In a blog post posted on Wednesday, it was suggested that Israel can easily be sabotaged by encrypted chat app Signal to law enforcement from Israeli surveillance provider Cellebrite. CellebriteCellebrite DI Ltd, which specializes in helping law enforcement and intelligence agencies copy call logs, texts, photos and other data off smartphones, has come under fire for previous sales to authoritarian governments, including Russia and China. Cellebrite, a privacy-focused app eager to show the lengths it goes to protect user conversations, clashed with SignSignal last year when the Israeli company said its equipment was upgraded to allow law enforcement to pick up Signal messages from devices in their possession. On Wednesday, the Signal creator Moxie MarlinspikeMarlinspike said in his blog post he came into possession of a Cellebrite bag and examined the gear inside. He was surprised to find that very little care seems to have been given to the propriety of Cellebrite, Marlinspike said, noting that it would be easy to add a specially crafted file onto a phone that would derail Cellebrite's functionality. He said in his blog post that he had found snippets of code from AppleApple Inc within Cellebrite's software, something he said could present a legal risk for Cellebrite and its users if it was done without permission. Signal did not immediately respond to a request for comment; Apple's allegations come as Cellebrite prepares to go public through a merger with a blank-check firm, which valuates the equity of the combined company at around $2.4 billion.
