Phishing in Google Drive: Recognizing Malicious File Sharing Requests
As educators increasingly rely on Google Drive to share lesson plans, collaborate on documents, and store sensitive information, phishing scams are evolving to exploit this environment. Instead of focusing solely on email, attackers now create convincing file-sharing requests to trick users into granting access or sharing login credentials. Understanding these tactics and spotting suspicious requests is essential for keeping your school community safe.
How Phishing in Google Drive Works
Traditional phishing attempts often come in emails directing you to fake login pages or malicious attachments. When it comes to Google Drive, attackers use a similar strategy but with a twist:
Fake Shared Documents: Scammers may send a legitimate-looking email notification that a file or folder has been shared with you. At first glance, it looks like a standard Google Drive alert.
Misleading Links and Fake Previews: The shared link might take you to a deceptive login page or a document embedded with malicious links. Instead of viewing a genuine resource, you’re led to a page designed to steal your credentials or infect your device.
Exploiting Familiar Names: Attackers often impersonate trusted colleagues, administrators, or vendors. Using recognizable names increases the chances you’ll trust and open the link without a second thought.
Signs of a Malicious File-Sharing Request
Being vigilant and knowing what to look for can significantly reduce the risk of falling for a Drive-based phishing scam. Keep an eye out for these red flags:
Unfamiliar Email Addresses: Even if the sender’s name appears familiar, look closely at the email address. Slight differences—such as an extra letter or a misspelling—can indicate fraud.
Unexpected File Shares: If you receive a shared document notification you weren’t expecting, approach it cautiously. Before opening, verify with the sender through a known contact method (e.g., their official school email).
Urgent or Threatening Language: Phrases like “Your account will be locked” or “Immediate action required” should raise suspicion. Attackers rely on fear and urgency to prompt you into reacting without thinking.
Suspicious File Names or Content: If the shared file’s title or description seems irrelevant, vague, or unrelated to your work, that’s a signal it might not be legitimate.
Requests for Passwords or Personal Info: Google Drive and legitimate collaborators will never ask you to enter credentials or personal information in a shared file.
Verifying a Shared Document’s Legitimacy
Before opening or interacting with a shared Google Drive file, take a moment to verify its authenticity:
Check the Sender’s Profile: Hover over the sender’s name in the sharing notification to see the email address. If it doesn’t match the person you think it is or ends with an unfamiliar domain, that’s a red flag.
Contact the Sender Offline: If a colleague supposedly sent the file, send them a quick email or chat message—using a known address or channel—to confirm they shared it.
Use Google Drive’s Built-In Tools: Open Google Drive directly (rather than clicking the link in the email) and search for the file by name. It’s likely not legitimately shared with you if it doesn't show up.
Hover Over Links: If the document contains links, hover over them to see where they lead before clicking. If the URL looks suspicious or doesn’t align with Google’s official domains, steer clear.
Protecting Yourself and Your School Community
A few proactive measures can help prevent falling victim to Drive-based phishing:
Enable Multi-Factor Authentication (MFA): Adding an extra layer of security to your accounts makes it harder for attackers to access them, even if they steal your password.
Educate Staff and Students: Conduct regular training sessions on recognizing phishing attempts. The more people know what to look for, the safer your community will be.
Report Suspicious Activity: If you receive a suspicious file-sharing request, report it to your school’s IT department and mark it as phishing in Gmail. Early reporting can protect others from falling for the same scam.
Keep Your Browser and Antivirus Software Updated: Ensuring your tools are current helps protect against known vulnerabilities scammers might exploit.
Check the Activity Dashboard in Google Drive: Review who accessed shared documents and confirm that the activity aligns with your expectations.
What to Do If You’ve Fallen for a Scam
If you inadvertently clicked a malicious link or provided your information:
Change Your Password Immediately: Update your Google Workspace password and any other accounts using the same credentials.
Notify Your IT Department: Prompt reporting allows the tech team to investigate the incident, take preventative measures, and advise you on the next steps.
Monitor for Unusual Activity: Monitor your Google Drive and other accounts for unauthorized changes, unusual file shares, or unexpected sign-ins.
Final Thoughts
Phishing scams evolve constantly, and with more educators relying on digital tools, attackers see schools as inviting targets. By staying informed, remaining cautious, and following best practices, you can significantly reduce the risk of falling victim to these malicious file-sharing requests. Remember: when in doubt, verify the source before you click, and encourage your colleagues and students to do the same.
