The US government has recommended a series of steps that critical infrastructure operators should take to prevent distributed-denial-of-service attacks. The joint guide, entitled Understanding and Responding to Distributed Denial-Of-Service Attacks [PDF], distinguishes between denial-of-service and DDoS attacks.
The FBI warned of increases in crypto scams in March last year, saying most begin with some sort of social engineering, like a romance or confidence scam, which then evolve into crypto investment fraud. The total losses from investment fraud also beat those incurred by ransomware across the country, according to the latest report [PDF] from the FBI's Internet Crime Complaint Center.
The BlackCat ransomware gang is pulling an exit scam, trying to shut down and run off with affiliates' money by pretending the FBI seized their site and infrastructure. "The ransomware gang started the exit-scam operation on Friday, when they took their Tor data leak blog offline. On Monday, they further shut down the negotiation servers, saying that they decided to turn everything off, amid complaints from an affiliate that the operators stole a $20 million Change Healthcare ransom from them."

ALPHV has made a habit of going after critical infrastructure targets, and last week claimed responsibility for an attack on the company operator of the Canadian Trans-Northern Pipelines, allegedly stealing around 190GB of data.
The US government today said it disrupted a botnet that Russia's GRU military intelligence unit used for phishing expeditions, spying, credential harvesting, and data theft against American and foreign governments and other strategic targets. Then the GRU spying team used Moobot to install their own bespoke scripts and files that repurposed the botnet, thus "Turning it into a global cyber espionage platform," according to the Feds.
