The infamous ransomware group Blackcat, also recognized as ALPHV, is issuing a threat to disclose classified and top-secret files from various U.S. intelligence agencies, including the FBI.

The group alleges to have breached a technology company and, in a post on the dark web on Tuesday, asserted that it has successfully obtained 300GB of data from the Technica Corporation.

According to the company’s website, Technica Corporation is dedicated to supporting the Federal Government and its mission to defend and protect American citizens.

“Leaks of classified and top secret documents,” the group wrote on its blog. “Documents related to the FBI and other US intelligence agencies. If Technica does not contact us soon, the data will either be sold or made public.”

The blog post featured a purported sample of the data, consisting of 29 distinct documents, as reported by the Daily Dot.

This included contracts from the Department of Defense and sensitive information such as names, phone numbers, and Social Security numbers of numerous Technica employees.

Merely a month ago, the FBI, along with various global intelligence agencies, effectively dismantled ALPHV’s dark web homepage.

In response, ALPHV promptly reestablished its site in an alternate location on the dark web.
