Cybersecurity firm FireEye today released a report on a Russian cyberespionage group, which successfully breached a U.S. firm’s network and (the report argues) has Kremlin backing. The Journal has a summary of the report. Meanwhile, a coalition of cybersecurity researchers led by Novetta Solutions today published a report on a Chinese cyberespionage ring — which the researchers call Axiom — that appears to have Chinese government sponsorship. The Washington Post summarized this report.
