Google Apps Script Exploited in Wave of Sophisticated Phishing Attacks
Cybercriminals are increasingly leveraging the “Google Apps Script” advancement platform to craft highly convincing phishing scams designed to pilfer login credentials. This alarming trend involves hosting fraudulent login pages that appear legitimate, making it harder for users to discern the threat.
Security researchers at cofense have recently uncovered this tactic, warning that the fake login screens used in these attacks are meticulously designed to mimic genuine login interfaces, significantly increasing the risk of prosperous credential theft.
the mechanics of the Attack
“The attack begins with an email disguised as an invoice, complete with a link that directs the recipient to a webpage hosted on Google Apps Script,” Cofense researchers explained. This platform is integrated across google’s range of products. By hosting the phishing page within Google’s infrastructure, attackers exploit the inherent trust associated with Google domains.
This creates a deceptive habitat where unsuspecting users are more likely to hand over their sensitive information, believing they are interacting with a secure Google service. The attackers are banking on this trust to bypass typical security warnings and user skepticism.
Legitimate Service, Illegitimate use
Google Apps Script, a JavaScript-based cloud scripting platform, is designed to enable users to automate tasks and extend the functionality of Google Workspace applications such as Sheets, Docs, Drive, Gmail, and Calendar.
These scripts operate on the trusted Google domain “script.google.com,” which is often whitelisted by security products. Attackers exploit this trust by creating scripts that display fake login pages, capturing the credentials entered by victims. The stolen data is then discreetly transmitted to the attacker’s server through a hidden request.

The ease with which anyone with a Google account can publish a script as a public web app, complete with a Google domain, allows threat actors to distribute these malicious links via phishing emails, often bypassing security alerts.
These emails typically feature a call to action related to invoice payments or tax matters, enticing recipients to click the link and unknowingly navigate to the Google-hosted phishing page.

once a victim enters their username and password, they are redirected to the legitimate service they intended to access. This redirection is a tactic used to reduce suspicion while providing the attackers with the necessary time to exploit the stolen credentials.

Defense Measures
The rising abuse of Google Apps Script in phishing campaigns highlights the necessity for robust security measures. One effective strategy involves configuring email security systems to thoroughly examine links to cloud services.
Ideally, organizations should block access to Google Apps Script URLs entirely or, at the very least, flag them as potentially dangerous, providing an extra layer of protection for their users.
Pro Tip: Enable multi-factor authentication (MFA) on all your accounts.Even if your credentials are stolen, MFA adds an extra layer of security by requiring a second verification method.
