SIZE DOESN'T MATTER

摘要

Two years ago, the vice president of human relations at Texas Trust Credit Union (TTCU), a 60,000-member business in the Dallas area, received an unexpected email from a law firm. Attached was a complaint letter.rnSensing something may have been amiss and having been trained to be on the lookout for questionable messages, the employee right-clicked on the attachment, where he was able to determine that the document was no complaint letter at all - it actually was a malware-laden ZIP file disguised to look like a PDF. "What the scary part of it was, our anti-virus software didn't detect anything malicious about the threat," says David Naylor, 29, TTCU's IT security coordinator. "And our email filter at the time didn't have any concept of how to handle it."
