CISA usually puts out an official Shields Up! advisory on long U.S. holiday weekends (based on the historical pattern of increased cyber activities directed at the U.S. during those weekends).

Although this weekend was not a holiday weekend, based on the recent cyber incidents and strategic threat vector activity itemized in this post, we put up the Shields Up! advisory starting on Friday to highlight recent CISA CSAs and Joint CSAs regarding ransomware, DNA resolution, recent targeting of the defense industrial base and other information threat vectors (Chinese hacking activity, etc.).
