The activity of the QBot (also known as Quakbot) banking trojan is spiking again, and analysts from multiple security research firms attribute this to the rise of Squirrelwaffle.

Squirrelwaffle emerged last month as one of the most likely candidates to fill the void left by the take-down of Emotet, and unfortunately, these predictions are quickly being confirmed.

Researchers at TrendMicro have observed a new distribution campaign for QBot relying on Visual Basic Macros (VBA) macros in Microsoft Word documents sent as attachments in phishing emails.

Previous Qbot campaigns used Excel macros, which are still present in some cases, even if they are more scarce now.
