Self-scans reveal that Pegasus, an invasive and powerful spyware that can secretly control phones and track owners, might be more widespread than previously thought. It was discovered on the phones of everyday phone users.
I haven't checked, does GrapheneOS do reproducible/deterministic builds so that you could verify that the published release matches your image? The boot attestation should not be able to be circumvented, if you trust Google hardware to do what it says on the tin.
It worked with antivirus scanning - more than half of Windows PCs have spyware on them their users consciously installed so that it would scan and report what they run.
That's outdated stuff. Pegasus doesn't need phishing methods to get on your phone. It just installs itself when an actor sends it your way. You won't notice it and the only way to prevent it is to not use a phone.
It technically uses various zero-day zero-click exploits to get there. Which is why it functions like a service - they need to maintain relevance of those exploits. Imagine, a whole service of clearly illegal activity, which doesn't get absolutely destroyed simply because it's useful to spy on dissidents.
Amnesty International provides a FOSS tool to check your mobile backups for traces of the Pegasus Spyware. I’d trust that over a sketchy proprietary app. Link: https://docs.mvt.re.
MVT is a forensic research tool intended for technologists and investigators. Using it requires understanding the basics of forensic analysis and using command-line tools. MVT is not intended for end-user self-assessment. If you are concerned with the security of your device please seek expert assistance.
It can help you if you think you are BUT especially with iPhones it can only scan your backup, unless you jailbreak the phone and can do a full disk dump.
As a mobile security expert this is just one of the tools in the kit, but it ought not be used by a “end user” as a verification tool. This does NOT verify you aren’t being tracked, it can only verify that signatures of the malware exist.
Everyone is safe from Pegasus ...
Except cell phone owners (which is most everyone)
Exception to the exception : people who know about this excellent FOOS tool (and know someone who can use it) - - thanks
I don't know the full answer, but Pegasus isn't one single piece of spyware, but rather a toolkit of many, many zero-day exploits.
A lot of them (the majority maybe?) are non-persistent meaning that they don't survive a reboot.
That said, aside from keeping your phone up to date with security patches and rebooting frequently, I'm not sure there's much the average person can do if you're actively being targeted.
I installed GrapheneOS the moment I got my phone, which should give me a few protections over standard Android.
Longer term, I intend to get a Linux phone, I'm just waiting for the hardware and software to improve. I already almost entirely avoid the Play store, so making the final switch shouldn't be that big of a jump.
I'd be careful about completely trusting any AV to give you any certainty that you aren't infected.
As I mentioned in another comment, Pegasus is comprised of many different exploits. So just because Bitdefender can detect some older Pegasus variants, doesn't mean it can detect all of them.
In fact it's quite unlikely they can detect the latest variants.
