In this scheme, fraudsters <\/span><a class=\"ql-size-16px\" style=\"color: #0066cc;\" href=\"https:\/\/www.politico.com\/newsletters\/weekly-cybersecurity\/2023\/02\/21\/inspired-by-kyiv-dhs-eyes-new-foreign-partnerships-00083724\" target=\"_blank\" rel=\"noopener noreferrer\"><u>register premium-rate phone numbers<\/u><\/a><span class=\"ql-size-16px\"> through questionable telecom providers. They then use automated tools to send repeated login or verification requests. Each request triggers an SMS message, often for two-factor authentication or account verification. The service provider pays for each SMS sent, and the scammers collect a share of the charges. This method does not have a formal definition from cybersecurity authorities, but experts describe it as a way to abuse SMS-based systems for profit.<\/span><\/p>\n<h3><strong class=\"ql-size-22px\">Alternate Names<\/strong><\/h3>\n<p><span class=\"ql-size-16px\">You might see SMS Pumping called by other names in the telecommunications industry. These terms all describe similar fraudulent activities:<\/span><\/p>\n<ul>\n<li><span class=\"ql-size-16px\">SMS toll fraud<\/span><\/li>\n<li><span class=\"ql-size-16px\">Artificially Inflated Traffic (AIT) fraud<\/span><\/li>\n<\/ul>\n<p><span class=\"ql-size-16px\">These names highlight the main goal of the scam: to create fake SMS traffic and generate illegal revenue. The attackers use the same tactics to trick businesses into sending large volumes of SMS messages to numbers they control.<\/span><\/p>\n<h3><strong class=\"ql-size-22px\">Why It Matters<\/strong><\/h3>\n<p><span class=\"ql-size-16px\">SMS Pumping poses a serious threat to your business and your users in 2025. Attackers use bots to flood SMS systems with fake requests. They exploit automatic SMS sending features, such as one-time passcodes (OTPs) and appointment confirmations. This attack can cause major financial losses. For example, <\/span><a class=\"ql-size-16px\" style=\"color: #0066cc;\" href=\"https:\/\/commsrisk.com\/elon-musk-says-twitter-lost-60mn-a-year-because-390-telcos-used-bot-accounts-to-pump-a2p-sms\/\" target=\"_blank\" rel=\"noopener noreferrer\"><u>Twitter lost about $60 million each year<\/u><\/a><span class=\"ql-size-16px\"> because of SMS Pumping. Sectors like banking, e-commerce, and healthcare face even greater risks. Attackers can overwhelm OTP and confirmation systems, leading to service disruptions and higher costs.<\/span><\/p>\n<p><span class=\"ql-size-16px\">You must stay alert and use strong defenses. Regular monitoring, employee training, and up-to-date security tools are key to stopping SMS Pumping before it causes damage.<\/span><\/p>\n<h2><strong class=\"ql-size-28px\">How SMS Pumping Works<\/strong><\/h2>\n<h3><strong class=\"ql-size-22px\">Attack Methods<\/strong><\/h3>\n<h4><strong class=\"ql-size-16px\">Bots and Scripts<\/strong><\/h4>\n<p><span class=\"ql-size-16px\">Attackers use bots and automated scripts to launch SMS Pumping attacks. You may notice that these bots target phone number input fields on websites and apps. When a bot fills out these forms with fake or sequential phone numbers, it triggers the system to send one-time passcodes (OTPs) or other SMS content. This process creates a flood of SMS messages, overwhelming both the recipient&#8217;s device and your messaging infrastructure.<\/span><\/p>\n<ol>\n<li><span class=\"ql-size-16px\">Bots fill out online forms with fake or sequential phone numbers.<\/span><\/li>\n<li><span class=\"ql-size-16px\">The system sends a large volume of SMS messages to these numbers.<\/span><\/li>\n<li><span class=\"ql-size-16px\">This flood causes delays for real users and increases your SMS costs.<\/span><\/li>\n<li><span class=\"ql-size-16px\">Attackers use this method to disrupt services, drain prepaid accounts, or intercept sensitive information.<\/span><\/li>\n<li><span class=\"ql-size-16px\">Bots bypass normal user interaction, making it hard to spot the attack right away.<\/span><\/li>\n<\/ol>\n<h4><strong class=\"ql-size-16px\">Premium-Rate Numbers<\/strong><\/h4>\n<p><span class=\"ql-size-16px\">Fraudsters often register premium-rate or high-cost phone numbers through certain mobile network operators. When your system sends SMS messages to these numbers, you pay a higher fee. Attackers receive a share of this revenue, turning your SMS system into a source of profit for them. They automate the process, sending thousands of messages to these numbers in a short time. This method not only increases your costs but also makes detection more difficult because the traffic looks like normal SMS activity.