For the CoinMiner malware, please write a short paragraph based on the given background and website info:
CoinMiner – Trojan
CoinMiner is a cryptocurrency miner family that typically uses Windows Management Instrumentation (WMI) to spread across a network. Additionally, it often uses the WMI Standard Event Consumer scripting to execute scripts for persistence. However, the malware’s capabilities may vary since there are multiple variants. CoinMiner spreads through malspam or is dropped by other malware.

Coin Miner is a malware type that uses the hardware elements of the victim’s PC to mine cryptocurrencies. Most often, crooks who control such coin miner virus (Monero (XMR) or (Litecoin an example), as they are the easiest for mining. They can use the software that is similar or even completely repeats the one used for legit mining, but with a key difference - people whose hardware is used never agreed for this.…

File Managementarrow_forwardFor the ZeuS malware, please write a short paragraph based on the given background and website info: ZeuS – Trojan ZeuS is a modular banking trojan that uses keystroke logging to compromise credentials when a victim visits certain banking websites. Since the release of the ZeuS source code in 2011, many other malware variants have adopted parts of its codebase, which means that incidents classified as ZeuS may actually be other malware using parts of the original ZeuS code. https://www.cisecurity.org/insights/blog/top-10-malware-december-2022 Zeus malware can give attackers full access to infected machines. While the original Zeus variant primarily utilized man-in-the-browser keyloggers to gain access to an infected computer’s banking credentials and other financial information, many forms of the Zeus virus can also be used to add CryptoLocker ransomware to an operating system or add infected computers to a botnet to perform distributed denial-of-service (DDoS) attacks.

- What’s the correct answerarrow_forwardAn example of a host-based intrusion detection system is the tripwire software. This programme scans the system's files and directories and alerts the administrator of any changes. For each file examined, it uses a secure database of cryptographic checksums and compares them as they are scanned. It must be configured with an authorised change list and a list of files and directories to examine. It can enable new entries to be added to log files, but it cannot change existing ones. What are the advantages and disadvantages of using such a tool? Think about the decision of which files should be verified and which should only be inspected seldom. Take into account the time spent setting up the application and keeping track of the outcomes.arrow_forwardGive an example of how a full denial of service attack on a user (in which the user gets no response from the computer) results in a significant issue for that user. Another example is offered in which a 10% denial of service (that is, the user's computation advances but at a 10% slower pace than normal) is a significant issue for that user. Illegal access to a computer system may result in a 10% denial of service attack against legitimate users of that computing system. If so, how would you proceed?arrow_forward
- 104. Like a virus, it is also a self-replicating program. The difference between a virus and it is that a worm does not create copies of itself on one system: it propagates through computer networks. a) Keylogger b) Worm c) Cracker d) None of thesearrow_forwardHacktivists often use DDoS attacks against organizations that they perceive as being opposed to them. This includes not only government but also journalists, publications, and human rights groups. Google's parent Alphabet has stepped up to help with thwarting DDoS against these groups. Since 2016 Project Shield has thwarted DDoS attacks against hundreds of websites in over 80 countries. These attacks were directed at websites in order to silence important information. Project Shield was offered for free to journalists, small publications, human rights groups, and others. But Google is doing that from its own initiative at a relatively high cost. Should there instead be a tax on computer hardware and/or software that goes towards a fund that is then used for organizations like this to have permanent DDOS mitigation?arrow_forwardSuppose that you are a computer virus writer; hence, you know that you need to store a copy of the code for your virus inside the virus itself. Moreover, suppose you know that a security administrator is also aware of this fact and will be using it to detect the presence of your virus in operating systems files. Explain how you can hide the embedded copy of your virus so that it is difficult for the security administrator to find itarrow_forward
- The tripwire program is an example of a host-based intrusion detection system. This tool examines files and folders on the system and notifies the administrator of any changes. It employs a protected database of cryptographic checksums for each file reviewed and compares them as they are scanned. It must be set with a list of files and directories to check and changes allowed. It can allow adding new entries to log files but not changing old ones. What are the benefits and drawbacks of employing such a tool? Consider the issue of selecting which files should be checked and which should be reviewed rarely. Consider the time spent configuring the application and monitoring the results.arrow_forwardTo what extent can a single individual organize the launch of a DDoS attack?arrow_forwarda computer virus that embeds itself in an executable.
