Storm worm spam nearly doubles in volume

Account confirmation scam is designed to grow botnets.

Account confirmation spam is the latest spammer trick, asking recipients to confirm their account information with a bogus organization by logging into a Web site that is infected with the Storm Trojan malware. This latest technique is catching on: Account confirmation spam has grown in volume from 18 percent of all spam on Tuesday to 35 percent Wednesday.

These e-mails, spotted by security vendor Marshal, tell recipients they must visit a Web site and use the included temporary login details to set a permanent login and confirm their account. Unlike most spam, the link to the Web site is not an embedded URL but an IP address.

If followed, the link brings recipients to a Web site that asks them to install a 'secure login applet,' which in fact is the Storm Trojan, says Ed Rowley, an engineer at Marshal.

This spam blast gives a new cybercrime role to Storm Trojan, which secretly infects PCs and turns them into members of a botnet that attacks other PCs. The Trojan was first detected in January and has since been the payload of spam blasts ranging from fake headlines to greeting-card notifications.

With spam levels threatening to break records this month, spammers are coming up with new and different scams on a near-daily basis. Last week saw levels of PDF spam that pump penny stocks hit an all-time high. On that scam's heels is this completely different type of spam designed to grow botnets.

"The key item of interest is how quickly the criminal gangs are changing their techniques," says Rowley. "Over the last few weeks we have seen them experimenting with spam and using all sorts of different attachments. This time they are trying different techniques to get users to infect their machines and become part of the problem."

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
