Spoof SMS poses an increasing threat to the public, according to the Philippine Chamber of Telecommunications Operators (PCTO), which urges mobile phone users to be especially vigilant in their efforts to combat this sophisticated scam.
Spoofing is a method by which fraudsters impersonate SMS channels to trick recipients. Particularly prevalent in Metro Manila/NCR, the practice has increased significantly since the stringent implementation of SIM registration to prevent SMS fraud last year.
For example, customers have documented occurrences in which fraudulent links to redeem non-existent rewards, such as mobile devices, entice them with messages imitating the sender IDs of telecommunications and banking institutions. Individuals who unwittingly interact with fake SMS senders and divulge confidential and personal information may grant the scammers access to their online accounts, including but not limited to social media profiles, electronic wallets, and banking accounts.

In order to combat spoofing, telecommunications companies, banks, and financial institutions have issued public warnings and collaborated with law enforcement and other partners to track down the scammers.
The PCTO endorses these measures and is working hard with all of its members to make telecom services across the country safer and more reliable.
Atty. Froilan Castelo, PCTO President and Globe General Counsel, said:
Spoofing is a form of cybercrime that is increasingly difficult to detect. We're urging everyone to be extra cautious with any SMS that asks for personal information or prompts to click on a link. Verify the authenticity of such messages by contacting the official customer service channels.
Although not exclusive to the Philippines, spoofing is an issue that affects the entire world. The utilization of illegal equipment referred to as International Mobile Subscriber Identity (IMSI) catchers or counterfeit cell towers facilitates this activity.
Transportable via foot or vehicle, these devices emulate cell towers in order to intercept mobile communications within a specified radius. This allows them to establish connections with and transmit messages to phones within the covered area using sender IDs that mimic official accounts. This approach circumvents the spam filters implemented by telecommunications networks, thereby rendering detection and prevention notably difficult.
The PCTO strongly advises members of the public to notify their service providers of any suspicious messages and to adhere to digital security best practices. This entails exercising caution when accessing personal information via SMS, refraining from clicking on hyperlinks originating from unfamiliar sources, and consistently enhancing their understanding of current fraudulent tactics.
Through the promotion of collective vigilance and the dissemination of information, the PCTO endeavors to protect the general public from these deceitful and detrimental practices.
