As cybercriminals advance in skill, the frequency and severity of cybercrime significantly rise with each passing year. There are many types of cyberattacks, and many different things can drive them. Nevertheless, it is well known that hackers aim to undermine an organization’s security by identifying and taking advantage of its procedures or infrastructure vulnerabilities.
Any attempt to steal, modify, or destroy data or information systems from computer information systems, infrastructures, networks, or personal computing devices is considered a cyber attack.
Although there are several entry points by which a cybercriminal can compromise a network, most such attacks follow similar patterns. A few examples of common forms of cybercrime are as follows:
- Password Attack
As you might have guessed, a password attack is a cyberattack in which the attacker tries to “crack” the password by speculating on it. A user’s password can be cracked using various techniques, including rainbow tables and brute-force attacks. Naturally, hackers will also try phishing to obtain a user’s password.
Adopting a strong password policy, with the help of a strong username generator like 1Password, is the first line of defense against password attacks. While to find security flaws, penetration tests should also be run. Get a real-time auditing tool that detects and reacts to unwanted login attempts.
- DNS Tunnelling
DNS tunneling is a sophisticated attack method used to gain unauthorized access to a system. As a result of the fact that many organizations don’t attempt to inspect DNS traffic for malicious behavior, attackers can “tunnel” malware into inquiries. It is possible to construct an undetectable, uninterrupted communication channel using malware.
Since DNS tunneling is difficult for standard firewalls and antivirus programs to detect, you will likely need to invest in specialized solutions like TunnelGuard to stop it. If malware is found in malicious DNS queries, automatic activation must be prevented using the methods you deploy.
- MITM Attack
A “man in the middle” (MITM) cyberattack occurs when an adversary takes advantage of a vulnerability to eavesdrop on a victim’s conversations with a third party. “Man in the middle” attacks occur when an attacker tries to disrupt a conversation between two people by inserting themselves. A key element of this attack is that the attacker is eavesdropping on the conversation between the two targets.
In a man-in-the-middle (MITM) attack, both parties believe their conversation is taking place in a safe and confidential environment. They don’t realize that someone other than the intended recipient can edit or access the message before it reaches its destination. Therefore, use a virtual private network (VPN) or wireless access points with strong encryption to shield yourself and your company from man-in-the-middle attacks (VPN).
- Birthday Attack
Birthday attacks can compromise the security of hashing algorithms, which ensure the authenticity of a transmitted message, software, or digital signature. Hash functions take an input message of any length and produce an MD (message digest) of a fixed length that characterizes it uniquely. The “birthday attack” refers to the possibility of discovering two random messages that both hash to the same MD. If the attacker calculates the same MD for his message as the user, the recipient will not be able to tell that the message has been replaced.
- Business Email Compromise (BEC) Attack
A business email compromise (BEC) attack occurs when a hacker sends a malicious email to a specific individual within an organization, typically an employee with access to financial transaction authorization credentials. While being effective, a BEC attack requires considerable planning and investigation. The attacker needs knowledge of the company’s executives, employees, customers, business partners, and potential business partners to extort money from the employee.
Security awareness training is the strongest defense against BEC and other phishing attacks. Employees should be taught how to identify malicious emails, such as those from suspicious domains or those that falsely claim to be from reputable vendors.
- Whale-Phishing Attack
Since CEOs and other high-ranking company officials have access to critical company information, they are prime targets for whale phishing attacks. These individuals may access sensitive company data that could be used in a future assault.
A “whale” victim who downloads ransomware is more likely to pay the demanded sum to avoid drawing negative attention to the attack. Take the same precautions with any phishing attempt to avoid falling for a whale-phishing attack, such as avoiding clicking on unusual links or opening attachments from unknown senders.
- DNS Spoofing
Hackers employ DNS spoofing to fool people into visiting a malicious mirror site. Suppose a user falls for the fraud and provides vital information on the bogus site. In that case, the hacker will have a veritable treasure trove. The hacker may also launch a low-quality website with disparaging or provocative content targeting the rival.
DNS spoofing is a technique used by cybercriminals to deceive their victims into giving up sensitive information by making them believe they are on a legitimate website. Viewing from the visitor’s perspective allows the attacker to execute criminal acts while masquerading as a legitimate business. You may protect yourself against DNS spoofing by maintaining current DNS servers. While DNS servers are frequently attacked, security issues are routinely patched in recent software updates.
- Drive-By Attack
A drive-by attack occurs when a hacker places malicious code on an easily exploitable website. When a user visits the site, the script is automatically executed, potentially infecting their entire computer. This website does not demand any participation or personal information submission.
To avoid being a victim of drive-by attacks, you should always use the latest software available for your devices. Internet users can also use web-filtering software to assess a website’s potential dangers before visiting them.
To construct a successful defense, one must first grasp the nature of the attack. The top eight cyber-security attacks that disrupt and infiltrate networks were discussed in this article. As you can see, there are several ways in which attackers can acquire unauthorized access to vital systems and private information.
Although the precautions adopted to deal with these threats vary, the basics of security do not: You should regularly update your antivirus database, perform frequent backups, establish a least-privilege model in your IT environment, train your staff, use strong passwords, and audit your IT systems for suspicious activities.