<\/span><\/p>\n<h3><strong class=\"ql-size-22px\">Exploited Services<\/strong><\/h3>\n<h4><strong class=\"ql-size-16px\">OTPs and App Links<\/strong><\/h4>\n<p><span class=\"ql-size-16px\">You rely on SMS-based OTPs and app links for user authentication and onboarding. Attackers know this and target these endpoints. Bots flood your website or app with fake phone numbers, causing your system to send OTPs and app links to numbers controlled by fraudsters. These numbers often have similar or sequential patterns, such as ending in 1000, 1001, 1002, and so on. This pattern helps attackers automate the attack and maximize profits.<\/span><\/p>\n<ul>\n<li><span class=\"ql-size-16px\">Fraudsters use bots to send many fake OTP requests.<\/span><\/li>\n<li><span class=\"ql-size-16px\">These requests trigger OTPs or app links to be sent to their controlled numbers.<\/span><\/li>\n<li><span class=\"ql-size-16px\">The attack inflates your SMS traffic and costs.<\/span><\/li>\n<li><span class=\"ql-size-16px\">Monitoring for rapid OTP requests from similar phone numbers can help you detect this activity.<\/span><\/li>\n<\/ul>\n<h4><strong class=\"ql-size-16px\">Automated Responses<\/strong><\/h4>\n<p><span class=\"ql-size-16px\">Many businesses use automated SMS responses for appointment confirmations, password resets, or notifications. Attackers exploit these features by sending repeated requests, often through bots. Each request triggers an SMS, which adds to your operational costs and can disrupt service for real users. Automated responses are easy targets because they often lack strong verification checks.<\/span><\/p>\n<h3><strong class=\"ql-size-22px\">Collusion and Coordination<\/strong><\/h3>\n<p><span class=\"ql-size-16px\">Attackers do not work alone. They often coordinate with premium-rate number providers, especially certain mobile network operators. This collaboration allows them to send large volumes of SMS messages to premium numbers, inflating your costs. The attackers, MNOs, and sometimes third-party aggregators share the profits from these inflated charges. This setup resembles affiliate marketing, where fraudsters earn commissions for driving high SMS traffic.<\/span><\/p>\n<p><span class=\"ql-size-16px\">Mobile network operators play a key role in SMS Pumping. Some MNOs have weak security or gaps in their registration processes, making it easier for attackers to exploit their systems. Reliable MNOs help prevent SMS Pumping by offering fraud detection tools and supporting rate limits. You should choose partners with strong security measures to reduce your risk.<\/span><\/p>\n<h2><strong class=\"ql-size-28px\">Impact of SMS Pumping<\/strong><\/h2>\n<h3><strong class=\"ql-size-22px\">Financial Loss<\/strong><\/h3>\n<p><span class=\"ql-size-16px\">You face a real financial threat from SMS Pumping. In 2023, businesses around the world <\/span><a class=\"ql-size-16px\" style=\"color: #0066cc;\" href=\"https:\/\/www.mobileeurope.co.uk\/5-of-application-to-person-smss-were-fraudulent-in-2023\/\" target=\"_blank\" rel=\"noopener noreferrer\"><u>spent about $1.16 billion on fraudulent SMS messages<\/u><\/a><span class=\"ql-size-16px\">. This number only covers direct costs, such as inflated SMS charges. When you add expenses for service interruptions, investigations, customer support, and reputation repair, the total loss grows even larger. Experts expect the global financial impact to reach several billion dollars in 2025. The Communications Fraud Control Association reported that <\/span><a class=\"ql-size-16px\" style=\"color: #0066cc;\" href=\"https:\/\/cfca.org\/telecommunications-fraud-increased-12-in-2023-equating-to-an-estimated-38-95-billion-lost-to-fraud\/\" target=\"_blank\" rel=\"noopener noreferrer\"><u>telecom fraud caused $39 billion in losses in 2023<\/u><\/a><span class=\"ql-size-16px\">, with SMS fraud making up a large part of that amount. If you run a business that relies on SMS for authentication or communication, you risk losing money every time attackers trigger fake messages. These losses can threaten your profits and even your ability to operate.<\/span><\/p>\n<h3><strong class=\"ql-size-22px\">Operational Issues<\/strong><\/h3>\n<p><span class=\"ql-size-16px\">SMS Pumping does not just drain your budget. It can also disrupt your daily operations. Attackers often use bots to flood your systems with fake SMS requests. For example, <\/span><a class=\"ql-size-16px\" style=\"color: #0066cc;\" href=\"https:\/\/cybersecuritynews.com\/threat-actors-turning-messaging-service-into-a-cash\/\" target=\"_blank\" rel=\"noopener noreferrer\"><u>one attack used over 500 fake identities<\/u><\/a><span class=\"ql-size-16px\"> to target a company&#8217;s onboarding process, causing major service slowdowns. Twitter lost about $60 million each year because bots abused its two-factor authentication system. You might see your SMS services overloaded, which can force you to suspend them temporarily. This action blocks real customers from getting important messages.