A malicious program that can infect computers running Microsoft Windows OS. It is designed to steal logins, passwords and other confidential information. Several modifications were found. They were also detected as Trojan.PWS.Stealer.23012. The program is written in Python.

Cases of Trojan distribution via Yandex.Disk have been reported; links to the files were published as comments to YouTube videos. The malware was distributed as a self-unpacking RAR SFX archive with the following content:

_ctypes.pyd
_hashlib.pyd
_socket.pyd
_sqlite3.pyd
_ssl.pyd
bz2.pyd
CRYPT32.dll
library.zip
main.exe

select.pyd
sqlite3.dll

win32wnet.pyd

The Trojan itself was implemented as the main.exe application (script in Python using the py2exe utility), other files are necessary for its operation. All gathered information is saved in the C:/PG148892HQ8 folder. The folder contents are then packed into the spam.zip archive, which is sent to the cybercriminals’ server along with the data on the infected device location. The Trojan gathers the following information on an infected device:

  • cookies stored by the Vivaldi, Chrome, YandexBrowser, Opera, Kometa, Orbitum, Dragon, Amigo, and Torch browsers;
  • saved logins/passwords from the same browsers;
  • screenshot
  • files with “.txt”, “.pdf”, “.jpg”, “.png”, “.xls”, “.doc”, “.docx”, “.sqlite”, “.db”, “.sqlite3”, “.bak”, “.sql”, and “.xml” extensions from Windows Desktop
