The Roaming Mantis cyberattack campaign has gained prominence in recent times by utilizing Android malware to hijack DNS through Wi-Fi routers. This campaign primarily targets Android smartphone users in Japan, South Korea, Taiwan, France, and Germany. The malware spreads through various means such as malicious APK files disguised as legitimate apps, phishing emails, smishing messages, and malicious links. Once a device is infected, the malware proceeds to steal user credentials, device information, and financial data. Roaming Mantis employs a DNS changer technique to manipulate Wi-Fi routers and redirect DNS queries to fake landing pages. The Wroba malware is used to carry out these malicious activities, creating a network of infected devices for further exploitation. Notably, the malware can propagate to other devices on the same network, taking advantage of security vulnerabilities in public or open Wi-Fi networks. Cybersecurity professionals and researchers rely on Indicators of Compromise (IoCs) to identify infected devices and networks. To protect against such malware attacks, Android users should implement robust security measures, regularly update their devices, and exercise caution while downloading apps.

Campaign Overview
The Roaming Mantis campaign is an active cyberattack campaign that utilizes malicious APK files to gain control of Android devices, targeting users in Japan, South Korea, Taiwan, France, and Germany, and aims to steal user credentials, device information, and financial information. This campaign has had a significant impact on global cybersecurity, as it has successfully infiltrated numerous devices and compromised sensitive data. To counter the Roaming Mantis campaign, robust countermeasures are necessary. These countermeasures include implementing strong network security protocols, regularly updating and patching Android devices, and exercising caution while downloading apps. Additionally, cybersecurity professionals should stay vigilant and regularly monitor IoCs to identify and mitigate potential threats. Proactive defense measures are crucial in protecting against the Roaming Mantis campaign and safeguarding sensitive information.
Infection Flow
Initially focused on Japan, South Korea, and Taiwan, the infection flow of the Roaming Mantis campaign involves the use of malicious APK files distributed through legitimate apps and phishing emails to target Android smartphone users with financial motives. The campaign has since expanded to include France and Germany in 2022. To evade detection, the malware disguises itself as a Google Chrome app. It intrudes into devices through smishing messages and malicious links. This infection flow has had a significant impact on global cybersecurity, highlighting the need for robust measures to protect against DNS hijacking. Users should exercise caution while downloading apps and regularly update their devices to mitigate vulnerabilities. Additionally, network administrators should implement comprehensive security measures and regularly check for indicators of compromise to ensure the integrity of their networks.
DNS Hijacking
DNS hijacking is a technique employed by the Roaming Mantis campaign to manipulate Wi-Fi routers and redirect DNS queries to fake landing pages. This malicious activity has a significant impact on network infrastructure as it allows the attackers to intercept and control the flow of internet traffic. By redirecting devices to attacker-controlled web pages, the campaign can steal sensitive information, such as user credentials and financial data. To mitigate the risks associated with DNS hijacking, it is crucial to implement robust security measures. These include regularly updating and patching router firmware, using strong passwords, and enabling DNSSEC (Domain Name System Security Extensions) to ensure the authenticity and integrity of DNS responses. Additionally, network administrators should monitor DNS traffic for any suspicious activities and employ DNS filtering and monitoring solutions to detect and block malicious DNS requests.
Wroba Malware
Wroba malware is capable of executing a range of malicious activities, including targeting vulnerable routers through DNS manipulation. It plays a significant role in the Roaming Mantis campaign, as it creates a network of infected devices for further exploitation. This malware has been reported in various countries, including Austria, France, Germany, India, Japan, Malaysia, Taiwan, Turkey, and the U.S. Its presence highlights the impact on global cybersecurity, as it poses a serious threat to network security. To mitigate the risks associated with Wroba malware, detection and prevention techniques are crucial. Cybersecurity professionals and researchers rely on indicators of compromise (IoCs), such as the MD5 hash of the malware, as a unique identifier for identification and analysis. Proactive defense measures, regular updates, and patches for vulnerable devices are essential to combat the malicious activities of Wroba malware.
Network Security Checklist
To ensure a secure network infrastructure, administrators can refer to a network security checklist that provides a comprehensive framework for identifying and mitigating potential vulnerabilities. This checklist serves as a valuable resource for maintaining the integrity of Wi-Fi routers and protecting against DNS hijacking. The following best practices are recommended:
- Regular network security audits: Conducting frequent audits helps identify any weaknesses or vulnerabilities in the network and allows for timely remediation.
- Strong password protection: Implementing strong passwords for Wi-Fi routers helps prevent unauthorized access and reduces the risk of DNS hijacking.
- Firmware updates: Keeping the router’s firmware up to date ensures that any security vulnerabilities are patched and mitigated.
- DNSSEC implementation: Deploying DNS Security Extensions (DNSSEC) helps protect against DNS hijacking by ensuring the integrity and authenticity of DNS responses.
By following these best practices, administrators can enhance the security of their Wi-Fi routers and minimize the risk of DNS hijacking.
