AWS KMS Adds Ed25519 (EdDSA) Support for Signatures

🔐 AWS Key Management Service (KMS) now supports the Edwards-curve Digital Signature Algorithm (EdDSA) using the Ed25519 curve. You can create asymmetric KMS keys or data key pairs to sign and verify EdDSA signatures, benefiting from 128-bit security equivalent to NIST P-256, faster signing, and compact 64‑byte signatures and 32‑byte public keys. This capability is available in all AWS Regions, including GovCloud and China.

Cloudflare Removes Aisuru Botnet Domains from Rankings

🛡️ Cloudflare has begun redacting and hiding domains tied to the rapidly growing Aisuru botnet after those malicious hostnames repeatedly appeared atop its public domain rankings. The botnet — comprised of hundreds of thousands of compromised IoT devices — recently shifted from querying 8.8.8.8 to 1.1.1.1, flooding Cloudflare’s resolver and skewing popularity metrics. Cloudflare says attackers are likely both manipulating rankings and mounting attacks on its DNS service, and the company is refining its ranking algorithm while removing known malicious entries.

Rise in Attacks on PHP Servers, IoT and Cloud Gateways

🔒 Qualys' Threat Research Unit reports a sharp rise in attacks targeting PHP servers, IoT devices and cloud gateways, driven by botnets such as Mirai, Gafgyt and Mozi exploiting known CVEs and misconfigurations. Researchers highlight active exploitation of flaws like CVE-2022-47945 (ThinkPHP RCE), CVE-2021-3129 (Laravel Ignition) and aging test/debug artifacts such as CVE-2017-9841, while attackers also harvest exposed AWS credentials. Qualys urges continuous visibility, timely patching, removal of debugging tools in production and managed secret stores to reduce risk.

RondoDox botnet rapidly exploits 56 n-day flaws worldwide

⚠️ RondoDox is a large-scale botnet actively exploiting 56 n-day vulnerabilities across more than 30 device types, including DVRs, NVRs, CCTV systems, routers, and web servers. Trend Micro researchers describe the campaign as using an exploit shotgun strategy, firing numerous exploits simultaneously to maximize infection despite generating noisy activity. The actor has weaponized flaws disclosed at events such as Pwn2Own and continues to expand its arsenal, including both recent CVEs and older end-of-life vulnerabilities. Recommended defenses include applying firmware updates, replacing EoL devices, segmenting networks, and removing default credentials.

Smart Cities Face Growing Cybersecurity Risks and Gaps

🏙️ Smart cities are expanding rapidly—69% of municipalities report strategic agendas and an estimated 83,000 sensors were deployed in 2024—significantly enlarging the attack surface. High-profile incidents (Dallas alarm hack, Washington, DC ransomware, Florida water-treatment manipulation, and Olsztyn transport disruption) show that networked devices can lead to both digital and physical harm. Experts from Accenture, Zebra Technologies, and S2GRUPO warn that legacy devices, fragmented governance, and IT/OT convergence demand zero-trust, segmentation, and coordinated incident response to reduce systemic risk.
