CPTIA Exam Dumps : CREST Practitioner Threat Intelligence Analyst

Email-bombing refers to the attack where the attacker sends a massive volume of emails to a specific email address or mail server in order to overflow the mailbox or overwhelm the server, potentially causing it to fail or deny service to legitimate users. This attack can disrupt communications and, in some cases, lead to the targeted email account being disabled. Masquerading involves pretending to be another legitimate user, spoofing is the creation of emails (or other communications) with a forged sender address, and a smurf attack is a specific type of Distributed Denial of Service (DDoS) attack that exploits Internet Protocol (IP) and Internet Control Message Protocol (ICMP) to flood a target with traffic. Email-bombing specifically targets email services with the goal of causing disruption by overflowing inboxes.References:CREST CPTIA courses and study guides often include discussions on various attack vectors used by cybercriminals, including email-based threats and their impact on organizational security.

The analyst used Open Source Intelligence (OSINT) to gather information from publicly available sources. OSINT involves collecting and analyzing information from publicly accessible sources to produce actionable intelligence. This can include media reports, public government data, professional and academic publications, and information available on the internet. OSINT is widely used for national security, law enforcement, and business intelligence purposes, providing a rich source of information for making informed decisions and understanding the threat landscape.References:

Employee monitoring tools are primarily used by employers to detect and prevent malicious insider threats. These tools can track activities such as data access, data exfiltration attempts, unauthorized actions, and other behaviors that could indicate malicious intent or pose a risk to the organization's security. While such tools may also incidentally uncover issues like lost registry keys, conspiracies, or stolen credentials, their main purpose is to safeguard against insiders who might misuse their access to harm the organization, steal data, sabotage systems, or engage in espionage.References:CREST CPTIA study materials cover various security measures and tools that organizations can use to protect against insider threats, emphasizing the role of monitoring in detecting and responding to malicious activities by insiders.
