AI-designed universal coronavirus vaccine passes first human trial

Scientists have successfully tested an AI-designed universal coronavirus vaccine in humans for the first time, finding it to be safe and well tolerated. The vaccine generated immune responses against multiple coronaviruses, including SARS-CoV-2, SARS, and related bat viruses with pandemic potential. By targeting features shared across an entire virus family, it aims to provide protection even as viruses evolve.

Scientists discover a hidden quantum world inside cobalt

Scientists have uncovered unexpected quantum complexity inside cobalt, a metal long thought to be fully understood. Advanced measurements revealed a dense network of topological electronic states that remain robust at room temperature. These states enable extremely fast electron behavior and can be switched or controlled using magnetism. The discovery could open new paths toward next-generation computing and spin-based devices.

Attackers obtained encrypted password vaults from some Dashlane user accounts

Dashlane has disclosed new details about a brute-force attack that let a threat actor access some customer accounts and copy encrypted vaults. Dashlane said it found no evidence that the attackers compromised its internal systems. The company first acknowledged the incident on May 31 after users reported receiving account suspension emails and experiencing login problems. “Your account has been temporarily suspended for security reasons as someone has attempted to register a new device and didn’t … More → The post Attackers obtained encrypted password vaults from some Dashlane user accounts appeared first on Help Net Security.

Let’s Encrypt works toward post-quantum certificates at web scale

Let’s Encrypt plans to pursue a post-quantum-safe Web PKI through Merkle Tree Certificates (MTCs), a new approach that adds post-quantum authentication to the web without sacrificing the speed and reliability that have made TLS universal. The project is targeting late 2026 for a staging environment that issues MTCs, with a production-ready environment planned for 2027. “For much of the last several years, the conversation about post-quantum cryptography has been a conversation about encryption. The reasoning … More → The post Let’s Encrypt works toward post-quantum certificates at web scale appeared first on Help Net Security.

Cisco SD-WAN 0-day exploited, no patch available (CVE-2026-20245)

A 0-day privilege escalation vulnerability (CVE-2026-20245) in Cisco Catalyst SD-WAN Manager that has yet to be patched by Cisco is being leveraged by attackers. “To exploit this vulnerability, an attacker must have netadmin privileges on an affected system. This would require valid credentials or exploitation of CVE-2026-20182 or CVE-2026-20127. Cisco is not aware of successful exploitation by other methods,” the company shared on Thursday. It also said that it has observed “limited cases where the … More → The post Cisco SD-WAN 0-day exploited, no patch available (CVE-2026-20245) appeared first on Help Net Security.

AI is helping low-skill hackers pull off advanced cyberattacks

Anthropic has published an analysis of cyber-related misuse of its AI systems, examining 832 accounts that were banned for malicious cyber activity between March 2025 and March 2026. The company mapped the observed behavior to the MITRE ATT&CK framework, which documents tactics and techniques used by attackers. “These 832 cases are just a subset of the total number of accounts banned during this period, but they represent those where we had enough detail to conduct … More → The post AI is helping low-skill hackers pull off advanced cyberattacks appeared first on Help Net Security.
