Executive priority

S0468: Skidmap is an official MITRE ATT&CK software. Glexia treats it as defensive behavior context for prioritizing monitoring, control validation, and response planning without using the object by itself as an attribution claim.

Technical view

Security teams should validate S0468: Skidmap by reviewing the official ATT&CK relationships, mapped tactics (the mapped ATT&CK tactic context), supported platforms (Linux), and available local telemetry before making detection or mitigation decisions.

Likely telemetry

  • Official ATT&CK relationships and object metadata
  • Network, endpoint, and security-tool telemetry

Detection direction

  • Validate whether S0468: Skidmap appears in your detection coverage and tabletop scenarios.
  • Use the object to align executive risk language with SOC, incident response, and detection engineering work.
  • Do not treat ATT&CK relationship context as attribution without corroborating evidence.

Mitigation priorities

  • Map the object to existing controls and identify missing telemetry or response ownership.
  • Prioritize mitigations that reduce exposure on the listed platforms and tactics.
  • Review adjacent ATT&CK relationships before changing policy, detections, or reporting language.
Additional notes and limits

Baseline Glexia take generated from the official MITRE ATT&CK STIX object, source hash, tactics, platforms, and detection fields. It is safe to replace with a richer model-generated take for the same source hash later.

This baseline take is source-grounded and schema-validated, but it does not include environment-specific telemetry, incident evidence, or threat-intelligence corroboration.

Skidmap is a kernel-mode rootkit used for cryptocurrency mining.[1]

EnterpriseT1098.004SSH Authorized KeysSub-technique

Skidmap has the ability to add the public key of its handlers to the authorized_keys file to maintain persistence on an infected host.[1]

EnterpriseT1105Ingress Tool Transfer

Skidmap has the ability to download files on an infected host.[1]

EnterpriseT1027.013Encrypted/Encoded FileSub-technique

Skidmap has encrypted it's main payload using 3DES.[1]

EnterpriseT1036.005Match Legitimate Resource Name or LocationSub-technique

Skidmap has created a fake rm binary to replace the legitimate Linux binary.[1]

EnterpriseT1685Disable or Modify Tools

Skidmap has the ability to set SELinux to permissive mode.[1]

EnterpriseT1053.003CronSub-technique

Skidmap has installed itself via crontab.[1]

EnterpriseT1083File and Directory Discovery

Skidmap has checked for the existence of specific files including /usr/sbin/setenforce and /etc/selinux/config. It also has the ability to monitor the cryptocurrency miner file and process. [1]

EnterpriseT1518.001Security Software DiscoverySub-technique

Skidmap has the ability to check if /usr/sbin/setenforce exists. This file controls what mode SELinux is in.[1]

EnterpriseT1547.006Kernel Modules and ExtensionsSub-technique

Skidmap has the ability to install several loadable kernel modules (LKMs) on infected machines.[1]

EnterpriseT1556.003Pluggable Authentication ModulesSub-technique

Skidmap has the ability to replace the pam_unix.so file on an infected machine with its own malicious version that accepts a specific backdoor password for all users.[1]

EnterpriseT1082System Information Discovery

Skidmap has the ability to check whether the infected system’s OS is Debian or RHEL/CentOS to determine which cryptocurrency miner it should use.[1]

EnterpriseT1014Rootkit

Skidmap is a kernel-mode rootkit that has the ability to hook system calls to hide specific files and fake network and CPU-related statistics to make the CPU load of the infected machine always appear low.[1]

EnterpriseT1057Process Discovery

Skidmap has monitored critical processes to ensure resiliency.[1]

EnterpriseT1140Deobfuscate/Decode Files or Information

Skidmap has the ability to download, unpack, and decrypt tar.gz files .[1]

EnterpriseT1059.004Unix ShellSub-technique

Skidmap has used pm.sh to download and install its main payload.[1]
