Hacker Releases 'Unpatchable' Jailbreak For All iOS Devices, iPhone 4s to iPhone X

September 27, 2019Mohit Kumar
An iOS hacker and cybersecurity researcher today publicly released what he claimed to be a "permanent unpatchable bootrom exploit," in other words, an epic jailbreak that works on all iOS devices ranging from iPhone 4s (A5 chip) to iPhone 8 and iPhone X (A11 chip). Dubbed Checkm8, the exploit leverages unpatchable security weaknesses in Apple's Bootrom (SecureROM), the first significant code that runs on an iPhone while booting, which, if exploited, provides greater system-level access. "EPIC JAILBREAK: Introducing checkm8 (read "checkmate"), a permanent unpatchable bootrom exploit for hundreds of millions of iOS devices," said axi0mX while announcing the publicly release of the exploit on Twitter. The new exploit came exactly a month after Apple released an emergency patch for another critical jailbreak vulnerability that works on Apple devices including the iPhone XS, XS Max, and XR and the 2019 iPad Mini and iPad Air, running iOS 12.4 and i

Attention Android users! Millions of Android devices are vulnerable to hackers and intelligence agencies once again – Thanks to a newly disclosed Android Stagefright Exploit . Yes, Android Stagefright vulnerability is Back… …and this time, the Stagefright exploit allows an attacker to hack Android smartphones in 10 seconds just by tricking users into visiting a hacker's web page that contains a malicious multimedia file. A group of security researchers from Israel-based research firm NorthBit claimed it had successfully exploited the Stagefright bug that was emerged in Android last year and described as the "worst ever discovered" . The new Stagefright exploit, dubbed Metaphor , is detailed in a research paper [ PDF ] that guides bad guy, good guy as well as government spying agencies to build the Stagefright exploit for themselves. Just yesterday, we reported about critical vulnerabilities in Qualcomm Snapdragon chip that could be exploited
Researchers Fingerprint Exploit Developers Who Help Several Malware Authors

Researchers Fingerprint Exploit Developers Who Help Several Malware Authors

October 02, 2020Ravie Lakshmanan
Writing advanced malware for a threat actor requires different groups of people with diverse technical expertise to put them all together. But can the code leave enough clues to reveal the person behind it? To this effect, cybersecurity researchers on Friday detailed a new methodology to identify exploit authors that use their unique characteristics as a fingerprint to track down other exploits developed by them. By deploying this technique, the researchers were able to link 16 Windows local privilege escalation (LPE) exploits to two zero-day sellers "Volodya" (previously called "BuggiCorp") and "PlayBit" (or "luxor2008"). "Instead of focusing on an entire malware and hunting for new samples of the malware family or actor, we wanted to offer another perspective and decided to concentrate on these few functions that were written by an exploit developer," Check Point Research's Itay Cohen and Eyal Itkin noted. Fingerprinting an

Hackers Selling Unpatched Microsoft Windows Zero-Day Exploit for $90,000

June 03, 2016Swati Khandelwal
How much a Windows zero-day exploit that affects all versions of Windows operating system costs on the black market? It's $95,000, at least, for the one recently spotted by security researchers. Researchers from Trustwave's SpiderLabs team have uncovered a zero-day exploit on Russian underground malware forum exploit.in, affecting all versions of Microsoft Windows OS from Windows 2000 all the way up to a fully patched version of Windows 10. The zero-day exploit for the previously unknown vulnerability in " every version " of Windows is openly sold for $90,000 ( over £62,000 ). The security team originally discovered the zero-day exploit last month when the firm saw its ad on a Russian hacking forum for $95,000. However, the price has now been dropped to $90,000. The zero-day vulnerability in question claims to be a Local Privilege Escalation (LPE) bug in Windows that offers admin access to run malicious code on a victim's PC and is less dangerous th

Angler Exploit Kit Uses Domain Shadowing technique to Evade Detection

March 05, 2015Swati Khandelwal
The world's infamous Angler Exploit Kit has become the most advanced, much more powerful and the best exploit kit available in the market, beating the infamous BlackHole exploit kit , with a host of exploits including zero-days and a new technique added to it. Angler Exploit Kit's newest technique is dubbed "Domain Shadowing" which is considered to be the next evolution of online crime. Domain Shadowing, first appeared in 2011, is the process of using users domain registration logins to create subdomains. WHAT IS DOMAIN SHADOWING ? With the help of Domain Shadowing technique used in a recent Angler campaign, attackers are stealing domain registrant credentials to create tens of thousands of sub-domains that are used in hit-and-run style attacks in order to either redirect victims to the attack sites, or serve them malicious payloads. Security researcher Nick Biasini of Cisco's Talos intelligence team analysed the campaign and said the "massive&qu

