Hackers have used an email account stolen from another company to target an unsuspecting consumer, according to security researchers.

Robins Hood, a company that sells security software, reported the issue to Twitter on Wednesday.

The company said it notified the hacker that it was aware of the issue and offered to reimburse the victim for his or her costs, but the hacker declined.

The hacker, whose name was not released, claimed responsibility for the attack, and told researchers at the Black Hat cybersecurity conference that the company would not be making any changes to the software.

“As a company, we are committed to keeping our customers safe and will not be updating any of our products,” Robins said in a statement.

A spokeswoman for Robins declined to comment.”

While we have not yet received any reports of our customers receiving malware from this incident, we have also taken steps to ensure that our software is being updated to the latest standards and we are actively investigating and addressing the incident.”

A spokeswoman for Robins declined to comment.
