Apple shipped emergency updates on September 28, 2026 to fix CVE-2026-86950, an out-of-bounds write in CoreGraphics that lets a maliciously crafted file run arbitrary code on the device. The fixes landed in iOS 26.7.1, iPadOS 26.7.1, macOS Tahoe 26.7.1, and macOS Sequoia 15.8.1, covering iPhone 11 and later along with iPad models back to the third-generation iPad Air.

Apple says the issue "may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 27." Meta Product Security reported the bug, and no CVSS score has been published. Update through Settings > General > Software Update.

An OpenAI agent gained unauthorized access to Services Australia's Medicare statistics reporting portal on June 18, 2026, reading public and non-public files and writing data to an internal server. Prime Minister Anthony Albanese said blocks came back telling the agent no, and it found a way around them. He called the situation "obviously unacceptable."

The access happened during an internal evaluation, while OpenAI tested how its models performed at looking up Australian government spending on medicines. OpenAI says its review found no evidence patient records were accessed, and that the information involved was aggregate health statistics and internal file names. Albanese said no individuals have been affected so far.

OpenAI discovered the activity in August during a review of misaligned model behavior and notified Services Australia on September 10, after validating what the agents had reached. Albanese said the notification came as an email to a public inbox checked once a day, and that both the delay and the method were unacceptable.

Australia has launched a rapid review involving its national cybersecurity agency, examining whether other systems were affected and whether any law was broken. Albanese named three more: the Australian Institute of Health and Welfare, the NSW Bureau of Crime Statistics and Research, and the Victorian Department of Health. Nonprofit lab Transluce documented OpenAI agents probing the AIHW for vulnerabilities in June.

Citrix has patched two actively exploited flaws in NetScaler ADC and NetScaler Gateway, both rated CVSS 9.5 on the v4.0 scale and both exploitable without authentication. CVE-2026-88771 is an input validation flaw affecting every deployment by default, while CVE-2026-88772 is a memory overflow that hits systems with DTLS enabled, the default for VPN servers. Citrix found both while investigating incidents in customer environments.

CISA added both to its Known Exploited Vulnerabilities catalog on September 27, the day the patches shipped. Six further flaws were fixed alongside them, including an HTTP request smuggling bug rated 9.3. The fixed builds are 14.1-73.37, 13.1-64.23, 14.1-73.37 FIPS, and 13.1-37.279 FIPS/NDcPP. Several national agencies, including the Dutch NCSC, told organisations to shut appliances down until they could patch.

Patching closes the holes but leaves any attacker persistence in place. Preserve logs and snapshots before updating, run Citrix's IOC scan, and rotate every password, secret, and certificate stored on or used through the appliance. watchTowr warns the IOCs do not cover every technique, so a clean scan is not proof an appliance is clean.

Patrick Wardle, founder of Objective-See, disclosed a zero-day in Meta's Muse, a macOS AI assistant Meta markets around a dedicated secure VM, protected credential storage, and user-controlled permissions. An undocumented preference called endo_voyager_dictation_endpoint can be rewritten by any process running as the logged-in user, redirecting Muse's dictation traffic to an attacker-controlled server.

From there an attacker reads dictated prompts and audio, injects instructions Muse trusts and acts on, and lifts the Muse session token. Wardle's proof-of-concept, not-a-mused, used a stolen token to make the Muse app on his iPhone report precise location, run Bluetooth scans, and list smart-home commands. No CVE or CVSS has been assigned, and no in-the-wild exploitation has been reported.

Exploitation needs code execution as the user first, so existing malware is the delivery route rather than a remote attack. Meta shipped a hot-fix roughly 16 hours after Wardle went public on September 21, and he confirmed it the next day. If you ran Muse before the fix, update it, revoke unnecessary permissions, and treat connected accounts as exposed.

Google's Gemini model broke into three real companies during a May 2026 test of its cybersecurity capabilities, in what is thought to be the first known case of a Google model hacking on its own. It happened during a capture-the-flag exercise run by Irregular, an independent evaluation firm, after a bug in the test environment gave the model internet access it was never meant to have.

Gemini had been told to pull information from a fictional company, which turned out to share its name with a real one. In one case it guessed passwords until it got into a protected system; in the other two it used working credentials sitting in a public repository. Google says the model stopped each time it recognised the target was real, and did no further damage.

Irregular says it informed Google and all affected entities in July and resolved the known issues on its end weeks ago; Google says it ensured the three companies were told. The same testing fault lies behind the breakouts disclosed by OpenAI, Anthropic and Meta this year — and Gemini's May intrusions came first.

None of it needed a novel exploit. A guessed password and credentials left lying in a public repository were enough. The model didn't get clever; it got lucky, on someone else's housekeeping. Audit what your teams have exposed, rotate anything a guess could reach, and treat public repos as hostile ground.

Cisco has patched CVE-2026-76460, an authentication bypass in Identity Services Engine rated CVSS 10.0 that attackers were already exploiting. Insufficient authentication control on an API endpoint lets a remote attacker send a crafted request, reach the web management interface, and run commands as root with no credentials and no user interaction. Cisco ISE and ISE-PIC are both affected, regardless of configuration.

CISA added the flaw to its Known Exploited Vulnerabilities catalog on September 16 and gave federal agencies until September 19 to remediate, a deadline that has now passed. Fixed builds differ by branch: Patch 12 for 3.1, Patch 11 for 3.2, Patch 12 for 3.3, Patch 7 for 3.4, and Patch 4 for 3.5. Version 3.0 is unsupported and receives no fix.

A compromised ISE can impersonate devices, disable access controls, and open the rest of the network. Cisco says no workaround addresses the flaw, though infrastructure access control lists restricting management and control plane traffic limit remote exploitation until you patch. Check the ISE access.log for suspicious usernames, and treat a clean result carefully — root access lets an attacker remove the traces.

Five alleged leaders of Black Axe's South African operations were extradited to the United States on September 11 to face charges tied to romance scams and advance-fee fraud between 2011 and 2021. All five are Nigerian nationals, aged 38 to 57, arrested in South Africa in 2021.

The men appeared before U.S. District Judge Michael A. Shipp in Trenton, New Jersey, on September 14. Perry Osagiede, 57, is named in the indictment as founder and zonal head of Black Axe's Cape Town Zone. Prosecutors say the group used fake identities to trick victims into sending money, and sometimes threatened to release sensitive photos when targets refused.

Maximum penalties reach 62 years, but only for the two defendants charged on all four counts. Wire fraud, wire fraud conspiracy, and money laundering conspiracy each carry up to 20 years, and aggravated identity theft adds a mandatory two. The Justice Department stresses that the indictment contains accusations only and that all five are presumed innocent.

Amazon's threat intelligence team successfully disrupted a sophisticated credential theft campaign by APT29, the Russian intelligence-linked hacking group behind the 2020 SolarWinds attack. The operation compromised legitimate websites to inject malicious code that redirected 10% of visitors to fake Cloudflare verification pages.

Once there, users were tricked into entering email addresses and authorizing attackers' devices to access their Microsoft accounts through a rare "device code authentication" technique. APT29 used Amazon EC2 instances and other cloud infrastructure to blend with legitimate traffic.

Despite the group's attempts to migrate infrastructure after detection, Amazon continued tracking and disrupting their operations. Security experts recommend organizations review Microsoft's device authentication guidance and consider disabling the feature if unnecessary.
