Kaspersky Lab’s team of experts published a new research report about NetTraveler, which is a family of malicious programs used by APT actors to successfully compromise more than 350 high-profile victims in 40 countries. The NetTraveler group has infected victims across multiple establishments in both the public and private sector including government institutions, embassies, the oil and gas industry, research centers, military contractors and activists.
According to Kaspersky Lab’s report, this threat actor has been active since as early as 2004; however, the highest volume of activity occurred from 2010 – 2013. Most recently, the NetTraveler group’s main domains of interest for cyberespionage activities include space exploration, nanotechnology, energy production, nuclear power, lasers, medicine and communications.
During Kaspersky Lab’s analysis, its team of experts obtained infection logs from several of NetTraveler’s command and control servers (C&C). C&C servers are used to install additional malware on infected machines and exfiltrate stolen data. Kaspersky Lab’s experts calculated the amount of stolen data stored on NetTraveler’s C&C servers to be more than 22 gigabytes. Exfiltrated data from infected machines typically included file system listings, keyloggs, and various types of files including PDFs, excel sheets, word documents and files. In addition, the NetTraveler toolkit was able to install additional info-stealing malware as a backdoor, and it could be customized to steal other types of sensitive information such as configuration details for an application or computer-aided design files.
