Hackers may use exit scams by disappearing from their online haunts, such as dark web marketplaces and communication channels. They may also take down websites associated with their group and replace them with fabricated statements. To avoid suspicion, hackers may claim that law enforcement disrupted their operations, even if it's not true. They may also stop communicating with victims and collaborators, leaving them in the dark about stolen data, ransom payments, or promised services.
It gets weird when it's feds larping.
