The state agencies of Maine had fallen victim to cybercriminals who exploited a vulnerability in the MOVEit file transfer tool, making them the latest addition to the growing list of entities affected by the massive hack involving the software. In a notice the government has published about the cybersecurity incident, it said the event impacted approximately 1.3 million individuals, which basically make up the state’s whole population. The state first caught wind of the software vulnerability in MOVEit on May 31 this year and found that cybercriminals were able to access and download files from its various agencies on May 28 and 29.
While the nature of stolen data varies per person based on their interaction with a particular agency, the notice says that the bad actors had stolen names, Social Security numbers, birthdates, driver’s license and state identification numbers, as well as taxpayer identification numbers. In some cases, they were also able to get away with people’s medical and health insurance information. Over 50 percent of the stolen data came from the Maine Department of Health and Human Services, followed by the Maine Department of Education.
The state government had blocked internet access to and from the MOVEit server as soon as it became aware of the incident. However, since the cybercriminals were already able to steal residents’ information, it’s also offering two years of complimentary credit monitoring and identity theft protection services to people whose SSNs and taxpayer numbers were compromised. As TechCrunch notes, the Clop ransomware gang that’s believed to be behind previously reported incidents, has yet to release data stolen from Maine’s agencies.
Clop took credit for an earlier New York City Department of Education hack, wherein the information of approximately 45,000 students was stolen. Cybercriminals exploiting the vulnerability haven’t only been targeting the government, though, but also companies around the world. Sony is one of them. There’s also Maximus Health Services, Inc, a US government contractor, whose breach has been the biggest MOVEit-related incident, so far.
The Securities and Exchange Commission is already investigating MOVEit creator Progress Software, though it only just sent the company a subpoena in October and is still in the “fact-finding inquiry” phase of its probe.
