Submission + - Backdoor Could Allow Company To Shut Down 70% Of All Bitcoin Mining Operations (bleepingcomputer.com)

An anonymous reader writes: An anonymous security researcher has published details on a vulnerability named "Antbleed," which the author claims is a remote backdoor affecting Bitcoin mining equipment sold by Bitmain, the largest vendor of crypto-currency mining hardware on the market. The backdoor code works by reporting mining equipment details to Bitmain servers, who can reply by instructing the customer's equipment to shut down.

Supposedly introduced as a crude DRM to control illegal equipment, the company forgot to tell anyone about it, and even ignored a user who reported it last fall. One of the Bitcoin Core developers claims that if such command would ever be sent, it could potentially brick the customer's device for good.

Bitmain is today's most popular seller of Bitcoin mining hardware, and its products account for 70% of the entire Bitcoin mining market. If someone hijack's the domain where this backdoor reports, he could be in the position to shut down Bitcoin mining operations all over the world, which are nothing more than the computations that verify Bitcoin transactions, effectively shutting down the entire Bitcoin ecosystem. Fortunately, there's a way to mitigate the backdoor's actions using local hosts files.

Submission + - Intel Puma6 modems highly vulnerable to DOS attack (dslreports.com)

Idisagree writes: It's being reported by users from the dslreports forum that the Puma6 Intel cable modem variants are highly susceptible to a very low bandwidth DOS attack.

To add to this there are class actions lawsuits already going forward for performance issues with the Puma6. (https://www.classactionlawyers.com/puma6/)

It would appear the atom chip was never going to live up to the task it was designed for and these issues may have been known within Intel for quite some time.

I wish those same right wing idiots would carry over their contempt for "experts" into every aspect of their lives...

Going to fly on an airplane? Forget a licensde pilot. Find the guy who agrees with you ideologically. What could go wrong?

Need a medical procedure done? Don't use one of those "liberal" doctors with a degree. Ask Joe the Plumber to do it for you. He knows more than those stupid doctors anyway!
