Researchers at CSE Cybsec ZLab analyzed shared published their analysis of the Telegram-based Android RAT tracked as HeroRAT.
In June, researchers from security firm ESET discovered a new family of Android Remote Administration Tool (RAT), dubbed HeroRAT, that leverages the Telegram BOT API to communicate with the attacker.
The use of Telegram API can be considered a new trend in Android RAT landscape, because other RAT families implementing the same functionalities, such as TeleRAT and IRRAT, were discovered in the wild before HeroRAT.
HeroRAT appeared very active in Iran where it was spreading through third-party app stores, through tainted social media and messaging apps.
ESET experts speculate that the HeroRAT borrows the source code of a malware appeared in the hacking community in March 2018, however, it has some characteristics that distinguish it different from IRRAT and TeleRAT. One of these features is the usage of the Xamarin Framework and TeleSharp Library for the development of the RAT.
HeroRAT is offered for sale on a dedicated Telegram channel, the author offers three different variants depending on its functionalities: bronze (25 USD), silver (50 USD) and gold panels (100 USD). The malware author also released a demo video in which explains the RAT functionalities; below we have a screenshot from this demo video, showing the differences between the three variants.
