The need for dump analysis in Cyber Threat Intelligence (CTI)

Over the last year, there have been numerous dumps of stolen classified data posted on the Internet for all to see.  The damage from these dumps has obviously been huge to the US intelligence community.  In this post, we won’t discuss the actual damage of the dumps to the intelligence community (many others have already pontificated on that).  Instead, this post will focus on the need for CTI analysts to perform analysis of the dumps.

For the first time, CTI analysts have a view of what appears to be a relatively complete nation state toolset in the Shadow Brokers dumps and insight into tool development and computer network exploitation (CNE) tool requirements in the Vault 7 dumps.  These are game changers for CTI analysts. We define threat as the intersection between intent, opportunity, and capability.  These tools and documents highlight the capabilities of an APT adversary. Whether you believe the US intelligence services have the intent to attack your network, it is likely (almost certain) that other nation state attackers have developed similar capabilities.  Analyzing the data you have available (Shadow Brokers and Vault 7) can help shed light on what you don’t have available (every other nation state attacker’s toolset in a single dump).

Note: We understand that this is a sensitive topic. When classified data is released, it is still considered classified until declassified by a classification authority.  There is no evidence that any classification authorities have declassified the data in the Shadow Brokers or Vault 7 dumps.  It is likely that they remain classified to this day.  The advice in this article may put those with security clearances at odds with the advice of their security officers.  Please proceed with care.

Software plugins/extensions should be part of your threat model

Over the last few months we’ve seen multiple cases of warnings about plugins and extensions for various software packages threatening the security of users.  We’ve recently seen the Copyfish and and Web Developer Chrome plugins compromised and used to push malware to users.

While Chrome is likely safe and should probably not be considered a threat, perhaps your plugins should be.  Plugins are developed by potentially malicious third parties. Even if your plugin developers are not themselves malicious, they have security concerns just like everyone else.  And make no mistake about it: when understanding software supply chain issues, their security is your security.

An important consideration for “bug bounty” programs

The US DoJ recently released guidance on running vulnerability disclosure programs (aka bug bounties).  The document is nothing earth shattering, but does provide some free advice to organizations considering such programs.

Rendition’s advice to organizations considering a bug bounty program? Think VERY carefully about how it will impact your monitoring and detection strategies. People looking for bugs will create noise in your network – a lot of it.  And the noise will look like attacks, because technically they ARE attacks. How will you separate this non-malicious attack traffic from real attack traffic you should be concerned about?
