Kaspersky researchers recently uncovered a new malicious WhatsApp spy mod, which is now proliferating within another popular messenger, Telegram.
While the modification serves its intended purpose by extending user experience, it also clandestinely harvests personal information from its victims, as indicated in a Kaspersky report recently. With an extensive reach surpassing 340,000 in just one month, this malware predominantly targets users who communicate in Arabic and Azeri, though victims have been identified globally.
Users often turn to third-party mods for popular messaging apps to add extra features. However, some of these mods, while enhancing functionality, also come with hidden malware. Kaspersky has identified a new WhatsApp mod offering not only additions like scheduled messages and customizable options, but it also contains a malicious spyware module.
The modified WhatsApp client’s manifest file includes suspicious components (a service and a broadcast receiver) not present in the original version. The receiver initiates a service, launching the spy module when the phone is powered on or charging. Once activated, the malicious implant sends a request with device information to the attacker’s server. This data covers IMEI, phone number, country and network codes, and more. It also transmits victim’s contacts and account details every five minutes as well as able to set up microphone recordings and exfiltrate files from external storage.
Kaspersky Researchers Alerted Telegram
The malicious version found its way through popular Telegram channels, predominantly targeting Arabic and Azeri speakers, with some of these channels boasting nearly two million subscribers. Kaspersky researchers alerted Telegram about the issue. Kaspersky’s telemetry identified over 340,000 attacks involving this mod in just October. This threat emerged relatively recently, becoming active in mid-August 2023.
Azerbaijan, Saudi Arabia, Yemen, Turkey, and Egypt witnessed the highest attack rates. While the preference leans towards Arabic and Azerbaijani-speaking users, it also impacts individuals from the US, Russia, UK, Germany and beyond.
Kaspersky products detect the Trojan with the following verdict Trojan-Spy.AndroidOS.CanesSpy.
“People naturally trust apps from highly followed sources, but fraudsters exploit this trust. The spread of malicious mods through popular third-party platforms highlights the importance of using official IM clients. However, if you need some extra features not presented in the original client, you should consider employing reputable security solution before installing third-party software, as it will protect your data from being compromised. For robust personal data protection, always download apps from official app stores or official websites,” comments Dmitry Kalinin, security expert at Kaspersky.
Recommendations
To stay safe, Kaspersky experts recommend:
- Use Official Marketplaces: Download apps and software from reputable and official sources. Avoid third-party app stores, as the risk thet may host malicious or compromised apps is higher.
- Use reputable security software: Install and maintain reputable antivirus and anti-malware software on your devices. Regularly scan your devices for potential threats and keep your security software up to date.
- Educate yourself about common scams: Stay informed about the latest cyber threats, techniques, and tactics. Be cautious of unsolicited requests, suspicious offers, or urgent demands for personal or financial information.
- Third-party software from popular sources often comes with zero warranty. Keep in mind that such apps can contain malicious implants, e.g. because of supply chain attacks.
