Adversaries may attach filters to a network socket to monitor then activate backdoors used for persistence or command and control.
a13e DCV does not yet ship a13e-curated detection rules for T1205.002. The page is descriptive: it covers what the technique is, which platforms attackers exercise it on, and where the upstream Sigma community has rules you can translate via CloudSigma. As CloudSigma's corpus extends to this technique, the page lights up with embedded rules automatically — no manual update required.
T1205.002 sits inside MITRE ATT&CK's enterprise matrix; adversaries reach it via initial access or credential-access steps and pivot from it into impact, lateral movement, or persistence. Cloud blueprints — AWS CloudTrail, Azure Sign-in, GCP Audit Logs — are the high-fidelity observation surfaces where T1205.002 most reliably surfaces in production. DCV maps each cloud-native finding type to the technique so an a13e coverage scan tells you whether your existing detection controls cover T1205.002 before an adversary exercises it.
DCV does not currently ship a cloud-audit-log finding mapped directly to T1205.002. The technique earns a library page because a13e research cites it. Detection sits downstream, on the exploitation step the technique enables.
CloudSigma does not currently ship a stand-alone rule that fires on T1205.002 in isolation. Generate a starting-point rule from the CVE, vulnerability disclosure, or threat-research blog post that exercises this technique, then pair it with SIEM-side correlation before enabling in production.
High-fidelity detection of T1205.002 requires correlation
across multiple events. For example, a credential-validation call
followed by a reconnaissance chain (List* /
Describe*) within a short window from an unfamiliar
source. A single-event Sigma rule on
GetCallerIdentity alone fires constantly on
legitimate CLI, SDK and CI/CD activity.
Where you have a specific advisory, vulnerability disclosure or blog post that exercises T1205.002-style abuse, CloudSigma can generate a starting-point rule from that input. You then deploy it in your SIEM and combine it with the SIEM's native correlation features (timeframe joins across users, source-IP anomalies, impossible-travel checks). For T1205.002 specifically the generated rule is rarely sufficient on its own; pair it with the SIEM-side correlation logic before enabling in production.
Adversaries may attach filters to a network socket to monitor then activate backdoors used for persistence or command and control. With elevated permissions, adversaries can use features such as the `libpcap` library to open sockets and install filters to allow or disallow certain types of data to come through the socket. The filter may apply to all traffic passing through the specified network interface (or every interface if not specified). When the network interface receives a packet matching the filter criteria, additional actions can be triggered on the host, such as activation of a...
a13e DCV does not currently map a cloud-native finding directly to T1205.002. This page is included for research and coverage-planning context; when platform mappings are added, this answer will list them.
a13e CloudSigma does not currently publish a production Sigma rule for T1205.002. When rules are added, supported SIEM dialects will appear here after SigmaHQ validation and target-SIEM conversion pass.
No production rules are published for T1205.002 yet. The count grows when CloudSigma ships new rules tagged to T1205.002 or when DCV adds a cloud-native finding type that maps to the technique.
Run a free coverage scan in a13e DCV: it inspects your AWS, Azure, and GCP detection content + maps each existing detection to MITRE ATT&CK. Where T1205.002 is uncovered, DCV surfaces the gap with an actionable Sigma rule template you can copy into your SIEM. CloudSigma generates a fresh translation per SIEM dialect on demand.
Run a free coverage scan in a13e DCV at https://app.a13e.com. The scan reads your existing detection content (Splunk, Sentinel, Chronicle, Elastic) and reports a per-technique coverage map against MITRE ATT&CK. The output highlights which techniques your DCV instance currently catches and which ones need new rules from CloudSigma.
