Researchers in the Netherlands uncovered a deliberate backdoor in encryption used in radios for critical infrastructure, police, intelligence, and military, making communications susceptible to eavesdropping. The European Telecommunications Standards Institute (ETSI) recommended adding end-to-end encryption to mitigate the flaw. However, the same researchers found that one implementation of ETSI's endorsed end-to-end encryption also has vulnerabilities, compressing a 128-bit key to 56 bits before encrypting data, making it easier to crack. The users of this encryption implementation and their awareness of the security flaw remain unclear.

MindsEye's sabotage mission is being slammed as dull and pointless

Build A Rocket Boy accuses individuals of sabotaging MindsEye's launch, spending over €1 million on damaging efforts. The studio integrates the controversy into a new in-game mission, Blacklist, to showcase evidence of sabotage to players. However, reports describe the mission as lackluster and failing to deliver a compelling narrative. Critics attribute the launch issues to internal problems, such as management and design decisions, casting doubt on the sabotage claims. The saga continues as MindsEye's post-launch turmoil unfolds.