<\/span><\/p>\n<ul>\n<li><span class=\"ql-size-16px\">You may overspend on SMS without gaining real customers.<\/span><\/li>\n<li><span class=\"ql-size-16px\">Your team might need to spend extra time and money on new security tools.<\/span><\/li>\n<li><span class=\"ql-size-16px\">Customer service staff could get overwhelmed with complaints about failed messages.<\/span><\/li>\n<li><span class=\"ql-size-16px\">OTP fraud can lead to more login attempts with stolen credentials, raising your risk of data breaches.<\/span><\/li>\n<\/ul>\n<p><span class=\"ql-size-16px\">A sudden spike in SMS traffic, especially from unusual locations or with similar phone numbers, often signals an attack. If you do not act quickly, you risk losing both money and customer trust.<\/span><\/p>\n<h3><strong class=\"ql-size-22px\">User Disruption<\/strong><\/h3>\n<p><span class=\"ql-size-16px\">Your users also suffer when SMS Pumping strikes. Attackers can send SMS messages to premium-rate numbers, causing your customers to face unexpected charges. Some users may even see their credit scores drop or their reputations damaged. Fraudsters sometimes trick users into signing up for costly services or clicking on dangerous links. These scams can expose users to phishing or malware attacks.<\/span><\/p>\n<ul>\n<li><span class=\"ql-size-16px\">Users may not receive important authentication codes on time.<\/span><\/li>\n<li><span class=\"ql-size-16px\">Service quality drops, leading to frustration and lost trust.<\/span><\/li>\n<li><span class=\"ql-size-16px\">Security risks increase as attackers try to steal personal information.<\/span><\/li>\n<\/ul>\n<p><span class=\"ql-size-16px\">When your business faces SMS Pumping, your users may lose faith in your service. This loss of trust can hurt your brand and make it harder to keep loyal customers.<\/span><\/p>\n<h2><strong class=\"ql-size-28px\">How to Detect SMS Pumping<\/strong><\/h2>\n<h3><strong class=\"ql-size-22px\">Traffic Patterns<\/strong><\/h3>\n<p><span class=\"ql-size-16px\">You can spot suspicious activity by watching for unusual traffic patterns in your SMS systems. Attackers often use bots or automated scripts to send rapid and repeated requests for OTPs or verification codes. These requests usually target a small set of phone numbers that fraudsters control. You may also notice:<\/span><\/p>\n<ul>\n<li><span class=\"ql-size-16px\">Sudden spikes in SMS request frequency<\/span><\/li>\n<li><span class=\"ql-size-16px\">High volumes of messages sent to a few numbers<\/span><\/li>\n<li><span class=\"ql-size-16px\">Use of proxies or VPNs to hide the true origin of requests<\/span><\/li>\n<li><span class=\"ql-size-16px\">Mismatches between claimed user locations and actual IP or phone number locations<\/span><\/li>\n<li><span class=\"ql-size-16px\">Bulk identical content sent in a short time<\/span><\/li>\n<\/ul>\n<p><span class=\"ql-size-16px\">Behavioral analytics and <\/span><a class=\"ql-size-16px\" style=\"color: #0066cc;\" href=\"https:\/\/blog.geetest.com\/en\/article\/how-device-fingerprinting-enhances-security\" target=\"_blank\" rel=\"noopener noreferrer\"><u>device fingerprinting<\/u><\/a><span class=\"ql-size-16px\"> also help you find multiple fraudulent requests from the same source. AI-driven traffic analysis can flag messaging volumes that do not match normal user behavior. When you see a sudden increase in messages from a small region or specific service, you should investigate right away.<\/span><\/p>\n<h3><strong class=\"ql-size-22px\">Anomaly Monitoring<\/strong><\/h3>\n<p><span class=\"ql-size-16px\">You need strong anomaly monitoring to protect your SMS channels. Start by setting rate limits to restrict how many SMS messages a user or device can request in a short time. This step reduces the risk of automated abuse. Use machine learning algorithms to spot and block unusual authentication patterns as they happen. Here are some effective techniques:<\/span><\/p>\n<ol>\n<li><span class=\"ql-size-16px\">Rate limiting per user or per minute<\/span><\/li>\n<li><span class=\"ql-size-16px\">Real-time anomaly detection using machine learning<\/span><\/li>\n<li><span class=\"ql-size-16px\">Continuous monitoring and auditing of SMS traffic<\/span><\/li>\n<li><span class=\"ql-size-16px\">Geo-fencing to control SMS activity by location<\/span><\/li>\n<li><span class=\"ql-size-16px\">Device behavior analysis, such as checking for risky devices or repeated misuse<\/span><\/li>\n<\/ol>\n<p><span class=\"ql-size-16px\">You can also use advanced methods like ARIMA or EWMA to find unusual spikes in SMS traffic. Training your employees to recognize signs of fraud adds another layer of defense.<\/span><\/p>\n<h3><strong class=\"ql-size-22px\">Dashboard Tools<\/strong><\/h3>\n<p><span class=\"ql-size-16px\">Modern dashboard tools give you real-time visibility into your SMS traffic.
