GitHub, the top software development platform in the world, made some users reset their passwords after discovering an issue that resulted in credentials being recorded in plain text in internal logs.
A routine corporate audit uncovered the problem, which involved some users sharing on Twitter the email correspondence that the organisation had received.
The business promptly stated that user data was safe and that none of its systems had been compromised.
The business further stated that the plaintext passwords were not publicly available and could only be seen by a limited number of its IT workers through internal log files.
