Sinclair TV Stations Taken Down in Ransomware Attack

REvil operation shuttered yet again, Wave of weekend cyberattacks on Israeli hospitals thwarted, $590 million in ransomware-related activity occurred during the first half of 2021, much more

Early yesterday, TV broadcasts for Sinclair-owned channels went down across the U.S. in a ransomware attack. The company says it implemented its incident response plan and took measures to contain the incident. However, Sinclair also says the attack may continue to cause “disruption to parts of the Company’s business, including certain aspects of its provision of local advertisements by its local broadcast stations on behalf of its customers.”

The attack took down the Sinclair internal corporate network, email servers, phone services, and the broadcasting systems of local TV stations. The attack's widespread nature stems from the fact that sections of the Sinclair IT network were interconnected through the same Active Directory domain, allowing the attackers to reach broadcasting systems for local TV stations. The attack follows a company-wide password reset for IT resources shared by local stations in July after what it described as a “potentially serious network security issue.” (Catalin Cimpanu / The Record)

Following an apparent hijacking of the gang’s domains, the REvil ransomware operation has likely shut down yet again.

Recorded Future's Dmitry Smilyanets says that an unknown person hijacked the Tor hidden services (onion domains) with the same private keys as REvil's Tor sites and likely has backups. The gang had earlier shut down in the face of international condemnation of the ransomware attack on Kaseya in July, but REvil revived itself again in September.

Missouri lawmaker Representative Ashley Aune, D-Kansas City, criticized Republican Governor Mike Parson for seeking to prosecute the St. Louis Post-Dispatch reporter who responsibly reported a flaw in a state website that exposed social security numbers of state school teachers, administrators, and counselors.

She also called on the governor to allow a cybersecurity panel to investigate the incident. Ashley said that instead of prosecuting a journalist, the governor should finally appoint members to the newly established Missouri Cybersecurity Commission, “something he has neglected to do since he signed the bill establishing it earlier this year.” (Jason Hancock / Missouri Independent)

In a significant move, the White House has an ambitious plan to reduce the risk of phishing to the U.S. government that calls for phasing out the use of SMS and app-based multi-factor authentication and replace them with phishing-resistant methods such as hardware security keys.

The effort is part of a broader push to move the federal government to zero trust architecture, as President Biden’s executive order spelled out last May. The move to zero trust will be a significant task for the Office of Management and Budget (OMB). OMB has recently published its zero trust strategy, which points to PIV [Personal Identity Verification] cards, as well as WebAuthn. This specification allows the use of hardware security keys to log into websites. (Joseph Cox / Motherboard)
