Here\u2019s how it works, what the risks are, and how to tell if you're vulnerable:\n\n---\n\n## \u26a0\ufe0f How it could happen\n\nA well-known class of attacks \u2014 called **MouseJack** and **KeySniffer** \u2014 exploits vulnerabilities in many wireless keyboards and mice that use 2.4 GHz RF dongles instead of Bluetooth. ([wired.com](https://www.wired.com/2016/02/flaws-in-wireless-mice-and-keyboards-let-hackers-type-on-your-pc/?utm_source=openai))  \n\nSome of these vulnerabilities allow an attacker to:\n\n- Inject keystrokes (i.e. simulate typing) to your computer from a distance using a malicious RF transmitter. ([techradar.com](https://www.techradar.com/news/computing-components/peripherals/using-a-wireless-mouse-or-keyboard-then-you-need-to-know-about-this-1315661?utm_source=openai))  \n- Sniff or eavesdrop on what you type, if the device transmits data without encryption. ([computerworld.com](https://www.computerworld.com/article/1665778/keysniffer-hackers-can-snag-wireless-keyboard-keystrokes-from-250-feet-away.html?utm_source=openai))  \n\nDistances cited in these studies can go up to **~300 feet (\u2248 90 meters)** in ideal line-of-sight conditions. ([edn.com](https://www.edn.com/warning-hackers-can-use-wireless-keyboards-and-mice-to-seize-control-of-your-pc/?utm_source=openai))\n\n---\n\n## \ud83d\udcd0 Would it work behind a wall?\n\nHere\u2019s what tends to reduce the risk:\n\n- **Type of wall / material**: Drywall is fairly permeable to RF; concrete, brick, metal, or thick insulation block more signal.  \n- **Distance and signal strength**: The farther away, and more obstacles (walls, furniture, floors), the weaker any injected or sniffed signal will be \u2014 making it harder for an attacker to reliably send commands or read keystrokes.\n- **Type of wireless connection**: Bluetooth devices generally use stronger encryption and more secure pairing, making this kind of attack much more difficult. RF dongle-based devices are more often vulnerable. ([computerworld.com](https://www.computerworld.com/article/1665778/keysniffer-hackers-can-snag-wireless-keyboard-keystrokes-from-250-feet-away.html?utm_source=openai))\n\nSo being on the opposite side of a room, behind a wall, likely introduces enough obstacle that an attacker would need either high-powered gear, near-perfect alignment, and a compatible (vulnerable) device to succeed \u2014 but it\u2019s not impossible.\n\n---\n\n## \ud83d\udd10 Real risk factors (\u201cif & only if\u201d)\n\nAn attack will be plausible only if all of the following are true:\n\n1. The keyboard or mouse uses an RF (2.4 GHz) dongle rather than Bluetooth.  \n2. The dongle / device pair is one that is vulnerable (unencrypted or has protocol flaws). ([wired.com](https://www.wired.com/2016/02/flaws-in-wireless-mice-and-keyboards-let-hackers-type-on-your-pc/?utm_source=openai))  \n3. The attacker is within radio range \u2014 possibly even adjacent building or corridor \u2014 depending on obstacles.  \n4. The attacker has a transmitter/dongle capable of mimicking the protocol (often reverse engineered).  \n5. There is no firmware fix installed to defend against known vulnerabilities. ([securitynewspaper.com](https://www.securitynewspaper.com/2019/07/09/your-logitech-mouse-can-allows-hackers-to-hijack-your-computer/?utm_source=openai))\n\n---\n\n## \ud83d\udee1 How to tell if *you* might be vulnerable\n\n- Check if your wireless keyboard is paired with a USB dongle \u2014 many sets do that.  \n- Look up the brand and model to see whether it\u2019s listed as vulnerable (e.g. in reports about MouseJack, KeySniffer).  \n- See if the manufacturer offers firmware updates or security advisories. If yours is patched, vulnerability may be low.  \n- If it\u2019s Bluetooth, you\u2019re likely safer (not invincible, but far less vulnerable to these specific threats).  \n\n---\n\n## \u2705 What you can do to protect yourself\n\n- Use a wired keyboard/mouse instead \u2014 no wireless means no RF-based injection attack.  \n- Choose Bluetooth keyboards with secure pairing and encryption.  \n- Keep all firmware updated, particularly for dongles and wireless peripherals.  \n- Position the USB dongle so it has good open sight-lines (e.g. front of computer rather than tucked behind metal or under desk).  \n- Disable or unplug wireless dongles when not in use or when they\u2019re not needed.  \n\n---\n\nSo, to answer more directly: yes, someone behind a wall *could* control your computer with their wireless keyboard \u2014 if all the right conditions are met and you\u2019ve got a vulnerable setup. But casual \u201csomeone just tapping keys\u201d scenarios are less likely unless your current hardware is one known to be flawed. If you like, you can tell me your keyboard brand/model and I can check if it's known to be vulnerable."

