Executive Risk & Board AdvisoryApollo. Blackstone. Bridgewater. Bain. The Same Crew Is Vishing Them All — And Bain Is Already a Defendant.
Apollo, Blackstone, Bridgewater, and Bain Capital are all in the crosshairs of the same vishing campaign. Bain is already a defendant in the first sponsor-liability ruling. Two-front war on PE.
Executive Risk & Board AdvisoryTake-Two Lost $2.8 Billion. The Hacker Cashed Out $250,000. Nobody Ever Sent a Ransom Note.
CyberLeek leaked GTA VI, pumped a memecoin, and cashed out $250K without ever demanding a ransom. What the first market-monetized extortion means for boards and deal teams.
Executive Risk & Board AdvisoryThree Breaches, Three Years. Client Tax Records in a Hacker's Hands. EY Still Won't Name the Platform That Failed.
EY was breached a third time in three years, and this time the stolen files are client tax records. What boards and PE deal teams should be asking now.
Executive Risk & Board AdvisoryAmazon's One Medical Confirms a "Limited" Breach. ShinyHunters Claims 8.8 Terabytes and a Deadline. Only One of Those Is Verified.
On June 13, One Medical disclosed unauthorized access to a third-party file storage system holding archived records from its legacy Iora Health and One Medical Seniors patients, describing the scope as a limited subset of files at nine named clinics. Days earlier, on June 18, ShinyHunters posted One Medical to its dark-web leak site, claimed 8.8 terabytes of stolen data, and gave the company until June 22 to begin negotiating before publication. ShinyHunters has released no sample data, so the claim is unverified. This is the same actor, the same playbook, and the same trust gap Cloudskope documented in the Canvas/Instructure breach: a company describing the smallest defensible version of events while a threat actor describes the largest. For boards in healthcare and any regulated-data business, the lesson is not which number to believe. It is to treat both as unproven until the evidence settles it, and to plan for the larger one.
Executive Risk & Board AdvisoryDrift. Gainsight. Now Klue. And This Time, It Wasn't ShinyHunters.
For the third time in ten months, attackers drained Salesforce data through a trusted app. The first two were ShinyHunters. This one wasn’t — and that is why it matters.
Executive Risk & Board AdvisoryOperation Epic Fury. Volt Typhoon. BRICS Settlement Rails. Your Portfolio's Cyber Risk Just Became a Geopolitical Position.
The convergence of Operation Epic Fury, Volt Typhoon's pre-positioned access inside US infrastructure, and BRICS de-dollarization is not a geopolitics story. It is a portfolio risk story. Ray Dalio calls this Stage 6 of the Big Cycle — the restructuring phase, where debt-laden empires compete through proxies and economic warfare rather than direct confrontation. Paul Kennedy called the underlying dynamic "imperial overstretch." Jared Diamond would note the resource pressure and institutional fragility. Thomas Friedman would observe that the world is no longer flat. For PE deal teams and portfolio operators, the relevant question is not who wins the geopolitical contest. It is which of your portcos are inside the blast radius of a conflict none of them signed up for.
Executive Risk & Board AdvisoryFive Cyber Questions That Change What a Deal Is Worth.
Cyber due diligence is usually a checkbox near the end of the process. Five specific questions turn it into a deal-pricing input, surfacing the risks that actually move valuation and post-close cost.
Executive Risk & Board AdvisoryAcquisition Agreements Get Signed on Cyber Reps Nobody Verified. That Becomes the GC's Problem.
Acquisition agreements get signed on cyber reps no one independently verified. When the deal closes, the gap between what was repped and what's true becomes the buyer's liability and the GC's problem. What deal counsel should require first.
Executive Risk & Board AdvisoryThe First 100 Days After Close Decide Your Cyber Risk for the Whole Hold.
Cyber due diligence is a screen, not a clean bill of health. The day a deal closes, every undetected weakness becomes the sponsor's problem, and the first 100 days are the only window with the leverage to fix it.
Executive Risk & Board AdvisoryYour Cyber Budget Is a Number. Your Cyber Risk Is a Distribution. CFOs Keep Confusing the Two.
Global cyber spending hit a record $219 billion in 2025, the same year breaches set their own record. The disconnect exposes the core CFO error: treating cybersecurity as a budget number instead of a loss distribution to reshape.
Executive Risk & Board AdvisoryFour Breaches in Six Weeks. One Extortion Group. Your Portfolio Is the Target List.
ShinyHunters spent early 2026 running one pay-or-leak campaign through Instructure, Adobe, Match Group, and DentaQuest. The target profile is a near-perfect description of the average PE portfolio company.
Executive Risk & Board AdvisoryWhat CISA's CI Fortify Guidance Actually Means, and Why It Reads Like a Confession
CISA's CI Fortify guidance tells critical infrastructure to plan for months running cut off from its own networks, on the assumption the adversary is already inside. Why that reads like a confession.

A document-by-document reconstruction of the Canvas/Instructure breach, where the company's own SOC 2 renewal, incident page, and containment claims do not reconcile with what it later admitted.
Executive Risk & Board AdvisoryInstructure Paid Off Its Hackers. The House Homeland Security Committee Wants to Know Why.
On May 12, 2026, Instructure announced a settlement with the ShinyHunters criminal organization that breached its Canvas platform, claiming that all stolen data has been "returned" and that the threat actor has provided "digital confirmation of data destruction." The same day, the House Homeland Security Committee sent a letter to Instructure CEO Steve Daly requesting a briefing on the breach response and on the adequacy of coordination with federal law enforcement and CISA. A settlement is not a resolution. A promise from criminals is not a defensive posture. The pattern of conduct that produced three breaches in eight months has not been addressed. The students at 8,809 schools whose data was taken were not parties to the agreement that supposedly now protects them.
