ShinyHunters Breach Cloud Storage, Ransom Request Denied

Payment processor Checkout.com has disclosed a significant data breach following a targeted attack by the notorious cybercrime group ShinyHunters. This incident has sent ripple effects across the fintech sector, raising immediate concerns about the vulnerabilities inherent in payment processing systems. Fortunately, the company’s swift and transparent response has provided some reassurance to its merchant partners and customers.

The Breach Details

The breach was made possible when ShinyHunters exploited a legacy cloud storage system that had been abandoned since 2020. Rather than being properly decommissioned and secured, this outdated infrastructure remained accessible, containing sensitive internal records and essential merchant onboarding information. Such oversights remind us of the importance of maintaining rigorous security protocols, especially when it comes to legacy systems.

According to Checkout.com’s investigation, approximately 25% of the company’s current merchant base could potentially be affected by this data exposure. This alarming statistic highlights the wide-reaching implications of the breach and underscores the significance of proactive security measures in safeguarding sensitive information.

Just last week, the cybercriminals contacted Checkout.com with a ransom demand, effectively pressing the company to conduct a thorough security investigation. Such incidents are becoming increasingly common in today’s digital landscape, and they place organizations in difficult positions. However, amidst the chaos, Checkout.com reported that its active payment processing environment remained secure throughout the incident. No payment card numbers, merchant bank funds, or live transaction data were compromised, significantly limiting the potential damage from the breach.

Mariano Albera, Chief Technology Officer at Checkout.com, took full responsibility for the company’s failure to adequately shut down the legacy system. This candid acknowledgment of security oversight not only demonstrates accountability but also emphasizes the company’s commitment to transparency—an essential element for maintaining merchant trust during challenging times.

Albera stated that Checkout.com is actively notifying all potentially affected parties and is cooperating fully with law enforcement and regulatory authorities. This proactive approach is critical, as timely communication can help mitigate the risks and restore confidence among customers and stakeholders.

In a bold move that sets Checkout.com apart from many organizations facing similar extortion threats, the company has taken a principled stance by firmly refusing to pay the ransom demanded by ShinyHunters. Instead of capitulating to cybercriminals, Checkout.com has committed to donating an equivalent amount to cybersecurity research initiatives at prestigious institutions, including Carnegie Mellon University and Oxford University’s Cyber Security Center. This philanthropic gesture not only supports the fight against cybercrime but also positions Checkout.com as an ethical leader in the fintech space.

This incident serves as a crucial lesson for the broader fintech industry: legacy systems represent a significant security vulnerability if not properly decommissioned. Checkout.com’s experience is a cautionary tale that highlights the paramount importance of comprehensive infrastructure management and the dangers of leaving outdated systems operational.

In response to the breach, the company has pledged to strengthen its security posture further, ensuring that affected merchants receive the necessary support and information. Checkout.com has also committed to maintaining open communication channels for any concerns merchants may have. This approach aims to foster trust and alleviate fears among users regarding the integrity of their financial operations.

By refusing to reward cybercriminals and investing in cybersecurity research, Checkout.com is positioning itself as an industry leader committed to systemic security improvements. This philosophy of resilience not only seeks to deter future attacks but also contributes to a more secure digital ecosystem for all.

For merchants concerned about the breach, Checkout.com’s support lines remain open, providing resources and answers to specific questions. This level of dedication to customer service during a crisis is essential in reassuring partners of the company’s commitment to safeguarding their interests.
