Software auditing tool maker Codecov has had its systems breached and the attackers are now reportedly using its bash uploader script to gain access to hundreds of its customers' networks.

The attackers were able to modify the upload script and gained access to do this because to a mistake in its creation of a Docker image.

Codecov said in a statement issued on 15 April that it became aware of the incident on 1 April, but there had been unauthorised entry to its systems from 31 January onwards. Reuters claimed the attackers had gained access to other companies using Codecov's product.

Codecov has about 19,000 customers, among them Hewlett Packard Enterprise, IBM, Procter & Gamble, GoDaddy, The Washington Post, and Atlassian Corporation.

Codecov chief executive Jerrod Engelberg said from 31 January, there had been periodic, unauthorised alterations of the Bash uploader script by a third party, "which enabled them to potentially export information stored in our users' continuous integration environments. This information was then sent to a third-party server outside Codecov’s infrastructure".

He said the bash uploader was also used in the Codecov-actions uploader for GitHub, the Codecov CircleCl Orb, and the Codecov Bitrise Step. The related uploaders were also affected.

"The altered version of the bash uploader script could potentially affect:

"Any credentials, tokens, or keys that our customers were passing through their CI runner that would be accessible when the Bash Uploader script was executed.

"Any services, datastores, and application code that could be accessed with these credentials, tokens, or keys.

"The git remote information (URL of the origin repository) of repositories using the bash uploaders to upload coverage to Codecov in CI," Engelberg said.

He said that companies which were hosting their own Codecov on-premises were unlikely to have been affected. But those who were fetching the bash uploader from Codecov's servers were likely to have been affected.

Update: An Atlassian spokesmen said: "We are aware of the claims and we are investigating them. At this moment, we have not found any evidence that we have been impacted nor have we identified signs of a compromise."
