The word Botnet is formed from the words ‘robot’ and ‘network’. Cybercriminals use special Trojan viruses to breach the security of several users’ computers, take control of each computer and organise all of the infected machines into a network of ‘bots’ that the criminal can remotely manage.
A security header like X-Frame-Options will not protect users against clickjacking attacks that are not using a frame. Content Security Policy. The frame-ancestors directive of Content Security Policy (introduced in version 1.1) can allow or disallow embedding of content by potentially hostile pages using iframe, object, etc.
Similarly, when a criminal is trying to hack an organization, they won't re-invent the wheel unless they absolutely have to: They'll draw upon a common arsenal of attacks that are known to be highly effective, such as malware, phishing, or cross-site scripting (XSS).
A distributed denial-of-service attack may involve sending forged requests of some type to a very large number of computers that will reply to the requests. Using Internet Protocol address spoofing, the source address is set to that of the targeted victim, which means all the replies will go to (and flood) the target.
Passive attacks basically mean that the attacker is eavesdropping. This is in comparison to an active attack, where the intruder attempts to break into the system to access or change data. Even though a passive attack sounds less harmful, the damage in the end can be just as severe if the right type of information is obtained.
A hacker is any person engaged in hacking. The term hacking historically referred to constructive, clever technical work that was not necessarily related to computer systems. Today, however, hacking and hackers are most commonly associated with malicious programming attacks on networks and computers over the internet.
While everyone is vulnerable to phishing, malware or hacking attacks, there are a few key practices that can greatly increase your protection from the majority of instances. Make sure to invest in security solutions to keep your data safe. This even includes choosing strong passwords that can’t be easily guess by computer programs.
The attacks that Lentz is worried about are fileless attacks, also known as zero-footprint attacks, macro, or non-malware attacks. These types of attacks don't install new software on a user's computer, so antivirus tools are more likely to miss them.
MiTM attacks pose a serious threat to online security because they give the attacker the ability to capture and manipulate sensitive information in real-time. The attack is a type of eavesdropping in which the entire conversation is controlled by the attacker.
The pharming attack definition, according to Wikipedia: “Pharming is an attacker’s attack intended to redirect a website’s traffic to another, bogus site. Pharming can be conducted either by changing the hosts file on a victim’s computer or by exploitation of a vulnerability in DNS server software.
Hacking and phishing are related in that they are both ways of obtaining information, but they differ in their choice of methods. A phish, which is ultimately a hack, occurs when a user is baited with an email, phone call, or, perhaps, a text message and tricked into “voluntarily” responding with information.
Anonymous: real spam is sent with spoofed or harvested sender addresses to conceal the actual sender. Mass mailing: real spam is sent in enormous quantities. Spammers make money from the small percentage of recipients that actually respond, so for spam to be cost-effective, the initial mails have to be high-volume.
Spear phishing is an email-spoofing attack that targets a specific organization or individual, seeking unauthorized access to sensitive information. Spear-phishing attempts are not typically initiated by random hackers, but are more likely to be conducted by perpetrators out for financial gain, trade secrets or military information.
Now, virus generally refers to a malicious program that self-replicates but requires some user interaction to be initiated. Spyware. The term 'spyware' is a sub-division of viruses and refers to those programs dedicated to stealing your personal details (logins, passwords, personal info, etc) once they've found a way onto your computer or phone.
A watering hole attack is a security exploit in which the attacker seeks to compromise a specific group of end users by infecting websites that members of the group are known to visit. The goal is to infect a targeted user's computer and gain access to the network at the target's place of employment.