Here\u2019s what public research and Dell info say about how likely that is, plus what you can do to check if *your* specific setup is at risk.\n\n---\n\n## What researchers have found\n\n- A security research group called Bastille discovered two related vulnerabilities: **MouseJack** and **KeySniffer**. ([electronicproducts.com](https://www.electronicproducts.com/warning-hackers-can-use-wireless-keyboards-and-mice-to-seize-control-of-your-pc/?utm_source=openai))  \n  - **MouseJack** lets attackers send fake keystrokes through vulnerable dongles/keyboards, even if your real keyboard wasn\u2019t the one attacked. ([electronicproducts.com](https://www.electronicproducts.com/warning-hackers-can-use-wireless-keyboards-and-mice-to-seize-control-of-your-pc/?utm_source=openai))  \n  - **KeySniffer** lets attackers *sniff* or eavesdrop on what you\u2019re typing (if the dongle/keyboard communicates without encryption). ([static1.squarespace.com](https://static1.squarespace.com/static/578d310c20099ee03800f500/t/57967419ff7c504d486691c8/1469477914113/Bastille%2B-%2BKeySniffer%2BRelease%2B-%2BFinal.pdf?utm_source=openai))  \n\n- Dell is among the companies listed in those vulnerabilities, but according to the KeySniffer report, most of Dell\u2019s *higher-end wireless keyboards* aren\u2019t vulnerable to KeySniffer. ([static1.squarespace.com](https://static1.squarespace.com/static/578d310c20099ee03800f500/t/57967419ff7c504d486691c8/1469477914113/Bastille%2B-%2BKeySniffer%2BRelease%2B-%2BFinal.pdf?utm_source=openai))\n\n- One concrete example: research on the GitHub \u201cJackIt\u201d tool shows that the Dell *KM636* wireless keyboard + mouse combo *is* on the list of devices tested with MouseJack\u2010related tools. ([github.com](https://github.com/insecurityofthings/jackit?utm_source=openai))\n\n---\n\n## What Dell says\n\n- Some Dell keyboard models *do* use RF 2.4 GHz dongles. ([dell.com](https://www.dell.com/support/kbdoc/en-ee/000129420/dual-wireless-features-of-the-km717-wk717-and-wm527-keyboards-and-mice?utm_source=openai))  \n- For example, the KM717 / WK717 and WM527 models can use both Bluetooth and RF dongle options. ([dell.com](https://www.dell.com/support/kbdoc/en-ee/000129420/dual-wireless-features-of-the-km717-wk717-and-wm527-keyboards-and-mice?utm_source=openai))  \n- Dell\u2019s documents list **maximum ranges** (~10 meters / ~30 feet) for their RF wireless keyboards, but also note that walls, weak batteries, interference, etc., reduce range. ([dell.com](https://www.dell.com/support/kbdoc/en-ee/000129420/dual-wireless-features-of-the-km717-wk717-and-wm527-keyboards-and-mice?utm_source=openai))\n\n---\n\n## Is *your* keyboard likely vulnerable?