September 12, 2011, 2:11 PM — The CEO of a certificate-issuing company that was hacked in March is even more certain now that a wave of attacks against similar firms is backed by the Iranian government.
"I think even more so now than before," said Melih Abdulhayoglu, the CEO and founder of Comodo, a Jersey City, N.J.-based security company that is also one of hundreds of certificate authorities, or CAs, allowed to issue SSL (secure socket layer) certificates.
The certificates authenticate the identity of websites, to show, say, that Google is really Google.
Last March, after Comodo confirmed that its network had been breached and nine certificates stolen -- including ones for Google, Microsoft and Yahoo -- Abdulhayoglu said he believed the attacks came were backed by the Iranian government.
"We believe these are politically motivated, state driven/funded attacks," Abdulhayoglu said at the time.
The newest attack, conducted against DigiNotar, a Dutch CA, only strengthened Abdulhayoglu's belief that Iranian authorities were involved.
"We just witnessed the biggest man-in-the-middle attack in history," said Abdulhayoglu, talking about the fallout after one or more hackers broke into a Dutch CA's network in June, then stole more than 500 digital certificates.
DigiNotar, based in the Netherlands but owned by U.S. firm Vasco, admitted on Aug. 30 that its servers were compromised weeks earlier by unknown attackers.
A fraudulently-acquired certificate for google.com was used to spy on 300,000 Iranians , according to a forensics firm hired by the Dutch government to investigate the intrusion of DigiNotar's servers. Because Google has warned Iranians to reset their Gmail passwords, the assumption is that the fake certificate was used to monitor email within Iran.
Someone who calls himself "Comodohacker" and says he is a 21-year-old Iranian, has claimed credit for both the attack against DigiNotar and the earlier breach of Comodo. He has also declared he hacked four other CAs, including GlobalSign.
In statements he has published on the Web and in an email exchange to the New York Times, Comodohacker has asserted he acted alone . However, he has acknowledged he "shared some cert[ificate]s with some people in Iran."
