Overseas Filipino Workers lose an estimated ₱2.3 billion annually to cybercrime, with incidents ranging from identity theft and online banking fraud to sophisticated romance scams and ransomware attacks that destroy years of savings in minutes. The unique vulnerabilities OFWs face – managing finances across multiple countries, using public WiFi in shared accommodations, maintaining long-distance relationships through digital channels, and often lacking technical support in foreign countries – create perfect conditions for cybercriminal exploitation. Recent incidents include 3,000 OFWs in Saudi Arabia falling victim to a coordinated phishing campaign targeting remittance accounts, healthcare workers in the UK losing access to critical documents through ransomware, and construction workers in Dubai having their identities stolen for illegal loan applications in the Philippines. This technical manual provides comprehensive cybersecurity strategies specifically designed for OFW threat landscapes, covering everything from basic digital hygiene to advanced protection techniques that safeguard both digital assets and physical safety.

Understanding the OFW Threat Landscape

Attack Vectors Specific to Overseas Workers

The remittance ecosystem creates the most lucrative attack vector for cybercriminals targeting OFWs. Fake remittance websites mimicking legitimate services like Western Union or RemitHome steal login credentials and payment information. SMS phishing claiming remittances failed or require verification trick workers into revealing authentication codes. Man-in-the-middle attacks on remittance apps operating over unsecured WiFi capture transaction details. These attacks succeed because they exploit the urgency and emotion around supporting families, with criminals timing campaigns around Philippine typhoons or medical emergencies when workers are most vulnerable.

Employment-related scams leverage job insecurity inherent in contract work. Phishing emails claiming visa expiration, contract termination, or new job opportunities contain malware that steals personal information. Fake recruitment agencies create elaborate websites and social media presence to collect placement fees and identity documents. Ransomware specifically targets OFWs’ digital documents – passports, contracts, certificates – knowing these are irreplaceable abroad. The average ransomware demand has increased to $5,000, calibrated to what criminals believe OFWs can desperately gather.

Social engineering attacks exploit emotional vulnerability of isolated workers. Romance scammers spend months building relationships before requesting money for fabricated emergencies. Fake family emergency calls using voice synthesis technology impersonate relatives requesting immediate wire transfers. Social media manipulation involves criminals befriending OFWs to gather personal information used for identity theft or targeted attacks. These psychological attacks prove more effective than technical exploits because they bypass security measures through human trust.
