New Android Malware SeedSnatcher and FvncBot Found By Experts
New Android malware found
Researchers have revealed details of two Android malware strains called SeedSnatcher and FvncBot. Upgraded version of ClayRat was also found in the wild.
About the malware
FvncBot works as a security app built by mBank and attacks mobile banking users in Poland. The malware is written from scratch and is different from other banking trojans such as ERMAC whose source codes have been leaked.
According to Intel 471, the malware "implemented multiple features including keylogging by abusing Android's accessibility services, web-inject attacks, screen streaming and hidden virtual network computing (HVNC) to perform successful financial fraud."
Like the Albiriox banking malware, this trojan is shielded by a service called apk0day that Golden Crypt offers.
Attack tactic
After the dropper app is launched, users are asked to download a Google Play component for security of the app. But in reality, it deploys the malware via session-based approach which other actors adopt to escape accessibility restrictions on Android devices version 13 and above.
According to Intel 471, "During the malware runtime, the log events were sent to the remote server at the naleymilva.it.com domain to track the current status of the bot." After this, the malware asks victims for accessibility services permission, it then gets privileges and connects to an external server.
Malware capabilities
FvncBot also triggers a text mode to analyze the device screen layout and content even in cases where an app doesn't allow screenshots by setting the FLAG_SECURE option.
Experts don't yet know how FvncBot is getting widespread, but Android banking trojans leverage third-party app stores and SMS phishing as a distribution vector.
According to Intel 471, "Android's accessibility service is intended to aid users with disabilities, but it also can give attackers the ability to know when certain apps are launched and overwrite the screen's display."
The firm added that the sample was built to "target Polish-speaking users, it is plausible we will observe this theme shifting to target other regions or to impersonate other Polish institutions."
Beyond the immediate threat to banking and cryptocurrency users, the emergence of FvncBot, SeedSnatcher, and the upgraded ClayRat underscores a troubling evolution in mobile-malware design: an increasing shift toward “full-device takeover” rather than mere credential theft. By exploiting legitimate features, such as Android’s accessibility services, screen-streaming APIs, and overlay permissions, these trojans can invisibly hijack almost every function of a smartphone: logging keystrokes, intercepting SMS-delivered 2FA codes, capturing screen contents even when apps try to block screenshots, and executing arbitrary commands as though the real user were interacting with the device.
This marks a new class of threat in which a compromised phone becomes a proxy tool for remote attackers: they don’t just steal data, they can impersonate the user, conduct fraudulent transactions, or monitor every digital activity. Hence, users worldwide, not only in Poland or crypto-heavy regions, must remain vigilant: the architecture these threats use is platform-wide, not region-specific, and could easily be repurposed for broader global campaigns.
