Pro-Tuff | Decals Listed by Global Secret Group Ransomware Group: What Was Exposed & What To Do

Pro-Tuff Decals, a small business-services firm based in Crystal Lake, United States, has been listed by the ransomware group known as Global Secret Group. The listing, reported on July 26, 2026, claims that internal files were exfiltrated in a ransomware attack. Public detail on the incident remains limited: the number of people affected is unknown, and independent confirmation of the group’s claims has not been provided in available records.

What is documented so far centers on the group’s assertion that a substantial volume of material—described as 412 GB comprising 589,623 files across 40,081 folders—was taken. For customers, partners, and employees of a firm that produces custom decals and related business services, any confirmed exposure of internal files raises practical questions about what information may now be outside the organization’s control.

Breaking down the breach

According to the reported listing, Global Secret Group claims responsibility for a ransomware attack against Pro-Tuff Decals in which internal files were exfiltrated. The report associates the victim with the website protuffdecals.com, places the organization in Crystal Lake in the United States, and notes an approximate revenue of $9.6 million and a workforce of roughly 10–20 employees. The industry classification given is business services.

The listing further states that the exfiltrated material totaled 412 GB, broken down as 589,623 files in 40,081 folders. No public timeline of the intrusion, no description of the initial access method, and no confirmation of whether systems were encrypted or merely copied have been included in the available facts. The number of individuals whose information may be involved is recorded as unknown. Beyond the group’s leak-site claim and these high-level figures, specifics of the attack remain undisclosed.

Who is Global Secret Group?

Global Secret Group is presented in public reporting as a ransomware operation that lists victim organizations on leak sites and claims to have stolen data. Like other groups in this category, such actors typically gain access to networks, move laterally, exfiltrate files, and then threaten publication or sale of the material if a ransom is not paid. Their public postings often include volume estimates and file counts as pressure tactics.

Well-documented patterns among ransomware groups include opportunistic targeting of small and mid-sized businesses, use of double-extortion (encryption plus data theft), and periodic dumping of sample files to demonstrate access. For this specific incident, the only attribution in the record is the group’s own listing of Pro-Tuff Decals. That listing should be treated as an unverified claim unless and until independent confirmation appears. No statements by the group beyond the fact of the listing and the claimed data volume are provided in the available facts.

Who is Pro-Tuff Decals?

Pro-Tuff Decals operates in the business-services sector, producing custom decals and related products for commercial and organizational customers. Public business data associated with the listing describe a company of 10–20 employees, roughly $9.6 million in revenue, and a base in Crystal Lake, United States, with an online presence at protuffdecals.com.

Organizations of this type commonly hold customer order records, design files, shipping and contact details, invoices, employee information, and internal operational documents. A breach involving internal files is consequential because even a modestly sized firm can store years of correspondence, payment-related data, and proprietary artwork or client specifications. Disruption or exposure can affect both day-to-day operations and the trust of the businesses and individuals who rely on the company.

What data was at risk

The facts name the exposed material only as “internal files exfiltrated in a ransomware attack,” with the claimed volume given as 412 GB (589,623 files, 40,081 folders). No further breakdown—such as whether customer databases, financial records, employee data, or design assets were included—has been disclosed.

Companies in custom manufacturing and business services typically maintain customer contact and order information, payment and invoicing records, employee personnel files, vendor contracts, and digital design or production files. It is reasonable to expect that some combination of these categories could exist inside an internal file store of that size. However, the exact contents of the claimed exfiltration remain unconfirmed. No specific data types beyond the general label “internal files” should be treated as established fact.

Why it matters

For individuals and organizations that have done business with Pro-Tuff Decals, the primary risk is that personal or commercial information contained in internal files could be misused if the group’s claims are accurate and the data is later published or sold. That can include unwanted contact, targeted phishing that references real orders or relationships, or exposure of business-sensitive details. Employees face similar concerns if personnel or payroll-related documents were among the files.

For the company itself, a ransomware incident can interrupt production, damage customer confidence, and create legal or contractual notification obligations depending on what was taken and which jurisdictions apply. Because the number of people affected is unknown and the precise data types are undisclosed, the full scope of harm cannot yet be measured. The concrete takeaway is that any party who has shared information with the firm should treat the possibility of exposure seriously until clearer inventories emerge.

If your data was in this breach

If you have been a customer, partner, or employee of Pro-Tuff Decals, begin by monitoring accounts and communications for unusual activity, especially messages that reference past orders or internal details. Consider changing passwords on related accounts and enabling multi-factor authentication where available. Review financial and credit activity if payment information could have been stored. Keep records of any suspicious contact.

You can also run a free exposure scan of your email address to check whether your information has already surfaced in known breach data sets. Staying alert to official notices from the company, if any are issued, will help you decide on further steps as more confirmed detail becomes available.
