An advanced cyber-espionage network targeting high-profile organizations and governments has recently been unveiled. The main attack method being used in this campaign is spear phishing.

This exploit is also blocked by our Intrusion Prevention Signatures:

Initially, samples of this malware were being detecting as Backdoor.Trojan. We have since broken out the following additional specific detections:

Figure 1. Backdoor.Rocra distribution

This is not the first time that a high-profile attack campaign has used spear phishing emails and, as a popular method, it likely will not be the last . However, we are now seeing increased adoption of watering hole attacks being used in campaigns (compromising certain websites likely to be visited by the target organization). For more information on watering hole attacks, read our paper on The Elderwood Project.

We advise users to ensure that operating systems and software are up to date and to avoid clicking on suspicious links and opening suspicious email attachments.
