AlienVault OTX Malware

The Dharma ransomware is a malware family known for encrypting victims' data to extort ransom payments. It primarily targets systems through the exploitation of external remote services (MITRE ATT&CK T1133) and the use of valid accounts (T1078), indicating that attackers often gain initial access by compromising legitimate credentials or leveraging exposed remote access protocols such as RDP. Once inside the network, Dharma employs scripting techniques (T1064) to automate its malicious activities, including file and directory discovery (T1083) and network share discovery (T1135), to identify valuable data and propagate across networked systems. The ransomware then encrypts data for impact (T1486), rendering files inaccessible and demanding payment for decryption keys. Despite its impactful behavior, the threat is currently assessed with a low severity rating, possibly due to limited exploitation in the wild or the availability of defensive measures. No patches are available for this ransomware, as it exploits access vectors rather than software vulnerabilities. Indicators of compromise are not provided, which may complicate detection efforts. The attack chain suggests that initial access is often gained through compromised credentials or exposed remote services, followed by lateral movement and encryption activities. The lack of known exploits in the wild and absence of a CVSS score indicate that while the ransomware is a known threat, its current operational impact may be limited or targeted.

Dharma Ransomware Event

Dharma ransomware is a variant of ransomware malware that encrypts victims' files and demands payment for decryption. It is part of the broader family of ransomware known as Dharma, which has been active since at least 2016 and is known for targeting Windows-based systems. The ransomware typically encrypts files using strong encryption algorithms, appends a unique extension to encrypted files, and drops ransom notes instructing victims on how to pay the ransom, often in cryptocurrency. The sample referenced here is categorized as low severity with limited technical details and no known exploits in the wild at the time of reporting (2019). Dharma ransomware variants have been distributed through phishing emails, Remote Desktop Protocol (RDP) brute force attacks, and exploit kits. The lack of affected versions and patch links suggests this is an OSINT sample rather than a newly discovered zero-day vulnerability. The threat level is moderate (3 out of an unspecified scale), with a 50% certainty rating, indicating some uncertainty about the sample's impact or prevalence. Overall, Dharma ransomware remains a persistent threat due to its evolving variants and continued targeting of vulnerable systems, especially those with exposed RDP services or weak security controls.

OSINT - New Bip Dharma Ransomware Variant Released

The Bip Dharma ransomware variant is a new iteration of the Dharma ransomware family, which is known for encrypting victims' files and demanding ransom payments for decryption keys. Dharma ransomware typically spreads through phishing emails, exploit kits, or unsecured Remote Desktop Protocol (RDP) connections. Once executed, it encrypts files on the infected system using strong encryption algorithms, rendering data inaccessible to the user. The ransomware then displays a ransom note demanding payment, often in cryptocurrency, to restore access. This variant, identified through OSINT sources and reported by CIRCL, does not have detailed technical indicators or affected versions listed, suggesting limited public technical analysis or detection signatures at the time of reporting. The threat level is marked as moderate (3 out of an unspecified scale), and no known exploits in the wild have been documented, indicating that while the ransomware is active, it may not be widely propagated or may be in early stages of distribution. The low severity rating assigned likely reflects limited impact or scope at the time of publication rather than the inherent danger of ransomware attacks. However, ransomware like Bip Dharma poses significant risks due to potential data loss, operational disruption, and financial costs associated with ransom payments and recovery efforts.

OSINT - New Arena Crysis Ransomware Variant Released

The Arena Crysis ransomware variant is a new iteration of the Dharma ransomware family, identified through open-source intelligence (OSINT) sources. Ransomware is a type of malware that encrypts victims' files and demands payment, typically in cryptocurrency, to restore access. This variant continues the trend of ransomware targeting organizations and individuals by encrypting data and demanding ransom for decryption keys. Although specific technical details about this variant are limited, it is known to operate similarly to other Dharma ransomware strains, which often spread through phishing emails, exploit kits, or compromised remote desktop protocol (RDP) services. The variant was first reported in August 2017, and while it has a low severity rating in the source, ransomware inherently poses significant risks due to its potential to disrupt operations and cause data loss. No known exploits in the wild have been reported for this variant, and no specific affected software versions or patches are available. The threat level and analysis scores suggest moderate concern but limited detailed intelligence. The lack of indicators and technical specifics limits the ability to perform deep forensic or detection rule development. However, the presence of this variant in the threat landscape underscores the ongoing risk ransomware poses to organizations worldwide.
