Explaining Efail and Why It Isn’t the End of Email Privacy

Last week the PGPocalipse was all over the news… Except that, well, it wasn’t an apocalypse.

A team of researchers published a paper(PDF) where they describe how to decrypt a PGP encrypted email via a targeted attack. The research itself is pretty well documented and, from a security researcher perspective, it’s a good paper to read, especially the cryptography parts.

But we here at Hackaday were skeptical about media claims that Efail had broken PGP. Some media reports went as far as recommending everyone turn off PGP encryption on all email clients., but they weren’t able to back this recommendation …read more

Another Defeat of the Intel Management Engine

If you have a computer with an Intel processor that’s newer than about 2007, odds are high that it also contains a mystery software package known as the Intel Management Engine (ME). The ME has complete access to the computer below the operating system and can access a network, the computer’s memory, and many other parts of the computer even when the computer is powered down. If you’re thinking that this seems like an incredible security vulnerability then you’re not alone, and a team at Black Hat Europe 2017 has demonstrated yet another flaw in this black box (PDF), allowing …read more

Radio Controlled Pacemakers Are Easily Hacked

Doctors use RF signals to adjust pacemakers so that instead of slicing a patient open, they can change the pacemakers parameters which in turn avoids unnecessary surgery. A study on security weaknesses of pacemakers (highlights) or full Report (PDF) has found that pacemakers from the main manufacturers contain security vulnerabilities that make it possible for the devices to be adjusted by anyone with a programmer and proximity. Of course, it shouldn’t be possible for anyone other than medical professionals to acquire a pacemaker programmer. The authors bought their examples on eBay.

They discovered over 8,000 known vulnerabilities in third-party libraries …read more

Yet Another IoT Botnet

[TrendMicro] are reporting that yet another IoT botnet is emerging. This new botnet had been dubbed Persirai and targets IP cameras. Most of the victims don’t even realize their camera has access to the Internet 24/7 in the first place.

Trend Micro, have found 1,000 IP cameras of different models that have been exploited by Persirai so far. There are at least another 120,000 IP cameras that the botnet could attack using the same method. The problem starts with the IP cameras exposing themselves by default on TCP Port 81 as a web server — never a great idea.

Most …read more
