Cell towers are essential assets to wireless coverage with their capability to enable seamless connectivity and communication. However, like most technologies that are advancing, the digital threats posed to them are advancing as well. Recently, fake cell towers, a sophisticated fraud tactic, have become increasingly more prominent. Fake cell towers mimic legitimate cell towers to intercept communications, capture personal data, and conduct SMS scams. Luckily, there are ways to protect yourself and your data.
What Are Fake Cell Towers?
Fake cell towers pose as legitimate cell sites. They are made up of unauthorized devices that trick nearby phones into connecting to them instead of connecting to a genuine network. These devices can capture phone numbers, text messages, call information, and location data, and may go by other names such as IMSI (International Mobile Subscriber Identity) catchers or Stingrays. Fake cell towers can also inject fake text messages, luring unsuspecting users into scams.
Whereas a phone will typically connect to the nearest, strongest cell tower within range, fake cell towers trick mobile devices into automatically connecting to them instead. Once connected, this is where the damage happens. Fake towers can intercept data, including texts, calls, and app usage data. Cybersecurity experts have also raised concerns about fake cell towers being mobile and hard to detect, as sometimes they can be housed in small, portable devices.
The Rise of SMS Scams Through Fake Cell Towers
Fake cell towers do not stop at intercepting data, they also play a role in SMS scams that have become quite cumbersome in recent years. Scammers send fake text messages through these towers, claiming to be banks, telecom providers, or other online services. Unsuspecting victims may be deceived by malicious links or duped into giving personal information that can lead to data theft and financial fraud.
Multiple organizations have been working to make people aware of this increasing threat. Smart Communications has recently issued an alert regarding the rise in SMS scams that present users with fake websites and links requiring sensitive information. Google has also been working to raise awareness about the risks of these fake cell towers and how quickly these scams can be executed. Google has been urging caution in high-traffic areas, as scammers have been known to utilize mobile stations to blast scam SMS messages directly to phones they connect with, often connecting to unsuspecting users.
How to Protect Yourself Against Scammers
This new method of digital fraud may feel overwhelming, especially as this type of scamming happens fast and often goes unrecognized until it’s too late, but many preventative measures can be taken to protect yourself and your data.
- Be cautious with SMS messages. Do not click on links or download files from unsolicited text messages, especially those asking for personal information. Legitimate companies typically will not ask for sensitive information over text.
- Verify links and sources. If you receive a suspicious message claiming to be a service provider, bank, mail courier, or other service, directly contact the institution instead of following the provided link.
- Enable two-factor authentication (2FA) to add an additional layer of security. If scammers do capture your credentials, they still cannot access your accounts without successfully completing the two-factor authentication.
- Limit sensitive activities on public networks and avoid entering sensitive information such as passwords or banking information. Take caution when connecting to networks at malls, airports, events, or other large, populated areas as fake cell towers will mainly be deployed in crowded, high-traffic areas to reach the highest possible number of vulnerable users.
- Consider using encrypted communication apps. Encrypted apps offering end-to-end encryption protect messages from being intercepted, adding an additional layer of security.
- Keep your phone’s software up to date. Operating system updates often include security patches that address vulnerabilities in your device. Staying updated helps protect from ill-natured interception.
- Use VPN (Virtual Private Network) services to encrypt your internet connection. This makes it difficult for fake cell towers to capture your data.
You’re Not Alone: What Telecom Providers and Governments Are Doing
Telecom providers and governments are aware of the threats that fake cell towers pose and are working to mitigate them. Some companies are actively informing the public on how to recognize SMS scams linked to deceptive devices and offering the ability to report scam messages. Other providers are working on the offensive, investing in advanced monitoring systems that can detect unusual activity, and potentially shutting down the fake towers before posing a risk to users.
Governments are also working alongside telecom providers to increase regulation and oversight of mobile network signals, aiming to detect unauthorized IMSI catchers. Improving regulation can help limit the availability of such devices and penalize unauthorized use.
Conclusion
Fake cell towers can cause a lot of damage and are a nuisance at the least, however, their emergence is a reminder to keep yourself aware and protected. Users can take preventative steps by understanding how these devices operate and properly protecting their own personal information and devices. Although major companies and governments are working together to mitigate such threats, the best defense against possible risks from cell towers remains awareness and caution.
