"Anyone inside Iran with problems, from fake Green Movement to all MKO members and two-faced terrorists, should [be] afraid of me personally," said ComodoHacker. "I won't let anyone inside Iran, harm people of Iran, harm my country's Nuclear Scientists, harm my Leader (which nobody can), harm my President."

MKO, or the "People's Mujahedin of Iran," is an Islamic group that advocates the overthrow of the current government of Iran.

"As I live, you don't have privacy in internet, you don't have security in digital world, just wait and see," ComodoHacker said.

Comodo was not available Sunday for comment on ComodoHacker's claims.
