An open source adversary-in-the-middle phishing kit has found a number of takers in the cybercrime world for its ability to orchestrate attacks at scale.

DEV-1101, per the tech giant, is said to be the party behind several phishing kits that can be purchased or rented by other criminal actors, thereby reducing the effort and resources required to launch a phishing campaign.

"The availability of such phishing kits for purchase by attackers is part of the industrialization of the cybercriminal economy and lowers the barrier of entry for cybercrime," Microsoft said in a technical report.

The open source kit from DEV-1101 comes with features that make it possible to set up phishing landing pages mimicking Microsoft Office and Outlook, not to mention manage campaigns from mobile devices and even use CAPTCHA checks to evade detection.

Microsoft said it has detected numerous high-volume phishing campaigns spanning millions of phishing emails per day from various actors that leverage the tool.

"Inserting a CAPTCHA page into the phishing sequence could make it more difficult for automated systems to reach the final phishing page, while a human could easily click through to the next page," Microsoft said.
