Hackers Use Claude AI Agents to Automate Cyberattacks, Develop 0-Days and Evade Detection

Anthropic reports state-sponsored and criminal actors used Claude AI agents to automate attacks, discover zero-days, and rewrite malware to evade detection.

Anthropic Threat Intelligence's report covering December 2025 to August 2026 details AI-automated campaigns by espionage groups, criminals, and hacktivists. GTG-20006, aligned with Russia-linked Midnight Blizzard, targeted Ukrainian and European government and drone supply chains, used Claude to autonomously rebuild malware when detected, hijacked hotel Wi-Fi DNS to serve ClickFix lures, and stole over 300,000 identity records from a North African government. Operators linked to ShinyHunters decompiled roughly 1.8 million Android packages for hardcoded secrets and pivoted from an XSS flaw in a SaaS vendor into 200+ downstream organizations in about 34 hours, harvesting 2,100+ Azure AD token sets across 40 tenants. The Chinese-linked GTG-10007 ran parallel agent swarms that surfaced more than a dozen candidate zero-day vulnerabilities in a single month.

ASCII smuggling crosses over from AI prompt injection to phishing evasion

Microsoft details high-volume phishing campaign using ASCII smuggling (Unicode tag chars) for filter evasion, peaking at 2.3M messages.

Microsoft researchers observed a high-volume finance-themed phishing campaign using invisible Unicode tag characters (U+E0000–U+E007F), a technique known from AI prompt injection research as ASCII smuggling, to split lure words like 'funding' and evade email filters. Telemetry from Microsoft Defender for Office 365 showed signature hits jump from roughly 21,000 messages on February 8, 2026 to more than 1.3 million on February 9, peaking above 2.3 million on February 11, with elevated weekday activity lasting approximately three months. The discovery emerged from prompt injection protection research, showing AI-era evasion techniques crossing into traditional phishing. Most messages were flagged by layered Defender protections rather than a single Unicode-specific signal.

OpenAI confirmed it is testing a Writing Style feature for ChatGPT that learns a user's voice from writing samples in connected apps. The onboarding flow references Messaging (Slack), Documents (Google Drive and Notion), and Email (Gmail) as example sources. It resembles Anthropic's Styles personalization feature but draws on existing writing inside connected services rather than uploaded samples. The feature is available to a small group of users with no announced general rollout date.

Technical Manual for a Toolkit for Measuring Contextual Individuation in Transformer Language Models

An open methodology toolkit measures whether transformer language models contextualize fixed word forms across domains using bridge forms and layer-wise silhouette analysis.

The manual documents an open toolkit built around 'bridge forms' - identical written words recurring across two or more subject domains with a different sense in each - to test whether transformer language models individuate word occurrences by context beyond the embedding layer. It covers declarative specification of bridge forms, Wikipedia corpus acquisition, occurrence localization, layer-wise representation extraction, domain-pairwise silhouette measurement, and visualization, justifying each choice against failure modes such as sense contamination and subword-tokenization misalignment. It is a methodological and implementation reference and reports no empirical results.

TaichuAI/ZDTaichu5.0-9B — new model trending #30 on Hugging Face

TaichuAI released ZDTaichu5.0-9B, an open multimodal VLM built on Qwen3.5-9B targeting spatial reasoning, embodied AI, and agentic tool use.

TaichuAI released ZDTaichu5.0-9B, a multimodal vision-language model pairing a Qwen3.5-9B language decoder with a C-RADIOv4-H vision encoder, supporting text, single/multiple images, and video with any-resolution input and a 128K-token context. It introduces Entropy-Gated Adaptive Recurrent Reasoning, which allocates extra latent refinement steps to harder tokens. Reported benchmarks include 87.7 on TAU2-Bench, 71.4 on Claw-Eval, 93.7 on IFEval, 48 on ERQA, and 56 on RoboSpatial, leading compared 10B-scale open VLMs on agent and spatial tasks. The weights are available on Hugging Face, GitHub, and ModelScope, where it is trending at #30.

