A trio of researchers split between Italy and the UK have recently published a paper about cryptographic insecurities they found in a widely-known smart light bulb. The researchers seem to have chosen their target device, the TP-Link Tapo L530E, on the basis that it is “currently [the] best seller on Amazon Italy,” so we don’t know how other smart bulbs stack up, but their report has plenty to teach us anyway.
