> Absolute Home & Office (originally known as CompuTrace, and LoJack for Laptops) is a proprietary laptop theft recovery software (laptop tracking software). The persistent security features are built into the firmware of devices. Absolute Home & Office has services of an investigations and recovery team who partners with law enforcement agencies to return laptops to their owners. Absolute Software licensed the name LoJack from the vehicle recovery service LoJack in 2005.
There used to be a BIOS option for on/off and "Permanently Disable", but that might have changed in recent versions.
Apple x86 laptops: shipped an Arm microcontroller (T2 Security Enclave) to assert control of interactions between x86 CPU and disk storage, until they could replace the CPU with Apple Silicon.
> CompuTrace has been shipped by every major x86 PC OEM for decades
UEFI-enabled "ARM PC" laptops are new for 2024 with ex-Apple Qualcomm/Nuvia/Oryon. Prior Arm-based devices did not provide UEFI runtime services for persistent manipulation of host operating systems. Windows 11 for Arm PCs was just released in November 2024.
x86 PC platforms provide decades of history to compare OEM anti-theft policies.
I had it in Lenovo X61 Tablet. It was called CompuTrace back then. It was a BIOS module that Windows executes while processing ACPI tables during boot. Now it's probably a UEFI module that does the same.
I removed it by 0-ing out the module in a BIOS update image and reinstalling Windows. This method probably doesn't work with UEFI anymore because it invalidates the signature, so yes, it's unremovable.
It seems like an absolutely terrible idea for a campaign "hey everyone - our company has been wildly successful at putting spyware on hundreds of millions of machines and no one even knows our name!"
It sounds like a major part of their plan, to just behave as a silent process that can always be re-booted through whatever changes the device goes through. Best to keep that sort of thing obscure.
It's been around for decades, the option to enable/disable it is in the BIOS setup on every machine that has it, and computer manufacturer's documentation tells you exactly what it is, because it's a selling point.
