Experts in cybersecurity have revealed that Chameleon, a malicious application for Android devices, has made a comeback with an improved version that now targets users in those countries as well as the United Kingdom and Italy.
This banking trojan is similar to any other virus that infects a system and then slips under its skin by avoiding going through the platform’s biometric activities.

Chameleon’s Enhanced Iteration Targets the U.K. and Italy
Chameleon, a notorious piece of malware that targets Android banking systems, has undergone a substantial metamorphosis, expanding its reach to now encompass users in the United Kingdom and Italy.
ThreatFabric, a Dutch mobile security company, demonstrates its expertise in carrying out Device Takeover (DTO) by utilizing the accessible service by highlighting the progression of this banking malware.
When it was first discovered in April 2023, Chameleon was mostly directed toward users in Poland and Australia. The malware is primarily concerned with gathering sensitive data and carrying out overlay attacks. It is well-known for exploiting the accessibility service that Android provides.
CoinSpot, a cryptocurrency marketplace, and the Australian Taxation Office were among the organizations that were impersonated in earlier versions of the software.
New Delivery Mechanism: Zombinder Integration Amplifies Threat
The most recent discoveries indicate that Chameleon has modified its delivery technique, which now makes use of Zombinder, which is a dropper-as-a-service that is readily available.
It was previously believed that Zombinder had been dormant; however, it has just reemerged with the capability to circumvent Android’s ‘Restricted Settings’ feature. According to The Hacker News, this dropper-as-a-service creates a powerful danger by attaching malicious payloads to legitimate applications.
Masquerading as Google Chrome: Deceptive Package Names
In order to conceal themselves, the malicious components that deploy Chameleon take on the appearance of the genuine Google Chrome web browser instead. Z72645c414ce232f45.Z35aad4dde2ff09b48 and com.busy are the names of the software packages.They are used to mislead users for the purpose of highlighting the misleading strategies employed by the virus.
The proficient ability of the improved Chameleon version to commit Device Takeover (DTO) fraud is a concerning characteristic of this variation. By utilizing the accessibility service, the malicious software is able to carry out actions that are not authorized on the device of the victim.
This banking trojan runs checks on the Android version, specifically encouraging users with Android 13 or later to enable the accessibility service. This is done in order to increase the success rate of the trojan.

Disrupting Biometric Operations: Covert Manipulation via Android APIs
An innovative approach to disrupting biometric activities is presented by the evolving Chameleon. In a stealthy manner, it switches the authentication for the lock screen from biometrics to a personal identification number (PIN), which enables the malware to unlock the smartphone whenever it wants by utilizing the accessibility service. Because of this subtle manipulation, concerns have been raised regarding the malware’s capacity to breach device security in a straightforward manner.
Regarding this banking trojan, Zimperium detailed their most recent thoughts on the proliferation of malicious software on Android devices. A disturbing trend reveals that 1,800 financial applications are being targeted by 29 different families of malware, including 10 new families. These families are spread across 61 nations.
The United States of America, the United Kingdom, and Italy are at the top of the list of countries that are being attacked, which highlights the global reach of these dangers.
The advent of the new Chameleon banking trojan is yet another illustration of the complex and ever-changing nature of the threat landscape that exists within the Android ecosystem. According to the most recent analysis published by ThreatFabric, “this variant demonstrates increased resilience and advanced new features.” This variant is an evolution from its prior iteralization.
