Scott Farquhar started a war of words with Musk over Musk's return to work policies. Farquhar has a $48 billion software company that is dealing with a hacker problem.

Musk, the world's richest man, made waves earlier this week when a leaked email he sent to his employees revealed how he felt about working from home.

Musk announced that white- collar employees who don't report to the office at least 40 hours a week can start looking for a new job.

Farquhar's Atlassian appears to have taken that seriously.

Farquhar likened Musk's declaration to something out of the 1950s and highlighted the importance of fully embracing working from home as a key for continued growth. He ended the thread with a link to apply for a job at Atlassian.

It wasn't long before Musk responded to Farquhar with a jab of his own.

In the past, Musk has criticized Bill Gates and Jeff Bezos on the social networking site. The current controversy surrounding Atlassian's security protocols wasn't mentioned by him.

Atlassian, which was founded in 2002 and now competes directly with established developers, hit a $100 billion market cap last year. It recently issued an advisory warning about a "critical severity" security flaw in its products after detecting multiple instances of "current active exploitation" by external parties.

One of the company's best-selling products is being affected by a bug. It is emphasized on the website that it is a "remote-friendly team workspace."

According to reports, the security flaw has been a problem for the company for a while. According to tech news outlet The Register, the bug's history was traced back to the release of a version of Confluence.

Users have been told not to expose their software to the internet until a patch is released.

It isn't the first time that weaknesses in the server have been seen as vulnerable to hackers. A serious vulnerability in the privacy protocols of the product could allow attackers to access the server and execute code without authorization.

One of the problems with companies allowing employees to work from home indefinitely is cybersecurity concerns. Security issues with essential remote-work products like Confluence are just one reason to ask employees to return to the office.

It was not out of the 1950s.
