Operations performed | 2010 | Operation “Iron Tiger” Operation Iron Tiger is a targeted attack campaign discovered to have stolen trillions of data from defense contractors in the US, including stolen emails, intellectual property, strategic planning documents – data and records that could be used to destabilize an organization. <https://github.com/CyberMonitor/APT_CyberCriminal_Campagin_Collections/blob/master/2015/2015.09.17.Operation_Iron_Tiger/wp-operation-iron-tiger.pdf> |
2015 | Penetration of networks for industrial espionage Designated as Threat Group 3390 and nicknamed “Emissary Panda” by researchers, the hacking group has compromised victims’ networks largely through “watering hole” attacks launched from over 100 compromised legitimate websites, sites picked because they were known to be frequented by those targeted in the attack. <https://arstechnica.com/information-technology/2015/08/newly-discovered-chinese-hacking-group-hacked-100-websites-to-use-as-watering-holes/> | |
Jul 2017 | Operation “PZChao” The past few years have seen high-profile cyber-attacks shift to damaging the targets’ digital infrastructures to stealing highly sensitive data, silently monitoring the victim and constantly laying the ground for a new wave of attacks. This is also the case of a custom-built piece of malware that we have been monitoring for several months as it wrought havoc in Asia. Our threat intelligence systems picked up the first indicators of compromise in July last year, and we have kept an eye on the threat ever since. <https://labs.bitdefender.com/2018/02/operation-pzchao-a-possible-return-of-the-iron-tiger-apt/> | |
Mar 2018 | Campaign targeting a national data center in the Central Asia The choice of target made this campaign especially significant – it meant the attackers gained access to a wide range of government resources at one fell swoop. We believe this access was abused, for example, by inserting malicious scripts in the country’s official websites in order to conduct watering hole attacks. <https://securelist.com/luckymouse-hits-national-data-center/86083/> | |
Apr 2018 | Operation “SpoiledLegacy” We have been monitoring a campaign targeting Vietnamese government and diplomatic entities abroad since at least April 2018. <https://securelist.com/apt-trends-report-q1-2019/90643/> | |
Apr 2019 | In April 2019, Unit 42 observed the Emissary Panda (AKA APT27, TG-3390, Bronze Union, Lucky Mouse) threat group installing webshells on Sharepoint servers to compromise Government Organizations of two different countries in the Middle East. <https://unit42.paloaltonetworks.com/emissary-panda-attacks-middle-east-government-sharepoint-servers/> | |
