Android users face a growing threat as the Chameleon Banking Trojan, initially identified in early 2023, evolves with alarming new capabilities. The latest update of this malicious app, detected by cybersecurity researchers at ThreatFabric, includes the ability to block fingerprint authentication, potentially exposing users’ PIN codes or passwords.

Chameleon’s earlier version was adept at targeting banking and cryptocurrency applications, using a proxy feature for actions like Account Takeover (ATO) and Device Takeover (DTO) attacks. In Australia, it posed as official institutions, while in Poland, it masqueraded as popular banking apps. The updated version, detected in the UK and Italy, spreads under the guise of Google Chrome downloads.
The malware’s new capabilities include guiding users through a process to enable Accessibility Services and disabling biometric prompts in favor of PIN authentication. This not only allows the trojan to unlock devices at will but also enables the theft of PINs and passwords through a keylogger.
Chameleon’s sophistication extends to improved task scheduling features and adaptation to the user’s app usage patterns. It may inject features into apps or collect data about foreground apps, presenting a more dangerous and advanced threat compared to its early 2023 variant.
Google, acknowledging the threat, reassures users that Play Protect will guard against Chameleon. However, user vigilance is crucial—avoid downloading apps from untrusted sources, refrain from clicking on suspicious links, and exercise caution with devices lacking Google Play Services. Taking these precautions is the best defense against the evolving threats within the Android ecosystem.
