In the last few years, APT attacks conducted by individual cybercriminals, organized crime and state-sponsored groups have become prevalent and sophisticated, bypassing standard security controls such as. The malware created new registry files and deployed anti-analysis techniques, including avoidance of machine detection and sandbox detection, and an anti-debug code. This requires a proactive approach that will contribute to preventing cybercrime damage that is currently estimated by Forbes to reach $2 trillion annually by 2019. Advanced persistent threats are difficult to detect, as one of the objectives of the cybercriminals is to remain in a system for an extended period to carry on the task of data exfiltration until their goal is fulfilled. An advanced persistent threat (APT) is a stealthy threat actor, typically a nation state or state-sponsored group, which gains unauthorized access to a computer network and remains undetected for an extended period. In recent times, the term may also refer to non-state-sponsored groups conducting large-scale targeted intrusions for specific goals. And since their attack techniques are so different from those used in other types of cyber attacks, they’re also marked by different indicators of compromise (IoC). Endpoint security is considered an important part of an APT security strategy. It is not meant to purely describe Chinese threat actors rather, an APT can be initiated from anywhere in the world. If this DNS tunnel is not available to communicate with the C2 server, the Trojan went on to execute its "x_mode", using Google Drive as an alternative file server.
