For example, say the statute of limitations for 18 USC 1030 is two years. If a person hypothetically stole a scooter by hacking, two years later, they would be in the clear, right?
No. The discovery rule says that if a damaged party, for good reason, does not immediately discover their loss, the statutes of limitations is paused until they do.
Accordingly, if the scooter company read a post today about a hack that happened “a long time ago” and therein discovered their loss, the statute of limitations would begin to tick today and the hacker could be in legal jeopardy for two more years.
