NEW QUESTION # 62
What kind of malware uses encryption, data theft, denial of service, and possibly harassment to take advantage of a victim?
  • A. Ransomware
  • B. Rootkit
  • C. Worm
  • D. Keylogger
Answer: A
Explanation:
The kind of malware that uses encryption, data theft, denial of service, and possibly harassment to take advantage of a victim is ransomware. Ransomware is a type of malware that encrypts the victim's files or blocks access to their system, and then demands a ransom for the decryption key or the restoration of access. Ransomware can also threaten to expose or delete the victim's data if the ransom is not paid. Ransomware can cause significant damage and disruption to individuals, businesses, and organizations, and can be difficult to remove or recover from. Some examples of ransomware are CryptoLocker, WannaCry, Ryuk, and REvil.

NEW QUESTION # 63
What is an example of an attack vector for ransomware?
  • A. Performing DNS queries for suspicious domains
  • B. Performing SSL Decryption on an endpoint
  • C. Phishing emails containing malicious attachments
  • D. A URL filtering feature enabled on a firewall
Answer: C
Explanation:
An example of an attack vector for ransomware is phishing emails containing malicious attachments. Phishing is a technique that involves sending fraudulent emails that appear to come from a legitimate source, such as a bank, a company, or a government agency. The emails typically contain a malicious attachment, such as a PDF document, a ZIP archive, or a Microsoft Office document, that contains ransomware or a ransomware downloader. When the recipient opens or downloads the attachment, the ransomware is executed and encrypts the files or data on the victim's system. The attacker then demands a ransom for the decryption key, usually in cryptocurrency.
Phishing emails are one of the most common and effective ways of delivering ransomware, as they can bypass security measures such as firewalls, antivirus software, or URL filtering. Phishing emails can also exploit the human factor, as they can trick the recipient into opening the attachment by using social engineering techniques, such as impersonating a trusted sender, creating a sense of urgency, or appealing to curiosity or greed. Phishing emails can also target specific individuals or organizations, such as executives, employees, or customers, in a technique called spear phishing, which increases the chances of success.
According to various sources, phishing emails are the main vector of ransomware attacks, accounting for more than 90% of all ransomware infections12. Some of the most notorious ransomware campaigns, such as CryptoLocker, Locky, and WannaCry, have used phishing emails as their primary delivery method3 . Therefore, it is essential to educate users on how to recognize and avoid phishing emails, as well as to implement security solutions that can detect and block malicious attachments. Reference:

NEW QUESTION # 64
To create a BIOC rule with XQL query you must at a minimum filter on which field in order for it to be a valid BIOC rule?
  • A. causality_chain
  • B. threat_event
  • C. endpoint_name
  • D. event_type
Answer: D
Explanation:
To create a BIOC rule with XQL query, you must at a minimum filter on the event_type field in order for it to be a valid BIOC rule. The event_type field indicates the type of event that triggered the alert, such as PROCESS, FILE, REGISTRY, NETWORK, or USER_ACCOUNT. Filtering on this field helps you narrow down the scope of your query and focus on the relevant events for your use case. Other fields, such as causality_chain, endpoint_name, threat_event, are optional and can be used to further refine your query or display additional information in the alert. Reference:

  • A. Python 2 and 3 with specific XDR Python libraries developed by Palo Alto Networks
  • B. Python 2 and 3 with standard Python libraries
  • C. Python 3 with standard Python libraries
  • D. Python 3 with specific XDR Python libraries developed by Palo Alto Networks
Answer: C

Live terminal uses the Python interpreter embedded in the Cortex XDR agent, which is based on Python 3.7.4. The standard Python libraries are the modules that are included with the Python installation and provide a wide range of functionalities, such as operating system interfaces, network programming, data processing, and more. You can use the Python commands and scripts to perform advanced tasks or automation on the endpoint, such as querying system information, modifying files or registry keys, or running other applications.
