What steps should I take to address the security issues related to the Instagram login?

 In the context of selenium, you can address this particular issue by using the appropriate approaches:-

Immediate Action

Notice employees

You can send an urgent communication to all the employees so that you can warn them about the phishing attempt.

You can advise those who entered their credentials to change their Instagram password and enable two-factor authentication.

Block access to the malicious site

You can update the firewall of the company and web filters to block access to “Instagram login.com”.

Long term measures

Employer training

You can conduct regular cybersecurity awareness training to educate employees on identifying phishing sites and other online threats.

Enhancing email security

You can implement advanced e-mail filtering solution to reduce the phishing email reaching employees.

Using the endpoint protection

You can deploy endpoint protection solutions to provide real-time monitoring and threat direction.

Here is an example given below of firewall rules, security configuration, and firewall setup:-
