"Previous versions of this malware (or possibly a direct ancestor) are called “Qulab Stealer”."


"The Masad Stealer is written in Autoit scripts and is compiled into a Windows executable. The size of most of the samples analyzed by the experts was about 1.5 MiB, but experts revealed that it is possible to find larger executables bundled into other applications." "The malware achieves persistence by creating a scheduled task on all Windows devices it manages."


"Based on our telemetry, Masad Stealer’s main distribution vectors are masquerading as a legitimate tool or bundling themselves into third party tools. Threat actors achieve end user downloads by advertising in forums, on third party download sites or on file sharing sites." "[B]rowser information, and cryptocurrency wallet data from infected computers get sent back to its masters using Telegram as a communication channel."

"Threat actors achieve end user downloads by advertising in forums, on third party download sites or on file sharing sites." "Victims can also get infected when installing various software and game cracks, cheats, and aimbots, which shows that the actors behind this malware don't mind adopting very well known infection vectors that have proven to be highly effective."


"Of the more than 1,000 samples we identified to be variants of this malware, there where 338 unique Telegram Command and Control bot IDs. From this data, we can estimate the number of threat actors – or at least the number of different campaigns being run using the Masad Stealer malware – and the size of their operations. We used the getMe API, along with the bot token, to identify the usernames."

Masad Clipper and Stealer is a new form of malware which can be obtained through a malicious download. The software can obtain inforamtion about installed cryptocurrency wallets and also modify addresses in the clipboard to intercept funds.
