A new report from Keep Aware highlights the growing threat of employees' personal use of their browser to enterprise cybersecurity. With 70% of phishing campaigns impersonating Microsoft, OneDrive, or Office 365, and malware reassembly in the browser becoming a major concern, security teams must take action to protect their organizations. Learn more about the challenges of browser security and how to address them in this detailed report.
70% of phishing campaigns impersonate Microsoft, OneDrive, or Office 365, exploiting user trust. 150+ trusted platforms like Google Docs and Dropbox are being abused for phishing and data exfiltration. Malware reassembly in the browser has become a significant concern due to threats delivered as fragments that activate inside the browser. Multi-step phishing campaigns have become increasingly sophisticated, serving different content depending on who's viewing. Employees' personal use of AI-powered tools poses new risks for enterprises due to lack of visibility and control over data being pasted into models like ChatGPT. The rise of Shadow IT creates significant security gaps as employees adopt SaaS applications and third-party AI tools without IT oversight. 34% of file uploads on company devices go to personal accounts, often undetected.
Cybersecurity has long been a top priority for enterprises, with organizations investing heavily in security measures to protect their networks and data. However, despite these efforts, a new threat has emerged that is proving particularly challenging for security teams: the use of browsers by employees for personal purposes.
According to recent research from Keep Aware, a leading cybersecurity firm, 70% of phishing campaigns impersonate Microsoft, OneDrive, or Office 365, exploiting user trust. This is just one example of the many ways in which employees' personal use of their browser is threatening enterprise cybersecurity. The researchers found that 150+ trusted platforms like Google Docs and Dropbox are being abused to host phishing and exfiltrate data.
The problem is not limited to phishing attacks alone. Malware reassembly in the browser has become a significant concern, with threats delivered as fragments that only activate when assembled inside the browser – making them invisible to network or endpoint tools. Multi-step phishing campaigns have also become increasingly sophisticated, with phishing pages dynamically serving different content depending on who's viewing.
Furthermore, employees' personal use of AI-powered tools is posing new risks for enterprises. With 75% of employees using generative AI, most enterprises are unaware of what data is being pasted into models like ChatGPT – or what third-party browser extensions are doing in the background. This lack of visibility and control over AI adoption is leaving security teams reactively responding to AI adoption, rather than proactively managing it.
The rise of Shadow IT has also become a major challenge for enterprise security. Employees regularly adopt SaaS applications, personal file-sharing services, and third-party AI tools without IT oversight, often integrating them into daily work with real business data. This lack of visibility and control over these applications is creating significant security gaps that are being exploited by attackers.
In fact, the Keep Aware report found that 34% of file uploads on company devices go to personal accounts, often undetected. This highlights the need for enterprises to have a more nuanced approach to security, one that takes into account the increasingly complex and dynamic nature of modern work.
To address these challenges, security teams must integrate browser security into their enterprise security stack. This means gaining real-time visibility, detecting browser-native threats, and protecting people where they work. It also requires embracing dynamic risk assessments, context-aware access controls, and continuous monitoring.
In addition to these technical solutions, enterprises must also implement stronger review processes, visibility controls, and proactive defenses to secure the browser from the inside out. This includes implementing more robust policies for SaaS applications, AI-powered tools, and personal devices, as well as conducting regular security audits and training employees on cybersecurity best practices.
Overall, the rise of employee's personal use of their browser is a significant threat to enterprise cybersecurity. By understanding these challenges and taking proactive steps to address them, organizations can reduce their vulnerability to these threats and protect their data and networks.
