Understanding the Concept of SMS Pumping
Not to be confused with the similar attack of SMS toll fraud, SMS pumping involves the unauthorized sending of a large volume of text messages for fraudulent purposes. In this type of toll fraud, scammers collaborate with mobile network operators to generate revenue from text messages sent to premium-rate numbers. By exploiting vulnerabilities in the system, bad actors can manipulate and exploit unsuspecting businesses.
This type of fraud can have a significant impact, affecting business operations and potentially leading to financial losses. By understanding the concept of SMS pumping, businesses can take proactive measures to detect and prevent this type of fraudulent activity.
How SMS Pumping Works
Let's dive into the inner workings of an SMS pumping fraud operation. While this deceitful practice takes on various forms, the following provides a general overview of how such schemes typically unfold.
- Identifying System Weaknesses: Cybercriminals target vulnerabilities in the telecommunications infrastructure, such as lax security configurations or gaps in account registration processes.
- Crafting Bogus Profiles: Perpetrators employ tactics like automated bots or scripts to fabricate fake profiles that may initially appear legitimate.
- Tapping into Premium Numbers: Fraudsters secure access to premium-rate numbers or premium-service numbers facilitated by telecom carriers. These numbers incur higher charges for calls or texts, with a percentage of fees directed to the carrier.
- Initiating Unauthorized Communication: Once the fraudulent profiles are established, the attackers unleash a torrent of calls or text messages towards these premium numbers.
- Gaining Illicit Profits: The fraudulent activity leads to financial gain for the wrongdoers, who earn a share of the charges incurred. Collaboration between attackers, premium number providers, and telecom insiders often fuels this illicit income.
- Impact on Victims: Businesses find themselves burdened with escalated phone bills due to unauthorized communications directed at premium numbers. Unaware of the scam, they might unwittingly settle the inflated charges.
- Beyond Finances: For businesses, the toll fraud repercussions go beyond finances. The surprise expenses and potential disruptions can taint a company's reputation and disrupt day-to-day operations.
The Impact of SMS Pumping on Businesses
Businesses can suffer significant financial losses as a result of SMS pumping, primarily due to the increased cost of SMS traffic. Fraudulent SMS messages flood systems, overwhelming them and disrupting operations. This type of fraud can affect their bottom line and cause operational challenges. By implementing stronger security measures and staying vigilant, businesses can mitigate the impact of SMS pumping and protect themselves from potentially harmful, illicit web traffic.
A Case Study of a Business Affected by SMS Pumping
$3 million per month in fraudulent SMS charges – that's how much one business started saving in infrastructure costs by removing high volumes of malicious bot traffic engaged in SMS pumping fraud.
By putting the bot detection and prevention platform Arkose Bot Manager in front of the SMS flow, the company saved millions of dollars on downstream benefits, curtailed support hours spent on compromised accounts, slashed fraud-related workload for payment teams, minimized disruption rates for new customers, and effectively cut down infrastructure expenses by eradicating the influx of detrimental bot traffic. Case studies of incidents like these highlight the need for businesses to be proactive in detecting and mitigating SMS pumping fraud.
Detecting SMS Pumping Fraud: Key Indicators
Identifying SMS pumping requires being aware of abnormal patterns with no correlating factor such as a new marketing campaign. One key indicator is an unusually high number of SMS messages sent from a single mobile number. Spikes in SMS traffic during non-peak hours or from specific regions can also raise suspicion.
Monitoring the rate at which SMS messages are being sent and received is crucial for detecting fraudulent activities. By keeping an eye out for these red flags and analyzing the patterns, businesses can better protect themselves from bad actors seeking to exploit their systems.

SMS pumping can disrupt business operations by overwhelming communication channels and clogging up systems. This fraudulent activity may require businesses to allocate resources for investigating and resolving the issues caused by SMS pumping.
What Makes Your Business a Target for SMS Pumping?
Businesses can become targets for SMS pumping if they heavily rely on SMS communication or verification processes. Certain industries, like financial institutions, e-commerce sites, and online platforms, may be more vulnerable due to the nature of their operations. Additionally, weak security measures or improperly protecting one-time password authentication methods can make a business an attractive target.

Strategies to Prevent and Mitigate SMS Pumping
Implementing bot detection and prevention systems adds an extra layer of security against unauthorized account setups. Rate limits and monitoring systems aid in detecting and preventing SMS pumping fraud. Partnering with reliable mobile network operators (MNOs) equipped with robust security measures minimizes the risk of SMS pumping.
