Moxy Marlinspike, founder and director of the “Signal” instant messaging service, revealed that he had hacked a device used by the Israeli company, “Cellebrite”, which specializes in hacking smartphones for intelligence purposes.
In a post on the official website of Signal, Moxy indicated that the “Silbright” device, which was found by accident, contains security flaws that expose the Israeli company’s customers to danger and threaten the accuracy of the reports issued by the devices used to penetrate phones.
The post indicated that there are a number of flaws in the software system for operating the “Celebright” device, and Moxy considered them to be “high-risk” loopholes capable of making the Israeli company warn its customers against using its devices to extract information from inside any smartphone.
Moxy pointed out that some of the discovered vulnerabilities are able to open the way for hackers to place malicious code inside the operating system of the “Silbright” device, by planting a malicious file inside one of the applications installed on the target phones.
Through the malicious programming, it becomes easy for the hacker to remotely control the data and files stored on the phones, and thus it is easy to tamper with the reports issued by the “Celebright” devices, and the security services, which are considered one of the most important customers of the Israeli company, depend on them.
This statement comes as a new episode in which Signal responds to the allegations made by the company, “Silbright”, which it launched last month, during which it stated that it is able to provide services to hack any account on the “Signal” service to its customers.
Signal’s statement included a response “to this allegation,” noting that what Silbright can do in terms of collecting data from a Signal account, is what anyone can do when they hold a phone in their hands with an unlocked screen lock, and the only feature it provides “Celebright” for its customers to perform this operation automatically, without human intervention.
