Frequently asked questions.
What is the biggest data breach in South African history?
By claimed record count, the TransUnion South Africa incident of March 2022 is the largest. The attackers, calling themselves N4aughtysecTU, claimed access to about 54 million records, a figure TransUnion did not confirm.
The largest officially reported figure belongs to the Experian South Africa incident of August 2020: up to 24 million individuals and 793,749 business entities, obtained through social engineering rather than a technical breach.
How do I check if my data was in a South African breach?
First, check haveibeenpwned.com with your email address. It covers most major international and some SA breaches. For South Africa-specific incidents, watch for notices from the affected organisation: Dis-Chem and Cell C both issued public notices, and TransUnion said it would notify affected consumers.
If you believe your data was exposed in any breach, change the passwords on any accounts using that email, enable multi-factor authentication, and watch for unusual banking or SIM-swap activity. South Africans can also apply for free Protective Registration with the Southern African Fraud Prevention Service (SAFPS).
What should a South African business do if it suffers a data breach?
Under South African data protection law, any organisation that suffers a security compromise affecting personal information must notify the Information Regulator and affected individuals as soon as reasonably possible.
First actions in order: isolate affected systems without destroying forensic evidence, change credentials for any compromised accounts, review audit logs to establish scope and timeline, assess whether data was exfiltrated, draft the regulatory notification, and engage legal counsel. Do not wipe systems and do not pay ransom without expert consultation.

Are SA SMBs really being targeted or is it just the big breaches that make the news?
SMBs are targeted constantly, they just do not make headlines. The breaches on this tracker reached mainstream news because of scale or because the organisation was publicly listed or state-owned. Most SA SMB breaches never get published, because the business either quietly pays the ransom, quietly restores from backup, or lacks the detection capability to realise it was breached in the first place.
Attackers often sit inside a compromised network for weeks or months before anyone notices, and most SA SMBs do not have the logging and alerting to shorten that.
How often is this breach tracker updated?
As new confirmed breaches become publicly reported. We list only breaches that have been confirmed by the affected organisation or reported through verifiable media sources. Rumoured or unconfirmed incidents are not included until a confirmable source is available.
I have information about a breach, how do I submit it?
Email hello@immersiveit.co.za with at least one verifiable source (news report, Information Regulator notification, or an on-the-record statement from the affected organisation). We do not publish anonymous tips without a corroborating source.
