S0124: Pisloader

Pisloader is a malware family that is notable due to its use of DNS as a C2 protocol as well as its use of anti-analysis tactics. It has been used by APT18 and is similar to another malware family, HTTPBrowser, that has been used by the group. [1]

It has been used by [APT18](https://attack.mitre.org/groups/G0026) and is similar to another malware family, [HTTPBrowser](https://attack.mitre.org/software/S0070), that has been used by the group.

Executive priority

S0124: Pisloader 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 S0124: Pisloader by reviewing the official ATT&CK relationships, mapped tactics (the mapped ATT&CK tactic context), supported platforms (Windows), 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 S0124: Pisloader 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.

Generated from the cited source records. This long-tail analysis has not been individually reviewed by a named human.

Techniques used

This mirrors the MITRE pattern of making group, software, campaign, and technique relationships scannable. Relationship notes come from mirrored ATT&CK relationship text when available.

9 rows
DomainIDNameRelationship / procedure
EnterpriseT1547.001Registry Run Keys / Startup FolderSub-technique

Pisloader establishes persistence via a Registry Run key.[1]

EnterpriseT1059.003Windows Command ShellSub-technique

Pisloader uses cmd.exe to set the Registry Run key value. It also has a command to spawn a command shell.[1]

EnterpriseT1132.001Standard EncodingSub-technique

Responses from the Pisloader C2 server are base32-encoded.[1]

EnterpriseT1016System Network Configuration Discovery

Pisloader has a command to collect the victim's IP address.[1]

EnterpriseT1071.004DNSSub-technique

Pisloader uses DNS as its C2 protocol.[1]

EnterpriseT1027Obfuscated Files or Information

Pisloader obfuscates files by splitting strings into smaller sub-strings and including "garbage" strings that are never used. The malware also uses return-oriented programming (ROP) technique and single-byte XOR to obfuscate data.[1]

EnterpriseT1105Ingress Tool Transfer

Pisloader has a command to upload a file to the victim machine.[1]

EnterpriseT1082System Information Discovery

Pisloader has a command to collect victim system information, including the system name and OS version.[1]

EnterpriseT1083File and Directory Discovery

Pisloader has commands to list drives on the victim machine and to list file information for a given directory.[1]
