Summary
From April to September 2024, Netskope Threat Labs tracked a 10-fold increase in traffic to phishing pages crafted through Webflow. The campaigns target sensitive information from different crypto wallets, including Coinbase, MetaMask, Phantom, Trezor, and Bitbuy, as well as login credentials for multiple company webmail platforms, as well as Microsoft365 login credentials. The campaigns have targeted more than 120 organizations worldwide, with the majority located in North America and Asia, across multiple segments led by financial services, banking, and technology.

Crafting phishing pages with Webflow
One of the challenges in creating phishing websites is ensuring they look identical to the legitimate page.

Some phishing pages simply redirect you from this image to t
