- SecurityWeek said at least a dozen AI developer platforms were hit over the past month.
- Chainstack’s accessed database may have exposed customer names, member email addresses and password hashes.
- WorkOS said hackers accessed sales-application data including business contacts and customer account histories.
The incidents reached different types of customer and business information. Chainstack said an accessed database contained organization names, account-holder names, member email addresses and password hashes. WorkOS said attackers accessed business contact details and summaries of customer communications.
SecurityWeek said the campaign included Andromeda, Brev, CommandCode, Fireworks AI, Lightning AI, Northflank, OpenCode, Railway, Trigger.dev, Warp and Zeabur. The Cloud Security Alliance said attackers were reaching AI-provider credentials through hosting platforms, evaluation services and developer consoles. Wiz published its report on Oct 30, 2026.

Chainstack and WorkOS disclosed attacks that relied on Artex
Chainstack and WorkOS disclosed attacks that relied on the open-source Artex AI penetration-testing framework for automation. SecurityWeek said the attacks did not appear related, and that initial access varied across incidents, including compromised credentials, third-party dependencies and vulnerability exploitation.
The company said attackers reached a development environment and parts of its production environment through a third-party component. Chainstack said the accessed database contained customer account information, and that node credentials might also have been exposed because attackers reached systems storing them.
Hackers appeared to hunt for AI access tokens
SecurityWeek said the hackers appeared to be hunting for AI access tokens they could monetize and relied on AI agents to speed up and streamline attacks. Wiz said the rise was driven by LLM-jacking and LLM-broker infrastructure, which made AI access tokens monetizable.
Fireworks and Andromeda reported separate credential incidents
Andromeda said it identified unauthorized credential access on October 13, disabled compromised accounts that day and observed no further unauthorized activity. It said the activity began as part of an industry-wide attack around October 9 and affected a limited number of customer accounts.
Wiz said two compromised enterprise credentials had identical first unauthorized activity within 30 minutes of reported credential access within the vendor breach.
Chainstack prompted customers to rotate node credentials. Fireworks told affected customers to replace revoked API keys and update applications that used them.
Wiz observed multiple threat actors using the same compromised keys, which “suggests a robust market for this type of credential”. SecurityWeek said multiple companies linked attacks attributed to the Chinese APT Storm-0940 to use of the Artex framework.
What to do now
- Rotate your Chainstack node credentials.
- Replace revoked Fireworks API keys, create new keys in your Fireworks account and update the applications that used the revoked keys.
FAQ
What happened in the AI developer platform attacks?
SecurityWeek said hackers targeted at least a dozen AI developer platforms over the past month, seeking AI access tokens they could monetize. It said the attacks did not appear related and used different initial-access methods.
Which AI developer platforms were targeted?
SecurityWeek named Andromeda, Brev, CommandCode, Fireworks AI, Lightning AI, Northflank, OpenCode, Railway, Trigger.dev, Warp and Zeabur. It also reported attacks on Chainstack, while WorkOS disclosed an attack on an internal application.
What data did the Chainstack attackers access?
Chainstack said an accessed database contained organization names, account-holder names, member email addresses and password hashes. SecurityWeek said node credentials might also have been exposed because attackers accessed systems storing them.
What information did the WorkOS attackers access?
WorkOS said hackers compromised an internal sales application and accessed business contact details and summaries of customer communications, including names, email addresses, phone numbers, job titles, company affiliations and customer account histories.
What is Artex in these attacks?
SecurityWeek reported that Chainstack and WorkOS disclosed cyberattacks that relied on Artex, an open-source AI penetration-testing framework, for automation.
How should affected customers respond?
Chainstack prompted customers to rotate node credentials. Fireworks instructed affected customers to replace revoked API keys, create new keys and update applications that used the revoked keys.
