Daily technology news recap for Wednesday, June 3, 2026. Today has a useful mix of good news and bad news. The good news: major technology companies are adding stronger tools for scam-call detection, AI-assisted cyber defense, and account protection. The bad news: CISA added newly exploited vulnerabilities to its Known Exploited Vulnerabilities catalog, including a critical Magento extension issue that matters to ecommerce sites and the vendors that support them.
This roundup is written for home users and small businesses that want the practical version of the news: what changed, why it matters, what is worth doing now, and what can wait. Technology headlines move quickly, but the basics still win: update exposed systems, protect important accounts, avoid rushing beta software onto production devices, and make sure somebody owns patching for websites, phones, servers, and business applications.
In This Article
- CISA adds exploited vulnerabilities, including a Magento cache extension issue
- Android’s June update story includes both patches and scam-call protection
- AI cyber-defense programs are expanding, but that creates a patching problem too
- AI accounts and connected tools need stronger account security
- Apple WWDC26 starts next week, so businesses should prepare instead of guessing
1. CISA Adds Exploited Vulnerabilities, Including A Critical Magento Cache Extension Issue
CISA’s Known Exploited Vulnerabilities catalog was updated on June 3, 2026, with catalog version 2026.06.03. The same-day addition that should catch the attention of website owners and ecommerce operators is CVE-2026-45247, a Mirasvit Full Page Cache Warmer vulnerability. CISA describes it as a deserialization of untrusted data issue that can allow unauthenticated remote code execution through a crafted serialized PHP object in the CacheWarmer cookie.
That sounds technical, but the practical meaning is simple: if a Magento or Adobe Commerce site is running a vulnerable version of that extension, an attacker may not need a password to try to run code on the server. Sansec’s original research says the affected extension is used for Magento full-page cache warming and that Mirasvit released patched version 1.11.12 on May 25, 2026. NVD lists the issue as affecting Mirasvit Full Page Cache Warmer for Magento 2 before version 1.11.12.
The good news is that there is a patched version. The bad news is that CISA adding the issue to the exploited catalog means defenders should treat this as more than a theoretical bug. Federal civilian agencies get a short required remediation timeline under CISA rules, but private businesses should not wait just because they are not directly covered by that directive.
Local-business takeaway: if you operate an online store, ask whoever manages the site whether it runs Magento or Adobe Commerce and whether the Mirasvit Full Page Cache Warmer extension is installed. If it is installed, verify the version is 1.11.12 or later, review logs for suspicious CacheWarmer cookie activity, and scan for unexpected PHP files or web shells. This is also a good reminder that performance plugins, cache tools, page builders, SEO plugins, payment plugins, and shipping plugins are part of your attack surface.
What home users should know: this is mostly a website-owner issue, not something you patch on your personal laptop. But if you shop at small ecommerce sites, remember that compromised stores can lead to fake checkout pages, stolen login details, malicious redirects, or follow-up phishing. Use credit cards or protected payment methods, avoid saving cards on unfamiliar stores, and watch for odd checkout behavior.

2. Android’s June Story Includes Security Patches And Better Scam-Call Protection
Android is worth watching from two angles this week. First, Google’s Android Security Bulletin for June 2026 says Android security patch levels of 2026-06-05 or later address the listed June issues. That matters because phones are no longer casual devices. For many people, a phone is the MFA device, banking device, customer-message device, payment app, business email device, and password-reset device.
Second, Google’s June Android Drop adds more practical anti-scam features. Google’s security blog described Android fake call detection on June 2, explaining that scammers can use AI voice tools to impersonate trusted contacts. Google’s feature is meant to help warn users when a call that appears to come from someone they know may not actually be from that person’s device.
The good news is that scam-call protection is getting more realistic. Caller ID alone is weak because numbers can be spoofed. A warning tied to whether the call is actually coming from the contact’s device is a more useful signal than simply trusting the displayed name. The bad news is that scammers keep adapting. If a caller says they are a family member, employee, bank, vendor, or customer and demands money, gift cards, passwords, remote access, or urgent account changes, slow down and verify through a separate trusted channel.
What to check now: on Android, open Settings and look for Security, Privacy, System update, Android security update, or similar wording depending on the brand. Install the June update when your manufacturer or carrier makes it available. If your phone is stuck months behind on security updates and you use it for business email, banking, MFA, or customer communication, start planning a replacement or a managed-device policy.
Local-business takeaway: add phone patch level to your device inventory. A basic list with employee name, phone model, owner, work apps, Android version, security patch level, and lost-device process is enough to start. For small offices, the biggest improvement is often not a fancy tool. It is knowing which devices are used for work and which ones are too old to trust.

