Déjame recordarte que SharkBot was previously reported por NCC Group expertos. They said that malware usually disguises itself as antiviruses, actually stealing money from users that installed the application. SharkBot, like its counterparts El troyano bancario TeaBot fue encontrado nuevamente en Google Play Store, FluBot, y Oscorp (UBEL), belongs to the category of banking Trojans capable of stealing credentials from hacked devices and bypassing multi-factor authentication mechanisms. The malware first appeared on the scene in the fall of 2021.

The NCC Group report emphasized that SharkBot’s hallmark is its ability to perform unauthorized transactions through Automatic Transfer System (ATS) sistemas, cuales, por ejemplo, distinguishes it from TeaBot, which requires interaction with a live operator for performing malicious actions.

Y también, por ejemplo, Cleafy y ThreatFabric dice, that the Android Trojan SharkBot uses the Accessibility service to steal credentials from banking and cryptocurrency applications in Italy, el Reino Unido y los Estados Unidos.

Ahora, Punto de control specialists have supplemented the analysis of NCC Group and their colleagues from Cleafy with new data. They write that the malware, again seen in the Google Tienda de juegos, does not infect users from China, India, Romania, Russia, Ukraine and Belarus. Al mismo tiempo, six malicious applications found by researchers were installed more than 15,000 times before being removed, and most of the victims were in Italy and the UK.

They also noticed that SharkBot has a very unusual self-distributing mechanism: it is able to automatically respond to notifications from Facebook Messenger and WhatsApp, distributing malicious links to its fake antivirus applications among the victim’s contacts.

Separately, it is noted that the malware uses DGA (Domain generation algorithm) to communicate with its control servers, which is quite rare among malwares for Android.
