Bad actors love crises. The forced telecommuting of millions of employees (and the attendant exponential increase in use of remote access technologies), coupled with real fears and concerns regarding the spread of COVID-19, have produced a fertile environment for an increase in cyberattacks. Trend Micro reports that COVID-19 is being used in a variety of malicious campaigns including email spam, business email compromise (i.e., using stolen information to initiate fraudulent wire transfers), malware, ransomware, and malicious domains. Trend Micro estimates that nearly 66% of these attacks involve email spam.
