Cybercrime in Bangladesh: Latest Threats and Protection Methods

Cybercrime in Bangladesh is growing faster than cybersecurity awareness. As digital financial services, social media, e-commerce, and online communication have become central to daily life for tens of millions of Bangladeshis, the attack surface available to cybercriminals has expanded dramatically. In 2026, the threats are more sophisticated, more targeted, and more financially damaging than at any previous point, and understanding the specific threats facing Bangladeshi users is the foundation of effective protection.

The Scale of the Problem

Bangladesh's Cyber Security Agency and the digital crime unit of the Bangladesh Police have reported consistent year-over-year increases in cybercrime complaints. Financial fraud, including mobile banking scams, online shopping fraud, and identity theft, accounts for the largest share of reported cases. Social media account hacking, sextortion, and business email compromise are among the fastest-growing categories.

The financial losses to Bangladeshi individuals and businesses from cybercrime run into hundreds of crores of taka annually, and these figures almost certainly understate the true scale, as many victims do not report incidents due to shame, distrust of the reporting process, or lack of awareness that reporting options exist.

Threat 1: Mobile Financial Services Fraud

Mobile banking fraud targeting bKash, Nagad, Rocket, and bank mobile apps is Bangladesh's most prevalent cybercrime category by case volume. The most common attack vectors include social engineering calls where criminals impersonate financial institution representatives and convince victims to share OTPs; SIM swap attacks where criminals convince mobile operators to transfer a victim's number to a criminal-controlled SIM; and fraudulent agent transactions where victims are directed to unregistered agents who steal deposits.

Protection: Never share your OTP or PIN with anyone, including callers identifying themselves as bKash, Nagad, or bank representatives. Legitimate financial services never request PINs or OTPs through inbound calls. Enable biometric authentication on all financial apps. If you receive a suspicious call, hang up and call the official number directly.

Threat 2: AI-Powered Phishing and Deepfakes

AI has dramatically improved the quality of phishing attacks available to cybercriminals. Phishing messages in 2026 are personalized, grammatically perfect, contextually relevant, and visually identical to legitimate communications from banks, government agencies, and e-commerce platforms.

Deepfake audio, realistic voice recordings fabricated using AI, is being used in Bangladesh to impersonate family members in distress calls requesting emergency money transfers. Deepfake videos are being deployed in sextortion schemes using AI-generated intimate content to extort victims.

Protection: Treat any unexpected urgency in digital communications as a red flag, regardless of apparent source. Verify any financial request from a "family member" through a direct phone call to a number you already know. No legitimate institution will ever request credentials, OTPs, or money via messaging or video call.

Threat 3: Social Media Account Hacking

Facebook account hacking, where criminals gain access to accounts to conduct financial scams targeting the victim's contacts, spread misinformation, or extract personal data, is among the most commonly reported cybercrimes in Bangladesh. Hackers use stolen passwords from data breaches, phishing links, and malicious apps requesting excessive permissions.

Protection: Enable two-factor authentication (2FA) on your Facebook account immediately if you have not already done so. Use a unique password for Facebook not shared with any other service. Review and revoke permissions for any third-party apps connected to your account that you do not recognize or actively use.

Threat 4: E-commerce and Online Shopping Fraud

Fraudulent online sellers operating through Facebook marketplace, fake e-commerce websites, and compromised legitimate accounts are collecting payments for goods that are never delivered. Advance fee fraud, where buyers are asked to pay customs or delivery fees for packages that do not exist, is particularly prevalent.

Protection: Buy from sellers with extensive verified reviews and established trading histories. Use payment methods that offer dispute resolution rather than direct bank transfers for marketplace transactions. Be deeply skeptical of prices significantly below market rates they are the most reliable signal of fraudulent listings.

Threat 5: Ransomware Targeting Bangladeshi Businesses

Ransomware attacks, malware that encrypts business data and demands payment for its release, are increasingly targeting Bangladeshi SMEs, whose cybersecurity defenses are typically less mature than those of large corporations but whose operational data is critically valuable.

Protection: Maintain regular, tested backups stored separately from main systems. Keep all software updated promptly. Train staff to recognize phishing emails as the most common ransomware delivery mechanism. The cost of prevention is orders of magnitude lower than the cost of recovery.

Reporting Cybercrime in Bangladesh

Cybercrime victims in Bangladesh can report incidents to the Police Cyber Support for Women (01320000888), the Bangladesh Computer Incident Response Team (BGD e-GOV CIRT), and the Cyber Crime Investigation Division of the Bangladesh Police. Reporting is important, as it enables law enforcement to identify patterns, pursue perpetrators, and warn other potential victims.

The digital economy's benefits are real and substantial. Protecting yourself from its risks is a practical responsibility, and the knowledge to do so is entirely accessible.
