Fraudsters are increasingly targeting Indian consumers through a deceptive tactic known as SMS spoofing . In this scam, criminals manipulate sender information in text messages to appear legitimate, often pretending to be from banks or financial institutions. This tactic allows them to access your UPI-linked mobile number and link it to their own devices, potentially exploiting payment or investing apps that depend on UPI.Understanding what is SMS spoofing and implementing protective measures has become essential for safeguarding your financial security in today's digital landscape.

Text message spoofing involves changing the sender's name or phone number to make it look like the message is from someone else. This deceptive practice is primarily enabled through several apps and used by scammers to exploit unsuspecting victims.

Step 1: Impersonation Setup

Spoof texting mainly starts with impersonating well-known brands or public figures to carry out mobile scams. Fraudsters create fake sender IDs that replicate legitimate organisations like banks, government agencies, or trusted companies such as Aditya Birla Capital.

Step 2: Malicious Content Delivery

Next, they send malicious files through WhatsApp, text messages, or messages via any social media platform. These communications often contain urgent language designed to prompt immediate action without proper verification.

Step 3: Device Compromise

Upon clicking that corrupted link, malware gets installed on the victim's device, thus enabling SMS forwarding to a virtual number controlled by the fraudster. This gives scammers access to all incoming messages, including OTPs and transaction alerts.

Step 4: Account Takeover

The fraudster may initiate fraudulent UPI registration and gain control over a victim's account. Also, note that to perform any unauthorised transactions, scammers may employ different social engineering tactics and obtain your MPIN.

Spoofed text message communications come in various forms but have the same intent: to steal your personal information and money. Here is a breakdown of different types:

• 1.Fake Sender Identification This is the most prevalent SMS spoofing form, where hackers create a fake ID to substitute the genuine one, making it appear as a person's bank or credit card provider. The spoofed text message looks identical to legitimate communications, making detection difficult.
• 2. Harassment Cyberbullies, pranksters, and stalkers use this method of text message spoofing to send intimidating or unwanted messages to victims. Their aim may include extracting money from the recipient, too, often through threats or emotional manipulation.
• 3. False Prize Notifications A common scenario involves scammers sending a text message claiming the recipient has won a prize. They then request bank details under the false pretext of depositing the winnings, exploiting people's excitement and trust.
• 4. Espionage

In this case, hackers send a link to a malicious website through an SMS. Upon clicking, this link redirects you to another website, installing malware to gather personal data. They use this information to steal funds or access company resources, making it particularly dangerous for business professionals.

You have likely encountered your fair share of spoofed text message attempts, and knowing how to stop SMS spoofing is crucial for protecting your personal information and finances. Here are essential measures to follow:

• 1. Avoid Downloading Third-Party APK Files Since APK files may contain certain malware or malicious code, your device security may be at risk. Your sensitive information can be prone to theft; hence, avoid downloading any third-party APK files. Always download applications exclusively from Google Play Store or Apple App Store, and verify the publisher name matches official company information before installation.
• 2. Avoid Clicking Suspicious SMS Links If you receive a text with a suspicious link, refrain from clicking on it. Instead, contact the actual company using their official contact details. It is important to note that authorised financial institutions like Aditya Birla Capital will not use SMS to request sensitive information or ask you to click random links.
• 3. Check Sender Details Carefully Pay attention to subtle spelling errors in the sender ID or number. Scammers often make intentional changes to trick inattentive recipients. For example, if you have an account with 'Aditya Birla Capital' and receive a message from 'Aditya Birla Capitall' with an extra letter, it could be a sign of SMS spoofing . Always scrutinise sender details for accuracy and consistency to avoid falling victim to deceptive practices.
• 4. Do Not Reply to Urgent Texts Scammers may create a sense of urgency, demanding immediate action from their target. Be suspicious of unsolicited texts instructing you to take urgent steps. For instance, be cautious if someone suddenly asks you to transfer a significant amount of money, claiming an urgent situation. Legitimate financial institutions provide reasonable timeframes and never pressure you into hasty decisions.
• 5. Check for Encryption Before Clicking a Link Unencrypted URLs in text message spoofing attempts can indicate a scam. Be wary of hyperlinks starting with HTTP instead of HTTPS. Use online URL scanning tools like Google's VirusTotal by copying and pasting suspicious links to ensure safety before clicking.
• 6. Never Disclose Sensitive Information You should never disclose sensitive information like OTPs, card details, card PINs, or MPINs to any representative claiming to be from your bank or financial institution. Legitimate organisations like Aditya Birla Capital never request such information through SMS, calls, or emails. This is a fundamental principle for how to stop SMS spoofing from succeeding.
• 7. Report Suspicious Numbers If someone calls or messages claiming to be from a reputable company and asks for personal information or money, report and block the number immediately. It is important to stay cautious and verify the authenticity of such communications to protect yourself from potential SMS spoofing scams.

If you have fallen victim to a scam involving SMS spoofing , here is what you can do:

• 1.Contact Your Financial Institution Call your bank's customer care number immediately and speak with a customer care representative who will assist you and raise a ticket for your issue. Request temporary freezes on accounts if necessary and enable enhanced monitoring for suspicious activity.
• 2. Submit a Web Form Visit your financial institution's official website and fill out the web form detailing the fraudulent activity. This will help speed up the resolution process and ensure that your concerns are addressed promptly.
• 3. Grievance Reporting Log in to your service provider's official website to report grievances on existing complaints using the previously raised ticket ID. This ensures proper documentation and follow-up.
• 4. Report on Social Media Another crucial way for prevention is by reporting fraudulent incidents through official social media channels of affected organisations. Many financial institutions maintain active fraud reporting systems on these platforms.
• 5.Contact Cyber Cell You can report fraud complaints to the nearest Cyber Crime cell, register a complaint online at the official cybercrime website (cybercrime.gov.in), or call the Cyber Crime cell helpline at 1930. Quick reporting helps authorities track patterns and potentially prevent others from falling victim.
• 6.Change Passwords and Secure Accounts

Immediately change passwords for all financial accounts, email addresses, and any other services where you use similar credentials. Use strong, unique passwords for each account to prevent cascading compromises. Also Read: How to Identify and Avoid Financial Scams?

Understanding frequent errors helps you maintain better security against text message spoofing :

• 1.Trusting Message Appearance Blindly The most dangerous assumption is that messages appearing in legitimate SMS threads or displaying trusted sender IDs must be authentic. Remember: sender information can be manipulated through SMS spoofing . Visual appearance alone never guarantees legitimacy.
• 2.Responding Without Verification Immediately responding to messages—whether clicking links, calling provided numbers, or sharing information—without independent verification enables most spoofed text message success. Always pause, verify through independent channels, and question unexpected requests.
• 3.Sharing Information Too Freely Never share sensitive information through unsolicited communications, regardless of what the sender claims to already know. Legitimate institutions conduct identity verification through secure, authenticated channels within official applications.
• 4.Ignoring Inconsistencies

Many text message spoofing communications contain subtle warning signs: unusual phrasing, grammatical errors, or inconsistent formatting. Pay attention to these red flags and verify before taking action.

SMS spoofing poses various risks, from financial loss to identity theft and malware distribution. Attackers adapt their methods as technology advances, underscoring the need for proactive measures.Understanding what is SMS spoofing , implementing authentication protocols, raising self-awareness, and using secure communication practices are crucial steps to substantially decrease the risk of falling prey to this deceptive practice.Remember, legitimate financial institutions like Aditya Birla Capital never solicit confidential information through unsolicited messages and operate solely through verified official domains. Stay vigilant and alert authorities promptly if you suspect fraudulent activity.
