Honeypots are devices with known vulnerabilities exposed on the Internet to lure attackers and monitor their activities. Hutchins&#8217; honeypots, though, did not appear to become encrypted, and the attack he witnessed was believed to be a failed campaign.<\/p>\n\n\n\n<p class=\"has-black-color has-pale-cyan-blue-background-color has-text-color has-background\"><strong><a href=\"https:\/\/www.bleepingcomputer.com\/news\/security\/microsoft-exchange-servers-now-targeted-by-blackkingdom-ransomware\/\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/www.bleepingcomputer.com\/news\/security\/microsoft-exchange-servers-now-targeted-by-blackkingdom-ransomware\/<\/a><\/strong><\/p>\n<div id=\"apvno-1067153749\" class=\"apvno-after apvno-entity-placement\"><script>\r\n_adsys_id = 33949;\r\n_adsys_size = 1;\r\n<\/script>\r\n<script src=\"https:\/\/d.wedosas.net\/d.js\"><\/script>    \r\n<\/br>\r\n<div>\r\n<script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js\"><\/script>\r\n<!-- AD-4 -->\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:inline-block;width:970px;height:250px\"\r\n     data-ad-client=\"ca-pub-7003427967427457\"\r\n     data-ad-slot=\"6272152047\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><\/div>\r\n<a href=\"https:\/\/affiliates.ssl.com\/820-3-1-13.html\" target=\"_blank\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" style=\"border:0px\" src=\"https:\/\/i0.wp.com\/affiliates.ssl.com\/media\/banners\/SSL-banner-UC-certificate-2-v5.png?resize=640%2C79&#038;ssl=1\" width=\"640\" height=\"79\" alt=\"Microsoft Exchange SAN UCC SSL\"><\/a><\/div>","protected":false},"excerpt":{"rendered":"<p>Another ransomware operation known as &#8216;BlackKingdom&#8217; is exploiting the Microsoft Exchange Server ProxyLogon vulnerabilities\u00a0to encrypt servers.
