New Mac Malware Exploits GateKeeper Bypass Bug that Apple Left Unpatched

June 25, 2019Mohit Kumar
Cybersecurity researchers from Intego are warning about possible active exploitation of an unpatched security vulnerability in Apple's macOS Gatekeeper security feature details and PoC for which were publicly disclosed late last month. Intego team last week discovered four samples of new macOS malware on VirusTotal that leverage the GateKeeper bypass vulnerability to execute untrusted code on macOS without displaying users any warning or asking for their explicit permission. However, the newly discovered malware, dubbed OSX/Linker , has not been seen in the wild as of now and appears to be under development. Though the samples leverage unpatched Gatekeeper bypass flaw, it does not download any malicious app from the attacker's server. According to Joshua Long from Intego, until last week, the "malware maker was merely conducting some detection testing reconnaissance." "One of the files was signed with an Apple Developer ID (as explained below), it is

June 21, 2019Mohit Kumar
Cybersecurity researchers from at least two firms today unveiled details of a new strain of malware that targets Windows and macOS systems with a Linux-based cryptocurrency mining malware. It may sound strange, but it's true. Dubbed " LoudMiner " and also " Bird Miner, " the attack leverages command-line based virtualization software on targeted systems to silently boot an image of Tiny Core Linux OS that already contains a hacker-activated cryptocurrency mining software in it. Isn't it interesting to use emulation to run single-platform malware on cross-platforms? Spotted by researchers at ESET and Malwarebytes , attackers are distributing this malware bundled with pirated and cracked copies of VST (Virtual Studio Technology) software on the Internet and via Torrent network since August 2018. VST applications contain sounds, effects, synthesizers, and other advanced editing features that allow tech-centric audio professionals to create music.

June 21, 2019Mohit Kumar
Okay, folks, it's time to update your Firefox web browser once again—yes, for the second time this week. After patching a critical actively-exploited vulnerability in Firefox 67.0.3 earlier this week, Mozilla is now warning millions of its users about a second zero-day vulnerability that attackers have been found exploiting in the wild. The newly patched issue ( CVE-2019-11708 ) is a "sandbox escape" vulnerability, which if chained together with the previously patched "type confusion" bug ( CVE-2019-11707 ), allows a remote attacker to execute arbitrary code on victims' computers just by convincing them into visiting a malicious website. Browser sandboxing is a security mechanism that keeps third-party processes isolated and confined to the browser, preventing them from damaging other sensitive parts of a computer's operating system.

Popular Video Editing Software Website Hacked to Spread Banking Trojan

April 11, 2019Swati Khandelwal
If you have downloaded the VSDC multimedia editing software between late February to late March this year, there are high chances that your computer has been infected with a banking trojan and an information stealer. The official website of the VSDC software — one of the most popular, free video editing and converting app with over 1.3 million monthly visitors — was hacked, unfortunately once again. According to a new report Dr. Web published today and shared with The Hacker News, hackers hijacked the VSDC website and replaced its software download links leading to malware versions, tricking visitors into installing dangerous Win32.Bolik.2 banking trojan and KPOT stealer. Even more ironic is that despite being so popular among the multimedia editors, the VSDC website is running and offering software downloads over an insecure HTTP connection. Though it's unclear how hackers this time managed to hijack the website, researchers revealed that the breach was reportedly ne

Sophisticated 'TajMahal APT Framework' Remained Undetected for 5 Years

April 10, 2019Swati Khandelwal
Cybersecurity researchers yesterday unveiled the existence of a highly sophisticated spyware framework that has been in operation for at least last 5 years—but remained undetected until recently. Dubbed TajMahal by researchers at Kaspersky Lab, the APT framework is a high-tech modular-based malware toolkit that not only supports a vast number of malicious plugins for distinct espionage operations, but also comprises never-before-seen and obscure tricks. Kaspersky named the framework after Taj Mahal, one of the Seven Wonders of the World located in India, not because it found any connection between the malware and the country, but because the stolen data was transferred to the attackers' C&C server in an XML file named TajMahal. TajMahal toolkit was first discovered by security researchers late last year when hackers used it to spy on the computers of a diplomatic organization belonging to a Central Asian country whose nationality and location have not been disclosed

