MegaFon Reports 34% Rise in Russian Mobile Malware Infections Driven by Android Trojans

MegaFon monitoring data shows a 34% year-over-year increase in Russian users with detected mobile malware during summer 2026, with the sharpest spike of 77% recorded in August. The growth is primarily attributed to Android trojans capable of installing apps without user consent, intercepting notifications, enabling remote access, and stealing personal data. At the same time, blocked suspicious calls dropped significantly, by 31% in June, 41% in July, and 75% in August, which the operator links to state and corporate anti-fraud measures. Scammers are adapting by hijacking messenger accounts through social engineering, malware, and even rental schemes, often combining calls with fake app installations that deploy spyware. Phishing remains active, with 30% of detected malicious resources tied to investments and crypto, 21% to social networks and messengers, and 9% to harmful APK files. Director Sergey Khrenov noted that smartphones are increasingly used as tools by the attackers themselves in these hybrid schemes.

MegaFon monitoring has revealed a sharp 34% year-over-year increase in the number of Russian users whose smartphones were found to contain mobile malware during the summer of 2026.

The most significant surge occurred in August, when detections rose by 77% compared with the same month last year. The primary threat consists of Android trojans that can silently install applications, intercept notifications, provide remote access to attackers, and exfiltrate personal data.

While mobile malware activity grew, the number of blocked suspicious calls declined markedly: 31% fewer in June, 41% fewer in July, and 75% fewer in August year over year. In September the figure remained 73% below the previous year’s level. MegaFon attributes this drop to coordinated government and corporate efforts against telephone fraud.

However, the reduction in blocked calls does not indicate that scammers have ceased operations. Attackers are increasingly relying on compromised messenger accounts obtained through social engineering, malware deployment, and even offers to rent out user credentials.

According to Sergey Khrenov, Director of the relevant department at MegaFon, hybrid attacks are becoming common: during a fraudulent call, victims are persuaded to install what appears to be a legitimate application, which in reality is spyware that allows attackers to monitor the target and adjust their tactics in real time.

Phishing activity also remains high. Among identified malicious resources, 30% are linked to investments and cryptocurrencies, 21% to social networks and messengers, and 9% to potentially harmful APK files. These categories frequently overlap, turning the victim’s own smartphone into an instrument for further fraud.
