I originally wrote about spear phishing this past summer. In case you missed it these attacks are more targeted and designed to look like they are coming from a trustworthy source such as someone in your enterprise. It seems people will share their passwords fairly willingly via e-mail if the trust the source.

Here is a more recent article on spear phishing and how hackers are targeting credit union executives by sending them a link to a site that contains a Trojan horse program. Some users had recently updated their virus definitions and were safe from the attack. It is unclear how many people were duped by this fraudulent e-mail.

Thankfully the phishers in this case had bad grammar and some recipients of the e-mail become immediately suspicious of the scheme.
