How to hack into Comcast’s ‘recombination dna’ technology

The FCC has been quietly rolling out a major update to its “recombiant dnas” to improve the speed of its network, including its ability to detect and block rogue dnas.

The FCC has announced the first major update since a December 2016 hack into the company’s “recompense dna” system that allowed Comcast to gain control of the network.

The dnas’ new code, which was released on Wednesday, will allow Comcast to use the new code to “reconfigure” the dnas to block new malicious devices.

“The Comcast reconfiguration dna software update will provide enhanced security for Comcast customers, and will allow them to manage their network better by ensuring that their dnas are properly configured,” a Comcast spokesperson told Ars Technica.

“The update also helps Comcast to better protect its customers by preventing the creation of rogue dna devices.”

As Ars Technic noted at the time, the Comcast recombinance dnas update was released months after the hack that let it gain control over the network, which made it possible for the network to be hijacked by malware that could cause data loss, compromise a computer, and even take over a router.

“It’s a nice way to show how Comcast has been improving network security, which they’re going to continue doing,” John Leech, a researcher with Kaspersky Lab, told Ars.

“It’ll be interesting to see how Comcast uses this new code.”

The FCC hasn’t specified which dnas Comcast is currently using to block rogue devices, but Ars Technics has obtained a list of all the dna codes that are currently in use.

Ars TechnIC also asked Comcast for a list and the dates on which they have updated their dna code, but a Comcast representative did not respond to our request for comment.

In a statement to Ars Technico, Comcast said it is “currently reviewing” the FCC’s update and will release a more detailed list of dna settings in the coming days.
