The Chameleon Android banking trojan has evolved from consumer-focused banking fraud into campaigns aimed at employees, broadening the risk from personal account theft to potential compromise of business banking access. First observed targeting users in Australia and Poland while impersonating brands such as CoinSpot, a government agency, and Poland’s IKO bank, the malware later appeared in campaigns against victims in Canada and Europe disguised as a CRM application for hospitality workers and, separately, as a fake bank security app. Researchers said the operators appear to be using trusted-brand impersonation and workplace-themed lures to steal credentials from devices that may also provide access to corporate financial systems.
Chameleon abuses Android’s Accessibility Service to automate permissions, disable Google Play Protect, interfere with uninstallation, and carry out credential theft through overlays, keylogging, cookie theft, lock grabbing, and SMS interception. In the newer activity, operators used a multi-stage infection chain with a dropper designed to bypass Android 13+ restrictions before installing the final payload under the pretense of reinstalling the app. Earlier analysis also found the malware communicating with a command-and-control server at 146.70.41.143:7242 and exfiltrating device details, cookies, keylogs, and SMS data, while retaining an unused runtime payload-loading capability via DexClassLoader, indicating continued development beyond its already mature banking trojan features.

3 events from the most recent confirmed update back to the earliest known activity.
Cyble reported that the Android banking trojan it named Chameleon had been active since January 2023. Early activity included targeting mobile users in Australia and Poland with lures impersonating services such as CoinSpot, an Australian government agency, and Poland’s IKO bank.
ThreatFabric observed new Chameleon campaigns in July 2024 targeting victims in Canada and Europe. The activity included a CRM-themed lure aimed at hospitality employees and separate impersonation of a bank security application for customers of specific financial institutions.
Cyble Research & Intelligence Labs published analysis of a new Android banking trojan named Chameleon, detailing its use of Accessibility Service abuse, credential theft, cookie theft, keylogging, SMS interception, and communication with its command-and-control server. The report also noted an unused runtime payload-loading capability via DexClassLoader.

Infoblox Threat Intel and Vietnamese non-profit Chong Lua Dao linked an Android banking trojan to scam compounds in Cambodia, including the **K99 Triumph City** complex in Sihanoukville, in what researchers described as a malware-as-a-service operation backed by forced labor. The investigation combined DNS anomaly detection, malware analysis, exposed command-and-control infrastructure, and testimony from escapees who said trafficked workers were compelled to send phishing messages and coach victims into installing malicious Android apps from spoofed websites impersonating banks, government agencies, airlines, and delivery services. Researchers said the operation targeted victims in **21 countries** across four continents and remained active, registering about **35 new lure domains per month** while rotating infrastructure and reusing domains for new scams. Once installed, the trojan enabled real-time device surveillance, SMS and call interception, credential theft, biometric capture and bypass, fake banking overlays, data exfiltration, and remote manipulation of banking sessions to steal funds. The infrastructure showed segmented admin panels by country and apparent customer, indicating a centrally managed, multilingual criminal service with overlaps to activity previously associated with **Vigorish Viper** and **Vault Viper**.

Zimperium zLabs identified four Android malware families—**RecruitRat, SaferRat, Astrinox, and Massiv**—in active campaigns targeting users of more than **800 banking, cryptocurrency, and social media apps**. The malware is being spread through phishing sites, smishing messages, fake job application and streaming lures, counterfeit app-store pages, and bogus updates that trick victims into installing malicious APKs. Researchers said the campaigns rely heavily on overlay attacks, with fake login screens placed over legitimate apps to steal credentials; **RecruitRat** alone reportedly includes more than **700** fraudulent login pages. Once installed, the trojans abuse Android features including **Accessibility Services**, the **Session Installation API**, **MediaProjection**, overlays, and **WebView** to gain persistence, intercept SMS and one-time passwords, log keystrokes, enumerate apps, steal contacts, freeze screens, stream displays, and remotely control infected devices. The malware also uses anti-analysis techniques such as APK tampering, encrypted strings, reflection, dynamic DEX loading, and environment-aware execution, while command-and-control traffic is sent over HTTPS or WebSockets, with RecruitRat additionally using **RC4** encryption. Researchers warned the activity creates enterprise risk because infected employee devices can enable account takeover, bypass MFA, and expose corporate resources.

Researchers reported two Android banking malware campaigns using staged droppers to evade detection and steal financial data from mobile users. Zscaler ThreatLabz said a fake **Document Reader** app on Google Play was downloaded more than 10,000 times before removal and later fetched the **Anatsa** payload from a remote server, while CYFIRMA identified **KYCShadow** being distributed through fake KYC verification apps sent over WhatsApp to bank customers in India. In both cases, the initial apps appeared legitimate, then installed secondary malicious components designed to bypass early screening and analysis. Once deployed, the malware sought high-risk permissions to hijack accounts, intercept SMS-based one-time passwords, and overlay banking apps to capture credentials. Anatsa was reported to target more than **831 financial institutions** globally, including banks and cryptocurrency platforms, using obfuscation and anti-analysis techniques, while KYCShadow collected data such as mobile numbers, Aadhaar details, ATM PINs, and card information, then used Firebase Cloud Messaging and a full-tunnel VPN for command-and-control and traffic redirection. Researchers urged users to uninstall suspicious apps and avoid software delivered through messaging platforms, and advised defenders to monitor indicators including `jsonapi[.]biz`, `jsonserv[.]biz`, and `jsonserv[.]xyz`.
