We increasingly store our lives, both work and personal, on our devices. Laptops, phones, tablets: all of those hold everything from confidential work documents to personal memories and login credentials. That makes them highly valuable targets for attackers, especially when a device is physically stolen.

So how do attackers exploit stolen devices, and what can you do to protect yourself?

### Three common attack paths:

#### 1. Unlocked & unattended devices

This is the simplest, and unfortunately, one of the most common attack scenarios.

If you leave your laptop open and unattended, even for just a moment, an attacker can plug in a malicious USB device that emulates a keyboard. These tools can inject keystrokes at lightning speed to run scripts, open backdoors, or install malware, often in under 10 seconds.

No technical exploit required. No passwords to bypass. Just an open window of opportunity.

**Tip:** Always lock your device, even if you're stepping away for a moment

#### 2. Unencrypted devices

Encryption is one of the most critical safeguards for your data. While many modern operating systems offer built-in encryption, it's not always enabled unless you explicitly set it up, and unless your device automatically locks when you step away, that encryption might not protect you in time. Just setting a login password isn't the same, because if your device isn’t encrypted, all someone needs to do is take the drive out.

Here’s a typical attack scenario:

- The attacker steals the device (e.g., from a bag or left unattended).
- The device is powered off.
- The attacker removes the hard drive.
- They plug it into another machine like a USB stick.

If the disk is **not encrypted**, all your files, like documents, photos, saved passwords, are now fully accessible. No password is needed.

**Good news:** You can check and enable encryption in your device settings. Tools like the **XFA** make this easy, helping you verify whether your device is properly protected.

#### 3. Exploiting locked or encrypted devices through OS/Firmware vulnerabilities

While the second method involves physically removing the hard drive from a device, often requiring screws to be removed or the device to be broken open, there’s a more subtle and technical route attackers can take: exploiting weaknesses in how a system handles credentials in memory.

In this scenario, the attacker targets vulnerabilities in an **out-of-date operating system or firmware**, especially when the device is still powered on or in sleep mode.

In addition, some older systems store login credentials or even full-disk decryption keys in memory in ways that can be retrieved through specialized exploits. This is especially true if the device uses outdated versions of hardware components like the **TPM (Trusted Platform Module) chip**, which is responsible for managing encryption keys and authentication.

A more advanced scenario might look like this:

- You leave your laptop unattended and locked, maybe in sleep mode.
- A hacker finds the device while it's still powered on or in standby.
- They insert a specially prepared USB stick.
- The USB contains malware that targets a vulnerability.
- The exploit extracts data directly.

Once access is gained, the attacker can:

- Steal specific files.
- Install malware.
- Or simply take the device permanently.

### How to protect yourself

You can significantly reduce your risk by following a few best practices:

- **Encrypt your device.** Make sure full-disk encryption is enabled.
- **Keep your operating system and firmware updated.** Many attacks rely on known vulnerabilities that patches fix.
- **Put a password on your device.**
- **Enable auto lock on your device**, or **lock the device when you walk away.**
- **Power down your device** when not in use, rather than just putting it to sleep. A powered-down, encrypted device is much harder to exploit.

### How XFA can help

Understanding these attack scenarios is the first step, **protecting against them** is the next. That’s where XFA comes in.

XFA helps you proactively detect devices that your team uses, inform them about these practices and even enforce them before they’re allowed to use the device for work. Here’s how it helps guard against the scenarios above:

- **Checks if your device is encrypted, has a password, and auto locks.**
- **Verifies your operating system and firmware are up to date.**
- **Detects missing security settings or potential vulnerabilities.**
