AI Is Already Being Used to Spy, Scam, Hack and Build Weapons. Anthropic’s 154-Page Report Should Make Everyone Uncomfortable
For years, the most frightening conversations about artificial intelligence have focused on what AI might eventually become capable of doing.
What happens when AI can automate sophisticated cyberattacks? Could governments use it to identify and monitor dissidents? Could criminals operate thousands of fake identities at once? Could an AI model assist a weapons program or dangerous biological research?
According to Anthropic’s September 2026 threat intelligence report, we no longer need to treat all of those questions as hypothetical.
The 154-page report, titled Detecting and Countering Misuse of AI: September 2026, documents malicious and prohibited uses of Claude that Anthropic says it detected and disrupted between December 2025 and August 2026.
The cases cover seven broad areas: cyber operations, influence operations, surveillance, scams and fraud, biological misuse, conventional weapons development and illicit AI model distillation.
There is one important caveat.
Anthropic explicitly says these cases do not represent normal Claude usage. They were selected because they were among the most significant and novel threat activities its investigators encountered.
Still, the report reveals something much more important than criminals simply asking chatbots dangerous questions.
AI is increasingly being inserted into the operational machinery of malicious activity.
And that changes what one person, one small group or one government agency can accomplish.
AI Is Moving From Assistant to Operator
Perhaps the most important theme in the entire report appears in the cybersecurity section.
Anthropic describes a transition from AI functioning as an assistant to functioning as an orchestrator.
Traditional cyber operations often require several different kinds of expertise.
Someone performs reconnaissance. Someone develops or modifies malware. Someone manages infrastructure. Someone searches for vulnerabilities. Someone processes stolen data. Someone handles phishing campaigns or compromised accounts.
AI can increasingly perform or coordinate portions of those jobs.
Anthropic describes the impact through something it calls AI uplift, measuring whether AI increases the speed, scale or depth of a threat actor’s operation.
That is an important distinction.
The danger is not simply that an AI suddenly discovers an unprecedented vulnerability and hacks the planet.
A much more realistic threat is that the same attacker can now investigate more targets, understand unfamiliar software faster, write tools faster, process stolen information automatically and continue working around the clock.
Anthropic says this has already made the sophistication of an attack a less reliable indicator of the sophistication of the attacker.
Operations that might once have required teams of specialists can increasingly be performed by much smaller groups using AI agents.
That is a major change in the economics of cybercrime.
A Russian Espionage Operation Shows What AI-Orchestrated Hacking Looks Like
One of the most significant cases in the report concerns a threat actor Anthropic tracks as GTG-20006.
Anthropic says its attribution is consistent with previous public reporting about Midnight Blizzard and describes the activity as consistent with Russian state-linked espionage.
Targets reportedly included Ukrainian and European government organizations, intelligence bodies, diplomatic organizations, defense interests and individuals connected with US foreign policy.
But the most interesting part is how deeply AI was integrated into the operation.
According to Anthropic, AI-assisted workflows were involved in infrastructure development, phishing, persistence, command-and-control activity, data processing and exfiltration.
The attackers also created workflows capable of checking whether malware had been detected by security products.
If detection occurred, AI agents could modify and rebuild parts of the toolkit and continue iterating until the malware was no longer detected.
That creates a difficult problem for defenders.
Traditionally, identifying malware and developing a signature against it imposes a cost on the attacker. The attacker must modify the malware and redeploy it.
Automation potentially compresses that cycle dramatically.
The defender detects.
The AI modifies.
The attacker deploys again.
The game continues.
Welcome to the Era of “Vibe Hacking”
The report also discusses financially motivated operators Anthropic associates with the ShinyHunters ecosystem.
Some of the scale involved is extraordinary.
One operator allegedly created a system that downloaded around 1.8 million Android APK files and automatically searched them for exposed secrets and credentials.
Anthropic describes other compromises involving enterprise cloud systems, SaaS providers and massive amounts of stolen customer data.
In one operation, AI agents reportedly performed nearly all of the work involved in dumping more than 2,100 Azure AD token sets spanning more than 40 corporate tenants in roughly 34 hours.
Anthropic gives some of this activity a surprisingly appropriate name:
“Vibe hacking.”
Instead of manually understanding every system, the attacker gives the AI a broad objective.
Find useful data.
Explore this environment.
Use these credentials.
Gain additional access.
Export whatever is valuable.
The AI then evaluates the environment, writes scripts, executes tasks, summarizes results and continues iterating.
The attacker may not understand every technical detail.
They may not need to.
That resembles the way ordinary developers increasingly use coding agents: describe the outcome and let the system figure out much of the implementation.
Except here, the desired outcome is unauthorized access.
AI Agents Can Hunt for Vulnerabilities While Humans Sleep
Another operation, tracked as GTG-10007, involved Chinese-speaking operators using Claude as an engineering and orchestration layer.
Anthropic says the group maintained separate AI workflows for reconnaissance, malware development, intelligence collection, intrusion attempts and vulnerability research.
Some of those workflows used what the report calls agent swarms.
