Could my power bank or Bluetooth accessories carry malware to my new devices?
Asked by

I recently escaped a frightening situation involving someone with software-engineering experience who allegedly sent malware to my phone and computer, accessed my home, and may have tampered with my belongings. I changed my passwords and replaced my phone, and I'm having the old laptop examined by a technician. I also checked my car and belongings for trackers and cameras.
I'm worried that some accessories might be compromised and could infect my replacement devices. In particular, could an IKEA power bank, JBL Bluetooth headphones, or a Bluetooth mouse contain malware that spreads to a new phone or laptop? I want to be careful without throwing away everything unnecessarily.

A malicious USB device is technically possible, but a reputable, ordinary power bank is not a realistic source of infection in normal use. For extra caution, charge the new phone and laptop with a wall charger and cable you trust, and avoid plugging unknown USB devices into them. Bluetooth accessories should be reset, updated using the manufacturer’s official app, and paired only after removing old pairings. Keep Bluetooth off when you aren’t using it.

Those accessories are very unlikely to contain ordinary phone or computer malware. A normal power bank generally only supplies power, and Bluetooth headphones or a mouse do not normally have the permissions needed to infect a paired device. Deliberately compromising their firmware would be unusual and require specialized access. The old laptop and phone are the devices that deserve careful examination, so don’t connect them to your new equipment until they’ve been checked.

If a phone still appears compromised after a factory reset, it’s worth having a qualified mobile-security specialist verify what happened rather than assuming the accessories caused it. Make sure the phone is updated, install apps only from the official store, review account sessions and recovery methods, and enable multi-factor authentication. Also consider reporting the stalking and break-in to local authorities or a victim-support organization; a translator or interpreter may be available even if you aren’t fluent in the local language.
LunarTeapot39: A factory reset normally removes ordinary apps and malware, although rare firmware or account-level problems can complicate things. Don’t reuse backups or automatically restore every app until the accounts and old devices have been reviewed.

MellowPine47: That’s reassuring. I’m mainly worried because I don’t know what kinds of attacks are possible, so I’d rather separate the old devices until a technician looks at them.