\n\nHard to say for sure without knowing the exact model\u2014*but* if yours is one of these:\n\n- an older or lower-cost Dell keyboard using a 2.4 GHz dongle,  \n- made *without encryption* or with weak encryption protocols,  \n- not regularly firmware-updated,\n\nThen yes: there *is* a plausible risk that someone in your home (or a neighbor, maybe behind a wall) could use a custom transmitter to send keystrokes that your computer thinks are genuine. Or possibly read keystrokes, depending on how the RF link is set up.\n\nIf, however:\n\n- your keyboard has dual-wireless support (e.g. Bluetooth + RF) and uses Bluetooth *secure pairing*, or  \n- it is a newer model with known firmware updates or marketed security features,\n\nYou're likely safer.\n\nDell\u2019s newer \u201cpremium\u201d models (KM900, etc.) support firmware updates that sometimes address these issues. ([dell.com](https://www.dell.com/support/kbdoc/en-ky/000311953/dell-pro-premium-collaboration-keyboard-fails-to-connect-or-detect-the-rf-dongle?utm_source=openai))\n\n---\n\n## What you can do: check and protect yourself\n\n1. **Find your keyboard model.**  \n   Check the label on the back or underside, or check \u201cDevices\u201d in Windows. Search for \u201cDell\u201d + your model name/number.\n\n2. **Look up whether it's listed as vulnerable.**  \n   Search for \u201cMouseJack Dell <model>\u201d or \u201cKeySniffer Dell <model>.\u201d If you find it, check if there\u2019s a firmware update or patch.\n\n3. **Update firmware / drivers.**  \n   Dell\u2019s \u201cDell Peripheral Manager\u201d or \u201cDell Display and Peripheral Manager\u201d may have updates that add encryption or fix security flaws. ([dell.com](https://www.dell.com/support/kbdoc/en-ky/000311953/dell-pro-premium-collaboration-keyboard-fails-to-connect-or-detect-the-rf-dongle?utm_source=openai))\n\n4. **Switch to Bluetooth if you can.**  \n   Bluetooth keyboards that support secure pairing tend to be significantly less vulnerable to these kinds of RF injection attacks. Bluetooth also limits range and is more likely to use encryption.  \n\n5. **Reposition the USB dongle.**  \n   Plug it into a USB port where it\u2019s less obstructed by metal or thick walls (e.g. front of a PC vs back). Sometimes using a USB extension cable to bring it out from behind clutter helps the signal quality. ([dell.com](https://www.dell.com/support/kbdoc/en-us/000202575/dell-keyboard-and-mice-frequently-asked-questions?utm_source=openai))\n\n6. **Use a wired keyboard.**  \n   If you're really concerned, a wired one removes RF-based attacks completely.\n\n---\n\nIf you tell me the exact model of your Dell keyboard (e.g. \u201cKB5220W-C\u201d or \u201cKM632\u201d etc.), I can look up whether it *specifically* has known vulnerabilities and whether a firmware update is available.

