T1632.001: Code Signing Policy Modification
Adversaries may modify code signing policies to enable execution of applications signed with unofficial or unknown keys. Code signing provides a level of authenticity on an app from a developer, guaranteeing that the program has not been tampered with and comes from an official source. Security controls can include enforcement mechanisms to ensure that only valid, signed code can be run on a device.
Mobile devices generally enable these security controls by default, such as preventing the installation of unknown applications on Android. Adversaries may modify these policies in a number of ways, including Input Injection or malicious configuration profiles.

Executive priority
T1632.001: Code Signing Policy Modification is an official MITRE ATT&CK technique. 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 T1632.001: Code Signing Policy Modification by reviewing the official ATT&CK relationships, mapped tactics (defense-evasion), supported platforms (Android, iOS), and available local telemetry before making detection or mitigation decisions.
Likely telemetry
- Official ATT&CK relationships and object metadata
- Identity, privilege, and authentication events
Detection direction
- Validate whether T1632.001: Code Signing Policy Modification 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.

Groups, software, and campaigns
G0112: Windshift
S0551: GoldenEagle
GoldenEagle is a piece of Android malware that has been used in targeting of Uyghurs, Muslims, Tibetans, individuals in Turkey, and individuals in China. Samples have been found as early as 2012.[1]
S0420: Dvmap
S0490: XLoader for iOS
XLoader for iOS is a malicious iOS application that is capable of gathering system information.[1] It is tracked separately from the XLoader for Android.
S0505: Desert Scorpion
Desert Scorpion is surveillanceware that has targeted the Middle East, specifically individuals located in Palestine. Desert Scorpion is suspected to have been operated by the threat actor APT-C-23.[1]
There are multiple close variants of Desert Scorpion, such as VAMP[2], GnatSpy[3], FrozenCell and SpyC23, which add some additional functionality but are not significantly different from the original malware.
S0485: Mandrake
Mandrake is a sophisticated Android espionage platform that has been active in the wild since at least 2016. Mandrake is very actively maintained, with sophisticated features and attacks that are executed with surgical precision.
Mandrake has gone undetected for several years by providing legitimate, ad-free applications with social media and real reviews to back the apps. The malware is only activated when the operators issue a specific command.[1]
