Apple source code for a core component of iPhone's operating system has purportedly been leaked on GitHub, that could allow hackers and researchers to discover currently unknown zero-day vulnerabilities to develop persistent malware and iPhone jailbreaks. The source code appears to be for iBoot —the critical part of the iOS operating system that's responsible for all security checks and ensures a trusted version of iOS is loaded. In other words, it's like the BIOS of an iPhone which makes sure that the kernel and other system files being booted whenever you turn on your iPhone are adequately signed by Apple and are not modified anyhow. The iBoot code was initially shared online several months back on Reddit , but it just resurfaced today on GitHub (repository now unavailable due to DMCA takedown). Motherboard consulted some security experts who have confirmed the legitimacy of the code. However, at this moment, it is unclear if the iBoot source code is complete...

Apple has publicly made available its Private Cloud Compute (PCC) Virtual Research Environment (VRE), allowing the research community to inspect and verify the privacy and security guarantees of its offering. PCC, which Apple unveiled earlier this June, has been marketed as the "most advanced security architecture ever deployed for cloud AI compute at scale." With the new technology, the idea is to offload computationally complex Apple Intelligence requests to the cloud in a manner that doesn't sacrifice user privacy. Apple said it's inviting "all security and privacy researchers — or anyone with interest and a technical curiosity — to learn more about PCC and perform their own independent verification of our claims." To further incentivize research, the iPhone maker said it's expanding the Apple Security Bounty program to include PCC by offering monetary payouts ranging from $50,000 to $1,000,000 for security vulnerabilities identified in it. Th...

Apple has patched the security flaw in its Find My iPhone online service that may have allowed hackers to get access to a number of celebrities' private pictures leaked online. OVER 100 CELEBRITIES AFFECTED So far, I hope everybody have heard about probably the biggest digital exposure of personal nude photographs belonging to as many as 100 high-profile celebrities, including Jenny McCarthy, Kristin Dunst, Mary E Winstead, and the Oscar winning actress Jennifer Lawrence and Kate Upton. Initial reports suggested that the privacy breach of the celebrities’ iCloud accounts was made possible by a vulnerability in Find My iPhone feature that allowed hackers to allegedly take nude photographs of celebrities from their Apple iCloud backups. Anonymous 4chan users who claims to have grabbed images, posted some of the images to the “ b ” forum on notorious bulletin-board 4chan, where the owners demanded Bitcoin in exchange for a peek of the images. The anonymous 4c...

Apple iCloud users in China are not safe from the hackers — believed to be working for Chinese government — who are trying to wiretap Apple customers in the country. Great Fire , a reputed non-profit organization that monitors Internet censorship in China, claimed that the Chinese authorities have launched a nationwide Man in the Middle (MITM) campaign against users of Apple’s iCloud service, designed to steal users' login credentials and access private data. MAN-IN-THE-MIDDLE ATTACK The attacks on the iCloud service was first reported on Saturday and come as Apple begins the official rollout of its latest launched iPhone 6 and 6 Plus on the Chinese mainland. If we talk about less publicized but more danger, Man-in-the-Middle (MitM) attack is the most common one. By attempting MitM attack, a potential attacker could intercept users’ internet communication, steal sensitive information and even hijack sessions. ACCESS TO CREDENTIALS AND ALL PERSONAL DATA Usin...

Apple just patched an unpatched flaw that it patched previously but accidentally unpatched recently — did I confuse you? Let's try it again... Apple today finally released iOS 12.4.1 to fix a critical jailbreak vulnerability , like it or not, that was initially patched by the company in iOS 12.3 but was then accidentally got reintroduced in the previous iOS 12.4 update. For those unaware, roughly a week ago, an anonymous researcher who goes by the online alias "Pwn20wnd" released a free jailbreak for iOS 12.4 on GitHub that exploited a kernel vulnerability (CVE-2019-8605) that Apple patched in iOS 12.3 in May this year. However, the vulnerability accidentally got reintroduced in iOS 12.4 in July, making it easier for hackers to jailbreak updated Apple devices, including the iPhone XS, XS Max, and XR or the 2019 iPad Mini and iPad Air, running iOS 12.4 and iOS 12.2 or earlier. Now, Apple has released iOS 12.4.1 to re-patch the security issue that not only allow...

