Tuning notes: Map proxy field names (host/url/login/cip) to your proxy sourcetype; for non-Zscaler proxies swap the sourcetype (e.g. pan:traffic, bluecoat:proxysg:access:syslog). Exclude known threat-research egress IPs. Feed newly reported TVTap lure domains into the match regex. Consider enriching client_ip with the MDM device owner for fast triage.

Technical analysis
RemControl is a previously undocumented Android banking trojan operated as Malware-as-a-Service (MaaS), analysed by Group-IB (report published 2026-09-23). Its C2 proxy domain bnbnhura.top was registered on 2026-05-12, roughly two months before the first samples; the first samples were submitted to VirusTotal on 2026-07-19. Group-IB tracks the first observed campaigns under the affiliate tag UNKK, found in a Branding class in every sample. Campaign tags seen include IT-NEW, IT-NEW4, FR-NEW, FR-NEW4, pt-v3, ARABIC2 and ARABIC3.
Distribution relies on fake Google Play pages impersonating the TVTap IPTV app, which is not on the official store, so users are used to sideloading it. The pages embed two Meta Pixel IDs, which Group-IB assesses as evidence of paid Meta advertising. An Italian campaign used six distribution URLs with Italian-localized pages that serve the APK only to mobile User-Agents with Italian IP addresses; the final download is a dl.php path on tvtap-liveapp.com. Droppers use the instal*tvtap*.apk naming convention, which was previously seen with Medusa payloads and switched to RemControl payloads around July 2026.
Infection chain: the dropper shows a WebView screen imitating a TVTap update and requests BIND_VPN_SERVICE. It then starts a local VPN that blocks network traffic from com.android.vending, which keeps Play Protect from scanning the install in real time. The dropper generates a fresh signing key in the Android Keystore for each install (certificate subject always CN=Android Debug, O=Android, C=US), so hash- and certificate-based detection fails. It installs and launches the payload through PackageInstaller.SessionParams, and the payload immediately requests Accessibility Service permission. Payload strings are Base64-encoded and XOR-obfuscated; newer payloads use a custom DEX packer whose key derives from the APK signing certificate.
Capabilities: the payload monitors the foreground app against a C2-provided target list and shows a full-screen WebView overlay whose HTML is fetched from the C2 at /overlay/{result_id} and never stored on the device. Overlays collect PINs, mobile banking codes and card expiry dates, and some are multi-step. It streams the screen with takeScreenshot() as WEBP frames over WebSocket, together with a UI node tree as JSON. It logs click, text, focus and selection events across apps. It injects taps, long presses, scrolls, swipes, gestures, text, clipboard and global actions. It reconstructs lock patterns from pattern-view grid coordinates across ten OEM skins. Self-preservation detects app-management, accessibility and factory-reset settings screens in 30+ languages and fires a back action to close them.
C2: on startup the malware fetches one of two Telegram channel pages in round-robin, finds a marker string (numeraZZZas) that appears twice in the HTML, Base64-URL decodes the text between the two occurrences and decrypts it with AES-128-CBC. The key and IV come from the SHA-256 of the marker (first 16 bytes key, last 16 bytes IV). The plaintext is the base C2 URL, so the operator can rotate servers without a new release. The primary channel is WebSocket with a JSON envelope (cmd, udid, rid, data): reg, log, update_apps, apps_report and start_overlay, with 20-second keepalive pings and exponential reconnect backoff of 1 to 30 seconds. The fallback is HTTP POST to /api. About 35 commands are documented.
Infrastructure and MaaS: the RemControl Proxy (bnbnhura.top, behind Cloudflare, FastAPI backend) relays to the final C2 and had publicly exposed API docs. The operator panel (definatelynoone.com and 157.90.179.116) exposed API docs showing bot management, an overlay template editor, a credential results viewer, a macro engine, a VNC session recorder with frame-by-frame replay and a build system with an affiliate tracking field. Each affiliate receives an APK built with configurable lure HTML, app name, accessibility label and package name. Over 100 admin endpoints were listed.
AI assistance and attribution: the proxy and panel API docs describe overlay and credential endpoints as handling 'quiz answers' and the remote-control features as 'parental-monitoring'. A test overlay had a complete AI assistant reply appended to its HTML. Some overlays contain Russian-language comments, so Group-IB assesses the overlay developer as likely Russian-speaking but not necessarily the core malware developer. Overlay images carry Adobe XMP metadata showing a UTC+8 timezone and Photoshop on Windows. Cleafy attributed Medusa samples using the same instal*tvtap*.apk naming to the UNKN affiliate botnet in 2024; UNKN and UNKK differ by one letter and both use Telegram dead-drops and target Italy and France, but Group-IB states a definitive link cannot be established. No CVE is involved and CVSS does not apply; severity is analyst-assigned.

Remediation
Immediate actions
- Block the listed domains, IPs and fake TVTap distribution URLs at DNS, proxy and mobile gateway
- Hunt MDM/EDR inventory for sideloaded APKs matching instal*tvtap*.apk and the listed SHA256 hashes
- Flag apps holding both BIND_VPN_SERVICE and Accessibility Service permission that are not from an official store
- Monitor mobile banking sessions for remote-control, overlay and anomalous session indicators and block them before users enter personal data
- Request takedown of fake TVTap Google Play look-alike pages and associated Meta ads
Workarounds
- Install apps only from official stores
- Deny Accessibility Service requests from apps that do not need them
- Run regular Play Protect scans
- Never enter PINs, mobile banking codes or card details into unexpected screens; contact the bank through official channels if fraud is suspected
Longer-term hardening
- Deploy session monitoring and digital risk protection to detect brand and layout abuse
- Run customer awareness on sideloading, IPTV lures and Accessibility permission prompts
- Enforce MDM policy blocking installation from unknown sources on managed devices
- Do not rely on hash or certificate signatures alone, since each install is re-signed with a new key
Affected and fixed versions
- Google — Android (sideloaded APK; Accessibility Service abuse)
Vulnerable versions: Devices that install the malicious TVTap APK and grant Accessibility Service - Retail banking customers — Mobile banking apps (30+ institutions in IT, FR, ES, PL, PT, CA, GCC)
Vulnerable versions: Customers of targeted institutions
Timeline
- RemControl Proxy C2 domain locked-ioc-30 registered, about two months before the first samples; infrastructure reported active from May 2026.
- First RemControl samples observed (July 2026, month precision per Group-IB); instal*tvtap*.apk droppers switch from Medusa to RemControl payloads around this time.
- Distribution domains locked-ioc-29 and tvtap-liveapp.com registered.
- First RemControl samples submitted to VirusTotal.
- Group-IB publishes its RemControl analysis; BleepingComputer covers it the same day.
- Help Net Security reports on RemControl; Infosecurity Magazine and TuttoAndroid follow on 2026-09-25.
