Week in review: Cisco SD-WAN 0-day exploited, Patch Tuesday forecast

Here’s an overview of some of last week’s most interesting news, articles, interviews and videos:

OWASP Agent Memory Guard: Stop AI agents from being weaponized through their own memory
Agent Memory Guard is an open-source runtime defense layer that sits between an agent and its memory store, screening every read and write through a pipeline of detectors and a YAML policy. The project is the OWASP reference implementation for ASI06, Memory Poisoning, one entry in the OWASP Top 10 for Agentic Applications.

Data discovery gaps that catch enterprises off guard
In this interview with Help Net Security, Avani Desai, CEO at Schellman, talks about the gap between what organizations think they know about their data and what discovery scans turn up. She shares stories of shadow data in abandoned cloud storage, post-merger surprises where duplicated datasets slowed integration, and why synthetic data is overmarketed while confidential computing stays underappreciated.

Zero trust physical security needs trust decisions at the edge
In this interview with Help Net Security, Chuck Davis, VP, Global Information Security at Hikvision, explains how zero trust applies to physical security systems like cameras and door controllers. He breaks down how to make trust decisions at the edge without recreating old perimeter assumptions, why these devices should be treated as IT assets, and what the Mirai botnet taught the industry.

A small Slovenian team handles 6,000 cyber incidents a year
Online fraud complaints, ransomware cases, and phishing tips reach Slovenia’s national cyber response center in steady volume, and a team of around a dozen analysts sorts through them. Gorazd Božič, who manages SI-CERT at the public agency ARNES, described that work in an interview conducted in person at the Span Cyber Security Arena conference. He put the original proposal for a Slovenian CERT to ARNES leadership in 1994, and the center now records about 6,000 incidents a year, up from roughly 300 ten to fifteen years earlier.

Only 11% of production agents pass the AI agent security bar
Enterprise teams are running AI agents that write code, drive browsers, answer customer calls, manage cloud infrastructure, and query data warehouses with standing credentials. A new independent assessment of 100 production agents finds that nearly all of them carry the conditions for a single hostile document to take them over.

Spotless compliance evidence can still hide a broken control
In this interview with Help Net Security, Marc Rubbinaccio, Head of Cybersecurity and Compliance at Secureframe, explains where security teams go wrong when preparing for CMMC and FedRAMP 20x. The conversation covers how organizations check the 110 requirements but miss the 320 assessment objectives beneath them, why spotless SOC 2 evidence can hide a broken control, and how continuous monitoring is changing compliance work.

OAuth marketplace apps keep access after publishers vanish
Installing an app from the Google Workspace Marketplace or GitHub Marketplace can grant a third party access to company email, files, calendars, code repositories, CI workflows, organization settings, and secrets. Marketplace presence gives these apps the appearance of approval. The OAuth grants behind them often reach into business systems beyond the listed function.

Thieves can pull off keyless car theft in under a minute and here’s how to stop them
A keyless car can be stolen in under a minute. Two people, a pair of cheap radio amplifiers, and a fob sitting on a hallway table inside the house. That is enough. No broken glass. No alarm. No sound. The vulnerability runs across the global market. Germany’s largest auto club, ADAC, runs ongoing tests of keyless models against relay attacks.

AgentGG: Open-source agentic SAST scanner
Static analysis tools have spent years matching source code against known-bad patterns and handing engineers long lists of candidate issues to triage by hand. AgentGG approaches the same job with AI agents that read the code, follow imports, walk the call graph, and confirm a finding before they report it. The project is an open-source agentic SAST scanner released under the Apache 2.0 license.

Hackers are exploiting Palo Alto GlobalProtect VPN authentication bypass (CVE-2026-0257)
Authentication bypass vulnerabilities (CVE-2026-0257) in Palo Alto Networks’ firewalls that the company disclosed on May 13 have been targeted in “limited exploit attempts”. The good news, though, is that the company hasn’t observed any indication of successful lateral movement from the devices.

Autonomous AI-driven worm can reason its way through corporate networks
Researchers at the University of Toronto, the Vector Institute, and the University of Cambridge have built and tested a proof-of-concept AI-driven worm that does not operate on a fixed list of exploits. Instead, it analyzes each target it encounters, reasons about how to attack it, and creates a strategy on the fly, all with the help of a small, free large language model (LLM) running directly on machines it has already compromised.

Cisco SD-WAN 0-day exploited, no patch available (CVE-2026-20245)
A 0-day privilege escalation vulnerability (CVE-2026-20245) in Cisco Catalyst SD-WAN Manager that has yet to be patched by Cisco is being leveraged by attackers.

June 2026 Patch Tuesday forecast: Where are the CVEs?

The modern-day business can learn a lot about risk from this year’s mega events
Every year brings its share of global events, but 2026 is proving to be a banner year for mega-scale entertainment. The year got off to a roaring start with the Winter Olympics, and now anticipation is building for the fast-approaching FIFA World Cup. But amid the buzz, have you ever paused to consider the staggering level of risk inherent to such large-scale events? Or how impressive it is that organizers are able to manage that risk so successfully?

