RESTON, Va. (AP) — Cyber sleuths have already blamed China for a hack that exposed tens of thousands of servers running Microsoft’s Exchange email program to potential hacks. The CEO of a prominent cybersecurity firm says it now seems clear China also unleashed an indiscriminate, automated second wave of hacking that opened the way for ransomware and other cyberattacks.
The second wave, which began Feb. 26, is highly uncharacteristic of Beijing’s elite cyber spies and far exceeds the norms of espionage, said Kevin Mandia of FireEye. In its massive scale it diverges radically from the highly targeted nature of the original hack, which was detected in January.
“You never want to see a modern nation like China that has an offense capability — that they usually control with discipline — suddenly hit potentially a hundred thousand systems,” Mandia said Tuesday in an interview with The Associated Press.
Mandia said his company assesses based on the forensics that two groups of Chinese state-backed hackers — in an explosion of automated seeding — installed backdoors known as “web shells” on an as-yet undetermined number of systems. Experts fear a large number could easily be exploited for second-stage infections of ransomware by criminals, who also use automation to identify and infect targets.
