Another Special Report just sent, using Internet-wide scan data to detect vulnerable MS Exchange servers from @kryptoslogic (hat tip!). Blog provides a comparison of coverage between that and our previous Special Report: shadowserver.org/news/shadowser… Report: shadowserver.org/what-we-do/net…

With many un-patched MS #Exchange Servers still being rapidly compromised, we have partnered with @kryptoslogic to provide another Special Report covering 6720 exposed webshells that could be used to deploy ransomware, etc. Please remediate urgently! shadowserver.org/news/shadowser…

Over the next few days we'll be fine tuning our scanning and gathering more data - we think there's probably a bunch more based on other people's data but this is what we have tonight. 2/2

We've just loaded 60k~ IPs into Telltale (telltale.kryptoslogic.com) which we've found vulnerable to ProxyLogon/CVE 2021-26855 - this is being exploited in the wild - please patch and run Microsoft's MSERT tool to look for signs of compromise. We suspect there are more then 60k 1/2

We've just discovered 6970 exposed webshells which are publicly exposed and were placed by actors exploiting the Exchange vulnerability. These shells are being used to deploy ransomware. If you're signed up to Telltale (telltale.kryptoslogic.com) you can check you're not affected
