The phrase is commonly applied to things like computer systems, financial accounts, and social media accounts, especially those from which personal data and/or money has been stolen. I really hope these strange charges on my bank statement don't mean that my account has been hacked. I bet that's some sort of scam to hack our Facebook accounts.

2. slang Irritated or annoyed. I'm really hacked about his constant attempts to undermine me to the boss.
