C0061: Operation Digital Eye
Operation Digital Eye was conducted in June and July of 2024 by suspected People's Republic of China (PRC)-nexus threat actors targeting business-to-business IT service providers in Southern Europe. Operation Digital Eye activity included the use of Visual Studio Code tunnels for command and control (C2) and custom lateral movement capabilities. Overlaps in tooling between Digital Eye and previous China-nexus campaigns, Operation Soft Cell and Operation Tainted Love, indicate the potential use of shared vendors or digital quartermasters.[1]

Executive priority
C0061: Operation Digital Eye is an official MITRE ATT&CK campaign. 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 C0061: Operation Digital Eye by reviewing the official ATT&CK relationships, mapped tactics (the mapped ATT&CK tactic context), supported platforms (the platforms named in the official object), and available local telemetry before making detection or mitigation decisions.
Likely telemetry
- Official ATT&CK relationships and object metadata
Detection direction
- Validate whether C0061: Operation Digital Eye 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.

Treat this object as behavior context, not an attribution claim. Validate the related groups, software, data sources, and mitigations against official ATT&CK relationships and your own telemetry before making control-coverage decisions.
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.

PHPsert is a webshell used to execute PHP code that has been in use since at least 2023 against targets in Japan, Singapore, Peru, Taiwan, Iran, Republic of Korea, and the Philippines. PHPsert is not typically deployed as a standalone but integrated into web content such as text editors and content management systems.[1]
