Mirai Botnet’s New Wave: hailBot,kiraiBot, catDDoS, and Their Fierce Onslaught

In September 2023, NSFOCUS monitored several new botnet variants based on Mirai, namely hailBot, kiraiBot, and catDDoS, which pose a considerable threat. The hailBot spreads via vulnerability exploitation and weak password brute force, while the kiraiBot incorporates personal design elements. The catDDoS encrypts and stores key information using the ChaCha20 algorithm. Most recent botnets are derived from integrating Mirai and Gafgyt codes, aiming to enhance stealthiness and manipulate communication tactics.
