help keep your Windows PC protected. Here’s how to make sure you’re up to date:

• Click the Start button, then open Settings.
• Select Windows Update (usually at the bottom of the menu on the left).
• Click Check for updates. Windows will search for the latest security updates. If you’ve enabled Get the latest updates as soon as they’re available under More options, you may be prompted to restart immediately to complete the update. Otherwise, continue to the next step.

• If updates are available, they’ll start downloading automatically. When they’re ready, click Install or Restart now if prompted. Your computer may need a restart to finish the update.
• After restarting, go back to Windows Update and check again. If it says You’re up to date, you’re all set.
  

Technical details

The unusually large batch also includes high-severity remote-code-execution vulnerabilities in Windows DNS Server and Remote Desktop Services, as well as fixes affecting Exchange Server, SharePoint, SQL Server, Office, and core Windows components.

Let’s take a closer look at the two zero-day vulnerabilities. Microsoft classifies a vulnerability as a zero-day if it was publicly disclosed or actively exploited before an official fix became available.

The first is a Windows Update Stack elevation-of-privilege (EoP) vulnerability with a CVSS score of 7.8 out of 10, tracked as CVE-2026-81963. The description says:

“Improper link resolution before file access (‘link following’) in Windows Update Stack allows an authorized attacker to elevate privileges locally.”

This means Windows can be persuaded to open or modify the wrong file because it follows a shortcut-like pointer without properly checking where that pointer leads. Microsoft says attackers exploited the bug before a patch was available.

The second zero-day, tracked as CVE-2026-85880, also has a CVSS score of 7.8 out of 10. Microsoft describes it as:

“heap-based buffer overflow in Windows ALPC allows an authorized attacker to elevate privileges locally.”

Microsoft says an attacker who can execute code in a low-privilege AppContainer could exploit the vulnerability locally to escape the sandbox and elevate their privileges on the affected system. No additional user interaction is required.

Windows ALPC is an internal messaging system in the Windows operating system that allows different programs on the same computer to communicate with each other quickly.

A buffer overflow occurs when an area of memory within a software application reaches its boundary and data spills into an adjacent memory region. The heap is a region of memory used for dynamic memory allocation.

These are not the kinds of bugs a typical victim triggers merely by opening a malicious document or visiting a website. But local privilege escalation is a critical part of many attack chains: After malware runs with limited rights, a SYSTEM-level exploit can help an intruder disable defenses, access protected data, establish persistence, or move through a network.

Microsoft Corp. today issued updates to plug at least 974 security holes in its Windows operating systems and other software, by far its biggest single patch batch ever. Microsoft says artificial intelligence is helping to speed the discovery of vulnerabilities, but security experts warn that many organizations already are struggling to prioritize the more human-intensive endeavor of testing and deploying so many fixes each month.

This month’s patch bundle obliterates the software giant’s previous record set in July, when it released updates for at least 570 security vulnerabilities. September’s Patch Tuesday brings this year’s total to more than 2,600, more than twice Microsoft’s previous record-setting patch year in 2020 (1,245) and with three more months to go.

There are two “zero-day” flaws fixed this month that are being actively exploited: both CVE-2026-81963 and CVE-2026-85880 allow an attacker to elevate their privileges on Windows system.

Fully 113 of the bugs addressed today earned Microsoft’s “critical” rating, meaning they could be abused by malware or miscreants to seize control over a vulnerable Windows machine with little or no help from the user.

Among the more serious critical flaws this month is CVE-2026-69730, a DNS weakness present in Windows Server 2012 onward and on Windows 10. Microsoft warns that an unauthenticated attacker could leverage this weakness simply by sending a specially crafted packet to an affected system, and that it is likely to be exploited.

Also scary is CVE-2026-69829, a critical, remote code execution flaw in the Windows Shell. This vulnerability has a CVSS base score of 9.8 (10 is the most severe), and can be exploited with low attack complexity, no privileges, and no user interaction.

