Hackers have continued to attract attention in these times, as they appear to have deployed new strategies to conduct their nefarious activities.
Cybersecurity firm Confiant has exposed the operation of a mysterious hacker group that breaks into ad servers with the sole intent of running malicious ads straight from the networks.
The hacker group found a flaw in old Revive ad servers that allows them to break into networks running on the server, Confiant reports. Once they gain access, they attach malicious code to existing ads and watch the ads roll out. Revive is an open-source ad serving system that has been in operation for well over a decade.