3. AI Cyber-Defense Programs Are Expanding, But Finding Bugs Faster Is Only Half The Job
Anthropic announced on June 2 that it is expanding Project Glasswing, its defensive cybersecurity program built around Claude Mythos Preview, to approximately 150 new organizations across more than 15 countries. The company says early partners have found more than 10,000 high- or critical-severity security flaws. That is meaningful because it points to a future where AI systems help defenders find vulnerabilities in code, open-source dependencies, infrastructure software, and critical systems more quickly than traditional review alone.
The good news is obvious: better defensive tools can help vendors and infrastructure operators find dangerous bugs before attackers do. If AI-assisted review helps maintainers spot and fix flaws in browsers, servers, libraries, payment systems, cloud services, or security tools, ordinary users and businesses benefit downstream.
The caution is equally important. Finding bugs faster does not automatically mean fixing bugs faster. Every serious vulnerability still needs triage, owner assignment, patch development, testing, deployment, rollback planning, monitoring, and customer communication. Small businesses feel this as a vendor-management problem: your website host, software vendor, MSP, firewall vendor, app provider, and plugin developer may know about fixes before you do, but you still need a process for asking what was patched and when.
Local-business takeaway: use today’s AI-cybersecurity news as a reason to tighten your patch ownership. For each important system, write down who patches it: Windows PCs, Macs, phones, website, WordPress/Magento plugins, firewall, Wi-Fi, NAS, accounting software, payroll, line-of-business apps, and cloud accounts. If the answer is “I think it updates itself,” verify it. Automatic updates are useful, but they are not a replacement for accountability.

4. AI Accounts And Connected Tools Need Stronger Account Security
Another current AI-security lesson is account protection. OpenAI’s recent Advanced Account Security guidance is not a June 3 breaking story, but it is still materially relevant this week because OpenAI said individual members of Trusted Access for Cyber using its most cyber-capable access paths would need Advanced Account Security beginning June 1, 2026. The broader lesson applies beyond OpenAI: AI accounts increasingly hold sensitive business context, connected files, code, customer data, drafts, support details, and automation permissions.
The good news is that stronger sign-in methods such as passkeys and security keys are becoming more normal. The bad news is that many businesses still protect critical SaaS accounts with reused passwords, SMS recovery, shared logins, unmanaged browser sessions, and old devices that nobody reviews. That is risky even before AI tools are connected to email, file storage, code repositories, ticketing systems, or customer records.
What to do this week: for AI tools used at work, check who owns the account, whether MFA is required, whether passkeys or physical security keys are available, what data the tool can access, whether old sessions can be reviewed, and whether the account is tied to one employee’s personal email. If the account can call APIs, access shared files, write code, or connect to customer systems, treat it like a real business system.
Local-business takeaway: do not let a powerful AI account become a mystery admin account. Use individual user accounts where possible, protect owner accounts with phishing-resistant MFA, store recovery codes safely, remove access when staff leave, and document which AI tools are approved for customer or confidential work.

