Internal SSD can be wiped with TRIM, but USB sticks are external SSD. They're apparently difficult to wipe securely enough to make forensic analysis of the device impossible. This question has been asked before, about 4 or 5 years ago and the information is probably outdated. Looking for up-to-date advice on how to securely wipe files on a USB from a bootable media.
Is it possible to have a setup that can securely wipe USB with TRIM? Anyone know of any programs that will securely shred files on USB, making them impossible to recover via forensic recovery software?