Firefox Zero-Day Exploit to Unmask Tor Users Released Online

November 29, 2016Swati Khandelwal
Hackers are actively exploiting a zero-day vulnerability in Firefox to unmask Tor Browser users, similar to what the FBI exploited during an investigation of a child pornography site. Tor (The Onion Router) is an anonymity software that not only provides a safe heaven to human rights activists, journalists, government officials, but also is a place where drugs, assassins for hire, child pornography, and other illegal activities has allegedly been traded. A Javascript zero-day exploit currently being actively exploited in the wild is designed to remotely execute malicious code on the Windows operating system via memory corruption flaw in Firefox web browser. The exploit code was publicly published by an admin of the SIGAINT privacy-oriented public email service on the Tor-Talk mailing list. The mailing list message reveals that the zero-day exploit affecting Firefox is currently being exploited against Tor Browser users by unknown attackers to leak the potentially identifyi

Chinese Hacker Publishes PoC for Remote iOS 12 Jailbreak On iPhone X

January 23, 2019Wang Wei
Here we have great news for all iPhone Jailbreak lovers and concerning one for the rest of iPhone users. A Chinese cybersecurity researcher has today revealed technical details of critical vulnerabilities in Apple Safari web browser and iOS that could allow a remote attacker to jailbreak and compromise victims' iPhoneX running iOS 12.1.2 and before versions. To do so, all an attacker needs to do is trick iPhoneX users into opening a specially crafted web page using Safari browser, that's it. However, finding flaws and creating a working exploit to carry out such attacks is not as easy as it may sound for every iOS hacker. Discovered by security researcher Qixun Zhao of Qihoo 360's Vulcan Team, the exploit takes advantage of two security vulnerabilities that were first demonstrated at TianfuCup hacking contest held in November last year and then was later responsibly reported to the Apple security team. Zhao today released some details of and a proof-of-concep

Kernel Exploit for Sony PS4 Firmware 4.05 Released, Jailbreak Coming Soon

December 27, 2017Mohit Kumar
Wishing you all a very 'belated' Merry Christmas. This holiday season Santa has a very special gift for all PlayStation gamers. Developer SpecterDev finally released a fully-functional much-awaited kernel exploit for PlayStation 4 (firmware 4.05) today—almost two months after Team Fail0verflow revealed the technical details of it. Now available on Github , dubbed "namedobj," the kernel exploit for the PlayStation 4 on 4.05FW allows users to run arbitrary code on the gaming console, enabling jailbreaking and kernel-level modifications to the system. Although PS4 kernel exploit does not include Jailbreak code, others can develop a full jailbreak exploit using it. Jailbreaking allows users to run custom code on the console and install mods, cheats, third-party applications, and games that are typically not possible because of the anti-piracy mechanisms implicated on the Sony PlayStation. "This release, however, does not contain any code related to def
Unpatched VirtualBox Zero-Day Vulnerability and Exploit Released Online

Unpatched VirtualBox Zero-Day Vulnerability and Exploit Released Online

November 08, 2018Mohit Kumar
An independent exploit developer and vulnerability researcher has publicly disclosed a zero-day vulnerability in VirtualBox —a popular open source virtualization software developed by Oracle—that could allow a malicious program to escape virtual machine (guest OS) and execute code on the operating system of the host machine. The vulnerability occurs due to memory corruption issues and affects Intel PRO / 1000 MT Desktop (82540EM) network card (E1000) when the network mode is set to NAT (Network Address Translation). The flaw is independent of the type of operating system being used by the virtual and host machines because it resides in a shared code base. VirtualBox Zero-Day Exploit and Demo Video Released Sergey Zelenyuk published Wednesday a detailed technical explanation of the zero-day flaw on GitHub, which affects all current versions (5.2.20 and prior) of VirtualBox software and is present on the default Virtual Machine (VM) configuration. According to Zelenyuk, t
Bad Rabbit Ransomware Uses Leaked 'EternalRomance' NSA Exploit to Spread

