What is Vidar malware?
Vidar malware is an information-stealing trojan designed to exfiltrate sensitive data like passwords, credit card info, and cryptocurrency wallet details. It is often used by cybercriminals as a precursor to larger attacks, such as ransomware deployment. Known for its stealthy operations, Vidar malware often operates under aliases and adapts its behavior to evade detection, making it a high-risk threat in today's cyber landscape.
When was Vidar first discovered?
Vidar malware was first observed in late 2018 and documented as a new variant of other information-stealing malware such as Arkei. The cybersecurity community quickly flagged its effectiveness in targeting individuals and organizations globally.
Who created Vidar malware?
The identities behind Vidar malware remain unknown. It is suspected that the malware is distributed by underground threat actors or groups through illicit platforms. Its availability on dark web forums facilitates its use by various attackers.
What does Vidar target?
Vidar malware primarily targets Windows operating systems, with a preference for individual workstations and enterprise endpoints. Its victims span across sectors, including finance, healthcare, and retail, and it shows no geographical bias, posing a worldwide threat.
Vidar distribution method
Vidar malware is distributed using techniques such as phishing emails, malvertising, and exploit kits. Additionally, it is embedded in cracked software or bundled with legitimate-looking applications, tricking users into downloading malicious files.
Technical analysis of Vidar malware
Vidar malware operates by infiltrating systems and deploying a payload to extract sensitive data. Its infection chain often starts with an obfuscated loader, followed by data exfiltration commands targeting browsers, FTP clients, and cryptocurrency wallets. Vidar exhibits persistence by modifying registry keys, and it avoids detection by using sandbox-evasion techniques.
