International Joint Operation Cripples Ragnar Locker Ransomware Ring

In a decisive collaboration against cybercrime, law enforcement agents from three continents have dismantled the infrastructure of the notorious Ragnar Locker ransomware operation.

This remarkable achievement comes on the heels of the Ukrainian Cyber Alliance's self-proclaimed victory over the Trigona ransomware operation.

Background

Ragnar Locker has menaced the internet since late December 2019, with the FBI and CISA issuing a stern warning in a joint flash alert in March 2022 about the group's activities.

The alert elucidated, "As of January 2022, the FBI has identified at least 52 entities across 10 critical infrastructure sectors affected by RagnarLocker ransomware, including entities in the critical manufacturing, energy, financial services, government, and information technology sectors." It was further revealed that "RagnarLocker ransomware actors work as part of a ransomware family, frequently changing obfuscation techniques to avoid detection and prevention."

The Takedown

Law enforcement agencies from the Czech Republic, Europe, France, Germany, Italy, Japan, Latvia, the Netherlands, Spain, and the US joined forces to bring down the operational capability of the Ragnar Locker gang.

This joint action saw the seizure of the gang's Tor negotiation and data leak sites on Thursday. The affected websites now display a message announcing their seizure as part of this international law enforcement action against the Ragnar Locker group.

Unlike many of its nefarious counterparts, Ragnar Locker operated semi-privately, refraining from the Ransomware-as-a-Service model, which actively recruits outside affiliates. Instead, they collaborated with external pentesters to infiltrate networks, focusing mainly on corporate networks, moving laterally through them, and pilfering data before encrypting devices.

The stolen files were then employed in double-extortion campaigns, an insidious tactic to maximize financial gain by charging victims twice - once for decryption and recovery and again to prevent public data leakage.

Protecting Against Ransomware

While large enterprises are often the primary targets of ransomware attacks, individuals are not spared these threats. Here are a few tips to bolster your cybersecurity:

1. Regular Updates: Keep your operating system, software and anti-virus programs up-to-date to patch security vulnerabilities.
2. Educate Yourself: Be knowledgeable about phishing scams and avoid opening unsolicited emails or clicking on suspicious links.
3. Backup Data: Regularly back up your data to an external hard drive or a secure cloud service.
4. Use Strong Passwords: Employ complex passwords and change them regularly. Consider using a password manager to keep track of them.
5. Enable Multi-Factor Authentication: Where possible, use multi-factor authentication to add an extra layer of security.
6. Use Specialized Security Software: Security solutions like Bitdefender Ultimate Security can help thwart ransomware attacks and keep your data safe from all digital threats.

The demise of the Ragnar Locker operation marks a significant win in the battle against cybercrime. However, as the digital landscape evolves, so does the sophistication of cyber threats. Staying informed and adopting robust cybersecurity practices are crucial to safeguarding one's digital realm.
