Update on Microsoft Actions Following Attack by Nation State Actor Midnight Blizzard
Today, CISA, the Federal Bureau of Investigation (FBI), and the Multi-State Information Sharing and Analysis Center (MS-ISAC) released a joint Cybersecurity Advisory (CSA), #StopRansomware: Phobos Ransomware, to disseminate known tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs), which are from incident response investigations tied to Phobos ransomware activity from as recently as February, 2024.
U.S. cybersecurity and intelligence agencies have warned of Phobos ransomware attacks targeting government and critical infrastructure entities, outlining the various tactics and techniques the threat actors have adopted to deploy the file-encrypting malware.
"Structured as a ransomware-as-a-service (RaaS) model, Phobos ransomware actors have targeted entities including municipal and county governments, emergency services, education, public healthcare, and critical infrastructure to successfully ransom several million in U.S. dollars," the government said.

A message posted to the website of the Blackcat hacking gang on Tuesday said it had been impounded "as part of a coordinated law enforcement action" by U.S. authorities and other law enforcement agencies. Among the logos of non-American agencies involved were those of Europol and Britain's National Crime Agency.

Hackers operating from Ukraine’s Main Intelligence Directorate (GUR) have claimed another scalp; the Russian Ministry of Defense (MoD).
The GUR, part of Kyiv’s Ministry of Defense, said a “special operation” enabled it to breach the servers of the Russian MoD (Minoborony) to obtain sensitive documents.
These included orders and reports apparently circulated among over 2000 structural units of the ministry.
