During malware analysis, an investigator finds that a suspicious process is injecting code into a legitimate system process (e.g., explorer.exe). Which technique is being used?
2Refer to the exhibit. An investigator is examining a disk image using TSK. The output from 'fls' shows the directory structure. What is the significance of the entry 'V/V 113-128-1: $OrphanFiles'?
3You are a forensic analyst investigating a suspected malware infection on a Windows 10 workstation. The user reports that the system has been slow and that unexpected pop-ups appear. You have acquired a memory dump and a disk image. During analysis, you find a suspicious process named 'svch0st.exe' running with PID 4567. The process has loaded several DLLs, including 'wininet.dll' and 'ws2_32.dll'. You also find that the process has an active TCP connection to an external IP address 203.0.113.5 on port 4444. In the disk image, you find an executable file at C:\Users\Public\svch0st.exe with a creation date that matches the start of symptoms. The file's hash is not in any known malware database. You decide to perform dynamic analysis by running the file in a sandbox. However, the sandbox environment has no network connectivity. The executable runs but does not exhibit any malicious behavior. What should you do next to determine if the file is malicious?
4Based on the exhibit, what is the most likely indication of malware persistence?
5You are investigating a Windows 10 workstation that exhibits slow performance and frequent pop-ups. The user reports that the system started acting strangely after installing a 'PDF Converter' from an email attachment. You suspect malware. You have captured a memory dump using FTK Imager and a network capture during the infection. In the memory dump, you find a suspicious process 'conhost.exe' running from a non-standard location (C:\Users\Public\Temp). The process has an open handle to a file named 'config.ini' in the same directory. The network capture shows periodic HTTPS connections to 'malicious.com' on port 443 from the workstation's IP. Using Volatility, you extract the process's command line: 'conhost.exe -hidden -log C:\Users\Public\Temp\output.log'. Which of the following is the BEST immediate course of action to contain the threat and preserve evidence?
