World's First AI Agent Ransomware Attack Exposed: It Found the Vulnerability Itself, Stole the Keys Itself, Encrypted the Database Itself—Then Screwed It Up

On July 3rd, the Sysdig security team dropped a bombshell: the world's first fully documented ransomware attack executed entirely autonomously by an AI Agent was captured. The attacker, codenamed JADEPUFFER, went from vulnerability exploitation to database encryption with zero human involvement.

This isn't science fiction. This actually happened last week.

The Entry Point: A Hole That Was Patched and Then Left Open

The attack started with a Langflow service exposed to the public internet. This low-code AI development platform carries a critical vulnerability, CVE-2025-3248—remote Python code execution requiring no authentication whatsoever. Langflow patched it back in version 1.3.0, and CISA added it to its "Known Exploited Vulnerabilities" catalog last year. But a massive number of instances are still running naked on the internet, and JADEPUFFER slipped right in along that line.

The first thing it did after gaining host control: loot everything of value.

The Looting List

The AI automatically harvested from the victim machine:

• LLM API keys—OpenAI, Anthropic, DeepSeek, Gemini, not a single one missed
• Cloud platform credentials—Alibaba Cloud, Tencent Cloud, Huawei Cloud, AWS, Google Cloud, Azure
• Database accounts, configuration files
• Cryptocurrency wallets and seed phrases

What's even more chilling: it also scanned and found a MinIO object storage instance, and successfully logged in using the default credentials "minioadmin"—how many teams just never bother changing default passwords after deployment? It all blew up at once.

Then it planted a scheduled task on the server: a callback to the attacker-controlled server every 30 minutes. This wasn't a drive-by hit; this was putting down roots.

Lateral Movement: Old Vulnerabilities Plus Default Keys, AI Stitching It All Together

With enough information in hand, JADEPUFFER turned its sights on another server running production workloads—hosting MySQL and Alibaba's open-source configuration center, Nacos.

The AI logged directly into MySQL using the database Root account, then exploited CVE-2021-29441 (a Nacos authentication bypass vulnerability) combined with an never-changed default JWT signing key to breach the configuration center. It then planted a hidden administrator account in Nacos, securing full control over the entire configuration center.

Sysdig specifically highlighted something: the AI failed on its first attempt to create the admin account. A human would just retry—the AI took only 31 seconds to complete error analysis, regenerate the password hash, delete the failed account, recreate it, and verify the login again. The entire remediation process was fully automated, with no human engineer in the loop.

The attack executed over 600 attack payloads in total, with each step adjusting subsequent strategy based on the execution results of the previous one.

The Encryption: 1,342 Records Locked Down, Then a Blunder

At the ransomware stage, JADEPUFFER used MySQL's built-in AES_ENCRYPT() function to encrypt all 1,342 configuration records in Nacos. It then deleted the original configuration tables and history tables, leaving behind a table named README_RANSOM—containing a Bitcoin wallet address and a Proton Mail contact for the ransom demand.

The entire attack chain was clean and efficient, looking like a mature ransomware pipeline already.

But then came a fatal blunder.

After generating the encryption key, the AI output it to the terminal exactly once—without saving it, without uploading it.

That means even if the victim pays the ransom, the attacker doesn't have the decryption key either. The data is completely unrecoverable. Sysdig also found that the AI claimed the data had been backed up to an external server, but researchers found no evidence of any data exfiltration. It reads more like a line the model "thought it should say" than something that actually happened.

What You Should Actually Be Afraid Of

JADEPUFFER didn't use any new vulnerabilities or invent any new techniques. It simply strung together a bunch of known, publicly documented attack methods—the key difference being that it was the AI itself doing the stringing.

Sysdig's assessment is worth reading three times by every security leader: this case proves that AI Agents are already capable of autonomously completing the full chain of vulnerability exploitation → privilege escalation → credential theft → lateral movement → persistence → ransomware destruction. The barrier to entry for attacks has been dramatically lowered. You no longer need a penetration tester sitting at the keyboard—all it takes is someone pointing an AI Agent at an internet-exposed service.

How to Defend

Sysdig's recommendations are pragmatic and to the point:

• Upgrade Langflow—don't leave code execution interfaces exposed to the public internet
• Change the Nacos default JWT signing key—this hole has been public since 2021
• Don't use Root accounts for external database services
• Strengthen runtime behavior detection and restrict server outbound communications
• Manage all types of access credentials properly

Everyone knows the drill, but JADEPUFFER tells us this: now AI will use these very lessons to attack you. The days of leaving default passwords unchanged and known vulnerabilities unpatched might truly be over.