Microsoft is hardly alone in shipping monster patch bundles lately. Many other large software companies, including Adobe, Cisco, Google, Mozilla and Oracle, all have recently credited AI-assisted research with increasing their patch cadence and volume (Google said today it is now going to ship security updates every two weeks).

Tyler Reguly, associate director of security research and development at Fortra, said one core challenge with deploying Windows updates is that they need to be tested before being installed across an organization because not all third-party software works seamlessly in the face of changes to the underlying operating system.

“It’s time to put our CISOs and CSOs on notice,” Reguly said. “How are you helping your teams through these difficult times? Do you have your teams deploy after hours and on weekends to avoid disruption to the business environment? Do you reward them for that effort? Time to dig into your budget and buy dinner for your teams that are working on Saturday to get patches rolled out before users return to work on Monday.”

Satnam Narang is senior staff research engineer at Tenable. Narang said it’s important to recognize that while the number of vulnerabilities being patched by Microsoft is rising, the number of flaws that can and will affect most organizations remains quite low.

“AI-assisted vulnerability discovery in 2026 is creating larger haystacks, but it isn’t finding more needles,” he said. “It’s critical that organizations understand which vulnerabilities actually apply to them, whether they pose a threat by being reachable and exploitable, and prioritize remediation based on this risk context.”

Of course, regular Windows users don’t need to test patches before deploying them, but they still need to open Windows Update periodically or else assent to the program’s nag notices about pending updates. And at the rate these Windows patch releases are ballooning in size, it’s probably best not to let them pile up month after month.

Enterprise Windows admins will want to keep an eye on askwoody.com for news of any updates that appear to be causing problems. As always, the SANS Internet Storm Center has a per-patch breakdown ordered by severity and urgency.

SonicWall disclosed this week that attackers are chaining two previously unknown vulnerabilities in its SMA1000 secure access appliances to run commands on unpatched devices, and urged customers to install an emergency hotfix.

The more severe flaw, CVE-2026-83548, is a pre-authentication server-side request forgery weakness in the appliance's Appliance Work Place interface, rated 10.0 on the CVSS scale. It lets a remote attacker with no credentials reach sensitive internal functionality. The second, CVE-2026-83549, is an operating-system command injection bug in the Appliance Management Console rated 7.8; on its own it requires administrative authentication, but paired with the SSRF flaw it yields remote code execution.

The vendor said it found both issues internally and then observed them being used together in live attacks. SonicWall has not published indicators of compromise or described the attackers.

Affected products are the SMA1000 series 6210, 7210 and 8200v, in both hardware and virtual form. Fixed builds are 12.4.3-03526 and later, and 12.5.0-02952 and later. SonicWall firewalls running SSL-VPN and the separate SMA 100 line are not affected.

Remediation guidance goes beyond patching. SonicWall told customers to contact its support organization to review appliances for signs of intrusion and, where compromise is suspected, to re-image or redeploy the device, rotate all credentials and reset TOTP tokens — an acknowledgment that one-time-password seeds stored on a breached appliance survive a software update. The company said customers should move to the hotfix release as quickly as possible.

Shadowserver Foundation scanning has tracked more than 400 internet-exposed SMA1000 appliances, though an unknown share of those are already patched. The small install base belies the risk profile. These are remote-access gateways that sit at the network edge and hold credentials for the environments behind them.

The disclosure extends a difficult run for the product line. Attackers exploited a separate pair of SMA1000 zero-days in July 2026, tracked as CVE-2026-15409 and CVE-2026-15410, to deploy custom malware; CISA later confirmed ransomware operators were abusing that access.

Read: CISA Adds SonicWall SMA1000 Vulnerabilities to KEV Catalog Following Active Exploitation

Another zero-day surfaced in December 2025. Seventeen SonicWall vulnerabilities across the company's product families currently sit in CISA's Known Exploited Vulnerabilities catalog. Edge appliances from SonicWall, Ivanti, Citrix and Fortinet have collectively become the preferred initial-access route for ransomware affiliates and espionage crews, because they are internet-facing by design and rarely instrumented with endpoint detection.

