Reported by MAINE AG, NEW HAMPSHIRE AG filings
New England Development experienced a ransomware attack on October 2, 2020, discovered on October 3, 2020. The incident affected 4,526 individuals, including 32 Maine residents. Personal information compromised included names and Social Security Numbers. The entity provided written notification on November 11, 2020, and offered 24 months of credit monitoring services through Kroll.
Affected (this filing): 4,526
New England Development (NED), a real estate development and management company, notified the New Hampshire Attorney General on November 6, 2020, of a ransomware attack discovered on October 3, 2020. The attack involved the NetWalker ransomware group. Approximately 115 New Hampshire residents (current/former employees and contractors) were potentially affected. While the attacker was on the network for ~10 hours and exfiltrated 16 files, NED determined these did not contain PII. However, in an abundance of caution, NED is notifying individuals whose data (including SSNs) may have been on the network. NED engaged Coretelligent and Arete Advisors for forensic investigation, restored systems from backups, reported to the FBI, and offers 2 years of credit monitoring.
Affected (this filing): 115

About this clustering
DisclosureLens links filings into incidents through layered matchers: deterministic rules (same source document, multistate filings of one breach, tight-window same-victim pairs), a weighted-similarity scorer for cross-source candidates, and an operator review queue for everything uncertain. Each link records its own method and confidence — shown per filing in the timeline below. The system defaults to NOT merging when uncertain, because a false merge (collapsing two unrelated breaches) is more harmful than a false split (showing related filings separately); uncertain pairs route to human review instead of auto-merging. Filing summaries shown in the timeline are AI-generated extracts — verify each against its linked source.
