What Is Security Threats and Its Types

Security threats are attacks aimed at stealing data and disrupting technology-dependent businesses, whether the result of rapid technological growth, human error, or malicious intent.

Cyberattacks may involve malware, phishing attacks, Man-in-the-middle (MitM) attacks and denial of service attacks; as well as hacktivism or malicious insider activity.


Computer security threats are defined as actions or events enabled by vulnerabilities that could lead to the theft, loss or corruption of data or systems; it can also damage an organization’s reputation and financial standing. Common cyber threats include ransomware, phishing attacks, DDoS attacks, data breaches and malware.

Cyberattacks pose serious threats to businesses, with cyber attacks increasing rapidly each year. Some incidents target large corporations while others affect small and midsized enterprises – the damage estimated for such attacks could reach $10 trillion by 2025!

Computer hackers are always looking for new ways to steal, annoy and harm their victims. Security threats use various attack techniques – hacking into networks or exploiting vulnerabilities in software or infrastructure – in order to gain unwarranted entry and gain unauthorized access, giving attackers access to sensitive information or disrupt operations and control infected systems for further attacks.

Viruses, worms, spyware and trojans are some of the most prevalent types of malware. They utilize various tactics to evade antivirus detection such as encrypting or compressing their code; code obfuscation or steganography techniques may also be employed to hide their presence from antivirus programs.

Drive-by downloads represent another cybercrime threat type, where cybercriminals inject malware onto websites and wait for users to visit them in order to steal sensitive information such as login credentials or install malicious software onto endpoints.

Criminals typically prefer targeting employees within an organization as targets of cyberattacks. An insider threat occurs when one or more current or former employees accesses company networks in an attempt to access, steal data from, or expose confidential information – either accidentally or deliberately. An employee could carelessly access company networks while creating or exposing confidential data that could pose threats – this type of attack can come from within and/or from without.


Ransomware attacks involve hackers encrypting files and demanding payment in exchange for a decryption key, often business-critical data. While earlier ransomware attacks targeted files like.doc,.xls,.pdf,.jpg and zip archives only, modern variants now target database, website, office SQL taxCAD virtual desktop files as well as backup files which may prevent their recovery later on. Additionally these attacks can even delete backups files to prevent restoration later.

Cybercriminals often target businesses for financial gain and to obtain intellectual property theft. Once obtained, this data can either be sold on the dark web for profit or used to commit identity theft, sabotage and information extortion crimes.

Companies should create an in-depth cybersecurity strategy in order to protect operations from threats, as well as minimize their impacts. This should include threat modeling techniques that identify and prioritize security vulnerabilities across both digital and physical environments. Organizations must also develop policies for handling the aftermath of security incidents such as alerting customers and authorities as well as recovering systems and data quickly and safely.

Although malware, phishing and ransomware remain among the primary threats to cybersecurity, other issues may come from insiders or vulnerabilities in operating systems or software. Malicious insiders who seek to obtain data or damage systems pose a real danger for business security, so educating employees on how they can protect themselves against these dangers is critical. Operating system vulnerabilities and applications vulnerabilities pose yet another potential risk to enterprise cybersecurity. Zero-day vulnerabilities, which remain unpatched or have been discovered but not addressed by their developers, pose an especially severe threat as hackers exploit them to install malware or launch other forms of attacks. Hackers frequently target open-source CMS websites like WordPress in their search for such vulnerabilities.


Cyber attacks present an ever-increasing threat to organizations and individuals alike. Attackers could utilize malware, ransomware, data breaches or any number of cybercrimes aimed at disrupting operations and compromising confidential data to launch attacks against private businesses, government agencies or even critical infrastructure – with results often catastrophic for both.

Malware refers to any form of malicious software, from computer viruses and Trojan horses to spyware that can harm or steal sensitive data without user knowledge. Attack types range from novice script kiddies using ready-made threat toolkits through to professional operators; hackers also pose significant threats; these individuals often target organizations for political or ideological purposes.

Phishing is a form of cyberattack characterized by sending fraudulent emails with malicious attachments or links, often disguised to look like legitimate bank emails, credit card statements and other official messages from trusted institutions like banks or credit card companies. Phishing attacks often include fake domains for added realism. Hackers may weaponize these attachments further by adding code which captures credentials used to gain entry to corporate systems and networks.

Social media attacks often target specific individuals or groups by infecting websites they frequently access, while drive by download attacks involve downloading malware onto users’ devices when visiting compromised websites, often without their knowledge.

Insider threats pose an existential risk to any organization. Employees who share confidential data inappropriately with outside parties, click on suspicious links, install applications they shouldn’t or engage in unapproved behavior are common sources of insider threats, while contractors, third-party vendors or business partners with existing access may pose additional threats.

Identity Theft

Social engineering enables criminals to exploit user weaknesses in security protocols and gain access to sensitive data, including names, addresses, login credentials, Social Security numbers and credit card details. Identity theft has become an enormously prevalent threat to all companies of all sizes – particularly financial companies due to their vast amounts of customer information stored.

Cybercriminals use web threats to access a company’s intellectual property, including corporate strategies, product designs and technologies that could make an attacker rich or take control of rival organizations or even governments.

Computer security threats come in various forms, from viruses and worms to Trojans and spyware – collectively referred to as the CIA triad. But when considering these potential breaches in security, remember that threats do not equal vulnerabilities; rather, threats represent potential breaches while vulnerabilities can actually compromise it.

Security threats frequently involve theft of personal or organizational data, most often through phishing emails that use false identities to gain access to passwords, bank details and other sensitive data stored on systems. Meanwhile, cyber criminals increasingly resort to malware infections in computers or mobile phones by encouraging users to download malicious games that contain viruses that infiltrate devices with viruses and malware.

Man-in-the-middle (MitM) attacks involve secretly intercepting and altering communications between two parties who believe they are communicating directly, such as Wi-Fi eavesdropping, session hijacking and email interception.

Insider Threats

Insider threats differ from hackers by accessing legitimate means to gain entry. An insider threat could be anyone, such as an employee, third-party contractor, former worker with access privileges still intact or an ex-employee whose access privileges haven’t been terminated – anyone who gains entry has access to your company network and data and could use that access against you and cause irreparable harm.

Malicious insider threats are employees who act maliciously for financial or other personal gain, often by leaking sensitive information, disrupting business operations or engaging in other cyberattacks against their company. Furthermore, such employees could sell information or intellectual property owned by the organization to third parties.

Negligent insiders may not realize that their behaviors pose a security threat to their organization. Their neglect could include misplacing a portable storage device containing company data or failing to update passwords as part of cybersecurity hygiene protocols; or more intentionally by using unsecure devices to gain entry to company networks and bypassing IT policies for accessing confidential or sensitive data.

Security leaders can use data from various sources to construct profiles of individuals. By using financial instability or other indicators as criteria for potential insider threats, they can determine if certain circumstances indicate they may become an insider threat. For instance, when employees suddenly increase access rights while simultaneously disclosing financial pressure they face increases the risk rating and allows security teams to take appropriate actions against any threats within. They then can closely monitor this person for signs of cyberattack or suspicious activities during off-hours – often telling signs that an insider threat might be active within.
