Researchers have identified Skeleton 150, believed to be the first confirmed victim of a trebuchet, unearthed during excavations beneath Stirling Castle in Scotland in 1997. This skeleton is part of a collection dating back to the 1300s and shows signs of violent death, including distinct cut marks, puncture wounds, and blunt force trauma. Dr. Buckberry from Historic Environment Scotland presented findings indicating that the unusual burial location beneath the castle chapel suggests these individuals may have died during sieges in the late 13th century. Stirling Castle was a strategic stronghold that fell to Edward I's armies after a siege in 1304, during which the largest trebuchet, "The War Wolf," was used. Dr. Buckberry noted that the extensive damage to Skeleton 150 indicates the individual was likely killed by a siege engine.

Security researchers found that several Samsung Smart TV applications, including Pac-Man, were embedding residential proxy SDKs from data brokers like Bright Data. In response, Samsung has banned the inclusion of residential proxy functionality in new app submissions and is working to remove existing apps with such software. The investigation by Norwegian cybersecurity firm Mnemonic revealed that the Bright Data SDK was integrated into various gaming applications, some promoted by Samsung. While Samsung TVs were not automatically sharing internet connections, the SDK could be activated remotely by developers, requiring user consent. Once consent was granted, the proxy service could operate in the background. Many Samsung TV applications were found to download most of their code from remote servers, complicating verification processes. The issue of residential proxy software is not limited to Samsung, as it has also been identified in various Android apps and devices. Following these findings, LG and Google have also taken measures to address the risks associated with residential proxy networks.

Bitsight's investigation revealed that inexpensive Android TV boxes are being shipped with applications that can change their hardware identity, allowing them to impersonate popular smartphone brands like Samsung and Huawei. This operation, named Fuyao, is linked to Zhejiang Fengwo IoT Technology Co., Ltd., a Chinese company established in 2019. The H96MAXV11 model was frequently reported among the affected devices. In one day, the operation received 65,957 reports from about 38,000 unique MAC addresses, with many devices misidentified as phones due to spoofed identifiers. Fengwo has also promoted over 120,000 "AI digital humans," though details on this marketing term are vague. The command-and-control server for Fuyao sends phone profiles to devices, masking their actual hardware specifications. The operation uses machine vision technology and a YOLOv8s object-detection model to identify advertisements. Bitsight documented 40 fraud tasks, 21 unique campaigns, and 166 modules across four devices. The operation's payout structure involves 144 operator-owned domains, with an estimated gross return of .25 per device daily, potentially leading to annual revenues in the millions. Attribution to Fengwo is supported by shared TLS certificate data and public patent records, although the patents do not directly address advertising. There is uncertainty about how the fraudulent apps were installed and at what point in the supply chain they were introduced. Device owners are advised to verify Play Protect certification and disconnect suspicious devices.

Google has introduced a preview of its columnar engine-accelerated HNSW feature for AlloyDB, enhancing vector search throughput by up to four times for users of the pgvector extension in PostgreSQL. This improvement is aimed at approximate nearest neighbor searches using HNSW across large datasets. AlloyDB utilizes a columnar engine that allows HNSW indexes to reside in memory, improving throughput and recall metrics. In benchmark tests on the GloVe 100 Angular dataset, queries per second increased by approximately 4.2x to 4.9x, with recall improving from about 0.78 to over 0.94 at a throughput of around 350 queries per second. The columnar engine's design bypasses traditional PostgreSQL buffer management bottlenecks, enhancing efficiency during graph traversal. The memory architecture is distinct from basic caching techniques, and the feature requires no changes to application code. Users must enable the columnar engine and index caching flags to utilize this feature. Benchmarks were conducted on an AlloyDB C4A machine with 16 virtual CPUs.
