Why this matters:

• The RobinHood ransomware group has crippled government systems and hospitals, highlighting the real-world damage of cybercrime.
• A guilty plea from a state-backed actor sends a powerful message about the consequences of cyberattacks.
• This case reinforces the urgent need for cybersecurity investment across public and private sectors.

An Iranian national has pleaded guilty in a North Carolina federal court to orchestrating a series of RobinHood ransomware attacks that disrupted municipal services and healthcare systems across the United States. The defendant now faces up to 30 years in prison for conspiracy to commit fraud, computer intrusion, extortion, and money laundering.

The RobinHood ransomware group gained notoriety in May 2019 after crippling Baltimore's IT infrastructure for weeks. Their attacks extended to cities like Greenville, North Carolina; Gresham, Oregon; and Yonkers, New York, as well as organizations such as Meridian Medical Group and Berkshire Farm Center. The attackers often accessed victim networks using administrator accounts or exploiting vulnerabilities, manually deploying ransomware, and demanding payment through Tor dark web sites. In later campaigns, they also engaged in data theft, using the threat of leaks as additional leverage against victims. 

Notably, the group employed a "Bring Your Own Vulnerable Driver" (BYOVD) technique, utilizing a legitimate but vulnerable Gigabyte driver (gdrv.sys) to disable antivirus software, allowing their ransomware encryptor to operate without interference. The attackers used virtual private servers in Europe, VPNs, and cryptocurrency mixers to evade law enforcement. 

This case underscores the evolving tactics of ransomware groups and the importance of robust cybersecurity measures. Organizations are encouraged to implement comprehensive security protocols, including regular phishing simulations and employee training, to mitigate such threats.
