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 network, DNS, email, and URL click events matching known IOC domains associated with AdFection, Candiru, and Discover-Tech threat intelligence reports.
Detects inbound emails featuring Spanish government and COVID-19 themes in the subject or sender display name, which contain URLs pointing to domains resembling Amnesty International or various media organizations, indicating potential phishing or social engineering campaigns.

Detects historical network connections, URL clicks, browser launches, email URLs, and process command lines associated with Wazza phishkit infrastructure IOCs including boegl-krysl.eu, coppietersrecherche.eu, and beacon-surge-sync.workers.dev.
Detects HTTP requests and responses associated with the Wazza phishing kit, specifically targeting the /api/wazza-config endpoint and its wildcard routing configuration JSON responses.

Detects a suspicious two-stage browser activity sequence where a user accesses a Maze survey-builder lure (t.maze.co) followed by a navigation to a Cloudflare Workers subdomain hosting a spoofed Microsoft Authentication device-code phishing page. This pattern is indicative of a multi-stage phishing attack aimed at credential or device token theft.
This rule monitors network traffic for TLS SNI and HTTP URI indicators associated with known typo-squatted or spoofed Google Drive and Google Meet phishing domains. It also detects the download of a specific ZIP archive used as a phishing lure.

Detects emails from free-mail domains (@mail.com or @outlook.com) that contain a specific malicious infrastructure indicator in the InternetMessageId or originate from a known suspicious IP address associated with TA419-style spoofing campaigns. This indicates the email was relayed through unauthorized infrastructure rather than the expected legitimate mail providers.
Detects historical network connections, URL clicks, browser launches, email URLs, and process command lines associated with Wazza phishkit infrastructure IOCs including boegl-krysl.eu, coppietersrecherche.eu, and beacon-surge-sync.workers.dev.
Detects HTTP requests and responses associated with the Wazza phishing kit, specifically targeting the /api/wazza-config endpoint and its wildcard routing configuration JSON responses.
Detects outbound network connections (HTTPS/TLS) to known malicious domains used by TA419 for AitM (Adversary-in-the-Middle) phishing campaigns. These domains are identified as part of a spoofed OneDrive document/file sharing theme intended to steal user credentials.
Detects a multi-stage social engineering chain attributed to TA419. The activity begins with a benign trust-building email from specific domains or addresses, followed by a subsequent email to the same recipient containing a link to a known URL shortener or redirector, indicating a potential AitM phishing sequence.
This rule monitors for network and user interaction with known phishing domains that impersonate Microsoft, Outlook, or Teams services. It aggregates data from DNS queries, device network connections, inbound email URL links, and web URL click events to identify potential phishing attempts using a community-sourced watchlist from phishunt.io.
