Announcing the development through its public forum, OpenX said that because of the increased number of hacking attempts; the impossibility of continuing secure operations because of sophisticated and powerful intrusions that exploit open source software; the effect these may have on its customers, it has decided to close OnRamp service. The company has revealed that its other services like OpenX Enterprise and OpenX Market are going to continue to operate normally.

OpenX hasn’t made it clear what sort of information the hackers stole on the day of the hack nor has it revealed anything about the number of affected advertisers and publishers. As of now OnRamp interface is not available but OpenX has promised that it will be enabling the service at 5pm today so that its customers can “view the status of their accounts and copy relevant information needed in order to transition their ad serving to another provider.”

OnRamp will be terminated permanently on March 22 at 5:00 p.m. PST.