Once popular for attacking AI, ASCII smuggling is embraced by spammers

Spammers adopt ASCII smuggling—invisible Unicode tag characters—to evade email filters, with Microsoft Defender detections spiking to 2.5 million per day.

ASCII smuggling hides text in Unicode tag characters (e.g., U+E0041 for "A") that are invisible to humans but readable by LLMs and text processors. The technique gained attention as a stealthy prompt-injection vector and is now used by spammers to obfuscate keywords from email detectors. Microsoft reported Defender for Office smuggling detections jumped from roughly 21,000 per day to over 1.3 million in early February, reaching 2.5 million within four days, before falling sharply in mid-May.

Claude's new system prompt really doesn't want to reproduce song lyrics

The latest consumer prompt strongly discourages reproducing song lyrics, a behavioral constraint likely tied to copyright considerations. Prompts for Claude Cowork and Claude Code are not included in the published set.

How AI wiped out an entire industry in Nairobi

ChatGPT's rise collapsed Kenya's contract essay-writing industry, which once employed 40,000 people in Nairobi, cutting $40–70-per-paper earnings after 2022.

The New York Times reports that generative AI, primarily ChatGPT, wiped out Kenya's ghostwriting business, which at its peak employed at least 40,000 people in Nairobi writing academic papers for US and UK students. Writers like Teresios Bundi, who produced over 2,500 papers in twelve years, saw prices and orders collapse after ChatGPT's 2022 launch. Related gig work such as transcription, data annotation, and Meta content moderation has also dried up, leaving 'humanizers' who rewrite AI text to evade plagiarism checks. Kenya's government had promoted online gig work since 2016, and roughly 80 percent of the country's jobs are informal.

ASCII smuggling isn't just an AI security risk

Microsoft tracked a phishing campaign peaking at 2.37 million daily messages that hid financial-lure keywords with invisible Unicode tag characters to evade filters.

Microsoft researchers uncovered a large phishing campaign that inserted invisible Unicode tag characters (e.g., U+E0020) inside common financial keywords like 'funding', splitting words so keyword, signature, and regex matches fail. The campaign peaked at more than 2.37 million messages in late February 2026, ran from about 150 finance-themed sender domains on a strict weekday-only schedule, and gradually declined to under 20% of peak weekday volume by late March, with residual spikes through mid-June. The technique repurposes ASCII smuggling, normally used for indirect prompt injection against AI assistants, for traditional email phishing evasion. Microsoft advises defenders to strip or fold invisible Unicode code points before content matching and to watch for bulk weekday spikes from churning finance-themed domains.

Who Should Grade My Work? Student Perspectives on Transparent AI-Assisted Writing Assessment in Higher Education

A Saudi university study finds students value ChatGPT writing feedback but treat human instructors as the final grading authority.

Thirteen male undergraduate computing students at a Saudi public university completed handwritten writing tasks that were scored by ChatGPT using a rubric-based prompt, then reflected after being told the score and feedback were AI-generated. Inductive thematic analysis identified four themes: perceived feedback usefulness, awareness of AI's contextual and pedagogical limitations, conditional trust, and reflection on the instructor's institutional role. Participants accepted GenAI feedback for surface-level revision but consistently positioned human instructors as the authority over grading decisions, distinguishing feedback utility from evaluative authority.

The Verge documents weeks of erroneous AI Content labels on Instagram, including images edited only with Canva's Background Remover or an iPhone Photos app, while some generative images escape tagging. Canva said some of its assistive AI tools were being tagged as generative and claims the issue is fixed, though users still report tagging. Meta scans IPTC and C2PA metadata and uses signals like Google's SynthID, but remains vague about detection criteria; one tester found only Meta AI-created or edited images reliably triggered labels, and an image-poisoned photo was tagged. A similar mislabeling wave hit Instagram in 2024.
