In 2023, the Federal Bureau of Investigation issued a public service announcement about deceptive text messages that appear to come from trusted organizations or contacts. These messages often urge recipients to click a link, reply with personal details, or open an attachment to resolve a supposed issue. The FBI warned that such texts can trick people into revealing passwords, downloading malware, or sending money. This evergreen explainer outlines how these text-based social engineering campaigns work, what the FBI specifically advised the public to watch for, and evidence-based steps you can take to reduce risk.
The Nature of the FBI Warning About Text Messages
The FBI’s warning focuses on a form of phishing conducted via short message service (SMS) and other text-based platforms. These messages may impersonate government agencies, financial institutions, delivery services, or familiar contacts. Common scenarios include claims of a blocked account, an unexpected package, an overdue bill, or a compromised account that requires immediate action. By pressing a link or replying, victims may be directed to fake login pages, asked to pay with gift cards, or prompted to install apps that secretly harvest data. The warning underscores that legitimate organizations typically use multiple verified channels rather than relying solely on unsolicited text messages.
How These Text Messages Work
Fraudsters rely on urgency, fear, or excitement to prompt quick, unthinking responses. A text may display a spoofed sender ID that mimics a known number or organization logo. The linked destination can be a convincing counterfeit site that harvests credentials, or it may silently install malicious code. Messages can also direct users to call a number where a scammer continues the manipulation by phone. Once attackers gain access to accounts or devices, they may steal money, personal information, or use the compromised device to target others. These techniques often persist because small interactions can reveal patterns that help criminals refine their campaigns.
Previous Incidents and Trends Linking to SMS Phishing
Prior to the 2023 warning, the FBI’s Internet Crime Complaint Center (IC3) had logged significant increases in reported losses from business email compromise and SMS phishing, often called smishing. These reports highlighted how text messages bypass some security controls that block emails, especially on mobile devices that lack robust filtering. Attackers have also blended SMS with other methods, such as follow-up voice calls or messages that appear to come from delivery or banking apps. Understanding this evolution helps contextualize why the FBI emphasized public awareness and specific protective behaviors.

Practical Protective Measures
Protecting against deceptive text messages involves a combination of technical safeguards, habits, and verification steps. Start at the device level by enabling automatic updates for your operating system and apps, which ensures you receive security patches for known vulnerabilities. Turn on built-in protections, such as message filtering and known-block lists offered by many mobile carriers and operating systems. Treat unexpected or unusual texts as suspicious even if they appear to come from a trusted contact, and use a separate channel to confirm the request. Avoid clicking links or calling numbers provided in the message unless you independently verified them through an official website or known phone number.
Immediate Steps After Receiving a Suspicious Text
- Do not tap links, download attachments, or reply with personal information.
- Check the message against known account notifications through an official website or app.
- Contact the organization directly using verified contact details from their official site or documentation.
- Report the message to your mobile carrier, and consider forwarding it to the FBI’s IC3 for tracking and analysis.
- Inspect the device for unusual behavior, and run a reputable security scan if you suspect a malicious app or link interaction.
Broader Context and Related Risks
Text-message-based deception is one part of a larger ecosystem of social engineering that includes email phishing, voice phishing (vishing), and business email compromise. Attackers often integrate multiple channels, starting with a text that leads to a phone call or a follow-up email. Businesses and individuals with publicly visible contact details may be at higher risk, especially if information about roles, vendors, or projects is openly shared. Recognizing the patterns across these tactics helps build a more resilient approach to communication security.
Recognizing Common Indicators
Certain characteristics frequently appear in fraudulent text campaigns. These include requests for secrecy, pressure to act immediately, offers that seem too good to be true, and messages that create a sense of fear or urgency around your accounts or packages. Legitimate organizations usually identify themselves clearly and provide ways to verify the communication through established, documented channels. Being skeptical of unexpected texts that deviate from normal communication patterns reduces the likelihood of falling for these schemes.
Reporting and Community Awareness
Reporting suspicious text messages helps authorities track campaigns and trends, which can inform public warnings and defenses. In the United States, you can report fraud and cybercrime to the FBI’s Internet Crime Complaint Center. Mobile carriers also rely on user reports to improve filtering and blocking at the network level. Community awareness, including discussions with colleagues, friends, and family, spreads practical advice and makes it harder for criminals to exploit trust and familiarity.
Collaborative Defense Practices
- Share verified guidance from organizations such as the FBI and CISA within your workplace or community group.
- Encourage use of multi-factor authentication on accounts that support it, reducing the impact of stolen credentials.
- Promote secure configuration of devices, such as automatic updates and safe browsing settings.
- Establish internal protocols for verifying urgent requests that arrive via text or other informal channels.
FAQ
Reader questions
How can I verify whether a text message is legitimate?
To verify, contact the organization directly using a phone number or website you trust from an independent source, such as a statement, billing document, or official app. Do not rely on contact details within the message itself. Examine the message for spelling errors, unusual urgency, or requests that deviate from standard procedures.
What should I do if I already clicked a link or shared information?
If you clicked a link, disconnect from sensitive accounts, run a security scan, and change passwords from a known-clean device. If you shared financial information, contact your bank or payment provider immediately. Report the incident to your mobile carrier and the FBI’s IC3 to support broader tracking and response efforts.
Can my mobile carrier protect me from these messages?
Many carriers offer tools such as message filtering, suspected-spam warnings, and blocking options. While these tools are helpful, they are most effective when combined with personal vigilance and good verification habits. Check your carrier’s settings and enable available protections.
