Opera Software Suffered a Security Breach, No Evidence of Stolen User Data
Fortunately for Opera browser users, Opera Software doesn't believe that any user data was stolen or otherwise compromised in the attack, adding that current evidence suggests the attack had "limited impact."
"On June 19th we uncovered, halted, and contained a targeted attack on our internal network infrastructure," Opera Software stated in a blog post. "Our systems have been cleaned and there is no evidence of any user data being compromised. We are working with the relevant authorities to investigate its source and any potential further extent. We will let you know if there are any developments."
As for the malicious code, Opera Software said it's possible that a "few thousand Windows users" running Opera between 1:00 AM and 1:36 AM UTC on June 19th may have automatically received and installed a bogus update. All Opera browser users are encouraged to update to the latest version.
