Malicious attacks from insiders may be rare, but they do happen and often involve accessing resources without authorization or sharing data unauthorizedy.
As opposed to brute-force hackers who exploit exploitable weaknesses for entry, internal bad actors often gain entry through legitimate channels and remain undetected. This could result in data breaching, leakage of sensitive information and production losses that go undetected.
What is an Insider Threat in Cyber Security?
Many companies spend thousands of dollars each year on software to detect and block external threats, yet often overlook internal ones – malicious employees, partners, contractors or vendors who bypass cybersecurity measures and gain access to data in the company network. They could steal sensitive information, download malware onto removable media and destroy or corrupt hard drives resulting in costly repairs and lost revenues resulting in expensive repairs or revenue lost altogether.
Malicious insiders typically pursue financial motives when targeting specific departments within an organization. They can manipulate data, extort money from victims, sell stolen information on darknet markets and even damage an organization’s reputation by disclosing competitive data to competitors in the marketplace.
Lone wolves are individuals acting unsupervised with the sole goal of harming a company, guided by their ambition and driven by personal gain. They use vulnerabilities they find to gain higher privileges to steal data or collaborate with threat actors outside of the company for attacks. Lone wolves represent one of the most lethal forms of insider attacks. Luckily, however, these attempts can be detected using user activity software which monitors access logs, login logs, account changes, endpoint and virtual private network logs for risky activity that tracks risky activity over time.
Types of Insider Threats
Cyber security contains multiple forms of insider threats, namely malicious and negligent attacks. Malicious attacks involve intentional efforts designed to cause harm while negligent attacks tend to come about unknowingly due to lack of cybersecurity awareness among employees.
Malicious insiders can include employees, former employees, contractors or business associates with access to an organization’s data and computer systems. Such individuals could be motivated by financial gain, revenge or exposure of company secrets; other emotional factors may play into their motivation, such as jealousy or envy.
Negligent insiders include current or former employees who violate cybersecurity policies, such as clicking on phishing links and downloading malware, or individuals who do not properly secure their devices (for instance bringing home hard drives containing sensitive information but leaving it in their car). Unfortunately these incidents can be difficult to track and prevent; however zero trust network technologies and cybersecurity training may help minimize such errors, while content protection solutions that link classification policies can also provide multiple factor authentication protection against mistakes.
How to Detect an Insider Threat?
An insider threat arises from users with authorized access to your organization’s networks, applications and databases. They could include current employees, third-party contractors or former employees whose access was never taken back away – any person authorized to gain entry can pose this kind of danger; their legitimacy makes them harder to detect.
Malicious insiders could be looking for financial gain, an adversarial relationship against the company or to conduct espionage against it. Their activities could range from stealing trade secrets and selling them off, or exposing personally identifiable patient data – each having significant repercussions for an organization.
Collusional threats represent another type of malicious insider threat, in which an internal individual works together with an outside threat actor to launch attacks against their company. Such attacks typically involve theft of intellectual property and/or computer system disruption. To detect this activity requires sophisticated monitoring tools that are capable of detecting anomalies and alerting administrators as soon as any occur; user behavior analytics, network and database monitoring and continuous vulnerability management may all help detect these potential issues quickly and nip them in the bud quickly.
Why are insider threats dangerous?
Malicious insider threats are capable of stealing data, destabilizing systems and destroying equipment – wreaking havoc for an organization by costing millions in lost revenues, legal fees and reputational damage – not to mention compromising employee trust which may reduce productivity further still.
Insider attackers may be motivated by financial gain, revenge, dissatisfaction or boredom with their job or simply wanting a change in circumstances. Psychologists who study insider attacks believe those responsible possess Machiavellian tendencies, narcissism and psychopathy – characteristics shared among perpetrators.
Insiders working in tandem with external actors to breach organizations are known as collusive threats. Such actors could include competitors, nation states or criminal organizations and can steal intellectual property, customer details, employee records and confidential data before selling it off on darknet markets – this type of attack being more prevalent among industries that store a great deal of data.
