File sharing has become an essential part of business operations, enabling seamless collaboration and more efficient workflows. However, with that convenience comes a significant risk of phishing attacks targeting shared files. According to a recent report from Abnormal Security, file-sharing phishing attacks increased by 350% between June 2023 and June 2024, highlighting the urgent need for secure file sharing practices.
Understanding the Phishing Threat in File Sharing
Phishing attacks related to file sharing often involve cybercriminals disguising malicious files or links as legitimate documents or shared resources. When users download or open these files, they may unknowingly install malware, ransomware, or give hackers access to sensitive data. Phishing is often tricky, as it uses fake messages that appear to be from people or companies you trust to deceive you.
7 Must-Know Practices for Secure File Sharing
To protect your business from these evolving threats, consider implementing the following best practices for secure file sharing:
1. Use Trusted and Secure Platforms
Choose reputable file-sharing services that prioritize security, such as SharePoint, OneDrive, Dropbox Business, or Google Drive. These platforms often include built-in encryption, access controls, and activity monitoring.
2. Enable Multi-Factor Authentication (MFA)
Always enable MFA for your accounts. This adds an extra layer of protection by requiring a second form of verification, making it more difficult for attackers to gain unauthorized access.
3. Verify Sender and Link Authenticity
Before clicking on shared links or downloading files, confirm the sender’s identity, especially if the message is unexpected. Be wary of suspicious email addresses, unusual link formats, or typos. When in doubt, contact the sender directly through a known channel.
4. Implement Strict Access Controls
Limit file access to only those who need it. Utilize role-based access control (RBAC) to prevent granting broad access rights. Regularly review sharing permissions and revoke access when necessary.
5. Educate and Train Employees
Regular cybersecurity training helps staff recognize phishing attempts and respond appropriately. Encourage employees to scrutinize unfamiliar links, avoid opening suspicious attachments, and report any potential threats immediately.
6. Keep Software and Security Tools Up to Date
Ensure your operating system, antivirus software, and security patches are current. Many cyberattacks exploit known vulnerabilities that updates can fix.
7. Use Antivirus and Anti-Malware Solutions
Incorporate reliable security solutions that scan files for threats before they’re opened. Many file-sharing platforms offer integrated security features that detect and block malicious activity.
Microsoft Office 365 and SharePoint: Built for Secure File Sharing
