Did You Receive A Data Breach Notice From WK Kellogg?

If so, your sensitive personal identifiable information may have been stolen!

WK Kellogg is the well-known food brand which makes packaged breakfast cereals. They are headquartered in Battle Creek, Michigan, but have locations in several other states as well as Canada and Mexico.  On April 4, 2025, WK Kellogg sent out notice letters alerting recipients of a data breach which exposed private employee information.  The breach occurred through a third party vendor the company uses, called Cleo. Some of Cleo’s servers were hacked in December of 2024, which impacted WK Kellogg data as well.  The information accessed may include WK Kellogg employee names and Social Security numbers.

Data breaches are serious matters that can cause long term damage. Hackers break into networks so that they can steal your personal information to sell it on the dark web, commit identity theft, financial theft or other frauds.
