The United States has the highest number of malicious domains with names associated with the current coronavirus crisis, a new report reveals.
Now, Palo Alto Networks' security researchers say they have identified over 86,600 risky or malicious domains out of 1.2 million domain names registered between March 9 and April 26 that contain keywords related to the COVID-19 pandemic.
Most of the risky or malicious domains are located in the United States, followed by Italy, Germany, and Russia.
Palo Alto Networks researchers also discovered that some of the malicious domains would resolve to multiple IP addresses, while some IP addresses were being used for multiple domains.
"A blacklisted IP in a layer-3 firewall may fail to block the traffic to/from a malicious domain while unintentionally making many other benign domains unreachable."
