A sophisticated malware campaign targeting WordPress administrators has been discovered, utilizing a deceptive caching plugin to steal login credentials and compromise website security.
Commenting on this is Martin Jartelius, CISO at Outpost24:
“Installing an unknown plugin is always a risk. Markers such as the ones mentioned are also not great to use—a somewhat more engaged attacker would simply fork an open-source project, backdoor that, and include the expected information. The description associated with this “attack” shows both a lack of creativity and enthusiasm with the attacker. The reason we mention this is not to encourage the attackers to try harder, it’s to ensure that administrators are aware that malicious plugins are a real threat, and that they should never expect them to show up with this low level of ambition. Hackers are generally better than this. Think twice, install once.”
I am a WordPress user and I try to stick to known plugins to avoid this scenario. But because it pays to be paranoid, I will be giving my WordPress instance a second look to make sure that I don’t have anything “evil” lurking that I should be concerned about.
