has confirmed that some users of its E-Business Suite software have received extortion emails from hackers, validating a warning first issued by Google earlier this week. In a Thursday blog post, the California-based tech giant said its internal investigation revealed potential exploitation of previously known software vulnerabilities and urged customers to upgrade their systems immediately.
The company did not specify how many clients were impacted, but Google described the campaign as “high volume”, suggesting a broad wave of attacks against enterprise users.
Cybersecurity experts have linked the operation to the ransomware group Cl0p, a notorious Russia-linked or Russian-speaking collective that operates under a ransomware-as-a-service model—leasing its malware tools to other cybercriminals for a share of the profits. In a message to Reuters, the group said “Oracle bugged up,” but declined to provide further details.
According to Halcyon’s Ransomware Research Center chief Cynthia Kaiser, recent extortion demands connected to the campaign range from millions to tens of millions of dollars, with the highest reaching $50 million.
Trend Micro, a Japanese cybersecurity firm, previously labeled Cl0p as a “trendsetter for its ever-changing tactics,” noting its rapid adaptation to new vulnerabilities and defenses.
The attacks come amid a surge in corporate cyber-extortion incidents, targeting firms with complex enterprise software systems that handle sensitive financial and operational data. Oracle’s swift public acknowledgment—unusual in such cases—signals the seriousness of the threat and the company’s attempt to reassure customers that patches and updates remain their best defense.
