Opera has confirmed that they faced an attack against company’s internal network few days back and successfully halted it. The attack took place on June 19 and there is no evidence that user data has been compromised. But attackers have managed to cause some damage to Opera Software.
Company confirmed that attackers stole at least one old and expired Opera code signing certificate, which they have used to sign malicious software. These malicious software incorrectly appears to have been published by Opera Software or Opera browser. But it had limited impact
“It is possible that a few thousand Windows users, who were using Opera between 01.00 and 01.36 UTC on June 19th, may automatically have received and installed the malicious software. To be on the safe side, we will roll out a new version of Opera which will use a new code signing certificate,” Opera noted in blog.
Company also requested users to update their Opera to latest version as it is available Keeping all software and Antivirus up to date is a good practice to keep yourself secure.
Opera is trying to get more details of the attack. It will roll out new version of Opera soon that will use new code signing certificate.
