Infinite.zip [UPDATED]

It relies on recursive compression —layers upon layers of nested ZIP files. A single file might contain 100 zip files, each containing 100 more, and so on. 2. How it Works (The Mechanics)

Here is a deep report on its mechanics, purpose, and mitigation: 1. What is it? Infinite.zip

Do not extract unknown or unexpectedly small zip files from untrusted sources. zip and recursive zip bombs ? 42.zip (2004) - Hacker News It relies on recursive compression —layers upon layers

When an antivirus scanner or user unzips the file, the decompression engine attempts to expand every layer, leading to an exponential increase in disk space usage. 3. Purpose and Impact How it Works (The Mechanics) Here is a

Systems should be configured to reject archives where the ratio of compressed-to-uncompressed size is suspiciously high.

"Infinite.zip"—often referred to in technical circles as a type of or decompression bomb (such as the famous 42.zip )—is a maliciously crafted archive file designed to crash, freeze, or overwhelm the storage capacity of any system that attempts to unpack it.

The ZIP algorithm can compress repetitive data (like a file filled entirely with zeros) extremely efficiently. A 10 GB file of zeros can be compressed into a few megabytes.
