🎙️ New #ShadowTalk Episode: SonicWall, MFA Bypass, IABs: Why Patched Devices Are Still Handing Attackers Initial Access
When two authoritative CVSS scores diverge on the same vulnerability, teams without a written process fail to prioritize properly. As we've seen, that gap may just be the difference between an urgent manual-remediation and a routine firmware update while threat actors are already inside.
This week, we dig into how scoring divergence and untracked post-patch configuration steps compound into a problem that policy has to close.
🔍 Key Insights:
• Many patch-management workflows close advisory tickets when the firmware version matches the patch release — but they have no mechanism to verify whether mandatory post-patch configuration steps were completed, leaving devices fully exploitable while showing as remediated.
• EPSS, factoring in PoC availability, attacker targeting patterns, asset prevalence, and real-time threat intel, gives defenders a dynamic exploitation-probability signal that a single static CVSS score cannot provide.

💬 Does your vulnerability-management policy have a written rule for which scoring authority wins when CISA, NVD, and the vendor publish different scores for the same CVE — and if not, what's the default?

🎙️ New #ShadowTalk Episode: Device Code, OAuth, PhaaS: How Session Token Theft is Breaking the Phishing Playbook
One campaign. April–May 2026. 35,000+ users, 13,000+ organizations, 26 countries. Not a single password stolen. The MFA prompt fired, the user passed it, and the authenticated session token landed on the attacker's device.
This week, we dig into why device code phishing is the technique your current defenses are least configured to stop, and why the high-volume phishing inbox your team is already drowning in is the exact cover these campaigns run on.
🔍 Key Insights:
• Device code phishing abuses a legitimate OAuth 2.0 flow, the victim authenticates at a real login page, MFA passes, and the token is delivered to the attacker's device, not theirs.
• As of May 2026, attackers are registering 3+ rogue devices per compromised account within seconds of initial compromise.
• A major AiTM PhaaS platform added device code phishing to its toolkit in May 2026, putting this tradecraft within reach of lower-skilled actors and signaling rapid proliferation ahead.
💬 If a confirmed phishing report landed on your team right now, would your token revocation workflow fire automatically — or does someone have to kick it off manually?

Between February and March 2026, we identified what we assess to be the first in-the-wild exploitation of CVE-2024-12802, an auth bypass in SonicWall SSL VPN that reduces security to single-factor even when MFA appears enabled.
On Gen6 devices, patching the firmware isn't enough. Six manual LDAP reconfiguration steps are required, and standard patch workflows can't verify them. Devices showed as "patched" while remaining fully exploitable.
Attackers brute-forced VPN credentials using automated tools and bypassed MFA silently with no failed login alert and no anomalous flag. In some cases it took as few as 13 attempts to land a valid credential. In one environment, the attacker went from VPN auth to file server to Cobalt Strike beacon and a BYOVD driver load in under 40 minutes. EDR stopped the payload, but the attacker adapted and started manually hunting for credentials through Notepad, a technique that blends right into normal file server activity.
The pattern is consistent with initial access broker activity feeding into the ransomware ecosystem. The tools match TTPs seen in previous Akira-linked intrusions.

🎙️ New #ShadowTalk Episode: SQLite, Mistral, OpenAI: How AI Attacks Are Reshaping the Attack Surface
An AI agent found a memory-safety zero-day in SQLite in hours, not weeks. State-backed actors from three countries are already running the same playbook. This week, we unpack why the defender's intel-to-action chain, still measured in days, is the real structural gap.
🔍 Key Insights:
• Shadow AI infrastructure (Ollama, Open WebUI, agent frameworks) is landing on networks unauthenticated and off the asset register.
• Registry compromise is reaching AI vendors directly — the TanStack worm hit Mistral's dependencies and two OpenAI employee devices.
• Pre-approved rotation playbooks and AI-driven hunts close the gap when human-paced response can't keep up.

💬 What's your median time from "advisory published" to "response action executed"? Hours or days?

Help desk impersonation is evolving past credential theft into hands-on-keyboard intrusion.
In a recent campaign, attackers spoofed IT support via Microsoft Teams, walked victims through a ClickFix lure, and dropped an evolved variant of "ModeloRAT" tracked as "Kongtuke." The payload established persistence, dumped credentials, and pivoted toward domain controllers, all under the cover of a routine support session.
The lure looks like helpdesk noise, but the chain ends in pre-ransomware staging. If affiliates standardize this pattern, the line between social engineering delivery and full hands-on-keyboard intrusion becomes harder to draw.

