There is no practical benefit for Kyber developers to have chosen a PQC key-exchange algorithm. The Kyber ransom note gives victims one week to respond. Quantum computers capable of running Shor’s algorithm —the series of mathematical equations that allow the breakage of RSA and ECC (elliptic curve cryptography)—are, at a minimum, three years away and likely much further. A Kyber variant that targets systems running VMware, meanwhile, claims to use ML-KEM as well. Rapid7 said its look under the hood revealed that, in fact, it uses RSA with 4096-bit keys, a strength that will take even longer for Shor’s algorithm to break. Anna Širokova, a Rapid7 senior security researcher and the author of Tuesday’s post, said the use or claimed use of ML-KEM is likely just a branding gimmick and that implementing it required relatively little work by Kyber developers. In an email, Širokova wrote: First, it’s marketing to the victim.…
