Opera’s Fraud and Malware Protection warns you about suspicious webpages and is enabled by default. It checks the page you request against several databases of known phishing and malware websites, called a blacklists. Although it is not possible to totally eliminate the risk of encountering an unidentified phishing or malware website, the risk is minimized.
Note that checking against the database does not delay the opening of webpages.
The explosive growth of Internet commerce has given rise to a new breed of online criminals who may attempt to steal your passwords, your credit card numbers, and other personal information by impersonating authority figures from your bank or other institutions you frequent. The best defense against this growing threat is to be aware of the problem and to be alert when transacting business online.
Fraud of this kind is often called phishing, and in analogy to fishing, your private information is the catch. There is more than one kind of bait, but the most common type is email, apparently from your bank, coupled to a website resembling your bank’s — so precisely copied that you may not discern the difference. You will be encouraged to log in and “verify” your customer information: in other words, to reveal your password, credit card number, or other private data.
For the same reason that you have anti-virus software installed, you may want protection from websites that distribute viruses or other malicious software, collectively known as malware. The concept of malware encompasses not just viruses, but also scripts that may run automatically when you load a webpage.
With Opera Fraud Protection enabled, every webpage you request is subjected to phishing and malware filters. The security status of the page is displayed in a security bar in the address field. Indicators in this bar tell you about the level of security the protocol (HTTPS or HTTP) provides, the validity of the certificate, or whether it has been blacklisted.
A maximally secure site has the following features:
The table below describes the security bar indicators used in the Opera browser:
|Security bar indicator||Protocol||Status|
|HTTPS||Maximally secure site, with Extended Validation (EV)|
|HTTPS||Secure site, where the credentials of the site owner have been checked|
|HTTPS||HTTPS site with problems or where information is not available to enable verification|
|Any||Blacklisted site, with Fraud Site warning|
If a website is found on the blacklists, a warning page displays before the page is shown. You must decide whether to visit the questionable website, to return safely to the browser home page, or to read additional information about the status of the page. If you open a phishing or malware page, it will be marked with a red “Fraud Site” indicator, as shown in the table above.
To display more detailed security information, including information about the website’s certificate, click the security bar. To view this information for any webpage, you can also select Security Information dialog topic.. In this dialog, you can also report a site as suspicious, or enable/disable Fraud Protection.
