A critical zero-day called StyleSmuggler is being actively exploited against Magento Open Source stores, giving unauthenticated attackers remote code execution. Dutch security firm Sansec, which disclosed the flaw on September 5, 2026, says every current version of Magento and Adobe Commerce is affected. It published early because stores were already being compromised.

Sansec reproduced the attack chain on clean 2.4.7, 2.4.8, and 2.4.9 installations, and the first identified victim ran 2.4.6-p15 with July and August 2026 patches applied. The exploit abuses Magento's own template and email systems, dropping a Rust implant disguised as a Linux kernel thread.

Adobe has issued no advisory, CVE, or fix. Its next scheduled security release is September 8, though Sansec says there is no confirmation it covers this bug. Until then, store owners are on stopgaps.

Disrex, ProxiBlue, and Graycore have each published unofficial patches guarding specific Magento classes. Disrex says its own patch is verified against 2.4.6 through 2.4.9. Sansec recommends temporarily disabling GraphQL, which classic and Hyvä themes generally don't need, unlike headless and progressive web app storefronts.

The layer that doesn't depend on knowing the exploit is server-level. Disable PHP's exec functions, proc_open included, since a list blocking five of the six stops nothing, and mount temporary directories with noexec. Check both var/report and var/log/system.log too, since Sansec's published check looks only at the first

McKesson, one of North America's largest pharmaceutical distributors with $403.4 billion in annual revenue, disclosed a cyberattack on August 28, 2026, three days after discovering it. Unauthorized access to certain third-party applications led to data theft affecting a subset of customers within its Oncology & Multispecialty and Medical-Surgical business units, the company says.

ShinyHunters claimed responsibility, though McKesson has not named the group. It says it used voice phishing to compromise employees' Okta single sign-on accounts, then reached the Salesforce and Snowflake environments and exfiltrated data between August 21 and August 25, claiming roughly 284 million records and demanding over $55 million.

That figure counts database rows rather than patients, and the group has not fully analyzed the data. None of its claims are independently verified. A September 1 deadline to open negotiations passed without a response from the company, which has declined to comment on the demand.

Its distribution centers remain operational, McKesson says, though it warned customers to expect intermittent service degradation. Health-ISAC had warned the healthcare sector about ShinyHunters just weeks before the breach.

SonicWall confirmed on Tuesday, September 1, that attackers are actively exploiting two zero-days in its SMA 1000 remote-access appliances. CVE-2026-83548 (SSRF, CVSS 10.0) hits the user-facing Workplace portal; CVE-2026-83549 (OS command injection, CVSS 7.8) sits behind the admin console. Chained, the first supplies the authentication the second needs — unauthenticated remote code execution.

Models 6210, 7210, and 8200v are affected on 12.4.3-03453 or 12.5.0-02835 and older. Upgrade to 12.4.3-03526 or 12.5.0-02952. Patching isn't the end of it: SonicWall says compromised appliances need re-imaging or redeployment, every user and admin password changed, and TOTP tokens reset.

There is little to check against, though: Rapid7 found no public proof-of-concept, no published indicators of compromise, and no attribution — so a verdict runs through SonicWall's support team rather than a threat feed.

This is the second such pair on the SMA 1000 in two months. July's CVE-2026-15409 was the same shape — pre-auth SSRF plus post-auth command injection — and CISA later flagged it as used in ransomware campaigns. NHS England rates further exploitation as almost certain.

The Minnesota Supreme Court, Court of Appeals, Tax Court, and Court of Administrative Hearings all had user data compromised in a breach at their vendor, Thomson Reuters Court Management Solutions. Attackers were inside the C-Track case management platform from March 1 until June 29, and Thomson Reuters only discovered the intrusion on June 30.

The exposed backup data may include names alongside Social Security numbers, driver's license numbers, dates of birth, medical information and health insurance details. Case documents such as orders and briefs were not affected, and Minnesota courts are operating normally. Chief Justice Natalie Hudson called the compromise deeply troubling.

Minnesota's judicial branch has cut Thomson Reuters' access to court information. Every Minnesota C-Track user has to reset their password — old credentials will lock the account — and affected individuals are being offered 12 months of credit monitoring.

This reaches well past Minnesota. Courts in at least eleven other states, the U.S. Virgin Islands and Ontario, Canada were caught in the same intrusion, which Thomson Reuters says happened inside its own environment rather than the courts' systems. Investigators are still working out what was taken.

CISA added two SonicWall SMA1000 vulnerabilities to its Known Exploited Vulnerabilities catalog on September 2, 2026, giving federal agencies just three days to act. SonicWall disclosed both as zero-days after finding them under active exploitation.

CVE-2026-83548 (CVSS 10.0, Critical) is a pre-authentication SSRF flaw in the Appliance Work Place interface. CVE-2026-83549 (CVSS 7.8, High) is an OS command injection in the Appliance Management Console that normally requires admin authentication. Chained, the SSRF supplies that access — turning the pair into unauthenticated remote code execution.

