We have (an expensive) problem: Navigating The High Cost of Cybersecurity Breaches in South Africa

Cybersecurity breaches are a global issue, but for South Africa, the stakes are particularly high. Recent findings by Allianz’s cybersecurity report for 2024 place South Africa 14th among the countries hardest-hit by cyberattacks, with an average data breach costing the country an eye-watering R49 million. While companies are investing more heavily in cybersecurity, these figures reveal just how costly a breach can be—both financially and in terms of reputational damage.

The Rising Threat of Data Breaches

A data breach occurs when confidential and sensitive information is unlawfully exposed, often for malicious reasons such as extortion or identity theft. These breaches are frequently the result of ransomware attacks, where hackers encrypt the victim’s data and demand a ransom in exchange for a decryption key. However, data breaches and ransomware attacks are not one and the same; in a data breach, attackers aim to steal sensitive information, whereas ransomware attacks focus on locking the victim’s data.

The rise in ransomware attacks, including data exfiltration, is linked to evolving tactics used by cybercriminals and the growing interconnection between organisations that share vast amounts of personal records. In South Africa, this has become all too apparent, with several high-profile breaches making headlines over the past few years.

High-Profile Cyberattacks in South Africa

South Africa’s public and private sectors have both fallen victim to multiple devastating cyberattacks, which have led to millions of rands in damages and ransoms. One recent attack targeted e-commerce platform OneDayOnly, where the hacking group KillSec demanded a $100,000 (approximately R1.78 million) ransom to prevent the release of stolen data. The attack compromised supplier information, further highlighting the dangers companies face when storing sensitive information.

In March 2022, credit bureau TransUnion suffered a significant ransomware attack. Hackers claimed to have accessed data from three million South African customers and leaked the ID numbers of six million more. TransUnion refused to pay the ransom, leading to concerns over the compromised data. Just two years earlier, another credit bureau, Experian, had been attacked, exposing the personal information of 24 million South Africans and 793,749 businesses.

The government has not been immune to these attacks, either. In early 2024, ransomware group LockBit targeted the Government Pensions Administration Agency (GPAA), demanding a ransom with a threat to release stolen data. The GPAA refused to pay, and as a result, LockBit released a 668GB archive of sensitive information. Similarly, the National Health Laboratory Service (NHLS) was attacked by BlackSuit, a hacking group that claimed to have stolen 1.2 terabytes of patient and client data.

The Hidden Costs of Data Breaches

The direct financial costs of these breaches, such as ransom demands, are just the tip of the iceberg. Even when organisations refuse to pay, the long-term consequences of data breaches can be devastating. Sensitive data—ranging from credit card numbers to personal health information—can fall into the wrong hands, leading to further attacks.

Attackers often use the stolen data for phishing or vishing scams, where they manipulate victims into giving up even more sensitive information. For example, a recent phishing attack targeted South African Revenue Service (SARS) eFiling users, tricking them into believing they owed outstanding payments. The more personal information attackers have, the easier it is to make these scams appear legitimate and convince people to fall for them.

Why Are Cyberattacks So Expensive?

The multi-million average cost per data breach in South Africa is driven by multiple factors, including the ransom itself, the cost of recovering systems, and the damage to an organisation’s reputation. A single breach can cripple a company’s operations for days or even weeks, leading to lost revenue and customer trust. In industries such as healthcare, where patient information is at risk, the fallout can be even more severe, with potential lawsuits and regulatory fines adding to the financial burden.

According to Allianz’s report, many of these attacks could have been avoided or mitigated with stronger cybersecurity measures. Despite increased investments, weak security practices still plague many South African organisations, leaving them vulnerable to sophisticated cyberattacks.

What Can Organisations Do?

As cyberattacks become more frequent and costly, it’s crucial for South African organisations to stay proactive in their defence. Some steps companies can take include:

•  Strengthening cybersecurity frameworks: Investing in robust security infrastructure, including firewalls, encryption, and advanced threat detection systems, can help safeguard sensitive data.

•  Employee training: Human error is often a weak point in cybersecurity. Regular training on identifying phishing attempts and other cyber threats can significantly reduce the risk of breaches.

•  Incident response planning: Developing a clear and actionable incident response plan ensures that organisations can react quickly to a breach, minimising damage and recovery time. 

Ultimately, beyond the monetary losses, organisations face the potential for long-term damage to their reputation, customer trust, and operational stability. This is why it is imperative that companies continue to invest in and prioritise cybersecurity to stay one step ahead. After all, the cost of prevention is always lower than the cost of a breach.
