If the attacker could establish a backdoor into the companies systems while the unsuspecting target browsed through the files. What would happen and how this information could be used against someone?

If the attacker successfully establishes a backdoor into the company's systems while the target is browsing through files, they would have unauthorized access to sensitive information and potentially be able to steal or manipulate data. This could lead to a data breach, financial loss, damage to the company's reputation, and potential legal consequences. The attacker could also install malware or ransomware, disrupt operations, or use the compromised system as a launching pad for further attacks. It is crucial for companies to have robust cybersecurity measures in place to prevent such incidents from occurring.
