The agency says that a small amount of personal data about USDA employees may have been exposed in the incident.

Onix Group, a Pennsylvania-based real estate firm that also operates a chain of substance misuse treatment centers, has reported a data breach to the Department of Health and Human Services (HHS). The company said that a ransomware attack discovered on March 27 had corrupted some systems and resulted in data exfiltration. Onix’s investigation ultimately determined that an unauthorized actor had accessed Onix’s network between March 20 and March 27. The stolen files contained employee information including names, Social Security numbers, direct deposit information and health plan enrollment information.

The Louisiana Office of Motor Vehicles has disclosed that it too has fallen victim to Cl0p and the MOVEit exploit. The agency said that it expects that every Louisianan with a state-issued driver’s license, ID, or car registration likely had their data exposed to the threat actors. The OMV says that those impacted likely had personal data exposed including their name, address, social security number, birth date, height, eye color, driver’s license number, vehicle registration information and handicap placard information. Many other U.S. federal, state and local agencies have also been swept up in the MOVEit breach. The Oregon Department of Motor Vehicles released a similar statement noting that 3,500,000 Oregonians with an ID or driver’s license had similar data exposed too.

A newer ransomware group named Rhysida has leaked a trove of documents that they claim to have stolen from the network of the Chilean Army (Ejército de Chile). The Chilean Army did confirm on May 29 that its systems were impacted in a security incident detected over the weekend on May 27 and data was likely stole. Interestingly, in the days following the announcement of the hack, an Army corporal was arrested and charged for his involvement in the incident, suggesting that the ransomware was deployed by a malicious insider. Rhysida ransomware has since published around 360,000 Chilean Army documents on its dark web leak site and claimed that they comprise about 30% of the data that was stolen. The incident is under investigation by Chile’s Computer Security Incident Response Team (CSIRT) of the Joint Chiefs of Staff and the Ministry of National Defense.

Oil and gas behemoth Shell has announced that it too is a victim of Cl0p’s cybercrime spree using the MOVEit exploit.

However, Cl0p posted that Shell was refusing to negotiate on its site last Friday.
