According to US-based tech website bleepingcomputer.com, the forum boasts to have more than 150,000 users and over 20,000 tools listed in its forums. The hacker breached the site and uploaded samples of its database online, along with the ransom demand. The attacker said if the victim fails to to deliver the ransom, he would share the data on the site's administrator with the US authorities such as the Federal Bureu of Investigation (FBI), Department of Homeland Security (DHS), Department of Justice (DOJ) and Department of Treasury (DoT). "To prove the validity of his claims, the hacker shared an image of the Basetools admin panel and an image containing the site admin's login details and IP address," the report said.
