This Dangerous ‘Zip Bomb’ Can Explode 46MB File Into 4.5 Petabytes

It is possible to create ‘Zip Bomb’ — a small zip file that contains multiple layers of nested zip archives. One can say it has a malicious nature since the final unzipped version of the data could be several orders of magnitude larger than the zipped one.

Once unzipped, zip bombs can render the machine unresponsive and unavailable. Now, a researcher named David Fifield has developed the most dangerous zip bomb ever; it can cause a 46MB base file to expand into 4.5 petabytes of data.

Since Fifield’s method isn’t based on recursion, it can evade antivirus software that can detect more traditional zip bombs — making it dangerous.

This is why one should avoid downloading and opening suspicious files. You’d think that this is common knowledge but the fact is a lot of people fall victim to such malacious files.