5. Apple WWDC26 Starts June 8, So Prepare Instead Of Guessing
Apple’s WWDC26 starts Monday, June 8, 2026, and runs June 8-12. This is not a same-day emergency, but it is timely planning news. Apple’s developer site is already live for WWDC26, and the annual conference usually sets expectations for iPhone, iPad, Mac, Apple Watch, Vision Pro, Xcode, app compatibility, and developer-tool changes.
The good news is that Apple announcements often bring useful productivity, privacy, security, and device-management improvements. The bad news is that early betas can break apps, drivers, VPN tools, printers, accounting software, medical or legal apps, payment systems, browser extensions, and line-of-business workflows. A shiny feature is not worth taking down the device that handles customer calls or two-factor approvals.
Local-business takeaway: before WWDC turns into beta downloads and fall upgrades, make a simple Apple device list. Include Macs, iPhones, iPads, the apps they depend on, and whether each device is personal or company-owned. Decide who is allowed to install betas. For most businesses, beta software belongs on test devices only.

Good News And Bad News At A Glance
- Good: Android is getting more useful anti-scam protections, including fake-call detection aimed at AI voice impersonation.
- Bad: phone updates still depend on device maker, carrier, age, and business management setup. A phone that cannot receive current patches should not be trusted for sensitive work forever.
- Good: AI-assisted security research could help find severe vulnerabilities earlier.
- Bad: finding vulnerabilities faster creates pressure on vendors and businesses to patch, test, and verify faster.
- Good: CISA’s exploited-vulnerability catalog gives defenders a practical priority list.
- Bad: the June 3 Mirasvit/Magento entry is a reminder that third-party website extensions can become urgent security problems.
- Good: passkeys, security keys, and stronger account-security settings are becoming more available.
- Bad: many small businesses still rely on shared logins, weak recovery methods, and undocumented account ownership.
What Home Users Should Check Tonight
- Check Android updates. Install the June 2026 security update when your device maker provides it.
- Be skeptical of urgent voice calls. If a caller asks for money, passwords, gift cards, codes, remote access, or account changes, verify through another channel.
- Review important accounts. Email, banking, cloud storage, password managers, AI accounts, and social accounts should have MFA and current recovery information.
- Avoid beta software on daily-use devices. WWDC betas are for testing, not for the iPhone or Mac you rely on for work.
- Use protected payment methods online. Especially when shopping on small ecommerce sites, avoid unnecessary stored-card risk.
What Small Businesses Should Do This Week
- Ask who patches the website. If you run Magento, Adobe Commerce, WordPress, WooCommerce, Shopify apps, or other plugins/extensions, know who owns updates and backups.
- Check exposed systems first. Websites, VPNs, firewalls, remote access, cloud admin portals, and email admin portals deserve faster attention than low-risk desktop utilities.
- Create a mobile-device inventory. Phones used for business email, MFA, payments, or customer communication should have current security patches.
- Document AI tool usage. Know which AI accounts exist, who owns them, what data they can access, and whether they are allowed for customer or confidential information.
- Prepare for Apple changes. List business-critical Mac and iPhone apps before WWDC, then test before any broad operating-system rollout.
- Use stronger authentication for owner/admin accounts. Passkeys or security keys are worth considering for email, domains, hosting, password managers, accounting, payroll, and AI tools.
FAQ
Does the CISA Magento item affect every small business website?
No. It specifically relates to Mirasvit Full Page Cache Warmer for Magento 2 before version 1.11.12. But the lesson is broader: ecommerce extensions and website plugins need the same patch discipline as the main website platform.
Should I replace my Android phone if it does not have the June patch today?
Not immediately. Many Android updates roll out by manufacturer and carrier. But if your phone is permanently stuck months behind on security patches and you use it for business email, MFA, payments, or banking, replacement planning is reasonable.
Are AI security tools good or dangerous?
Both can be true. AI can help defenders find and fix problems faster, but powerful cyber models and automated agents need access controls, logging, verification, and careful release rules. For small businesses, the practical priority is patch ownership and account security.
Should my business install Apple betas after WWDC?
Usually not on production devices. Use a spare device or limited test group if you need early testing. Keep daily-use phones, Macs, and business-critical machines on stable releases unless there is a specific reason to test.
Can The IT Guys help with this checklist?
Yes. The IT Guys can help review website/plugin patching, mobile-device update status, account recovery, MFA, password-manager setup, AI-tool access, and practical security ownership for home users and small businesses.
