US Customs supervisor busted for stealing hardware from Homeland Security PCs

FBI arrested CBP supervisor Terry Liu for swapping CPUs, RAM and drives in 46 DHS computers and trading stolen parts via Newegg.

The FBI arrested and charged CBP supervisor Terry "Jiajia" Liu of Calais, Maine, with theft of government property after hidden cameras captured hardware swaps on midnight shifts. Investigators found 39 processors replaced, six memory modules swapped, and eight hard drives changed across 46 DHS computers at three Maine border facilities, with original Intel 14th-gen Raptor Lake Refresh chips downgraded to older, sometimes Pentium-class parts. Liu traded in the stolen Core i7 chips 16 times via Newegg's trade-in program over 14 months for roughly $200-210 each. Restoring the stolen hardware is estimated at $20,460, with full replacement around $105,800.

Tech support scams look different now. Here’s what to watch for

Malwarebytes warns tech support scammers now abuse sponsored search results, fake listings, calendar invites, and Apple Pay notifications, and shares red flags for impersonation scams.

Malwarebytes describes how tech support scams have expanded beyond browser locks and fake virus warnings to sponsored search results, hijacked on-site searches, fake platform listings, renewal scams, fake calendar invites, and Apple Pay notifications. Scammers impersonate trusted security companies including Malwarebytes, seeking payment, personal information, or remote access to victims' computers. Malwarebytes notes it does not outsource support, never makes unsolicited calls, and works with the FTC and the Global Anti-Scam Alliance to combat these scams.

New hardware device can RAM into encrypted memory, expose your data

Researchers built a $200 DDR5 interposer that silently drops memory writes to break TDX, SGX, and SEV-SNP confidential VM integrity, requiring physical access.

Researchers from KU Leuven, ETH Zurich, Durham University, and Google demonstrated DDRop, a hardware interposer costing under $200 that corrupts DDR5 bus commands to silently drop writes to encrypted memory, enabling replay attacks on confidential VMs. Because scalable memory encryption lacks freshness checks, protected VMs keep computing on stale attacker-selected data; on an Intel TDX server the attack forces debug mode for plaintext memory reads or forges attestation reports, succeeding in under two minutes without crashing. Intel and AMD both called the attack out of scope for their cloud threat models, with no mitigation planned, and proposed cache line versioning appears still vulnerable. The full interposer design is being released as open-source hardware.

Hackers Stole Flock’s Camera Software, Revealing How the Company Tracks Cars and People

Hackers who removed a Flock Safety license plate camera dumped its data, revealing person-detection capabilities and an encryption key stored unencrypted on the device.

A hacker collective calling itself stegan0gram physically removed a Flock Safety automatic license plate reader camera from a roadway, copied its storage, and shared the files with 404 Media, WIRED, and Distributed Denial of Secrets. Analysis found an encryption key in an unencrypted 'media' partition that unlocked videos of thousands of vehicle detections, with logs showing more than a million images generated in weeks. The software explicitly detects people, bicycles, and even bumper stickers, and records from one Georgia city were searchable by more than 2,000 agencies nationwide. The findings follow 2025 research by Jon Gaines documenting flaws enabling root-level access to Flock cameras.