A lead AI agent divided a larger job between multiple subagents while persistent memory stored information about targets, credentials, instructions and campaign progress between sessions.
The system could effectively resume work rather than starting from scratch every time.
One automated vulnerability-research workflow continuously examined network appliances and reportedly generated more than a dozen possible zero-day findings in a single month.
Again, the most important advantage may not be superhuman intelligence.
It is persistence.
AI does not need sleep.
An automated vulnerability researcher can continue decompiling software, examining components, testing hypotheses and recording results long after its human operator has gone home.
AI-Powered Propaganda Is Becoming Infrastructure
Cyberattacks occupy a large portion of Anthropic’s report, but the findings around political influence operations are equally significant.
Anthropic says it disrupted nine influence campaigns originating from regions including Russia, Iran, Turkey, the Gulf, South Asia, Africa and Europe.
Those operations targeted audiences across six continents and involved governments, state-aligned media organizations, private influence contractors and domestic political actors.
AI was not simply being used to write political posts.
It was being used to help construct the infrastructure surrounding propaganda campaigns.
Actors reportedly used Claude to create fake personas, political dossiers, target databases, editorial guidelines, propaganda doctrine, fake news operations and software for managing coordinated accounts.
Persistent files could contain approved narratives, banned phrases and operational instructions, allowing multiple people to produce coordinated propaganda without directly coordinating with each other.
One commercial influence operation reportedly published at least 8,913 articles in around 20 languages across approximately 70 fabricated news websites.
Another operation targeting Malaysia reportedly involved around 1,000 fake X accounts, voter and census information, a fabricated news outlet and false intelligence dossiers targeting political opponents.
But the report contains an important reality check.
Producing propaganda cheaply does not automatically make that propaganda successful.
Anthropic says many of the influence operations it discovered generated little or no genuine engagement. The campaigns with the widest authentic reach generally had access to established distribution systems such as radio, television or state media.
AI can make propaganda production dramatically cheaper.
It cannot automatically manufacture credibility.
That is an important distinction.
Anthropic has been documenting similar misuse for some time. Its August 2025 AI misuse report had already warned that agentic AI was beginning to move from merely advising attackers toward actively participating in sophisticated operations.
The 2026 report suggests that transition has accelerated.
AI-Powered Surveillance May Be Even More Disturbing
The surveillance section may be the darkest part of the document.
Anthropic says it discovered activity involving state-linked actors, contractors and commercial surveillance organizations associated with China, Iran and West Africa.
Three patterns stand out.
The first is that AI can substitute for engineering manpower.
Anthropic describes a single consultant working with Malian national security authorities who used Claude while engineering a mass-interception platform intended to work across the country’s mobile operators.
The second is the ability to process enormous quantities of information.
In one investigation, an actor uploaded social media material and used Claude to transform it into structured intelligence containing locations, demographic information and political leanings.
An Iranian operation reportedly analyzed hundreds of thousands of social media posts and selected 39 opposition accounts for monitoring.
The third trend is institutionalization.
AI is no longer necessarily being used as an experimental side project.
Anthropic says it observed AI becoming part of ordinary state security bureaucracy, including the creation of internal guidance for using AI during surveillance work.
In another particularly striking case, a PRC-aligned operator who apparently lacked Arabic-language skills allegedly used Claude during a multiday operation involving Uyghur targets in Syria.
The model generated communication in Syrian Arabic, translated responses, helped evaluate the deception and assisted with packaging the intelligence generated by the operation.
Language once created friction.
AI can remove much of it.
That matters when the organization using AI is conducting surveillance rather than customer support.
AI Is Already Touching Real Weapons Programs
The report also describes six investigations involving conventional weapons activity.
Three involved actors in China, two involved Russia and one involved Yemen.
According to Anthropic, the cases included software associated with guided rockets, drone swarms, electronic warfare, torpedo interception, defense procurement and intelligence gathering related to weapons technology.
One Yemen-based group was reportedly working on several guided missile programs, including a guided rocket and longer-range missile systems.
This does not mean somebody typed “build me a missile” into Claude and received a complete functioning weapon.
The report makes an important distinction.
In several cases, the users already possessed domain knowledge, hardware access or engineering expertise.
AI provided additional software-development and analytical capability.
Once again, the key concept is uplift.
AI does not necessarily create an expert from nothing.
It can make an existing expert significantly more productive.
Biology Creates an Even Harder Safety Problem
Biological research introduces another complication because legitimate and dangerous scientific research can overlap.
Anthropic says earlier models were clearly below the threshold at which they could substantially assist sophisticated actors with dangerous biological research.
For newer frontier models, the company says the evidence is less certain.
That uncertainty has resulted in stronger safeguards around sensitive biological topics.
Anthropic describes five investigations involving research that could potentially support biological weapons development.
Those included work relating to chikungunya gain-of-function research, avian influenza mammalian adaptation, orthopoxvirus immune evasion, venom peptides and computational redesign of toxins.
Anthropic is also careful about what it claims.
The company explicitly says it is not alleging that the scientists necessarily intended to create biological weapons.
