The source code for version 3 of the ERMAC Android banking trojan malware has been leaked online, exposing its internal workings and targeting capabilities. This leak poses a significant threat to global financial security and highlights the importance of staying informed about emerging threats like ERMAC.
Researchers at Hunt.io discovered a leaked source code for ERMAC v3 Android banking trojan malware. The leak exposes internal workings and infrastructure used by its operators to deploy the malware. Ermac v3.0 targets sensitive user information in over 700 apps, surpassing the previously documented 467 apps targeted by ERMAC v2.0. The malware incorporates various form-injection techniques and uses AES-CBC encryption for secure communication. There are significant operational security (opssec) failures, including hardcoded tokens and default root credentials. The leak erodes trust in the malware-as-a-service platform, making it easier for attackers to use this malicious software without fear of detection or law enforcement interference.
In a concerning turn of events, researchers at Hunt.io have discovered that the source code for version 3 of the ERMAC Android banking trojan malware has been leaked online. This leak exposes the internal workings of the malware-as-a-service platform and the infrastructure used by its operators to deploy this malicious software.
The discovery was made in an open directory while scanning for exposed resources in March 2024. The researchers found an archive named Ermac 3.0.zip, which contained the malware's code, including its backend, frontend panel, exfiltration server, deployment configurations, and a trojan builder and obfuscator. The source code was analyzed by Hunt.io researchers, revealing significant enhancements to the malware's targeting capabilities compared to previous versions.
According to the report, ERMAC v3.0 now targets sensitive user information in over 700 banking and shopping apps, surpassing the previously documented 467 apps targeted by ERMAC v2.0. This increase in targeting capability makes it easier for attackers to steal personal data from unsuspecting users.
Furthermore, the leaked source code reveals that ERMAC v3.0 incorporates various form-injection techniques to intercept user input and inject malicious code. The malware also uses AES-CBC encryption for secure communication between its backend server and clients. These enhancements make it more challenging for security systems to detect and prevent ERMAC infections.
In addition to the technical details, researchers also found several major operational security (opssec) failures in the leaked source code. The operators had hardcoded JWT tokens and default root credentials in their system, which made it easier for anyone with access to manipulate or disrupt ERMAC panels. Furthermore, the panel names, headers, package names, and other operational fingerprints left little doubt about attribution and enabled the researchers to map the infrastructure used by the threat actors.
The implications of this source code leak are far-reaching. The exposure of ERMAC v3.0's capabilities erodes trust in the malware-as-a-service platform, making it easier for attackers to use this malicious software without fear of detection or law enforcement interference. Furthermore, the leaked source code will likely attract the attention of other threat actors, who may attempt to modify and improve upon the existing ERMAC malware to evade detection.
As a result, security threat detection solutions are likely to become more sophisticated in detecting and preventing future ERMAC infections. This increased vigilance is essential for protecting users' sensitive information from these malicious apps.
In conclusion, the leak of ERMAC v3.0's source code has significant implications for global financial security. As such, it is crucial that individuals and organizations remain vigilant in their efforts to detect and prevent malware infections. By staying informed about emerging threats like ERMAC, users can take proactive steps to protect themselves from these types of cyber attacks.
