botnets
A botnet is a collection of computers, each known as a “bot,” that are infected with malicious software and controlled as a group by a “bot herder.” Botnets can be used to launch attacks, send spam, and commit fraud. They are often used without the knowledge or permission of the computers’ owners.
Botnets are created when bot herders infect computers with malware that allows them to take remote control of the computers. The bot herder then uses the botnet for various criminal or malicious activities.
Botnets can be used to launch denial-of-service attacks, in which the bots flood a target website or server with requests, overwhelming it and preventing legitimate users from accessing the site. Botnets can also be used to send spam or phishing emails. And, botnets are sometimes used to commit click fraud, in which the bot herders artificially inflate the number of clicks on online ads to generate revenue.
Botnets can be very large, with some bots containing millions of computers. However, botnets can also be small, with only a few hundred or thousand bots.
large botnets are usually created by well-resourced and organized criminal groups, while small botnets are often created by individual hackers or small groups.
It is estimated that there are tens of millions of computers around the world that are part of botnets.
Botnets are a serious problem because they can be used to launch powerful attacks, commit fraud, and spam people. They also put the computers in the botnets at risk of being used for these activities without the owners’ knowledge or consent.
There are a few things you can do to protect your computer from being infected with botnets. First, keep your operating system and software up to date. This will help close any security holes that bot herders can exploit to take control of your computer.
Second, use a good antivirus program and keep it up to date. This will help detect and remove any malware that is installed on your computer.
Third, be careful about the emails you open and the links you click. Don’t open email attachments from people you don’t know, and be suspicious of links in emails, even if they look legitimate.
If you think your computer has been infected with malware, run a scan with your antivirus program and then change all your passwords. You should also contact your ISP to let them know that your computer has been compromised.

social engineering
“Social engineering” is a term used to describe an array of malicious activities carried out by cyber criminals. The goal of social engineering is to trick individuals into divulging sensitive information, such as passwords or financial data, that can be used to gain access to systems or commit fraud.
Social engineering attacks are successful because they exploit human weaknesses, such as the natural tendency to trust others and the desire to be helpful. By preying on these tendencies, attackers are able to obtain the information they need to bypass security measures and gain access to sensitive data.
There are a variety of social engineering attacks, but some of the most common include phishing, pretexting, and baiting.
Phishing is a type of social engineering attack that involves sending fraudulent emails or text messages that appear to be from a legitimate source, such as a company or financial institution. The messages often contain links or attachments that, when clicked, install malware or redirect victims to a fake website designed to steal their personal information.
Pretexting is another common social engineering tactic that involves an attacker creating a false story or scenario in order to obtain personal information from their target. For example, an attacker may pose as a utility company employee and call their target to say there is a problem with their account. The attacker will then ask for personal information, such as a social security number or credit card number, in order to “verify” the account.
Baiting is a social engineering attack that uses physical media, such as USB drives or CDs, that contain malware or other malicious content. The attacker leaves the media in a public place, such as a parking lot or library, in the hopes that someone will find it and insert it into their computer. Once the malware is installed, the attacker can gain access to the victim’s system and steal sensitive information.
Social engineering attacks are becoming more prevalent as cyber criminals increasingly target individuals, rather than organizations. While the best defense against social engineering attacks is education and awareness, there are also a number of technical solutions that can help to mitigate the risk.
Some of the best practices for protecting against social engineering attacks include:
-Never click on links or download attachments from suspicious emails or text messages
-Be wary of unexpected or unexpected requests for personal information
-Do not provide personal information to someone who you do not know
-Do not insert unknown USB drives or other media into your computer
-Keep your antivirus and anti-malware software up to date
