Description

A recent phishing campaign uncovered by EclecticIQ researchers reveals an advanced approach used by financially motivated attackers to target the telecommunications and financial sectors. The attackers embedded malicious links within Google Docs presentations, leveraging the platform’s trusted domain to bypass typical email filters and endpoint protections. By using Google Docs for initial delivery, the attackers were able to evade detection by anti-phishing tools, making their malicious schemes appear more credible and trusted. Once victims interacted with the links in the Google Docs files, they were redirected to fraudulent login pages hosted on Weebly. These pages closely mimicked the login screens of well-known brands, including AT&T and major U.S. and Canadian financial institutions. The goal was to deceive users into entering their login credentials, multi-factor authentication (MFA) codes, and other sensitive personal information. The use of Weebly, a legitimate platform, further obscured the attackers' intentions, reducing the likelihood that their phishing sites would be flagged as malicious. In addition to the deceptive login pages, the attackers incorporated legitimate tracking tools like Sentry.io and Datadog into their phishing sites. These tools allowed them to monitor user interactions, collecting valuable data such as IP addresses, geolocation, and timestamps. This information was used to refine future phishing attempts, increasing their effectiveness and precision. In some instances, attackers escalated their attacks by performing SIM swapping to intercept SMS-based MFA codes, effectively bypassing an important layer of account security. The report underscores the importance of transitioning to more secure forms of MFA, such as app-based or hardware-based solutions, to mitigate the risks posed by this sophisticated phishing campaign.
