Reminder: be careful opening invoices on the 21st March
On March 4th we spotted a large number of unusual emails being blocked by our Linux Mail Security product. The emails all contained the same PDF attachment (MD5: 97b720519aefa00da58026f03d818251) but were being sent from many different source addresses. The emails were written in German and most were sent from German IP addresses. Below is a map showing the distribution of addresses: The computer names referenced in the mail headers were often of the form Andreas-PC or Kerstin-Laptop (the names have been changed to protect the innocent) suggesting that they had been sent from German home computers.
