    The COVID-19 pandemic has driven the global adoption of remote work as a new, potentially transformative norm. But remote work also represents a golden opportunity for cybercriminals, who have found employees working from home, under loose supervision, to be soft targets for hacking. Hackers are using increasingly novel, sophisticated tools. But more mundane exploits, including oldschool malware and socialengineeringmethodssuch as phishing and vishing, are seeing a resurgence as remote employees or contractorspreoccupied with work and inexpert in cybersecurityprove vulnerable.

    Remote employees are soft targets for hackers and cyberspies.

    Mid-level employees have difficulty thinking of themselves as targets for industrial spies or state-sponsored cyberspies. Construction firms have also been targeted by hacks and ransomware attacks. The manufacturing industry, long considered lax in its cybersecurity standards in comparison to other industries, had by 2020 become the second-most targeted industry for ransomware and data-theft exploits, after financial services.
