IT threat evolution in Q2 2026. Non-mobile statistics

The mobile section of the quarterly cyberthreat report includes statistics on malware, adware, and potentially unwanted software for Android, as well as descriptions of the most notable threats for Android and iOS discovered during the reporting period. These statistics are based on detection alerts from Kaspersky products, collected from users who consented to provide statistical data to Kaspersky Security Network.

The quarter in figures

According to Kaspersky Security Network, in Q2 2026:

• More than 1.99 million attacks on mobile devices utilizing malware, adware, or unwanted mobile software were blocked.

• The Trojan-Banker category was the most prevalent mobile malware threat with a 30.77% share of total detected applications.
• More than 304,000 malicious installation packages were discovered, including:
  • 93,574 packages were related to mobile banking Trojans;
  • 570 packages were related to mobile ransomware Trojans.

Quarterly highlights

Attacks on mobile devices involving malware, adware, or unwanted software continued their downward trend, falling to 1,996,823 in Q2 from 2,676,328 the previous quarter.

We noted a downward trend in attacks driven by specific strains of pre-installed Trojans — a shift likely tied to the rollout of patched vendor firmware.

In Q2, our telemetry uncovered multiple malicious loaders hosted directly on Google Play. As highlighted in a prior report (link in Russian), one such instance involved a PDF reader app trojanized to drop the Anatsa banking malware. Upon execution, the app presented users with a fake request to install an update, which served as a front to stage the banking Trojan on the victim’s device.

Another notable case involves a loader we detected in the Cleanova app alongside several others. The malware sent requests to a command-and-control server containing telemetry gathered from various SDKs that track the installation source. A malicious payload was returned only for certain sources. This is a fairly interesting method for bypassing app store review processes while ensuring precise victim targeting. If an analytics SDK indicates that an arbitrary installation originated from a source outside the threat actors’ scope, the malicious logic remains dormant. This effectively hides the malware from app store scanners.

Mobile threat statistics

In Q2, the number of Android malware samples totaled 304,128. It remained steady compared to the previous reporting period.

While the number of newly discovered banking Trojan variants fell precipitously, they continued to dominate the threat landscape as they did in Q1. Notably, the share of Creduz malware family among identified banking samples has grown significantly despite low activity in victim telemetry. This discrepancy suggests the threat actors are actively iterating on the malware — likely testing new features or bypasses — by generating a high volume of builds before staging a broader campaign.

Within the adware category, the sharpest declines were observed in the HiddenAd and MobiDash families. Meanwhile, the proportion of users targeted by Trojan-Dropper malware increased, primarily driven by surges in banking droppers such as Trojan-Dropper.AndroidOS.Banker and Trojan-Dropper.AndroidOS.Mamont. The corresponding drop in the Trojan-Banker category is partially explained by a shift in tactics: several banking Trojans which are now being packed were subsequently reclassified as droppers.

The distribution of top malware families in Q2 largely mirrors the rankings from the previous reporting period. Newer variants of the Mamont banking Trojan climbed the leaderboards, displacing older iterations. This shift points to ongoing, active development of new variants by the threat actors behind the malware.

Mobile banking Trojans

In Q2, the total volume of Trojan-Banker applications dropped sharply compared to the previous quarter, totaling 93,574 installation packages.

Against the backdrop of this trend, the distribution shifted heavily toward Creduz Trojans. However, as noted earlier, this shift was not reflected in real-world attack metrics: virtually the entire leaderboard by proportion of targeted users continues to be dominated by diverse Mamont variants.

In the third quarter of 2025, we updated the methodology for calculating statistical indicators based on the Kaspersky Security Network. These changes affected all sections of the report except for the statistics on installation packages, which remained unchanged.

To illustrate the differences between the reporting periods, we have also recalculated data for the previous quarters. Consequently, these figures may significantly differ from the previously published ones. However, subsequent reports will employ this new methodology, enabling precise comparisons with the data presented in this post.

The Kaspersky Security Network (KSN) is a global network for analyzing anonymized threat information, voluntarily shared by users of Kaspersky solutions. The statistics in this report are based on KSN data unless explicitly stated otherwise.

The quarter in numbers

According to Kaspersky Security Network, in Q1 2026:

• More than 2.67 million attacks utilizing malware, adware, or unwanted mobile software were prevented.
• The Trojan-Banker category was the prevalent mobile malware threat with a 52.96% share of total detected applications.
• More than 306,000 malicious installation packages were discovered, including:
  • 162,275 packages related to mobile banking Trojans;
  • 439 packages related to mobile ransomware Trojans.

Quarterly highlights

The number of malware, adware, or unwanted software attacks on mobile devices decreased to 2,676,328 in Q1, down from 3,239,244 in the previous quarter.

The overall drop in attack volume stems primarily from a reduction in adware and RiskTool detections. Nonetheless, this trend does not equate to a lower risk for mobile users. As shown later in this report, the number of unique users targeted by these threats remained relatively stable.

In Q1, Synthient researchers identified a link between the notorious Kimwolf botnet and the IPIDEA proxy network. This network was later taken down in cooperation with GTIG.

In early 2026, we discovered several apps on Google Play and the App Store that contained a new version of the SparkCat crypto stealer.

The Trojan code, meticulously concealed, was embedded into the infected Android apps. The obfuscated malicious Rust library was decrypted using a Dalvik-like virtual machine custom-built by the attackers. The iOS version of the malware also underwent several changes; specifically, the attackers began leveraging Apple’s proprietary Vision framework for optical character recognition (OCR).

Mobile threat statistics

The number of Android malware samples saw a slight increase compared to Q4 2025, reaching a total of 306,070.

Following the surge in banking Trojan installation packages, the number of associated attacks also rose, causing Trojan-Banker apps to climb one spot in terms of their share of targeted users. Mamont variants emerged as the most prevalent banking Trojans, accounting for 73.5% of detections, with the rest of the users encountering Faketoken, Rewardsteal, Creduz, and other families.

Yet banking Trojans were still outpaced by adware and RiskTool-type unwanted apps when measured by the total number of affected users. Despite a decrease in their share of installation packages, these two app types retained their positions as the top two threats by attack volume. The most common adware detections involved HiddenAd (44.9%) and MobiDash (38.1%), while most frequently seen RiskTool apps were Revpn (67%) and SpyLoan (20.5%).

The pre-installed Triada.ag backdoor rose to the top spot; it is similar to the older Triada.z version we documented previously. Because the same variant was pre-installed across a wide range of devices, the total number of affected users is aggregated. Consequently, Triada outpaced even Mamont, as users encountered a variety of Mamont variants, causing the share of that banking Trojan to spread across multiple rows. Other pre-installed Triada variants (Triada.z, Triada.ae, Triada.ab, and Triada.ad) also made the rankings. Furthermore, we observed increasing activity from the Keenadu.a backdoor, while diverse variants of the embedded Triada Trojan remained in the rankings.

Mobile banking Trojans

Q1 2026 saw a characteristic rise in mobile banking Trojan activity, with the number of packages totaling 162,275, a 50% increase compared to the prior quarter.
