Fast Facts

• ShinyHunters, a notorious hacker group, claimed to breach Checkout.com’s old cloud storage and demanded ransom.
• The compromised data came from an outdated archive, not the live payment platform.
• No payment credentials or merchant funds were exposed in the incident.
• Checkout.com refused to pay the ransom, instead donating equivalent funds to cybersecurity research at Carnegie Mellon and Oxford.
• The company is contacting affected clients and cooperating with authorities.

When Hackers Knock, Will You Pay or Fight Back?

Imagine a locked vault in a forgotten wing of a digital fortress. One day, a shadowy figure finds a rusted key, slips inside, and leaves a ransom note. For Checkout.com, a global payments processor, this metaphor became reality in November 2025, when the ShinyHunters hacking collective claimed to have breached an old cloud storage system and demanded payment to keep quiet.

The story is a cautionary tale about how even the most sophisticated companies can be tripped up by yesterday’s technology. The hackers didn’t crack the main vault; instead, they found an unlocked side door - an obsolete cloud archive, no longer in use since before 2020, but never properly shut down. Inside were internal documents, onboarding materials, and organizational files - not the payment data or merchant funds that fuel Checkout.com’s global engine.

Hackers, Ransom, and a Reversal of Fortunes

Ransomware attacks and digital extortion have become the underworld’s business model of choice in recent years. Groups like ShinyHunters have made headlines for selling stolen data and shaking down companies from telecoms to universities. In 2020, ShinyHunters claimed responsibility for attacks on Tokopedia, Microsoft, and Wishbone, often targeting cloud storage and legacy systems - where companies are most vulnerable.

But Checkout.com’s response was a rare twist: they refused to pay a single cent to the extortionists, and instead pledged an equivalent sum to academic cybercrime research. The recipients? Prestigious labs at Carnegie Mellon and Oxford, institutions at the front lines of studying - and thwarting - digital criminality. It’s a move that transforms a moment of weakness into an act of resistance, turning ransom money into ammunition for the good guys.

Lessons from the Breach: Transparency and Trust

Checkout.com’s leadership took full responsibility, admitting the old storage should have been decommissioned sooner. They quickly began notifying affected clients - estimated at less than a quarter of their active base - and are working closely with regulators and law enforcement. The company emphasized that their payment infrastructure, the crown jewels, remained untouched: no card credentials or merchant access were put at risk.

This incident is a stark reminder that in cybersecurity, the past is never truly past. Forgotten systems are like unguarded back doors, waiting for someone to try the handle. The market lesson is clear: as digital extortion grows ever more lucrative, companies must be as vigilant about their history as they are about their present.

• Cloud Storage: Cloud storage is an online service that saves your files and data remotely, letting you access them anytime from any internet-connected device.
• Legacy System: A legacy system is outdated software or hardware still in use because replacing or upgrading it is difficult, costly, or disruptive.
• Data Breach: A data breach is when unauthorized parties access or steal private data from an organization, often leading to exposure of sensitive or confidential information.
• Extortionware: Extortionware is a cyberattack where criminals threaten to leak stolen data unless the victim pays a ransom or meets their demands.
