This logic has been utilized in a decompiler that allows a final full review of the files used in this malware. It is called several times throughout the script, and is used to deobfuscate hex strings throughout the script. One of the most interesting functions found right away is the decoding function built into the script. Now that we have both the parent script and the embedded script, we can work on disassembling them, to see what each does. This is a new trick for OSAMiner, compared to previous versions we have seen, and makes automated analysis of the malware even more difficult. That, combined with the knowledge of Apple's magic strings at the beginning and end of an AppleScript, allow us to identify the second run-only AppleScript hidden in this file. This file is a little more difficult to analyze, however, a little digging will uncover some hex code in this file. This line is using do shell script to call the com.apple.4V.plist script in the ~/Library/LaunchAgents/ directory.Īs it turns out, com.apple.4V.plist is not a Property List file, but a run-only AppleScript file. However, line 13 is what is especially interesting in this script, because it starts us down the path to truly analyzing this malware. ![]() The repeated use of osascript is highly unusual, which draws attention here, and also gives us the name OSAMiner as this is using Open Scripting Architecture scripts to accomplish its goals. The array in lines 10-14 is very telling. This file is simple, but gives away a key file used in these cryptojacking attacks. plist file extension, only one is a legitimate Property List file, so we'll start there. While several of the files associated with OSAMiner are Property List files, with the. Ttps://pijnpillen.Analysis of the Embedded Run-Only AppleScript Express mode has been designed with commuters in mind, when they may want to quickly tap and pay at a turnstile to access rail, for example, rather than hold up a line due to the need to go through further identity authentication. Newton, Ioana Boureanu, and Liqun Chen.Īccording to the paper, the 'vulnerability' occurs when Visa cards are set up in Express Transit mode in an iPhone's wallet feature. On Thursday, academics from the UK's University of Birmingham and University of Surrey revealed the technique, in which attackers could bypass an Apple iPhone's lock screen to access payment services and make contactless transactions.Ī paper on the research, "Practical EMV Relay Protection," (.PDF) is due to be published at the 2022 IEEE Symposium on Security and Privacy, and has been authored by Andreea-Ina Radu, Tom Chothia, Christopher J.P. ![]() UK academics have uncovered mobile security issues in Visa and Apple payment mechanisms that could result in fraudulent contactless payments.