Hackers have a great start of new year 2015, giving a public threat to Apple’s online iCloud service. A hacker using the handle " Pr0x13 " has released a password-hacking tool to GitHub website that assures attackers to break into any iCloud account, potentially giving them free access to victims’ iOS devices. The tool, dubbed iDict , actually makes use of an exploit in Apple's iCloud security infrastructure to bypass restrictions and two-factor authentication security that prevents brute force attacks and keeps most hackers away from gaining access to users’ iCloud accounts. Yes, the brute force security flaw in Apple’s iCloud file storage service that was responsible for celebrity nude photos leak , including Kim Kardashian , Vanessa Hudgens , Jennifer Lawrence , Rihanna , Kristin Dunst and Kate Upton , late last year. Pr0x13 claims iDict to be a "100 percent" effective and simple to use method of cracking individual iCloud account login credentials. So, t...

In cybersecurity, the smallest crack can lead to the biggest breaches. A leaked encryption key, an unpatched software bug, or an abandoned cloud storage bucket—each one seems minor until it becomes the entry point for an attack. This week, we’ve seen cybercriminals turn overlooked weaknesses into major security threats, proving once again that no system is too small to be targeted. The question isn’t whether attackers will find a way in—it’s whether you’ll be prepared when they do. Let’s break down what you need to know. ⚡ Threat of the Week Microsoft Warns of Attacks Exploiting ASP.NET Machine Keys — Threat actors are exploiting publicly disclosed ASP.NET machine keys to inject and execute malicious code responsible for launching the Godzilla post-exploitation framework. Microsoft said it has identified over 3,000 publicly disclosed keys that could be used for these types of attacks dubbed ViewState code injection. The company also said it removed key-related artifacts from ...

As a punishment announced last October, Google will no longer trust SSL/TLS certificate authorities WoSign and its subsidiary StartCom with the launch of Chrome 61 for not maintaining the "high standards expected of CAs." The move came after Google was notified by GitHub's security team on August 17, 2016, that Chinese Certificate Authority WoSign had issued a base certificate for one of GitHub's domains to an unnamed GitHub user without authorization. After this issue had been reported, Google conducted an investigation in public as a collaboration with Mozilla and the security community, which uncovered several other cases of WoSign misissuance of certificates. As a result, the tech giant last year began limiting its trust of certificates backed by WoSign and StartCom to those issued before October 21st, 2016 and has been removing whitelisted hostnames over the course of several Chrome releases since Chrome 56. Now, in a Google Groups post published ...

Security and IT teams are routinely forced to adopt software before fully understanding the security risks. And AI tools are no exception. Employees and business leaders alike are flocking to generative AI software and similar programs, often unaware of the major SaaS security vulnerabilities they're introducing into the enterprise. A February 2023  generative AI survey of 1,000 executives  revealed that 49% of respondents use ChatGPT now, and 30% plan to tap into the ubiquitous generative AI tool soon. Ninety-nine percent of those using ChatGPT claimed some form of cost-savings, and 25% attested to reducing expenses by $75,000 or more. As the researchers conducted this survey a mere three months after ChatGPT's general availability, today's ChatGPT and AI tool usage is undoubtedly higher.  Security and risk teams are already overwhelmed protecting their SaaS estate (which has now become the operating system of business) from common vulnerabilities such as misconfigura...

A security researcher has discovered a critical vulnerability in the latest version of Apple's OS X Yosemite  that could allow anyone to obtain unrestricted root user privileges with the help of code that fits in a tweet. The privilege-escalation vulnerability initially reported on Tuesday by German researcher Stefan Esser , could be exploited by to circumvent security protections and gain full control of Mac computers. The most worrying part is that this critical vulnerability is yet to be fixed by Apple in the latest release of its operating system. This could make it easier for hackers to surreptitiously infect Macs with rootkits and other types of persistent malware. Thanks to an environment variable DYLD_PRINT_TO_FILE Apple added to the code of OS X 10.10 Yosemite. Apple Mac OS X Vulnerability Gives Full Control of your Mac This environment variable specifies where in the file system an operating system component called the OS X dynamic linker dyld ...

Apple on Wednesday expanded the availability of iOS 18.7.7 and iPadOS 18.7.7 to a broader range of devices to protect users from the risk posed by a recently disclosed exploit kit known as DarkSword . "We enabled the availability of iOS 18.7.7 for more devices on April 1, 2026, so users with Automatic Updates turned on can automatically receive important security protections from web attacks called DarkSword," the company said. "The fixes associated with the DarkSword exploit first shipped in 2025." The update is available for the following devices - iPhone XR, iPhone XS, iPhone XS Max, iPhone 11 (all models), iPhone SE (2nd generation), iPhone 12 (all models), iPhone 13 (all models), iPhone SE (3rd generation), iPhone 14 (all models), iPhone 15 (all models), iPhone 16 (all models), and iPhone 16e iPad mini (5th generation - A17 Pro), iPad (7th generation - A16), iPad Air (3rd - 5th generation), iPad Air 11-inch (M2 - M3), iPad Air 13-...

