Detects network activity (DNS queries, HTTP Host headers, and TLS SNI) directed towards the known Blinder Tunnel staging domain 'asdfafadafg.online'. This behavior is indicative of command-and-control (C2) communication or initial staging of malicious payloads.
Detects DNS lookups, TLS connections, and network traffic associated with the PoeLLM cryptominer communicating with Kryptex mining pools, as well as Stratum mining protocol login attempts.

Detects DNS queries and TLS SNI traffic associated with known lookalike domains used by the threat actor TA419 for organization impersonation, which are commonly utilized in spearphishing campaigns.
Detects DNS queries, HTTP host headers, and TLS SNI traffic associated with known credential-phishing domains used by the threat actor TA419. The rule monitors for communication to a specific list of domains identified as malicious or used in phishing campaigns.

Detects network communication associated with SideCopy's ReverseRAT malware by monitoring for DNS lookups to a known malicious domain (dns.educationportals.biz) and outbound connections to a hardcoded C2 IP address (45.61.157.22).
Detects DNS queries for the domain 'docsportal.in', which is associated with the SideCopy threat group's HTA-staging activity for delivering the ReverseRAT malware.
Detects DNS queries and TLS SNI traffic associated with known lookalike domains used by the threat actor TA419 for organization impersonation, which are commonly utilized in spearphishing campaigns.
Detects DNS queries, HTTP host headers, and TLS SNI traffic associated with known credential-phishing domains used by the threat actor TA419. The rule monitors for communication to a specific list of domains identified as malicious or used in phishing campaigns.
Detects anomalous network behavior where a source host initiates a high volume of DNS TXT record queries to an external domain within a short timeframe. Such patterns are indicative of data exfiltration or C2 communication tunneling through DNS protocol.
This rule detects DNS queries for domains associated with DPRK-aligned threat actor backdoors, specifically identified in research as related to curlRAT or similar secondary-stage malware communication. Monitoring these domains can identify potential beaconing or C2 communication from compromised hosts.
Detects DNS tunneling attempts by identifying DNS queries with abnormally long subdomains (greater than 50 characters) that exhibit a high request rate (20 or more queries within 60 seconds). This behavior is characteristic of C2 communication tools such as iodine or dnscat2, which encode data within DNS query labels to bypass traditional network security controls.
