Apple Mac OS X Vulnerability Allows Attackers to Hack your Computer

Apple Mac OS X Vulnerability Allows Attackers to Hack your Computer

Jul 23, 2015
A security researcher has discovered a critical vulnerability in the latest version of Apple's OS X Yosemite  that could allow anyone to obtain unrestricted root user privileges with the help of code that fits in a tweet. The privilege-escalation vulnerability initially reported on Tuesday by German researcher Stefan Esser , could be exploited by to circumvent security protections and gain full control of Mac computers. The most worrying part is that this critical vulnerability is yet to be fixed by Apple in the latest release of its operating system. This could make it easier for hackers to surreptitiously infect Macs with rootkits and other types of persistent malware. Thanks to an environment variable DYLD_PRINT_TO_FILE Apple added to the code of OS X 10.10 Yosemite. Apple Mac OS X Vulnerability Gives Full Control of your Mac This environment variable specifies where in the file system an operating system component called the OS X dynamic linker dyld
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
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.
