Rumor US Stock Market Closes Monday After Massive Worldwide Hack Attack by China

Dow component Microsoft Corp. (MSFT) could trade lower on Monday after a cybersecurity firm revealed at least 30,000 U.S. organizations, including local governments and small businesses, have been hacked by an aggressive Chinese cyber espionage unit. According to KrebsOnSecurity, the hack exploits “four newly-discovered flaws in Microsoft Exchange Server email software, and has seeded hundreds of thousands of victim organizations worldwide with tools that give the attackers total remote control over affected systems.”
