How can you prevent SMS spoofing attacks?

One of the most effective ways to combat SMS spoofing is by building awareness in the user community. Ensure that all users are aware of the ease by which the identity of an SMS sender can be falsified and that they realize that the source of a message cannot be taken at face value. Encourage that users validate the identity of an SMS sender through alternate sources such as MFA and that they avoid sending sensitive info such a credit card or account numbers over SMS.

Fraud in Telecom industry is, unfortunately, rampant. It has become a major pain point for the industry, leading to an astonishing USD39.9 billion in global telecom revenue loss in 2021, equating to 2.22% of the total revenue. SMS spoofing is one of the key tools scammers use. SMS spoofing is this sneaky trick where scammers disguise their identity in text messages, making it look like the SMS is coming from someone you trust – think your bank or a buddy.

Preventing SMS spoofing attacks involves implementing several security measures. Firstly, utilizing sender authentication protocols like Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) helps verify the legitimacy of the sender's identity. Secondly, implementing Sender ID validation and Domain-based Message Authentication, Reporting, and Conformance (DMARC) policies can detect and prevent unauthorized use of sender identities. Additionally, encrypting SMS messages and utilizing secure communication channels, such as Transport Layer Security (TLS), helps protect against interception and tampering. Furthermore, educating users about the risks of SMS spoofing can mitigate the impact of such attacks.

We need to use some more robust and secure protocols in order to avoid SMS spoofing. Also, we need to spread awareness of identifying sender ID.

SMS spoofing often involves confusion, deception, and scams, exploiting trust in sender IDs. A main problem is due to the fact that verifying SMS origins isn't as straightforward as with email. Blockchain technology, noted for security and transparency, is explored as a solution, offering a decentralized method to authenticate message origins through a tamper-proof registry of verified senders. - This approach can reduce spoofing by ensuring messages are verified against blockchain records. - But challenges with integration into current systems, scalability, and broad adoption remain. - Despite obstacles, blockchain's potential to secure digital communications continues to be a promising exploration area.

A low cost method of spoofing/social engineering is when the perpetrator pretends to be someone else sending a message from a "borrowed" or alternate phone. The sender will identify themselves as a person of confidence, typically a manager or executive in the recipient's company and claim they are about to enter an important meeting and rapidly need sensitive information to be sent to an unverified number.

A particularly treacherous way of spoofing is to send the user a link in the SMS to a spoofed site pretending to belong to a particular bank or financial institution, where the user is prompted to enter personal information, including passwords that could be quickly compromised.

With the latest developments in AI, it's no brainer that Telcos are using disruptive power of AI and Generative AI to detect fraudulent activities like SMS spoofing. It's got this knack for spotting patterns and anomalies that scream "fraud."

Most good banks will tell you immediately that they will never ask for passwords, account information, or personal data over SMS or even if they call you. If your financial institution is calling or SMSing, they already know your information. If a person gets an SMS saying they are from any business, or even person, best practice is to never respond to that SMS or to any numbers in the message. Go online to that institution’s official site, contact them that way, and ask them if they sent you a text.

Educate your user community regarding the risks of SMS spoofing and limit the use of this format for introductory, high level or informal messages that limit the risk if they are compromised.

While its a serious challenge to spot SMS spoofing, AI can most certainly play a key role. By constantly learning from heaps of data, AI can quickly flag messages that don't fit the bill, alerting you before you even think about clicking. It's like having a super-smart friend who whispers, "Hey, something's fishy about this message," keeping you one step ahead of the tricksters.

We need to add extra layer of security in order to have secure information transfer from sender to reciever. Additional layer of security can be added through various cryptographic algorithms so that the data is safe.

Spoofing attacks, a lurking fear, Verify senders, make it clear. Authentication, 2FA's might, Educate users, keep them bright. Anti-spoofing filters, block the fake, Encrypt messages, no room to break. Monitor traffic, stay in control, Update security, protect your goal.

One way to prevent spoofing is to use App based authentication instead of an OTP based. Herein user is sent a link on SMS using which an OTP is generated on the mobile application instead of the same being sent in the SMS text. Current fintech players such as PayTM and One card in India use this method. It helps to prevent frauds linked to OTP and SMS spoofing. On similar lines, enterprises can also implement a second factor of authentication along with SMS to be double sure that the user is genuine. From a network end, CSPs can deploy anti-spoof systems using blockchain based applications that can detect and block spoofing. Traditionally CPaaS platforms have been struggling with such issues but are using AI now to detect the spam message
