FBI and CISA warns: Ransomware attacks on weekends and holidays

[German]The US security agency CISA and the FBI have issued a warning stating that ransomware gangs are now targeting weekends and holidays for their attack campaigns. This tends to thin out IT staff to monitor networks, and attacks are not noticed or are more difficult to defend.

I already pointed out the problem in March 2020 in my German blog postRansomware schlägt Nachts und am Wochenende zu. Attacks with ransomware probably happen mainly at night or on weekends, when no administrator or IT manager is available.

The above tweet  now picks up on a warning that Catalin Cimpanu elaborates on in this article. Research shows that the three major ransomware attacks in 2021 were precisely timed to coincide with weekends and holidays.
