Security context for executives and security teams

Automation confidenceMedium

S0264: OopsIE describes [OopsIE](https://attack.mitre.org/software/S0264) is a Trojan used by [OilRig](https://attack.mitre.org/groups/G0049) to remotely execute commands as well as upload/download files to/from victims. (Citation: Unit 42 OopsIE! Feb 2018)

Executive priority

S0264: OopsIE 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 S0264: OopsIE 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 S0264: OopsIE 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.

EnterpriseT1074.001Local Data StagingSub-technique

OopsIE stages the output from command execution and collected files in specific folders before exfiltration.[1]

EnterpriseT1030Data Transfer Size Limits

OopsIE exfiltrates command output and collected files to its C2 server in 1500-byte blocks.[1]

EnterpriseT1140Deobfuscate/Decode Files or Information

OopsIE concatenates then decompresses multiple resources to load an embedded .Net Framework assembly.[1]

EnterpriseT1070.004File DeletionSub-technique

OopsIE has the capability to delete files and scripts from the victim's machine.[2]

EnterpriseT1047Windows Management Instrumentation

OopsIE uses WMI to perform discovery techniques.[2]

EnterpriseT1132.001Standard EncodingSub-technique

OopsIE encodes data in hexadecimal format over the C2 channel.[1]

EnterpriseT1082System Information Discovery

OopsIE checks for information on the CPU fan, temperature, mouse, hard disk, and motherboard as part of its anti-VM checks.[2]

EnterpriseT1497.001System ChecksSub-technique

OopsIE performs several anti-VM and sandbox checks on the victim's machine. One technique the group has used was to perform a WMI query SELECT * FROM MSAcpi_ThermalZoneTemperature to check the temperature to see if it’s running in a virtual environment.[2]

EnterpriseT1071.001Web ProtocolsSub-technique

OopsIE uses HTTP for C2 communications.[1][2]

EnterpriseT1059.003Windows Command ShellSub-technique

OopsIE uses the command prompt to execute commands on the victim's machine.[1][2]

EnterpriseT1560.003Archive via Custom MethodSub-technique

OopsIE compresses collected files with a simple character replacement scheme before sending them to its C2 server.[1]

EnterpriseT1105Ingress Tool Transfer

OopsIE can download files from its C2 server to the victim's machine.[1][2]

EnterpriseT1059.005Visual BasicSub-technique

OopsIE creates and uses a VBScript as part of its persistent execution.[1][2]

EnterpriseT1560.001Archive via UtilitySub-technique

OopsIE compresses collected files with GZipStream before sending them to its C2 server.[1]

EnterpriseT1053.005Scheduled TaskSub-technique

OopsIE creates a scheduled task to run itself every three minutes.[1][2]

EnterpriseT1027.002Software PackingSub-technique

OopsIE uses the SmartAssembly obfuscator to pack an embedded .Net Framework assembly used for C2.[1]

EnterpriseT1124System Time Discovery

OopsIE checks to see if the system is configured with "Daylight" time and checks for a specific region to be set for the timezone.[2]

EnterpriseT1027Obfuscated Files or Information

OopsIE uses the Confuser protector to obfuscate an embedded .Net Framework assembly used for C2. OopsIE also encodes collected data in hexadecimal format before writing to files on disk and obfuscates strings.[1][2]

EnterpriseT1041Exfiltration Over C2 Channel

OopsIE can upload files from the victim's machine to its C2 server.[1]

G0049: OilRig

OilRig is a suspected Iranian threat group that has targeted Middle Eastern and international victims since at least 2014. The group has targeted a variety of sectors, including financial, government, energy, chemical, and telecommunications. It appears the group carries out supply chain attacks, leveraging the trust relationship between organizations to attack their primary targets. The group works on behalf of the Iranian government based on infrastructure details that contain references to Iran, use of Iranian infrastructure, and targeting that aligns with nation-state interests.[1][2][3][4][5][6][7]
