How our cybersecurity incident response work is organised
A ransomware attack, a compromised email account or a leaked customer database becomes a legal problem within hours. Our cybersecurity incident response practice helps organisations in Bangladesh, and foreign groups with Bangladeshi operations, make the decisions that cannot wait: what to preserve, who must be told, what can safely be said and which laws apply. We work alongside your IT team, forensic investigators and insurers so that containment and legal judgement move together. This work forms part of our technology, IP and data practice in Bangladesh. Contractual and reputational questions are addressed from the first call.
The legal framework has changed quickly. The Cyber Security Act 2023 was replaced by a 2025 ordinance that reshaped the offences regime and established a National Cyber Security Agency, and the Personal Data Protection Act 2026 adds duties for organisations that handle personal data. Sector rules sit on top. Banks follow Bangladesh Bank guidance on ICT security, telecom operators answer to the BTRC, and listed companies must consider market disclosure. Good cybersecurity incident response starts by identifying which regimes are engaged, because the answer shapes the timing, content and audience of every notice. Each regime has its own audience.
Not every alert is a breach, and not every breach requires the same response. A denial-of-service attack on a public website raises different questions from unauthorised access to payroll records or the theft of payment card data. We help clients classify the incident on the facts available, record why decisions were taken and revisit them as the investigation develops. That matters later, when a regulator, counterparty or court asks what the organisation knew and when. Cybersecurity incident response done well leaves a clear, accurate record rather than rushed statements that later need correcting. It also helps insurers assess cover.
Barrister Tahmidur Rahman advises on the commercial side of incidents, including supplier liability, cloud and outsourcing contracts and cross-border data flows. Adv Syed Wahid, our managing partner, leads litigation and criminal complaints, including police filings and proceedings before the cyber tribunal. Where an incident affects a group with operations abroad, we coordinate with counsel in the UK, US, UAE, China, India and Singapore so that notifications and public statements are consistent in each market. This joined-up cybersecurity incident response reduces the risk that a statement made in one country undermines the position taken in another.
We also help organisations prepare before anything goes wrong. A tested cybersecurity incident response plan, clear escalation lines, template notices, a pre-agreed engagement with a forensic firm and a clear understanding of insurance cover can save days in a real event. We review existing plans against Bangladeshi law and the organisation's contracts, run tabletop exercises with management and train staff on preserving evidence and privilege. If you are dealing with an incident now, contact our Dhaka office by telephone so that the legal assessment can begin straight away. Early cybersecurity incident response advice usually costs far less than repair.

First 72 hours triage
We set up a privileged response structure, engage forensic investigators through counsel where appropriate, and help management separate containment work from legal decisions. We map affected systems, data categories, customers and jurisdictions, identify the regulators that may need to hear from you, and prepare an internal chronology that records what was known at each stage, who decided what, and why each decision was taken. That record proves invaluable later.
Regulatory notifications and engagement
We assess notification duties under the Personal Data Protection Act 2026, cyber security legislation, Bangladesh Bank and BTRC requirements, and any foreign law that applies to the group. We draft notices to regulators, data subjects and counterparties, handle follow-up questions, and keep every statement consistent with the forensic evidence so that early disclosures do not create later liability, contradictions or avoidable regulatory scrutiny. Drafts are reviewed with management.
Ransomware and extortion decisions
Ransom demands raise hard questions on foreign exchange controls, sanctions exposure, anti-money laundering rules, insurance conditions and directors' duties. As part of cybersecurity incident response, we advise boards on the legal risks of each option, help document the decision, liaise with law enforcement where appropriate, and work with negotiators and insurers without compromising the organisation's legal position or later claims. Each option is weighed carefully.
Evidence, complaints and prosecution
We advise on preserving logs, devices and communications so that evidence is usable in Bangladeshi proceedings, including chain-of-custody records and expert reports. Where an insider or outside attacker can be identified, we prepare complaints to the police and the relevant cyber tribunal, seek preservation of records, and support investigators who need information from banks, platforms, telecom operators and other service providers. Our cybersecurity incident response team keeps evidence usable.
Contracts, suppliers and insurance
Many incidents start with a supplier, cloud provider or managed service partner. We review contracts for security obligations, notification clauses, liability caps and indemnities, issue notices to preserve rights, and pursue recovery where justified. We also prepare cyber insurance notifications and coverage arguments, and defend claims from customers, distributors or business partners who seek compensation from the organisation after a breach. Recovery prospects are assessed realistically.
Readiness and governance
We review cybersecurity incident response plans, board reporting lines, vendor contracts and data maps against Bangladeshi law and sector guidance. We run tabletop exercises for management, prepare template notices and holding statements, and help banks, telecom operators and critical information infrastructure owners show regulators that their governance, escalation and recovery arrangements are realistic, documented and regularly tested. Plans are then refreshed after every real incident.
Partner-led, on every matter.

Meet the firm →01What should we do in the first hours of a cybersecurity incident response?
