The Norwegian browser maker allows anyone to sign up and host photos, upload files, publish blogs, participate in discussions and more at myOpera. Unfortunately, the ease of creating an account is being exploited by malware developers to host PHP based IRC botnets on myOpera.
In the recent past, malwares were discovered on Mozilla and Google Code’s servers also. Although I am still awaiting an official response from Opera regarding the security measures they currently have in place, by Kaspersky’s own admission, the problem isn’t very widespread. Dmitry Bestuzhev, the expert from Kaspersky who made the discovery, has so far found less than hundred malwares hosted on myOpera, which has more than 5 million registered members.
Incidents like this goes on to prove that staying careful alone can’t always protect you. XSS vulnerabilities in popular websites like Twitter and YouTube, HTML injection attacks in popular blogs and untrusted files on community websites like myOpera are just some of the techniques being used by malware creators to fool even savvy internet users.
