🔥 Antivirus Bypass using Code Signing 🔥

Code signing is a method software publishers use to authenticate the programs they distribute to end-users. Basically, a code-signed program tells the end-user and an end-user’s computer that the program being installed/executed is from a legitimate software publisher.

Digitally signed malware can bypass system protection mechanisms that install or launch only programs with valid signatures

You can use the SignTool to sign file with a valid certificate Go Daddy.
For example:

signtool.exe sign /f t.iss.one_secdevoops.pfx /p "*Aspider#" /t https://timestamp.digicert.com .\yourfile
.exe

This allows you to digitally sign PE binaries such as .exe, .cab, .dll, .ocx, .msi, .xpi and .xap files.

📜 Abusing Code Signing Certificates

Abusing code signing certificates is not new. In the past few years alone, it has proven to be an effective method of bypassing certain security controls to allow malicious software to run and look seemingly benign. This article describes code signing methods, as well as tools for copying the signature from legitimate PE files.

😈 dirDevil: Hiding Code and Content Within Folder Structures

This article describes a method for hiding data within directory structures by using GUIDs in folder names to encode information. This approach bypasses AV and DLP systems since the data is stored in folder names rather than files, making it difficult to detect and analyze.
