When did the Intelbroker data breach happen?
The breach was first detected in early 2025 during a coordinated investigation by law enforcement and cybersecurity teams. Detailed timelines indicate that the intrusion began months earlier, with the exfiltration of sensitive data escalating in early January 2025.
Who hacked Intelbroker?
The breach has been attributed to an individual known as "Intelbroker," a serial cybercriminal and hacker allegedly responsible for $25 million in damages. Intelbroker has been associated with sophisticated ransomware campaigns and data leaks targeting businesses and institutions.
How did the Intelbroker breach happen?
The breach was executed through a combination of phishing attacks and exploitation of unpatched vulnerabilities within affected systems. Intelbroker leveraged compromised credentials to gain access and employed advanced persistence techniques to remain undetected for an extended period.
Intelbroker data breach timeline
Late 2024: Initial compromise via phishing campaign.
January 2025: Large-scale exfiltration of sensitive data begins.
March 2025: Public disclosure of the breach by affected organizations.
Mid-2025: Law enforcement and forensic investigations progress.
Technical details
Intelbroker exploited vulnerabilities in unpatched software to permeate network defenses. Persistence mechanisms included the use of custom malware and lateral movement across systems to access high-value data. The stolen data was then either sold on dark web marketplaces or leaked to increase pressure on the victims.
Indicators of Compromise (IoCs)
IP addresses associated with command-and-control servers.
Hashes of known malware strains used in the attacks.
Domains linked to data exfiltration activities.
Forensic and incident investigation
Third-party cybersecurity firms and law enforcement collaborated to identify the attack vectors and mitigate ongoing risks. Post-breach audits highlighted the need for improved patch management and enhanced phishing awareness training among employees.
What data was compromised in the Intelbroker breach?
The breach resulted in the exposure of PII such as names, email addresses, and Social Security numbers. Additionally, corporate financial records and confidential business documents were compromised. The data was not encrypted before exfiltration, exacerbating its impact on victims.
How many people were affected by the Intelbroker data breach?
Exact figures remain undisclosed, but early estimates suggest that millions of individuals and numerous organizations were impacted by the breach.