🎙️ New #ShadowTalk Episode: Canvas, Trellix, Mini Shai-Hulud: How Defenders Respond When Supply Chain Attacks Become Weekly
275 million records is the headline. The harder number is 8,809 institutions now stuck dealing with the downstream fallout from the Canvas breach.
This week, we dig into Canvas, Trellix, and the latest Shai-Hulud-style package compromises to show why supply chain attacks are now landing weekly—and why the real defender problem starts after the supplier gets hit.
🔍 Key Insights:
• Instructure confirmed 275 million records and 3.65 TB of data across 8,809 educational organizations after ShinyHunters abused admin sessions and native export/API features.
• In the Trellix case, there’s no evidence source code or distribution processes were affected—but RansomHouse is known to use hypervisor-focused automation that can outpace manual response.
• Mini Shai-Hulud hit 170+ npm packages across projects tied to TanStack, UiPath, Mistral AI, OpenSearch, and Guardrails AI by abusing legitimate publishing workflows.

💬 Which downstream risk is hardest to contain right now: trusted communications, exposed cloud secrets, or poisoned software pipelines?
#ShadowTalk #CyberSecurity #SupplyChainSecurity #AppSec
🚨 ClickFix is starting to look less like a delivery mechanism and more like a launchpad for modular post-exploitation.
In a recent intrusion, one pasted command triggered persistence, domain enumeration, a PowerShell C2 loop, and the deployment of PySoxy as an encrypted proxy, all without dropping traditional malware. Both C2 channels were blocked, but a scheduled task kept relaunching the chain for hours, reinforcing that a blocked callback is not containment.
The chain bears operational resemblance to SocGholish pre-ransomware staging, and if affiliates begin treating ClickFix as an equivalent initial-access source, the implication is that social engineering delivery paired with bring-your-own-interpreter post-exploitation could become a more common path to ransomware deployment.

RansomHouse's claim against Trellix is interesting, but the more important takeaway is the realistic possibility the group used MrAgent, a custom management tool designed to automate and track ransomware deployments across ESXi hypervisor environments.
If true, the implication for defenders is significant: once operators gain access to hypervisor management, they may be able to move from initial foothold to widespread encryption far faster than traditional intrusion timelines would suggest. In ESXi environments, automation at the management layer can compress the time between access and impact, leaving defenders with much less time to detect, investigate, and contain the intrusion.
🎙️ New #ShadowTalk Episode: Akira, ShinyHunters, and The Gentlemen: Extortion Lessons From Early 2026
Q1 2026 leak-site posts jumped 22% YoY. But the more useful stat might be this: ShinyHunters named just 34 victims while one technique alone may have exposed 300–400 orgs.
This week, we help cut through the noise to data leak sites and dig into how Akira, ShinyHunters, and The Gentlemen are exploiting inherited infrastructure, SaaS and identity blind spots, and automation that outruns manual response.
🔍 Key Insights:
• Akira hit inherited SonicWall SSL VPNs in M&A environments and attempted lateral movement within 6 minutes of access.
• ShinyHunters paired help-desk vishing on personal phones with lookalike phishing domains and SaaS/API abuse that can bypass endpoint visibility.
• The Gentlemen grew 588% QoQ with a 90/10 affiliate split, automated spread, EDR-killer tooling, and self-delete features.

💬 Which gap is hardest to close right now: inherited assets, SaaS visibility, or response speed?
#ShadowTalk #CyberSecurity #Ransomware #IdentitySecurity #SaaSSecurity
The group claims its attack on Ubuntu servers is ongoing and escalating, with indications of increased DDoS intensity. They have also issued an extortion demand, stating that their "communication channels remain open for Ubuntu to contact us so that we may agree on a ceasefire." X has since suspended the group's account.
🚨 Iran-aligned hacktivist group Team 313 (Islamic Cyber Resistance in Iraq) claims an ongoing attack against Ubuntu's core infrastructure, alleging that standard updates, security patches, and CI/CD pipelines have been disrupted.
The group is also urging hackers to exploit CVE-2026-31431 ("Copy Fail"), claiming most Ubuntu systems are now vulnerable, and has published exploit material to lower the barrier. Ubuntu has released mitigations via kmod updates, but the kernel-level fix remains unavailable. Team 313 has been increasingly active since the Iran-US-Israel conflict escalated in early 2026 and has deployed wiper malware against at least one major US enterprise.

