The digital miscreant known as ComodoHacker has claimed responsibility for the high-profile DigiNotar digital certificate authority hack.

Soon after the Comodo forged certificates hack an Iranian using the handle Comodohacker posted a series of messages via Pastebin account providing evidence that he carried out the attack. The account, which has been dormant since March, sprung back to life on Tuesday with claims that the individual or individuals behind it hacked DigiNotar as well, net security firm F-Secure reports.

The hacker boasted he still has access to four other (unnamed) "high-profile" CAs and retains the ability to issue new rogue certificates, including code signing certificates. The hacker (active on Twitter under the username ichsunx2) claimed that the domain administrator password of the DigiNotar network was Pr0d@dm1n.

Compromises against both Comodo affiliates and DigiNotar allowed hackers to generate bogus SSL certificates. The certificates create a means to mount convincing man-in-the-middle or phishing attacks. Evidence suggests that a rogue certificate issued in July under the name of Google as the result of the DigiNotar hack was used to spy on Iranian internet users.

The still-unfolding DigiNotar saga further underlines the fragility in the net's foundation of trust first highlighted by the Comodo hack. ®