That ambiguity is the problem.
Research that could contribute to vaccines, medical treatments or defensive science can sometimes overlap with information useful for harmful applications.
There may be no obvious malicious prompt for a safety system to catch.
The broader challenge is discussed throughout Anthropic’s Responsible Scaling Policy, which ties progressively stronger safeguards to increases in model capability.
Then There Is the AI Dating Scam Factory
Buried near the end of the report is one of its strangest cases.
A China-based company allegedly built a network of more than 20 dating apps powered partly by Claude.
The apps were presented as interactions with real people.
Anthropic says that during a two-week period in April 2026 it identified more than 4,700 AI personas interacting with at least 25,000 people.
The operator also hired real gig workers and mixed their profiles into the dating feed.
The ratio was approximately three AI personas for every real person.
Humans handled interactions that were more difficult for AI to fake convincingly, such as live video calls and genuine social-media follows.
Claude-powered personas reportedly generated around 2.36 million messages during the two-week period.
The bots were instructed not to reveal that they were automated.
The backend could generate fake likes and visits, use prerecorded video when necessary and even track which users appeared to suspect they were speaking to bots.
This might be one of the simplest demonstrations of AI’s effect on fraud.
AI does not need to invent a revolutionary new scam.
It simply needs to make an existing scam cheap enough to run against thousands of people at once.
The AI Companies Are Apparently Going After Each Other Too
The final section introduces another battlefield entirely.
AI models themselves have become valuable enough to steal from.
Anthropic calls the practice illicit distillation.
Distillation is normally a legitimate AI training technique in which a smaller model learns from the outputs of a larger, more capable model.
Anthropic defines illicit distillation as covertly extracting those capabilities at industrial scale without authorization.
The company says it disrupted campaigns associated with seven China-based AI labs.
The largest allegation concerns Alibaba.
Anthropic says operators affiliated with Alibaba generated more than 151 million exchanges during a distillation campaign between May and July 2026, at one point approaching three million exchanges per day.
The report also makes allegations involving Moonshot, DeepSeek, Zhipu, Xiaomi, SenseTime and MiniMax.
Some of the findings raise concerns beyond intellectual property.
Anthropic alleges that Moonshot and DeepSeek routed some customer requests to Claude without users necessarily knowing that another AI provider was processing them.
According to the report, some of those exchanges contained sensitive corporate information, internal credentials and surveillance-related material.
Xiaomi is similarly alleged to have replayed user conversations and coding sessions through Claude as part of training-related activity. Anthropic says some exchanges contained personal or corporate data.
These are Anthropic’s findings and attributions, and that distinction matters when discussing named companies.
But the broader lesson applies regardless of how individual allegations are disputed.
Your AI provider is now part of your data supply chain.
So is the router.
So is the wrapper.
So is the proxy.
So is any third-party service sitting between you and the model you think you are talking to.
The Real Warning Is Not Superintelligence
The easiest mistake would be to read the report as another argument about hypothetical artificial general intelligence.
Most of the systems documented here do not need to be superintelligent.
They only need to be useful.
Useful enough to write code.
Useful enough to translate conversations.
Useful enough to process thousands of documents.
Useful enough to impersonate someone.
Useful enough to classify targets.
Useful enough to coordinate other AI agents.
Useful enough to continue working while the human operator is asleep.
Anthropic says malicious actors repeatedly attempted to circumvent safeguards using account rotation, proxies, stolen API credentials and other techniques.
The company says it responded through account bans, behavioral detection, new classifiers, protected reasoning systems and intelligence sharing with governments and other technology companies.
Anthropic has also developed systems such as Clio for identifying coordinated misuse patterns that may not be obvious when individual conversations are examined in isolation.
But no safeguard permanently ends the problem.
AI security is becoming adversarial.
Developers build controls.
Attackers study those controls.
Developers respond.
Attackers adapt.
That cycle will probably look increasingly familiar to anyone who has worked in cybersecurity.
What Should Actually Worry Us
The biggest revelation in Anthropic’s report is not that criminals and governments discovered AI.
Every useful technology eventually gets abused.
The more consequential development is that AI appears capable of reducing the minimum number of people required to run a sophisticated operation.
One hacker can coordinate agents.
One propagandist can operate something resembling a newsroom.
One engineer can build systems that previously required a team.
One scam operation can maintain thousands of simultaneous conversations.
One intelligence analyst can process information that once required an entire department.
That does not eliminate human expertise.
Humans still provide the intent, objectives, infrastructure, judgement and domain knowledge in many of these cases.
What AI changes is the enormous amount of work sitting between deciding to do something and actually doing it.
For years, the loudest AI debate has revolved around one question:
What happens when artificial intelligence becomes smarter than humans?
Anthropic’s report suggests there may be a more immediate question.
What happens when one human suddenly gains the operational capacity of an entire team?
We may already be finding out.

One publishing note: I’d keep the wording “Anthropic says,” “Anthropic alleges,” “according to Anthropic,” around the named-company allegations. That protects the article from presenting one company’s threat-intelligence attribution as independently proven fact.
