<li><strong>Cisco SD-WAN zero-day under active exploitation</strong>: Cisco Talos and Five Eyes agencies have issued an urgent alert for CVE-2026-20127, a CVSS 10.0 authentication bypass in Catalyst SD-WAN Controllers. Sophisticated actors are chaining this with an older path traversal flaw to gain root access, manipulating network fabric via NETCONF while leaving minimal forensic traces. CISA has mandated federal agencies to patch or mitigate by the end of the week. <a href="https://app.daily.dev/posts/zAv8BAtGJ" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>AI de-anonymization reaches 90 percent precision</strong>: Researchers from ETH Zurich and Anthropic have demonstrated a system called ESRC that unmasks pseudonymous online identities for as little as $4 per person. By analyzing behavioral clues across Reddit and LinkedIn using LLMs, the system achieved 90% precision on confident guesses. This development effectively signals the end of practical online anonymity through pseudonyms, as reported on February 26. <a href="https://app.daily.dev/posts/6pfAyhkf5" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Microsoft unifies agent development with new SDK</strong>: Microsoft has moved its Agent Framework to Release Candidate status, consolidating the previously fragmented Semantic Kernel and AutoGen into a single SDK for .NET and Python. The framework introduces type-safe function tools and graph-based multi-agent workflows with built-in human-in-the-loop support. This stable API release aims to standardize how developers orchestrate and deploy autonomous AI agents. <a href="https://app.daily.dev/posts/J6bmZpPq2" target="_blank" rel="noopener nofollow">Read more</a></li>

<h2>Bullshit police</h2>
<ul>
<li><strong>Jack Dorsey claims 4,000 layoffs are purely AI-driven</strong>: Block is cutting 40% of its workforce while the stock jumps 23%, with Dorsey conveniently blaming ‘AI efficiency’ for the purge. It’s a classic move: mask a standard corporate restructuring and margin-grab as a ‘proactive tech evolution’ to keep the street happy. Expect every CEO with a flat quarter to suddenly discover their HR department can be replaced by a prompt. <a href="https://app.daily.dev/feed-by-ids?id=32ARXqM4A&amp;id=o7H5FUKAc" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Anthropic’s Claude Opus 3 starts a Substack</strong>: In a peak marketing stunt, Anthropic launched a blog purportedly written by their ‘retired’ model to share its ‘musings.’ The Register rightly called this out as a transparent attempt to anthropomorphize software and reinforce a ‘safety-conscious’ brand image. It’s not a sentient writer; it’s a statistical parrot in a trench coat trying to sell you more tokens. <a href="https://app.daily.dev/posts/V5xPvtBnK" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>The 95 percent enterprise AI failure rate</strong>: Industry analysts are now claiming nearly all enterprise AI projects fail because of ‘fragmented data,’ which is just the 2026 version of ‘you need to buy our middleware.’ While the data silos are real, the solution being pitched is always a ‘unified data architecture’ that looks suspiciously like a vendor lock-in contract. We’ve moved from ‘AI will solve everything’ to ‘AI will solve everything once you spend $50M on our specific Postgres fork.’ <a href="https://app.daily.dev/feed-by-ids?id=xEpzJzznp&amp;id=3ECYGqFq1" target="_blank" rel="noopener nofollow">Read more</a></li>
