BERLIN, GERMANY - DECEMBER 27: A participant looks at lines of code on a laptop on the first day of the 28th Chaos Communication Congress (28C3) - Behind Enemy Lines computer hacker conference on December 27, 2011 in Berlin, Germany. The Chaos Computer Club is Europe's biggest network of computer hackers and its annual congress draws up to 3,000 participants.

BBC News reported that Hey's review revealed that because of its rising numbers, two-thirds of the emails sent to its users' personal accounts are now containing the malicious content, even if they were excluded for spam. 

Security experts concluded that the developers of spy pixels confirmed that many of the largest brands are currently using the method to track users' email activities. Once they acquired the needed information, they will use them for their marketing tactics. 

On the other hand, the involved companies said that their use of the said technology was stated within their wider privacy policies. If you are using different email services, it is suggested that you read their privacy policies carefully before using their platforms, especially if you are sending sensitive user data. 

What is spy pixel? 

Spy pixel is usually a PNG or GIF file that is located in the email's header, body, or footer. This content is as small as a 1x1 pixel, which makes it harder for users and even tech experts to identify it.

Tech firm Hey claimed that the companies that are using this tracking method include, British Airways, TalkTalk, Vodafone, Tesco, HSBC, Marks & Spencer Sainsbury's, Unilever, and Asos.
