Running Malware Analysis Apps as Docker Containers

A new REMnux project initiative provides Docker images of Linux applications useful for malware analysis to offer investigators easier access to malware forensics tools. Docker is a platform for packaging, running and managing applications as "containers," as a lightweight alternative to full virtualization. Several application images are available as of this writing, and you can contribute your own as a way of experimenting with Docker and sharing with the community.

Kerberos in the Crosshairs: Golden Tickets, Silver Tickets, MITM, and More

It's been a rough year for Microsoft's Kerberos implementation. The culmination was last week when Microsoft announced critical vulnerability MS14-068. In short, this vulnerability allows any authenticated user to elevate their privileges to domain admin rights. The issues discussed in this article are not directly related this bug. Instead we'll focus on design and implementation weaknesses that can be exploited under certain conditions. MS14-068 is an outright bug which should be patched immediately. If you haven't patched it yet, I suggest you skip this article for now and work that issue right away. Then come back later for some more Kerberos fun!

Our red-team friends have been quite busy recently dissecting Kerberos and have uncovered some pretty concerning issues along the way. Issues, or attacks, such as the "Golden

Protecting Privileged Domain Accounts: Restricted Admin and Protected Users

It's been a while since I've written about this topic, and in that time, there have been some useful security updates provided by Microsoft, as well as some troubling developments with Microsoft's Kerberos implementation. In order to fully cover these topics, I'm going to split the discussion into two articles. This article will cover specific updates Microsoft has provided to help protect user credentials. I'll follow up next week to discuss the Kerberos issues in depth.

As a quick reminder, the major takeaway from my previous articles on this subject are that we can successfully protect our privileged domain accounts by taking these 3 steps:


  1. Avoid interactive logons to untrusted hosts

  2. Disable ...

TorrentLocker Unlocked

Guest submission byTaneli Kaivola, Patrik Nisn and Antti Nuopponen of NIXU

TorrentLocker is a new breed of ransomware that has been spreading lately. Like CryptoLocker and CryptoWall it encrypts files on a victim's machine and then demands ransom. The victim has to pay to get the decryption software that can decrypt the files.

On a recent incident response case we came across a malware program that had all the known characteristics of TorrentLocker. We started to analyze the malware to see if there was a way to get the files decrypted without paying the ransom. It is well known that some ransomwares like CryptoLocker do implement proper encryption and that it is not possible to recover the encrypted files, but on the other hand, there are also several examples of malware that
