Online shoppers beware; big retail companies the subject of distributed malware and phishing attacks

Print Friendly, PDF & Email

Aside from being retail juggernauts, companies like Best Buy, Walmart, and Costco have another big thing in common this holiday season. These brands are among the highest names being used in malware and phishing campaigns worldwide.

Over the past couple of weeks, Barracuda Labs has continued to see an uptick in the amount and frequency (millions of emails) of spamming and phishing emails, in attempt to prey on online shoppers.

Spammers have attempted to phish for credentials to these popular sites by sending emails that include virus attachments disguised as receipts. This seems like a reasonable plan, hoping to lure unsuspecting holiday shoppers into printing out the receipts in order to pick up their products.

While we expect an increase as Christmas approaches, we urge everyone placing orders online to protect themselves by adhering to a few simple rules:

  • Track your orders on the same site you placed it.
  • Do not download any attachments. FedEx and UPS will never ask you to download or print any document to have your package delivered.
  • If it's too good to be to true it, it probably is. Stick to the sites that have a good reputation — if you have never heard of the site and it promises items at heavily discounted prices, you probably want to stay clear from shopping there.

Customers running the Barracuda Spam Firewall and Barracuda Email Security Service with the latest security definitions are protected from this attack.
