5 ways hackers hide their tracks 5 ways hackers hide their tracks From trusted pentesting tools to LOLBINs, attackers abuse trusted platforms and protocols to evade security controls. CISOs have an array of ever-improving tools to help spot and stop malicious activity: network monitoring tools, virus scanners, software composition analysis (SCA) tools, digital forensics and incident response (DFIR) solutions, and more. But of course, cyber security is an ongoing battle between attack and defence, and the attackers continue to pose novel challenges. Older techniques, such as steganography the art of hiding information including malicious payloads in otherwise benign files, such as images are evolving, leading to new possibilities. For example, recently a researcher demonstrated even Twitter wasn’t immune to steganography, and images on the platform could be abused to pack ZIP archives of up to 3MB within them.

Metasploit remains popular today among good and bad hackers, but another red-team tool, Cobalt Strike, is increasingly playing a major role in attacks. Attackers are weaponizing the tool for the second stage of attacks to carry payloads (including Metasploit exploits) once they have penetrated the victim s network using customized, cloned, or even purchased versions of Cobalt Strike.