Chrome is rolling out an update for its desktop browser. The update includes 26 security fixes, two of which Google rates as critical use-after-free vulnerabilities.

How to update Chrome

If you don’t want to wait for the rollout to reach you, manually updating is easy.

The easiest option is to allow Chrome to update automatically. But you can end up lagging behind if you never close your browser or if something goes wrong with the update.

To update manually, click the More menu (three dots), then go to Settings > About Chrome. If an update is available, Chrome will start downloading it automatically. Restart Chrome to complete the update, and you’ll be protected against these vulnerabilities.

You can find an explanation of the version numbering system and step-by-step instructions in our guide: How to update Chrome on every operating system.

Technical details

Let’s look at the two critical vulnerabilities. Both are use-after-free (UAF) vulnerabilities. A use-after-free vulnerability occurs when a program attempts to access a memory location after it has been freed. That can cause crashes or, in some cases, allow an attacker to run their own code.

The first, tracked as CVE-2026-84353, was found in Shared Tab Groups and could allow a remote attacker using social engineering to execute arbitrary code outside the browser sandbox via a crafted HTML page. Here, social engineering likely means an attacker would have to lure you to a malicious website or open an email in HTML format.

The other critical vulnerability, tracked as CVE-2026-84352, was found in WebGL. WebGL, short for Web Graphics Library, is a browser technology that lets websites display interactive 2D and 3D graphics. The vulnerability could allow a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page.

Chrome vulnerabilities that enable remote code execution outside the browser sandbox are particularly valuable to attackers because they can turn a visit to a malicious or compromised website into direct code running on the underlying operating system, often without requiring additional exploitation steps.

Microsoft’s August 2026 Patch Tuesday addresses 421 Microsoft vulnerabilities, including 62 rated Critical. One Windows vulnerability has been exploited in the wild by the Lazarus group to gain SYSTEM privileges.

The August update is smaller than July’s record-breaking release, but it’s still among Microsoft’s largest Patch Tuesday batches. More importantly, it includes several flaws likely to attract attacker interest: a publicly disclosed Windows privilege escalation flaw with a proof-of-concept (PoC), a newly completed unauthenticated SharePoint remote code execution (RCE) chain, and a potentially wormable Windows DNS Server flaw.

How to apply patches and check if you’re protected

These updates fix security problems and help keep your Windows PC protected. Here’s how to make sure you’re up to date:

• Click the Start button, then open Settings.
• Select Windows Update (usually at the bottom of the menu on the left).
• Click Check for updates. Windows will search for the latest security updates. If you’ve enabled Get the latest updates as soon as they’re available under More options, you may be prompted to restart immediately to complete the update. Otherwise, continue to the next step.

• If updates are available, they’ll start downloading automatically. When they’re ready, click Install or Restart now if prompted. Your computer may need a restart to finish the update.
• After restarting, go back to Windows Update and check again. If it says You’re up to date, you’re all set.

Technical details

Windows Deployment Services (WDS) users should prioritize CVE-2026-62893 (CVSS score 9.8 out of 10), an unauthenticated RCE flaw in the TFTP (Trivial File Transfer Protocol) server. TFTP normally runs on UDP port 69 and has no built-in authentication. It is primarily an enterprise and school network issue, but it could enable lateral movement where WDS is deployed.

Microsoft also fixed CVE-2026-62832, a publicly disclosed elevation of privilege (EoP) vulnerability in the Windows User Profile Service. It maps to the issue researchers called LegacyHive, for which a limited public proof of concept was released in July.

The PoC demonstrates how a local authenticated attacker could abuse the service’s registry hive handling to load another user’s hive, potentially including an administrator’s. The released demonstration is deliberately constrained and requires credentials for another user, but the availability of code and the broad Windows footprint make this one a strong candidate for exploitation attempts.

