Botnets, Cybercrime, and Cyberterrorism: Vulnerabilities and Policy Issues for Congress
Order Code RL32114 Botnets, Cybercrime, and Cyberterrorism: Vulnerabilities and Policy Issues for Congress Updated January 29, 2008 Clay Wilson Specialist in Technology and National Security Foreign Affairs, Defense, and Trade Division Botnets, Cybercrime, and Cyberterrorism: Vulnerabilities and Policy Issues for Congress Summary Cybercrime is becoming more organized and established as a transnational business. High technology online skills are now available for rent to a variety of customers, possibly including nation states, or individuals and groups that could secretly represent terrorist groups. The increased use of automated attack tools by cybercriminals has overwhelmed some current methodologies used for tracking Internet cyberattacks, and vulnerabilities of the U.S. critical infrastructure, which are acknowledged openly in publications, could possibly attract cyberattacks to extort money, or damage the U.S. economy to affect national security. In April and May 2007, NATO and the United States sent computer security experts to Estonia to help that nation recover from cyberattacks directed against government computer systems, and to analyze the methods used and determine the source of the attacks.1 Some security experts suspect that political protestors may have rented the services of cybercriminals, possibly a large network of infected PCs, called a “botnet,” to help disrupt the computer systems of the Estonian government. DOD officials have also indicated that similar cyberattacks from individuals and countries targeting economic, -
1186 B.C.E. the Trojan War Greece
1186 B.C.E. The Trojan War Greece The events in the myth of The Judgement of Paris started a period of war called the Trojan War, in which the city of Troy and its allies fought the citystate of Sparta and its allies. Most of what we know of the Trojan War comes from epics such as Homer’s Iliad and O dyssey, but there is evidence that the Trojan War was a real event; the problem is that we don’t know exactly how much of what is described in the Iliad is true. For example, the Iliad features Gods and Goddesses not present in modern society or belief, as well as people that may have been idealized as war heroes. The following is what we know about the events of the Trojan War from the Iliad. Menelaus, the king of Sparta, was so angry that Paris had taken his wife that he set out to wage war with Paris and the city of Troy. To do so, he sent out for certain people to help, such as Odysseus, the hero of the Odyssey, and Achilles, who a seer said the war would not be won without. The Greeks first attacked nearby kingdoms that were supplying Troy, destroying the Trojan economy, killing Trojan hero Hector and looting spoils of war. However, the Greeks couldn’t break down the wall that surrounded Troy, so Odysseus devised a plan now known as the Trojan Horse. The Greeks hid inside a giant wooden horse that they tricked the Trojans to let inside their walls. -

The Process of attempting to gain or successfully gaining, unauthorized access to computer resources Who is a Hacker? In the computer security context, a hacker is someone who seeks and exploits weaknesses in a computer system or computer network. History of Hacking Began as early as 1903: Magician and inventor Nevil Maskelyne disrupts John Ambrose Fleming's public demonstration of Guglielmo Marconi's purportedly secure wireless telegraphy technology, sending insulting Morse code messages through the auditorium's projector The term “Hacker” originated in the 1960’s at MIT A network known as ARPANET was founded by the Department of Defense as a means to link government offices. In time, ARPANET evolved into what is today known as the Internet. -

Enisa Etl2020
EN From January 2019 to April 2020 Spam ENISA Threat Landscape Overview The first spam message was sent in 1978 by a marketing manager to 393 people via ARPANET. It was an advertising campaign for a new product from the company he worked for, the Digital Equipment Corporation. For those first 393 spammed people it was as annoying as it would be today, regardless of the novelty of the idea.1 Receiving spam is an inconvenience, but it may also create an opportunity for a malicious actor to steal personal information or install malware.2 Spam consists of sending unsolicited messages in bulk. It is considered a cybersecurity threat when used as an attack vector to distribute or enable other threats. Another noteworthy aspect is how spam may sometimes be confused or misclassified as a phishing campaign. The main difference between the two is the fact that phishing is a targeted action using social engineering tactics, actively aiming to steal users’ data. In contrast spam is a tactic for sending unsolicited e-mails to a bulk list. Phishing campaigns can use spam tactics to distribute messages while spam can link the user to a compromised website to install malware and steal personal data. Spam campaigns, during these last 41 years have taken advantage of many popular global social and sports events such as UEFA Europa League Final, US Open, among others. Even so, nothing compared with the spam activity seen this year with the COVID-19 pandemic.8 2 __Findings 85%_of all e-mails exchanged in April 2019 were spam, a 15-month high1 14_million -
