The attackers used convincingly crafted phishing emails and spoofed internal communication channels, aiming to bypass multifactor authentication defenses. Advanced phishing toolkits and session hijacking techniques were identified as part of the adversary’s arsenal, allowing them to escalate privileges rapidly once initial access was achieved.
Remediation and Security Lessons
DoorDash accelerated implementation of additional user access protections, including enhanced phishing-resistant authentication, mandatory security awareness campaigns, and tighter API security controls. The breach illustrates the continuing evolution of social engineering tradecraft amid growing employee security awareness, and the ongoing need for layered human-centric defenses.
Cl0p Ransomware Targets Oracle E-Business Suite: Broad Exploitation of CVE-2025-61882
Nearly 30 organizations, from major media outlets to universities, were publicly named by the Cl0p ransomware group as victims of a deliberate campaign exploiting a zero-day vulnerability in Oracle E-Business Suite (EBS). The attack resulted in the exposure of sensitive information for up to 10,000 entities, raising significant concerns about enterprise software supply chain security and patch management practices.
Vulnerability Details and Attack Mechanism
The campaign exploited CVE-2025-61882, a critical vulnerability in Oracle EBS versions 12.2.3 through 12.2.14, which allowed unauthenticated attackers to achieve remote code execution. Attackers leveraged this flaw to gain deep lateral access within corporate environments, deploy ransomware payloads, and exfiltrate large volumes of data before initiating encryption routines.
Key victims included The Washington Post, Logitech, Harvard University, Cox Enterprises, and Pan American Silver. The attackers contacted victims directly to demand payment, and in some cases, published proof of access to sensitive files to extort compliance.
Forensics and Defense Strategies
Organizations affected by the zero-day typically faced limited detection capability, as the exploit pathway bypassed standard intrusion prevention systems and did not require social engineering to succeed. Incident response included emergency patching, deployment of endpoint detection and response (EDR) tools to track lateral movement, and enhanced network segmentation to contain the impact.
