T1636.003: Contact List
Adversaries may utilize standard operating system APIs to gather contact list data. On Android, this can be accomplished using the Contacts Content Provider. On iOS, this can be accomplished using the `Contacts` framework.
If the device has been jailbroken or rooted, an adversary may be able to access the Contact List without the user’s knowledge or approval.
Security context for executives and security teams
Contact List is a mobile ATT&CK sub-technique covering attempts by apps to collect a user’s address book through normal Android or iOS APIs, or without normal approval if the device is rooted or jailbroken. For leaders, the risk is not just privacy loss: contact data can expose executives, customers, partners, and internal relationships that may support follow-on targeting or surveillance.
Executive priority
Treat this as a mobile privacy and incident-readiness issue, especially for users with sensitive relationship data such as executives, government-facing teams, legal, HR, security, and critical operations personnel. The key governance question is whether the organization can show which mobile apps request or receive contacts access, whether users are guided to deny unnecessary access, and whether rooted or jailbroken devices are visible in mobile security processes.
Technical view
Validate coverage on Android and iOS for apps requesting or using contact-list access. On Android, review applications that declare or use access associated with the Contacts Content Provider. On iOS, review applications declaring or using the Contacts framework through required app metadata and user permission flows. Because official ATT&CK detection text is not provided, use the related DET0679 detection strategy as a mapping point but require local engineering to define the actual signals, thresholds, and response workflow. Pay special attention to rooted or jailbroken devices, where access may occur without normal user knowledge or approval.
Likely telemetry
- Mobile app inventory from managed devices, including installed applications and versions
- Android application manifest permissions related to contacts access
- iOS application Info.plist entries related to Contacts framework access
- Runtime permission grant or denial events where available
- Mobile device management or mobile threat defense records for app permissions and privacy access
Detection direction
- Inventory apps with contacts access and compare requested access to business need; many legitimate apps may request contacts, so context is required to reduce false positives.
- Prioritize alerts where contacts access appears in apps with weak business justification, recently installed apps, or apps on high-risk user devices.
- Correlate contact-list access with rooted or jailbroken status because ATT&CK notes that normal approval may be bypassed in that condition.
- Use relationship context to inform threat hunting: multiple Android and iOS malware/software entries are mapped to this behavior, but do not infer local exposure without device evidence.
- Document detection gaps explicitly because ATT&CK does not provide official detection logic for this object.
Mitigation priorities
- Start with M1011 User Guidance: train users to deny contacts access unless it is clearly required for the app’s business purpose.
- Provide specific guidance for high-risk mobile users on reviewing existing contacts permissions and avoiding risky permission grants.
- Include rooted or jailbroken device guidance in mobile policy because ATT&CK notes these states can weaken normal permission approval expectations.
- Use mobile app review and permission governance to support compliance evidence around sensitive personal or relationship data access.
Additional notes and limits
This object is a sub-technique of T1636 Protected User Data and replaces the revoked T1432 Access Contact List. Relationship mappings show use by several mobile software entries and some threat activity references, which supports the behavior’s relevance for mobile surveillanceware, RATs, spyware, and banking malware analysis. The supplied object does not specify ATT&CK tactics.
Official ATT&CK detection guidance is not provided, and the related DET0679 detection strategy details are not included in the supplied fields. Practical detection depends on local MDM/UEM, mobile threat defense, OS logging, app inventory quality, and whether Android/iOS permission telemetry is available.

G0112: Windshift
S0549: SilkBean
S1241: RatMilad
RatMilad is an Android remote access tool (RAT) with spyware functionality that has been used to target enterprise mobile devices in the Middle East since at least 2021. Variants of RatMilad have been disguised as VPN applications and a fake app named NumRent. Upon installation, RatMilad employs multiple Collection techniques to collect sensitive information before uploading the collected data to its command and control (C2) server. [1]
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]
S1077: Hornbill
S0506: ViperRAT
S1185: LightSpy
First observed in 2018, LightSpy is a modular malware family that initially targeted iOS devices in Southern Asia before expanding to Android and macOS platforms. It consists of a downloader, a main executable that manages network communications, and functionality-specific modules, typically implemented as `.dylib` files (iOS, macOS) or `.apk` files (Android). LightSpy can collect VoIP call recordings, SMS messages, and credential stores, which are then exfiltrated to a command and control (C2) server.[1]
S1079: BOULDSPY
S0550: DoubleAgent
DoubleAgent is a family of RAT malware dating back to 2013, known to target groups with contentious relationships with the Chinese government.[1]
S1243: DCHSpy
DCHSpy is an Android spyware likely used by MuddyWater. DCHSpy uses political decoys and masquerades as legitimate applications, such as VPNs and banking applications, to trick victims into downloading the malware. Once downloaded, DCHSpy collects information from the device and exfiltrates the data to the command and control (C2) server.[1]
S0411: Rotexy
S1067: FluBot
FluBot is a multi-purpose mobile banking malware that was first observed in Spain in late 2020. It primarily spread through European countries using a variety of SMS phishing messages in multiple languages.[1][2] An international law enforcement operation of 11 countries eventually disrupted the spread of FluBot.[3]
S1069: TangleBot
TangleBot is SMS malware that was initially observed in September 2021, primarily targeting mobile users in the United States and Canada. TangleBot has used SMS text message lures about COVID-19 regulations and vaccines to trick mobile users into downloading the malware, similar to FluBot Android malware campaigns.[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]
