It is still unclear how the threat actor obtained these credentials.
Businesses and C-Level executives should be highly alert since corporate email credentials are valuable for cybercriminals as they can be monetized in different ways. The compromised emails can be abused for CEO scams, also known as Business Email Compromise (BEC) scams which is on the rise globally.
The easiest way of preventing hackers from monetizing any type of stolen credentials is to use a two-step verification (2SV) or two-factor authentication (2FA) solution for your online accounts.
C-level executives are excellent targets as an attacker can maximize the return since they will likely have access to more privileged information, such as employee data and proprietary knowledge.
To proactively stay ahead of the scammers, be vigilant at all times and avoid falling prey to scams in the first place.
