A Russian website called CyberLover.ru is advertising a software tool that, it says, can simulate flirtatious chatroom exchanges. It boasts that it can chat up as many as 10 women at the same time and persuade them to hand over phone numbers.An Australian anti-virus software firm, PC Tools, has warned that the software could be abused by identity fraudsters trying to harvest people's personal details online. The Russian site denied it was intended for identity fraud.
