The security company, Sophos from the United Kingdom, notified its customers via email about a security breach it suffered earlier this week.
"On November 24, 2020, Sophos was notified of an issue authorizing access to a tool used to store information from customers who have contacted Sophos Support," the company said in an email sent to its customers.
Exposed information included details such as customer name and surname, email addresses and telephone numbers (if provided).
One millionfaceA Sophos spokesperson confirmed the messages and told ZDNet that a "small subset" of the company's customers were affected, but did not give an approximate number.
Sophos said it learned of the incorrect settings from a security researcher and immediately corrected the issue.
“At Sophos, customer privacy and security is always our first priority priority. We are contacting all affected customers. In addition, we implement additional measures to ensure that access authorization arrangements are always secure.”
This is the second major security incident faced by Sophos this year. In April, a team discovered that a 0day in the Sophos XG firewall was being used to breach Companies σε όλο τον κόσμο.
