Executive Summary

Mobile devices are now the primary identity token for the enterprise: MFA prompts, OAuth refresh tokens, push approvals, and out-of-band verification all terminate on iOS/Android. In 2025, attackers exploit that reality with banking Trojans, commercial/mercenary spyware, stalkerware, loader frameworks, ad-fraud kits, and RATs that weaponize permissions (Accessibility, Notification Listener, VPN), social engineering (“urgent updates”), and zero/one-click exploits in messaging and browser surfaces.

What changed this year

  • Identity takeover > credential theft: session cookies, push MFA abuse, OTP interception through Notification Listener and SMS read permissions.
  • Loader ecosystems: “FakeUpdates” style droppers deliver modular payloads; same delivery playbook scales from commodity Trojans to high-end implants.
  • Enterprise MDM/EMM abuse**:** malicious profiles and sideloaded enterprise-signed apps deliver persistent footholds.
  • Cloud exfil + data monetization: instant sync to cloud drives; data-extortion sans ransomware is common.
  • AI both sides: attackers auto-personalize lures; defenders harness MTD/XDR + AI triage for anomaly clustering and faster isolation.

Bottom line: Treat mobile as Tier-1 endpoints: enforce managed OS updates, kill sideloading, contain script/installer flows, lock down high-risk permissions, and wire MTD/EDR + network egress controls. Pair with Zero-Trust access and strong identity governance.

Threat Taxonomy (What’s hitting fleets)

  1. Banking Trojans (e.g., overlay kits)
    • Goal: Steal credentials/2FA for banking, crypto, payments.
    • TTPs: Accessibility Service to draw overlays, read screen content; Notification Listener to hijack OTP; keylogging via accessibility.
    • Impact: Account draining, fraud, BEC pivots.
  2. Commercial/Mercenary Spyware (Pegasus-class)
    • Goal: Targeted surveillance of high-value users; endpoint harvesting after decryption.
    • TTPs: Zero/one-click exploits in iMessage/VoIP/WebKit; memory-resident stages; careful C2 hygiene.
    • Impact: Loss of confidentiality at leadership and diplomatic levels.
  3. Stalkerware & Enterprise “Grayware”
    • Goal: Covert tracking, mic/camera access, message read.
    • TTPs: Sideloaded APKs, misused MDM profiles; abusive accessibility hooks.
    • Impact: Privacy violations, legal/regulatory risk.
  4. Loader/Dropper Frameworks (e.g., “FakeUpdates” style)
    • Goal: Get any payload to run with a single tap; evade store screening.
    • TTPs: JS/HTML lures → ZIP/JS/ISO/MSI (Android via unknown sources), enterprise signing on iOS; second-stage from HTTPS CDN.
    • Impact: Multi-stage infections, rapid pivot to higher-value implants.
  5. Ad-Fraud/Clicker Kits
    • Goal: Monetize background taps/installs, proxy traffic; often a smokescreen.
    • Impact: Battery/data drain, privacy leaks, possible loader for worse payloads.
  6. RATs & Corporate Espionage
    • Goal: Persist, surveil, and siphon IP; become a stepping stone into SaaS/IdP via tokens.
    • TTPs: Accessibility + Device Admin, side-loading, cloned enterprise certs.

Attack Surface by Platform

Android (strengths & pain points)

  • Strengths: Runtime permissions; Play Protect; background restrictions; scoped storage.
  • Pain points: Sideloading (unknown sources); AccessibilityService misuse; Notification Listener for OTP; DRAW_OVER_OTHER_APPS overlays; easy persistence with Device Admin/Owner on unmanaged BYOD.
  • High-value alerts: New Accessibility services; apps requesting SMS read + notification access; VPN service creation by unsanctioned apps; unknown device admin.

iOS (strengths & pain points)

  • Strengths: Strong app sandbox, notarization, limited persistence, Lockdown Mode (great for high-risk users).
  • Pain points: Zero/one-click exploits in parsing surfaces (messaging, media); MDM/profile abuse (rogue enterprise-signed apps); re-infection by the same channel if hygiene remains weak.
  • High-value alerts: Unrecognized profiles/MDM enrollments; unusual crash logs (WebKit/IM frameworks); frequent short HTTPS posts to new domains.

Kill-Chain (Behavioral Model for Hunters)

  1. Initial Access
    • Smishing/DM lure → one-tap to malicious site → fake update/installer.
    • Zero-click payload into chat/VoIP leads to exploit chain.
    • On-path injection (rogue Wi-Fi/captive portal) injects drive-by.
  2. Execution
    • Android: apk install (unknown sources), or browser-assisted loader; iOS: exploit → shellcode → in-memory stage.
    • Child actions: background services, accessibility hooks, VPN service, notification listener registration.
  3. Persistence
    • Android: scheduled jobs, device admin/owner, accessibility re-enable; iOS: re-delivery triggers, enterprise profiles, or simple re-infection strategy.
  4. C2 & Module Fetch
    • TLS to rotating subdomains/cloud; small periodic beacons; device profiling.
  5. Objectives
    • Data harvesting (messages, files, tokens), OTP interception, microphone/camera, location; exfil to cloud.
    • Monetization: account takeover, data extortion, corporate access pivot.

