There are also reports that the ongoing global pandemic has made infections like this easier, because operational staff may be working from home and that may broaden the attack surface. DarkSide also contains a killswitch if it detects a Russian language environment. We also see these 'affiliate' actors attempt a 'double extortion' where not only have they encrypted critical business data, they're also threatening to release it publicly if additional ransom is not paid. Is the DarkSide variant of ransomware more interesting than either of these? No, it isn't! However, there's significant worldwide interest because of the target chosen. Our Threat Research team also posted about detecting the Clop ransomware last month and recently updated further. One of the last significant ransomware events was the Ryuk ransomware at the end of October 2020, however our specialists pointed out that Ryuk wasn't particularly novel in terms of its operation.

Let's review that guidance, and update it where appropriate. Well, we're happy to find that the behavior of this ransomware isn't particularly novel, and all of the guidance we've shared for years on ransomware detection and mitigation applies.
Infact last year CISA released an alert about ransomware targeting pipeline operators so we know this is a big deal.
#SPLUNK SECURITY ESSENTIALS HOW TO#
Regardless of how all of this plays out, what Splunk customers want to know is how to detect and mitigate DarkSide ransomware, especially if they work in critical infrastructure. Colonial is hoping to get the pipeline back to operation by the end of this week. But until they can be sure that the adversary leveraging the DarkSide ransomware for the attack does not have the ability to affect operations, the pipeline will remain dry. Now, mind you, the ransomware did not directly cause the pipeline to shut down - rather, Colonial shut down operations voluntarily out of an abundance of caution. This 5500 mile pipeline transports about 45% of the East Coast's fuel supplies, and at the time of this blog, Colonial Pipeline had not returned to full operation. Late on Friday, May 7th, one of the US's largest gasoline pipelines was preemptively shut down by operator Colonial Pipeline, because their corporate computer networks were affected by Ransomware-as-a-Service authored and maintained by the group DarkSide.
