ENISA has released the first comprehensive study on cyber Threat Intelligence Platforms (TIPs) focused on the needs of TIP users, developers, vendors and the security research community.
The study channels its efforts into identifying some of the key opportunities and limitations of existing platforms and solutions, since information exchange formats and tools remain central items on the agenda of the cybersecurity community in general, and particularly of incident responders.

CrySyS Lab has provided a great document on its analysis on NSA’s perspective on the APT landscape. The analysis is based on Shadow Brokers leak (“Lost in Translation” leak) and most specifically on the module called “Territorial Dispute“. The purpose of this module is to detect presence of competing state intelligence services. NSA wanted to secure its operations, avoid any conflict between “Five Eyes” group as well as get intelligence on the targets of the competing state intelligence services.
See below some interesting points related to the analysis done by CrySyS Lab:

It is a fact that security controls and detection capabilities against Powershell attacks have been improved during the last years. However, are Powershell attacks still evolving?
Recently, we have read quite a few articles regarding Offensive Powershell:

This blog post from CrowdStrike provides some good information related to the persistence mechanisms used by WannaMine cryptomining worm. According to the post, WannaMine employs “living off the land” techniques such as Windows Management Instrumentation (WMI) permanent event subscriptions as a persistence mechanism. It is really interesting that crypto mining malware adapt so quickly their TTPs and use techniques that are mostly used by APT groups.

European Union Agency for Network and Information Security (ENISA) has recently released the report on Tools and Methodologies to Support Cooperation between CSIRTs and Law Enforcement.
The report aims to support the cooperation between CSIRTs – in particular national/governmental CSIRTs – and LEAs in their fight against cybercrime, by providing information on the framework and on the technical aspects of the cooperation, identifying current shortcomings, and formulating and proposing recommendations on technical aspects to enhance the cooperation.

Vincent Yiu has tweeted some really useful red teaming tips.
- Red Tip #1: Profile your victim and use their user agent to mask your traffic. Alternatively use UA from software such as Outlook.
- Red tip #2: If the enemy SOC is using proxy logs for analysis. Guess what? It won’t log cookies or POST body content as can be sensitive.
- Red tip #3: Taking a snapshot of AD can let you browse, explore and formulate future attacks if access is lost momentarily.
- Red tip #4: consider using Office Template macros and replacing normal.dot for persistence in VDI environments.
- Red tip #5: Do a DNS lookup for terms such as intranet, sharepoint, wiki, nessus, cyberark and many others to start intel on your target.
