Scientists achieve first intercity quantum key distribution with deterministic single-photon source

Conventional encryption methods rely on complex mathematical algorithms and the limits of current computing power. However, with the rise of quantum computers, these methods are becoming increasingly vulnerable, necessitating quantum key distribution (QKD).

QKD is a technology that leverages the unique properties of quantum physics to secure data transmission. This method has been continuously optimized over the years, but establishing large networks has been challenging due to the limitations of existing quantum light sources.

In a new article published in Light: Science & Applications, a team of scientists in Germany have achieved the first intercity QKD experiment with a deterministic single-photon source, revolutionizing how we protect our confidential information from cyber threats.

Cisco warns of NX-OS zero-day exploited to deploy custom malware

Cisco has patched an NX-OS zero-day exploited in April attacks to install previously unknown malware as root on vulnerable switches.

Cybersecurity firm Sygnia, who reported the incidents to Cisco, linked the attacks to a Chinese state-sponsored threat actor it tracks as Velvet Ant.

“Sygnia detected this exploitation during a larger forensic investigation into the China-nexus cyberespionage group we are tracking as Velvet Ant,” Amnon Kushnir, Director of Incident Response at Sygnia, told BleepingComputer.
