CISA and Coast Guard Cyber Command Warn of Ongoing Log4Shell Attacks


In March 2021,  OODA CTO Bob Gourley had an OODAcast conversation with Ellen McCarthy.  Ellen’s career began at the office of Naval Intelligence. She then moved to Norfolk and the Atlantic Intelligence Center and would later lead all intelligence activities for the US Coast Guard as their director of intelligence.  McCarthy then joined DoD’s office of the undersecretary of defense for intelligence working strategy and human capital management. Later she led the nonprofit public-private partnership INSA (the intelligence and national security alliance), helping make that organization what it is today.  She returned to government service as the Chief Operating Officer of the National Geospatial-Intelligence Agency (NGA), then later led the firm Noblis as its president. Ellen was then appointed the Assistant Secretary of State for Intelligence and Research (INR), where she led an organization famed for the highest quality of analysis in the US IC.

In the conversation, Bob and Ellen spoke highly of her time with the Coast Guard, including the agency’s formal entry into the intel community and the sophistication of the United States Coast Guard Cyber Command (CGCYBER).

With the context provided by this OODAcast conversation, we return to the joint Cybersecurity Advisory (CSA) released in late June by the Cybersecurity and Infrastructure Security Agency (CISA) and the United States Coast Guard Cyber Command (CGCYBER) “to warn network defenders that cyber threat actors, including state-sponsored advanced persistent threat (APT) actors, have continued to exploit CVE-2021-44228 (Log4Shell) in VMware Horizon® and Unified Access Gateway (UAG) servers to obtain initial access to organizations that did not apply available patches or workarounds.”

This CISA/CGCYBER collaboration caught our eye and we analyze how it compares to previous joint CSAs and is differentiated by CGCYBER’s unique brand of intelligence. This joint CSA also provided a context for an OODA Loop update on the ongoing Log4Shell threat of attacks and further evidence of the success of the CISA JCDC (as VMware and Secureworks are direct contributors to this joint CSA).
