Also earlier this week, McAfee released a report that just about everyone in the security industry has likely now read, “Revealed: Operation Shady RAT”. The report, written by Dmitri Alperovitch, VP Threat Research at McAfee, is an eye opening read covering targeted intrusions into over 70 global companies, governments and non-profit organizations over the last 5 years. The report covers the types of organizations hit the hardest (not shockingly, defense contractors led the list with 13 of the intrusions detected), the ramifications of the breaches, estimated times each were compromised (shortest being 1 month, an honor shared by 9 victims) and even outlines the generic attack approaches utilized:“While no single strategy can prevent this type of malicious activity, the effectiveness of implementing the top four strategies remains unchanged. Implemented as a package, these strategies would have prevented at least 70% of the intrusions that DSD analysed and responded to in 2009, and at least 85% of the intrusions responded to in 2010.”
(Side note: Not to be outdone, Symantec did their own analysis of the attacks, which adds even more details. You can find that analysis here.)The compromises themselves were standard procedure for these types of targeted intrusions: a spear-phishing email containing an exploit is sent to an individual with the right level of access at the company, and the exploit when opened on an unpatched system will trigger a download of the implant malware. That malware will execute and initiate a backdoor communication channel to the Command & Control web server and interpret the instructions encoded in the hidden comments embedded in the webpage code. This will be quickly followed by live intruders jumping on to the infected machine and proceeding to quickly escalate privileges and move laterally within the organization to establish new persistent footholds via additional compromised machines running implant malware, as well as targeting for quick exfiltration the key data they came for.
In short, the McAfee report does an excellent job of driving home Dmitri’s (and most security professionals’) key message:
Which finally brings me to the objective of this post. This is an Open Letter to McAfee, Symantec and the Australian DoD. Let’s find a way of making the “Operation Shady RAT” project truly useful. Please combine the known attacks from “Operation Shady RAT” with the best practice mitigation methodology utilized by the DoD in creating their 35 mitigation recommendations. Truly analyze the security processes and procedures that were in place at each victim, perhaps categorized by their effectiveness in shortening or avoiding the breach (I have to believe that the 9 entities that had the shortest compromises were doing something different than the ones that remained compromised for years), and create a modified (if necessary) version of the DoD’s mitigation recommendations. That would be truly useful… beyond the BFO (blinding flash of the obvious) from the original report: That all entities with any valuable infrastructure or information fit “into two categories: those that know they’ve been compromised and those that don’t yet know.“I am convinced that every company in every conceivable industry with significant size and valuable intellectual property and trade secrets has been compromised (or will be shortly), with the great majority of the victims rarely discovering the intrusion or its impact. In fact, I divide the entire set of Fortune Global 2000 firms into two categories: those that know they’ve been compromised and those that don’t yet know.”
