​ + + Patcher Ransomware Attacks macOS, Encrypts Files Permanently Posted on February 23rd, 2017 by Security researchers yesterday on a new ransomware for Mac, which calls itself 'Patcher.' The file-encrypting ransomware program finds its way onto macOS systems through BitTorrent websites, masquerading as an Adobe Premiere CC or Office 2016 patcher. Intego's malware research team has updated its definitions to detect all components of the ransomware, identified as OSX/Filecoder and OSX/Filecoder.fs. What is the Infection Vector?

A torrent claiming to contain a patcher for Adobe Premiere CC 2017 or Office 2016 is the only delivery mechanism known so far. Macs running OS X 10.11.x El Capitan and macOS 10.12.x are at risk. Patcher was found on the bittorrent site seedpeer[.]euPatcher does not appear to be concerned about where it runs or if any security software is present. The application is signed with a key that is not signed by Apple.

With the recent KeRanger attacks focused on OS X, we explain exactly what malware and ransomware are and answer an age old question - do Macs need antivirus.

Codesign -dv /Users/intego/Desktop/Office 2016 Patcher.app Executable=/Users/intego/Desktop/Office 2016 Patcher.app/Contents/MacOS/Office 2016 Patcher Identifier=NULL.prova Format=app bundle with Mach-O thin (x86_64) CodeDirectory v=20100 size=507 flags=0x2(adhoc) hashes=11+3 location=embedded Signature=adhoc Info.plist entries=22 TeamIdentifier=not set Sealed Resources version=2 rules=12 files=14 Internal requirements count=0 size=12 The bundle identifier 'NULL.prova' was found in another application, named 'prova,' which is similar in appearance. Progress window, step 2 of 3 By the time the window shows step 2/3, an infected Mac will see its desktop loaded with text files. Of course, the progress window is just there to delay the user while all the files are encrypted in the background. Even if the application is quit at this point it will be too late, because when the text files appear on the desktop all of the contents in the Users folder is already encrypted. When the window shows step 2/3, it's already done; step 3/3 never comes and the application just sits there indefinitely. Any new data created while Patcher is running will not be encrypted by the ransomware.

Patcher appears to focus only on data that was present when the application was first started. The original data that was encrypted is deleted using rm, Patcher then attempts to wipe the free space on the drive with diskutil to make sure the original data is really gone. Luckily, the author made a mistake in the ransomware: It tries to execute /usr/bin/diskutil, however the path to diskutil in macOS is /usr/ sbin/diskutil. This mistake may give a user the chance to recover some of the deleted data by using tools such as Data Rescue. If the ransomware is discovered promptly, which shouldn't be a problem as the numerous text files on the desktop are a solid indicator that something is wrong, and the Mac is shut down, data recovery may have a chance. The longer the Mac is powered on, the greater the chances are the deleted files are overwritten. It is also possible to interrupt Patcher simply by quitting the application.

Simply scroll through the list until you find the arrow you want to insert, double-click it and then click 'Close.' Where do i find a thin arrow symbol in excel for mac?. To make the most out of symbol insertion, select a font that supports a lot of character sets, such as Arial Unicode MS. From this window, you can insert any symbol from fonts installed on your computer, including a wide variety of arrows.

Patcher is very slow, taking a good 30 seconds to encrypt a 250MB video file, so it will need a decent amount of time to encrypt a typical user folder, which can be hundreds of gigabytes. If the user suspects the application is not working or is not what it claims to be, it can be closed and the encrypting of data will stop. Where Does Filecoder Install? Filecoder is a stand-alone application that does not install files on the system to keep itself alive after a restart.

It simply takes your user home folder and encrypts everything in it. The application appears to disable itself, so it cannot be launched again. When it's done disabling itself, it goes after any mounted network volumes and connected external drives. It leaves the system folder, library and applications folders alone, going only after files in the Users folder. As soon as Patcher runs, the user will see text files popping up on the desktop and in other user home folders, with names like 'README.txt' and 'DECRYPT!txt.' Opening these text files will present the following information: NOT YOUR LANGUAGE? USE What happened to your files?
