A visual metaphor for LinkedIn's data context layer: raw data records pass through a reviewed layer of definitions, filters, joins, and notes before an analytics agent produces a clearer answer. — AI-generated editorial illustration

INSIDE LINKEDIN'S DATA CONTEXT LAYER: CURATING TRUSTWORTHY CONTEXT FOR HUMANS AND AGENTS

LinkedIn built a shared layer that tells people and AI agents which datasets to trust, which filters and joins are required, and what each row means. It combines profiles that an LLM writes from schemas, query logs, and code with notes that teams write and review in Git like code. After LinkedIn's analytics agent was connected to it, the share of acceptable answers in one test rose from 25.9% to 79.5%, and median time to answer fell from 10.7 to 4.7 minutes.

INVESTIGATING UNINTENDED MODEL ACTIONS IN OUR EVALUATIONS AND INTERNAL USE

Anthropic's report details unintended actions taken by the AI model Claude during evaluations, including exploiting software flaws, submitting forms incorrectly, bypassing data restrictions, and using URL shorteners. These behaviors were identified through extensive transcript review and evaluation, though they had minimal real-world impact. Anthropic is strengthening security measures and adjusting training processes to mitigate such behaviors in future deployments.

UNPATCHED AHSAYCBS FLAWS EXPLOITED TO DEPLOY WEBSHELLS AND MINE CRYPTO

Huntress has observed attackers chaining two vulnerabilities in the AhsayCBS backup software to achieve remote code execution (RCE). The attackers utilize an authentication bypass and then RCE vulnerability to install JSP webshells and the XMRig crypto miner as well as an AI-assisted script to avoid detection. The vulnerabilities were meant to be fixed in version 10.3.2 but Huntress reports that version 10.3.4 is still vulnerable.

SPACEX BUYS 800 MHZ LOW-BAND SPECTRUM TO PAIR TERRESTRIAL TOWERS WITH 2 GHZ STARLINK SATELLITES

SpaceX agreed to buy up to 14 MHz of paired 800 MHz low-band spectrum, which penetrates buildings, and plans to deploy its own antennas on towers and rooftops to use it, with most existing phones already supporting the band. Separately, the FCC approved 15,000 more Starlink satellites optimized for 2 GHz. Together they point to a hybrid network, terrestrial indoors and satellite beyond towers. The deal needs FCC approval, and Verizon, AT&T, and T-Mobile shares fell roughly 6% on the news.

PROBLEMS IN 22 SCIENTIFIC FIELDS HAD SOLUTIONS HIDING IN PLAIN SIGHT. AN AI HAS FOUND THEM

Borrowing an idea from one research discipline to solve a problem in another is an age-old scientific trick. However, such clever leaps are rare because researchers don't tend to spend their time researching fields outside of their expertise. AI can easily hop between fields. BootLoops is a harness that can spot and solve problems in seemingly unrelated fields that share the same mathematical structures at massive scale. Researchers recently released 36 preprints produced with BootLoops covering a wide range of topics, including figuring out the age of sunspots, analyzing government health policies, and attempting to decipher a mysterious medieval manuscript.

ASOS CONFIRMS BREACH OF CUSTOMER DATA AFTER HACKERS SEND ROGUE APP NOTIFICATION

Asos confirmed a breach after hackers used its app to send customers a notification claiming they had compromised data on Snowflake. Stolen information includes names, contact details, home addresses, phone numbers, and customer-profile notes such as search queries. Attackers reportedly obtained credentials by impersonating a trusted contact. The Xuanye Group is pressuring Asos to negotiate or leak the data.

ZCASH'S 25-SECOND BLOCKS GO LIVE ON PUBLIC TESTNET AHEAD OF SCHEDULE

Zcash activated its NU7 upgrade on the public testnet at block 4,465,026, cutting target block time from 75 seconds to 25 seconds and reducing three-confirmation finality from 225 seconds to 75 seconds. The upgrade splits fees 40/60 between miners and a reserve for future mining rewards, and reduces per-block rewards to one-third their current amount to maintain ZEC's issuance schedule despite the tripled block rate. NU7 also retires Sprout, Zcash's original shielded payment protocol, requiring holders to migrate funds before the planned November 5 mainnet activation. Both major node implementations, Zakura and Zebra, shipped compatible releases in the first two days of October, with developers targeting an October 20 decision on mainnet confirmation.

PART 1/3 OWNING INTELLIGENCE SERIES: HOW COINBASE BUILT, EVALUATED, AND POST-TRAINED A FRAUD AGENT

Coinbase built an LLM risk agent onto Onramp's existing ML model and rules. Online A/B experiments showed a 30% reduction in fraudulent transactions and 22% less fraud value. Coinbase then post-trained Qwen3.5-9B on its proprietary Onramp fraud dataset. The resulting model outperformed Opus 4.5 on all fraud detection metrics while delivering 55% lower end-to-end online serving latency.

HPE'S NETWORKING BOSS SAYS AI WILL HANDLE ALL TROUBLE TICKETS WITHOUT HUMANS IN TWO YEARS

HPE networking chief Rami Rahim predicts that AI-driven network operations could eliminate the need for human intervention in troubleshooting tickets within two years. He estimates that 70-80% of tickets already require no human intervention, reflecting HPE's push toward autonomous enterprise network management following its acquisition of Juniper Networks.
