Impact of SKS keyserver poisoning on Gentoo
The SKS keyserver network has been a victim of certificate poisoning attack lately. The OpenPGP verification used for repository syncing is protected against the attack. However, our users can be affected when using GnuPG directly. In this post, we would like to shortly summarize what the attack is, what we did to protect Gentoo against it and what can you do to protect your system.
The certificate poisoning attack abuses three facts: that OpenPGP keys can contain unlimited number of signatures, that anyone can append signatures to any key and that there is no way to distinguish a legitimate signature from garbage. The attackers are appending a large number of garbage signatures to keys stored on SKS keyservers, causing them to become very large and cause severe performance issues in GnuPG clients that fetch them.
The attackers have poisoned the keys of a few high ranking OpenPGP people on the SKS keyservers, including one Gentoo developer. Furthermore, the current expectation is that the problem won’t be fixed any time soon, so it seems plausible that more keys may be affected in the future. We recommend users not to fetch or refresh keys from SKS keyserver network (this includes aliases such as keys.gnupg.net) for the time being. GnuPG upstream is already working on client-side countermeasures and they can be expected to enter Gentoo as soon as they are released.

Youtube's ban on "hacking techniques" threatens to shut down all of infosec Youtube
Youtube banning security disclosures doesn't make products more secure, nor will it prevent attackers from exploiting defects -- but it will mean that users will be the last to know that they've been trusting the wrong companies, and that developers will keep on making the same stupid mistakes...forever.

Chinese border guards reportedly install spy apps on tourists' Android phones
Border guards reportedly took tourists' phones and secretly installed an app on them which could extract emails, texts and contacts, along with information about the handset; basically a mother-load of privacy-sapping stuff.
There are reports that in some cases Android phones are returned to those entering the region with an app called Fēng cǎi installed. Apple's iPhones don't appear to come back with the app, but they could have been scanned by border control guards in a separate area after travellers were forced to hand them over.
