Fighting cybercrime

The Web, it’s said, is full of stranger-danger. Experts advise wariness of unknown emails, faux-links and file attachments. But while we may be rightfully wary of strangers, danger frequently masquerades as friends.

Email spoofing—the forgery of message headers—allows e-miscreants to trick recipients into opening errant emails. The payoff may be simple spam or outright cybercrime: phishing attacks to gain personal information, identify theft, the spread of malicious code to gain control of a computer, denial of service attacks. Such email may appear to come from one’s own account (common with spam), a friend (as from email address book harvesting viruses) or an institution of authority like a bank, an online retailer or a government agency (all common in phishing attacks). The IRS, Social Security, the FBI and the Department of Justice all have reported that fraudulent emails have been circulated as if sent by them. Spoofed Web sites pose a similar threat.
