Phishing Campaigns Targeting Google and Yahoo Accounts To Bypassing Two-Factor Authentication

Several phishing campaigns targeting hundreds of individuals across the Middle East and North Africa. The attacker targers HRDs, journalists, political actors.

Amnesty International published a report on multiple campaigns that traget self-described “secure email” services, such as Tutanota and ProtonMail and another campaign that aimed in bypassing two-factor authentication.

Crafted Phishing Sites – Secure Email Providers

The phishing campaign primarily targeted popular secure email service providers such as Tutanota and ProtonMail.

Threat actors used a well-crafted phishing page – by obtaining the domain tutanota[.]org, whereas the original domain of the service provider is tutanota[.]com.

A phishing attack is one of the dangerous social engineering attacks that leads to capture a victim’s username and password that will get store it to an attacker machine and reuse it later.

Also, Amnesty observed that attackers registered a phishing site protonemail[.]ch that crafted like as an original valid website protonmail[.]ch. When user enters the login credentials in the fake pages, attackers steal the credentials.

Google and Yahoo – Phishing Campaigns

The targeted phishing campaign designed to bypass the two-factor authentication and the campaign likely to be from the same attacker.

Attackers used a crafted phishing Email that appeared to be from an invite to edit documents on Google Drive or an invitation for calls in Google Hangout.

“In this case, we have observed less sophisticated social engineering tricks. Most often this attacker made use of the common “security alert” scheme, which involves falsely alarming the targets with some fake notification of a potential account compromise, reads Amnesty report“

The phishing pages includes a link that redirects to a well-crafted and convincing Google phishing website that designed for making victims to reveal their two-step authentication code.

Once the victim logged with in the phishing page then they will redirected to another page that sent a 2-Step Verification code, once victims presented the 2-Step Verification code then it will present a form asking us to reset the password for our account.

After that Amnesty spotted a password change was in fact issued by Windows computer operated by the attackers, seemingly connecting from an IP address that Google geolocates within the USA.

The same with Yahoo account also who configured two-factor authentication using the phone number.
