Some sites and viruses that exploit the recent tsnunami grief have appeared on the web.
There is for instance a fake Red Cross website that is aimed to collect credit card information from visitors by making them believe it's the genuine website of the Red Cross. The site doesn't only ask credit card numbers but also PIN numbers.
Another malicious attempt to deceive people is the VBSun-A worm which pretends to offer details on how to contribute to people who lost their homes by the tsunami disaster. The e-mails have headers as "Tsunami Donation! Please help!". The worm contains an attachment called tsunami.exe - don't open it if you receive it.