The kernel exploit for two security vulnerabilities used in the recently uncovered Apple iOS exploit kit known as Coruna is an updated version of the same exploit that was used in the Operation Triangulation campaign back in 2023, according to new findings from Kaspersky. "When Coruna was first reported, the public evidence wasn't sufficient to link its code to Triangulation — shared vulnerabilities alone don't prove shared authorship," Boris Larin, principal security researcher at Kaspersky GReAT, told The Hacker News in a statement. "Coruna is not a patchwork of public exploits; it is a continuously maintained evolution of the original Operation Triangulation framework. The inclusion of checks for recent processors like the M3 and newer iOS builds shows that the original developers have actively expanded this codebase. What began as a precision espionage tool is now deployed indiscriminately." Coruna was first documented by Google and iVerify earli...

In cybersecurity, precision matters—and there’s little room for error. A small mistake, missed setting, or quiet misconfiguration can quickly lead to much bigger problems. The signs we’re seeing this week highlight deeper issues behind what might look like routine incidents: outdated tools, slow response to risks, and the ongoing gap between compliance and real security. For anyone responsible for protecting systems, the key isn’t just reacting to alerts—it’s recognizing the larger patterns and hidden weak spots they reveal. Here’s a breakdown of what’s unfolding across the cybersecurity world this week. ⚡ Threat of the Week NCA Arrests for Alleged Scattered Spider Members — The U.K. National Crime Agency (NCA) announced that four people have been arrested in connection with cyber attacks targeting major retailers Marks & Spencer, Co-op, and Harrods. The arrested individuals include two men aged 19, a third aged 17, and a 20-year-old woman. They were apprehended in the West...

Security researchers are warning of "a trove of sensitive information" leaking through urlscan.io, a website scanner for suspicious and malicious URLs. "Sensitive URLs to shared documents, password reset pages, team invites, payment invoices and more are publicly listed and searchable," Positive Security co-founder, Fabian Bräunlein,  said  in a report published on November 2, 2022. The Berlin-based cybersecurity firm said it started an investigation in the aftermath of a  notification  sent by GitHub in February 2022 to an unknown number of users about sharing their usernames and private repository names (i.e.,  GitHub Pages URLs ) to urlscan.io for metadata analysis as part of an automated process. Urlscan.io, which has been described as a  sandbox for the web , is  integrated  into several security solutions  via its API . "With the type of integration of this API (for example via a security tool that scans every incoming email ...

Thursday. Another week, another batch of things that probably should've been caught sooner but weren't. This one's got some range — old vulnerabilities getting new life, a few "why was that even possible" moments, attackers leaning on platforms and tools you'd normally trust without thinking twice. Quiet escalations more than loud zero-days, but the kind that matter more in practice anyway. Mix of malware, infrastructure exposure, AI-adjacent weirdness, and some supply chain stuff that's... not great. Let's get into it. Resilient hybrid botnet surge Phorpiex Botnet Detailed A new variant of the botnet known as Phorpiex (aka Trik) has been observed, using a hybrid communication model that combines traditional C2 HTTP polling with a peer-to-peer (P2P) protocol over both TCP and UDP to ensure operational continuity in the face of server takedowns. The malware acts as a conduit for encrypted payloads, ma...

The United States National Security Agency (NSA) has released a network security tool for Government and the private sectors to help secure their networks against cyber attacks. Dubbed Systems Integrity Management Platform (SIMP) , the tool is now publicly available on the popular source code sharing website GitHub . According to an official release from NSA, SIMP makes it easier for government organizations and the private sector to "fortify their networks against cyber threats." SIMP aims at providing a reasonable combination of security compliance and operational flexibility , keeping networked systems compliant with security standards and requirements. It is considered to be a critical part of a layered, "defence-in-depth" approach to information security. " By releasing SIMP, the agency seeks to reduce duplication of effort and promote greater collaboration within the community: The wheel would not have to be reinvented for every organiza...

Google introduced a new security tool to help developers detect bugs and security glitches in the network traffic security that may leave passwords and other sensitive information open to snooping. The open source tool, dubbed as Nogotofail , has been launched by the technology giant in sake of a number of vulnerabilities discovered in the implementation of the transport layer security, from the most critical Heartbleed bug in OpenSSL to the Apple's gotofail bug to the recent POODLE bug in SSL version 3. The company has made the Nogotofail tool available on GitHub, so that so anyone can test their applications, contribute new features to the project, provide support for more platforms, and help improve the security of the internet. Android security engineer Chad Brubaker said that the Nogotofail main purpose is to confirm that internet-connected devices and applications aren't vulnerable to transport layer security (TLS) and Secure Sockets Layer (SSL) encry...
