Apple has patched a CoreGraphics zero-day after warning that attackers may already have used the bug to compromise a small number of carefully chosen targets. The vulnerability, tracked as CVE-2026-86950, is an out-of-bounds write flaw in CoreGraphics, Apple's framework for handling graphics across its operating systems. According to Apple's advisory, processing a maliciously crafted file could allow an attacker to execute arbitrary code on a vulnerable device. The fruity vendor said it addressed the problem with improved bounds checking, though the bug appears to have made it out into the wild before Apple could squash it. "Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 27," the company said. As is customary when Cupertino encounters the sort of security bug somebody has apparently found useful, further details are thin on the ground. Apple didn't say who was targeted, how many people were affected, who was behind the attacks, or exactly how the vulnerability was being exploited. However, its choice of words suggests this wasn't a bug being exploited indiscriminately across the internet, and raises the possibility that it was used as part of a targeted spyware campaign. Meta Product Security reported CVE-2026-86950 to Apple, but neither Apple's advisory nor Meta has provided further technical details on how the flaw was discovered or the attacks in which it was allegedly used. The fix landed on Monday in iOS 26.7.1 and iPadOS 26.7.1. Apple lists affected devices receiving the update as the iPhone 11 and later, iPad Pro 12.9-inch (third generation and later), iPad Pro 11-inch (first generation and later), iPad Air (third generation and later), iPad (eighth generation and later), and iPad mini (fifth generation and later). Apple specifically says the attacks hit devices running versions of iOS before iOS 27, though it hasn't said exactly which older releases were targeted. The flaw adds another entry to Apple's growing collection of vulnerabilities caught being abused before users had a patch, with CVE-2026-86950 landing as the seventh zero-day fixed by the company this year. For anyone still running the affected releases, that leaves the usual less-than-thrilling security advice: install the update rather than waiting to find out exactly what an "extremely sophisticated attack" looks like. ®

Two former leaders of IBM's X-Force Red team have launched RemoteThreat, an offensive cybersecurity startup backed by $7 million in pre-seed funding. CEO Chris Thompson and CTO Shawn Jones say the company's platform uses AI to plan, execute, and adapt offensive cyber operations, extending beyond the continuous penetration testing and vulnerability detection offered by other automated security tools. Thompson and Jones previously ran X-Force Red, where their team was hired to test nuclear power plants, critical infrastructure, and major banks. In May 2024, Thompson told The Register how X-Force used AI to break into a semiconductor manufacturer's network in eight hours. The pair subsequently created Offensive AI Con, an invitation-only research event whose second edition is scheduled for early October. "We're looking at how noisy but very capable frontier models are right now, and we started to think: What happens when they can do what we can do as one of the best groups of red-teamers in the world?" Thompson told The Register in an interview. He said the concern was that AI could produce custom malware approaching the quality used by state-sponsored attackers, then deploy it at unprecedented speed and scale. RemoteThreat's 15 employees include senior operators, security researchers, engineers, and malware developers from X-Force Adversary Services, Mandiant, SpecterOps, Dreadnode, Bugcrowd, Microsoft, defense contractors, and government agencies. RemoteThreat says its platform gives defenders and government operators access to the same speed and scale that AI may offer their adversaries. According to the startup, its customers already include a major bank, a securities exchange operator, a large US healthcare company, and a leading AI lab. "We're focused on preparing these Fortune 500 organizations to better simulate this nation-state level of attack," Thompson said. "And then on the flip side, provide the government with the tooling to target their adversaries as quickly as possible." RemoteThreat describes its platform as eight connected systems covering mission planning, command and control, implants, initial access, advanced attack capabilities, obfuscation, analysis, and AI-assisted operations. Given the obvious potential for misuse, RemoteThreat says access is restricted to vetted enterprises, defense contractors, and US government customers. The platform uses small, purpose-built models for some tasks. Customers can also connect models from OpenAI or Anthropic, or use an open-weight alternative, giving the chosen LLM access to what Thompson described as "1,000 tools that we've built from scratch." The platform can be operated by either humans or AI agents. Customers can "drive a lot of this testing from your Codex terminal instead of having to log into our website, for example," Thompson said. RemoteThreat says its capabilities can run within the complete platform or be integrated as components of partners' products. It has teamed up with Talon Defense, which supplies AI and cyber technology to national security, defense, and intelligence customers. RemoteThreat has also partnered with the Nakasone Group, the national security advisory firm founded by retired US Army Gen. Paul Nakasone, former director of the National Security Agency and commander of US Cyber Command. Nakasone is also a strategic adviser to the startup. The launch comes as Washington seeks a larger private-sector role in offensive cyber operations. The US Cyber Strategy published in