NoReboot: A fake restart to gain a foothold in the systemĭisable iMessage. The attackers tried to target them a few more times but eventually gave up after getting kicked a few times through reboots. The device owner rebooted their device regularly and did so in the next 24 hours following the attack. Actually, this is not just theory, it’s practice - we analyzed one case in which a mobile device was targeted through a zero-click exploit (likely FORCEDENTRY). In time, this increases the chances of detection a crash might happen or artifacts could be logged that give away the stealthy nature of the infection. If the device is rebooted daily, the attackers will have to re-infect it over and over again. According to research from Amnesty International and Citizen Lab, the Pegasus infection chain often relies on zero-click 0-days with no persistence, so regular reboot helps clean the device. How to protect from advanced spyware on iOS How do we do this in practice? Here’s a simple checklist. Although we may not always be able to prevent the successful exploitation and infection of the mobile device, we can try to make it as hard as possible for the attackers. With that in mind, infection and targeting is also a question of cost and making things more difficult for the attackers. Exploits need to be tuned for specific OS versions and hardware and can be easily thwarted by new OS releases, new mitigation techniques or even small things such as random events. Now, for the good news - exploit development and offensive cyberwarfare are often more of an art rather than an exact science. To put this in simpler words, if you are targeted by such an actor, it’s not a question of “whether you can get infected,” it’s actually just a matter of time and resources before you get infected. When a threat actor can afford to spend millions, potentially tens of millions or even hundreds of millions of USD on their offensive programs, it is very unlikely that a target will be able to avoid getting infected. These are extremely expensive - as an example, Zerodium, an exploit brokerage firm pays up to $2.5 million for an Android zero-click infection chain with persistence:įrom the start, this draws an important conclusion - nation state sponsored cyberespionage is a vastly resourceful endeavor. Similarly, other APT mobile malware may be deployed through zero-click 0-day exploits. The cost of a full deployment may easily reach millions of USD. How to stay safe from Pegasus and other advanced mobile spywareįirst of all, we should start by saying that Pegasus is a toolkit sold to nation states at relatively high prices. Additionally, as attackers change their modus operandi, protection techniques should also be adapted. We are trying to address this in the current article, with the observation that no list of defence techniques can ever be exhaustive. Over the past few months I have received a lot of questions from concerned users worldwide on how to protect their mobile devices from Pegasus and other similar tools and malware. Apple announced, in November, that it was taking legal action against NSO Group for developing software that targets its users with “malicious malware and spyware.” Last but not least, in December, Reuters published that US State Department phones were hacked with the NSO Pegasus malware, as alerted by Apple. In October, India’s Supreme Court commissioned a technical committee to investigate the use of Pegasus to spy on its citizens. Later in July, representatives from the Israeli government visited the offices of NSO as part of an investigation into the claims. The list of targeted individuals includes 14 world leaders and many other activists, human rights advocates, dissidents and opposition figures. The report, called the Pegasus Project, alleged that the malware was deployed widely through a variety of exploits, including several iOS zero-click zero-days.īased on forensic analysis of numerous mobile devices, Amnesty International’s Security Lab found that the software was repeatedly used in an abusive manner for surveillance. Pegasus is a so-called “legal surveillance software” developed by the Israeli company NSO. Possibly the biggest story of 2021 - an investigation by the Guardian and 16 other media organizations, published in July - suggested that over 30,000 human rights activists, journalists and lawyers across the world may have been targeted using Pegasus.
