Give thanks for IT staff © AP Photo/Mark J. Terrill, File The FBI and the Cybersecurity and Infrastructure Security Agency (CISA) on Monday warned organizations to be on guard against cyber threats, particularly ransomware attacks, over the Thanksgiving holiday. In a joint alert, the agencies noted that while there were currently no “credible threats” identified, hackers had previously launched attacks during holiday weekends when workers are often at home and less likely to be paying close attention to network security. “Recent 2021 trends show malicious cyber actors launching serious and impactful ransomware attacks during holidays and weekends, including Independence Day and Mother’s Day weekends,” the alert said. Previous track record: The ransomware attack that crippled Colonial Pipeline this year was discovered just ahead of Mother’s Day weekend, while meat producer JBS USA was hit by a separate attack over Memorial Day weekend. IT company Kaseya was hit by a ransomware attack, potentially compromising up to 1,500 other businesses, during the Fourth of July holiday weekend. The FBI and CISA previously put out an alert ahead of Labor Day weekend this year urging organizations to be on the lookout for cyber threats, with the holiday ultimately seeing no major cyberattacks on U.S. businesses.
