Google Pixel 2 devices are vulnerable to a hack developed by a spyware dealer in Israel. Hundreds of millions of devices are likely vulnerable, given Huawei P20 and Samsung S8 and S9 models are also affected, a Google researcher warned.
Google issued an alert overnight about a fresh vulnerability affecting hundreds of millions of Android phones, including its own Pixel 2. According to Google security researcher Maddie Stone, the weakness is actively being used against targets of the Israeli spyware dealer NSO Group.
If you own any of the following phones, your device likely remains vulnerable today as patches are not yet available: the Google Pixel 2, Huawei P20. Xiaomi Redmi 5A, Xiaomi Redmi Note 5. Xiaomi A1, Moto Z3, Oreo LG phones and the Samsung S7, S8, S9 models. Those are some of the most popular Android phones in existence today. Huawei has shipped over 16 million P20 smartphones around the world, according to the Chinese company’s figures from the end of 2018.
Stone said the underlying issue was fixed in Android way back in December 2017, but “the Pixel 2 with most recent security bulletin is still vulnerable based on source code review.” The same is true for all those other Android phones, though Google didn’t explain why the patches didn’t prevent the latest exploits from working. Google also didn’t note why it had attributed the hacks to NSO Group.
A bug explained and squished (soon)
The problem was defined by Stone as a kernel privilege escalation bug, which means it provided a way for a hacker who’d already found a way onto the device to get deeper access, right into the heart of the Android operating system. Getting control of the kernel allows a hacker to do almost whatever they like on the phone, grabbing much of the data within. Whoever was exploiting the vulnerability would’ve likely used other bugs, combining them in what’s known as an “exploit chain” to completely own an Android device remotely. That is, after all, what NSO trades in; it’s built a reputation for being able to remote target and takeover smartphones but its reported sales of this technology to Mexico and the U.A.E. has put it at the centre of a storm over privacy and surveillance.
As Stone noted, if the hack was delivered via the web, it would’ve only required one other kind of exploit. Just last month, similar attacks were launched in China, as Uighur-focused websites were hacked and used to infect iPhone and Android smartphones that landed the on pages.
“The bug is a local privilege escalation vulnerability that allows for a full compromise of a vulnerable device. If the exploit is delivered via the web, it only needs to be paired with a renderer exploit, as this vulnerability is accessible through the sandbox,” Stone wrote in a post on Thursday.
Tim Willis, a manager at Google’s Project Zero security research team, noted the issue was rated as “high severity,” adding that a malicious application could also be used to launch an attack via the vulnerability.
A patch for Pixel users are at least on the way. A Google spokesperson added: “Pixel 3 and 3a devices are not vulnerable to this issue, and Pixel 1 and 2 devices will be protected with the October Security Release, which will be delivered in the coming days. Additionally, a patch has been made available to partners in order to ensure the Android ecosystem is protected against this issue”
NSO Group is one of many Israeli startups whose modus operandi is to hack into the world’s most-used operating systems for nation state intelligence and police agencies. On Thursday, Forbes disclosed details on one of the youngest members of that secretive community, Candiru, which one researcher believes is selling to various regimes, including Saudi Arabia, the U.A.E. and Uzbekistan.
These firms have faced a backlash over their authoritarian client book following revelations that their tools were allegedly used to spy and track activists, journalists and human rights lawyers around the world. As Forbes revealed last year, various Saudi activists, some closely associated with murdered journalist Jamal Khashoggi, were targeted by NSO tools. NSO later denied having anything to do with Khashoggi’s death.
NSO had not responded to a request for comment on this latest issue at the time of publication.
