What are the Duties of a Malware Analyst?
Security Intelligence, IBM – Jennifer Gregory
Malware analysts, sometimes called reverse engineers, are hired by companies in the cybersecurity industry that need to ensure their products detect malware. Non-cybersecurity companies may also hire malware analysts to help reduce the risk of malware attacks.

A malware analyst must be both proactive and reactive. By staying up to date on all anti-malware technology and malware strains, an analyst can determine the best way for the organization to protect itself against current malware threats. Knowledge of recent attacks and strains helps the analyst change processes and technology.

The analyst also monitors systems and codes, usually by using artificial intelligence (AI) technology, to detect malicious code. When suspected malware is discovered, the analyst assesses whether the malware is harmful or benign by monitoring how the program interacts with the environment. If the malware is malicious, the analyst works to remove the code and help repair any damage. Malware analysts also write documentation about specific malware and processes for preventing future attacks.
