A reported cyberattack focusing on Oracle Cloud has raised issues about potential knowledge publicity throughout a variety of organisations.
On March 21, cybersecurity agency CloudSEK stated that 6 million data had been compromised, with over 140,000 Oracle Cloud tenants presumably affected.
CloudSEK attributed the incident to a risk actor recognized as “rose87168,” who allegedly obtained the information by means of Oracle’s Single Signal-On (SSO) and Light-weight Listing Entry Protocol (LDAP) methods. The attacker has listed the data on the market on-line and is reportedly demanding cost from affected corporations for knowledge removing.

CloudSEK has rated the risk as “Excessive” because of its reported scale and the sensitivity of the information concerned.
CloudSEK’s response and suggestions
The cybersecurity agency has really useful that organisations utilizing Oracle Cloud take fast actions, resembling resetting credentials, launching forensic investigations, monitoring for leaked knowledge on the darkish net, and making use of stricter entry controls.
CloudSEK additional warned that if the encrypted credentials are efficiently deciphered, there might be far-reaching penalties, like unauthorised entry, potential knowledge leaks, and dangers to linked methods throughout provide chains.

The corporate’s response adopted on-line exercise by the risk actor, who posted samples of what was claimed to be stolen Oracle Cloud knowledge on cybercrime boards, together with screenshots and a textual content file uploaded to one in all Oracle’s login servers. The file contained an e mail handle related to the vendor and was captured by the Web Archive’s Wayback Machine.
Whereas Oracle has not commented additional, investigations by third events, together with Bleeping Pc, famous that one of many affected servers was reportedly working an older model of Oracle Fusion Middleware as not too long ago as February 2025. Safety researchers have speculated that an unpatched important vulnerability—CVE-2021-35587—might have been concerned, though this has not been confirmed.
Ongoing uncertainty round claims
