Telecom cyberattack: 5 things you should know

In the wake of a significant cyberattack targeting Telecom Namibia, critical questions have emerged about the company’s data security practices and the implications for its customers.

Here are the five key takeaways from the incident and what it means for all stakeholders.

1. What Happened?
   On December 11, Telecom Namibia fell victim to a ransomware attack orchestrated by a group known as Hunters International. This ransomware-as-a-service operation exfiltrated an estimated 626.3GB of data, comprising 492 633 files.

The attackers set a ransom deadline, threatening to release the stolen data if their demands weren’t met. When the deadline passed, hundreds of sensitive customer records, including identification documents, addresses, and banking details, were leaked and began circulating on social media.

Namibia’s Data Protection Act, which could impose significant fines and penalties for such data breaches, has not yet been enforced, leaving customers with limited recourse under statutory law. However, common law principles may allow for claims of damages due to negligence in safeguarding data.

2. The Impact on Customers
   For Telecom customers, this breach is more than a corporate cybersecurity failure — it’s a personal privacy crisis. Leaked data could expose individuals to identity theft, financial fraud, and phishing scams. Sensitive information like bank account details, personal IDs, and contractual records are now potentially accessible to malicious actors on the dark web.

The breach also raises broader questions about organisational responsibility and the long-term risks to customers. The public circulation of this data on social media increases the likelihood of targeted phishing attacks, where cybercriminals use leaked information to craft convincing scams aimed at stealing even more personal or financial details. These attacks could lead to severe financial and psychological consequences for affected individuals, including long-term damage to their financial security and creditworthiness.

Namibia’s lack of enforcement of its Data Protection Act means customers cannot yet rely on statutory protections, placing a greater burden on individuals to monitor their accounts, secure their personal information, and remain vigilant against future scams.

3. What Does This Mean for Telecom Namibia?
   The reputational damage to Telecom Namibia cannot be overstated. The public release of sensitive customer data exposes the company to potential lawsuits, particularly under common law claims of negligence. Additionally, the incident could result in financial losses due to lost business, regulatory scrutiny, and the cost of mitigating the breach.

Telecom Namibia also faces increased scrutiny of its data protection practices. This incident highlights the urgent need for stronger internal controls, as well as compliance with international cybersecurity standards. The company must act decisively to rebuild customer trust and ensure that similar breaches do not occur in the future.

4. Lessons for Organisations
   This cyberattack serves as a stark reminder of the steps businesses must take to protect their systems and customers’ data from increasingly sophisticated threats.

Here are some key takeaways from this scenario:
● Organisations must continuously assess and update their cybersecurity measures to keep pace with evolving threats.

● Companies should assume that leaked information will be weaponised in phishing attacks. This reinforces the need to proactively educate customers on how to recognise and avoid such scams.

To address the fallout from this breach and prevent similar incidents in the future, Telecom Namibia and other organisations must act decisively.

Immediate steps should include:
● Conducting a thorough investigation of the breach to identify the root cause and address vulnerabilities, with the assistance of third-party cybersecurity experts.

● Strengthen security systems, including firewalls, intrusion detection systems, and endpoint protection, to deter future attacks.

● Engage and educate customers on the risks of phishing attacks, particularly in the wake of this breach, by offering clear guidance on identifying fraudulent emails and securing their accounts.

The Telecom Namibia cyberattack is a sobering reminder of the stakes in today’s digital landscape. For businesses, cybersecurity is no longer optional — it is a foundational requirement.

This incident also highlights the pressing need for Namibia to enforce its Data Protection Act, as the lack of statutory penalties may embolden poor data security practices across organisations.

While the damage has been done, the path forward involves learning from this failure and building resilience to prevent similar incidents in the future. Telecom Namibia has an opportunity to turn this crisis into a wake-up call, leading by example in prioritising cybersecurity and customer trust.