Bad Rabbit Ransomware Uses Leaked 'EternalRomance' NSA Exploit to Spread

October 27, 2017Mohit Kumar
A new widespread ransomware worm, known as " Bad Rabbit ," that hit over 200 major organisations, primarily in Russia and Ukraine this week leverages a stolen NSA exploit released by the Shadow Brokers this April to spread across victims' networks. Earlier it was reported that this week's crypto-ransomware outbreak did not use any National Security Agency-developed exploits, neither EternalRomance nor EternalBlue , but a recent report from Cisco's Talos Security Intelligence revealed that the Bad Rabbit ransomware did use EternalRomance exploit. NotPetya ransomware (also known as ExPetr and Nyetya) that infected tens of thousands of systems back in June also leveraged the EternalRomance exploit , along with another NSA's leaked Windows hacking exploit EternalBlue, which was used in the WannaCry ransomware outbreak. Bad Rabbit Uses EternalRomance SMB RCE Exploit Bad Rabbit does not use EternalBlue but does leverage EternalRomance RCE exploit to spread

Cisco Exploit Leaked in NSA Hack Modifies to Target Latest Version of Firewalls

August 24, 2016Mohit Kumar
Recently released NSA exploit from " The Shadow Brokers " leak that affects older versions of Cisco System firewalls can work against newer models as well. Dubbed ExtraBacon , the exploit was restricted to versions 8.4.(4) and earlier versions of Cisco's Adaptive Security Appliance (ASA) – a line of firewalls designed to protect corporate, government networks and data centers. However, the exploit has now been expanded to 9.2.(4) after researchers from Hungary-based security consultancy SilentSignal were able to modify the code of ExtraBacon to make it work on a much newer version of Cisco's ASA software. Both Cisco and Fortinet have confirmed their firewalls are affected by exploits listed in the Shadow Brokers cache that contained a set of " cyber weapons " stolen from the Equation Group . The Equation Group is an elite hacking group tied to the NSA's offensive Tailored Access Operations (TAO) and linked to the previous infamous Regin and S

Hacking Team Flash Zero-Day Linked to Cyber Attacks on South Korea and Japan

July 09, 2015Wang Wei
The corporate data leaked in the recent cyber attack on the infamous surveillance software firm Hacking Team has revealed that the Adobe Flash zero-day (CVE-2015-5119) exploit has already been added to several exploit kits. Security researchers at Trend Micro have discovered evidences of the Adobe Flash zero-day (CVE-2015-5119) exploit being used in a number of exploit kits before the vulnerability was publicly revealed in this week's data breach on the spyware company. The successful exploitation of the zero-day Flash vulnerability could cause a system crash, potentially allowing an attacker to take full control of the affected system. Adobe Flash Zero-Day Targeted Japan and Korea According to the researchers, the zero-day exploit, about which the rest of the world got access on Monday, was apparently used in limited cyber attacks on South Korea and Japan . "In late June, [Trend Micro] learned that a user in Korea was the attempted target of various

New Drammer Android Hack lets Apps take Full control (root) of your Phone

October 24, 2016Swati Khandelwal
Earlier last year, security researchers from Google's Project Zero outlined a way to hijack the computers running Linux by abusing a design flaw in the memory and gaining higher kernel privileges on the system. Now, the same previously found designing weakness has been exploited to gain unfettered "root" access to millions of Android smartphones, allowing potentially anyone to take control of affected devices. Researchers in the VUSec Lab at Vrije Universiteit Amsterdam have discovered a vulnerability that targets a device's dynamic random access memory (DRAM) using an attack called Rowhammer . Although we are already aware of the Rowhammer attack , this is the very first time when researchers have successfully used this attack to target mobile devices. What is DRAM Rowhammer Attack? The Rowhammer attack against mobile devices is equally dangerous because it potentially puts all critical data on millions of Android phones at risk, at least until a secu

Hacker Discloses New Windows Zero-Day Exploit On Twitter

October 24, 2018Swati Khandelwal
A security researcher with Twitter alias SandboxEscaper—who two months ago publicly dropped a zero-day exploit for Microsoft Windows Task Scheduler—has yesterday released another proof-of-concept exploit for a new Windows zero-day vulnerability. SandboxEscaper posted a link to a Github page hosting a proof-of-concept (PoC) exploit for the vulnerability that appears to be a privilege escalation flaw residing in Microsoft Data Sharing (dssvc.dll). The Data Sharing Service is a local service that runs as LocalSystem account with extensive privileges and provides data brokering between applications. The flaw could allow a low-privileged attacker to elevate their privileges on a target system, though the PoC exploit code (deletebug.exe) released by the researcher only allows a low privileged user to delete critical system files—that otherwise would only be possible via admin level privileges. "Not the same bug I posted a while back, this doesn't write garbage to files

