This rule detects network connections to a predefined list of known Microstealer malicious domains. These domains are often associated with malware command and control (C2) infrastructure, phishing, or other malicious activities. Monitoring connections to such domains can help identify compromised systems or active malware infections.
Correlates phishing email delivery with subsequent communication to attacker-controlled domains.
Detects incoming emails where a single URL contains indicators of two or more distinct security vendor rewriting services. This technique is used by adversaries to create multi-layered redirect chains to bypass automated scanners and deliver malicious content, as seen in Tycoon2FA and Sneaky2FA campaigns.
This rule detects the presence of MicroStealer malware by matching known MD5, SHA1, or SHA256 hashes of its binaries against file events on monitored devices. MicroStealer is a credential stealer that targets various applications to exfiltrate sensitive information.
Detects known malicious invoice PDFs and email samples used in Crimson Kingsnake campaigns.
This rule detects network connections to specific deep link patterns associated with messaging applications like Telegram, WhatsApp, and Signal. Such deep links can be used in phishing attempts or to initiate actions on a user's device through these applications.
This rule detects network connections to a specific Discord webhook URL and another suspicious domain (78smp.com/m/). This pattern is often associated with malware attempting to exfiltrate data or establish command and control (C2) via Discord webhooks, or other suspicious domains.
This rule detects the presence of files on endpoints that match a list of known malicious SHA256 hashes associated with the Nuso malware. It queries DeviceFileEvents to identify any file with a matching hash.
Detects the loading of 'hostfxr.dll' from suspicious user-specific AppData folders by 'CrossDeviceService.exe' or 'Teams.exe'. This behavior can indicate an attempt to load a malicious .NET runtime, potentially for DLL hijacking or code injection, often associated with persistence or execution techniques.
This rule detects network connections to specific IP addresses and ports (1259, 1269) via UDP, or the presence of a file with a specific SHA256 hash. This combination could indicate command and control (C2) communication or data exfiltration using a custom UDP protocol.