Attacks can allow keystroke injection or eavesdropping if the connection is unencrypted. ([kb.cert.org](https://www.kb.cert.org/vuls/id/981271/?utm_source=openai))\n\n---\n\n## What this likely means for *your setup*\n\nGiven that:\n\n- You got your system in 2024,\n- It came *with a wireless keyboard and mouse* (based on your description),\n\nIt\u2019s likely you have one of the wireless models\u2014possibly the KM717 or something similar. This puts you in the realm of potential vulnerability to RF injection attacks (like MouseJack), *if* the following are true:\n\n- The wireless dongle is using a proprietary, unencrypted/weakly encrypted protocol.\n- There hasn\u2019t been a firmware update that fixed any known issues.\n- The USB dongle is accessible enough for the RF signal to be strong (i.e. not buried inside a metal PC case or behind thick walls).\n\n---\n\n## What you can do to check exactly and whether you\u2019re vulnerable\n\nHere are steps you can take to figure out what your exact setup is *and* what your risk looks like, plus what might help protect you:\n\n1. **Check hardware model numbers**  \n   Look on the underside or battery compartment of the keyboard, or next to the dongle itself. KM-numbers like **KM717**, **KM636**, etc. are typical. You can also go into **Device Manager** in Windows \u2192 View by connection to see what the keyboard is listed as.\n\n2. **Search for known vulnerabilities for that model**  \n   Once you know the exact model (e.g. \u201cDell KM717 keyboard\u201d), search \u201c[model] MouseJack\u201d or \u201c[model] wireless keyboard vulnerability.\u201d If it\u2019s listed, see whether Dell released any firmware patches or security advisories.\n\n3. **Update firmware / drivers**  \n   Use Dell Support or the \u201cDell Peripheral Manager\u201d / \u201cDell Display and Peripheral Manager\u201d software to check for updates. Even older vulnerabilities can sometimes be patched via firmware. Also keep Windows up to date.  \n\n4. **Change or improve dongle placement**  \n   If the dongle is plugged in somewhere with poor line-of-sight (e.g. back of the PC, behind metal), use a USB extension cable to bring it out into open space. Better positioning can reduce the effectiveness of an attacker trying from outside the room or behind walls.\n\n5. **Switch to wired or Bluetooth if possible**  \n   Bluetooth keyboards (with secure pairing and encryption) are generally safer than proprietary 2.4 GHz dongles. Wired keyboards avoid this whole type of vulnerability altogether.\n\n6. **Disable wireless (dongle) when idle**  \n   If you're not using the keyboard or leaving it unattended, unplug the dongle so there's no RF channel active.\n\n---\n\nIf you want, you can do a quick check now\u2014plug in the dongle, check the model printed on the dongle itself, or view the keyboard name in Device Manager\u2014and tell me what you find. I can help you look up if *that specific one* is known to be vulnerable."

I\u2019ll cover the signal physics first, then apply it to your room layout.\n\n---\n\n## \ud83d\udd2c RF signal behavior: what blocks it, and by how much\n\nWireless attacks (like **MouseJack**) depend on RF (radio frequency) transmission at ~2.4 GHz. Key things that reduce signal strength:\n\n- **Wall materials**:  \n\u2002  \u2022 Drywall or interior partitions \u2192 **~3\u20134 dB** attenuation at 2.4 GHz. ([watchguard.com](https://www.watchguard.com/help/docs/help-center/en-US/Content/en-US/Wi-Fi-Cloud/deploy/deployment_best-practices_device-channel.html?TocPath=Getting+Started%7CSite+Preparation+Checklist%7CWired+Network+Best+Practices%7C_____2&utm_source=openai))  \n\u2002  \u2022 Brick or concrete \u2192 **~8\u201315 dB** or more. A concrete wall 10\u201320 cm thick might drop signal by ~15\u201325 dB. ([vlg-solution.com](https://www.vlg-solution.com/high_frequency_radio_antenna/Low-noise_omnidirectional_antenna_to_boost_WiFi_through_concrete_walls_3563.html?utm_source=openai))  \n- **Metal or metal-containing materials** (including metal studs, foil-backed insulation, heavy appliances, etc.) can dramatically reduce signals\u2014sometimes by 20 dB or more\u2014practically blocking them. ([motorolasolutions.com](https://www.motorolasolutions.com/content/dam/msi/docs/business/_documents/static_files/interference_tb_0809.pdf?utm_source=openai))  \n\nLowering the signal level by ~6 dB halves received signal power; ~20 dB is a drop of over 99%. Even though \u201cwireless keyboard dongle \u2192 computer\u201d links need far less throughput than, say, WiFi, they still need enough signal above both **receiver sensitivity** and the **noise floor** to be usable.