Spooky Bug Tales: A Halloween special blog on seemingly paranormal tech bugs

In this piece, I have compiled some spooky tech bugs that i came across which would have definitely creeped me out if I encountered them in real life. I have massive respect for the devs and researchers who could think through the noise and crack these cases. Most of these require some next level problem solving and out-of-box thinking.

Case 1 : During a 2013 Super Mario 64 speedrun, Mario suddenly teleported upward through a ceiling. This glitch that had never happened before and couldn't be replicated at all. Cause: After years of testing, the community concluded it was likely caused by a single-event upset (SEU) — a rogue cosmic ray from deep space striking the Nintendo 64 console and flipping a single bit of data in its memory from a 0 to a 1.

Case 2: When the Raspberry Pi 2 was released in 2015, users noticed that taking a flash photograph of the board caused it to instantly reboot. Cause: The culprit was a tiny, exposed power-regulator chip. The high-intensity light from a xenon camera flash generated enough photoelectric current inside the chip to drop the computer's voltage, tricking it into thinking it had lost power.

Case 3 : In 2023, a developer noticed that his computer monitor would randomly turn off for a few seconds whenever he stood up or sat down. Cause : Electrostatic discharge from an IKEA office chair caused this. The fabric and gas lift cylinder of the chair built up a massive static charge whenever the user moved. This charge traveled through the chair's metal frame and radiated an electromagnetic pulse through the air, which was strong enough to temporarily disrupt the unshielded video signal passing through a nearby DisplayPort cable.

Case 4 : In 1995, early PlayStation 1 developers were stumped when a tester reported that a game's save files corrupted every single time the tester used the bathroom. Cause: The tester was using a specific TV and console setup wired into an old building's electrical circuit. Flipping the bathroom light switch caused a tiny, instantaneous drop in voltage across the circuit. If the console happened to be writing data to the memory card at that exact millisecond, the voltage drop corrupted the data.

Case 5 : In the 1980s, Therac-25 was a radiation therapy machine used in hospitals to deliver precise doses of radiation to cancer patients. However, the machine delivered lethal doses of radiation to some patients, causing serious injuries and even deaths. Cause : This was caused by a race condition in the software that controlled the machine's electron beam. It would sometimes switch from low-energy to high-energy mode without the operator's knowledge, leading to overdoses.

Case 6: In 1978, Intel's 16-kilobit DRAM chips corrupted at random in a non-repeatable fashion. These errors left behind zero physical defects and there were no manufacturing defects found. Cause: The chip was producing non-repeatable bit errors which was traced to alpha particles emitted by trace uranium and thorium in the ceramic packaging. The contamination was reportedly traced to the water used in making the ceramic, sourced downstream of an old uranium mine.

Case 7: In 2007, twelve F-22s crossing the International Date Line lost navigation, fuel management and comms at the same moment. Cause: The flight software could not handle the transition across the 180th meridian due to improper date line handling. The aircraft were guided back by tanker aircraft, and Lockheed Martin patched the software within days.

Case 8: Since the 1920s people have reported hearing unfamiliar voices, music and radio broadcasts through audio equipment even when no audio was playing. Cause: Poorly shielded cables or amplifier circuitry can unintentionally act as radio-frequency receivers. Nonlinear electronic components can demodulate nearby AM radio transmissions, turning electromagnetic signals into audible speech.

Case 9: An office printer suddenly began producing pages containing random characters, symbols and seemingly corrupted text, despite nobody sending a print command. Cause: This issue is typically caused by corrupted drivers, network scans, device inference or a stuck print queue rather than a physical malfunction of the printer. When a printer receives data it cannot interpret, it simply prints the raw code as literal text, resulting in pages of endless gibberish.

Case 10: Some computers unexpectedly wake from sleep or appear to power themselves on without anyone touching the keyboard or power button. Cause: Wake-on-LAN packets and scheduled task wake timers can wake the computer and trigger startup. Here, a network packet can effectively act like an invisible power-button press.

Case 11: In 2022, researchers demonstrated that smartphones could register taps and swipes even when nobody was touching their screens. Their experiments worked on nine smartphone models. Cause: Electromagnetic interference injected into the capacitive touchscreen circuitry created false electrical signals that the phone interpreted as actual human touches. The researchers named the attack GhostTouch.

Case 12: In 2018, owners of Amazon Echo devices and Alexa-enabled smart speakers reported that their devices were randomly and unprompted emitting loud, unsettling fits of laughter without any wake word or intentional command. Cause: The short command "Alexa, laugh" was being falsely triggered by ambient speech. Amazon soon disabled that phrase, replaced it with the longer "Alexa, can you laugh?", and made the response less eerie.

If these were left unsolved they would've been strong cases for haunted devices and paranormal activity. Which also makes you think, how many horror movie scares would just be awful bugs in real life !!
