[Slashdot] - Up To 60,000 Computer Systems Exposed In Germany To Microsoft Flaw

Reuters reports: More than half of the vulnerabilities were addressed following a warning last weekend by the Federal Office for Information Security (BSI), but around 25,000 systems still need to be fixed, BSI chief Arne Schoenbohm said. "The warning has worked. In Germany, many Exchange servers have been secured by downloading patches," Schoenbohm said in written comments to Reuters. "Every vulnerable system is one too many and can lead to harm." In a 14-page report on the Microsoft vulnerability, the BSI said the behavior of hackers exploiting it had changed sharply since it was publicly revealed. Initially, most targets had been think tanks, universities, non-governmental organizations, law firms and defense companies - mostly in the United States. "Now, these exploits are being deployed at mass scale against thousands of targets - apparently worldwide," the report said. At least 10 different hacking groups were using the latest flaw in Microsoft's mail server software to break into targets around the world, according to researchers at cybersecurity company ESET. In Germany, two federal authorities have been affected by the hack, the BSI said, declining to say which.
