The botnet – which Cloudflare calls Mantis and which is called after the small, razor-legged prawn – generated a brief however record-breaking DDoS assault in June that peaked at 26 million HTTPS requests per second (rps).
The Mantis botnet has hijacked digital machines and servers hosted by cloud firms quite than counting on low-bandwidth Web of Issues (IoT) units.

Cloudflare argues Mantis is the subsequent evolution of the Meris botnet, which relied on IoT units like compromised MikroTik routers to assault widespread web sites. Hundreds of of MikroTik routers had been hacked in 2018 and utilized in DDoS assaults via to 2021.
“Equally, the Mantis botnet operates a small fleet of roughly 5,000 bots, however with them can generate an enormous pressure – answerable for the biggest HTTP DDoS assaults we’ve got ever noticed,” Cloudflare stated.
HTTPS DDoS assaults are extra computationally costly for the attacker and sufferer attributable to the price of establishing an encrypted transport layer safety (TLS) connection over the web, in accordance with Cloudflare.
“Mantis has branched out to incorporate quite a lot of VM platforms and helps working numerous HTTP proxies to launch assaults,” Cloudflare notes.
“The title Mantis was chosen to be just like “Meris” to mirror its origin, and likewise as a result of this evolution hits laborious and quick. Over the previous few weeks, Mantis has been particularly energetic directing its strengths in the direction of nearly 1,000 Cloudflare prospects.”
Previously month, Mantis has launched over 3,000 HTTP DDoS assaults towards Cloudflare prospects, with 36% of the assaults focusing on prospects within the web and telco sector. Different widespread targets had been information organizations and video games publishers, however it additionally focused web sites of organizations in finance, e-commerce and playing.
Over 20% of the assaults focused US organizations and over 15% of assaults focused Russia-based organizations.