'Exodus' Surveillance Malware Found Targeting Apple iOS Users

April 09, 2019Swati Khandelwal
Cybersecurity researchers have discovered an iOS version of the powerful mobile phone surveillance app that was initially targeting Android devices through apps on the official Google Play Store. Dubbed Exodus , as the malware is called, the iOS version of the spyware was discovered by security researchers at LookOut during their analysis of its Android samples they had found last year. Unlike its Android variant, the iOS version of Exodus has been distributed outside of the official App Store, primarily through phishing websites that imitate Italian and Turkmenistani mobile carriers. Since Apple restricts direct installation of apps outside of its official app store, the iOS version of Exodus is abusing the Apple Developer Enterprise program, which allows enterprises to distribute their own in-house apps directly to their employees without needing to use the iOS App Store. "Each of the phishing sites contained links to a distribution manifest, which contained metadata

Patched WinRAR Bug Still Under Active Attack—Thanks to No Auto-Updates

March 15, 2019Swati Khandelwal
Various cyber criminal groups and individual hackers are still exploiting a recently patched critical code execution  vulnerability in WinRAR , a popular Windows file compression application with 500 million users worldwide. Why? Because the WinRAR software doesn't have an auto-update feature, which, unfortunately, leaves millions of its users vulnerable to cyber attacks. The critical vulnerability (CVE-2018-20250) that was patched late last month by the WinRAR team with the release of WinRAR version 5.70 beta 1 impacts all prior versions of WinRAR released over the past 19 years. For those unaware, the vulnerability is "Absolute Path Traversal" bug that resides in the old third-party library UNACEV2.DLL of WinRAR and allows attackers to extract a compressed executable file from the ACE archive to one of the Windows Startup folders, where the malicious file would automatically run on the next reboot. Therefore, to successfully exploit this vulnerability and tak

Google Discloses Unpatched 'High-Severity' Flaw in Apple macOS Kernel

March 04, 2019Mohit Kumar
Cybersecurity researcher at Google's Project Zero division has publicly disclosed details and proof-of-concept exploit of a high-severity security vulnerability in macOS operating system after Apple failed to release a patch within 90 days of being notified. Discovered by Project Zero researcher Jann Horn and demonstrated by Ian Beer, the vulnerability resides in the way macOS XNU kernel allows an attacker to manipulate filesystem images without informing the operating system. The flaw could eventually allow an attacker or a malicious program to bypass the copy-on-write (COW) functionality to cause unexpected changes in the memory shared between processes, leading to memory corruption attacks. Copy-On-Write, also referred to as COW, is a resource-management optimization strategy used in computer programming. In general, if any process (destination) requires a file or data that is already in the memory but created by another process (source), both processes can share the
Researchers Implant "Protected" Malware On Intel SGX Enclaves

Researchers Implant "Protected" Malware On Intel SGX Enclaves

February 13, 2019Swati Khandelwal
Cybersecurity researchers have discovered a way to hide malicious code in Intel SGX enclaves, a hardware-based memory encryption feature in modern processors that isolates sensitive code and data to protect it from disclosure or modification. In other words, the technique allows attackers to implant malware code in a secure memory that uses protection features of SGX which are otherwise designed to protect important data from prying eyes or from being tampered, even on a compromised system. Introduced with Intel's Skylake processors, SGX (Software Guard Extensions) allows developers to run selected application modules in a completely isolated secure region of memory, called enclaves, which are designed to be protected from processes running at higher privilege levels like the operating system, kernel, BIOS, SMM, hypervisor, etc. However, a team of researchers, some of whom were behind the discovery of the Spectre-Meltdown CPU flaws , managed to bypass this protection and g
