Sweeps DNS, endpoint network and proxy/firewall telemetry for BraZetsu C2, panel and shop domains using exact or subdomain matching. The apex installscenter.com remains active on Cloudflare with wildcard certificates.
Sweeps Defender XDR telemetry for known NEBULA / KNTRAT indicators (SHA256 hashes, C2 IP, decoy domain and URLs, burner publisher emails). Hash matching is scoped per table (execution hash only in process events), noisy tooling is excluded from command-line matches, network hits are limited to connection events, and results are aggregated per device and IOC.
Detects anomalous process execution and loopback network activity associated with the Model Context Protocol (MCP) 'exec_in_session' method. This pattern indicates an adversary potentially abusing the AI coding assistant's MCP server capabilities to execute arbitrary commands as a C2 channel.
Detects a node/npm/npx process writing to a Unix shell startup file (.zshrc, .zprofile, .bashrc, .bash_profile) immediately after package install activity. STARDUST CHOLLIMA (DPRK-nexus) used stolen maintainer credentials to compromise the Axios npm package and deliver platform-specific "ZshBucket" malware, and separately injected a malicious dependency into 131 Mastra AI framework packages. Malicious postinstall scripts modifying shell profiles is a persistence mechanism consistent with this campaign's naming and delivery pattern.
This analytic detects the usage of the Utility osascript on a macOS device initiated a network connection lasting longer than 10 minutes (600 seconds).
Adversaries may abuse osascript and AppleScript shell execution to establish long-lived command-and-control or remote connections.

Detects endpoint connections to known DarkSword/Coruna exploit-host and C2 infrastructure. The shared AWS IP is only matched on C2 ports 8881/8882 to reduce collateral hits.
Detects network, DNS, email, and URL click events matching known IOC domains associated with AdFection, Candiru, and Discover-Tech threat intelligence reports.
Detects indicators of compromise associated with malicious Firefox wallet-clone extensions (Rabby/OKX clones) by checking for known file hashes, extension file names in Firefox profile directories, and network connections to known C2 domains and workers.dev subdomains.
Detects a sequential pattern where a browser process (Chrome, Edge, or Safari) accesses an AI chat platform's conversation API, followed within 5 minutes by a network connection to a known unauthorized exfiltration destination (api.pbapi.xyz). This pattern suggests the potential use of a browser-based tool or extension (e.g., Poper Blocker or similar) to intercept and exfiltrate AI chat history.
Identifies execution of network share enumeration commands (smbutil, showmount) that can be leveraged by adversaries to discover accessible SMB and NFS resources, supporting internal reconnaissance and potential lateral movement.
Detects the first-ever observed network connection from a device to WhatsApp Web or Telegram Web within a 30-day lookback period. This behavior is used to identify potentially unauthorized companion-device linking to a user's messenger account, which could indicate credential theft or unauthorized access.
Detects indicators of compromise associated with malicious Firefox wallet-clone extensions (Rabby/OKX clones) by checking for known file hashes, extension file names in Firefox profile directories, and network connections to known C2 domains and workers.dev subdomains.
Detects network connections to known Indicators of Compromise (IOCs) associated with the TraderTraitor campaign, including trojanized Terraform providers (FLATROOF/ROOFDECK malware families) using specific domains and URL paths.

Hash matching is scoped per table (execution hash only in process events), noisy tooling is excluded from command-line matches, network hits are limited to connection events, and results are aggregated per device and IOC.

Detects high Ollama API request volumes from a single client in a short time window. A burst may indicate automated abuse or contribute to resource contention, but GIN access logs do not establish malicious intent or service impact; validate the client and workload against local usage baselines.
Identifies repeated Ollama inference requests with long response times on /api/generate, /api/chat, and /v1/chat/completions.
Long response time can result from model size, prompt length, host resources, or normal workload. GIN access logs do not include prompt content and cannot establish a prompt injection or jailbreak attempt, so use this as an exploratory performance signal.

Detects data leakage and exfiltration attempts targeting Ollama model metadata and configuration endpoints. Adversaries repeatedly query /api/show, /api/tags, and /api/v1/models to systematically extract sensitive model information including architecture details, fine-tuning parameters, system paths, Modelfile configurations, and proprietary customizations. Multiple inspection attempts within a 15-minute window indicate automated exfiltration of valuable intellectual property such as custom model configurations, system prompts, and internal model specifications. This activity represents unauthorized data disclosure that could enable competitive intelligence gathering, model replication, or preparation for advanced attacks against the AI infrastructure.
