- Ryan Goldberg and Kevin Martin received four-year federal prison sentences on April 30, 2026 for using BlackCat/ALPHV ransomware to extort organizations they were supposed to protect.
- Co-conspirator Angelo Martino secretly shared victims' insurance policy limits with ransomware operators — a severe insider threat that maximized ransom demands against his own clients.
- The trio collectively extorted over $75 million from at least four companies and a nonprofit, with one victim paying approximately $1.2 million in Bitcoin.
- This case exposes a critical gap in cybersecurity vendor oversight and should prompt every organization to re-examine who accesses sensitive financial data during an incident response engagement.
What Happened
On April 30, 2026, two cybersecurity industry insiders were handed four-year federal prison sentences for orchestrating ransomware attacks against the very organizations they were hired to protect. Ryan Goldberg, 40, a former incident response manager at cybersecurity firm Sygnia based in Georgia, and Kevin Martin, 36, a Texas-based employee of cryptocurrency transaction firm DigitalMint, were convicted of conspiracy to commit extortion using the ALPHV/BlackCat ransomware platform between April and December 2023.
A third co-conspirator, Angelo Martino, 41, a senior ransomware negotiator at DigitalMint in Florida, pleaded guilty on April 20, 2026 and is scheduled for sentencing on July 9, 2026. Authorities seized $10 million of his assets, including digital currency, vehicles, a food truck, and a luxury fishing boat — a stark illustration of how much personal enrichment this scheme generated.
Together, the three men extorted over $75 million from at least four companies and a nonprofit. In one documented case, a single victim paid approximately $1.2 million in Bitcoin, which the defendants then split and laundered to conceal the proceeds from investigators.
The most damaging betrayal came from Martino, who abused his role as a ransomware negotiator by secretly sharing victims' insurance policy limits with BlackCat operators — allowing attackers to calibrate their demands to the maximum a victim could pay. This is a textbook insider threat (when a trusted employee intentionally harms the organization they work for) that demonstrates how dangerous unchecked access to sensitive financial data can be during a crisis. The entire incident response process is built on trust, and this case shattered it.

Why It Matters for Your Organization's Security
This case is more than a criminal indictment — it is a stress test of the entire ransomware incident response ecosystem, and its implications for your data protection strategy are immediate and serious.
ALPHV/BlackCat, at its peak, was the second most prolific Ransomware-as-a-Service (RaaS) variant (a criminal business model where ransomware developers license their tools to "affiliates" who conduct attacks independently) in the world. As of September 2023, it had collected over $300 million in ransoms from more than 1,000 victims worldwide. Approximately 75% of its known victim organizations were located in the United States, with roughly 250 victims identified internationally. The FBI's December 2023 disruption operation — conducted alongside Europol and agencies from Germany, Denmark, Australia, Spain, the UK, Austria, and Switzerland — produced a decryption tool distributed to over 500 BlackCat victims, but could not undo the financial and reputational damage already inflicted.
The RaaS affiliate model is particularly dangerous because it scales criminal operations rapidly and attracts people with legitimate industry expertise. Affiliates like Goldberg, Martin, and Martino retained 80% of every ransom paid, with 20% going to the core BlackCat/ALPHV operators. That financial incentive — keeping four out of every five dollars extorted — proved powerful enough to corrupt credentialed professionals. Strong cybersecurity best practices have always included rigorous vendor vetting, but this case proves that certifications and background checks alone are insufficient safeguards when financial temptation is this extreme.
The Martino angle is especially alarming from a data protection standpoint. When a negotiator discloses a victim's insurance policy ceiling to the attacker, they don't just harm one client — they undermine the entire trust framework that makes ransomware recovery possible. "These defendants exploited specialized cybersecurity knowledge not to protect victims, but to extort them," said U.S. Attorney Jason A. Reding Quiñones of the Southern District of Florida. "They used ransomware attacks — the very threats they were paid to defend against — as weapons for personal profit."
Industry commentators have noted that this case raises difficult questions about accountability in the incident response and ransomware negotiation industry. Unlike law firms or medical practices, cybersecurity consultancies and negotiation firms face limited regulatory scrutiny, few mandated disclosure requirements, and even fewer audit trails to detect conflicts of interest in real time.
For small and mid-sized businesses, the practical lesson is clear: incident response is not a black box. You need to know who is accessing your organization's financial and insurance information during a crisis, what data they are sharing, and with whom. Effective threat intelligence (the practice of gathering and analyzing information about current and emerging cyber threats to inform defensive decisions) must include not just external attackers, but the vendors and contractors operating inside your perimeter during an active incident. Elevating security awareness around third-party risk is no longer optional — it is a core leadership responsibility.
The AI Angle
Building on the need for stronger vendor oversight, artificial intelligence is increasingly becoming a critical layer in detecting exactly the kind of insider threat this case exposed — before it causes irreversible harm.
AI-powered security platforms like Microsoft Sentinel and Darktrace use behavioral analytics (software that learns what "normal" activity looks like for each user and flags deviations in real time) to detect anomalies the moment they occur. Had victim organizations been running such tools during the 2023 attack window, unusual data transfers — such as a negotiator exporting insurance policy documents to an unauthorized external party — might have triggered an immediate alert rather than a months-long investigation after the fact.
