In the next step of the video, we will analyze in more details the incident and the impact it had on LaBella Associates and their customers.

On 12 November 2025, LaBella Associates disclosed data breach and ransomware attack issues under the banner "LaBella Associates Data Breach (2025)".

A major architecture and engineering firm, LaBella Associates, experienced a ransomware attack by the RHYSIDA group, leading to the potential exposure of sensitive personal data of current and former employees.

The disruption is felt across the environment, affecting internal network, and exposing personally identifiable information (PII), names and addresses, with nearly 6,712 records at risk.

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like secured network, and stakeholders are being briefed through disclosure to Maine and Massachusetts Attorneys General (2025-11-12) and mail notifications to impacted individuals (2025-11-12).

The case underscores how completed (2025-10-13), and recommending next steps like Enroll in offered TransUnion Cybersout credit monitoring and fraud assistance services and Monitor credit reports and financial accounts for suspicious activity, with advisories going out to stakeholders covering Mail notifications sent to impacted individuals (2025-11-12) and Offer of free TransUnion Cybersout credit monitoring and fraud assistance.

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.

Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Exploit Public-Facing Application (T1190) with moderate to high confidence (70%), supported by evidence indicating ransomware attack by the RHYSIDA group detected after suspicious network activity and Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating internal network compromised; no explicit vector but common for ransomware. Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate to high confidence (75%), supported by evidence indicating internal network breach with PII/financial data exfiltration suggests lateral movement. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (95%), supported by evidence indicating pII such as names, SSNs, financial account info of 6,712 individuals exfiltrated. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol: Exfiltration to Cloud Storage (T1048.003) with moderate to high confidence (85%), supported by evidence indicating threatened to publish stolen data on dark web via Tor network and Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating rHYSIDA group known for C2-based exfiltration before ransomware deployment. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating ransomware attack by RHYSIDA (strain confirmed) and Data Destruction (T1485) with moderate to high confidence (70%), supported by evidence indicating threatened dark web leak implies potential data destruction if ransom unpaid. Under the Defense Evasion tactic, the analysis identified Indicator Removal: File Deletion (T1070.004) with moderate to high confidence (70%), supported by evidence indicating secured network post-breach suggests attacker cleanup or persistence mechanisms and Impair Defenses: Disable/Modify Tools (T1562.001) with moderate confidence (65%), supported by evidence indicating suspicious network activity detected late (March 2025) implies evasion of initial defenses. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
