TClaude Outage Data Leak Fears, Microsoft GitHub Worm, IBM Hack Allegations, Meta AI Instagram Takeovers, and Canada's Bill C-8
David Shipley reports that Anthropic's Claude suffered a roughly two-hour outage affecting models including Opus, during which a user alleged receiving another customer's conversation; Anthropic says it has no evidence of a data leak and is investigating. A Team PCP self-spreading worm, Miasma, infected 73 Microsoft GitHub repositories across four accounts and now triggers via AI coding assistants when developers open cloned projects. A former IBM threat-intel executive, William Barlow, alleges IBM was hacked three times by foreign governments (including APT10 from 2013–2016) and concealed it; IBM denies wrongdoing and the claims are unproven. TechCrunch reports attackers hijacked Instagram accounts by persuading Meta's support chatbot to relink accounts to attacker emails, with ongoing reports despite Meta saying it's fixed. Canada's Senate passed critical-infrastructure cybersecurity law Bill C-8, mandating rules and incident reporting for telecom, finance, energy, and transportation.

Host Jim Love and panelists David Shipley, Laura Payne, and Jeff Williams discuss a researcher ("Chaotic/Nightmare Eclipse") publicly disclosing multiple Windows zero-days affecting components including Defender and BitLocker, frustration with Microsoft's vulnerability disclosure process, and backlash to Microsoft's initially threatening tone before it was partially walked back; the panel debates responsible disclosure, the need for researcher support/organization, transparency vs liability, and how vulnerability reporting is straining under volume. They then examine a White House AI executive order focused on voluntary measures and 30-day model access, criticizing the lack of basic safety and cybersecurity protections amid FOMO about losing to China and an AI investment bubble. The conversation covers AI-driven harms and studies on reduced brain activity and "cognitive surrender," while noting benefits when AI is used as a tutor. Shipley highlights Canada's Senate passing Bill C-8 on critical infrastructure cybersecurity, and the group urges outcome-focused security, architecture/risk prioritization, and critical thinking against AI-enabled social engineering.

A newly disclosed attack called HTTP/2 Bomb can crash major web servers in seconds using a single computer and a modest internet connection. Researchers say the attack combines two known techniques into a powerful memory-exhaustion exploit affecting widely used platforms including Apache, NGINX, Microsoft IIS, and Envoy. The attack also highlights a growing trend in cybersecurity research: the use of artificial intelligence to uncover dangerous combinations of existing vulnerabilities.
The episode also examines President Trump's new executive order creating a voluntary framework for reviewing advanced AI models before public release. The administration says the goal is to improve cybersecurity and national security visibility while avoiding mandatory regulation or licensing requirements.
Next, a new Cloud Security Alliance report warns that organizations are struggling to keep up with the growing volume of vulnerabilities. Security teams increasingly face difficult choices about which flaws to patch first as cloud environments, containers, APIs, and third-party software continue to expand the attack surface.
Finally, CISA warns that attackers are actively exploiting both a newly patched Android vulnerability and a years-old Linux flaw. The contrast highlights a simple reality: cybercriminals do not care whether a vulnerability is new or old. They care whether it remains exploitable.
Stories in this episode
HTTP/2 Bomb Can Crash Web Servers in Seconds
Researchers disclose a denial-of-service technique capable of exhausting server memory in under a minute, while OpenAI's Codex helps uncover a novel attack chain.
Trump Creates Voluntary AI Security Reviews as Government Seeks Visibility Into Frontier Models
A new executive order establishes voluntary reviews of advanced AI systems before public release, raising questions about visibility, oversight, and national security.
The Cybersecurity Industry's Patch-Everything Strategy May Be Breaking Down
A Cloud Security Alliance report suggests organizations are overwhelmed by vulnerability volume and increasingly forced to choose which risks to address.
CISA Warning Shows Attackers Don't Care Whether a Vulnerability Is New or Old
Active exploitation of both a newly patched Android flaw and an older Linux vulnerability demonstrates that attackers focus on opportunities, not disclosure dates.

Cybersecurity Today for June 2, 2026.
Microsoft has backed away from its hard-line stance against vulnerability researchers after widespread criticism from the security community. The dispute began after independent researcher Nightmare Eclipse published proof-of-concept code for unpatched Microsoft vulnerabilities, triggering a public debate over responsible disclosure, zero-days, and researcher relations.

Carnival Corporation disclosed a social-engineering attack that led to the theft of sensitive personal information affecting nearly six million people. Exposed data includes names, contact information, dates of birth, and government identification details. The ShinyHunters cybercrime group has claimed responsibility and alleges the breach involved even more records.
Password manager provider Dashlane temporarily locked some customers out of their accounts after large-scale password-guessing attacks triggered automated security protections. Access was later restored, although some users reported lingering issues.
The episode also examines a software supply-chain attack uncovered by Wiz involving 32 Red Hat Cloud Services NPM packages. Attackers compromised a Red Hat employee's GitHub account and inserted Miasma malware designed to steal Google Cloud and Microsoft Azure credentials.

The episode also explores a new category of insider risk after U.S. prosecutors charged Google security engineer Michael Spagnuolo with allegedly using confidential Google search trend data to earn more than $1.2 million on the prediction market Polymarket. The case highlights how prediction markets may create unexpected incentives around non-financial corporate information.
Also covered: active exploitation of Palo Alto Networks' GlobalProtect VPN authentication bypass vulnerability CVE-2026-0257, now added to CISA's Known Exploited Vulnerabilities (KEV) catalogue, and a malware campaign that abuses legitimate ChatGPT sharing pages and Google Ads to trick users into downloading malicious software. Researchers also report similar abuse of Anthropic's Claude Artifacts feature.