From critical to controlled: Cutting vulnerabilities in a live manufacturing environment
A vulnerability scanner flags a critical CVSS 10 vulnerability on an industrial asset. The report lands in the boss’ inbox and now he wants to know why we’re sitting on a critical vulnerability. In a normal IT environment, you patch it then close the ticket and call it a day. If, however, you’re in OT or dealing with ICS in a live manufacturing facility, it’s rarely that simple.

Why you need BAS and autonomous pentesting together
A new autonomous penetration testing tool delivers impressive results at first—finding critical issues, uncovering undocumented attack paths, and exposing forgotten accounts. But by the fourth or fifth run, the discoveries dry up. The tool keeps reporting the same stale issues, and the dashboard becomes another source of noise. What seemed like continuous validation quietly turns into a repeat of the same well-worn attack paths.

Governing shadow AI without killing innovation
In this Help Net Security video, Alan Snyder, CEO at NowSecure, talks about governing shadow AI without stopping innovation. He frames the problem as two opposing forces. Companies need to adopt AI fast because attackers and competitors will outpace them otherwise, but they also need to do it safely.

What CISOs need to do about post-quantum migration in the next 24 months
In this Help Net Security video, Garfield Jones, SVP Global Strategy and Research, QuSecure, lays out what CISOs should do over the next 24 months.

NVIDIA goes open source with a big batch of physical AI agent tools
NVIDIA just dropped a big batch of open-source “physical AI” skills and tools, and they’re designed to make a roboticist’s life a whole lot easier. The idea? Take the messy, complicated work behind robots, self-driving cars, vision AI, and industrial digital twins, and break it into bite-sized tasks that AI agents can actually run themselves.

Microsoft Defender Vulnerability Management gets a smarter exposure score
Microsoft Defender Vulnerability Management’s updated exposure score model adds vulnerability risk signals and asset context to help teams understand where risk is concentrated and which remediation actions are likely to have the greatest impact. The model is available in public preview.

This AI model backdoor attack stays hidden until you customize the model
Most teams that deploy AI start with a backbone model. They download a large pre-trained system, adapt it to a specific task, and put it into production. The download step carries a security question: the origin of the model. A research team built an attack called BadBone. It plants a backdoor inside a backbone model. Downstream tasks that adapt the model inherit the backdoor. The name points at the target. Corrupt the skeleton, and systems built on top of it carry the flaw.

OpenAI brings frontier AI to existing AWS environments
OpenAI frontier models and Codex are now available on AWS, giving customers access to OpenAI capabilities within AWS environments and the controls needed to move more quickly from evaluation to deployment. These capabilities are available through OpenAI models on Amazon Bedrock, a platform for building generative AI applications and agents at production scale. The platform enables teams to build AI applications using AWS-native security and governance controls.

The work followed the discovery of multiple security issues in the upstream Linux kernel during the prior month.

Codex knowledge work expands into research, reports, and spreadsheets
Office workers in the United States lose hours each week to email triage and to searching for files spread across disconnected systems. Roughly 40 percent of US labor, about 72 million people, works primarily with information such as analysis, documents, designs, and communication. Research from the McKinsey Global Institute puts the average knowledge worker at 28 percent of the workweek on email and close to 20 percent on hunts for internal information or for colleagues who can help with specific tasks.

Meta adds stricter guardrails for teen feeds
Meta has expanded its Teen Accounts 13+ content settings globally on Instagram, Facebook, and Messenger. The safeguards are designed to help young users see age-appropriate content by default. The company also introduced Limited Content on Instagram for parents seeking stricter restrictions. Meta plans to roll out the feature on Facebook and Messenger later this year.

Known vulnerabilities behind most application security incidents
Eight in ten organizations took an application security hit during the past year tied to a vulnerability their team had already cataloged, according to a survey of 902 IT and security professionals conducted by the Cloud Security Alliance. The pattern points to a structural condition across the industry, where the window between identifying a flaw and closing it in production stays open long enough for attackers to act.

Agent Threat Rules: Open detection rule format for AI agent security threats
AI agents run inside coding assistants, MCP servers, and multi-agent frameworks, and the access that makes them useful also opens paths to prompt injection, tool poisoning, and credential theft. Public CVE feeds carry agent-execution flaws that reach production faster than the tooling built to catch them. Agent Threat Rules, or ATR, is an open detection format aimed at this category of attack.

Microsoft Scout agent opens a new category of always-on Autopilots
Workplace AI assistants have mostly waited for a prompt before doing anything. A user asks, the tool answers, and the exchange ends there. Microsoft is putting a different kind of agent inside its Office applications, one designed to keep operating in the background once a person stops paying attention. The company introduced Microsoft Scout, calling it the first entry in a category it labels Autopilots.

New Android feature promises to spot deepfake scam calls
