There's a Chinese proverb that roughly translates to "One chopstick is easily broken, but a bundle of chopsticks is unbreakable."
Multiple hacking groups in China previously thought to be individual actors are actually part of a larger, long-running, state-sponsored umbrella group, according to threat research group 401TRG at Denver-based security company ProtectWise.
The larger group, which 401TRG dubbed the Winnti umbrella, is an "advanced and potent threat" with a primary long-term mission that is politically focused, the researchers warn in a report released last week.
Winnti refers to a "custom backdoor used by groups under the umbrella," 401TRG said in its report.
Hacking activities are not uncharted waters for China.
According to a report earlier this year from security company Recorded Future, the Chinese government lied about belatedly informing the Chinese public of security flaws in order to hide exploits it was likely using in attacks.
