Turla is the name of a Russian cyber espionage ATP group (also known as Waterbug, Venomous Bear and KRYPTON) that has been active since at least 2007 targeting government organizations and private businesses.
The list of victims is long and includes also the Swiss defense firm RUAG and the US Central Command.

The malicious document has been sent by the Qatar ambassador’s secretary, researchers from Kaspersky speculate the cyber spies may have breached the diplomatic organization’s network.
“Based on the name of the document (National Day Reception (Dina Mersine Bosio Ambassador’s Secretary).doc, it is presumed it may have been sent from the Qatar Ambassador’s secretary to the MoFA, possibly indicating Turla already had control of at least one system within Qatar’s diplomatic network.” states the report published by Kaspersky.
“The malware is fairly simplistic but flexible in its functionality, running a standard batch of profiling commands on the victim and also allowing the actors to run arbitrary commands via Wscript.” continues the analysis.
The C&C can send arbitrary commands to the infected system using Wscript.shell.run().
Kaspersky has analyzed the malware by using the “sinkholing technique,” the researchers used as a sinkhole one of the C&C domains that had expired. In this way, the experts were able to analyze the traffic from infected systems that were contacting the C&C infrastructure. With this technique, the experts discovered that one of the victims used an IP address associated with the Greek Parliament.
Researchers from Kaspersky believe that KopiLuwak malware will be used more in the future.
“Currently, it seems the Turla actors continue to rely heavily on embedded macros in Office documents,” explained Kaspersky’s Brian Bartholomew. “While this may appear to be an elementary technique to use for such a sophisticated actor, they are repeatedly successful in compromising high value targets with this method.”
The Turla APT group continues to leverage on embedded macros in Office documents, an elementary technique that anyway allowed it to compromise high-value targets.
