The Wordfence blog has an examination of an emerging attack on the Wordpress ecosystem.
[...] In the software industry, a supply chain attack exploits a trusted relationship between software vendors or authors and their customers. For WordPress, that means figuring out how to embed malware into software updates. In one case, we saw an existing plugin author install malware on customer sites in an effort to monetize an existing plugin. In every other case we have uncovered, the attack was carried out by someone who had purchased the plugin with the express intention of attacking its users.
This is a follow-up to December's discovery of backdoor code in three mildly popular plug-ins. Those otherwise-trusted plug-ins had been purchased from the original developer by a third party, who then injected malicious code in subsequent updates.
In the last two weeks, the WordPress.org repository has closed three plugins because they contained content-injection backdoors. ... Each of them had been purchased in the previous six months as part of the same supply chain attack, with the goal of injecting SEO spam into the sites running the plugins.

The Lego blocks fly behind you and phase right through your pants as if your pants aren't solid and then they crash directly into your raw snappyhole. It tickles! It tickles so bad! But it doesn't stop there. The Lego blocks begin spinning around on your asshole while pressing against it, and in doing so, they inflict excruciating tickle upon it! Eventually, the blocks break into your asshole and begin colliding with the sides of the deepest reaches of your ass, inflicting horrible tickle upon it all the while! Then, the toy clown begins rapidly shooting these Lego blocks into your ass while laughing at your suffering. No matter how much you scream for him to stop, his soft laughter continues...
Usually when this happens, the first thing I check is the good/evil toggle. Just about every time the thing has been set to evil. Fortunately they're RFC3514 compliant. If that doesn't work, find the Turtle of enormous girth and schedule a ritual of Chüd. Problem solved.
