Federal Bureau of Investigation (FBI) and Cybersecurity and Infrastructure Security Agency (CISA) issued joint advisory warning teleworkers of an ongoing vishing campaign. Vishing (also known as voice phishing) is a type of social engineering attack where the attackers impersonate a trusted entity during a voice call to manipulate their targets into revealing sensitive information. The FBI and CISA issued a joint advisory for teleworkers. The agencies said the attackers are on a very tight timeline given that they sold the stolen credentials very quickly after initially gaining access to companies’ networks.
