There are many ways you can be victimized by cybercriminals. Currently, we are seeing attackers use this MFA attack on their victims. Read more below on how this works and what you can do to protect yourself.

MFA Attack

Always remember, there are many ways you can be become victimized, this is one of many ways attackers target their victims.

The attack starts with a text, email or phone call to the victim impersonating the victim’s bank. The content of the message implies that there will be further communication needed from the victim about their account. The victim believes the communication is from their bank. In the meantime, everything is functioning normally.

Next, the attacker calls, texts or instant messages the victim to get their MFA 2 factor code when signing in to their account. The attacker references the content of the first message to the victim and simply asks for the code that is sent to the victim. The victim, believing this is legitimate, due to the first communication, provides the attacker with the code.

What happened?

The victim, believing they were talking to their bank provided their MFA code, unique to only them, and allowed the attacker to login using the victim’s username and password. The attacker already had the username and password but did not have the unique one time code. Thus, the attacker had to cleverly find a way to get the victim to provide it. How? The attacker had to first plant a seed with the victim, indicating that further communication would be coming. The victim, believed the first message, because it did not ask for anything, and therefore believed the further communications when the attacker sent them. The victim had trust for the first and later messages.
