Google notes in its support documentation that only a maximum of 30 recipients can be added to the task.\\n\\nThe fact that these emails can be configured to be sent to any arbitrary email addresses demonstrates the threat actor’s ability to misuse a legitimate automation capability to their advantage and send emails from Google-owned domains, effectively bypassing DMARC and SPF checks.\\n\\n\\”To further increase trust, the emails closely followed Google notification style and structure, including familiar formatting and language,\\” Check Point said. \\”The lures commonly referenced voicemail messages or claims that the recipient had been granted access to a shared file or document, such as access to a ‘Q4’ file, prompting recipients to click embedded links and take immediate action.\\”\\n\\nThe attack chain is a multi-stage redirection flow that commences when an email recipient clicks on a link hosted on storage.cloud.google[.]com, another trusted Google Cloud service. The effort is seen as another effort to lower user suspicion and give it a veneer of legitimacy.\\n\\nThe link then redirects the user to content served from googleusercontent[.]com, presenting them with a fake CAPTCHA or image-based verification that acts as a barrier by blocking automated scanners and security tools from scrutinizing the attack infrastructure, while allowing real users to pass through.\\n\\nOnce the validation phase is complete, the user is taken to a fake Microsoft login page that’s hosted on a non-Microsoft domain, ultimately stealing any credentials entered by the victims.\\n\\n\\n\\nIn response to the findings, Google has blocked the phishing efforts that abuse the email notification feature within Google Cloud Application Integration, adding that it’s taking more steps to prevent further misuse. \\n\\nCheck Point’s analysis has revealed that the campaign has primarily targeted manufacturing, technology, financial, professional services, and retail sectors, although other industry verticals, including media, education, healthcare, energy, government, travel, and transportation, have been singled out.\\n\\n\\”These sectors commonly rely on automated notifications, shared documents, and permission-based workflows, making Google-branded alerts especially convincing,\\” it added. \\”This campaign highlights how attackers can misuse legitimate cloud automation and workflow features to distribute phishing at scale without traditional spoofing.\\”\\n\\nFound this article interesting?
