BGD e-GOVT CIRT mentions some of the recent notable cyber-attacks targeting Bangladesh. These include a hacker group claiming a cyber-attack on payment gateways, law enforcement agencies and the banking sector in Bangladesh on 1 August. . On 3 July, a hacker group claimed a Distributed Denial-of-Service (DDoS) attack on Bangladeshi transportation service making the website unavailable for an hour.

CIRT requested all organisations in Bangladesh to take the following measures to ensure their infrastructures’ security: Ensure strict network and user activity monitoring 24/7, especially during non-office hours, and watch out for any indication of data exfiltration; ensure implementing load balancer solutions to ensure that no single server is overwhelmed during an attack, deploy a Web Application Firewall to analyze incoming HTTP/HTTPS traffic and filter out malicious requests and traffic patterns commonly associated with DDoS attacks; ensure vital services such as DNS, NTP as well as network middleboxes are securely configured and are not exposed on the internet; validate and sanitize all user input to prevent malicious code injection (e.g., SQL injection, Cross-Site Scripting) that could lead to web defacement; perform regular backups of your website’s content and database, enforce HTTPS on your website with SSL/TLS encryption; keep all web server software, content management systems (CMS), plugins, and other software components up-to-date with the latest security patches; configure and harden web application as per OWASP guideline and report or inform BGD e-GOV CIRT regarding the detection of IOCs and/ or any suspicious activities you observe within your environment.