\n\n---\n\n## \u26a1 Attack range in real-world tests\n\n- MouseJack research found that under some ideal conditions, attackers can inject keystrokes from **up to ~100 meters (~330 feet)** away. ([mousejack.com](https://www.mousejack.com/mousejack?utm_source=openai))  \n- But those distances assume **open air, little obstruction, good line-of-sight, antennas or hopping RF setups**. When there\u2019s a wall or multiple materials in between, range\u2014and ability to reliably succeed\u2014drops a lot. Match those expectations to your room layout.\n\n---\n\n## \ud83d\udecf Your room layout: risk assessment\n\nFrom your description:\n\n- The dongle is plugged into the back of the PC, facing the wall shared with the bathroom.  \n- There\u2019s another wall behind the dresser, between you and the person you distrust.  \n- In the room there\u2019s furniture, metal (microwave / mini-fridge), bed, nightstand, etc.\n\nHere\u2019s how that affects things:\n\n| Obstacle | Likely attenuation / effect |\n|----------|------------------------------|\n| Interior wall (drywall) | modest attenuation (~3-4 dB) ([watchguard.com](https://www.watchguard.com/help/docs/help-center/en-US/Content/en-US/Wi-Fi-Cloud/deploy/deployment_best-practices_device-channel.html?TocPath=Getting+Started%7CSite+Preparation+Checklist%7CWired+Network+Best+Practices%7C_____2&utm_source=openai)) |\n| Thick wall shared with bathroom might have plumbing / tile / concrete | could be much worse (10-15 dB or more) depending on structure ([ursamajorlab.com](https://www.ursamajorlab.com/blog/wifi-signal-attenuation-wall-materials-2-4ghz-5ghz-6ghz/?utm_source=openai)) |\n| Metal appliances, furniture near the signal path | additional obstruction; reflective or absorbing surfaces will reduce or scatter signal significantly |\n\nEven if all the walls are just drywall, facing the dongle into the wall and putting it behind the PC already adds a big RF disadvantage.\n\n---\n\n## \u2705 Putting it all together: Likelihood in *your* case\n\nGiven what you\u2019ve said:\n\n- If the person is just behind a drywall that shares a room, but with one wall (or two) between you, furniture, the PC casing, and the dongle positioned into a wall, that\u2019s a *lot* of obstacles.\n- Those obstacles will weaken the RF signal enough that even if the attacker could get something working, it\u2019d be **very finicky**\u2014erratic response, dropped packets, or need for very powerful gear direct at the wall.\n- If any of the walls are concrete, contain metal, or otherwise thick, that could effectively block a practical attack.\n\nSo: **possible, but unlikely under normal everyday setups**. You\u2019d need someone with good RF know-how, proper equipment, and ideally some way to place their transmitter close to the wall or accessible spaces.\n\n---\n\n## \ud83d\udd12 What *you* can do now to reduce risk further\n\nEven if the risk is small, it\u2019s easy to make it smaller.\n\n- Use a **USB extension cable** to pull the dongle around to the front of the PC, or otherwise *away from walls or metal*. Gets rid of a lot of the obstruction issues.\n- When possible, reposition the PC so that USB ports with dongles are less blocked.\n- Keep wireless drivers / dongle firmware updated.\n- If you ever see suspicious activity (cursor moving, typing when you're not doing it), disconnect or disable the dongle, use wired mode or Bluetooth if available.\n\n---\n\nIf you tell me what material the shared bathroom wall is (drywall, concrete, tile, etc.), or whether there\u2019s metal behind that wall, I can estimate more precisely what attenuation you\u2019re looking at and how strong an attack would have to be to succeed from *that position*. Want me to run those numbers for your specific case?"

