Threats Tagged 'credential dumping'

An exposed open directory at a staging server revealed an active intrusion by operators linked to The Gentlemen ransomware group. The operation involved establishing persistent access through privileged account creation, credential theft via LSASS dumping, and lateral movement across a Windows domain. Attackers deployed multiple implants including EtherRAT, which retrieves command-and-control domains from an Ethereum smart contract, alongside Sliver and custom Go reverse shells. Lateral movement was achieved through remote scheduled tasks distributing MSI payloads, while security products were disabled and reverse tunnels established for persistent access. The infrastructure and tactics align with previously documented The Gentlemen campaigns, including a ClickFix operation deploying EtherRAT.

Since late 2025, government and diplomatic entities in Southeast Asia have been targeted by sophisticated attacks involving GoSerpent, a Go-based RAT with proxy capabilities. The malware receives encrypted arguments and deploys additional tools for data collection and credential dumping. GoSerpent has been active since 2021, with newer variants using AES-CBC encryption and ChaCha20 for communications. The campaign involves multiple stages: initial deployment of GoSerpent and ThumbcacheService to collect sensitive files, credential dumping via Mimikatz and QuarksDumpLocalHash, followed by deployment of Stowaway RAT in May 2026 and TmcLoader/TmcPayload for stealthy data exfiltration through network shares. The integrated toolset demonstrates sophisticated operational planning, with attackers leveraging Alibaba Cloud and UCLOUD HK infrastructure while exhibiting possible connections to the TetrisPhantom threat actor.

A previously unseen ransomware family named Spirals was deployed in a double extortion attack against an IT services company in South Asia in June 2026. The Rust-based payload demonstrated sophisticated capabilities including defense evasion, encryption, lateral movement, and privilege escalation. Attackers gained initial access through a compromised internet-facing IIS web server via an ASP.NET web shell, moving rapidly to deploy ransomware within 24 hours. They established persistence using multiple tunneling tools, disabled endpoint security, harvested credentials through SAM hive and LSASS dumps, and deployed reverse-SOCKS proxies for covert command-and-control. The ransomware was distributed across the network using PsExec, encrypting files with AES-128 keys and threatening data publication within six days. The skilled execution suggests potential for wider campaigns, though the threat actor remains unidentified.

In July 2025, threat actors compromised organizations through SEO poisoning campaigns targeting users searching for legitimate IT management tools. Users downloading trojanized installers for ManageEngine OpManager received Bumblebee malware, granting initial access. The attackers exploited the fact that users executing these IT tools were privileged administrators, enabling rapid lateral movement to domain controllers. They dumped credentials using wbadmin, created backdoor accounts with enterprise admin privileges, and installed RustDesk for persistent access. AdaptixC2 beacons were deployed for command and control. The threat actors conducted extensive reconnaissance, dumped LSASS memory across multiple systems, attempted Veeam credential theft, and exfiltrated data via SFTP using FileZilla. The intrusion culminated in Akira ransomware deployment across both root and child domains within 44 hours, with subsequent re-encryption two days later affecting the child domain.

A coordinated threat campaign has been identified leveraging SEO poisoning to distribute Bumblebee malware via trojanized installers of IT management tools. The campaign targets users searching for legitimate software like ManageEngine OpManager. Upon execution, Bumblebee establishes initial access, enabling lateral movement, credential dumping, deployment of remote access tools, and data exfiltration. The intrusions often end with the deployment of Akira ransomware, resulting in severe operational disruptions. Multiple organizations have been impacted, with various security teams reporting consistent patterns of compromise.
