Rise of Xenomorph: Exploring the Menace of an Android Banking Trojan Targeting Users in US and Canada

Malware & Threats: Xenomorph Android Banking Trojan Targeting Users in US, Canada

Overview

The Xenomorph Android banking trojan, which was initially detailed in February 2022 and is likely linked to the infamous banking trojan Alien, has expanded its target list to include North American users. Online fraud detection firm ThreatFabric reports that recently identified Xenomorph samples show an increase in efficiency and a wider range of targets, including financial institutions in the US and Canada, as well as cryptocurrency wallets.

Modus Operandi

Xenomorph relies on overlays to steal users’ personal and login information. It can intercept notifications and SMS messages to bypass two-factor authentication. The malware utilizes an Automated Transfer System (ATS) framework, which supports a wide range of actions that can manipulate infected devices, harvest information, disable security features, and hide malicious activity. Distributed via phishing pages posing as a Chrome update, Xenomorph has been updated with new overlays for financial institutions and crypto wallets, allowing it to target more than 30 financial applications in the US, 25 in Spain, and over 15 banking applications in Canada.

Advanced Features

The recently observed Xenomorph samples contain more than 100 specifically crafted overlays to steal personally identifiable and financial information from victim devices. The malware has also been updated with new commands, including the ability to mimic other applications running on the device to avoid triggering behavior detection. It can prevent the device from going into sleep mode and simulate a touch on specific screen coordinates.

RisePro Stealer and Distribution Service

ThreatFabric discovered that the Xenomorph malware operators did not restrict access to their distribution server, which contains information on Xenomorph‘s distribution and evidence that desktop users are being targeted as well. The analysis of the files on the distribution server reveals the use of the RisePro stealer, Private Loader, and LummaC2 stealer. This suggests a possible connection between the threat actors behind Xenomorph and other malware families or the possibility that Xenomorph is being sold as a Malware-as-a-Service (MaaS) to actors who operate it along with other malware.

Extent of the Campaign

ThreatFabric states that the Xenomorph campaign is heavily focused on Spain, with over 3,000 downloads in a few weeks, followed by significant download numbers from the United States and Portugal. The malware is targeting a wide range of financial applications, indicating a comprehensive and widespread campaign.

Editorial Analysis

Evolution of Android Banking Trojans

The Xenomorph Android banking trojan showcases the ever-increasing sophistication of Android malware. It has evolved from its initial targeting of European banking applications and cryptocurrency wallets to now include North American users. By expanding its target list, Xenomorph demonstrates a heightened level of adaptability and a response to the shifting landscape of digital banking. This trend highlights the importance of continuous security updates and awareness among users to protect their personal and financial information.

The Threat to Mobile Banking

The rise of mobile banking has made smartphones an appealing target for hackers and cybercriminals. With the increasing popularity of mobile banking apps and the convenience they offer, users are more vulnerable to malware attacks like the Xenomorph trojan. The ability of Xenomorph to effectively bypass two-factor authentication and steal personal information through overlays poses significant risks to mobile banking customers. This alarming development calls for increased security measures and constant vigilance on the part of financial institutions and users alike.

Global Reach and Collaboration

The Xenomorph campaign’s global reach, with notable focus on Spain, the United States, and Portugal, showcases the truly international nature of cybercrime. Threat actors are constantly adapting and cooperating with each other to develop and distribute malware like Xenomorph. The discovery of the Xenomorph distribution server also highlights the interconnectedness of different malware families, suggesting possible collaboration or the commercialization of malware-as-a-service. This development underscores the need for international collaboration among law enforcement agencies and cybersecurity professionals to effectively combat cybercrime.

Advice to Users and Institutions

User Awareness and Vigilance

Users must maintain a high level of awareness and vigilance when conducting financial transactions on their mobile devices. It is crucial to verify the authenticity of any app or update before downloading or installing it. Users should only download apps from trusted sources such as official app stores and regularly update their devices and applications with the latest security patches.

Enable Additional Security Measures

Users should activate additional security measures provided by their banking apps, such as biometric authentication and transaction monitoring. Enabling two-factor authentication is essential to add an extra layer of protection against malicious actions like overlay attacks.

Regularly Monitor Financial Transactions

Users must regularly monitor their financial transactions, keeping a close eye on their bank statements, credit card bills, and cryptocurrency wallets. Any suspicious activity or unauthorized transactions should be reported immediately to the respective financial institutions or service providers.

Collaboration between Financial Institutions and Cybersecurity Experts

Financial institutions must collaborate closely with cybersecurity experts to detect and prevent the spread of malware like Xenomorph. Regular security assessments, audits, and employee training programs are crucial to maintaining a robust and secure infrastructure. Sharing threat intelligence and implementing advanced detection and response mechanisms can help identify and mitigate emerging threats before they cause extensive damage.

Government Regulations and International Cooperation

Governments worldwide should prioritize the development of comprehensive cybersecurity regulations and foster international cooperation to combat cross-border cybercrime. Strengthening legal frameworks and establishing strong partnerships between law enforcement agencies and international cybersecurity organizations will enhance the collective ability to investigate, apprehend, and prosecute cybercriminals involved in campaigns like Xenomorph.
