The HostingFest data breach has been confirmed through a ransomware leak announcement naming the Turkey based hosting and IT infrastructure provider. According to the threat actor Nova, internal files containing sensitive customer data, hosting infrastructure documentation, server configurations, administrative credentials, employee records, billing information and corporate communications were stolen from HostingFest. The company provides domain registration, shared hosting, VPS, dedicated servers, e commerce infrastructure, and SEO services to individuals, businesses and enterprise customers across Turkey. The HostingFest data breach is particularly serious because hosting providers maintain deep access to client websites, databases, DNS records, email accounts and virtual server environments. Compromise of these systems can lead to widespread unauthorized access, website defacement, credential theft, database leaks, account hijacking and service disruption for thousands of customers.
Early statements from Nova claim that approximately fourteen gigabytes of internal corporate and customer files were exfiltrated. The breached data may include backups of hosted websites, usernames, hashed passwords, billing records, API keys, support tickets, internal server notes, technical documentation and infrastructure topology diagrams. These files are particularly valuable to attackers because hosting companies act as custodians of customer digital assets. A breach of a single provider can cascade across hundreds of businesses whose websites and services depend on the provider’s security.
Background on HostingFest and the Nature of the Breach
HostingFest is known in Turkey for providing domain registration, high availability hosting, VPS and dedicated server environments. Their services are used by entrepreneurs, small businesses, online retailers, and enterprise customers requiring reliable digital infrastructure. As part of its operations, the company manages DNS records, server provisioning, support escalation, virtualization infrastructure, internal monitoring tools, e commerce integrations and cloud deployment systems. The HostingFest data breach therefore threatens to expose a wide range of client and internal materials that underpin the security of hosted environments.
The company is reportedly licensed under BTK (the Information and Communication Technologies Authority of Turkey), which governs compliance for electronic communication and digital service providers. Companies under BTK oversight must follow strict regulatory controls regarding data handling. The HostingFest data breach may trigger regulatory scrutiny because hosting environments can expose personal data from thousands of customer operated websites.
The attackers stated that HostingFest’s main website is inaccessible due to encryption, indicating potential operational disruption. Ransomware campaigns targeting hosting companies often involve server side encryption of core environments or administrative panels, preventing access to client dashboards or provisioning systems. The full scope of operational damage following the HostingFest data breach is not yet confirmed.
What Attackers Claim to Have Stolen
Nova ransomware claims to have stolen a broad range of sensitive materials. While the group has not yet released the full archive, typical HostingFest system architecture and the nature of hosting operations suggest that the stolen data likely includes:
- Customer account data: usernames, hashed passwords, email addresses and authentication logs
- DNS configuration files and domain control panel data
- Hosting plan details, VPS configurations, and server allocation logs
- MySQL or other database backups containing customer operated website data
- Internal server credentials, administrative keys, SSH access files and configuration templates
- Support ticket conversations, client identity verification documents and chat logs
- Billing information including invoices, transaction logs and payment confirmations
- Employee HR files, internal contact lists, shift schedules and organizational charts
- Server infrastructure documentation, network diagrams and security policy files
- Email hosting data including mailbox records or message metadata
Each of these categories contains data that cybercriminals can weaponize for account takeovers, credential stuffing, extortion, exploitation of hosted systems or resale on dark web marketplaces.
Why the HostingFest Data Breach Is a High Risk Event
The HostingFest data breach is especially severe because the security of a hosting provider affects all downstream clients. Key risk factors include:
- Access to website backups means attackers may gain visibility into proprietary code, customer information and business operations
- DNS record exposure can allow attackers to hijack domains, redirect traffic or spoof websites
- Email accounts hosted by the provider may be compromised, enabling phishing and internal impersonation
- Server credentials may enable unauthorized control of virtual machines
- Database leaks may expose sensitive information belonging to customers of HostingFest clients
Hosting providers operate as infrastructure level custodians. Compromising them is significantly more damaging than a standalone website breach because one attack can ripple across hundreds or thousands of businesses.
Impact on Client Websites and Digital Infrastructure
Depending on the nature of the files stolen, the HostingFest data breach may cause widespread impact across customer hosted environments. Possible consequences include:
- Website takedowns or ransomware installs on compromised client servers
- Administrative panel hijacking leading to unauthorized DNS or hosting changes
- Database leaks exposing user information from customer websites
- Interception of email traffic or misuse of email accounts hosted on the provider’s servers
- SEO poisoning attacks using compromised hosting accounts
- Malware injection into client websites
Hosting providers are often targeted because attackers know that a single breach can open thousands of additional attack vectors.
