Apple Macs At Risk From ‘Rising’ Malware Attacks

Apple not so safe after all. Rapid rise in malware targeting Mac devices, as Android security problem worsens
Malwarebytes has warned Apple Mac users that the days of their devices being relatively safe from malware are long over.
The security specialist analysed data from millions of its users worldwide and it discovered that Mac and Android ransomware and malware attacks have risen significantly in the past year.
Indeed, Malwarebytes found that more Mac malware had been detected in Q2 2017 than in all of 2016.

Mac Malware

According to the security vendor, the “rapidly rising rates of malware” targetting Mac devices should disperse the popular belief that Macs are impenetrable.
Fruitfly creates a backdoor that allows attackers to take screen captures and remotely control the Mac system.
“More malware families have emerged in 2017 than in any other previous year – and we’re only in August,” warned Malwarebytes. In fact, more new malware families have appeared this year than in any other previous year in Mac history.
To this end,  Malwarebytes has introduced ‘Malwarebytes for Mac‘, which offers real-time protection for Mac users to automatically block and remove cyber threats, including malware, adware and potentially unwanted programs.
“We carefully designed Malwarebytes for Mac to protect all Mac users from cyber threats and potentially unwanted programs so that they can feel safe and have a Mac that performs like it should,” explained Marcin Kleczynski, CEO, Malwarebytes.
“Antivirus and security awareness is no longer enough defence for Mac users, the growth of Mac malware has made that very clear. We hope that more and more Mac users will come to this realisation  and begin to seek out additional defences.”
Malwarebytes for Mac includes a real-time anti-malware protection scanner that allows for “ultra-fast proactive scanning for malware and spyware in real-time, in addition to flagging potentially unwanted programs and adware.”
And Malwarebytes for Mac can either completely replace an existing antivirus solutions or can run alongside any antivirus program. It also boasts a small system footprint that utilises minimal system resources to ensure that Macs run smoothly.
Mac threats are not taken seriously enough in the security community today,” added Thomas Reed, Director of Mac and Mobile, Malwarebytes. “Adware and potentially unwanted programs are becoming a major problem for Mac users. Some very popular apps have been known to carry these threats and despite protections in place, the App Store is not immune to these threats.
“For example, the recent Proton Remote Access Trojan that plagued Mac users fooled many experienced, security-minded people who became infected. This perpetuates a crucial lesson that, despite what many Mac users think, they are not safe even if they are careful about what they download.
“Being security-savvy is no longer enough, all Mac users need dedicated protection against malware, adware and potentially unwanted programs.”

Android Security

There was equally grim news for those in the Android community, as ransomware here increased more than 100 percent between Q1 and Q2 2017. Indeed, Malwarebytes data showed that incidences of Android malware increased more than five percent since the start of the year.
And to make matters worse, incidents of Android ransomware increased 138 percent in Q2 2017 (April to May) over Q1 (January to March) 2017. Malwarebytes found that JisutSLocker and Koler ransomware collectively accounted for nearly 95 percent of these detections.
And although Android ransomware is growing at this rapid pace, Trojans and potentially unwanted programs still remain the biggest headaches for Android users.
Android Trojans accounted for more than 48 percent of all Android malware detections in the first half of 2017 and potentially unwanted programs accounted for 47 percent of all detections.

Quimitch: The first Mac malware of 2017

The first Mac malware of 2017 has been detected and brings to question whether Macs still safe from bad guys or whether malware lurks there undetected.


Mac users usually feel safe when it comes to malicious software attacking their systems. Viruses, worms and other kinds of malware are relatively rare comparing with Microsoft Windows users. However, in the last couple of years, the situation has been changing and it seems that the attention of malware creators is turning towards Mac users.

Key Points
  • The malicious code is extremely simple and consists only of two files.
  • The code of malware seems truly ancient with calls dating to pre-OS X times and open source libraries, with the latest update being from the last century.
  • Malware targets specific institutions – biomedical research centers. This points to the fact that it could be an attempt to steal research data or other kinds of espionage.
  • Malware needs access to the webcam and to capture the screen, exfiltrating data from everything it can access.


Overview
There are few interesting things about Quimitchin, the name comes from the Aztec spies that infiltrated other tribes (That’s because the code of the malware itself is ancient or at least it seems so!) – first and foremost, it might have been running on specific systems undetected for years. Why was it undetected? Targeted attacks are much more difficult to detect because of their limited exposure and this is the case with Quimitchin, which is most likely espionage tool. The malware tries to access the webcam with primitive calls, dating back to pre-OS X times. It also tries to screen capture, has rudiments of a remote control function, with possibility to receive commands like change the position of mouse cursor or simulate mouse clicks.
It consists of two files – one for keeping the client alive and another Perl script – for communication with command and control servers, taking screenshots, accessing the webcam and other activities. It can also scan your network, build a map of all devices, try and connect to them or report IP addresses and other information.
What’s even more interesting, the malware code has Linux shell commands too. This might point that there is similar malware existing in Linux systems. Up to this date, the existence of such cannot be confirmed. However, communications with the same command and control center were reported a couple of times to Virus Total before. 
No one knows how this piece of malware is installed, who created it and for how long it was stealing scientific research data and this mysterious twist is one of the reasons why Quimitchin is one of the most interesting pieces of malware early in 2017. Although who the creators are isn't clear, as researchers dig into it, time will reveal who was standing behind the curtain.


Relevance to your security
This malware can infect your Mac computer. Although, unless you are working at a biomedical research institution, you shouldn’t worry too much. On the other hand, the discovery of this malware, using such ancient techniques, might show that there can be a lot of bad things happening undetected with your OS X and Mac computer.
Webcam access: Possibility to capture images, record video. Though further investigation of code is needed.
Capture screen: Capture what is happening on your screen and transferring images. 
Remote control: It can remotely control your computer – simulate key presses, mouse clicks, cursor position and gather your network data – IP addresses, network names and port that it uses.


Conclusion
Quimitchin is one of the mysteries of early 2017 that surfaced in cyber security field. There are more things unknown than known regarding activities of this malware, creators, purpose and for how long it was being used undetected.
