Search for Cobalt Strike Named Pipe Impersonation Norm_id=WinServer label="Process" label=CreateĬommand IN LogPoint customers can refer to our base sysmon configuration that covers various Cobalt Strike activities.Īdversaries commonly use Cobalt Strike’s named pipe impersonation feature to obtain SYSTEM privileges that can be detected via process creation events. Sysmon rules for Cobalt Strike Pipe Names If Sysmon is deployed in the environment and correctly configured, then it is an opportunity to detect Cobalt Strike’s default named pipes.
Before version 4.2, Cobalt Strike did not allow the operators to change the default naming scheme of named pipes. Named pipes are essential for the operation of Cobalt Strike beacons. Detecting Cobalt Strike activity in LogPoint LogPoint has now released UseCases v5.0.4, which includes alerts and a dashboard for Cobalt Strike to help you identify threats within your environment, so you can take corrective actions against them. Similarly, analysts can use default settings like beacon names and default certificates to help aid detection. Security analysts can create detections from the beacon’s leftover artifacts while performing post-exploitation. In September 2020, Cisco Talos reported that 66 percent of ransomware attacks involved Cobalt Strike and ransomware actors heavily rely on the tool as they abandon commodity trojans.Ĭobalt Strike’s post-exploitation features are exposed via beacons that are executed in the memory of the infected system. Several ransomware strains like Ryuk, Conti, Egregor and DoppelPaymer have started to use Cobalt Strike to speed up their ransomware deployment. APT29, APT32, APT41, Cobalt, FIN6, T A505, TIN WOODLAWN and Mustang Panda are just some of the threat actors who have used Cobalt Strike for their operations.Ĭobalt Strike was repeatedly used in the high-profile SolarWinds supply chain incident where the Raindrop loader dropped the Cobalt Strike payload. Proofpoint disclosed that they had attributed two-thirds of identified Cobalt Strike campaigns from 2016 through 2018 to well-resourced cybercrime organizations or APT groups.
In fact, two months before, Proofpoint had reported that adversarial use of Cobalt Strike increased 161 percent from 2019 to 2020 and still remains a high-volume threat in 2021.

Though the vendor screens the distribution of licenses to security professionals, adversaries were able to crack and leak it frequently. Malleable C2 is another beloved feature of Cobalt Strike that allows attackers to change how its beacons look and mimic other legitimate traffic to stay under the radar. Cobalt Strike’s post-exploitation suite includes support for keylogging, command execution, credential dumping, file transfer, port scanning, and more, making the adversary’s job easier. The beacons are stealthy due to in-memory execution via reflection into the memory of a process without affecting the file system.
In essence, Cobalt Strike is a modularized post-exploitation framework that uses covert channels to simulate a threat actor in the organization’s network.Ĭobalt Strike’s popularity is mainly due to its beacons being stealthy, stable, and highly customizable. Cobalt Strike, first released in 2012, is a commercial adversary simulation tool and is popular among red teams, pen-testers, and threat actors alike.
