<p>Adversary installs or abuses IDE extensions via CLI or direct write to profile directories and then communicates with marketplaces or remote tunnel services. Chain: auditd execve (code/idea/eclipse) with install/update flags or writes under ~/.vscode/extensions, ~/.config/JetBrains → outbound flows to .visualstudio.com, marketplace.visualstudio.com, .jetbrains.com, githubusercontent.com, or SSH/WebSocket tunnel endpoints → optional ssh/node processes spawned by IDE.</p>

Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| auditd:SYSCALL | execve | DC0032 Process Creation |
| auditd:SYSCALL | open,creat,rename,write | DC0039 File Creation |
| NSM:Flow | Connections from IDE hosts to marketplace/tunnel domains | DC0078 Network Traffic Flow |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
IDEPaths | Per-distro/profile extension directories differ; tune for Chromium/JetBrains snap/flatpak paths. |
DomainAllowlist | Enterprise-approved repos and proxies to reduce FPs. |
UserRoleScope | Limit to non-developer users or production servers. |
TimeWindow | Join horizon across file, process, and network telemetry. |
