OSINT - Inside the Dragon: DragonForce Ransomware Group

The DragonForce ransomware group is a known threat actor specializing in ransomware attacks, leveraging a variety of sophisticated techniques to infiltrate and compromise targeted networks. This group employs multiple MITRE ATT&CK techniques, including the use of valid accounts (T1078) and domain accounts (T1078.002) to gain initial access and maintain persistence. They utilize PowerShell (T1059.001) for execution of malicious scripts, and establish persistence through registry run keys and startup folders (T1547.001) as well as Windows services (T1543.003). To evade detection and hinder forensic analysis, DragonForce clears Windows event logs (T1070.001) and extracts credentials from LSASS memory (T1003.001). The group conducts domain trust discovery (T1482), remote system discovery (T1018), system network configuration discovery (T1016), system information discovery (T1082), and file and directory discovery (T1083) to map the network environment and identify valuable targets. They also exploit remote desktop protocol (RDP) (T1021.001) and web protocols (T1071.001) for lateral movement and command and control communications. The final stage involves encrypting data for impact (T1486), effectively locking victims out of their systems and demanding ransom payments. Although no known exploits are currently reported in the wild for this group, their tactics indicate a high level of operational capability and adaptability. The threat level is assessed as moderate (3 out of an unspecified scale), but the overall severity is currently rated low by the source, possibly reflecting limited observed impact or activity at this time.

OSINT - #StopRansomware: Akira Ransomware

The Akira ransomware is a medium-severity threat identified through open-source intelligence (OSINT) and tracked by CIRCL under the #StopRansomware initiative. This ransomware employs multiple sophisticated attack techniques consistent with known ransomware behaviors, as mapped to MITRE ATT&CK patterns. Initial access vectors include spearphishing via attachments and links (T1566.001, T1566.002), exploitation of public-facing applications (T1190), and use of valid accounts (T1078). Post-compromise, Akira ransomware performs extensive reconnaissance activities such as system information discovery (T1082), network configuration discovery (T1016), domain trust discovery (T1482), process discovery (T1057), and enumeration of local and domain groups (T1069.001, T1069.002). Credential access techniques include harvesting credentials from LSASS memory (T1003.001) and from critical system files like /etc/passwd and /etc/shadow (T1003.008). The ransomware also manipulates domain accounts (T1136.002) and disables or modifies defensive tools (T1562.001) to evade detection. For lateral movement and persistence, it leverages remote access software (T1219) and connection proxies (T1090). Data exfiltration is conducted via alternative protocols (T1048) and cloud storage or cloud accounts (T1567.002, T1537). Finally, the ransomware encrypts data for impact (T1486) and inhibits system recovery mechanisms (T1490), effectively locking victims out of their data and demanding ransom. Although no known exploits are currently reported in the wild, the threat level is moderate, and the attack techniques indicate a well-rounded and potentially impactful ransomware campaign targeting both Europe and North America.

The threat campaign titled "Trickbot to Ryuk in Two Hours" describes a rapid attack chain leveraging the Trickbot malware to deploy Ryuk ransomware within a very short timeframe, approximately two hours. Trickbot is a modular banking Trojan that has evolved into a versatile malware platform used for credential theft, lateral movement, and network reconnaissance. In this campaign, Trickbot is used to gain initial access, perform extensive network and system discovery, credential dumping, and disable security tools to evade detection. The attack employs multiple MITRE ATT&CK techniques such as scheduled tasks (T1053) for persistence, disabling security tools (T1089), group policy modification (T1484), process injection (T1055), and obfuscated files or information (T1027) to maintain stealth and control. The adversaries leverage valid accounts (T1078) and credential dumping (T1003) to escalate privileges and move laterally across the network. Discovery techniques include system network connections (T1049), software and security software discovery (T1518, T1063), remote system discovery (T1018), and network share discovery (T1135). Remote services (T1021), remote desktop protocol (T1076), and remote file copy (T1105) facilitate lateral movement and payload deployment. The final stage involves deploying Ryuk ransomware, which encrypts data for impact (T1486), causing significant operational disruption. The campaign is known to utilize tools like Cobalt Strike and PowerView for post-exploitation activities. The rapid progression from initial compromise to ransomware deployment underscores the high operational tempo and sophistication of the threat actors behind this campaign.

The provided information describes a reconnaissance campaign involving an "Interesting Recon Script" identified by CIRCL under the kill-chain project. This campaign is characterized by the use of scripting techniques (MITRE ATT&CK T1064) executed via command-line interfaces (T1059) and requiring user execution (T1204). The script performs extensive discovery activities across multiple domains: account discovery (T1087), domain trust discovery (T1482), file and directory discovery (T1083), network share discovery (T1135), permission groups discovery (T1069), process discovery (T1057), registry queries (T1012), remote system discovery (T1018), software discovery (T1518), system information discovery (T1082), and system network connections discovery (T1049). These activities indicate a comprehensive reconnaissance phase aimed at gathering detailed information about the target environment, including user accounts, network topology, permissions, running processes, installed software, and system configurations. The campaign does not specify affected product versions, and no known exploits in the wild have been reported. The threat level is moderate (3), with a low severity rating assigned by the source. The attack requires user interaction to execute the script, which suggests it may be delivered via phishing or social engineering. The campaign's focus on discovery techniques aligns with early-stage intrusion activities, potentially preceding more impactful attacks such as lateral movement or data exfiltration.

Interesting Recon Script

Emotet is a sophisticated and modular malware strain primarily known for its use in large-scale spam campaigns and as a delivery mechanism for other malware families. The provided information details an Emotet campaign characterized by a variety of Tactics, Techniques, and Procedures (TTPs) aligned with the MITRE ATT&CK framework. Key techniques include spearphishing attachments (T1193) as the initial infection vector, leveraging malicious email attachments to compromise victims. Once executed, Emotet employs command-line interfaces (T1059), scheduled tasks (T1053), scripting (T1064), and Windows Management Instrumentation (WMI) (T1047) to maintain persistence and execute payloads. It also uses registry run keys and startup folders (T1060) to ensure execution upon system reboot. Process injection (T1055) is utilized to evade detection and maintain stealth by running malicious code within legitimate processes. Emotet conducts extensive reconnaissance activities such as account discovery (T1087), domain trust discovery (T1482), and system owner/user discovery (T1033) to map the environment and identify valuable targets. For command and control (C2) communication, it uses commonly used ports (T1043), standard application layer protocols (T1071), and standard cryptographic protocols (T1032) to blend in with normal network traffic and evade network defenses. The campaign also references tools like Empire and Cobalt Strike, which are often used post-compromise for lateral movement and privilege escalation. The threat level is medium, reflecting Emotet's widespread impact but also the availability of detection and mitigation strategies. No known exploits in the wild are indicated, but the campaign's persistence and modularity make it a continuing risk. Overall, this Emotet campaign demonstrates a multi-stage attack lifecycle from initial phishing to lateral movement and data exfiltration capabilities, leveraging a broad spectrum of Windows-based techniques to maintain stealth and persistence.
