TeamTNT is a financially motivated cybercrime threat actor best known for opportunistic attacks against Linux and cloud environments, especially exposed or misconfigured Docker, Kubernetes, and related cloud services. The group has been widely associated with cryptojacking operations, credential harvesting, and persistent backdoor deployment on compromised infrastructure. TeamTNT has also abused container ecosystems by publishing backdoored Docker images to public registries to facilitate follow-on compromise. The actor’s tradecraft centers on cloud-native and Linux-focused intrusion activity. Documented behavior includes targeting exposed Docker API services and unauthenticated JupyterLab instances, launching containers on compromised hosts, and using those footholds to scan for additional victims and propagate laterally across reachable infrastructure. TeamTNT has deployed cryptocurrency miners and backdoors, including use of Tsunami malware, and has used tools such as tmate to maintain covert remote access to compromised Linux servers. The group has also harvested cloud credentials, including searching process environments for AWS-related secrets. Observed post-compromise behavior includes extensive host and environment discovery, such as enumerating system version, architecture, disk partitions, logical volumes, hostname information, attached VGA devices, local IP addressing, and installed security products. TeamTNT commonly relies on shell scripting and native utilities, using tools such as curl and wget for payload retrieval and credential transmission over HTTP, and Base64 decoding within scripts to stage or execute additional components. The group has also established persistence through mechanisms including startup-folder scripts and service-based miner installation. Known aliases in the supplied data are limited to TeamTNT. The actor is primarily tracked as a cloud-focused cryptomining and credential-theft operation rather than a state-sponsored intrusion set.

This detection identifies instances where Windows Explorer.exe spawns PowerShell or cmd.exe processes, particularly focusing on executions initiated by LNK files. This behavior is associated with the ZDI-CAN-25373 Windows shortcut zero-day vulnerability, where specially crafted LNK files are used to trigger malicious code execution through cmd.exe or powershell.exe. This technique has been actively exploited by multiple APT groups in targeted attacks through both HTTP and SMB delivery methods.
This analytic identifies potential exploitation attempts of ProxyShell (CVE-2021-34473, CVE-2021-34523, CVE-2021-31207) and ProxyNotShell (CVE-2022-41040, CVE-2022-41082) vulnerabilities in Microsoft Exchange Server.

The following analytic detects attempts to exploit CVE-2022-26134, an unauthenticated remote code execution vulnerability in Confluence... This activity is significant as it allows attackers to execute arbitrary code on the Confluence server without authentication, potentially leading to full system compromise.
