In an alarming development, the government of Bangladesh has issued a stern alert about potential targeted cyberattacks on its cyber infrastructure, specifically slated for August 15. The looming threat comes from a hacker group that has brazenly declared its intention to disrupt the country’s digital ecosystem.
The Warning: Government on High Alert
The Computer Incident Response Team (BGD e-GOV CIRT) under the Information and Communication Technology (ICT) Division of the Bangladesh Computer Council sounded the alarm on August 4. The agency, responsible for tackling and mitigating cybersecurity incidents, urged all critical information infrastructures, banks, financial institutions, healthcare entities, as well as governmental and non-governmental organizations, to be on high alert due to the imminent threat of a cyber onslaught.
Hacker Group’s Threat: Unleashing a Digital Storm
The hacker group, self-styled as ‘Hacktivist,’ issued a chilling declaration on July 31, vowing to launch a “storm of cyber attack” on Bangladesh’s cyber system on August 15. The announcement sent shockwaves across the nation’s digital landscape, prompting immediate action from BGD e-GOV CIRT.
Common Ideology: Shared Targets
BGD e-GOV CIRT’s recent investigation reveals that multiple hacker groups, influenced by a shared ideology, have been consistently orchestrating cyber attacks on various organizations within Bangladesh. The group behind the impending cyber threat identifies as members of an Indian hacker group, and their attack plan extends to both Bangladesh and Pakistan.
Unveiling Attack Tactics
The anticipated attack is projected to encompass a range of tactics that these hacktivist groups have historically employed. Distributed Denial-of-Service (DDoS) attacks, website defacements, website compromise, and malicious PHP shells as backdoors are among their primary strategies. The groups are aiming for small to medium-scale cyber attacks, which can have considerable disruptive consequences.
High-Value Targets: In the Crosshairs
According to BGD e-GOV CIRT’s findings, the most vulnerable sectors to these cyber threats include Government and Military entities, Law Enforcement Agencies, Banking and Non-Bank Financial Institutions (NBFI), Pharmaceuticals, Retail, and Industrial Organizations, as well as the Energy and Education sectors. Given the range of industries at risk, all critical institutions, including information technology (IT) infrastructures, must adopt comprehensive measures to safeguard their digital assets.
Strengthening Cyber Resilience
To counter these looming threats, organizations, especially banks, must establish cybersecurity operation centers in alignment with the directives of the Bangladesh Bank. This proactive approach is critical to thwarting large-scale cyberattacks. The exponential growth of cyberattacks on financial institutions necessitates proactive planning and implementation of security measures to protect against potential disruptions.
Defending Against DDoS
One particularly prominent attack method is the Distributed Denial-of-Service (DDoS) attack, where hackers seek to overwhelm a network or system by flooding it with an excessive volume of traffic. The attack arsenal includes tactics like TCP Push Flood, UDP Flood, TCP RST Flood, TCP SYN Flood, TCP Window Size Flood, and IP Fragment Flood. Implementing a strong anti-DDoS protection threshold, updated hardware and software, and adhering to digital security guidelines are vital to fend off these attacks.
Historical Precedent: Past Incidents
Bangladesh’s digital landscape is no stranger to cyberattacks. In April 2021, over 200 government and private entities, including the Bangladesh Telecommunication Regulatory Commission, Bangladesh Bank, commercial banks, and internet service providers, experienced a severe cyberattack. The breach compromised confidential information and highlighted the gravity of cybersecurity concerns.
Proactive Measures: Securing the Future
Given the persistent threats, the government must take a proactive stance. Conducting cyber resilience audits, strategizing secure sourcing methods, and eliminating vulnerabilities from systems are crucial steps to safeguard the nation’s digital ecosystem. Ensuring the protection of systems, data, and customer information remains paramount.
As August 15 approaches, Bangladesh’s cybersecurity landscape is on high alert. The government’s warning underscores the urgency for organizations to fortify their defenses against potential cyberattacks. By bolstering cyber resilience, adopting comprehensive security measures, and adhering to best practices, Bangladesh can mitigate the threats and secure its digital future.
