Explanation
The user has likely fallen victim to a phishing scam, which is a fraudulent attempt to obtain sensitive information, such as passwords, by disguising as a legitimate entity. The link in the email that required the user to change the account password was probably a fake website that mimicked the company's external database, and captured the user's credentials when they entered them. This could compromise the security and integrity of the company's data, as well as the user's identity and privacy12.
The company should take immediate action to prevent further damage and investigate the incident. The first step is to disable the user's account and inform the security team. Disabling the user's account can prevent unauthorized access to the external database by the attackers, who may use the stolen credentials to log in and manipulate or steal data. Informing the security team can alert them of the breach and allow them to take appropriate measures, such as scanning for malware, changing passwords, notifying other users, and reporting the incident34.

Air-gapping is a sound security strategy - but one must acknowledge both its gaps and implications on the security products you can use. Silverfort's MFA enables you to enforce secure authentication and validate the identity of users in air-gapped networks, ensuring they are protected against identity-based attacks.

The best way to protect an organization against social engineering is to provide recurring training and support.
Social engineering is a type of attack that exploits human psychology and behavior to manipulate people into divulging confidential information or performing malicious actions. Social engineering can take various forms, such as phishing emails, phone calls, impersonation, baiting, or quid pro quo. The best defense against social engineering is to educate and empower the employees to recognize and avoid common social engineering techniques and report any suspicious activities or incidents. Recurring training and support can help raise awareness and reinforce best practices among the employees.
