New Octo2 Android Banking Trojan Emerges with Machine Takeover Capabilities
Cybersecurity researchers have found a brand new model of an Android banking trojan known as Octo that comes with improved capabilities to conduct machine takeover (DTO) and carry out fraudulent transactions.
The brand new model has been codenamed Octo2 by the malware writer, Dutch safety agency ThreatFabric stated in a report shared with The Hacker Information, including campaigns distributing the malware have been noticed in European international locations like Italy, Poland, Moldova, and Hungary.
“The malware builders took actions to extend the steadiness of the distant actions capabilities wanted for Machine Takeover assaults,” the corporate said.

It has been assessed to be a “direct descendant” of the Exobot malware initially detected in 2016, which additionally spawned one other variant dubbed Coper in 2021.
“Primarily based on the supply code of the banking Trojan Marcher, Exobot was maintained till 2018 focusing on monetary establishments with a wide range of campaigns centered on Turkey, France and Germany in addition to Australia, Thailand and Japan,” ThreatFabric famous on the time.
