Kyber ransomware first confirmed to use post-quantum cryptography in apparent psychological tactic
Kyber ransomware has been identified as the first confirmed case of using post-quantum cryptography, drawing attention across the security industry, analysts said. Rapid7 said its review of a Windows variant found it protected encryption keys with ML-KEM1024, while files were encrypted with AES-256. Experts said the move appears aimed at psychological pressure and marketing impact rather than operational need. Some variants also made overstated claims about using ML-KEM.

U.S. Pentagon drops OCX GPS ground control programme after 16 years
The U.S. Defense Department has formally halted OCX, a next-generation ground control system for the U.S. military’s GPS satellite network, after years of technical problems and cost and schedule overruns. The programme, awarded in 2010 to Raytheon, now RTX, was initially expected to cost $3.7 billion and finish in 2016, but government spending rose to about $6.27 billion and total completion was estimated near $8 billion. The U.S. Space Force will instead upgrade the existing GPS control system.