Internal Business and Regulatory Risks
The HostingFest data breach may also expose the company to significant internal and regulatory consequences. These include:
- BTK regulatory investigation for failure to protect customer data
- Potential fines if personal data obligations were violated
- Loss of customer trust leading to churn and reputational damage
- Increased operational cost associated with remediation and forensic analysis
- Legal risks from customers whose data may have been exposed
Companies providing hosting services in Turkey operate under a regulated framework that mandates protection of personal and infrastructure data. The HostingFest data breach may therefore trigger mandatory reporting obligations.
Threat Actor Profile: Nova Ransomware
Nova ransomware is a financially motivated threat actor known for:
- Encrypting servers and administrative systems to halt operations
- Exfiltrating large volumes of internal corporate data before ransom negotiation
- Threatening to publish data if payment is not made
- Targeting technology, cloud service and hosting providers specifically
- Using countdown timers to pressure victims into payment
Nova’s operations often involve exploiting unpatched vulnerabilities in internet facing systems or stealing credentials through phishing or keylogging. The group tends to attack infrastructure providers because they offer high leverage and high ransom potential.
Financial and Customer Data Exposure
The HostingFest data breach may involve financial documents such as:
- Customer invoices, transaction histories and subscription logs
- Internal revenue summaries and expense reports
- Merchant payment gateway configurations
- Tax documentation or account reconciliation files
Billing data can be used for fraud, unauthorized transactions or spear phishing. Attackers frequently use leaked financial data to craft highly convincing social engineering campaigns.
Risks to Hosted E Commerce Clients
HostingFest also supports businesses operating e commerce sites. The HostingFest data breach may expose:
- Order databases containing customer addresses and purchase histories
- Emails sent to customers via hosted mail systems
- Merchant configurations for payment processing tools
- Stored API keys used for shipping, logistics or payment services
If attackers gain access to stored API keys, they may manipulate transactions or impersonate customers and merchants.
Recommended Mitigation Steps for Customers
For Website Owners
- Immediately rotate hosting account passwords, database passwords and SSH keys
- Review website files for unauthorized modifications
- Change credentials for any admin panels accessed through the hosting environment
- Audit DNS records for unauthorized edits
- Update all CMS software, plugins and themes to reduce follow on compromise
For E Commerce Store Owners
- Rotate API keys for payment processors, shipping services and email providers
- Check server logs for suspicious access patterns
- Inspect order databases for unauthorized queries
- Inform customers of potential exposure if applicable
For Individuals Using Hosted Email
- Change passwords and enable multi factor authentication on all email accounts
- Monitor for unusual login attempts
- Beware of phishing emails referencing HostingFest or service disruptions
Recommended Actions for HostingFest
HostingFest must take several urgent steps to minimize damage from the breach:
- Isolate compromised servers and rebuild critical infrastructure
- Conduct a complete forensic investigation with external specialists
- Notify affected customers and provide clarity about exposed data
- Rotate internal credentials, SSH keys, panel access and administrative tools
- Implement system hardening against similar intrusion pathways
- Engage with BTK to meet regulatory obligations
Hosting companies must also ensure that stored backups have not been tampered with before restoration.
Long Term Implications of the HostingFest Data Breach
The HostingFest data breach may create lasting consequences for both the provider and its customers:
- Reputational loss may push customers to migrate to alternative hosting providers
- Future security of client websites may be compromised if attackers retain stolen data
- Regulatory consequences may require HostingFest to overhaul infrastructure security
- Small businesses dependent on HostingFest may face operational downtime
- Attackers may reuse stolen data to target customers for months or years
Hosting providers often hold decades worth of customer files. The exposure of even fourteen gigabytes of internal documents can reveal long term infrastructure details that attackers may weaponize.
Broader Implications for Hosting Providers
The HostingFest data breach highlights several broader risks to the hosting industry:
- Hosting companies are prime targets due to concentration of sensitive client data
- Older hosting architectures with legacy systems are frequent attack vectors
- Cross contamination between client environments is possible if security is insufficient
- Data exfiltration can occur even if ransomware encryption is mitigated
- Providers must implement zero trust, segmentation and continuous monitoring
Many hosting providers underestimate threat actor sophistication. Nova and similar groups actively target infrastructure level service providers because of the large leverage and potential financial gain.
