They breached the company’s network, forcing Colonial to stop pipeline operations and eventually to pay a ransom of $5 Million.</p> <p style="text-align: justify;"><!--more-->After the Colonial Pipeline breach, as well as a number of other successful attacks earning them at least $90 Million, members of the DarkSide group supposedly went their separate ways. But once a malicious infrastructure, always a malicious infrastructure (in most cases anyway). ThreatSTOP is constantly monitoring DarkSide-related infrastructure, and our team has seen constant activity on DarkSide domains.</p> <p style="text-align: justify;">Earlier this month, we posted about <a href="/watch-out-for-darkside-ransomware-on-fotoeuropa.ro-and-catsdegree.com" rel="noopener" target="_blank">a wave of blocked communication attempts </a>between devices protected by ThreatSTOP and the domains fotoeuropa[.]ro and catsdegree[.]com. Since then, we saw more waves of traffic attempts from four other domains also related to DarkSide - lagrom[.]com, gosleepaddict[.]com, securebestapp20[.]com, kgtwiakkdooplnihvali[.]com. Between these six domains, we have seen an accumulated 16+ Million blocked connection attempts in our customer logs. All of these domains are active in our threat targets, which include aggregated threat intelligence from numerous sources.</p> <p style="text-align: justify;"><img src="https://info.threatstop.com/hubfs/darkside_domains.png" alt="darkside_domains - ransomware IOCs" width="2227" loading="lazy" style="width: 2227px;"></p> <p style="text-align: justify;"><em>Image: ThreatSTOP <a href="https://check-ioc.threatstop.com/" rel="noopener">CheckIOC</a></em></p> <p>&nbsp;</p> <p style="text-align: justify;">We recommend blocking all inbound AND outbound traffic to IOCs related to DarkSide (see list below). If the attackers somehow manage to breach your network don't let their malware exfiltrate your data. Blocking outbound traffic is a critical layer of defense against cyber attacks.</p> <p style="text-align: center; font-weight: bold;">DarkSide Infrastructure Domains</p> <table cellspacing="0" width="534" style="border-collapse: collapse;
