Firefox, like other web browsers, usually displays text in HTML mode. Seeing a "link" for https://gaibacoupontec.com does not guarantee the hidden 'A HREF' code is actually for that site. > Is it possible that a new Firefox flaw has been detected and is > being exploited for malicious purposes? Yes. Alertness and improving security are continuous tasks. SQL injection attempts, made by suffixing usually very long strings of SQL coding to valid parameters such as domain.com/info.php?aaaa=12345, has been popular with the Russians for at least the last few years. The only method of preventing it compromising a site is to test the acceptable maximum length of the parameter (in this example '12345') and if exceeded block the IP address in iptables. Cyber attacks are gradually replacing armed conflicts. -- Regards, Paul. England, EU.
