website used by hackers responsible for a breach at UnitedHealth Group (UNH.N), opens new tab has been replaced by a notice saying it has been seized by international law enforcement.
But at least one of the agencies allegedly responsible said it had nothing to do with the seizure, raising the possibility that the hackers - who also go by the moniker ALPHV - faked their own takedown.
A message posted to the website of the Blackcat hacking gang on Tuesday said it had been impounded "as part of a coordinated law enforcement action" by U.S. authorities and other law enforcement agencies. Among the logos of non-American agencies involved were those of Europol and Britain's National Crime Agency.

The ALPHV/BlackCat ransomware gang has shut down its servers amid claims that they scammed the affiliate responsible for the attack on Optum, the operator of the Change Healthcare platform, of $22 million.