SonicWall says it has seen exploitation of both, which points to chaining, and that no public proof-of-concept exists. Affected models are the 6210, 7210, and 8200v; the fix is hotfix 12.4.3-03526 or 12.5.0-02952 and higher.

SMA1000 appliances handle enterprise remote access, making them high-value targets. CISA has flagged both under Binding Operational Directive 26-04, requiring forensic triage — not just patching. Audit admin activity, check for new accounts, and review outbound connections. If you find signs of compromise, SonicWall says to re-image, rotate all passwords, and reset TOTP tokens.

8.7 million people are at risk after hackers breached Manchester Airports Group (MAG) — operator of Manchester, Stansted, and East Midlands airports — and published the stolen data for free. FulcrumSec extorted MAG for an undisclosed sum, failed to get paid, and dumped half a terabyte in response: "every byte of it is pure PII," the gang wrote.

HaveIBeenPwned indexed the dump within a day — names, emails, phone numbers, IP addresses, and 108,000 vehicle plates among them. Unlike most leak sites, this one sits on the open internet rather than the dark web, so anyone can reach it.

Security researcher Kevin Beaumont warned that wealthy or high-profile people face particular risk: the files map where customers have been and where they're going next, including some 190,000 upcoming bookings. MAG says it contacted those travelers separately. Everyone else should expect scammers who know their phone number and car registration.

FulcrumSec says it got in the same way it hit Arup and Novo Nordisk: admin keys to Iterable, MAG's marketing platform, left in the airport websites' JavaScript. "Any of the millions of visitors to the site could have right-clicked 'inspect' and seen the keys," the gang wrote. MAG hasn't confirmed it.

A hacking group linked to Silver Fox (also known as Yinhu) is running a campaign that tricks users into downloading fake installers disguised as Razer, Microsoft Edge, Kaspersky, and other trusted tools. The sites look legitimate — until you open the ZIP file. Microsoft says the payload changes on every download, so hashes shift while filenames stay put.

Once installed, the malware doesn't switch Microsoft Defender off — it uses short-lived SYSTEM scheduled tasks to write sweeping scan exclusions, then deletes the tasks to cover its tracks. It also deletes shadow copies, stops Windows Update, and sets up recurring tasks that restart malicious code every 60 seconds.

Victims span healthcare, manufacturing, gaming, technology, logistics, government, and education, most of them the China-based operations of multinational organizations, or Chinese-speaking users. Microsoft assesses with moderate confidence that the activity is consistent with the reported Silver Fox campaign, and has stopped short of attributing it to a nation-state.

Turn on Tamper Protection — Microsoft says it blocks Defender exclusion and registry writes even when the payload is running as SYSTEM, which is exactly what this campaign depends on. And always download software directly from official publishers.

Chick-fil-A began notifying customers across 11 jurisdictions in late July after a credential-stuffing attack on its loyalty program between June 17 and 19. Thieves used usernames and passwords stolen from a third-party source to break into Chick-fil-A One accounts through the website and app. The company had concluded on July 13 that data may have been accessed.

Data that may have been accessed includes names, email addresses, membership numbers, Mobile Pay numbers, partial payment card digits, gift card balances, and QR codes. Customers who had saved more to their accounts may also have had their birth month and day, phone number, and address accessed.

Chick-fil-A calls it a limited number of accounts and hasn't given a total; filings show 2,182 in Texas and 39 in Massachusetts. It's the second credential-stuffing hit on Chick-fil-A One — an earlier one in 2023 reached more than 71,000 customers.

The company logged out affected users, removed stored payment methods, restored balances, and added rewards as compensation. Customers should reset their passwords and make them unique — reuse is what credential stuffing runs on — then check account activity. A law firm has been investigating a possible class action since early August.

A researcher known as MSNightmare — also tracked as Nightmare Eclipse and Chaotic Eclipse — has published a proof-of-concept called HardBreacher, claiming a local privilege-escalation zero-day in Kaspersky Endpoint Security on fully patched Windows 11 (version 25H2), running product version 14.0.0.504.

If real, a low-privileged user could write a DLL to System32 — normally off-limits — and seize a Kaspersky UI process, letting them stop the product, override its allow-or-block decisions, and destabilize the operating system. The researcher's previous drops have a mixed record: some stayed proof-of-concept, others ended up in active attacks.

Kaspersky says it has already addressed the issue, with the fix delivered through an automatic update — users can also trigger a database update manually. No CVE has been assigned. The PoC is unstable, error-prone, and requires multiple attempts.

Organizations should confirm their Kaspersky databases are current, review process telemetry, and avoid running the public code on production systems.

Norcross, Georgia is dealing with the fallout from a ransomware attack that hit some of the city's computer systems on August 1. Officials didn't go public until August 28 — nearly four weeks later — saying they responded as soon as the incident was detected, bringing in cybersecurity experts and notifying law enforcement.

Most city systems are back up and running, but some disruptions may continue as restoration work wraps up. The city is also rolling out new security measures.

Details are still limited given the ongoing investigation. Norcross hasn't said whether any resident or employee data was taken, nobody has claimed the attack, and the city hasn't disclosed a ransom demand. It says it will share more as things develop.
