Zip Compression Methods
The zip file is a collection of a large number of files that are compressed to transfer large amounts of data at a faster rate. There are some popular Compression Algorithms. Some of them are as follows:
- Lempel–Ziv–Welch (LZW)-This is a popular lossless compression algorithm that works on text files. This algorithm works on strings, splits the strings, and matches prefixes. Then it refers to the dictionary to encode the prefix.
- LZ77– It is the oldest compression algorithm that analyzes input data by replacing the redundant data with metadata to reduce the size.
- Lempel–Ziv–Markov chain algorithm(LZMA)– This is a popular lossless compression algorithm that makes use of Markov chains to compress data

What is a Zip Bomb and How Does it Work?
Zip Bomb is another type of malicious attack cyber threat whose aim is to disrupt the working of the systems and steal or damage data. There are various weapons available that can be used to launch such malicious acts. Some of them include computer viruses, Denial of Service (DoS) attacks, Zip Bombs, and other attack vectors.