Modern threat intelligence platforms powered by machine learning can also flag when a contractor's access patterns deviate from their expected role, and enforce least-privilege access controls (limiting users to only the data they absolutely need for their specific job function). This is especially valuable during high-stress incident response scenarios, when security teams are distracted and oversight can slip. Implementing AI-driven monitoring is not just a cybersecurity best practice — it is a structural defense against the insider threats that no background check can reliably prevent. Good data protection means assuming that even trusted partners can go rogue.
What Should You Do? 3 Action Steps
Do not wait for a crisis to evaluate who you are trusting with your most sensitive financial data. Review existing contracts with incident response and ransomware negotiation vendors and ensure they explicitly prohibit the sharing of insurance policy limits, coverage details, or internal financial data with any third party — including law enforcement liaisons, unless legally required. Require vendors to provide detailed access logs for every engagement involving your data. Cybersecurity best practices for vendor management should include annual reviews, not just onboarding due diligence. Ask vendors directly: who else sees the information we share with you, and how is that access logged?
During any active security incident, apply the same scrutiny to external consultants that you would apply to unknown users on your network. Deploy User and Entity Behavior Analytics (UEBA) tools — software that tracks what data each user accesses, copies, or transmits — to monitor all activity during response engagements. This creates a real-time audit trail that can surface insider threats before they escalate. Configure alerts for high-risk actions like bulk document downloads, off-hours access to financial records, or data transfers to personal cloud storage accounts. Solid threat intelligence requires visibility into both external attackers and internal actors, especially temporary ones.
Ransomware response decisions — including who to hire, what data to share, and when to pay — are made under extreme time pressure, often by executives with limited cybersecurity training. Schedule a dedicated security awareness session for your leadership team and legal counsel that covers vendor risk management, insurance data confidentiality protocols, and the warning signs of a compromised negotiator or incident responder (such as a negotiator who discourages bringing in additional advisors or pressures quick payment without exploring alternatives). Reinforce that incident response is a sensitive engagement requiring the same data protection standards as any other third-party relationship involving confidential financial information.
Frequently Asked Questions
How can small businesses protect themselves from insider threats during a ransomware incident response?
Start by limiting what any single vendor or consultant can access. Apply the principle of least privilege — give external parties access only to what they need for their specific task, and revoke access immediately when the engagement ends. Use behavioral monitoring tools to log all activity during an incident. Require vendors to sign data handling agreements before they touch any financial or insurance documents. Finally, always bring in a second, independent party (such as your legal counsel or a trusted technology advisor) to provide oversight during negotiations. The insider threat in this case worked because there was no independent check on Martino's communications.
What are the warning signs that a ransomware negotiator may be acting in bad faith or is compromised?
Red flags include a negotiator who discourages transparency with your leadership or legal team, who pushes for rapid payment without exploring alternatives such as backups or decryption tools, or who asks for detailed insurance coverage information beyond what is necessary to frame a negotiating position. You should also be suspicious if a negotiator seems to know the attacker's "final" number suspiciously quickly, or if ransom demands escalate in ways that suspiciously mirror your disclosed coverage limits. Always verify a negotiation firm's references independently and ask specifically about how they handle sensitive financial data shared during engagements.
How did the FBI disrupt the BlackCat ALPHV ransomware operation, and what happened to victims afterward?
In December 2023, the FBI — in coordination with Europol and law enforcement agencies from Germany, Denmark, Australia, Spain, the United Kingdom, Austria, and Switzerland — conducted a disruption operation against the BlackCat/ALPHV infrastructure. As part of this operation, authorities developed and distributed a decryption tool to over 500 BlackCat victims, allowing them to recover encrypted data without paying a ransom. However, the disruption did not stop all ongoing attacks, and BlackCat operators attempted to regroup. The operation demonstrated that international law enforcement cooperation and proactive threat intelligence sharing can produce tangible results for victims — but also underscored that prevention is far preferable to recovery after the fact.
What cybersecurity best practices should organizations follow when vetting an incident response firm?
Before signing a contract, verify the firm's professional credentials and certifications (such as CREST or SANS GIAC designations), check references from past clients who experienced similar incidents, and review the firm's conflict-of-interest policy in writing. Ask explicitly whether the firm performs both incident response and ransomware negotiation — dual roles create the exact conflict of interest exploited in this case. Require a detailed data handling agreement that specifies what information the firm can access, how it is stored, and who it can be shared with. Finally, ensure your legal counsel reviews all agreements before an incident occurs, not during one. Security awareness at the procurement level is your first line of defense against vendor-side insider threats.
How does AI-powered threat detection help prevent insider threats during an active cybersecurity incident?
AI-driven behavioral analytics tools continuously learn the normal activity patterns of every user — including temporary contractors and external vendors — and immediately flag deviations. During a ransomware incident response, this means the system can alert your security team if a negotiator suddenly downloads large volumes of insurance documents, accesses systems outside their authorized scope, or transfers files to an external destination. Unlike rule-based monitoring (which only catches known bad behaviors), AI systems can identify novel threat patterns in real time, providing a critical safety net during high-pressure situations when human oversight is stretched thin. Pairing AI threat detection with strong data protection policies and access controls gives organizations a layered defense against both external attackers and the insider threats this case made impossible to ignore.
