Four ransomware cyberattacks have struck U.S. municipalities this December, and the month is not over yet. The Avast Blog reported on the Dec. 7 attack against Pensacola, Fla., but since then, ransomware has also hit New Orleans (Dec. 13), the Sacramento suburb of Galt, Calif. (Dec. 16), and the St. Lucie County Sheriff’s Department in Florida (Dec. 17). It is unknown if these attacks are related, but they occur as the trend of taking small government systems hostage continues to increase.
