A vulnerability in the domain name system (DNS) component of a popular C standard library that is present in a wide range of IoT products may put millions of devices at DNS poisoning attack risk.

A threat actor can use DNS poisoning or DNS spoofing to redirect the victim to a malicious website hosted at an IP address on a server controlled by the attacker instead of the legitimate location.

The library uClibc and its fork from the OpenWRT team, uClibc-ng. Both variants are widely used by major vendors like Netgear, Axis, and Linksys, as well as Linux distributions suitable for embedded applications.

Japanese researcher Makoto Kasu, at Saga University, and a precision diamond jewellery manufacturer have built a 2-inch diamond-coated wafer that can store, they claim, 25 exabytes of data using quantum memory.

Binary data is stored in quantum superpositions using nitrogen vacancies in the diamond material. Currently binary stored is stored as bits, with a value of one or zero, represented by magnetic polarity (north or south), charge in flash (current flows or not) or resistance in ReRAM (high or low). Quantum memory is different in that it stores qubits (quantum bits).

As we understand it, a qubit can have a value of ⎢0⟩ or⎢1⟩ (pronounced “ket 0” and “ket 1”) or a linear combination of both states in any proportion – it does not have a single value. It has a certain probability of being a ⎢0⟩ and another probability of being a ⎢1⟩. This property of a qubit is called superposition and is used in quantum computing, which can use other quantum phenomena such as entanglement and interference.

Though NASA’s aircraft may prove why electric flight isn’t the way to go. NASA is edging nearer to its first flight test for its all-electric experimental “X-plane” X-57 Maxwell after completing ground tests on the aircraft, a blog post from the space agency reveals.
