Microsoft took the unusual step of warning that a computer bug it has now patched could be used by a cyber weapon similar to the WannaCry worm, which spread across the globe two years ago.

What's Affected?

It affects Windows 7 and Windows Server 2008 as well as Windows 2003 and Windows XP--older versions of Windows that Microsoft doesn't typically patch. Users of Windows 10 and Windows 8 aren't affected by the flaw.

KEY FACTS

--- It's one of several high-profile computer-security issues to emerge this week.

--- The impact isn't yet clear.Microsoft said that it believes it is "highly likely" the flaw will wind up being exploited by malicious software.

--- Microsoft said the best way for companies to protect themselves is to upgrade to newer versions of its software.

--- For WannaCry, Microsoft issued a patch months before the ransomware was a problem...

--- ...but it spread quickly and infected more than 200,000 systems world-wide.

Why This Matters

Microsoft's bug came a day after Facebook patched WhatsApp following the company's disclosure it had been used to install spyware on mobile phones by using a bug in the voice-calling feature. Intel also disclosed issues in its microprocessors that could allow hackers to gain unauthorised access to data stored in a computer's memory. The new bugs are similar to last year's Spectre and Meltdown flaws, but are hard to exploit and unlikely to cause the kind of widespread havoc of a computer worm, security researchers said.
