 Evolution of Raven Stealer

1. Initial Appearances (2022–2023)

   • Sold on underground markets as a MaaS (Malware-as-a-Service).

   • Priced affordably to attract low-level cybercriminals.

2. Expansion (2024)

   • Added modules for Telegram session hijacking, crypto wallet targeting, and anti-sandbox features.

   • Widely distributed via phishing attachments, cracked software installers, and malicious advertising.

3. Current Trends (2025)

   • Multiple variants circulating with improved persistence mechanisms.

   • Integrated with botnets for large-scale credential harvesting.

   • Often bundled with cryptojacking payloads for secondary monetization.

 Technical TTPs

Tactic	Technique	Raven Stealer Behavior
Initial Access	Malvertising, phishing attachments	Fake PDF invoices, cracked games
Execution	PowerShell loaders, EXE trojans	Dropped into temp folders
Persistence	Registry Run keys, scheduled tasks	Auto-start on reboot
Defense Evasion	Checks for VM/sandbox, obfuscation	Kills process if analysis detected
Credential Access	Browser credential theft	Chrome, Edge, Firefox
Exfiltration	Encrypted HTTP POST to C2	Sends stolen credentials + wallet seeds
