Zip bombs utilize two primary methods to achieve extreme compression ratios:
: If the software detects that a 1MB file is trying to expand into 1GB, it will flag the file as a "Decompression Bomb" and halt the process. nickel.zip
: If a file has 5 layers of recursion, and each layer contains 16 files, the final count of files to be processed is Zip bombs utilize two primary methods to achieve
While "nickel.zip" is a newer or alternative naming convention, it follows the lineage of the famous . If a file contains nothing but the same character (e
Compression algorithms like work by finding repetitive patterns. If a file contains nothing but the same character (e.g., the letter "a") repeated a trillion times, the algorithm can compress it down to almost nothing.
The file is structured like a "nesting doll." Inside the main ZIP file are 16 smaller ZIP files. Inside each of those are 16 more, and so on.
: By "distracting" the antivirus scanner with the massive decompression task, other real malware may sneak past the scanner while the system is bogged down. 4. Modern Defenses
