Yet another official reseller of SSL certificate authority Comodo has suffered a security breach that allowed attackers to gain unauthorized access to data.
Brazil-based ComodoBR is at least the fourth Comodo partner to be compromised this year. In March, the servers of a separate registration authority were hacked by attackers who used their access to forge counterfeit certificates signed with Comodo's root signing key. Comodo admitted that two more of its resellers were hit in similar attacks, although no keys were issued.
Comodo has so far declined to name the resellers.
The
SQL-injection attack on ComodoBR exploited vulnerabilities in the company's web applications that allowed the hackers to pass database commands to the website's backend server. The attackers posted two data files that appeared to show
information related to certificate signing requests,
in addition to email addresses, user IDs, and password information for a limited number of employees.
Comodo president and CEO, Melih Abdulhayoglu, said Comodo systems were never compromised. He also said no certificates were issued as a result of the breach, and that the reseller had no access to Comodo databases.
