Can Chromebooks Be Hacked and How to Keep Your Data Safe

Chromebooks are a popular choice for those looking for a budget-friendly and user-friendly laptop option. They're designed to be secure, but like any device connected to the internet, they're not completely immune to hacking.

Chromebooks run on Google's Chrome OS, which is built with security in mind, with regular automatic updates and a sandboxed environment that isolates apps and data. However, this doesn't mean they're completely hack-proof.

One of the most significant risks to Chromebook security is malware, which can be downloaded through malicious websites or infected apps.

Chromebooks can be hacked, and it's not just a theoretical risk. Several districts in the United States have experienced high-profile cyberattacks in recent years.

Phishing, ransomware, and compromised third-party apps are common tactics used by cyber-criminals. Students have exploited weak admin controls to bypass content filters or access teacher accounts.

In one particularly concerning case, a compromised student account led to ransomware being deployed through shared documents, locking up not only student files but also administrative systems.

Here's how hackers can break into your Chromebook:

They can exploit vulnerabilities in the Chrome OS operating system, just like they do with Windows and macOS.

Using phishing scams, hackers can trick you into giving them your login credentials, which they can then use to access your Chromebook.

Hackers can also use malware to infect your Chromebook, which can give them control over your device.

They can break into your Chromebook if they have your password, especially if it's a weak one that's easily guessable.

Weak passwords can be cracked using brute-force attacks, which involve trying millions of different combinations until the correct one is found.

Chromebooks are not completely immune to malware, despite their robust security features. Chrome OS closes off most traditional entry points for malware, but an adversary can still exploit features of Chrome OS or your brain for ill purposes.

A hostile page can still lock up your browser and demand payment, and you can escape this by resetting your Chromebook and restarting Chrome while declining its option to restore earlier open pages. This is a common tactic used in malicious advertising campaigns that trick or force users to install bogus extensions.

Malwarebytes' lead malware-intelligence analyst, Jérôme Segura, has seen an increase in malicious advertising campaigns that download malicious extensions over a thousand times before they're removed from the Chrome Web Store. This is a concerning trend that highlights the need for vigilance.

The ability of Chrome OS to run Android apps adds a low but non-zero possibility of infection, as Android malware can sweep across phones in vast quantities. However, it's worth noting that most Android malware arrives via third-party app stores, not Google's Play Store.

In recent years, several districts in the United States have experienced high-profile cyberattacks, many of which involved phishing, ransomware, or compromised third-party apps. Students have exploited weak admin controls to bypass content filters or access teacher accounts, and some have even altered grading portals or spread malware across shared drives.

The education sector has become a top target for cyber-criminals globally, not because it's profitable, but because it's often undersecured. Many schools operate on shoestring IT budgets with overburdened tech staff and outdated policies, making them attractive and easy prey.

Chromebooks have a robust security system that makes them difficult to hack. Chrome OS uses a principle called "defense in depth" where multiple layers of protection work together to keep hackers at bay.

One of these layers is sandboxing, which isolates processes so that malware in one tab or app cannot easily spread or access other parts of the system. This means that even if a Chromebook is infected with malware, it's unlikely to spread to other parts of the system.

Chromebooks also have verified boot, which checks the integrity of the system every time it starts up and reverts to a safe version if anything suspicious is found. This ensures that the system is always in a secure state.

Automatic updates are another security feature that keeps Chromebooks safe. Chrome OS downloads and installs its own security updates automatically, so you don't have to worry about keeping your Chromebook up to date.

Even if a Chromebook is lost or stolen, the data stored on it is relatively safe. Chromebooks store data online, so even if the device is compromised, the data is still secure.

However, it's worth noting that Chromebooks are not completely foolproof. Malicious or poorly vetted browser extensions can request excessive permissions, intercept browsing data, or even act as keyloggers.

Chromebooks are relatively safe from malware due to the security features built into Chrome OS, which closes off most traditional entry points for malware.

You can't install traditional programs on a Chromebook, and the browser and individual pages run locked inside "sandboxed" areas of memory.

Chrome OS automatically downloads and installs its own security updates, and stores your data online, so even if you set a Chromebook on fire, your info should be safe.

However, an adversary can still exploit features of Chrome OS, and of your brain, for ill purposes.

A hostile page can still try to lock up your browser and leave it stuck on a demand that you pay up, but you can escape that by resetting the Chromebook, then restarting Chrome while declining its option to restore earlier open pages.

Malicious third-party extensions can be installed, which can lead to page hijacking and tricking users into installing bogus extensions.

Last year, one such extension was downloaded over a thousand times before Google yanked it from the Chrome Web Store.

The newfound ability of Chrome OS to run Android apps adds a low but non-zero possibility of infection, although most Android malware arrives via third-party app stores, not Google's Play Store.

Chromebooks use a series of protection layers, one on top of the other, to keep hackers at bay, a principle known as "defense in depth."

This multi-layered approach makes it extremely difficult for hackers to breach Chromebook security.

Chrome OS closes off most traditional entry points for malware, which reduces the "attack surface" of Chromebooks.

You can't install traditional programs at all, and the browser and individual pages run locked inside "sandboxed" areas of memory.

Chrome OS also downloads and installs its own security updates automatically, ensuring you're always running the latest and most secure ChromeOS version.

At each reboot, a Chromebook verifies that its software hasn't been tampered with and repairs it if necessary.

This level of security makes it unlikely that you'll hear about successful hacking attacks on Chromebooks in the media.

Your Chromebook is designed to fend off hackers' attacks, making it a true fortress of security.

However, an adversary can still exploit features of Chrome OS and your browser for ill purposes.

A hostile page can lock up your browser and demand payment, but you can escape this by resetting the Chromebook and restarting Chrome while declining to restore earlier open pages.

This is a common tactic used in malicious advertising campaigns, also known as malvertising.

Malicious third-party extensions can be installed by tricking or forcing users to do so, and these extensions can run inside of Chrome.

One such extension was downloaded over a thousand times before Google removed it from the Chrome Web Store.

The ability of Chrome OS to run Android apps, which is confined to a few recent Chromebooks, adds a low but non-zero possibility of infection.

Android malware can sweep across phones in vast quantities, often arriving via third-party app stores.
