A report out today from SlashNext Inc. details a new phishing kit being advertised on dark web forums that significantly lowers the barriers for cybercriminals to launch effective phishing attacks.

Advertised under the name of FishXProxy, the phishing kit equips cybercriminals with a formidable arsenal for multi-layered email phishing attacks. It includes features such as uniquely generated links and dynamic attachments to bypass initial scrutiny, advanced antibot systems using Cloudflare Inc.’s CAPTCHA, and a clever redirection system that obscures true destinations.

According to the report, FishXProxy’s sophisticated approach and easy-to-use interface make it accessible even to those with minimal technical skills, significantly increasing the potential for successful phishing campaigns.

The advanced antibot system in FishXProxy offers multiple configurations, including internet protocol reputation checks and CAPTCHA challenges, to filter out automated scanners and security researchers. The system ensures that only genuine targets are presented with the phishing content, improving the chances of capturing sensitive information.

Integration with Cloudflare’s infrastructure is said to provide phishing operators with robust performance and security features. FishXProxy leverages Cloudflare Workers and SSL certificates to distribute phishing logic across an edge network to present phishing sites with a legitimate appearance.

The built-in redirector and page expiration settings offered in the phishing kit enhance its effectiveness by hiding the true destination of phishing links. It also automatically expires phishing pages, making it difficult for security teams to detect and analyze the attacks in time.

SlashNext warns that FishXProxy’s ease of use and comprehensive features represent a significant threat to online security. Security teams and organizations are being urged to implement advanced security measures and educate employees on recognizing phishing attempts to mitigate the risks posed by such sophisticated phishing kits.

Mika Aalto, co-founder and chief executive officer at human risk management platform company HoxHunt Oy, told SiliconANGLE that “phishing kits are lowering the barrier of entry to advanced cybercrime even for low-resourced and not terribly clever criminals.”

“As more phishing attacks consequently bypass filters, we need to make sure our people are equipped with the skills and tools to keep themselves and their colleagues safe,” Aalto added. “Even advanced attacks will trigger a mental alarm in the upskilled human defense layer.”
