RESTON, VIRGINIA — The AP reports that investigators are blaming China for the hack in January that exposed thousands of servers running Microsoft's "Exchange" email program. <br /><br />The CEO of cybersecurity firm FireEye, Kevin Mandia, says it seems clear China has now also unleashed an indiscriminate second wave of hacking. <br /><br />The new hack builds on the January hack but strikes much wider. <br /><br />Mandia said: "You never want to see a modern nation like China, that has an offense capability — that they usually control with discipline — suddenly hit potentially a hundred thousand systems." <br /><br />The new attack started just days before Microsoft released a patch for the first attack. <br /><br />Mandia said: "They could sense it was going to end-of-life soon, so they just went wild. They machine-gun fired down the stretch." <br /><br />Another cyber sleuth said hackers were installing resource-demanding programs that "mine" cryptocurrencies on some "Exchange" servers that were hacked in January. <br /><br />The White House has called the overall hack an "active threat," but so far has not urged tough action against China.
