Background for this topic.

Shutting down is the orderly termination and powering off of a computer, server, or network device; the term can also describe taking a service or system offline. A normal operating-system shutdown closes applications, writes pending data, and stops services, while a forced power-off may leave files or storage in an inconsistent state. Powering down is not the same as securely erasing data or removing an attacker’s persistence.

During incident response, shutting down can halt active malicious processes, but it also destroys volatile evidence such as memory-resident code and may prevent investigators from examining the running system. Teams should generally document the decision and apply appropriate network containment or evidence-collection procedures first, unless immediate isolation is necessary. For routine shutdowns, access controls should restrict who can power systems off, and full-disk encryption remains important because a powered-off device or removed drive may still expose stored data if stolen.

The Dark Nexus Between Harm Groups and ‘The Com’

A cyberattack that shut down some of the top casinos in Las Vegas last year quickly became one of the most riveting security stories of 2023: It was the first known case of native English-speaking hackers in the United States and Britain teaming up with ransomware gangs based in Russia. But that made-for-Hollywood narrative has eclipsed a far more hideous trend: Many of these young, Western cybercriminals are also members of fast-growing online groups that exist solely to bully, stalk, harass and extort vulnerable teens into physically harming themselves and others.

Ten of the domains are reincarnations of DDoS-for-hire services the FBI seized in December 2022, when it charged six U.S. men with computer crimes for allegedly operating booters.
