Homeland Security officials are warning that some e-mails purporting to be from the department's intelligence division were fake and contained malicious software.
The e-mails actually originated from Internet addresses in Latvia and Russia, according to a brief alert from the Homeland Security Department's counterintelligence unit the department said, according to a document obtained by The Associated Press.
The Homeland Security Department has sent the warning to the Defense Department and state and local officials after receiving complaints about the e-mails since June. The e-mails were made to look as if they had actual text from a department intelligence assessment. They included links embedded with malware known for stealing banking data protected passwords.
