MPs Urge Must-Have Tech to End Alarming Phone Theft
As phone theft surges across the UK, MPs are pushing ministers and manufacturers to make stolen handsets economically worthless. They want the Home Secretary to compel Apple, Google, Samsung and others to combine secure boot, hardware IDs, remote lock/wipe and carrier blocks into a single, hard-to-defeat kill‑switch that protects victims and starves organised thieves.
MPs Urge Exclusive Affordable Tech to Halt Phone Theft
MPs are urging ministers to force Apple, Google and Samsung to deploy standardized, affordable tech that turns stolen phones into paperweights by blocking resets and reuse. Doing so could choke off criminals’ profits, slash street thefts and spare victims the pain of lost banking and identity access.
UEFI Secure Boot: Must-Have Best Practices for Arm64
UEFI Secure Boot promises stronger boot-time protections for Linux on Arm64, but a fragmented ecosystem of firmware, vendor keys and update practices has left adoption uneven.