March calls for closer cooperation with industry on defensive and offensive missions. An August presidential memorandum goes further, ordering the creation of a program through which vetted US companies may conduct cyber operations against foreign cybercrime groups under federal direction and oversight. RemoteThreat also says it has joined US Special Operations Command's Special Operations Forces Rapid Acquisition Consortium for Emerging Requirements, or SOF RACER, which provides a route for supplying capabilities to special operations forces. Thompson expects the government to make greater use of commercially developed offensive cyber products, both to support existing mission teams and to pursue cybercriminal groups. "It's a bit of a gold rush in this space because this is the first time, across every major program, the government is being pushed to work with the commercial sector," he said. RemoteThreat is positioning itself to supply the picks and shovels – albeit ones capable of breaking into somebody else's network. ®

The cyber criminal behind JadePuffer, the first known agentic ransomware infection reported over the summer, has also used stolen Azure identities to conduct destructive attacks on cloud storage and other resources, according to Microsoft. In July, Sysdig threat hunters uncovered JadePuffer, the first-ever documented agentic ransomware infection in which an LLM drove the entire extortion operation, from gaining initial access to compromising a production database server and destroying data. Now Redmond says that it has detected the same attacker, which it tracks as Storm-3168, up to new mischief. Over an 18-hour period in early June, Storm-3168 compromised two service principals and used these machine identities for “extensive Azure-focused resource destruction” and “cloud credential collection that could be used to facilitate future exfiltration,” researchers Yossi Weizman and Tushar Mudi wrote on Friday. The two compromised service principals belonged to the same cloud tenant. The crims used one of them to conduct reconnaissance and resource discovery, and the other to carry out destructive operations and credential collection. The Redmond researchers don’t know how Storm-3168 initially hijacked the service principals, but noted that an employee of the same organization previously exposed client IDs, client secrets, and tenant IDs in plaintext in a public GitHub issue. “Since the beginning of this year, we also observed repeated probing from Storm-3168 linked infrastructure against multiple Azure App services for different customers,” the duo wrote. The entire attack took about 18 hours, with the discovery piece lasting about 15 hours and 30 minutes. During this time, the compromised service principal collected detailed information about Azure Virtual Machines, subscriptions, resource groups, and resources, completing more than 300 successful read operations. “This breadth of activity would give the threat actor visibility across the organization’s Azure environment,” Weizman and Mudi wrote. About 90 minutes after the first machine identity began hoovering up Azure information, the second compromised service principal started its work, reading Azure VMs and resource groups across two subscriptions in just five seconds. According to Redmond, both of these service principals used Storm-3168 linked infrastructure, the same network fingerprint, and the user agent python-requests/2.34.2. About 16 hours after the initial target reads, the second service principal successfully discovered Azure App Service configuration stores - it was likely looking for exposed credentials, we’re told - and unsuccessfully attempted to find Azure OpenSearch resources. Seventy seconds after this, it also attempted a ListKey operation against a non-existent storage account. Then, the destruction began. During this part of the operation, the compromised service principal attempted more than 150 destructive or credential-stealing attempts in 35 minutes. The destructive activity only lasted about 7 minutes with the machine identity attempting to delete more than 100 Azure Storage accounts. Most of these were successful, although Azure resource locks and storage account-level deletion did block a few. Additionally, the attacker deleted an Azure Key Vault, Function App, App service plan, all of which belonged to the same resource group and likely supported the Function app. “The same service principal also attempted to delete multiple Azure SQL databases in parallel with the storage account deletions mentioned earlier, but every deletion attempt failed because it used an unsupported API version for the Azure SQL database resource type,” Weizman and Mudi wrote. About 28 minutes after the destruction ended, “the same service principal made an inventory request for Azure Storage Accounts and sent more than 30 successful ListKeys requests, asking ARM to return each storage account’s access keys,” they added. “These storage accounts included Azure Site Recovery related storage accounts.” Multiple unsuccessful deletion attempts were also made against Azure Site Recovery locks and Azure Backup protection locks protecting storage accounts. According to Microsoft, the destructive activity - deleting numerous Azure resources, while also targeting backup and recovery-related resources - seems to indicate that Storm-3168 was setting up a ransomware attack. “Taken together, the resource destruction, attempts to interfere with recovery mechanisms, and collection of credentials that could provide access to data are consistent with tactics that can support ransomware and extortion operations,” Weizman and Mudi wrote. However, no ransom note was ever sent. "We did not observe a ransom note or confirm successful data exfiltration in the activity described here," they wrote. ®
