: These archives can be as small as 45 kilobytes while containing layers of nested files that expand to 1.3 exabytes (or ~45 petabytes in some variations) of uncompressed data.
While often confused with the famous 42.zip , a common variant known as (or similar "45" named files) uses recursive compression to hide massive amounts of data in a tiny package. 45.rar
Modern security software has evolved to handle these threats: : These archives can be as small as
: Most updated antivirus programs from providers like Kaspersky and Avast can identify "archive bombs" by detecting suspicious compression ratios before they are fully unpacked. : The bomb contains multiple layers of archives
: The bomb contains multiple layers of archives. For example, one file may contain 10 archives, each of which contains another 10, continuing for several layers until the bottom level holds a massive file (often 1.3 GB of zeros).
