Risky Bulletin: Another Chinese security firm has its data leaked
Presented by

More than 12,000 internal documents were leaked online from Chinese security firm KnownSec.
The files were uploaded last week on GitHub by an unknown individual and later removed before the repo got any widespread circulation.
According to analyses from Mrxn and NetAskari, who got their hands on the leak, the most recent documents are from 2023. This suggests this was likely when the files were stolen/exfiltrated from the company's network, or at least someone intentionally truncated the leak to keep the most recent files for themselves.
