If you're one of millions using element-data, it's time to check for compromise [arstechnica.com]:

Open source software with more than 1 million monthly downloads was compromised after a threat actor exploited a vulnerability in the developers' account workflow that gave access to its signing keys and other sensitive information.

On Friday, unknown attackers exploited the vulnerability to push a new version of element-data [github.com], a command-line interface that helps users monitor performance and anomalies in machine-learning systems. When run, the malicious package scoured systems for sensitive data, including user profiles, warehouse credentials, cloud provider keys, API tokens, and SSH keys, developers said [elementary-data.com]. The malicious version was tagged as 0.23.3 and was published to the developers' Python Package Index and Docker image accounts. It was removed about 12 hours later, on Saturday. Elementary Cloud, the Elementary dbt package, and all other CLI versions weren't affected.

"Users who installed 0.23.3, or who pulled and ran the affected Docker image, should assume that any credentials accessible to the environment where it ran may have been exposed," the developers wrote.

The threat actor gained access to the developers' account by exploiting a vulnerability in a GitHub action they created. By posting malicious code to a pull request, the attackers were able to run a bash script that ran inside the developer's account. The bash script retrieved the sensitive data. With the account tokens and signing keys, the attacker went on to publish a malicious element-data package that was nearly indistinguishable from a legitimate one.

[...] Over the past decade, supply-chain attacks on open source repositories have become increasingly common. In some cases, they have achieved a chain of compromises as the malicious package leads to breaches of users and, from there, breaches resulting from the compromise of the users' environments.

HD Moore, a hacker with more than four decades of experience and the founder and CEO of runZero, said that user-developed repository workflows, such as GitHub actions, are notorious for hosting vulnerabilities.

It's a "a major problem for open source projects with open repos," he said. "It's really hard to not accidentally create dangerous workflows that can be exploited by an attacker's pull request."

He said this package [github.com] can be used to check for such vulnerabilities.

TFA mentions steps to take if you downloaded version 0.23.3.
