New Mac Malware Targets Cookies to Steal From Cryptocurrency Wallets
February 01, 2019Mohit Kumar
Mac users need to beware of a newly discovered piece of malware that steals their web browser cookies and credentials in an attempt to withdraw funds from their cryptocurrency exchange accounts. Dubbed CookieMiner due to its capability of stealing cookies-related to cryptocurrency exchanges, the malware has specifically been designed to target Mac users and is believed to be based on DarthMiner, another Mac malware that was detected in December last year. Uncovered by Palo Alto Networks' Unit 42 security research team, CookieMiner also covertly installs coin mining software onto the infected Mac machines to secretly mine for additional cryptocurrency by consuming the targeted Mac's system resources. In the case of CookieMiner, the software is apparently geared toward mining "Koto," a lesser-known, privacy-oriented cryptocurrency which is mostly used in Japan. However, the most interesting capabilities of the new Mac malware is to steal: Both Google Chro

Yes, even Mac could also get viruses that could silently spy on its users. So, if you own a Mac and think you are immune to malware, you are wrong. An unusual piece of malware that can remotely take control of webcams, screen, mouse, keyboards, and install additional malicious software has been infecting hundreds of Mac computers for more than five years—and it was detected just a few months back. Dubbed FruitFly , the Mac malware was initially detected earlier this year by Malwarebytes researcher Thomas Reed, and Apple quickly released security patches to address the dangerous malware. Now months later, Patrick Wardle, an ex-NSA hacker and now chief security researcher at security firm Synack, discovered around 400 Mac computers infected with the newer strain of the FruitFly malware (FruitFly 2) in the wild. Wardle believes the number of infected Macs with FruitFly 2 would likely be much higher, as he only had access to some servers used to control FruitFly. Although it i

Many people believe that they are much less likely to be bothered by malware if they use a Mac computer, but is it really true? Unfortunately, No. According to the McAfee Labs , malware attacks on Apple's Mac computers were up 744% in 2016, and its researchers have discovered nearly 460,000 Mac malware samples, which is still just a small part of overall Mac malware out in the wild. Today, Malware Research team at CheckPoint have discovered a new piece of fully-undetectable Mac malware, which according to them, affects all versions of Mac OS X, has zero detections on VirusTotal and is "signed with a valid developer certificate (authenticated by Apple)." Dubbed DOK , the malware is being distributed via a coordinated email phishing campaign and, according to the researchers, is the first major scale malware to target macOS users. The malware has been designed to gain administrative privileges and install a new root certificate on the target system, which allows

Watch Out! First-Ever Word Macro Malware for Apple Mac OS Discovered in the Wild
February 09, 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

Security researchers have discovered a rare piece of Mac-based espionage malware that relies on outdated coding practices but has been used in some previous real-world attacks to spy on biomedical research center computers. Dubbed Fruitfly , the malware has remained undetected for years on macOS systems despite using unsophisticated and "antiquated code." Infosec firm Malwarebytes discovered Fruitfly, detected as 'OSX.Backdoor.Quimitchin,' after one of its IT administrators spotted some unusual outgoing activity from a particular Mac computer. According to the researchers, the recently discovered what they're calling "the first Mac malware of 2017" contains code that dates before OS X, which has reportedly been conducting detailed surveillance operation on targeted networks, possibly for over two years. Fruitfly uses a hidden pearl script to communicate back to two command-and-control (C&C) servers and has the ability to perform actions l

Mac users, even you are not left untouched! The World's first fully functional Ransomware targeting OS X operating system has been landed on Macs. Ransomware – one of the fastest-growing cyber threats – encrypts the important documents and files on infected machines and then asks victims to pay ransoms in digital currencies so they can regain access to their data. Though Ransomware has been targeting smartphones and Windows computers for a while, Mac OS X users haven't really had to worry about this threat… until now! As security researchers from Palo Alto Networks claims to have discovered the very first known instance of OS X Ransomware in the wild, called " KeRanger " attacking Apple's Macintosh computers, firm's Threat Intelligence Director Ryan Olson told Reuters. The KeRanger ransomware, which appeared on Friday, comes bundled into the popular Mac app Transmission , a free and open-source BitTorrent client for Mac with Millio

Earlier this week, new Mac spyware was discovered on a computer at the Oslo Freedom Forum , which is an annual human rights conference. Dubbed as  OSX/KitM.A , discovered by computer security researcher Jacob Appelbaum . This Mac malware that has been used to spy on activists, targeted via spear phishing attack and had received emails that duped them into installing the malware. The malware is a backdoor application called " macs.app " which launches automatically upon login. There are two command-and-control servers, located at securitytable.org and docsforum.info. Interestingly, the malware is signed with an Apple Developer ID , which is designed to prevent the installation of malware, associated with the name Rajender Kumar  and  the use of the ID appears to be an attempt to bypass Apple's Gatekeeper execution prevention technology. As of right now, F-Secure is looking into the origination of the malware and though it doesn't appear to be widespread.  You can

New Mac malware opens secure connection for a remote hacker
February 20, 2013Mohit Kumar
A new malware threat for the Mac has been discovered that attempting to set up a secure connection for a remote hacker to connect through and grab private information. Dubbed " Pintsized " that uses a modified version of OpenSSH to potentially set up a remote connection into Mac accounts. This backdoor Trojan can be used to conduct distributed denial of service (DDoS) attacks, or it can be used to install additional Trojans or other forms of malicious software. Since the connection between the hacker and the machine is encrypted, it becomes very hard for the Trojan to be detected or traced. The threat has the potential to become serious, as it uses an exploit in OS X to bypass Gatekeeper and establish a reverse shell that creates a secure connection.  Trojan stays hidden by disguising itself as a file that is used for networked printers in Mac OS X. The location of the malware has been traced to this particular directory. This tactic conceals the Trojan and makes a moni

A new trojan horse app called Dockster is targeting Mac users by exploiting a known Java vulnerability CVE-2012-0507. The trojan is apparently being delivered through a website (gyalwarinpoche.com) dedicated to the Dalai Lama and once installed can collect user keystrokes and other personal information. Mac in Danger ?  Earlier this spring, a Russian security firm discovered a trojan piece of malware which took advantage of a Java vulnerability on many computers, Macs and PCs alike. This trojan, known as "Flashback," was used to enlist some 600,000 infected computers into a botnet. Malware also provides an interface that allows attackers to download and execute additional malware. Dockster has been found to use the same exploit code as the previous SabPab virus to gain access through a backdoor. Dockster is also said to launch an agent called mac.dockset.deman, which restarts each time a user logs in to their Mac. Dockster is only the latest Mac-based threat to h
