Summary
Vidar Stealer is a malware written in C++ that is derived from the Arkei malware. First seen in 2018, Vidar has continued to evolve as its developers attempt to stay under the radar. Vidar uses multiple avenues of infection to compromise victims; phishing and spam email campaigns as well as disguising itself in cracked software packages that often get downloaded by unsuspecting victims looking for free software. Once a victim has been compromised, Vidar attempts to steal banking details, saved passwords, browser history, login credentials, system, and location details as well as more recently crypto wallets. Other capabilities include theft of 2FA data, screen captures, stealing information from messaging software and history from browsers including TOR. Vidar is also location aware and has a set of countries which it is instructed not to compromise.
The McAfee Enterprise Advanced Threat Research team will continue to monitor and update the Vidar Stealer event and disseminate information that is deemed appropriate regarding Vidar Stealer and any potential victims.

Minimum set of Manual Rules to improve protection to block this campaign
IMPORTANT: Always follow best practices when you enable new rules and signatures.
When you implement new rules or signatures, always set them to Report mode first and check the alerts generated. Resolve any issues that arise and then set the rules to Block. This step mitigates against triggering false positives and allows you to refine your configuration.
For more information, see KB87843 - List of and best practices for Endpoint Security Dynamic Application Containment rules.
