The DragonForce ransomware group claims to have breached SINBON Electronics Co., Ltd., a leading Taiwanese manufacturer of electronic components known for partnering with major firms like ASML Holding N.V. The group alleges they have exfiltrated over 847 GB of data from the company’s network.
This data leak announcement directly disputes a recent official statement SINBON reportedly filed with the Taiwan Stock Exchange. While the company stated the attack was quickly blocked with no data loss, DragonForce asserts this is inaccurate. The attackers claim the intrusion persisted for several weeks, impacting both the Taiwanese headquarters and the U.S. subsidiary, and accuse the company’s IT staff of attempting to conceal the true scale of the breach from regulators and senior management.
According to the actor, the allegedly compromised data includes roughly 650,000 files totaling 847.32 GB. The leaked dataset purportedly contains:
-
Financial and accounting records
-
Client data and personal information
-
Documentation of collaboration with ASML Holding N.V.
-
Production records
-
Detailed evidence of product defects
-
Reports on the company’s financial condition
