Newer threats from Microsoft against Unpatched Networks

Microsoft has detected and blocked a "new family of ransomware" that was being used against servers that still had not patched vulnerabilities after the attack on its Exchange Server software. The attack has claimed at least 60,000 victims globally. The updates it released on Friday are a temporary measure to defend against attacks, which were already occurring in many places, the company said.

 

BitSight Technologies, a Boston-based cybersecurity firm, said that based on internet-wide scans it had done this week nearly one-third of vulnerable Microsoft Exchange customers have yet to patch their systems. Those customers would are now also vulnerable to the new ransomware attacks until those patches are installed.

 

Hackers are using the weaknesses introduced in the original attacks, including secret entry points inserted in victims’ systems, to gain access. Governments have been hounding businesses to install the patches -- the Australian government has issued at least three warnings in nine days -- and Microsoft has warned organizations to take urgent action to forestall damage.

 

This latest update “means that Microsoft is concerned that people haven’t patched,” said Robert Potter, a cybersecurity expert based in Canberra, Australia. “If you’ve already been hit there’s very little you can do. You better hope your backups work, because you’re not going to get decrypted.
