Packet Capture ( PCAP ) File Analysis Tools

PacketTotal:

                  allows you to upload a PCAP, or packet capture, file and have it automatically analyzed and parsed against BRO IDS and Suricata signatures in order to provide information on what may have been detected in the capture file.

Microsoft Message Analyzer:

 is the successor to Microsoft Network Monitor. It is helpful in capturing, displaying, and analyzing protocol messaging traffic and other system messages. It is not only an effective tool for troubleshooting network issues, but for testing and verifying protocol implementations as well.
                  




              

Message Analyzer can certainly be used to analyze .pcap files.  The tool is generic and not specific to Microsoft, but certainly more focus is put on the Windows scenarios so Microsoft related parsers are kept up to date.  However, you can analyze virtually any kind of data, going beyond network captures like EVT, ETW, CSV and many more.

COBRA - Crysis / Dharma Ransomware

COBRA CRYSIS - NEW VARIANT OF RANSOMWARE

New variant of the Crysis / Dharma ransomware that adds the .cobra extension to the encrypted files

Recently, security researcher Jakub Kroustek discovered a new ransomware sample that appears to be a new variant of the ransomware Crysis that appends the .cobra extension to the file name of the encrypted file.

It is not known exactly how this variant is distributed, but in the past Crysis is normally propagated by piracy in remote desktop services and manually installs the ransomware.
When this variant of Cobra ransomware is installed, a computer will be scanned for data files and encryption of them. When you encrypt a file, an extension will be added in the .id- [id]. [E-mail] .cobra format .id- [id]. [E-mail] .cobra .id- [id]. [E-mail] .cobra . For example, a file called pepe.jpg was encrypted and the name was changed to pepe.jpg.id-BCBEF350.[Cranbery@colorendgrace.com].cobra .

 
It should be noted that this ransomware will encrypt assigned network drives and unassigned network shares. Therefore, it is important to make sure that the actions of your network are blocked so that only those who really need access have permission.
When this variant encodes a computer, it will also remove all plumes from volume snapshots on the machine so that they can not be used to recover encrypted files. It is removed by running the vssadmin delete shadows /all /quiet .
 
This ransomware will also create two different rescue notes on the infected machine. One of them is the file info.hta , which was launched by an automatic execution when a user initiates a session on the computer.


The other note is called encrypted files !!. Txt and can be found on the desktop.
Both rescue notes contain instructions to contact cranbery@colorendgrace.com in order to obtain payment instructions.
 
Finally, the ransomware will be configured to start automatically when it connects to Windows. This allows you to encrypt new files that are created since the last time executed.

It is not possible to decipher the new variant of Crysis Cobra

Unfortunately, at this time it is not possible to decrypt the files encrypted by the .cobra Crysis ransomware for free. The only way to recover the encrypted files is through a backup, or if you are unbelievably lucky, through volume snapshots. Although Crysis does not attempt to remove volume snapshots, in rare cases, ransomware infections do not do so for any reason.

How to protect yourself from the Crysis ransomware

In order to protect yourself from Crysis, or from any ransomware, it is important that you use good computer habits and security software. First and foremost, you should always have a reliable and proven backup of data that can be restored in the event of an emergency, such as an attack on the ransomware. You must also have security software that contains behavioral detections such as squared Anti-Malware, Malwarebytes, or HitmanPro

FireEye - GoCrack Password Cracking tool

FireEye - GoCrack Tool

                           FireEye's Innovation and Custom Engineering (ICE) team released a tool called GoCrack that allows red teams to efficiently manage password cracking tasks across multiple GPU servers by providing an easy-to-use, web-based real-time UI (Below Figure shows the dashboard) to create, view, and manage tasks. Simply deploy a GoCrack server along with a worker on every GPU/CPU capable machine and the system will automatically distribute tasks across those GPU/CPU machines.


GoCrack provides APIs to manage password cracking tasks across supported cracking engines.

Prerequisites

  • Linux (Ubuntu 16.04+ although other distributions may work) or MacOS
  • Computer(s) with NVIDIA or AMD GPUs
Some use cases for a password cracking tool can include cracking passwords on exfil archives, auditing password requirements in internal tools, and offensive/defensive operations. We’re releasing GoCrack to provide another tool for distributed teams to have in their arsenal for managing password cracking and recovery tasks.

Keeping in mind the sensitivity of passwords, GoCrack includes an entitlement-based system that prevents users from accessing task data unless they are the original creator or they grant additional users to the task. Modifications to a task, viewing of cracked passwords, downloading a task file, and other sensitive actions are logged and available for auditing by administrators. Engine files (files used by the cracking engine) such as Dictionaries, Mangling Rules, etc. can be uploaded as “Shared”, which allows other users to use them in task yet do not grant them the ability to download or edit. This allows for sensitive dictionaries to be used without enabling their contents to be viewed.

GoCrack is shipping with support for hashcat v3.6+, requires no external database server (via a flat file), and includes support for both LDAP and database backed authentication. In the future, we plan on adding support for MySQL and Postgres database engines for larger deployments, ability to manage and edit files in the UI, automatic task expiration, and greater configuration of the hashcat engine. We’re shipping with Dockerfile’s to help jumpstart users with GoCrack. The server component can run on any Linux server with Docker installed. Users with NVIDIA GPUs can use NVIDIA Docker to run the worker in a container with full access to the GPUs.

GoCrack is available immediately for download along with its source code on the project's GitHub page. If you have any feature requests, questions, or bug reports, please file an issue in GitHub.
