The ubiquity of ransomware continues, this time with The Guardian announcing they were partially shut down from an attack. Staff are working from home as the incident is being investigated and data is recovered. Publishing seems to be continuing, and the print paper ran as expected.
There have been a couple reports published recently on how ransomware and other malware is distributed, the first being a public service announcement from the FBI, detailing what might be a blindly obvious attack vector — search engine advertising.
