SANS ISC posted a diary on 9 Fast and Easy Ways To Lose Your Crypto Coins and a report on scans for Bitcoin wallet files.
This started me thinking about setting up a simple honeypot, pretending to be a self-decompressing crypto wallet archive and see if criminals would actually open that file, hoping it to be an unprotected crypto wallet.
Announce a “wallet.dat” / “wallet.zip” on public dump sites; Host the file on a public … Read more.
MISP, Malware Information Sharing Platform & Threat Sharing is a feature-rich platform for sharing threat intelligence information. You can extend MISP so that it integrates nicely with your own security solutions via the MISP module extensions. These MISP module extensions, https://github.com/MISP/misp-modules/, allow you to
extend the MISP threat intelligence sharing platform without altering the core; connect and enrich the MISP information from other information providers; get started quickly without a need to study the … Read more.
You are running a MISP instance and you want to visualize the MISP events in real-time?
MISP-Dashboard can do that! An example :

In this post I will walk you through how to setup MISP-Dashboard, based on the event data made available via botvrij.eu.
MISP-Dashboard is a new repository showing live data and statistics from the MISP ZMQ. It means you need to have MISP-ZMQ configured.
The MISP ZeroMQ plugin … Read more.

SANS has reported on different malware attacks (Hancitor and Necurs) that abuse the Microsoft Office DDE feature. Similarly, Talos also reported on a malware campaign that used the same technique to get a first foothold in an organisation (DNSMessenger).
DDE is a Microsoft feature now superseded by OLE that allows applications to share data and memory. Usage of the feature does not require a macro and will not show the user a security warning. The … Read more.
KRACKs (Key Reinstallation AttaCKs) is a number of vulnerabilities in WPA2, related to key handshakes between a client and an access point.
An attacker can trick a victim into reinstalling an already-in-use key. This key (the 3rd message in a 4-way handshake) is resent multiple times by the attacker and each time installed by the client, resetting the nonce. By forcing nonce reuse in this manner, the same encryption key is used with nonce values … Read more.
I attended SANS FOR610: Reverse-Engineering Malware instructed by Jess Garcia in Copenhagen (Sep-17). I’m now studying for certification and using captured malware samples for doing exercises. In this post I go through
Using public (OSINT) information; Behavioural analysis with sandboxes (via a public malware sandbox); Malicious Office documents.
Note that the purpose of the exercise is not to understand in detail every line of code in the malware. The analysis is done from an incident … Read more.
I published an article on IBM Security Intelligence on Basic Security Tools You Cannot Afford to Miss in Your Risk Management Program. The article covers essential, freely available, tools for doing security risk management.
I published an article on IBM Security Intelligence on Raise the Red Flag: Guidelines for Consuming and Verifying Indicators of Compromise.
The articles covers how you can consume indicators of compromise (IOC) received via manual sharing. Although automatic sharing is preferred not all organisations have the resources to setup automatic sharing. Manual sharing is then a good fallback compared to not sharing at all.
The steps include source and content verification, context verification, sharing properties, … Read more.
Mid 2014 Symantec released a report on a threat actor Dragonfly targeting energy companies. Early September 2017 Symantec released an updated report on Dragonfly v2 where they describe that the threat actor shifted their attention from merely observing the environment to having remote access to the environment of energy providers.
This shift could indicate that the threat actor has a changed objective, from monitoring to actually intervening and potentially conducting sabotage.
I created two mindmaps … Read more.
