Supply Dropper Mac OS
Symptoms
Symptoms such as these could mean that a device connected to the USB-A , USB-C , or Thunderbolt 3 (USB-C) port on your Mac isn't getting enough power:
- A message says that the device needs more power, the operation can't be completed, or USB devices are disabled until you unplug the device using too much power.
- An operation that requires more power doesn't work. For example, writing to disk requires more power than reading from it.
- The device doesn't turn on or isn't recognized by your Mac.
Solutions

- Shotcut is a free, open source, cross-platform video editor for Windows, Mac and Linux. Major features include support for a wide range of formats; no import required meaning native timeline editing; Blackmagic Design support for input and preview monitoring; and resolution support to 4k.
- Trojan.MacOS.Dropper is a generic name for the dropper components of trojans. The purpose of a trojan is to infect the victim’s system without getting detected or raise any suspicion. Once it achieves that, there are various functions the trojan can have: Exfiltrate data (passwords, contacts, etc.).
- Use your device as a self-powered device or connect it to a powered USB or Thunderbolt 3 (USB-C) hub if possible.
Self-powered devices get power from an electrical outlet or their own battery. Bus-powered devices get power from the device they're plugged into, such as your Mac. - Reduce the total amount of power needed from your Mac by reducing the number of bus-powered devices connected to your Mac, or using more of them as self-powered devices.
- If your device is plugged into another device (such as a display or multiport adapter) as part of a chain of devices, the other device might not be providing enough power or passing through enough power from your Mac. Plug your device directly into your Mac instead.
- Make sure that the port on your Mac and the cable you're using to connect it to your device both support the same or later USB specification as your device. For example, a device designed to support the USB 3 specification might not get enough power when plugged into a USB 2 port or cable.
- Try a different cable, in case the cable that you're using is damaged or defective. If you're using an adapter with your cable, the adapter could also be damaged or defective.
- If your Mac has multiple Thunderbolt 3 ports, connect your device to a Thunderbolt 3 port farthest away from the current port. For example, if your device is connected to the ports on the left side of MacBook Pro, connect to the Thunderbolt 3 ports on the right side.
- If your device has software (such as drivers or firmware) that can be updated, make sure that it's using the latest software from the manufacturer. To get firmware updates for Apple accessories, update your Apple software.
- Make sure that your Mac is awake and started up from the Mac operating system. Some Apple devices can request extra power only when your Mac is awake or started up from macOS.
Learn more about USB power on your Mac
System Information provides additional detail about USB power on your Mac. Connect the USB device directly to your Mac, then select USB from the sidebar in System Information. For each USB device, System Information shows:
- Current Available: The default power provided by the port to which your device is connected.
- Current Required: The power needed by your device.
- Extra Operating Current: Mac computers and Apple displays introduced after 2006, when directly connected to certain Apple devices such as iPhone or iPad, can provide extra power over one or more ports. The Mac or display must be powered on and awake to provide this extra power. A Mac started from the Windows operating system doesn't provide extra power.

Computer users, especially Mac users, should be on the lookout for a dangerous Mac OS X Trojan going disguised as a PDF file that trick users into installing malware, which in return makes their system vulnerable to a remote attack.
Even though it is rare, Mac malware continues to be a burden among unfortunate Mac OS X users who run their systems without any type of anti-malware or anti-virus protection. In recent onslaughts of malware attacks on Macs, it has resulted in the installation of fake security applications much like what on a day-to-day basis for PCs. The latest threat against Macs utilizes a social engineering technique, one of the first we have seen affect a Mac system. This technique basically takes advantage of a trusted and recognizable file, a PDF file in this case, and launches a backdoor attack on the Mac computer.

The generic trojans Trojan-Dropper:OSX/Revir.A and Backdoor:OSX/Imuler.A, known for installing malware on an infected computer, are the culprit of the recent Mac PDF document exploitation. These are Trojan droppers that aide in the exploitation and redirection on Mac computers affected by the malicious PDF file. Basically, after the Trojan dropper-infection is installed from the loading of the malicious PDF file, it launches a backdoor infection possibly by connecting to a malicious source over the Internet. Backdoors carry a heavy payload in the sense that it could allow communication with a remote command-and-control server to be initiated. With such a remote connection, a hacker could infiltrate a system and have unadulterated access to files, personal data or stored passwords. In other words, this exploit could turn into a bad case of 'you no longer exist' or what we refer to as, Identity Theft.

Security researchers have made a discovery that the particular malware laden PDF file contains Chinese language. Commonly, we have seen cases where malware files are written in a language other than English, which sometimes is a concurrence of its creator's origin. It has yet to be revealed where the malicious PDF comes from.
The Mac OS X Trojan PDF file is currently a low risk threat because it does not exactly take advantage of a vulnerability nor does it actually contain a Trojan but rather installs one. Moreover, some security researchers believe that a properly configured Mac computer would be able to mitigate the backdoor installer that is initiated by the malicious PDF file. Clearly, the crosshairs are still sharply focused on Windows systems and Mac computers are just bonus points for relentless hackers that conjure up new malware every day.

Do you ever think or fear that Mac computers will one day face the wrath that PCs have faced with when it comes to malware? If so, what would be the factors to contribute to targeting Mac systems other than a growing population of them?
