Be on your toes for scam emails during the Holidays!

If you receive an email this holiday season asking you to “confirm” an online e-commerce order or package shipment, please resist the urge to click the included link or attachment: Malware purveyors and spammers are blasting these missives by the millions each day in a bid to trick people into giving up control over their computers and identities.

Home Depot

An “order confirmation” malware email blasted out by the Asprox spam botnet recently.
Seasonal scams like these are a perennial scourge of the holidays, mainly because the methods they employ are reliably successful. Crooks understand that it’s easier to catch would-be victims off-guard during the holidays. This goes even for people who generally know better than to click on links and attachments in emails that spoof trusted brands and retailers, because this is a time of year when many people are intensely focused on making sure their online orders arrive before Dec. 25.

Walmart

This Asprox malware email poses as a notice about a wayward package from a WalMart order.
According to Malcovery, a company that closely tracks email-based malware attacks, these phony “order confirmation” spam campaigns began around Thanksgiving, and use both booby-trapped links and attached files in a bid to infect recipients’ Windows PCs with the malware that powers the Asprox spam botnet.

Asprox is a nasty Trojan that harvests email credentials and other passwords from infected machines, turns the host into a zombie for relaying junk email (such as the pharmaceutical spam), and perpetuates additional Asprox malware attacks. Asprox also deploys a scanning module that forces hacked PCs to scan websites for vulnerabilities that can be used to hack the sites and foist malware on visitors to that site. For an exhaustive and fairly recent analysis of Asprox, see this writeup (PDF) from Trend Micro.

Target

Target is among the many brands being spoofed by Asprox this holiday season.
Malcovery notes that the Asprox spam emails use a variety of subject lines, including “Acknowledgment of Order,” “Order Confirmation,” “Order Status,” “Thank you for buying from [insert merchant name here]”, and a “Thank you for your order.”
If you receive an email from a recognized brand that references an issue with an online or in-store order and you think it might be legitimate, do not click the embedded links or attachment. Instead, open up a Web browser and visit the merchant site in question. Generally speaking, legitimate communications about order issues will reference an order number and/or some other data points specific to the transaction — information that can be used to look up the order status at the merchant’s Web site. I know I’m probably preaching to the choir for the loyal readers of this site, but I’m sure most of you have friends and relatives who could use a reminder about all of this. Please feel free to forward them a link to this story.
