Ransomware suspected – but unconfirmed – in debilitating assault

UPDATED Israeli chipmaker Tower Semiconductor has suspended some of its operations and taken servers offline in response to a cyber-attack.

“Tower has notified relevant authorities and is working closely with law enforcement organizations and with a leading team of worldwide experts, coordinated with its insurance providers, in order to recover the impacted systems as soon as possible,” the firm said in a statement issued on Sunday (September 6).

“The company has implemented specific measures to prevent the expansion of this event,” it added.

The extent and cause of the disruption – much less how costly it might prove to be – remains unclear.

In a brief holding statement, the company said that it had “halted certain of its servers and proactively held operations in some of its manufacturing facilities, and has done so in a gradual, organized manner”.

In response to questions from The Daily Swig, Tower Semiconductor described local reports it had suffered a ransomware-based attack as speculative without denying them outright.

The chipmaker said: "Our first priority to resume operations. We will notify publicly once this milestone [is] achieved."

"At this point, there is no assessment as to the actual financial effect on the company."

A spokesperson for the vendor added that reports is was claiming on its insurance following a ransomware infection is "based on the reporter speculations".

Tower Semiconductor specializes in the fabrication of analogue integrated circuits that find application in multiple verticals including automotive, medical, aerospace and defense.
