Even though the popularity of the Windows OS among average end-user systems has meant that attackers have mostly focused on developing malware for Windows systems, ELF badness is a growing concern. The colleagues over at Malware Must Die are making a huge effort to put some focus on ELF malware, their article entitled China ELF botnet malware infection & distribution scheme unleashed is just an example.
Today we are rolling out a tool to generate detailed structural information regarding ELFs. This information includes: file header specifics (ABI version, required architecture, etc.), sections, segments, shared libraries used, imported symbols, exported symbols, packers used, etc. You may take a look at this new information in the File Details tab of the following report:
Hopefully all this new information will bring some attention to malware targeting linux systems and will lead to better world-wide defenses against these threats.
