Vidar Stealer

Vidar Stealer is a prolific infostealer malware that operates on a malware-as-a-service model, sold through ads and forums on the dark web and Telegram groups. It's designed to exploit and damage computer systems by stealing personal information, disrupting operations, or holding data for ransom. The malware can infect systems through suspicious downloads, emails, websites, or even malicious Google Search ads, often without the user's knowledge. Over time, its distribution system has evolved from traditional spam campaigns and cracked software to more sophisticated methods. The malware has been associated with various other threats such as BatLoader, which delivers additional malware including Vidar Stealer and ISFB, and AceCryptor, which distributes samples from many different malware families including Vidar Stealer. Analysts have also assessed that RisePro is very likely a clone of Vidar Stealer. If users interact with malware-serving ads, they could unknowingly download and deploy harmful files onto their devices, including Rilide Stealer, Vidar Stealer, IceRAT, and Nova Stealer. Vidar Stealer is part of an extensive network of cybercriminal activities, including account takeover (ATO), online banking theft, and financial fraud. It competes with other prominent malwares such as Azorult, Redline, Racoon, and Meduza in these illicit activities. Phishing campaigns have been discovered targeting the hospitality sector, using booking-related email messages to distribute information stealer malware like RedLine Stealer or Vidar Stealer, further indicating the broad reach and impact of this threat.