Another good reason to promptly update is the number (I counted 48) of remote code execution (RCE) fixes for Office applications and components, including Excel, Word, Outlook, PowerPoint, and the Office graphics component. Document-borne vulnerabilities are attractive to phishing operators because email attachments and shared documents provide delivery mechanisms that people are likely to open.

Microsoft today released updates to remedy at least 398 security vulnerabilities in its Windows operating systems and supported software, including one weakness that is already being actively exploited and two others that were publicly detailed prior to today.

Image: Shutterstock, Mallika Home Studio.

August’s overstuffed bundle of patch joy from Microsoft did not eclipse its recording breaking release of more than 570 security updates last month, but it is double June’s then-record batch of nearly 200 fixes. Microsoft has attributed the recent patch deluge to vulnerability discoveries aided by artificial intelligence, and experts roundly agree that Windows users should get used to the idea of Patch Tuesdays (the second Tuesday of each month) covering hundreds of newly discovered security flaws.

Fully 42 of the 398 flaws that Microsoft patched today earned Redmond’s most-dire “critical” rating, meaning they are severe enough that malware or malcontents could exploit them to gain remote control over a Windows computer with little to no help from the user.

The sole known “zero day” bug fixed by Microsoft this month is CVE-2026-68820, a privilege escalation weakness in a core Windows component called afd.sys, which the security firm Automox describes as “the driver behind Windows socket connections on effectively every endpoint.”

“This isn’t a front-door bug,” Automox’s Landon Miles wrote in a Patch Tuesday blog post. “It’s step two in a chain: an attacker phishes their way into a low-privilege foothold, then uses the driver flaw to take the box. The 7.0 score reflects the high attack complexity, because race conditions are fiddly. The exploit has to be thrown over and over until the timing lands. Someone is clearly landing it anyway.”

CVE-2026-62832 is another privilege escalation flaw that Microsoft has labeled likely to be exploited; this flaw, in the Windows User Profile Service, may be related to the recent “LegacyHive” public disclosure from the prolific bug hunter known as Nightmare Eclipse. The other publicly disclosed flaw is CVE-2026-72971, a low-impact local tampering vulnerability that Microsoft reckons is unlikely to be exploited.

Other major software makers are likewise increasing their patch volumes and cadence thanks to AI, including Adobe which last month moved to twice-monthly security bulletins published on the 2nd and 4th Tuesday of each month. Cisco, Google, Mozilla and Oracle also are shipping updates far more frequently and abundantly.

By all accounts, AI is quite good at finding security holes in software. But for now at least, patching the resulting bugpocalypse remains a heavily human-centric endeavor, and the jury is still out on whether AI technologies will turn out to be as good at fixing vulnerabilities as they are at finding and exploiting them. This is an important question when one considers that these same AI technologies also are suggesting fixes for the vulnerabilities they find.

Researchers at 1Password recently examined what happens when different large language models (LLMs) generate vulnerability patches for newly disclosed, complex vulnerabilities. They found the LLMs produced patches that failed to fix the flaw or added a new weakness in the process (or both) more than half the time.

Ed Skoudis, president of the SANS Technology Institute, said his team has seen excellent results using AI to generate patches, provided there are humans in the loop to test the suggested fixes and push for iterative improvements.

“AI is rapidly becoming astonishingly good at finding vulnerabilities, but this research shows that fixing them is a very different problem,” Skoudis wrote in a SANS newsletter today. “Don’t expect one-shot AI patching to work reliably. Instead, iterate, test, challenge, improve, and verify. AI can be an extraordinary patching partner, but today it still needs a skilled human at the keyboard.”

Tyler Reguly at Fortra says while reports of Microsoft patching hundreds of vulnerabilities in one go have prompted some organizations to try to patch faster, it’s important to bear in mind that only one of the almost 400 bugs addressed today is known to be actively exploited. Reguly suggested security leaders check in with their teams to see how they’re handling the increasing workloads, which often involve testing fixes before deploying them in production environments.

