The sample files compared are 99% similar in their entirety. (For example, several samples were observed being dropped by Smoke Bot, a loader that is developed by an adversary tracked as SMOKY SPIDER by CrowdStrike Intelligence.)Ĭode comparison of these Dharma samples rendered a 100% match of the functions in all analyzed samples. CrowdStrike ® Intelligence analyzed Dharma variants from multiple sources, including BGH incidents tracked by the OverWatch team as well as separately identified Dharma samples.

Separately, while the Phobos ransomware is likely to have been inspired by Dharma, the codebase of Phobos appears separate from Dharma.Īlthough Dharma is not centrally controlled - in contrast to major RaaS families, such as REvil, which is operated by PINCHY SPIDER - the code has not been forked or meaningfully altered across distribution channels.
Since this threat actor’s departure, Dharma has been marketed and sold by multiple, apparently independent actors, two of which were active in 2019 - and at least one remains active as of January 2020. Background: Dharma Status and Code Similarity Across VariantsĬrowdStrike identified that the original author of Dharma released the source code in 2016 before ceasing activity. These intrusions have exhibited consistent techniques that include gaining initial access over Remote Desktop Protocol (RDP) brute forcing or password spraying, using publicly available utilities to attempt to identify and uninstall security software, harvesting credentials, and mapping network shares. Victims have been identified in the following sectors: Dharma affiliates do not appear to discriminate among industries.

Throughout 2019 and into 2020, the CrowdStrikes Falcon OverWatch™ and Intelligence teams have identified ongoing attempts by criminal actors to install Dharma ransomware across a diverse range of organizations worldwide.ĭharma has been in operation since 2016 under a ransomware-as-a-service (RaaS) model, where developers license or sell ransomware to other criminals who then carry out an attack using the malware. One example is a series of BGH intrusions where criminal actors used common tactics to deploy Dharma ransomware.
However, BGH is not exclusive to sophisticated adversaries deploying advanced malware. These BGH campaigns have netted millions of dollars (USD) for major criminal actors like WIZARD SPIDER and INDRIK SPIDER.
Since at least 2018, criminal actors have been conducting big game hunting (BGH) campaigns, deploying ransomware on a targeted scale against large corporations or governments in pursuit of lucrative payouts.
