The makers of the Opera browser has confirmed last week that a security breach has been discovered in their systems of 18 e June and accordingly, a few thousand users may unknowingly download malicious software on their computers.
In a statement issued on 26 June, the company rushed to reassure users that no personal data had been stolen and that the violation had been fixed, but warned that hackers had made off with Opera at least one code-signing certificate that had been used to disguise malware as an update of the browser. The company already has evidence that this certificate is attached to a type of malware Trojan and said they identified first in use for a period of about 36 minutes to 18 e June
It might not seem like a big deal, but a digital certificate is often the only thing that distinguishes an authentic updating of the company from a hacking attempt carefully planned and detailed. By releasing malware in the digital signature of the Opera, thousands cautious users could end up with a Trojan downloader that they certainly did not sign for.
The users who were online and using the browser on 18 e June are invited to go to the official website of the Opera and download the latest browser version, before launching a comprehensive analysis of the computer with their anti-virus software. However, even users who are not online the day are advised to be careful, because hackers can still try to attach the certificate to more malware in the future.
In a blog post about the recent hack, Symantec has observed that the nature of the attack contained may actually have been deliberate on the part of the pirates. They stressed that the software access period more would become very "noisy" and would have immediately alerted the security systems in the presence of malware. As it is, Opera seems convinced that the attack and its consequences were quickly processed.