“If you’re a chief security officer talk to your teams about how they are shifting or modifying their workflows to better accommodate the patching shift that we’re seeing and support them across various organizational units by enabling the changes they want to see made,” Reguly said. “There’s no need to rush these updates, no matter what various vendors and organizations try to tell you. You need to make sure that you are rolling out safe updates that will not negatively impact your systems.”

Speaking of the humans behind the keyboards, don’t neglect to backup your system and/or data before applying this month’s monster patch load. The day after each month’s Patch Tuesday is sometimes derisively referred to as Reboot Wednesday, but it generally doesn’t hurt to wait a few days to apply these huge update bundles because it sometimes takes a couple of days for the occasional misbehaving patch to get ironed out properly by Microsoft.

Strip away the geopolitics, the hacktivist noise, and the espionage headlines, and one number from the first half of 2026 stands out above everything else: 1,721. That's how many ransomware attacks hit organizations in the United States between January and June, according to new research from Cyble Research and Intelligence Labs (CRIL). It's not just the highest total of any country tracked in the report — it's more than the next nine most-targeted countries combined.

Canada, in second place worldwide, recorded 179 attacks. Germany logged 155. The United Kingdom, 138. Add up the rest of the global top 10 — France, Italy, Spain, Thailand, India and Brazil — and the total still falls more than 600 attacks short of the U.S. figure alone. Out of 3,836 ransomware attacks CRIL tracked worldwide this half, roughly 45% landed on American soil.

A Single Region, an Outsized Share

Widen the lens slightly and the picture holds. North America as a whole recorded 1,981 ransomware attacks in H1 2026 — more than half of every ransomware incident Cyble observed globally — alongside 35 data breach and leak incidents and 9 initial access sale listings. The report describes the region as home to "a mature, persistently active RaaS ecosystem operating at high volume across a wide range of industries and geographies."

Two ransomware-as-a-service operators did much of the damage. Qilin, the single most prolific gang worldwide, claimed 370 of those North American attacks on its own — nearly 19% of the regional total. Akira followed with 268, and INC Ransom added another 164. Together, Qilin and Akira alone accounted for more than half of all recorded ransomware activity across the region, a level of concentration that points to a small number of highly organized affiliate networks doing the bulk of the damage rather than a diffuse swarm of opportunists.

Where the Pressure Lands

Professional Services bore the brunt of North American ransomware activity, with INC Ransom showing a marked preference for law firms and other high-value services with sensitive client data. Construction, Manufacturing and Healthcare followed close behind.

One operator, AiLock, stood out for a coordinated wave of victim disclosures that all landed on the same day — March 3 — a pattern consistent with a mass-exploitation campaign rather than isolated intrusions. LockBit, despite years of law enforcement pressure and takedown attempts, kept up a steady tempo against public-sector and educational targets throughout the period, showcasing how difficult the group has been to fully dismantle.

On the data breach side, Technology and financial services (BFSI) were the most frequently targeted sectors in North America, together accounting for roughly 43% of incidents — a reflection of how much intellectual property and monetizable personal data those industries hold.

Notably, Agriculture & Livestock emerged as a significant target for initial access brokers, accounting for a third of all access listings tied to the region. Cyble flags this as a sign of "growing risk in the food supply chain," an area that has historically drawn less attention from ransomware operators than finance or healthcare.

The initial access market itself was strikingly concentrated: two sellers, tracked under the handles "redpin" and "xpl0itrs," accounted for nearly all listings targeting North American organizations. Threat actors also continued to lean on known and zero-day vulnerabilities in widely deployed enterprise platforms — including products from Ivanti and Palo Alto Networks — as their preferred way into corporate networks.

Hacktivism Blurs into Cybercrime

North America wasn't spared the hacktivism wave sweeping the rest of the world either. Collectives including SOLDADOS DIGITALES – UNIÓN AMERICANA and LYSTIC TEAM #ID drove roughly 56 data leak or dump posts and touched about 360 unique domains across the region, with Government, Technology, financial services and telecommunications entities most frequently in the crosshairs.

