Phishing Attacks Exploit Google Apps Script

Phishing Campaign Uses Trusted Platform

Phishing attacks now exploit Google Apps Script to steal login credentials. Attackers create fake login pages that look legitimate. For example, they send emails posing as invoices to trick users. These pages, hosted on Google’s trusted domain, make the scam hard to detect.

How the Attack Works

The phishing email includes a link to a fraudulent webpage. This page uses Google Apps Script to display a fake login screen. When users enter their credentials, attackers capture the data. Afterwards, victims are redirected to the real service to avoid suspicion.

Why It’s Hard to Spot

Google Apps Script runs on a trusted domain, script.google.com. This domain is often allowed by security tools. As a result, the phishing pages bypass most filters. Attackers exploit this trust to make their scams appear authentic and safe.

Flexibility for Attackers

The platform lets attackers publish scripts as public web apps. They can remotely adjust the script without resending links. For instance, they switch lures like tax notices easily. This flexibility makes the campaign efficient and harder to track.

Abuse of Legitimate Services

Google Apps Script helps users automate tasks in Google Workspace. It integrates with tools like Gmail and Drive. However, attackers misuse it to host phishing pages. This abuse of legitimate services increases the success rate of their attacks.

Growing Trend in Phishing

Phishing actors increasingly target trusted platforms for evasion. They use Google’s infrastructure to avoid detection. Consequently, this trend highlights the need for better scrutiny of cloud services. Awareness of such tactics is crucial for defense.

Preventing Phishing Attacks

To stop these phishing attacks, configure email security to flag cloud links. For example, block or scrutinize Google Apps Script URLs. Train employees to verify email links and avoid entering credentials on suspicious pages. Additionally, enable two-factor authentication to add extra protection. These steps help safeguard sensitive data.
