The incident escalated after reports revealed that as much as 1.2 terabytes of data had been extracted and later leaked online, raising concerns about the scale and depth of the compromise.<br><br>The breach did not originate from core banking infrastructure but from internal administrative and document management systems\u2014an area often less fortified but still rich in sensitive data. Despite this, the exposed dataset reportedly includes customer names, phone numbers, email addresses, ID numbers, and partial card information, confirming that the attack reached deeply into customer-linked records.<br><br>Standard Bank has stated that the breach affected a limited number of customers, although it has not disclosed exact figures. Importantly, the bank maintains that CVV codes were not compromised, and there is no evidence that attackers gained access to customer accounts or funds. However, the presence of card numbers and personal identifiers significantly increases the risk of targeted fraud and social engineering attacks.<br><br>Cybersecurity experts warn that even without full authentication details, datasets of this scale can be weaponised over time. With real customer information in hand, attackers can execute highly convincing phishing campaigns or impersonation scams, particularly in regions where digital banking adoption is rapidly growing but user awareness remains uneven.<br><br>The breach highlights a broader issue facing financial institutions: as systems expand, internal tools and data layers are becoming critical points of vulnerability. In this case, while the bank\u2019s core systems remained intact, the exposure of a large volume of customer data underscores how modern cyber risks are shifting\u2014from direct financial theft to long-term exploitation of personal data.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Standard Bank has confirmed a significant data breach that exposed sensitive customer information, including card numbers and expiry dates, following unauthorised access to its internal systems in March 2026.
