Criminals never stop coming up with new ways to mess you up via the Internet. The Most Dangerous E-mails Part 2! As always, remember there are variations on each of these cons, so be wary of anything even resembling what you read in the following.

Airline Tickets

If you're not flying anywhere, be on the lookout for any ticket messages from airlines, including major ones like JetBlue, Frontier Airlines, and US Airways. E-mails are going out saying that your credit card has been used to purchase a ticket contained in an attached Zip file. If you open it the file, it downloads malware that can be used to steal your personal information. Should you receive an e-mail like this, delete it immediately and contact authorities if you receive it or have already opened it.

Search Engine Optimization Offers

Whether it's business or personal, having your own Web site puts you at risk from scammers. Currently, companies offering better search results for your site are offering their services for a fee, although there's no real company. Like any unsolicited e-mails, don't respond to them without looking into the business first and don't give away anything personal before you find out if it's legit. In this case, the lack of company information and bizarre e-mail addresses are the most telling signs that it's phony.

Holiday E-mails

Major holidays means it's time to be wary of any greeting cards from unknown senders. Many of these e-mails provide a link to see a message or download some sort of file, but really all you're doing is downloading the Storm Worm. We warned you about it last year at Valentine's Day, and be sure to keep a lookout for the creepy above-pictured skeleton e-card with Halloween right around the corner.

Time Warner Cable Threat

If you're a customer of Time Warner (which is the parent company of AOL and Switched.com), outages might not be your only problem. Clients in San Antonio, Texas, all of whom used the Road Runner Internet service, recently received e-mails sent with the company's name and logo asking them to provide account information or they would lose service. Time Warner says that people receiving these messages should delete them and contact the company.

Wall Street Woes

While there haven't been any confirmed cases yet, the creators of CertifiedMail issued a warning that spammers will most likely try to use the current economic crisis for phishing (a.k.a., online scamming) purposes. Just as with the hurricanes, the security experts at CertifiedMail believe criminals will capitalize on fear and the high profile nature of the story, so be warned.

Obama Sex Scandal

Yes, fake news is all the rage for scammers and they've taken to politics for their latest sensational stories. In one of the more recent versions of the threat, an e-mail purports to have a video of Barack Obama having sex with a Ukrainian woman. Of course, you click on the video and it's malware. As we've said before, please stick to legitimate news sites.
