macOS Under Attack: Examining the Growing Threat and User Perspectives

macOS Under Attack: Examining the Growing Threat and User Perspectives
Jul 25, 2023 Endpoint Security / macOS
As the number of people using macOS keeps going up, so does the desire of hackers to take advantage of flaws in Apple's operating system.  What Are the Rising Threats to macOS? There is a common misconception among macOS fans that Apple devices are immune to hacking and malware infection. However, users have been facing more and more dangers recently. Inventive attackers are specifically targeting Mac systems, as seen with the "Geacon" Cobalt Strike tool attack. This tool enables them to perform malicious actions such as data theft, privilege elevation, and remote device control, placing the security and privacy of Mac users at grave risk. Earlier this year, researchers also uncovered the MacStealer malware, which also stole sensitive data from Apple users. Documents, iCloud keychain data, browser cookies, credit card credentials – nothing is safe from the prying eyes.  But that's not all. CloudMensis is malicious software that specifically targets macOS systems,

Flaw in Zoom Video Conferencing Software Lets Websites Hijack Mac Webcams

Flaw in Zoom Video Conferencing Software Lets Websites Hijack Mac Webcams
Jul 09, 2019
If you use Zoom video conferencing software on your Mac computer—then beware—any website you're visiting in your web browser can turn on your device camera without your permission. Ironically, even if you had ever installed the Zoom client on your device and simply uninstalled it, a remote attacker can still activate your webcam. Zoom is one of the most popular cloud-based meeting platforms that provide video, audio, and screen sharing options to users, allowing them to host webinars, teach online courses, conduct online training, or join virtual meetings online. In a Medium post published today, cybersecurity researcher Jonathan Leitschuh disclosed details of an unpatched critical security vulnerability (CVE-2019-13450) in the Zoom client app for Apple Mac computers, which if combined with a separate flaw, could allow attackers to execute arbitrary code on the targeted systems remotely. Jonathan responsibly reported the security vulnerability to the affected company ov

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Making Sense of Operational Technology Attacks: The Past, Present, and Future
Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.

If you have recently downloaded the popular open source video transcoder app HandBrake on your Mac, there are chances that your computer is infected with a notorious Remote Access Trojan (RAT). The HandBrake team issued a security alert on Saturday, warning Mac users that one of its mirror servers to download the software has been compromised by hackers. In case you aren't aware, HandBrake is an open source video transcoder app that allows Mac users to convert multimedia files from one format to another. According to the HandBrake team, an unknown hacker or group of hackers compromised the download mirror server (download.handbrake.fr) and then replaced the Mac version of the HandBrake client (HandBrake-1.0.7.dmg) with a malicious version infected with a new variant of Proton . Originally discovered in February on a Russian underground hacking forum, Proton is a Mac-based remote access trojan that gives attackers root access privileges to the infected system. The af

Critical Flaw in ESET Antivirus Exposes Mac Users to Remote Hacking

Critical Flaw in ESET Antivirus Exposes Mac Users to Remote Hacking
Feb 28, 2017
What could be more exciting for hackers than exploiting a vulnerability in a widely used software without having to struggle too much? One such easy-to-exploit, but critical vulnerability has been discovered in ESET's antivirus software that could allow any unauthenticated attackers to remotely execute arbitrary code with root privileges on a Mac system. The critical security flaw, tracked as CVE-2016-9892, in ESET Endpoint Antivirus 6 for macOS was discovered by Google Security Team's researchers Jason Geffner and Jan Bee at the beginning of November 2016. As detailed in the full disclosure , all a hacker needs to get root-level remote code execution on a Mac computer is to intercept the ESET antivirus package's connection to its backend servers using a self-signed HTTPS certificate, put himself in as a man-in-the-middle (MITM) attacker, and exploit an XML library flaw. The actual issue was related to a service named esets_daemon, which runs as root. The service

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

Apple's Mac OS X Still Open to Malware, Thanks Gatekeeper
Jan 16, 2016
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.

13 Million MacKeeper Users Hacked — 21 GB of Data Exposed
Dec 15, 2015
MacKeeper anti-virus company is making headlines today for its lax security that exposed the database of 13 Million Mac users' records including names, email addresses, usernames, password hashes, IP addresses, phone numbers, and system information. MacKeeper is a suite of software that claims to make Apple Macs more secure and stable, but today the anti-virus itself need some extra protection after a data breach exposed the personal and sensitive information for Millions of its customers. The data breach was discovered by Chris Vickery , a white hat hacker who was able to download 13 Million customer records by simply entering a selection of IP addresses, with no username or password required to access the data. 21 GB Trove of MacKeeper Customer Data Leaked 31-year-old Vickery said he uncovered the 21 GB trove of MacKeeper customer data in a moment of boredom while searching for openly accessible databases on Shodan – a specialized search engine that looks fo

First Time Ever Apple Automatically Pushes Security Patch for Mac OS

First Time Ever Apple Automatically Pushes Security Patch for Mac OS
Dec 24, 2014
First time ever in the History, Apple Inc. has pushed out an automatic security update for Macintosh OS X computers to address a critical security issue that, according to the company, was too risky to wait for users to patch after seeking their prior approval. Despite having the ability for years to silently and automatically update its users computers, Apple typically asks its users' permission to approve them manually or automatically before installing any security update of this kind. But, the company has exercised its ability for the very first time to patch a critical security flaw in a component of its OS X operating system called the Network Time Protocol (NTP) . This newly discovered security vulnerability, assigned CVE-2014-9295, became public late last week and affects all operating systems, including OS X and other Linux and Unix distributions, running versions of NTP4 prior to 4.2.8. NTP is used for synchronizing clocks between computer systems and across the globa

Over 17000 Mac Machines Affected by 'iWorm' Botnet Malware

Over 17000 Mac Machines Affected by 'iWorm' Botnet Malware
Oct 06, 2014
A newly discovered zombie network that exclusively targets Apple computers running Mac OS X across the globe has compromised roughly 17,000 machines so far, giving hackers backdoor access to infected computers, researchers at Russian antivirus firm Dr.Web warned. According to a survey of traffic conducted in September by researchers at Dr. Web, over 17,000 Macs globally are part of the Mac.BackDoor.iWorm botnet , which creates a backdoor on machines running OS X. Researchers say almost a quarter of iWorm botnet are located in the US. The most interesting thing to notice about this botnet is that it uses a special method of spreading via a search service of Reddit posts to a Minecraft server list subreddit to collect the IP addresses for its command and control (CnC) network. The user who had posted that subreddit data has now been shut down though the malware creators are likely to form another server list. " It is worth mentioning that in order to acquire a control server add
