Application Deletion

Without memory protection, it is trivial to create applications capable of deleting program code or database information. The Palm.Liberty.A Trojan horse, detected in August 2000 and claimed to be the first known Trojan for the Palm OS platform, did just this in erasing all databases on the device. With complete and unrestricted memory access, the malicious application simply iterates through the linked list of databases and unlinks each one as it proceeds.
