Multi-factor authentication (MFA) is a safety measure used to protect against hackers and cyber criminals. MFA works by sending a one-time code to your phone or chosen MFA app when you try to log into an account. In an MFA prompt bombing attack, a hacker will repeatedly send MFA requests to your device with the hope of eventually tricking you into approving one. If you click on the fake link just once, the hacker is already in the account and able access sensitive business data.
There are a few things you can do to protect yourself from MFA prompt bombing attacks:
- Never click “Accept” or “Approve login” unless you are absolutely sure it is legitimate.
- If you are unsure about an MFA request, contact the company or organization that owns the account and ask them if the request is legitimate.
- Change your password for any affected accounts.
- Check if your platform supports Geographical Login Restrictions, which can help protect you from MFA prompt bombing attacks launched from other countries.
What is an MFA Prompt Bombing Attack?
An MFA prompt bombing attack is when a hacker repeatedly sends MFA requests in an attempt to trick you into approving one of them. If you click on the fake link just once, they are already in the account and have access to sensitive business data. MFA works by sending a one-time code to your phone or chosen MFA app when you try to log into an account. This code needs to be entered in addition to your username and password, and it changes every time you try to log in.
The problem with MFA is that it can be vulnerable to attack if not implemented correctly. In an MFA prompt bombing attack, also known as an SMS flooding attack, the hacker sends so many requests that it overloads your device with notifications. The goal is to eventually trick you into approving one of the requests without realizing it’s fake. Once they have access to your account, they can do anything they want with it – including stealing sensitive business data.
MFA prompt bombing attacks are becoming increasingly common as hackers look for new ways to gain access to sensitive business data. However, there are a few things you can do to protect yourself from these types of attacks, including never clicking “Accept” or “Approve login” unless you are absolutely sure it is legitimate and changing your password for any affected accounts as soon as possible after an attack takes place. Geographical Login Restrictions can also help protect you by only allowing logins from certain locations. Implement these measures today to help keep your business safe from MFA prompt bombing attacks tomorrow!