Contain the threat without destroying evidence. Isolate affected systems rather than wiping them, preserve logs, and stop staff discussing the incident on channels that may be compromised. Appoint a small response team with a clear lead, and involve counsel early so that forensic work and internal analysis can be structured to protect privilege where possible. Check insurance policies, because many require prompt notice and the use of approved vendors. Avoid public statements until the basic facts are known. The first hours of cybersecurity incident response often decide how well the organisation can explain itself later.
02Do we have to notify a regulator, customers or the people whose personal data was affected?
It depends on the data, the sector and the facts. The Personal Data Protection Act 2026 introduces obligations on organisations that process personal data, and implementing rules and regulator practice are still developing, so each incident needs a careful reading of the current position. Banks should look at Bangladesh Bank requirements on ICT incidents, telecom operators at BTRC licence conditions, and listed companies at price-sensitive information rules. Foreign law may apply too, for example where European or Indian customers are affected. We map these duties quickly and prepare notices that are accurate without saying more than the evidence supports.
03Is it lawful to pay a ransom from Bangladesh during cybersecurity incident response?
There is no simple answer. Paying a ransom usually means sending funds or virtual assets abroad, which raises foreign exchange control issues under Bangladesh Bank rules, and Bangladesh Bank has warned against dealing in virtual currencies. There may also be sanctions risk if the attackers are linked to a listed group, anti-money laundering reporting duties for regulated businesses, and insurance conditions to satisfy. Directors must also consider whether payment would actually restore systems or prevent publication. We advise boards on these risks, help them record their reasoning and coordinate with law enforcement and insurers before any decision is made.
04How does cybersecurity incident response differ for banks and payment companies?
Financial institutions face closer supervision and tighter expectations. Bangladesh Bank's ICT security guidance expects banks to maintain incident management procedures, report significant events and protect customer funds and data. Payment service providers and mobile financial services operators may also have licence conditions on outages and fraud. Customer losses can lead to complaints and claims, and fraudulent transfers may require urgent requests to freeze funds at receiving banks here and abroad. Cybersecurity incident response in this sector therefore runs on two tracks at once: regulatory reporting and rapid recovery of money before it disappears. Freeze requests should go out within hours.
05Can we keep our forensic report confidential from regulators and claimants?
Possibly, but privilege must be planned rather than assumed. Bangladeshi law protects confidential communications between a client and its lawyer, and reports prepared for legal advice or anticipated litigation have a stronger claim to protection. If the forensic firm is engaged directly by the IT team for business purposes, the report may be harder to protect. Practical steps include engaging investigators through counsel, limiting distribution, separating remediation updates from legal analysis and labelling documents accurately. Where a regulator or court abroad may demand the report, we also take that jurisdiction's rules into account. Labels alone do not create privilege.
06Who is responsible if the breach started with our IT supplier or cloud provider?
Responsibility usually depends on the contract. Many service agreements contain security standards, notification deadlines, audit rights, liability caps and exclusions for indirect loss. We review these terms quickly, send notices that preserve your rights, request the incident information the supplier is bound to provide and consider whether a claim, set-off or termination is justified. Under data protection law, the organisation that decides how personal data is used generally remains answerable to individuals and regulators even if a processor caused the breach, so supplier recovery runs alongside your own compliance steps. We also check insurance terms.
07Should we report the attack to the police, and what happens if we do?
Often yes, but timing and content need care. Reporting can support insurance claims, help trace funds and identify attackers, and may be expected by regulators. Bangladesh has specialist cyber crime units within the police, and offences under cyber security legislation can be heard by the cyber tribunal. A complaint will, however, place facts on a public record and may lead investigators to request devices or documents. We prepare complaints that are accurate and focused, coordinate with the forensic team so that evidence is handed over properly, and manage the interaction between the criminal process and civil recovery.
08How can a cybersecurity incident response plan reduce legal risk for directors?
A plan converts difficult decisions into agreed procedures before pressure arrives. It should name decision-makers, set escalation thresholds, list regulators and counterparties that may need notice, identify forensic and communications partners, and explain how evidence and privilege will be protected. Directors who have approved and tested a realistic plan are better placed to show they acted with care. We review cybersecurity incident response plans against Bangladeshi law, sector guidance and key contracts, and test them through tabletop exercises using scenarios relevant to the business, such as ransomware at a factory or fraud on a payment system.
From first call to resolution.
- 01
Initial call and triage
We take the key facts by telephone, confirm conflicts, set up a privileged structure and identify immediate preservation steps, the regulators that may be engaged and any insurance notice that should be given straight away.
- 02
Investigation and assessment
Working with forensic investigators, we establish which systems and data were affected, classify the incident under Bangladeshi and foreign law, and advise management on notification duties, ransom questions and contractual rights against suppliers where those rights exist.
- 03
Notifications and communications
We prepare and file notices to regulators, data subjects, banks, customers and suppliers, align public statements with the evidence and manage follow-up questions so that the organisation's account stays consistent as facts develop at each stage.
- 04
Recovery and lessons learned
We pursue recovery from suppliers, insurers or attackers, defend claims and regulatory enquiries, and update the cybersecurity incident response plan, contracts and governance so that the same weaknesses are not repeated in future or elsewhere in the group.
