Zero-day exploit completely defeats default Windows 11 BitLocker protections
A zero-day exploit circulating online allows people with physical access to a Windows 11 system to bypass default BitLocker protections and gain complete access to an encrypted drive within seconds. The exploit, named YellowKey, was published earlier this week by a researcher who goes by the alias Nightmare-Eclipse. It reliably bypasses default Windows 11 deployments of BitLocker, the full-volume encryption protection Microsoft provides to make disk contents off-limits to anyone without the key. READ MORE...

Fired hacker twins forget to end Teams recording, capture own crimes
Perhaps you remember Muneeb and Sohaib Akhter, the 34-year-old twin brothers we profiled earlier this week. Although they had the tech chops to commit years of petty crimes (like stealing airline miles), what landed them in truly serious trouble was deleting 96 US government databases in the hour after both were fired last year by the same federal IT contractor, Opexus. (Opexus had just found out that both brothers had previously been in prison for cyberfraud.) READ MORE...

Taiwan Incident Highlights Cybersecurity Gaps in Rail Systems
The communications and monitoring platforms for rail networks has come under scrutiny following the recent "hacking" of a Taiwanese railway operators' radio system, which led to the emergency stoppage of three high-speed bullet trains for nearly an hour. On April 5, a 23-year-old train enthusiast used a software-defined radio set up and hardware bought online to spoof a general alarm, or GA, alert to the operations center of Taiwan High Speed Rail (THSR).
