What Pegasus is
Pegasus is spyware made by a company called NSO Group. It is sold to government agencies, not to ordinary criminals or the public. Once it lands on a phone, it can read messages, photos, notes and location, and can even switch on the microphone or camera. In short, it sees what your phone sees.
What “zero-click” means
Most attacks need you to make a mistake — tap a bad link, open a fake file. A zero-click attack skips that step. It arrives through something your phone handles automatically, like a message, and installs quietly with nothing for you to notice.
That sounds frightening, but it is also why these attacks are so valuable and so limited: they cost a great deal to build and are spent on carefully chosen targets. This is different from everyday malware like an infostealer, which is scattered widely and relies on you installing something.
Who is actually targeted
In case after case, the people found with Pegasus on their phones are journalists, activists, lawyers and political figures. The recent finding that prompted this article was on the phone of a student activist in Serbia, discovered by researchers at Citizen Lab together with the SHARE Foundation.
If you are not in a group that a government wants to watch, the practical risk to you is very low. This is worth saying plainly, because the goal here is calm, not fear.
The honest limit of any vault
Here is the part we will always be straight about. An encrypted vault protects your files while they are locked away. But if a phone is fully taken over by spyware, the attacker can see things at the moment you see them — while the vault is open and you are looking at a photo or note.
No app can fully protect an unlocked screen on a phone that is already compromised. That is why the steps below, which keep spyware off the phone in the first place, matter more than any single app.
The free steps that help
Everything here is built into your iPhone and costs nothing. Keep iOS updated — these attacks depend on flaws that Apple patches, and the exploit in the recent case was closed by an update Apple shipped in 2025. Updating promptly is the single most effective thing you can do.
If you are an activist, journalist or someone who may be targeted, turn on Lockdown Mode. It is in Settings and it deliberately switches off some of the features these attacks abuse. It is not for everyone, but it is powerful for those at risk. Turning on Advanced Data Protection for iCloud is a sensible companion step for keeping your backups end-to-end encrypted.
Take Apple Threat Notifications seriously: if you ever get one, it is real — follow its advice and seek help from a group like Access Now’s Digital Security Helpline. And restart your phone now and then; some spyware does not survive a reboot, so it is a small habit with a real benefit.
Where Sealby fits
Sealby cannot stop a government-grade attack on your phone’s operating system, and we will never pretend otherwise — the defences that matter most against Pegasus are keeping your phone updated and, for those at risk, Lockdown Mode. What Sealby does is give your most sensitive photos, videos, notes and files a home of their own: encrypted on your device, opened only with your own PIN or passphrase, and kept out of the shared camera roll that ordinary apps can see. It is one honest layer among several — not a magic shield, and we would rather tell you that than sell you a false sense of safety.
This is general education, not security advice. Threats, tools and app features change over time and differ by device — check current, reputable sources and the settings on your own device.
