Aoki infostealer adds AI coding assistant tokens and AWS keys to its target list, Symantec says

Symantec says new Aoki infostealer versions steal API keys and tokens for AI coding assistants, plus AWS credentials, from infected machines. The firm says threat actors now value such credentials like payment card data.

Stolen AI keys can expose repos and cloud services What Aoki's newest version steals and where a stolen AI key or token leads, according to Symantec researchers.

Map: Aoki's newest version steals AI coding assistant tokens and AWS credentials. A stolen AI key can be resold or run up usage on the victim's account, bypass safeguards that assume a trusted user, and expose repositories, cloud services and CI/CD pipelines.

What happened

  • Earlier Aoki versions focused on browser, cryptocurrency wallet and password manager data and did not touch AI-related files.
  • The newest version Symantec's Threat Hunter Team found targets .claude.json, Claude desktop cookies, ChatGPT cookies, and Codex config.toml and .env files.
  • It also takes tokens for GitHub Copilot, Cursor, Gemini, JetBrains AI Assistant and Kiro, along with AWS credentials.
  • Symantec published the report on October 15 and describes Aoki as relatively new and sparsely documented, first observed earlier in 2026.

Why it matters

  • What it costs cost Usage run up through a stolen key lands on the victim's account, so the account holder carries the bill for resold or consumed capacity.
  • What it limits constraint Controls keyed to the developer's identity have nothing to flag: Symantec says requests made with a stolen token bypass safeguards that assume a trusted user.
  • Who's exposed exposure Cleanup has to cover cloud and repository access as well as the AI accounts. One infected developer endpoint can give up AI tokens and AWS credentials in the same pass.

Aoki is one stealer family adding targets. Symantec said the ability to steal AI-related files is recent and appears to be expanding [10]. The firm added: "Aoki is a highly capable and multi-functional infostealer whose capabilities still appear to be in active development," Symantec added [11].

Symantec separated two uses of a stolen key. In the researchers' words: "Like card data, a stolen AI key can be cashed in directly, either through resale or by running up usage on the victim's account, a practice sometimes called LLMjacking. Unlike card data, it can also give an attacker a route into the developer's wider environment," they explained [12]. The first use is a billing event. The second is an intrusion, because the same tokens can expose connected repositories, cloud services and CI/CD pipelines linked to that account [6].

We think the second use sets the response scope. A machine hit by the newest version has to be treated as having lost every item on the target list, and revocation is a separate step for each service on it.

Nobody has put a name on the operators. Symantec said it does not know which threat group may be behind Aoki, and it sees no indications of links to an existing malware family [7]. The financial motive is an inference from the rest of the target list, which focuses on cryptocurrency wallets and extensions [8].

SC Media's brief says it is based on information published by Infosecurity Magazine, and both trace to the one Symantec report [14]. Symantec's view that AI credentials now rank with card data is drawn from Aoki's development [13], so in the coverage it rests on a single family's target list. The coverage does not say how Aoki reaches a machine or how many victims it has, and it cites no CVE.

What to watch

  • A named actor or a link to an existing malware family, since Symantec says it has neither today.
  • New target files in later Aoki builds, given Symantec's finding that the AI-file theft appears to be expanding.
  • A documented intrusion in which a stolen assistant token reached a repository or CI/CD pipeline; the coverage describes that exposure as possible.
