Nicholas Michael Kloster, a resident of Kansas, has been arrested and indicted for launching cyberattacks against three different organizations in 2024. His targets included a fitness club, a nonprofit organization, and his former employer.
Kloster’s motive was strikingly simplistic: to prove his capability as a cybersecurity provider by first compromising systems, thereby demonstrating the very threats he claimed to defend against.
In the fitness club case, Kloster exploited a vulnerability in the surveillance camera system to bypass login restrictions, gaining access to the internal network and membership database. Once inside, he deleted his own photo and reduced his membership fee to just $1 per month.
Following the intrusion, Kloster emailed the gym, informing them of the breach and offering his cybersecurity services to secure their infrastructure and prevent further exploitation.
In the nonprofit case, he used a bootable disk to circumvent authentication protocols, infiltrated the internal network, stole sensitive data, installed a VPN to maintain a backdoor, and modified user passwords to solidify control.
As for his former employer, after being terminated in April 2024, Kloster stole credit card information from the company and used it to purchase various hacking tools. In this instance, he did not offer his services—only sought revenge.
Unfortunately for Kloster, each victim reported the breaches to authorities and attempted remediation, incurring significant financial losses. Through digital traces, including email addresses, law enforcement was able to identify and apprehend him with relative ease.
Kloster is now awaiting trial and, under U.S. federal law, faces up to five years in prison, along with potential substantial restitution payments to the victims. What he likely intended as a self-promotional stunt has instead become a cautionary tale of recklessness and ruin.
