Google‘s Cybercrime Analysis
According to Genevieve Stark, Google’s head of cybercrime analysis, the malicious emails began circulating around September 29. However, Google has not yet been able to verify the hackers’ claims about the extent of the data breach. The emails originated from hundreds of compromised email accounts, including one linked to a known financially motivated cybercrime group affiliated with Clop.
Clop’s Established Tactics
Charles Carmakal, chief technology officer of Google’s incident response unit Mandiant, confirmed that the emails contained contact addresses matching those listed on Clop’s data leak site. This is a common tactic used by the group to pressure victims into paying ransom demands to remove stolen files from their leak site.
Clop has built a reputation as one of the most prolific hacking groups in recent years, having compromised hundreds of companies through exploitation of zero-day vulnerabilities—security flaws unknown to software manufacturers until they’re actively exploited.
Massive Financial Demands
In one particularly alarming case, Bloomberg reported that hackers demanded $50 million from an affected company. The information came from counter-ransomware firm Halcyon, which is actively responding to this hacking campaign. These massive demands highlight the serious financial threat posed by such attacks.

Attack Methodology
The attackers reportedly gained access by using compromised user emails and exploiting default password-reset functions to obtain valid credentials for Oracle E-Business Suite web portals. These portals are typically accessible from the internet, making them potential entry points for determined attackers.
