Anonymous engineers claim BT gives spies backdoors to customer data

Carrier BT provides the British intelligence agency GCHQ and its American counterpart the NSA with direct access to customer data through the Internet modems it supplies, claims a 50-page document posted anonymously on the Cryptome site today.

The document, titled "Full  Disclosure: The Internet Dark Age," was originally post on Dec. 4 and reposted with updates a few days later. Its anonymous authors, calling themselves "The Adversaries," say they are engineers in a business that supplies small office and home office networking in the United Kingdom. The document they posted goes into extensive detail about their claim that modems supplied by BT have secret backdoors that can be used both to send outgoing customer data directly to the U.K. and NSA intelligence agencies, or even to give surveillance agencies a means to attack, should that be required.

BT spokesperson Kris Kozamchak, head of BT Global Services, would not comment on the contents of the document, but simply stated: "We comply with the law wherever we operate and do not disclose customer data in any jurisdiction unless legally required to do so."


Also on the security front at BT, Bruce Schneier, who has held the post of "security futurologist" at the company for about eight years, is leaving the telco at the end of December, according to a spokesman. Since the disclosures in June about the National Security Agency related to documents leaked to the media by former NSA contractor Edward Snowden, Schneier has been an outspoken opponent of the type of mass surveillance, backdoors and encryption weakening alleged to be done by the agency and its partners, which include GCHQ. Schneier's commentary about the NSA appeared frequently online.

Schneier could not immediately be reached for comment.
