Watch Out! First-Ever Word Macro Malware for Apple Mac OS Discovered in the Wild

Watch Out! First-Ever Word Macro Malware for Apple Mac OS Discovered in the Wild
February 10, 2017Swati Khandelwal
After targeting Windows-based computers over the past few years, hackers are now shifting their interest to Macs as well. The emergence of the first macro-based Word document attack against Apple's macOS platform is the latest example to prove this. The concept of Macros dates back to 1990s. You might be familiar with the message that reads: " Warning: This document contains macros. " Macro is a series of commands and actions that help automate some tasks. Microsoft Office programs support Macros written in Visual Basic for Applications (VBA), but they can also be used for malicious activities like installing malware. Until now, hackers were cleverly using this technique to target Windows. However, security researchers have now detected the first in-the-wild instance of hackers are making use of malicious macros in Word documents to install malware on Mac computers and steal your data – an old Windows technique. The hack tricks victims into opening infected W

Mac OS X Zero-Day Exploit Can Bypass Apple's Latest Protection Feature

Mac OS X Zero-Day Exploit Can Bypass Apple's Latest Protection Feature
March 25, 2016Swati Khandelwal
A critical zero-day vulnerability has been discovered in all versions of Apple's OS X operating system that allows hackers to exploit the company's newest protection feature and steal sensitive data from affected devices. With the release of OS X El Capitan, Apple introduced a security protection feature to the OS X kernel called System Integrity Protection ( SIP ). The feature is designed to prevent potentially malicious or bad software from modifying protected files and folders on your Mac. The purpose of SIP is to restrict the root account of OS X devices and limit the actions a root user can perform on protected parts of the system in an effort to reduce the chance of malicious code hijacking a device or performing privilege escalation. However, SentinelOne security researcher Pedro Vilaça has uncovered a critical vulnerability in both OS X and iOS that allows for local privilege escalation as well as bypasses SIP without kernel exploit, impacting all versions

A pair of new security vulnerabilities has been discovered in the framework used by a wide variety of Mac apps leaves them open to Man-in-the-Middle (MitM) attacks. The framework in question is Sparkle that a large number of third-party OS X apps, including Camtasia, uTorrent, Duet Display and Sketch, use to facilitate automatic updates in the background. Sparkle is an open source software available on GitHub under the permissive MIT license by the Sparkle Project with the help of numerous of valuable contributors. The framework supports Mac OS X versions 10.7 through 10.11 and Xcode 5.0 through 7.0. The Sparkle vulnerabilities, discovered by Radek, a security researcher, in late January and reported by Ars reporter, affect Apple Mac apps that use: An outdated and vulnerable version of the Sparkle updater framework. An unencrypted HTTP channel to receive info from update servers. What's the Issue? The first loophole is due to the improper implemen

Apple's Mac OS X Still Open to Malware, Thanks Gatekeeper

Apple's Mac OS X Still Open to Malware, Thanks Gatekeeper
January 16, 2016Swati Khandelwal
Apple Mac Computers are considered to be much safer than Windows computers at keeping out the viruses and malware, but the new Exploit discovered by researchers again proves it indeed quite false. Last year, The Hacker News reported a deadly simple exploit that completely bypassed one of the core security features in Mac OS X known as Gatekeeper . Apple released a patch in November, but now the same security researcher who discovered the original Gatekeeper bypass vulnerability said he found an equally obvious workaround. Patrick Wardle, ex-NSA staffer and head of research at security intelligence firm Synack, said the security patch released by Apple was " incredibly weak " and that the update was " easy to bypass " in minutes. Gatekeeper's Failure Once Again Introduced in July of 2012, Gatekeeper is Apple's anti-malware feature designed to block untrusted, dodgy apps from running, keeping Mac OS X systems safe from malware.

Zero-Day Exploits for Stealing OS X and iOS Passwords

Zero-Day Exploits for Stealing OS X and iOS Passwords
June 19, 2015Swati Khandelwal
I think you'll agree with me when I say: Apple devices are often considered to be more safe and secure than other devices that run on platforms like Windows and Android, but a recent study will make you think twice before making this statement. A group of security researchers have uncovered potentially deadly zero-day vulnerabilities in both iOS and OS X operating systems that could put iPhone/iPad or Mac owners at a high risk of cyber attacks. Researchers have created and published a malicious app on the App Store that was able to siphon users' personal data from the password storing Keychain in Apple's OS X , as well as steal passwords from iCloud, banking and email accounts. Dubbed XARA (cross-app resource access), the malware exploit app was able to bypass the OS X sandboxing mechanisms that are supposedly designed to prevent an app from accessing the credentials, contacts, and other important data related to other apps. The Consequences are Dire!

The Flashback Trojan, the most sophisticated piece of malware that infected over 600,000 Apple's Macs systems back in April, 2012 is still alive and has infected about 22,000 machines recently, according to the researchers from Intego . For a refresh, Flashback Trojan was first discovered in September 2011, basically a trojan horse that uses a social engineering to trick users into installing a malicious Flash player package. Once installed, the Flashback malware injects a code into that web browser and other applications like Skype to harvest passwords and other information from those program's users. The Trojan targets a known vulnerability in Java on Mac OS X systems. The system gets infected after the user redirects to a compromised website, where a malicious javascript code to load the exploit with Java applets. Then an executable file is saved on the local machine, which is used to download and run malicious code from a remote location. It took Apple months to recogni

Apple's own Encryption Mechanism allows hacker to create an Undetectable Mac OS X Malware

Apple's own Encryption Mechanism allows hacker to create an Undetectable Mac OS X Malware
October 08, 2013Mohit Kumar
In the past, there was a general belief that Macs is much more secure than Windows PCs, but now Mac malware is a serious threat to the security of users' computers and information. One of the reasons behind the increase in Mac related Malware attacks is the fact that Apple products are popular with many prominent businessmen and influential politicians. Daniel Pistelli, Reverse Engineer and lead developer of Cerbero Profiler, former developer of IDA Pro comes up with another interesting research, and explained The Hacker News , the basic details behind the technique he used to create an undetectable malware for Mac OS X. Apple implements internally an encryption mechanism to protect some of their own executable like " Dock.app " or " Finder.app ". This encryption can be applied to malware as well. If one does, anti-malware solutions can no longer detect the malware because of the encryption, but OS X has no problem loading such malware. This same

Apple Mac OS X Vulnerability enables Root User to Hackers by resetting the clock

Apple Mac OS X Vulnerability enables Root User to Hackers by resetting the clock
August 31, 2013Mohit Kumar
Do you think, because you're using an Apple Mac , your data is safe from hackers ? Well, it is not true, there are dozens of security weaknesses and today Researchers have made it easier to exploit Apple Mac OS X, that allows penetration testers and hackers to gain root access. The flaw remained unmatched by Apple for the last five months, dubbed CVE-2013-1775 , the flaw allowed attackers to bypass normal password authentication procedures by resetting the computer clock to January 1, 1970. The reason that specific date is required is because it represents the beginning of time to the operating system and some applications that run on it. When the SUDO command is used in combination with a clock reset, the computer can be tracked into providing root access without a password. Metasploit authors have come up with a brand new module that makes the bug even easier to exploit , renewing interest in the problem. The module gains a session with root permissions as long as the use
