The Icefog APT: A Tale of Cloak and Three Daggers
The emergence of small groups of cyber-mercenaries available for hire to perform surgical hit and run operations.
The world of Advanced Persistent Threats (APTs) is well known. Skilled adversaries compromising high-profile victims and stealthily exfiltrating valuable data over the course of many years. Such teams sometimes count tens or even hundreds of people, going through terabytes or even petabytes of exfiltrated data.
Although there has been an increasing focus on attribution and pinpointing the sources of these attacks, not much is known about a new emerging trend: the smaller hit-and-run gangs that are going after the supply chain and compromising targets with surgical precision.
Since 2011 we have been tracking a series of attacks that we link to a threat actor called ‘Icefog’. We believe this is a relatively small group of attackers that are going after the supply chain — targeting government institutions, military contractors, maritime and ship-building groups, telecom operators, satellite operators, industrial and high technology companies and mass media, mainly in South Korea and Japan.