Cyble's broader findings suggest many groups marketing themselves as ideologically driven hacktivists are, in practice, running side businesses in stolen data brokerage and DDoS-for-hire services — a blurring of motive that complicates how defenders triage the threat.

The scale of the U.S. numbers doesn't necessarily mean American companies have weaker defenses than their global peers — the concentration also reflects the sheer size and digital density of the U.S. economy, and its outsized share of the high-value targets ransomware affiliates chase. But the data does argue for a shift in posture.

Cyble's broader recommendations — treating data exfiltration, not just encryption, as the primary risk; prioritizing patches for the recurring vendor list; and monitoring initial access markets as a leading indicator rather than an afterthought — apply nowhere more urgently than in a country absorbing this much of the world's ransomware volume on its own.

The U.S. Department of Justice has seized more than 1,000 illegal World Cup streaming domains accused of broadcasting FIFA World Cup 2026 matches without authorization, marking a major enforcement action against digital piracy during the tournament. The domains were seized in three separate actions under U.S. copyright law as part of Operation Offsides, an initiative targeting websites involved in unauthorized World Cup broadcasts.

The latest action includes nearly 400 websites seized by the end of June, according to the Department of Justice. The investigation was carried out by U.S. Immigration and Customs Enforcement Homeland Security Investigations (HSI) Washington Field Office and the National Intellectual Property Rights Coordination Center.

Illegal World Cup Streaming Domains Targeted

According to an affidavit filed in support of a seizure warrant in the U.S. District Court for the Eastern District of Virginia, the seized domains were used to offer copyright-protected content through real-time streams of 2026 World Cup matches as they were being played and first broadcast.

HSI special agents confirmed that the domains were actively broadcasting World Cup matches without authorization. The domains were identified with assistance from FIFA, with additional information provided by beIN Media Group, NBC Universal, the Motion Picture Association’s Alliance for Creativity and Entertainment (ACE), Ultimate Fighting Championship (UFC), and Warner Brothers.

FIFA holds the exclusive rights to sanction and stage the FIFA World Cup 2026, which is being hosted across multiple cities in the United States, Canada and Mexico.

Operation Offsides Targets Illegal Streaming

The U.S. action is part of Operation Offsides, which focuses on identifying and seizing websites facilitating unauthorized broadcasts of World Cup matches.

The operation is led by the National Intellectual Property Rights Coordination Center and is being conducted with HSI Washington, D.C., HSI Attaché offices, private sector organizations and law enforcement partners globally.

Assistant Attorney General A. Tysen Duva of the Justice Department’s Criminal Division said the effort to seize more than 1,000 domains was aimed at protecting intellectual property rights and reducing risks to consumers from malicious software associated with some illicit streaming services.

HSI Deputy Executive Associate Director Matthew Millhollin also warned that users accessing unauthorized streaming platforms could face risks including malware and payment information theft.

Operation Red Card Expands Global Crackdown

The U.S. enforcement action was accompanied by international efforts under Operation Red Card, which targeted digital piracy and counterfeiting connected to the World Cup across the Western Hemisphere.

The Justice Department’s International Computer Hacking and Intellectual Property (ICHIP) program coordinated enforcement efforts involving Argentina, Brazil, Chile, Colombia, the Dominican Republic, Ecuador, Paraguay and Peru.

The coordinated actions resulted in hundreds of illegal streaming sites being blocked, including 14 in Argentina, 223 in Ecuador, 28 in Peru, 309 in Brazil, 256 in the Dominican Republic and 1,140 in Colombia.

Colombian authorities also conducted 13 nationwide search-and-seizure operations targeting counterfeit sports apparel, resulting in 11 arrests and convictions.

Cybercrime Group Arrested in Colombia

On July 10, authorities launched Phase II of Operation Red Card in Colombia, conducting simultaneous operations in Bogotá, Soacha, Maríalabaja, Manatí and Sincerín.

