With the upcoming releases customers with commercial licenses for Cerbero Suite Advanced and Cerbero Engine can verify Microsoft Authenticode signatures on Linux and macOS. Our Authenticode support includes full-chain certificate and time-stamp verification.
In conjunction with our recently extended support for certificate file formats, this provides complete support for inspecting signed Portable Executable binaries.
The only required step to verify Authenticode signatures on non-Windows systems is to install our “Microsoft Authenticode” package from Cerbero Store.
Cerbero Suite has been using its own implementation of Microsoft Authenticode for performance reasons since the very beginning, back in 2012. However, thanks to the recently introduced Cerbero Store we can now offer this feature on systems other than Windows.
We have also exposed Authenticode validation to our Python SDK.

Alternatively, scan hooking extensions can check the generated report for the validation scan entries.
We have just released our String Decrypter package on Cerbero Store for all licenses of Cerbero Suite. The String Decrypter package is very useful for reversing malware and during CTFs.
This utility can be invoked as an action from a hex view or a Carbon disassembly. It can be used to brute-force the decryption of strings and byte-arrays.
String Decrypter supports various types of string encodings combined with endianness and it can filter decoded strings with the following options:
– Don’t filter (include raw byte-arrays)
– Include only decoded strings
– Include only strings with ASCII characters
– Include only string matching a regular expression provided by the user
The plugin supports parallel execution, which will make the difference if more algorithms are added to the list. Also, for every decryption method the number of combinations is displayed.
For every decrypted entry, String Decrypter shows the performed operation along with the string encoding (if available).
We moved our built-in password brute-forcers to an external package on Cerbero Store called “Common Passwords”. The upcoming version 5.4 Cerbero Suite Advanced (both commercial and non-commercial) and the version 2.4 of Cerbero Engine will have access to the package.
There are two reasons why we created a standalone package:
1) We wanted to provide the same functionality to Cerbero Engine.
2) We intend to expand on the functionality of this package in the future, so making it easy to update was essential.
To obtain the package just open Cerbero Store and install it from there.
Only the default passwords key provider is enabled by default. Other key providers must be enabled manually.
This is a very practical package if you want to avoid typing usual passwords like “password” or “infected”. These are considered default passwords and just installing the package will have you covered.
