glenwoodnyc.com Listed by dAn0n Ransomware Group

On May 8, 2024, property management firm Glenwood Management appeared on the leak site operated by the dAn0n ransomware group. The New York-based company, which manages luxury apartment buildings across the city, had 1.78 TB of internal files taken during a ransomware incident. The disclosure indicates that customer and operational records were exfiltrated, though the exact number of affected individuals remains unknown.

Details in the Leak Listing

The dAn0n leak site lists glenwoodnyc.com and states that 1.78 TB of internal files were exfiltrated in a ransomware attack. The posting does not specify the precise data types beyond “internal files,” nor does it publish sample documents or name particular categories such as tenant Social Security numbers or banking details. It does state the data was stolen rather than simply encrypted, consistent with the double-extortion model used by this group. The listing carries no public ransom demand figure or payment deadline, which is typical when negotiations remain active or have broken down.

Why This Matters for You and Your Family

If you live in or have applied to any Glenwood-managed building, your personal information may now sit in an attacker-controlled archive. Property management records routinely contain full names, dates of birth, current and previous addresses, phone numbers, email accounts, employer details, and copies of identification documents. Even without exact record counts, the volume—1.78 TB—suggests thousands of current and former tenants are potentially exposed. For families, this can include information on spouses, children listed as dependents, or guarantors on lease applications. Once such data leaves the company’s control, it circulates among initial buyers and downstream fraud networks, increasing the chance of identity theft, tax fraud, or targeted phishing years after the breach.

Doxxing and Identity-Chain Risks

Leaked rental files create long identity chains. An email address tied to a Glenwood lease can be correlated with gaming usernames, social-media handles, and school records. Attackers then map these connections to build a complete profile. Credential leaks like this one cascade into account takeovers, especially when the same password protects streaming services, email, or your children’s Roblox, Fortnite, or Minecraft accounts. A single address or phone number from the leak can link a parent’s identity to a child’s gaming profile, exposing the entire household to doxxing, swatting, or social-engineering attacks. The longer the data remains unmonitored, the more links attackers can forge.

dAn0n’s Known Track Record

Public reporting attributes the dAn0n ransomware group’s first notable activity to late 2022. The group has since targeted mid-sized businesses in healthcare, education, and real estate, often focusing on organizations that handle sensitive resident or patient data. Their typical playbook begins with phishing or exploitation of remote desktop services for initial access, followed by lateral movement to file servers, exfiltration of documents, and then dual extortion: threatening both data publication and decryption refusal. The Glenwood listing follows this pattern exactly. While dAn0n is not among the largest ransomware operations, its leak site remains active and its operators consistently follow through on publishing stolen archives when payments are not received.

What to do

• Run a DoxxScan to map every link between your email, phone, addresses from the Glenwood lease, and any associated online handles.
• Rotate passwords used on glenwoodnyc.com or any related tenant portal anywhere those credentials are reused, and switch to 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours instead of months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts that can chain back to the same leaked address or phone number.
• Let remediation specialists handle ongoing takedown requests for any data-broker listings that surface from this or connected breaches.
