A "Zip Bomb" (or decompression bomb) is a malicious archive file designed to crash or disable the reading system or antivirus scanner. While the archive file itself might be only a few megabytes, the data expands exponentially upon extraction into hundreds of gigabytes or terabytes. This overwhelms the host machine's RAM and available hard drive space, resulting in a severe Denial of Service (DoS). Safe Inspection Workflow
Cybercriminals frequently use randomized or alphanumeric file names to bypass basic email filters. The string might represent a unique victim ID, a campaign tracking number, or a timestamp (for example, 01211961 mirrors the date format January 21, 1961). If you received this file as an unexpected email attachment or downloaded it from an unfamiliar website, it is highly likely to be a trojan, ransomware, or an infostealer disguised as a document. 2.
