Several cyber-attacks have been reported this year, and according to the Cisco Annual Cybersecurity Report, attackers can now launch campaigns without human help with the emergence of ransomware worms that live on networks. The numbers of security events have increased and they have become more complex.
The term “cyber attack” means that somebody intentionally and maliciously attempts to breach the information system of another person or organization. In recent attacks, data destruction appeared to be the goal as well as an economic objective.
Attacks by malicious actors can have a range of motives, including political activism, but they often aim to gain money or other kinds of economic gain. The following article explains the top types of cybersecurity attacks that will occur in 2021.
Cybersecurity attacks 7 types that are most common
Top 7 cybersecurity threats USA 2021
1.It is social engineering
By exploiting social interactions, social engineering attacks gain access to valuable data. Deception is the basis of every social engineering attack. In social engineering attacks, hackers trick and manipulate their targets into breaching security measures or disclosing sensitive information. Cybersecurity systems cannot stop social engineering attacks, since the target allows the hackers access. We’ve listed social engineering threats as a top threat because experts say the threat is on the rise.
Often, phishing attacks are carried out by sending large amounts of fraudulent e-mails that appear to be from a reliable source to unsuspecting recipients. A fraud email may appear legitimate, but in reality it links the recipient to a malicious file or script designed to grant attackers access to your device to seize control, gather information, or extract data such as financial details, user information, etc.
Besides social media, phishing attacks can also take place through direct messages posted by other members of online communities with a hidden agenda. Phishers can collect information about your work, interests, and activities using social engineering and other sources of public information, which gives them an edge when convincing you that they are not who they claim to be.
More organizations are digitally transforming and increasingly using online collaboration tools in 2020, resulting in an increase in cloud adoption. By 2021, cloud computing will be the defining technology for how companies operate.
Global cloud services market spending is expected to reach USD $1 trillion by 2024, at a compound annual growth rate (CAGR) of 15.7% during the forecast period of 2020 to 2024.
These rapid migrations, however, can expose organizations to a host of security threats and challenges. Vulnerabilities in cloud apps, incomplete data deletion, misconfigurations in cloud storage, and a lack of visibility and control are some of the common cloud service issues that pose cybersecurity risks.
4.Cyber threats such as ransomware pose a serious threat.
You are held hostage by these attacks until you pay a ransom to download your files. Only a small fraction of the ransom fee is lost in the short term. Data loss and lost productivity are two of the most costly damages a business can suffer. Ransomware is one of the top 10 cyber attacks and one of the most popular ways to target businesses. Attacks like these are why 60% of small businesses fail within six months of a cyber breach. The United States doesn’t expect this to change anytime soon. The Department of Homeland Security has noted an increase in ransomware attacks worldwide.
5.Denial-of-Service (DOS) Attack
During a DoS attack, traffic is flooded onto systems, servers, and networks to overload resources and bandwidth. It is this result that prevents the system from processing and fulfilling legitimate requests. Denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks are two types of denial-of-service attacks.
A DoS attack saturates a system’s resources in order to impede service responses. The goal of a DDoS attack is to take down a system from several infected hosts and disrupt the service. This opens the door to multiple attacks on the compromised host.
DDoS and DoS attacks have several types including TCP SYN floods, teardrops, smurf attacks, pings of death, and botnet attacks.
6.Payment processing is one of the common services provided by third parties to retailers.
Thus, they often believe that they are not liable for the actions of third parties. Third-party vendors are not exempt from responsibility if a data breach occurs.
Even if a company does not directly handle personal information-such as social security numbers and credit card numbers-a third party can compromise it. As with the Target malware attack in 2013, hackers are able to steal data through third-party vendors using malware. In case of a data breach, businesses that contract with third-party vendors are still legally liable and required to notify their customers and regulators.
7.Injections of SQL
This occurs when attackers insert malicious code into a server that forces it to deliver protected information by leveraging server query language (SQL). The attacker usually submits malicious code into an unprotected comment section or search box on a website. SQL injection can be prevented by using secure coding practices, such as prepared statements and parameterized queries.
By using parameters as an alternative to directly inserting values, SQL statements can allow malicious queries to be run on the backend. In addition, the parameter is only treated as data by the SQL interpreter, not as code. Click here to learn how to prevent SQL injection through secure coding practices.
Cyber attackers are attracted to passwords due to their widespread use for authenticating access to secure information systems. In addition to gaining access to data and systems such as passwords, an attacker can manipulate the data and control the system.
In order to determine an individual’s password, password attackers use a variety of approaches, including social engineering, gaining access to a password database, and testing the network connection to obtain unencrypted passwords.
Originally, a “brute-force attack” was referred to as a method of guessing passwords in a systematic manner based on all the possible variants and combinations of information.
Dictionary attacks are another method used by cybercriminals to gain access to a computer. By using a list of common passwords, the attacker can try to gain access. Two-factor authentication and account lockout are very useful when it comes to preventing password attacks. Account lockout features can lock out an account after a number of invalid password attempts, while two-factor authentication adds an extra layer of security by requiring the user to enter a secondary code only accessible on their 2FA device(s).
9.Updating software is the beginning of many attacks.
It is for this reason that companies would be in danger of losing data if they don’t keep up with software patches. Two large-scale cyber attacks launched starting in May 2018 illustrate this trend in cyber security. Once attackers learn of a software vulnerability, they can exploit it to launch a cyber attack. The attacks exploited a critical vulnerability in the Windows operating system known as Eternal Blue. The vulnerability was patched by Microsoft two months earlier. Without updating their software, organizations were left vulnerable. An update lapse cost the company millions of dollars.
10.Using outdated hardware
The pace at which software updates are released can make it difficult for the hardware to keep up. As a result, not all cyber security threats come from software. In turn, this exposes companies’ data to risk. As outdated hardware becomes available, more and more devices will not be able to receive patches and security updates. It creates a big potential vulnerability for cyber attacks to target devices with older software. Keeping an eye on this and responding quickly when devices become out of date is important. Maintaining your hardware is no different from keeping your software up-to-date
11.Security threats on mobile devices
Businesses benefit from mobile technology, but they can also be put at risk by cyber security breaches. An organization that suffers a mobile security breach every five times is the conclusion of a recent report.
CONCLUSION Cyber Security Threats
As cyber attacks become more complex and diverse, there is a different type for each nefarious purpose.
As we have mentioned, there are many threats and many tools that can help mitigate cyber risk. In order to manage cyber risk holistically, cyber insurance is imperative. In order to effectively address cyberspace, one needs dedicated expertise. Despite the fact that cybersecurity prevention measures differ according to attack type, good security practices and basic IT hygiene can help to mitigate most of these attacks.
