Using Zip Bombs to Defend Servers from Malicious Web Bots

The article describes using zip bombs—small compressed files that expand into large sizes—to protect servers from malicious bots by crashing their processes through crafted gzip responses, exemplified by a command generating a 10GB zip bomb.

The article explains using zip bombs as a defensive technique against malicious web bots by serving compressed files that expand into large payloads, crashing the bots.
It details creating a zip bomb with the command: dd if=/dev/zero bs=1G count=10 | gzip -c > 10GB.gz, which generates a 10GB zero-byte file compressed into approximately 10MB.
The author’s server employs middleware that detects malicious requests via IP blacklisting and heuristics, serving zip bombs with headers like Content-Encoding: deflate, gzip and Content-Length to crash aggressive bots.

Linux io_uring vulnerability enables malware to bypass detection tools

A Linux security flaw allows malware to evade syscall-based antivirus detection by using io_uring, which bypasses traditional system call monitoring; ARMO’s Curing demonstrates this, prompting vendor updates and kernel disabling commands.

Researchers demonstrated a Linux security vulnerability exploiting io_uring’s bypass of syscall monitoring.
A proof-of-concept named Curing, built by ARMO, evades detection tools like Falco, Tetragon, and Microsoft Defender by operating entirely through io_uring.
The io_uring interface, introduced in Linux kernel 5.1 (2019), enables asynchronous I/O via shared ring buffers, reducing system call overhead; Google disabled it in ChromeOS and production servers after $1M in bug bounties.
