Google says over 100 firms likely hit in Oracle-linked hacking campaign

Google warned that more than 100 companies may have been compromised in a massive cyberattack targeting Oracle’s E-Business Suite, a core system used by corporations to manage supply chains, customer data, and manufacturing operations.

In a statement released Thursday, Google said “mass amounts of customer data” were stolen in the attack, which may have begun three months ago. The company attributed the breach to the CL0P ransomware group, known for large-scale cyber intrusions exploiting third-party software vulnerabilities.

“This level of investment suggests the threat actor dedicated significant resources to pre-attack research,” Google’s cybersecurity division said. Analyst Austin Larsen added that while dozens of victims have been confirmed, “based on the scale of previous CL0P campaigns, it is likely there are over a hundred.”

The breach appears to have targeted Oracle’s E-Business Suite, used by corporations worldwide to manage sensitive operations including logistics, customer relations, and payments. Oracle has not publicly commented beyond acknowledging ongoing extortion attempts against some clients.

CL0P, which has previously claimed responsibility for major data thefts, told Reuters earlier this week that Oracle had “bugged up their core product.” The group is reportedly threatening to publish stolen data unless ransom demands are met.

Cyber experts say the scale of the attack could rival the MOVEit hack of 2023, underlining the growing risk of supply chain breaches that exploit trusted enterprise software systems.
