I00068 Attempted Audio Deepfake Call Targets LastPass Employee	“While reports of [...] deepfake calls targeting private companies are luckily still rare, LastPass itself experienced a deepfake attempt earlier today that we are sharing with the larger community to help raise awareness that this tactic is spreading and all companies should be on the alert. In our case, an employee received a series of calls, texts, and at least one voicemail featuring an audio deepfake from a threat actor impersonating our CEO via WhatsApp. As the attempted communication was outside of normal business communication channels and due to the employee’s suspicion regarding the presence of many of the hallmarks of a social engineering attempt (such as forced urgency), our employee rightly ignored the messages and reported the incident to our internal security team so that we could take steps to both mitigate the threat and raise awareness of the tactic both internally and externally.” In this example attackers impersonated the CEO of LastPass (T0097.100: Individual Persona, T0143.003: Impersonated Persona), targeting one of its employees over WhatsApp (T0043.001: Use Encrypted Chat Apps) using deepfaked audio (T0088.001: Develop AI-Generated Audio (Deepfakes)).
