Cybercriminal activity involves the use of a computer network for the purpose of committing a crime. This can be theft of data, money, or other property. There are many types of cybercriminal activities that occur, from insider threats to DDoS attacks.
Cybercriminals have begun to use phishing as a means to acquire sensitive information. This can include passwords, credit card and banking details. If you receive a suspicious email, you should contact your IT department to verify its legitimacy.
Phishing involves sending emails or SMS messages that are fraudulent. It can be done by a known or unknown sender. The most common phishing schemes include:
Email phishing is a scam that tries to trick people into giving away personal information. Often the email contains a malicious link that redirects the victim to a spoofed website. Alternatively, a phishing message can contain a malware file that installs on the user’s computer.
Another form of phishing is called a man-in-the-middle attack. During this type of attack, a criminal uses two persons to convince another person to give out information.
A DDoS attack, or Distributed Denial of Service attack, is the flooding of a target system with malicious traffic. This overloading of a system causes it to become unavailable to legitimate users.
Although a DDoS attack may be difficult to avoid, there are steps you can take to reduce the chances of a DDOS happening to you. For example, you can segment your network to decrease the probability of a single device causing a DDOS event. Also, geographically distributing servers across the globe may make attacks more challenging.
It’s no secret that a DDoS attack can be very costly, as well as disruptive. These attacks may be used to disrupt services or extract money from unsuspecting website owners. Some attackers will even demand a ransom for stopping the onslaught.
When cyber criminals encrypt data, they do it using a program called ransomware. Generally, they demand a ransom in order to restore access. They hold on to the encrypted data until the money arrives.
One way to minimize the risks of a ransomware attack is to develop a mitigation plan. This is a step-by-step procedure that outlines what to do in case your company is targeted. The plan should also include secure backups.
You should keep your operating system and antivirus software up-to-date. Updating your system prevents malicious software from infecting your computer. Also, you should take precautions against phishing emails. These phishing emails trick you into opening a malicious attachment.
To keep your business safe, you must adopt a zero trust model for your network. In addition, you should train your employees about the Internet.
Insider threats are a major concern for businesses of all sizes. They are increasingly a part of the attack chain, with the number of insider-related breaches increasing each year. While not all insider threats are malicious, if left unchecked, they can lead to a host of issues, from data loss to damaging brand reputation.
An insider threat is a user of a system within an organization. This could be a current employee, vendor, or third party. The individual may have legitimate access to the system, but misuse of that access can have dire consequences.
A typical insider threat scenario involves a former employee trying to gain access to company trade secrets, information, or proprietary technology. These individuals can sell the information, and even use it for nefarious purposes.
DDoS-for-hire services, also known as booter services, enable anyone to launch a destructive denial of service attack. These attacks are often targeted against e-commerce sites, gaming platforms, and educational institutions.
These services are increasingly accessible. Cybercriminals have found ways to advertise illegal DDoS services on underground forums and websites. It’s a business model based on software as a service.
In a coordinated global response, law enforcement agencies have launched ad campaigns targeting individuals who are seeking these services. The ad campaigns are meant to educate the public and deter cybercriminals.
One of the first cases of this kind in the United States was against a Minnesota-based company, Washburn Computer Group. They allegedly paid several DDoS-for-hire services to knock down their websites.
Another group, the Lizard Squad, was famous for performing stunt hacking. They used outages to advertise their services.
