Attack sequences mounted by the team usually use spear-phishing e-mails and pretend social credentials to entice targets into putting in malware on their gadgets.
The most modern attacks in depth by Symantec entail the use of up to date versions of its tailor made Micropsia and Arid Gopher implants to breach targets ahead of partaking in credential theft and exfiltration of stolen knowledge.
