A major AI company “Anthropic” has revealed a shocking case of cybercrime. Hackers with little to no technical skill used its chatbot to carry out phishing schemes, ransomware demands, and data theft. The company confirmed that the criminals misused its AI system to automate cyberattacks, write ransom notes, and even calculate extortion fees.

How the Hackers Misused Anthropic’s Claude AI chatbots

The report says this marks one of the most alarming examples of “agentic AI” being turned into a weapon. According to the company, the attacks targeted at least 17 organizations, though the names of the victims remain undisclosed. In some cases, ransom demands reportedly went as high as $500,000.

The misuse was made possible through what the report calls “vibe hacking.” This term refers to criminals using plain English instructions to manipulate the chatbot into generating harmful code, creating tailored phishing campaigns, and designing malware without needing any traditional hacking expertise.

The hackers reportedly tricked the chatbot into completing tasks that would normally take skilled coders days or weeks. By entering simple prompts, they were able to identify companies with weak digital defenses. The chatbot was then pushed to build harmful software designed to steal data. It also created realistic phishing emails that appeared genuine to unsuspecting victims.

In addition, the chatbot was used to write ransom demands and even generate threatening notes that looked alarming. The criminals further relied on the AI to organize stolen information. The chatbot helped them sort files, plan their actions, and quickly move between different stages of the crime.

Company’s Response to the Attack

The AI startup responded by immediately suspending the accounts linked to the abuse. It also tightened its safety filters to prevent similar misuse in the future. The company shared cybersecurity best practices with businesses, stressing the urgent need for vigilance as AI-powered threats continue to grow.

It advised companies to strengthen their basic cyber hygiene. Employees should be trained to recognize phishing attempts and encouraged to use complex passwords. Multi-factor authentication was also highlighted as an important defense against attackers.

The report further encouraged organizations to seek help from cybersecurity professionals. Regular audits and security checks were described as necessary steps to identify risks before they are exploited. This was emphasized as especially important for businesses that handle sensitive customer or financial data.

Monitoring new AI-related risks was also recommended. Business owners were urged to follow reports from AI providers and experts so they can stay updated on emerging threats. Since AI tools can be used for both positive and harmful purposes, awareness is seen as a key part of defense.

Finally, the company noted the importance of partnerships. Joining industry groups or networks that share intelligence can help organizations prepare faster. These groups allow companies to warn each other about new scams and learn from best practices.

Why This Matters for Businesses

The report makes clear that cybercrime has changed. Hackers no longer need advanced knowledge to carry out damaging attacks. With the help of AI chatbots, even people with no technical background can now launch large-scale operations.

In this case, the attackers demanded ransom amounts of up to half a million dollars. While it is still unknown how much money they collected, the scale of the scheme shows how dangerous AI-powered crime can become.

By exposing how its chatbot was misused, the company has attempted to alert businesses of all sizes. It stressed that both large corporations and small firms are at risk if they do not adopt stronger defenses. The misuse of AI for phishing, ransomware, and extortion is described as a fast-growing threat that must not be ignored.

The company has stated that it has contained the immediate risk and suspended the accounts responsible for the abuse. It has also strengthened its safeguards and given guidance to businesses on how to stay protected. The incident stands as a serious warning that criminals are finding new ways to exploit AI, and organizations must act quickly to reduce their chances of being targeted.
