The U.S. government has warned U.S. private financial services of an al Qaeda call for a cyber attack against U.S. online stock trading and banking Web sites beginning Friday, officials said on Thursday.

The officials — a person familiar with the warning and a spokesman for the Department of
Homeland Security — said the Islamic militant group aimed to penetrate and destroy the databases of the U.S. stock market and banking Web sites.

Homeland Security said it had no evidence to corroborate the threat but had issued the warning out of an “abundance of caution.” The department said in a statement that the threat was for all of December.

“There is no information to corroborate this aspirational threat. As a routine matter and out of an abundance of caution, US-CERT issued the situational awareness report to industry stakeholders,” said Homeland Security spokesman Russ Knocke.