This chain is stable across brands. Focus detection on behaviors (permissions, services, network) not static strings.

MITRE ATT&CK for Mobile (quick mapping)

  • Initial Access: T1475 Delivery via Authorized App Store (rare), T1476 Drive-By Compromise, T1477 Malicious Link
  • Execution: T1406 Obfuscated/Compressed Files, T1409 Exploit OS Vulnerability
  • Persistence: T1402 Broadcast Receivers, T1404 Malicious/Abused Accessibility, T1403 Modify System Partition (root/jailbreak)
  • Privilege Escalation: T1404 Accessibility Abuse, T1401 Exploit OS Vulnerability
  • Defense Evasion: T1407 Download/Install Additional Apps, T1408 Disguise/Obfuscate
  • Credential Access: T1411 Input Capture, T1414 Capture SMS/OTP
  • Discovery: T1420 File/Directory Discovery, T1422 Network Info Discovery
  • Exfiltration/C2: T1437 Exfiltration Over C2 Channel, T1430 Standard App Layer Protocol

High-Fidelity Detections (Drop-in Ideas)

Android (MDM/MTD policy + SIEM)

  • New Accessibility service not in allowlist → alert/quarantine.
  • Notification Listener granted + foreground service to new package → flag OTP interception risk.
  • VPN service created by unknown app → block until approved.
  • Device Admin/Owner change outside IT workflow → isolate & review.
  • Network: repeated short HTTPS posts to new domains within 10–20 minutes of install event.

iOS (Telemetry/MTD + Network)

  • New configuration profile/MDM enrollment outside IT channel.
  • Lockdown Mode disabled on high-risk users (policy gap).
  • Crash clusters in WebKit/IM frameworks within short interval (possible exploit attempts).
  • Network: small periodic TLS posts (200–3,000 bytes) to previously unseen hosts (C2 hygiene pattern).

Proxy/DNS (both platforms)

  • Alert on “NewDomain” POST bursts (3+ posts/30–60 mins) from the same device.
  • Block newly registered domains (NRDs) for 24–48h for unmanaged BYOD; place exceptions for business apps.

SOC Fast-Response Runbook (Mobile)

  1. Isolate the device from corporate resources (MTD quarantine / conditional access fail-closed).
  2. Block observed domains/IPs at DNS/HTTP egress; snapshot flows if possible.
  3. Collect:
    • Android: app list + permissions, Accessibility & Notification listeners, Device Admin state, VPN services, logs (where policy allows).
    • iOS: sysdiagnose & MVT analysis (where feasible), profile/MDM inventory, recent crash logs.
  4. Credential hygiene: reset account passwords from a known-clean workstation, revoke OAuth tokens, re-issue FIDO keys.
  5. Wipe & re-enroll if persistence unclear; re-provision from gold profile; smallest necessary restore.
  6. Hunt lateral paths: SaaS/OAuth consents, cloud file-share links, anomalous sign-ins.

Hardening That Works (Policy Baselines)

For Everyone

  • Latest OS & app updates auto-applied; rapid patch rings.
  • No sideloading (Android unknown sources = off); enterprise signing controlled via MDM.
  • App allowlist for permissions: Accessibility, Notification Listener, SMS read, VPN, Device Admin.
  • Browser policy: vendor-managed silent updates; users never install “browser updates” manually.
  • Egress: DNS filtering + HTTPS allowlists for sensitive cohorts; challenge NRDs.
  • Identity: FIDO2 for admins/execs; conditional access; short token TTLs; OAuth consent governance.
  • User training: show sample fake update prompts; drill “Report, don’t tap”.

For High-Risk Users (journalists, execs, diplomats)

  • Lockdown Mode (iOS); minimal app set; travel phone kits; separate “admin phone” from daily comms.
  • MTD with anomaly rules; SIEM correlation with SaaS/IdP signals.

For Enterprises

  • MDM/EMM mandatory; compliance gating ties to IdP (device posture → access).
  • MTD/XDR integrated: script/overlay/OTP-intercept anomalies block access.
  • Zero-Trust per-app VPN; private egress for corporate apps; no split tunneling for admin tools.
  • Backups & DR for mobile-connected data sources; IR playbooks include mobile rooting/jailbreak checks.

Program KPIs (What to show leadership)

  • MTTI/MTTR for mobile incidents.
  • % managed devices with MTD enforced and compliant.
  • % devices with Lockdown Mode (for high-risk cohort).
  • Sideloading rate (goal: near zero).
  • NewDomain POST blocks per 10k devices (should trend downward).
  • OAuth governance: unverified-publisher consents (goal: zero).
