“Infostealer” malware have¬†been in the wild for a long time now. Once the computer’s victim is infected, the goal is to steal “juicy” information like passwords, cookies, screenshots, keystrokes, and more. Yesterday, I spotted an interesting sample. It’s delivered through an FTP connection. The file (SHA256:2bf9a44bd546e0fd1448521669136220dc49146b0f3a5cd7863698ac79b5e778) is unknown on VirusTotal.

The malware behavior is pretty simple: It scans the complete drive for interesting files. Here is an example: “*pass*.txt”:

I also discovered that it searches for other files:

*seed*.txt
*ledger*.txt
*trezor*.txt
*metamask*.txt
*bitcoin*.txt
*words*
*wallet*.txt
*.kbdx

Simple but efficient. C2 communications are performed with slimtvsocico[.]fun.
