Beware: Fake SharePoint Updates Scamming Indian Companies in 2026 (Phishing Attack)

Cybercriminals are using a sneaky trick involving Microsoft SharePoint to steal data and money from Indian organizations. This scam uses a vulnerability to trick people into thinking they're accessing legitimate files.

What Is the Microsoft SharePoint Server Spoofing Vulnerability (CVE-2026-32201)?

The Microsoft SharePoint Server Spoofing Vulnerability (CVE-2026-32201) is a security flaw that cybercriminals are actively exploiting to target Indian businesses. SharePoint is a widely used platform for collaboration and document management, making it a prime target. The vulnerability allows attackers to disguise malicious links or attachments, making them appear as if they originate from a trusted source within the organization or from a known partner.

This isn't just a theoretical threat; it's actively being used in phishing campaigns targeting employees across various industries in India. The sophistication of these attacks often bypasses standard security measures, leading to significant data breaches and financial losses. While there aren't specific advisories from RBI directly tied to this particular vulnerability yet, they consistently warn about phishing attacks leveraging trusted brand names – and this SharePoint scam falls squarely into that category. CERT-In (the Indian Computer Emergency Response Team) also regularly issues warnings about vulnerabilities in widely used software, urging users to keep their systems updated with the latest security patches.

How This Scam Works — Step by Step

Here's how fraudsters are using this vulnerability to trick victims in India:

1. Target Identification: Attackers first identify organizations in India that heavily rely on Microsoft SharePoint for document sharing and internal communication. This information is often gleaned from websites, LinkedIn profiles, or even by monitoring online forums.
2. Crafting the Phishing Email/Message: The cybercriminal crafts a very convincing phishing email or WhatsApp message. It typically impersonates someone within the victim's organization (a senior manager, IT support, or even a colleague) or a well-known business partner. They may spoof the sender's email address to make it appear legitimate.
3. The Lure: The message contains a link or attachment that appears to lead to a critical update, urgent project file, or a shared document on SharePoint. The language used creates a sense of urgency, pressuring the recipient to click without thinking. For example, it might say "Urgent: Security Update Required for SharePoint Access" or "Important: New Project Guidelines – Requires Immediate Review."
4. Malicious Link/Attachment: When the victim clicks the link, they are directed to a fake login page that looks identical to the legitimate SharePoint login screen. Alternatively, opening the attachment installs malware on their device without their knowledge.
5. Credential Theft/Malware Installation: If the victim enters their username and password on the fake login page, the attacker steals these credentials. This gives them access to the victim's actual SharePoint account, and potentially other accounts if the victim reuses passwords. If the victim opens the malicious attachment, it could install ransomware, spyware, or other harmful software onto their device.
6. Data Exfiltration/Financial Fraud: Once the attacker gains access, they can steal sensitive data, including financial records, customer information, and intellectual property. They might also use the compromised account to send phishing emails to other employees or clients, further expanding the attack. In some cases, they might use the stolen information to commit financial fraud, such as initiating fraudulent UPI transactions or accessing bank accounts.

Real Warning Signs to Watch For

• Unexpected Emails/Messages: Be suspicious of emails or WhatsApp messages about SharePoint updates or files, especially if you weren't expecting them.
• Sense of Urgency: Messages that create a strong sense of urgency demanding immediate action are big red flags. Phrases like "Act Now," "Immediate Attention Required," or "Your Account Will Be Suspended" are designed to trick you.
• Suspicious Links/Attachments: Hover over links before clicking to see the actual URL. If it looks unfamiliar or contains misspellings (e.g., "sharepoint.micorsoft.com" instead of "sharepoint.microsoft.com"), don't click it. Never open attachments from unknown or suspicious sources.
• Generic Greetings: Phishing emails often use generic greetings like "Dear User" instead of addressing you by name.
• Unusual Requests: Be wary of requests for your username, password, Aadhaar number, or other sensitive information via email or messaging apps, especially when accompanied by a request to update these details for Sharepoint.
• Grammatical Errors: Poor grammar and spelling mistakes are common in phishing emails.
• Mismatched Sender Information: Check the sender's email address carefully. Even if the name looks familiar, the actual address might be different from what you expect.

