Coronavirus drives new cyber crimes
The World Health Organization released an advisory warning of different cybercriminal activities involving the outbreak of COVID-19. Besides phishing and social engineering scams, there is a considerable threat of misinformation and online stores selling fraudulent or counterfeit goods. Phishing scams include the distribution of malicious email attachments disgusted as real-time maps of virus spreading, official correspondence, or documents of any global healthcare organization such as WHO. For instance, the UK's National Fraud Intelligence Bureau (NFIB) reported over 21 cases of COVID-19-related fraud schemes.
