Reddit TradingView Lures Deliver Vidar and AMOS Stealers

· Original article ↗

Summary

A threat actor used Reddit posts promoting cracked TradingView builds to distribute Vidar on Windows and AMOS on macOS. The active campaign used hijacked websites, password-protected archives, and social engineering to steal credentials and other data.

Key points

  • The campaign used aged or compromised Reddit accounts and hijacked or newly created subreddits to promote fake TradingView Premium downloads; warning comments were deleted.
  • Payloads were hosted on compromised legitimate business websites and delivered in password-protected archives using passwords such as github and codeberg.
  • Windows downloads used a 784 MB executable padded with null bytes; an embedded script reassembled and launched the Vidar stealer.
  • The macOS payload decrypted and ran an AMOS stealer that harvested browser credentials, cookies, wallet files, Keychain data, and other information.
  • The activity was ongoing at the time of the report, with payload URLs and subreddits rotated as they were flagged.
  • The report recommends blocking the identified distribution domains and hunting for suspicious Reddit browsing followed by large downloads, along with platform-specific endpoint behaviors.
  • Distribution domains included fotoflux[.]com, ghatreh[.]co, hitechprovider[.]com, techadapt[.]io, and qwayglobalventures[.]com.

Attack Vectors
  • Malicious Reddit posts in hijacked or newly created subreddits promoted cracked TradingView Premium downloads using aged or compromised accounts and coordinated comments.
  • Payloads were delivered as password-protected ZIP archives hosted on compromised legitimate company websites; the Windows download used a nested archive.
  • Windows execution used an oversized executable, a self-extracting cabinet, and an obfuscated batch script to reassemble and launch Vidar.
  • The macOS download masqueraded as a TradingView installer. Its binary decrypted and executed an AppleScript payload that installed AMOS and harvested credentials and other data.
  • macOS installation instructions directed users to allowlist the blocked application in Privacy and Security settings.
Defensive Notes
  • Block the identified distribution domains using web proxy and DNS controls.
  • Consider blocking password-protected ZIP and 7z archives at email and web gateways.
  • Hunt for Reddit browsing followed by a large ZIP download from an unrelated domain.
  • On Windows, monitor for wextract.exe spawning cmd.exe with delayed variable expansion, unusually large executables with bloated resource sections, and batch scripts using sequential copy /b operations.
  • On macOS, monitor unsigned or ad-hoc signed applications launching osascript or calling system(), unexpected dscl . authonly calls, ditto creating ZIP archives in temporary directories, and unexpected outbound HTTP POST traffic.
  • Treat suspected infections as compromises and initiate incident response; the article advises considering saved passwords, session cookies, wallet keys, and locally stored tokens exposed.
