Summary from the TLDR Web Dev newsletter

Proofpoint observed an increase in malware delivery through the abuse of Cloudflare Tunnels, particularly with the TryCloudflare feature. The campaign delivers remote access trojans (RATs) and has been evolving to bypass detection. It involves sending malicious emails with URLs or attachments, leading to the download and installation of malware like Xworm, AsyncRAT, VenomRAT, GuLoader, and Remcos.
