INTRODUCTION
In recent years, there has been substantial growth in electronic attacks over the Internet, and it is expected that there will be new strategies in the future.Cyber-attacks are a set of tactics carried out by individuals with the ability to exploit gaps in electronic systems and networks, often with the intent of damaging systems or accessing and viewing sensitive information [1][2][3][4][5][6].These attacks can be carried out from a variety of different websites (unnatural links or fake) or malicious applications and are known to affect a wide range of different types of industries [7][8][9][10][11][12].Every form of electronic attacks poses a major threat to the security of companies, institutions and even individuals because they can lead to the theft of data and information from their devices.Moreover, these attacks are characterized by the ability to disrupt services, business processes, and other things within the digital environment.Consequently, it is important for organizations to adopt a set of practical tactics to address this issue in order to prevent it from having a harmful impact on their operations in the digital environment.Organisations or institutions depend on monitoring, detection, prevention and response techniques, which are the most widely used methods to prevent cyber-attacks.They are continually seeking to develop these strategies and make them more effective and able to know the behaviour of electronic attacks.Cyberattacks can be described as malicious activities that target computer systems, networks, and devices over the Internet, intending to endanger or damage sensitive information [13][14][15][16][17][18][19][20].Computer systems are among the most desirable systems to be controlled by unauthorized persons because the information included within these systems is very necessary to them [21].These attacks can originate from a single individual or a group of individuals who may be motivated by financial gain, political activity, or even personal motives.Figure 1 shows that the costs of cybercrime will rise to more than $23 trillion by 2027.
A variety of tactics are utilised to execute cyberattacks, including viruses, malware, phishing attempts, and denial-of-service (DoS) assaults [23] [24].Viruses and malware are powerful tools that have the practical ability to infect computer systems, disable their services, steal sensitive information and destroy necessary files.These methods are often spread through emails, instant messages, or malicious websites.One of the most dangerous operations is phishing, which is a social engineering attack that tricks users into revealing login credentials, credit card numbers, or other sensitive information.During this procedure, it is possible for unauthorized individuals to gain control of all sensitive information.These attacks can take the form of fake emails, phone calls, or websites that appear to come from a delegated source (see Figure 2).In addition, there are other harmful assaults, which are the DoS attacks, which are the most common electronic attacks that overload a website or network with traffic, making it unavailable to users in the digital environment.These attacks are executed utilising a network of compromised computers, which are commonly referred to as bots.The bots collaborate to produce a large volume of traffic and influence the flow of information between users.These attacks have devastating consequences for individuals, organisations, and institutions.For individuals in the cyber environment, cyberattacks can lead to the theft of sensitive information, such as passwords and financial information, or the loss of essential files from computers.As for institutions or organisations, they may be exposed to large financial losses, reputational damage, and even legal liability.To counter these cyberattacks, following the soundest practices for online security, such as utilising strong passwords, avoiding emails from suspicious parties, and keeping the software and operating systems up-to-date is essential.In addition, institutions and organisations must implement cybersecurity criteria, such as firewalls, antivirus software, and intrusion detection systems to protect their networks and data from any cyber-attack.With the rise of cyber threats in the digital world, it is essential for both individuals and organizations to take preventative measures against cyber-attacks and malware.This can be accomplished by keeping up-to-date with the most recent dangers and employing efficient security measures while devising appropriate strategies to thwart them [25][26][27][28][29]. Section 2 of this article will cover the five most sophisticated cybersecurity threats.