Two Zero-Day Exploits Found After Someone Uploaded 'Unarmed' PoC to VirusTotal

July 02, 2018Swati Khandelwal
Security researchers at Microsoft have unveiled details of two critical and important zero-day vulnerabilities that had recently been discovered after someone uploaded a malicious PDF file to VirusTotal, and get patched before being used in the wild . In late March, researchers at ESET found a malicious PDF file on VirusTotal, which they shared with the security team at Microsoft "as a potential exploit for an unknown Windows kernel vulnerability." After analyzing the malicious PDF file, the Microsoft team found that the same file includes two different zero-day exploits—one for Adobe Acrobat and Reader, and the other targeting Microsoft Windows. Since the patches for both the vulnerabilities were released in the second week of May, Microsoft released details of both the vulnerabilities today, after giving users enough time to update their vulnerable operating systems and Adobe software. According to the researchers, the malicious PDF including both the zero-days e
Google Researcher Releases iOS Exploit—Could Enable iOS 11 Jailbreak

Google Researcher Releases iOS Exploit—Could Enable iOS 11 Jailbreak

December 11, 2017Swati Khandelwal
As promised last week , Google's Project Zero researcher Ian Beer now publicly disclosed an exploit that works on almost all 64-bit Apple devices running iOS 11.1.2 or earlier, which can be used to build an iOS jailbreak, allowing users to run apps from non-Apple sources. On Monday morning, Beer shared the details on the exploit, dubbed "tfp0," which leveraged double-free memory corruption vulnerabilities in the kernel, the core of the operating system. Here, " tfp0 " stands for " task for pid 0 " or the kernel task port—which gives users full control over the core of the operating system. The Project Zero researcher responsibly reported these vulnerabilities to Apple in October, which were patched by the company with the release of iOS 11.2 on 2nd December. While Beer says he has successfully tested his proof of concept exploit on the iPhone 6s and 7, and iPod Touch 6G, he believes that his exploit should work on all 64-bit Apple devices.

Hackers Use New Flash Zero-Day Exploit to Distribute FinFisher Spyware

October 16, 2017Mohit Kumar
FinSpy —the infamous surveillance malware is back and infecting high-profile targets using a new Adobe Flash zero-day exploit delivered through Microsoft Office documents. Security researchers from Kaspersky Labs have discovered a new zero-day remote code execution vulnerability in Adobe Flash, which was being actively exploited in the wild by a group of advanced persistent threat actors, known as BlackOasis . The critical type confusion vulnerability, tracked as CVE-2017-11292 , could lead to code execution and affects Flash Player 21.0.0.226 for major operating systems including Windows, Macintosh, Linux and Chrome OS. Researchers say BlackOasis is the same group of attackers which were also responsible for exploiting another zero-day vulnerability ( CVE-2017-8759 ) discovered by FireEye researchers in September 2017. Also, the final FinSpy payload in the current attacks exploiting Flash zero-day (CVE-2017-11292) shares the same command and control (C&C) server as the
First Android Malware Found Exploiting Dirty COW Linux Flaw to Gain Root Privileges

First Android Malware Found Exploiting Dirty COW Linux Flaw to Gain Root Privileges

September 26, 2017Swati Khandelwal
Nearly a year after the disclosure of the Dirty COW vulnerability that affected the Linux kernel, cybercriminals have started exploiting the vulnerability against Android users, researchers have warned. Publicly disclosed last year in October, Dirty COW was present in a section of the Linux kernel—a part of virtually every Linux distribution, including Red Hat, Debian, and Ubuntu—for years and was actively exploited in the wild. The vulnerability allows an unprivileged local attacker to gain root access through a race condition issue, gain access to read-only root-owned executable files, and permit remote attacks. However, security researchers from Trend Micro published a blog post on Monday disclosing that the privilege escalation vulnerability (CVE-2016-5195), known as Dirty COW, has now been actively exploited by a malware sample of ZNIU, detected as AndroidOS_ZNIU. This is the first time we have seen a malware sample to contain an exploit for the vulnerability designed
