OpenBSD’s Theo de Raadt has received an email in which it was revealed to him that ten years ago, the FBI paid several open source developers to implement hidden backdoors in OpenBSD’s IPSEC stack. De Raadt decided to publish the email for all to see, so that the code in question can be reviewed. De Raadt received the email from Gregory Perry:
My NDA with the FBI has recently expired, and I wanted to make you aware of the fact that the FBI implemented a number of backdoors and side channel key leaking mechanisms into the OCF, for the express purpose of monitoring the site to site VPN encryption system implemented by EOUSA, the parent organization to the FBI,” Perry details in the email, “Jason Wright and several other developers were responsible for those backdoors, and you would be well advised to review any and all code commits by Wright as well as the other developers he worked with originating from NETSEC.
If this turns out to be true, you could wonder what else has been put in open source projects.