TOP FIVE EVOLVING THREATS
Cyber-attacks are complicated procedures as they use advanced tools and techniques to penetrate systems and computer networks.These attacks have the ability to bypass firewalls and antivirus programs in order to steal sensitive information [31][32][33].Examples of advanced cyber threats include advanced persistent threats (APTs), ransomware, and zero-day exploits .The 5 most famous threats that exist now are as follows: -Ransomware Attack A ransomware attack is one of the most advanced types malicious cyber-attacks, where the attacker performs a series of actions with the purpose of encrypting the victim's computer files or the entire system and demands payment in dollars or another currency in exchange for providing the victim with a decryption key or code.Ransomware attacks can be delivered through multiple channels, including phishing emails, social engineering, and exploit kits, which are favoured by the attacker.The loss of information or data can have a significant impact on its users, leading to potential financial losses or damage to their reputation.Therefore, they are forced to follow the instructions of the attacker and satisfy them in order not to lose their data.Maintaining regular backups of data, implementing protective software, and providing proper user training to prevent falling prey to phishing scams are crucial.The years 2021 and 2022 witnessed a significant development in ransomware, as a large number of these attacks appeared, and these attacks are still developing until now in February 2023 in infiltrating systems, encrypting them, and stealing sensitive information.Figure 3 demonstrates a sample of a hacker encrypting a victim's data and providing a deadline.If the victim fails to yield to the hacker's requests, all their files will be completely wiped out.-IoT Attacks Through the IoT environment which encompasses various devices embedded in the environment of things such as lights, washing machines, televisions, etc.Many devices connect to the Internet on a daily basis to communicate with each other and share data that is controlled by users.In recent years, IoT devices have seen numerous attacks ranging from physical attacks on IoT devices to social engineering attacks on IoT devices.Through these attacks, users' devices are fully controlled, data is infiltrated, all the movements of these users are viewed and misused for malicious purposes, as well as their movements are monitored within the digital environment.The attacker can gather information about the victim's behaviour, find out full details about him/her, and exploit it to carry out malicious operations against the user, destroy his reputation, or steal money.In addition, social engineering is widely employed to make attacks against users.In this type, the attacker exploits the trust relationships established between users and IoT devices to obtain sensitive information from the devices and pass it on to them or others without the command or approval of these users.Internet of Things devices is the most vulnerable devices to hacking and cyber threats.In general, every smart and digital device that transmits data via the Internet, for instance, laptop computers, is vulnerable to threats and electronic crimes in order to access sensitive information and control user behaviour.Figure 4 shows the statistics of the types of attack on devices in the IoT environment.-Cloud Attacks Cloud computing is the modern era of new technologies, as it revolutionised the physical world to store all data and files in large sizes.Large and small companies always seek to back up their files and data in the digital cloud.In addition, the digital cloud is utilised to transfer files easily between companies or individuals.On the other hand, cloud computing is characterized by its low cost and high efficiency in storing and transmitting data, but this also increases the chances of data security breaches.The primary motivation for compromised data security is a lack of encryption and authentication and incorrect configuration of cloud settings.As a result, it is necessary to execute mechanisms and tactics in maintaining many considerations for cloud security, protecting all files and data, as well as preserving sensitive information.Cyber-attacks take different forms targeting cloud computing systems and infrastructure.These attacks seek to find vulnerabilities that would allow hackers to gain access to sensitive information stored in the cloud and disrupt the regular operation of applications and services that rely on cloud computing.Companies frequently resort to digitisation by converting all data into digital data and storing it in computers and cloud computing in order to deal with it efficiently [36].Through this process, electronic attacks are generated to control the cloud, unauthorized access to cloud resources, data breaches, denial of service attacks, and access to all files stored within this cloud.To prevent cloud attacks, it is crucial to execute strong security measures, including access controls, encryption, monitoring and detection systems, and regularly assess the security of cloud environments.

-Phishing Attacks
Phishing attacks are one of the most expected electronic crimes on the Internet, where the attacker tries to get sensitive information such as passwords, credit card numbers, and other personal information from individuals in the digital environment.Usually, these attacks include the use of fake emails that seem to come from a trustworthy source, such as a well-known site, well-known platform, or bank, in order to reassure the victim of the incoming messages.These messages contain fake links designed to look real but intended to steal the victim's information without their knowledge.Moreover, in these attacks, well-designed malware is employed to infect computer systems or applications that run immediately once installed with the possibility of stealing sensitive information or controlling the victim's computer.To safeguard against these attacks, individuals should be very cautious of unwanted emails (Spam) or fake messages, especially those that ask for personal information or contain suspicious links.It's also crucial to use robust passwords and regularly monitor bank and credit card accounts for suspicious activity.Besides, utilising antivirus software and keeping all software and operating systems updated can assist in preventing phishing attacks and other types of cybercrime. -

Cryptocurrency and Blockchain Attacks
Cryptocurrency and blockchain attacks refer to various forms of cyberattacks targeting cryptocurrency wallets, exchanges, and blockchain networks [37][38][39][40].Phishing is one of the most common styles of cryptocurrency attacks.Attackers send scam emails or messages to cryptocurrency users, often impersonating an authorised source, in an attempt to steal their login credentials or other sensitive information.Utilising malware, where attackers infect computers or mobile devices with malware prepared to steal cryptocurrency wallets or other sensitive data.In addition to attacks on individual users, cryptocurrency exchanges and wallets can also be targeted by hackers who utilise distributed denial-of-service (DDoS) attacks to flood the network and access sensitive information.Blockchain networks can be targeted by attackers trying to take control of the network, known as a 51% attack (see Figure 5), or exploiting vulnerabilities in the code to steal or manipulate data.To safeguard against cryptocurrency and blockchain attacks, users should use robust passwords, enable two-factor authentication, and keep their software and operating systems contemporised.Exchanges and other service providers must also utilise robust security measures, such as encryption, firewalls, and intrusion detection systems.Likewise, the community as a whole can work to enhance the security of blockchain networks by conducting regular code audits and executing the most useful practices for network governance and security.

CONCLUSIONS
Sensitive information is the primary mark for attackers who want to steal, manipulate, or delete it from the victim's devices.The process of stealing this information takes place through several methods of attack and exploitation of individuals or institutions in order to complete the interests of the attackers.Cybercrimes are constantly growing, and modern strategies are being utilised to commit crimes operating computers and the Internet, such as hacking, phishing, identity theft, cyberstalking, and online fraud.These crimes cause significant harm to individuals and institutions and exploit them in order to take large sums of money and publish private information to the public.Unfortunately, these crimes are challenging to verify due to the global and unspecified nature of the Internet.Therefore, it is preferable to use artificial intelligence techniques that have a significant role in analysing the behaviour and practices of malicious software.In addition, practical prevention and response to cybercrime require a combination of technological solutions, legal frameworks and international cooperation.
