Malware Abuses Windows Atom Tables for Novel Code Injection Technique

Security researchers from enSilo have uncovered a new technique leveraged by malware authors to inject malicious code into legitimate processes and help malware bypass security solutions.

The technique, named AtomBombinb, revolves around atom tables, a feature of the Windows operating system. Microsoft describes atom tables as such:

[CITATION]An atom table is a system-defined table that stores strings and corresponding identifiers. An application places a string in an atom table and receives a 16-bit integer, called an atom, that can be used to access the string. A string that has been placed in an atom table is called an atom name.[/CITATION]

Basically, these are shared tables where apps store information on strings, objects, and other types of data, which they need to access on a regular basis.
