JUST LIKE US: Hackers who work for gov seem almost... ORGANISED
Malware quartermasters dish out exploits on demand, say researchers
State-sponsored hackers are looking less like traditional hacking crews and more like military units as they share infrastructure and adopt strict hierarchies, according to new research.
Infosec firm FireEye has identified links between 11 APT campaigns, including use of the same malware tools, shared code, binaries with the same timestamps, and signed binaries with the same digital certificates.
The 11 APT campaigns targeted a wide swath of industries and appeared unrelated at first, until cyber-sleuths uncovered digital evidence linking the attacks.
The shared development and logistics operation used to support several APT actors in distinct but overlapping campaigns points to the role of a "digital quartermaster". The role of this cyber organiser is different from that occupied by exploit brokers (firms and/or individuals who discovered or re-sell security vulnerabilities and exploits), according to FireEye.
"The main difference between the quartermaster that we identified and exploit-brokers is that we have no evidence to show the quartermaster also develops exploits for known or unknown vulnerabilities," Ned Moran, a senior malware researcher from FireEye, told El Reg. "We know that the quartermaster develops custom remote access tools but we do not know if they also develop and supply operators with exploits."
The emergence of a common development and logistics centre means that attackers are adopting an industrialised approach to cyber-spying, something that defenders of trade secrets and other digital assets are facing more organised and capable adversaries.
The mission of the digital quartermaster is to supply and maintain malware tools and weapons to support cyber espionage. The digital quartermaster also might be a cyber arms dealer, a common supplier of tools used to conduct attacks and establish footholds in targeted systems. However, common features in the campaigns tied together by FireEye suggest it's more likely we're dealing with someone who works exclusively with Chinese hacking groups, rather than the hi-tech equivalent of an arms dealer prepared to supply all and sundry.
"Based on the Chinese language user interface of the 9002 Builder, the tool used to build the 9002 remote access Trojans, we believe the digital quartermaster spoke or read Chinese," Moran told El Reg. "It is also possible that the operators of the 11 different campaigns also spoke or read Chinese."
