12/9/2023 0 Comments Winrar vs 7zipIt is also a similar type of file archive and file compressor which is developed by the Eugene Roshal and is one of those applications which create Rar file natively. It is a file archive and compressor which is developed by the Corel co-operation and is compatible with the windows system and Mac OX S. ![]() It is an open source file archive and not only reads the files of its own format but can also read the files of the other formats. for the compression of the files and is released in the year 2007 for the windows desktop. It is the next version of the PKZIP and is used for the similar function i.e. ![]() It is used for archiving and compression of files. It is the software which is written by Phil Katz and is marketed by the PKWARE Inc. This compression of files not only makes them of smaller size but also frees the space from the hard disk and makes the working speed faster There are many software and applications which are used to compress the files. ![]() The computer performs its various functions using hard drive and if the hard drive has less free space the computer will take longer to process the things out and also takes more time than normal to write the files on hard disks and to start up the windows. Using the incident response data, update logging and audit policies to improve the mean time to detect (MTTD) and the mean time to respond (MTTR).What is the Difference between Pkzip, Securezip, 7zip, Winzip and WinrarĬomputer is a machine in which we can not only write documents and files but also store these files documents in the hard drive. Determine the initial vector abused by the attacker and take action to prevent reinfection through the same vector. This may reveal additional artifacts left in the system, persistence mechanisms, and malware components. Reset passwords for these accounts and other potentially compromised credentials, such as email, business systems, and web services. Investigate credential exposure on systems compromised or used by the attacker to ensure all compromised accounts are identified. Isolate the involved hosts to prevent further post-compromise behavior. Prioritize cases that involve personally identifiable information (PII) or other classified data. Initiate the incident response process based on the outcome of the triage. Check the `` and `_line` fields to determine what triggered the encryption. Backup software can use these utilities. Investigate if the file was transferred to an attacker-controlled server. If the password is not available, and the format is `.zip` or the option used in WinRAR is not the `-hp`, list the file names included in the encrypted file. Decrypt the `.rar`/`.zip` and check if the information is sensitive. Check if the password used in the encryption was included in the command line. Investigate other alerts associated with the user/host during the past 48 hours. Examine their executable files for prevalence, whether they are located in expected locations, and if they are signed with valid digital signatures. Investigate the script execution chain (parent process tree) for unknown processes. These steps are usually done in preparation for exfiltration, meaning the attack may be in its final stages. Encryption can be used to hide information that is being exfiltrated from detection or make exfiltration less apparent upon inspection by a defender. Compressing the data can help obfuscate the collected data and minimize the amount of data sent over the network. # Investigating Encrypting Files with WinRar or 7zĪttackers may compress and/or encrypt data collected before exfiltration.
