Bit errors have been used to hijack communications. Just register a bunch of domains that differ from popular ones by a single bit and watch the requests come in.[1]
Typically, users don't recognize single bit errors. Something breaks and they think, "Stupid buggy software." With modern RAM capacities, you're pretty likely to get some bits flipped every few months.

With modern RAM capacities, you're pretty likely to get some bits flipped every few months. Supposedly much higher than that[1]. More like "5 single bit errors in 8 Gigabytes of RAM per hour using the top-end error rate" [2] 1. http://www.cs.toronto.edu/~bianca/papers/sigmetrics09.pdf http://www.cs.toronto.edu/~bianca/papers/sigmetrics09.pdf 2. https://en.wikipedia.org/wiki/ECC_memory https://en.wikipedia.org/wiki/ECC_memory