An ICHIP-mentored cybercrime prosecutorial team from the Colombian Attorney General’s Office arrested four members of the cybercriminal group Los Ciberinfiltrados. According to the Justice Department, the group had illegally accessed telecommunications systems since 2024 and sold pirated streaming content, including World Cup matches.

The group allegedly used fraudulent credentials, VPNs, interception of security codes and manipulation of corporate system profiles to distribute the pirated content.

In Europe, ICHIP Bucharest also coordinated with Europol and international counterparts to address illegal streaming activities during the World Cup.

World Cup Streaming Crackdown Intensifies

The latest action follows a June 2026 announcement by the U.S. Department of Justice involving the seizure of nearly 400 websites accused of illegally broadcasting FIFA World Cup 2026 matches.

That earlier enforcement action, also conducted under Operation Offsides, targeted websites accused of copyright infringement by offering unauthorized live streams of World Cup matches for profit.

With more than 1,000 domains now seized in the U.S. actions, authorities continue to target unauthorized streaming platforms and digital piracy networks linked to the tournament.

Just one month ago, June 2026 Patch Tuesday broke Microsoft’s previous record with 206 CVEs and three zero‑days. July now triples that count, reinforcing that the era of “small” Patch Tuesdays may be over as AI‑driven vulnerability discovery ramps up.

The update includes 59 critical vulnerabilities, as well as three publicly disclosed zero-days. Microsoft classifies these as zero-days because information about the vulnerabilities became public before patches were available. Two are known to be actively exploited by attackers.

How to apply patches and check if you’re protected

These updates fix security problems and keep your Windows PC protected. Here’s how to make sure you’re up to date:

1. Open Settings

• Click the Start button, then open Settings.

2. Go to Windows Update

• Select Windows Update (usually at the bottom of the menu on the left).

3. Check for updates

• Click Check for updates. Windows will search for the latest security updates.
• If you’ve enabled Get the latest updates as soon as they’re available under More options, you may be prompted to restart immediately. If so, restart your computer to complete the update. Otherwise, continue to the next step.
  

4. Download and install

• If updates are available, they’ll start downloading automatically. When they’re ready, click Install or Restart now if prompted. Your computer may need a restart to finish the update.

5. Double-check you’re up to date

• After restarting, go back to Windows Update and check again. If it says You’re up to date, you’re all set.

Technical details

Let’s look at the three zero-days.

First is a Windows BitLocker security feature bypass vulnerability, tracked as CVE-2026-50661. It is not known to be actively exploited. Microsoft describes it as:

“Protection mechanism failure in Windows BitLocker allows an unauthorized attacker to bypass a security feature with a physical attack.”

In other words, even if you’ve encrypted your machine with BitLocker, an attacker could exploit this vulnerability to access your data if they have physical access to your computer.

Next is the actively exploited CVE-2026-56155, an Active Directory Federation Services (ADFS) elevation of privilege (EoP) vulnerability. ADFS is a Microsoft software component that provides single sign-on (SSO) and federated access. It acts as a trust broker between an organization’s Active Directory and applications. An attacker who successfully exploited this vulnerability could gain administrator privileges. Reportedly, Microsoft discovered the vulnerability while investigating active attacks.

Last but not least is CVE-2026-56164, a Microsoft SharePoint Server elevation of privilege vulnerability. SharePoint Server is the on-premises version of Microsoft’s web-based collaboration and document management platform. A missing authentication check in Microsoft Office SharePoint could allow an attacker to elevate privileges over a network.

Both actively exploited vulnerabilities have been added to the Cybersecurity and Infrastructure Security Agency (CISA) Known Exploited Vulnerabilities (KEV) Catalog, which sets patch deadlines for Federal Civilian Executive Branch (FCEB) agencies. CISA has also urged organizations using SharePoint Server to implement hardening measures after the latest exploitations.
