Hackers Breach U.S. Agencies via Microsoft Server Flaw, Washington Post Reports

Hackers have exploited a previously unknown vulnerability in Microsoft server software to infiltrate several U.S. government agencies and private businesses in recent days, the Washington Post reported, citing state officials and independent security researchers. The scale of the breaches and the identities of the affected organizations were not disclosed, but investigators said the attacks were detected earlier this week. Both federal and private cybersecurity teams are working to identify the flaw, contain the intrusions and assess potential data loss. Microsoft had no immediate comment on the report, and it is unclear when a patch will be issued. The incident adds to growing concern over supply-chain and software vulnerabilities that can be leveraged against critical public- and private-sector networks.