Vidar has taken center stage.
The infostealer has climbed to the top of the market following law enforcement takedowns of Lumma and Rhadamanthys in 2025. According to security researchers, Vidar has been the most used stealer on Russian Market since November 2025. It secured that position by releasing a major upgrade and expanding its distribution network while its rivals were being disrupted.
Its C2 evasion technique stands out. Rather than hardcoding a server address, Vidar uses "dead drop resolvers." The malware points to legitimate public platforms like Telegram, where operators embed the real C2 address inside profile bios or post descriptions. It retrieves that address dynamically at runtime, sidestepping static detection and domain blocking.
The takedown of two top tier infostealers did not shrink the threat landscape. It reshuffled it. Vidar stepped in, upgraded, and expanded while its rivals were down. Stolen credentials are hitting underground markets and being used for account takeovers, lateral movement, and ransomware staging.

Attackers are moving faster and starting higher up the org chart. In 2025, average breakout time (initial compromise to lateral movement) dropped 29%, from 48 minutes to just 34. One tactic fueling that speed is a shift away from privilege escalation toward arriving with elevated credentials from the start, reflected in a 15% decline in privilege escalation activity in 2025, as threat actors lean harder on credential theft and social engineering.
This trend is continuing into 2026: from March 1 to April 1, 2026, 77% of observed Microsoft Teams phishing attempts targeted senior-level employees, up from 59% in the first two months of the year.
For security teams: tighten identity controls around privileged accounts, shrink detection and response windows, and assume initial access already includes the keys to the kingdom.

TeamPCP is making moves.
A threat actor hijacked the official Bitwarden CLI on npm. The attack has been linked to the Checkmarx supply-chain compromise previously claimed by TeamPCP. When users installed the malicious version, it downloaded a JavaScript runtime in the background, launched a hidden payload, and attempted to collect sensitive data from the host — including GitHub tokens, npm tokens, SSH keys, AWS credentials, cloud secrets, and AI tool configurations.
The exfiltration method stands out. If the primary server was blocked, the malware fell back to GitHub, created a repository in the victim's own account, and uploaded the stolen data there. That approach is effective because most environments do not flag outbound traffic to GitHub as suspicious.
The infrastructure and delivery pattern are consistent with the broader campaign observed across recent investigations. If you installed @bitwarden/[email protected], rotate all potentially exposed credentials immediately.

Multiple actors are now claiming access to Claude Mythos.
A Discord group says they guessed the model URL based on Anthropic's naming conventions. One member claims insider access through a third-party contractor. Separately, an unverified actor using the ShinyHunters name is advertising roughly 3,000 internal documents and an "active zero-day" for sale.
Anthropic's own investigation tells a different story. Unauthorized access involved someone playing around with the model. No offensive prompts. No damage. No zero-day.
Both claims are low confidence and look opportunistic. This is what riding a hype cycle looks like.

One compromised OAuth integration. Potentially dozens of downstream victims. That's ShinyHunters' playbook — and it's working.
A Lumma infostealer on a https://t.co/OMxOi2ieW3 employee's machine harvested Google Workspace credentials, which were likely used to pivot directly into Vercel — a PaaS platform powering thousands of web applications — via an OAuth integration. A threat actor on BreachForums subsequently claimed to sell stolen credentials, API keys, and source code alongside a $2 million ransom demand. This mirrors the Anodot compromise, where the same extortion pattern enabled downstream data theft from over a dozen organizations, including Rockstar.
For security teams, two gaps are enabling attacks like this: incomplete logging visibility and unenforced conditional access policies on unmanaged devices.

🚨 Former Black Basta affiliates are likely automating the targeting of senior employees.
In the first four months of 2026, ReliaQuest observed a sharp rise in Black Basta-style Teams phishing. 56% of all such activity seen since the group’s decline occurred this year alone. In March, 77% of targeted users were executives, directors, or managers. In some cases, attackers went from initial Teams contact to malicious script execution in as little as 12 minutes.
The playbook is familiar: mass email bombing followed by Microsoft Teams-based help desk impersonation to pressure users into granting remote access. ReliaQuest also observed signs that parts of the workflow are becoming increasingly automated, including outreach attempts launched within seconds of one another.
For security teams, email bombing should be treated as an early warning sign. Any help desk request involving remote access should be verified out of band, and suspicious Teams, Quick Assist, or Supremo activity involving senior users should be treated as high priority.
