  • When you normally delete a file, it doesn’t actually delete it, to save time it just marks the space as free, so any new files can be written into that part of your drive.

    But the actual data just remains there until a new file is written to the storage.

    SecureErase does the second part without making an actual file.

    Normal delete:

    File: 01010101 -> no file:01010101

    Secure erase:

    File: 01010101 -> no file:00000000

    Oh yeah, definitely but those tend to be different attacks than would target random consumer computers.

    Being open source definitely plays a role in Linux security, but it’s minor compared to stuff like market share, user privilege, package management vs just installing random exes, different distros using different packaging systems.



  • There’s the Intel management engine and the amd platform security processor. Both manage low level tasks like booting, and have access to network data. Amds psp is known to have unrestricted access to user memory.

    There have been security vulnerabilities that would grant access to sensitive data exploiting both systems if not patched.

    As for a backdoor, there’s no evidence but I wouldn’t be surprised. The NSA has programs to insert backdoors into consumer products and these seem like the perfect place to do it. But again, there’s no evidence either chip is part of these programs.
