Chemical Maker, Seydel Companies, Suffers Cyberattack
Pendergrass, Michigan-based chemical maker The Seydel Companies, Inc. suffered a cyberattack this past spring that led threat actors to make off with personally identifiable information of victims.
“On April 26, 2025, we identified unusual activity indicating potential unauthorized access to our network,” the company said in a letter to victims of the hack. “Upon learning of the incident, Seydel immediately took steps to secure our systems and commenced a prompt and thorough investigation assisted by external cybersecurity professionals experienced in handling these types of situations to assist us in determining the full extent of the incident and scope of any data impacted.”
The company said its investigation found an unauthorized actor accessed its systems on April 26, and, as a result, possibly viewed and/or obtained certain files.
