T1429: Audio Capture
Adversaries may capture audio to collect information by leveraging standard operating system APIs of a mobile device. Examples of audio information adversaries may target include user conversations, surroundings, phone calls, or other sensitive information.
Android and iOS, by default, require that applications request device microphone access from the user.
On Android devices, applications must hold the `RECORD_AUDIO` permission to access the microphone or the `CAPTURE_AUDIO_OUTPUT` permission to access audio output. Because Android does not allow third-party applications to hold the `CAPTURE_AUDIO_OUTPUT` permission by default, only privileged applications, such as those distributed by Google or the device vendor, can access audio output.[1] However, adversaries may be able to gain this access after successfully elevating their privileges. With the `CAPTURE_AUDIO_OUTPUT` permission, adversaries may pass the `MediaRecorder.AudioSource.VOICE_CALL` constant to `MediaRecorder.setAudioOutput`, allowing capture of both voice call uplink and downlink.[2]
On iOS devices, applications must include the `NSMicrophoneUsageDescription` key in their `Info.plist` file to access the microphone.[3]
Security context for executives and security teams
Audio Capture matters because a compromised or abusive mobile app can turn a phone into a collection device for conversations, surroundings, calls, or other sensitive audio. For executives and security leaders, this is less about generic malware and more about protecting high-value mobile users, sensitive meetings, legal/compliance discussions, and operational environments where phones are present. ATT&CK notes Android and iOS permission gates, but the relationship context shows this behavior is common enough across mobile spyware and RAT families to merit explicit mobile security validation.
Executive priority
Prioritize this as a mobile privacy, executive protection, and incident response readiness issue. Leaders should ask whether managed mobile devices are kept on recent OS versions, whether microphone permissions are reviewed for business justification, and whether the organization can produce evidence during an investigation showing which apps had microphone access. This is especially relevant for high-risk users and environments where recorded speech could affect negotiations, regulated data handling, or operational security.
Technical view
For Android and iOS, validate controls around microphone authorization and visibility. Android apps require RECORD_AUDIO for microphone access; CAPTURE_AUDIO_OUTPUT is normally limited to privileged applications but may become relevant after privilege elevation. iOS apps require NSMicrophoneUsageDescription in Info.plist to request microphone access. Since ATT&CK provides no official detection text, SOC and mobile security teams should base coverage validation on the related detection strategy DET0673, local MDM/mobile security telemetry, app inventory, permission state, OS version, jailbreak/root indicators where available, and investigations of apps with unjustified microphone access.
Likely telemetry
- Mobile device inventory with Android/iOS platform and OS version
- Installed application inventory and app provenance where available
- Application permission state, especially microphone access on Android and iOS
- Android manifest permissions such as RECORD_AUDIO and any indication of privileged audio-output access such as CAPTURE_AUDIO_OUTPUT
- iOS app metadata such as NSMicrophoneUsageDescription where available
Detection direction
- Confirm whether DET0673 or an equivalent internal detection strategy is implemented for mobile audio capture behavior; ATT&CK does not provide native detection guidance for this technique.
- Tune around permission context: microphone access alone is not malicious, so prioritize apps with no business need, suspicious provenance, high-risk users, or co-occurring root/jailbreak/privilege-elevation signals.
- Review Android cases where privileged permissions or elevated access could change expected access boundaries, especially around CAPTURE_AUDIO_OUTPUT and voice-call audio capture.
- On iOS, validate whether app review, MDM, or forensic workflows can identify apps requesting microphone access through NSMicrophoneUsageDescription and correlate that with user and device risk.
- Expect blind spots where mobile telemetry is limited by OS privacy controls, unmanaged/BYOD scope, lack of app-permission history, or inability to inspect privileged or jailbroken devices.
Mitigation priorities
- Keep mobile operating systems current, aligning with ATT&CK mitigation M1006 Use Recent OS Version, because newer releases may add security architecture improvements as well as patches.
- Provide user guidance, aligning with M1011, on reviewing microphone permission prompts, denying unnecessary access, and reporting unexpected microphone indicators or suspicious apps.
- Apply risk-based mobile app governance: inventory apps, review microphone permissions for business justification, and reduce unnecessary access for managed devices.
- For high-risk users, validate incident response procedures for mobile collection: app inventory capture, permission review, OS version check, and escalation when spyware or RAT indicators are present.
- Use local policy and compliance requirements to define evidence retention for device posture, app permissions, and user guidance completion.
Additional notes and limits
The relationship context associates Audio Capture with multiple mobile campaigns, groups, and software families, including Android and iOS examples, which supports treating it as a recurring mobile surveillance behavior rather than a niche permission issue. However, those relationships do not prove current activity in any specific environment. The strongest defensive value is validating whether mobile governance and investigations can distinguish legitimate microphone use from suspicious or unjustified access.
ATT&CK lists no tactics for this object and provides no official detection text. The supplied fields identify platforms, permissions, external references, mitigations M1006 and M1011, and related detection strategy DET0673, but do not include detailed analytic logic. Local device management coverage, BYOD policy, OS restrictions, and available mobile telemetry will determine practical detectability.

Groups, software, and campaigns
G0112: Windshift
S0327: Skygofree
S9005: DocSwap
DocSwap is an Android malware first identified in 2025, and attributed to Kimsuky. DocSwap’s name is a combination of its Korean name “문서열람 인증 앱” (Document Viewing Authentication App) and a phishing page masquerading as CoinSwap at the C2 address. Based on DocSwap’s name and Korean-language strings, DocSwap potentially targets mobile device users in South Korea. Several variants of DocSwap exist; one of the latest samples indicates that the adversary added a native decryption function that decrypts an internal APK.[1][2]
S0316: Pegasus for Android
Pegasus for Android is the Android version of malware that has reportedly been linked to the NSO Group. [1] [2] The iOS version is tracked separately under Pegasus for iOS.
S0295: RCSAndroid
RCSAndroid is Android malware. [1]
S0507: eSurv
S1079: BOULDSPY
S0318: XLoader for Android
XLoader for Android is a malicious Android app first observed targeting Japan, Korea, China, Taiwan, and Hong Kong in 2018. It has more recently been observed targeting South Korean users as a pornography application.[1][2] It is tracked separately from the XLoader for iOS.
S1082: Sunbird
S0408: FlexiSpy
S0489: WolfRAT
S0328: Stealth Mango

S0535: Golden Cup
Golden Cup is Android spyware that has been used to target World Cup fans.[1]
C0033: C0033
C0033 was a PROMETHIUM campaign during which they used StrongPity to target Android users. C0033 was the first publicly documented mobile campaign for PROMETHIUM, who previously used Windows-based techniques.[1]
C0054: Operation Triangulation
Operation Triangulation is a mobile campaign targeting iOS devices.[1] The unidentified actors used zero-click exploits in iMessage attachments to gain Initial Access, then executed exploits and validators, such as Binary Validator before finally executing the TriangleDB implant.