What Happens to Victims

The consequences of falling victim to this SharePoint spoofing scam can be devastating for both individuals and organizations.

• Financial Loss: Stolen credentials can lead to direct financial losses through fraudulent transactions, unauthorized access to bank accounts via UPI, or even identity theft. Attackers can use stolen Aadhaar details to obtain loans or SIM cards in the victim's name.
• Data Breach: Sensitive company data falling into the wrong hands can lead to reputational damage, legal liabilities, and loss of customer trust.
• Business Disruption: Ransomware infections resulting from malicious attachments can cripple business operations, leading to significant downtime and financial losses.
• Emotional Distress: Victims often experience stress, anxiety, and feelings of shame or vulnerability. The process of recovering from a cyberattack can be time-consuming and emotionally draining. Especially where identity theft is involved.

What RBI and CERT-In Say

RBI consistently cautions users against sharing sensitive information like bank account details, OTPs, and UPI PINs with anyone. They also emphasize the importance of being vigilant against phishing attacks. CERT-In regularly issues advisories about vulnerabilities in software and hardware. While not directly about this SharePoint scare, these advisories urge users to keep their systems updated to protect against exploitation. The central government’s I4C (Indian Cyber Crime Coordination Centre) runs the cybercrime.gov.in portal.

If you or your business fall victim, contact the 1930 cybercrime helpline.

How to Protect Yourself

Here's how to stay safe from this SharePoint scam:

1. Enable Multi-Factor Authentication (MFA): MFA adds an extra layer of security to your SharePoint account, making it much harder for attackers to gain access even if they have your password.
2. Verify Sender Identity: Always double-check the sender's email address and, if possible, confirm the message's legitimacy through a separate communication channel (e.g., a phone call).
3. Be Cautious with Links and Attachments: Never click on links or open attachments from unknown or suspicious sources. Hover over links to preview the URL before clicking.
4. Keep Your Software Updated: Regularly update your operating system, web browser, and Microsoft SharePoint Server with the latest security patches.
5. Educate Employees: Train your employees about phishing scams and how to identify them. Conduct regular security awareness training sessions to keep them informed about the latest threats.
6. Use Strong Passwords: Use strong, unique passwords for all your online accounts, and consider using a password manager to help you keep track of them.
7. Implement Email Filtering: Use email filtering software to block phishing emails and other malicious content.

What to Do If You've Been Targeted

If you suspect you've been a victim:

1. Change Your Passwords Immediately: Change the passwords for your SharePoint account and any other accounts that may have been compromised.
2. Report the Incident: Immediately report the incident to your IT department or security team. Also, file a complaint with the National Cyber Crime Reporting Portal (cybercrime.gov.in).
3. Contact Your Bank: If you suspect that your financial information has been compromised, contact your bank immediately and report the incident. Block UPI access.
4. Monitor Your Accounts: Keep a close eye on your bank accounts (including UPI accounts) and credit reports for any signs of unauthorized activity.
5. Contact Cybercrime Helpline: Call the 1930 cybercrime helpline immediately to report the incident and seek assistance.
6. Alert Your Contacts: Inform your contacts about the phishing attempt so they can be on the lookout for suspicious messages.
7. Preserve Evidence: Take screenshots of any suspicious emails or messages and preserve them as evidence for the authorities.

Frequently Asked Questions

Q: How can I tell if a SharePoint login page is fake?

A: Look closely at the URL in the address bar. Fake login pages often have URLs that are slightly different from the legitimate SharePoint website (e.g., using a different domain or including misspellings). Also, check for the padlock icon in the address bar, which indicates a secure connection (HTTPS). However, even some fake pages use HTTPS, so you should scrutinize the URL very carefully.

Q: What if I accidentally clicked on a phishing link but didn't enter any information?

A: Even if you didn't enter any information, it's still a good idea to run a full scan of your computer with a reputable antivirus program to check for malware
