Operation Winter SHIELD has ended, but the real impact is just beginning. Over the past 60 days, #FBI field offices conducted more than 600 engagements across 14 critical sectors. All field offices participated in #OWS – helping businesses, hospitals, utilities, schools, and local governments nationwide build #cyber resilience and respond effectively to every attack. As Jarrod Forgues Schlenker of FBI Cyber explains in an interview with the Microsoft Threat Intelligence podcast, Operation Winter SHIELD is about turning awareness into action.

Our prep

@arianevans @HackingDave

NightBeacon AI today identified an insanely cool phishing email attack that showed up on GTI/other sources as benign/non malicious. How it worked: NightBeacon determined the tonality was creating urgency (key indication of social engineering), it looks for any URLs, it went to the URLs, analyzed the pages and context, it checked SPF/DKIM/etc, as well as when the sites were registered. It's analysis: 100% confidence in phishing due to the method and actions they were taking, the newly formed phishing website, and other indicators. It additionally automatically went into customer system, generated dynamic KQL queries, and looked for any other users impacted by this, and if any of them actually clicked the link. Sent that all back to the analyst in under 10 seconds will a full writeup as well as recommended playbooks to execute post incident or automatically remove the emails from user inboxes. We have something special here that is leads ahead in the market for the MDR market. Incredible. binarydefense.com/nightbeacon Below is an example of writeups, playbook generations, and AI assistant that you can ask it questions about that specific alarm. Kick off agentic workflow (its done automatically when an investigation is opened), as well as help you generate queries based on technology platform. Insanely powerful. #BinaryDefense

Looking forward to the tabletop exercise

@FBIDirectorKash Unplugged Messenger. Secure and reliable. Available in Apple store or at Unplugged.com

FBI will continue publishing recommendations and asking all Americans to take preventive steps to protect their data even on encrypted commercial messaging apps - as we have seen evidence of foreign adversaries targeting their information through phishing schemes. This is part of the Trump administration’s most comprehensive Cybersecurity initiative in history - staying ahead of the constantly changing threat landscape.
