#MALWARE YEARS USED RUNONLY APPLESCRIPTS TO UPDATE#

Software with x86_64 architecture can still run on macOS 11 with the help of Rosetta 2, an emulator built into Big Sur, but most software developers may prefer to update their software so it can support ARM64.Īccording to Kaspersky, new samples from the malware were discovered that can run on Macs with the new M1 chip.

Last November, Apple released its operating system Big Sur alongside new Mac products equipped with ARM-based M1 processors. Our follow-up update covered the third exploit we found that takes advantage of other popular browsers in macOS to implant a Universal Cross-site Scripting (UXSS) injection. In our first blog post and technical brief on XCSSET, we discussed at length the dangers it posed to Xcode developers and how it exploited two macOS vulnerabilities to maximize what it can take from an infected machine. This latest update details our new research regarding XCSSET, including the ways in which it has adapted itself to work on both ARM64 and x86_圆4 Macs, as well as other notable payload changes. Initially reported as a malware family, in light of our recent findings it is now classified as an ongoing campaign. The larger steps, we feel, provide better mouse movement on a large (Full HD) screen.Last year, we first found XCSSET, which targeted Mac users by infecting Xcode projects. The 8 pixel actions are already defined in iRed Lite. In the Mouse Control layer of iRed Lite, we also changed the basic mouse movement keys from 4 pixel to 8 pixels movements. Further mouse control is not possible unless the layer is changed using the Menu button on the remote (standard iRed Lite functionality). Once VLC launches, iRed Lite automatically switches its layer setting to the VLC layer and the remote button functions are remapped to new functions tailored to VLC.

In use, once the Finder window appears displaying the list of available movies, the cursor control and OK keys on the remote can be used to open the required movie with the default application (VLC in our case). The double-click on the left key is also potentially available to activate some other script or action if required.) (The double click feature for letf/right cursor movement is largely superflous as the single-click left rights keys can be pressed multiple times or held down for larger cursor movements. To use this script with iRed Lite, we have included it on the Mouse Control layer activated by double clicking the right key on the remote, in place of the original "Right 8' (move right 8 pixels) Action. Once the cursor is positioned in the centre of the screen, it is then simple to zoom in and open the required Finder window, and set its bounds to fit nicely in the visible portion of the screen. This is not essential, but it looks nice. Then, it is possible to precisely move the cursor to the centre of the screen.īy combining diagonal and left/right movement, as per the script below, it is possible to create a diagonal movement with the appropriate angle to suit a 16:9 screen ratio. The strategy to position the cursor in the centre of the screen is to first move it to the top left corner, irrespective of its starting position, to move it to a known location. The numeric keypad has an advantage in that it provides for diagonal cursor movement (via the 1, 3, 7, and 9 keys) in addition to up/down/left/right (via the 2, 4, 6 and 8 keys). An extract from this site is shown below. (We don't have a standard Mac keyboard either.) Fortunately, I found a site which included a diagram of the keyboard with key codes on it.

Although utilities are available to display the key code when you press a key, these would not work for us as there are no physical keys to press. The next issue was to determine the key codes for the keys in the numeric keypad, so they could be used for cursor control.

In our case, our Logitech keyboard doesn't have a numeric keypad so there was no penalty in permanently enabling the cursor control feature via system preferences. Some people were not in favour of this approach, fearing they would lose use of the numeric keybad, although it is possible to turn the feature on and off with 5 presses of the Option key - which could also be done as part of a script, if required. Various sites/blogs suggest use of another Universal Access feature which allows cursor control via the keys on the numeric keypad. This is complicated by the lack native cursor movement commands in Applescript (although they are available with various add-on software). Therefore, a major portion of this script is devoted to positioning the mouse cursor at the exact centre of the screen, prior to zooming in. The position of the zoomed-in portion of the screen is not predictable as it depends on the initial mouse cursor position.
