However, existing manual and heuristic OS X malware detection techniques are not capable of coping with such a high rate of malware.

With the increasing market share of Mac OS X operating system, there is a corresponding increase in the number of malicious programs (malware) designed to exploit vulnerabilities on Mac OS X platforms. More concerningly, ANTI shows how one can use well-known methods to “resurrect” old attacks. In other words, we show using ANTI that implementation gaps in current tools for dynamic analysis can be exploited to allow binaries to bypass them. Our extensive evaluation also demonstrates that ANTI successfully circumvents detection from state-of-the-art detection methods. This significantly compounds the challenge of binary analysis.

Specifically, ANTI introduces an anti-hooking method targeting Windows binaries, where hooks applied by state of the art debuggers are removed and injects its code in other processes.
We showcase this by presenting a new framework (ANTI), which automates the procedure of integrating anti-debugging and anti-VM in the binary. The debugger and the malware have the same privileges, so the attacker may manipulate the address space that the debugger operates to bypass detection. In this work, we illustrate how the Windows architecture impedes the work of debuggers in the analysis of armoured binaries.

Beyond the malicious uses, software vendors seeking to preserve the intellectual property rights of their products often resort to similar methods to deter competitors from gaining intelligence from the binaries or prevent customers from using their products without unauthorization. In essence, the malware needs to adopt a “defence in depth” paradigm. determining whether the malware is being executed in a VM, or using a debugger prior to payload execution).
However, the malware may incorporate anti-virtual environment (VM) and anti-debugging countermeasures (e.g. This allows the investigator to manipulate the code execution path and environment to develop an understanding of the malware’s internal workings, aims and modus operandi. By verifying the positive and negative functions of the proposed structure, it was validated that the structure accurately provides real-time file access monitoring function, the monitoring function resource is sufficiently low, and the file access monitoring performance is high, further confirming the effectiveness of the proposed structure.ĭynamic malware analysis involves the debugging of the associated binary files and the monitoring of changes in sandboxed environments. With this structural feature, real-time monitoring is possible for all file accesses, and malicious attackers cannot bypass this file access monitoring function.
The proposed structure has five components, with a kernel module interrelated to the application process. In this paper, a structure to monitor user access to important files in real time is proposed. Thus, the service manager or data owner cannot determine real-time unauthorized modification and leakage of important files by malware. However, current operating systems provide only file access control techniques, such as SELinux (version 2.6, Red Hat, Raleigh, NC, USA) and AppArmor (version 2.5, Immunix, Portland, OR, USA), to protect system files and do not provide real-time file access monitoring. To address this problem, the security requirements for post-detection and proper response are presented, with emphasis on the real-time file access monitoring function. Because of this, there are false positives, so the tool assigns a certainty field for each item.Obfuscation and cryptography technologies are applied to malware to make the detection of malware through intrusion prevention systems (IPSs), intrusion detection systems (IDSs), and antiviruses difficult. Since sometimes the first result is expanded in a non-existent file within a SIP-protected area, I wanted to get the rest of those expanded paths. Most publicly available scanners stop once they discover the first case of a vulnerable dylib without expanding the rest of the rpaths. The reason behind creating this tool was because I wanted more control over the data Dylib Hijack Scanner discovered. With the active discovery function, there’s no more guesswork if an executable is vulnerable to dylib hijacking! The tool also calls out interesting files and lists them instead of manually browsing the file system for analysis. Boko Application Hijack Scanner for macOSīoko.py is an application scanner for macOS that searches for and identifies potential dylib hijacking and weak dylib vulnerabilities for application executables, as well as scripts and application, may use that have the potential to be backdoored.
