Another victory for hackers and a blow for the security of open source systems: OpenX, the online and mobile advertising company that announced a $22.5 million fund raising just last month, says that it is closing down its OnRamp open source ad serving platform, after the service was hacked on February 9, and the company determined that it would be too risky and costly to continue using it securely.
The news was announced by OpenX on its public forum this morning, along with a longer explanation for the decision.
