Executive Summary
Recorded Future analysts continue to monitor the activities of the FIN7 group as they adapt and expand their cybercrime operations. Gemini has conducted a more in-depth investigation into these types of attack after a Gemini source provided analysts with the file “sketch_jul31a.ino”, which was linked to FIN7’s BadUSB attacks.
Key Findings
FIN7 used an Arduino sketch file called “sketch_jul31a.ino” to install malware on USB devices as part of BadUSB attacks.
Attack Analysis
Gemini specialists conducted the analysis of the file “sketch_jul31a.ino”. “.INO” is a file extension associated with the Arduino microcontroller programming platform, while “sketch” is the platform’s term for a program.
Outlook and Conclusions
The use of trojanized USB devices for keystroke injection is not a new technique, even for FIN7. Typically the attack targets specific persons with access to the computer systems of the intended victim company.
