On December 20, 2025, the Play ransomware group added Security ONE Alarm Systems to its leak site, claiming that internal files had been exfiltrated from the Canadian company during a ransomware attack.

What Public Reporting Shows
Public reporting indicates the Canadian security alarm provider was listed on the Play ransomware leak site on that date. The group claims to have stolen internal files, though the exact number of people affected remains unknown. Available reporting describes the exposed material as internal company documents rather than a specific customer database. No evidence has surfaced showing that customer names, addresses, or payment details were published on the leak site itself.
Why This Matters for You and Your Family
When a home security company suffers a breach, the data involved often includes names, addresses, phone numbers, email accounts, and details about the alarm systems installed at residential properties. These records can reveal exactly where you live and how your home is protected. For families, this creates a direct privacy and safety risk. Criminals who obtain such information can target you with phishing texts, spoofed calls pretending to be your alarm provider, or even physical surveillance. If your children use family email addresses or shared phone numbers for online gaming, those same credentials can link back to your household and widen the exposure.
The Doxxing and Identity-Chain Risks
Ransomware leaks rarely stop at one company. Once internal files containing employee or customer contact information appear on a dark-web forum, other attackers scrape them and combine them with data from previous breaches. This creates an identity chain: an email address from the alarm company can be matched to a username on a gaming platform, which then links to a social-media account, revealing your full name, children’s names, and home address. Credential leaks like this one cascade into account takeovers and doxxing chains. A single exposed work or home email can unlock multiple services if the same password was reused, turning one corporate breach into long-term personal exposure for you and your family.
