Ransomware

Ransomware has continued to be part of the 24-hour news cycle as another significant attack against critical infrastructure took place this week.

This week's most notable attack was an REvil ransomware attack against JBS, the world's largest meat supplier. This attack led to disruption on numerous meat production sites while the company restored their data from backup.

Due to these attacks, the White House sent an open letter to businesses warning them to take ransomware seriously. The DOJ has also begun to treat ransomware attacks at a similar priority as terrorism.

This week's other attacks include ones against Fujifilm, the Massachusetts Steamship Authority, and UF Health Central Florida hospitals.

Finally, the DOJ announced Friday night that they arrested and charged a Latvian woman for developing a ransomware module for the TrickBot malware. This ransomware module was never used outside of development, allowing the FBI to prevent further attacks.
