Update: FBI warns of fake e-mail scam
The hoax e-mails, purportedly from the FBI itself, try to get users to launch a virus
Computerworld - A mass e-mail purportedly from the FBI is circulating online, carrying with it an attachment that contains a variant of the Sober computer virus.
In an announcement today, the FBI advised computer users that the agency never sends unsolicited e-mails and that they should not open the attachments in the fraudulent messages.
The scam e-mail tells recipients that their Internet use has been monitored by the FBI and that they have accessed illegal Web sites, according to the FBI. The e-mails, which are sent from e-mail addresses including mail@fbi.gov, post@fbi.gov and admin@fbi.gov, then direct recipients to open an attachment and answer questions.
The text of the fake e-mails says: "We have logged your IP-address on more than 30 illegal Websites. Important: Please answer our questions! The list of questions are attached." The messages then include a fake name of an FBI official and the real address and phone number of the agency.
Catherine Milhoan, an FBI spokeswoman, said that recipients of the hoax e-mails began calling the FBI's Internet Crime Complaint Center yesterday to ask if they were legitimate. About 4,000 calls were received by last night, with some callers saying they had already clicked on the attachment. Others were cautious and wanted to check with the FBI before opening the attachment.
An investigation into the incident is continuing.
A similar incident occurred in February, when another fake message purporting to be from the FBI was sent to Internet users, she said. Those messages included similar wording but included the name of a different fake FBI employee.
Recipients of the fake messages are being asked to report them online to the Internet Crime Complaint Center.
