High volume spam is a seasonal business. Over many years spammers discovered best times of the year to ensure the highest possible response rate to their messages. It turns out that the period between Black Friday and the last day for Christmas shipping is one of the best times to reach an intended audience with malicious messages. It is a time of the year when we all do a lot of online shopping and are expecting confirmation emails from retailers we purchased goods from and tracking messages telling us where our packages are.
Here at Barracuda, we noticed this trend happening in the weeks leading up to Christmas. There was a large increase in fake UPS and FedEx messages and fake confirmation emails from your favorite e-tailers during this time.