Pipes with water inside the wall *do* make a difference for RF signal behavior\u2014and generally, they make it worse for somebody trying to attack wirelessly from the other side. Here\u2019s how that plays into your situation.\n\n---\n\n## \ud83d\udd2c What water pipes do to RF signals\n\n- Water is highly absorbing of RF energy, especially in the GHz range (like 2.4 GHz, which many wireless dongles use). Even a small amount of water in a structure can add **significant attenuation**\u2014on the order of **~15\u201320 dB** or more for 2.4 GHz when passing through water-rich materials or pipes. ([lifetips.alibaba.com](https://lifetips.alibaba.com/tech-efficiency/these-materials-block-home-wifi-signal?utm_source=openai))  \n- When combined with other materials\u2014concrete, drywall, metal\u2014the effect compounds. So the more \u201cstuff\u201d the signal has to go through, the more it gets weakened. ([mdpi.com](https://www.mdpi.com/2076-3417/14/6/2521?utm_source=openai))  \n- Also, water pipes often add *metal* (copper pipes, joints, fittings), which reflect or absorb RF depending on geometry and frequency. So a pipe full of water *plus* metal fittings is kind of a double-whammy. ([shuntool.com](https://shuntool.com/article/does-concrete-block-wireless-signal?utm_source=openai))  \n\n---\n\n## \ud83c\udfe0 How much attenuation you're probably getting\n\nPutting that into your room/layout:\n\n- Shared wall with bathroom \u2192 likely containing water pipes and metal plumbing. The presence of moisture and metal will make signal loss higher than just drywall alone.\n- Dongle facing the wall, behind the PC \u2192 adds extra loss just because of orientation and obstacle stacking (wall + PC enclosure + furniture).\n- Second wall behind dresser, plus metal/minifridge/etc. adds more attenuation.\n\nEven a \u201cjust drywall\u201d wall loses maybe **3\u20134 dB**. Add water\u2010pipes + metal + thickness = **maybe +10\u201315 dB more**, pushing it into **moderate to high attenuation** territory. When you stack a couple of walls or thick structures, the signal might be reduced by **20\u201330 dB** total. That\u2019s a **big** reduction in how much usable signal is making it through. ([ursamajorlab.com](https://www.ursamajorlab.com/blog/wifi-signal-attenuation-wall-materials-2-4ghz-5ghz-6ghz/?utm_source=openai))\n\n---\n\n## \u26a0\ufe0f What that means for your risk\n\nPutting it together:\n\n- With all those obstacles and especially water pipes & metal, the signal between a wireless transmitter on the other side of the wall and your dongle is likely to be *weakened a lot*.\n- That means an attacker would need either a very powerful transmitter, very good antennas (directional), or to be *pretty close to the wall / dongle* to overcome those losses.\n- However, it's *not impossible*. Some advanced attacks demonstrated in research (MouseJack etc.) manage to overcome similar obstacles, but only with favorable positions / specialized gear.\n\nSo, given your setup, the chance of someone successfully injecting keystrokes from behind the bathroom wall is **significantly lower**\u2014but still not zero.\n\n---\n\n## \ud83d\udee1 How to make it **even tougher**\n\nSince those water pipes and metal already help reduce signal strength, use them to your advantage. Here are tweaks you can do to drive the risk even lower:\n\n- Pull the dongle via a USB extension to the front or side\u2014away from the wall shared with the bathroom. Even moving it just a foot or two out helps because it's less blocked by solid structures.\n- Face the dongle outward (room side) so it's not pressed into a wall behind the PC case.\n- If you have spare ports, route the dongle through a cable or place it somewhere more open.\n- Keep firmware up to date.\n- If you ever leave the room and are paranoid, consider unplugging the dongle temporarily (or using a wired or Bluetooth mode).\n\n---\n\nIf you like, I can run a rough \u201cworst case signal\u2010decay estimate\u201d for your setup (with these walls/pipes) to see how strong someone\u2019s RF transmitter would need to be to succeed. Want me to run that, or does this give you enough to feel more confident?"