Insider Threats Attack history
Internal attacks tend to receive less media coverage than external ones; yet the damage they can do often goes undetected. Such damage may include intellectual property theft, data breaches, sensitive information leakage, production losses and diminished investor and customer confidence – to name but a few potential dangers.
Insiders may include current or former employees, third-party contractors, vendors or anyone with legitimate access to an organization’s networks and digital assets – this can include both independent attackers as well as coordinated attacks.
Malicious insiders act for various motives, such as financial gain, revenge or making themselves known in order to achieve personal gain. Unfortunately, these attackers can often go undetected due to not leaving an easily detectable trail of evidence behind.
Unintentional insiders are individuals who are unaware they are committing an attack against their employer. Hackers use psychological manipulation techniques to convince these insiders to download malware, open an attachment in a phishing email, divulge confidential information on social media, download malware onto compromised machines used by insiders, escalate privileges, infect other systems and cause lasting damage to both reputation and financial health of businesses.
What Are Characteristics of an Insider Threat?
Employee or business associate who misuse their authorized access to sensitive data or privileged accounts of a company can pose an internal threat, making detection more challenging as traditional security measures tend to focus on external threats. Furthermore, since these individuals already possess some level of authorization they do not need to bypass firewalls or security measures to obtain information that could lead to theft of intellectual property or theft of trade secrets.
Malicious insiders could be seeking to profit or gain competitive edge by selling confidential information to competitors or hacking groups, or they could simply have personal vendetta against their employer that they need to vent.
Careless insiders, on the other hand, can unintentionally expose an organization to threat by accidentally clicking on an insecure link or downloading pirated software containing malware. They could also be careless in other ways such as leaving their laptop unlocked or allowing family members to use work computers without authorization. By monitoring behavioral indicators rather than following every anomalous employee action you can eliminate intention from the equation and reduce likelihood of insider attack.
Insider threat detection and prevention
External attacks tend to get all of the headlines, like Stuxnet virus and Eastern European gangster hacking; however, insider threats are just as deadly and may cause greater damage due to having legitimate access to an organization’s cyberassets – making them harder for traditional perimeter-based security systems to detect.
Careless insider threats occur when employees unwittingly expose enterprise systems to attacks by means of phishing, malware and stolen credentials. Additional forms of careless insider threats could include downloading unapproved software containing hidden malware, as well as multiple attempts at accessing servers and devices containing sensitive data.
Malicious insiders can range from opportunists looking to exploit their access, to disgruntled employees seeking revenge or punishment, or hackers working for competitors. An ex-employee from a medical center downloaded patient data onto a USB drive within hours after leaving his employment and this caused the business to lose customer trust as well as its ability to acquire new clients – at great financial cost in terms of remediation fees, legal expenses and lost sales revenue.
How To Protect Against an Insider Attack?
Cybersecurity teams may be too focused on blocking attacks from outside that they ignore internal threats – an alarming risk when considering that insider threats account for 34% of breaches.
An employee using their legitimate access to hack into the company’s systems and steal data for unapproved use constitutes an insider threat. This may be intentional or accidental; either way it could come as either an act of malice or simply carelessness on behalf of their employer; disgruntled employees seeking revenge could exploit opportunities to sell data or disrupt rival companies as insider threats.
Malicious insiders, commonly known as moles, work alongside external hackers to gain entry to an organization and steal its data. This may involve current employees or third-party partners with high access privileges working together.
Careless insiders refers to employees who unwittingly expose the system to risks by clicking on suspicious links or leaving devices unprotected – this can be costly for companies as regulators punish them and any brand damage from an internal breach is costly for any brand.

The Pawn
These employees can be persuaded to commit malicious actions such as disclosing user credentials to hackers or downloading malware. Often driven by greed, revenge, or personal gain – such employees could also act alone without collaboration from other staff members.
Pawns may include employees who fall for spear-phishing emails and disclose their password to people posing as IT personnel, often unaware of the possible repercussions such as identity theft.
Malicious insider threats can create havoc for businesses by engaging in acts such as sabotage, data corruption, fraud and intellectual property theft. Because these insider threats know more about your systems, procedures, policies and users than outside attackers they often have access to more sensitive and confidential data than external attackers; an example would be an angry former employee introducing malware onto his former employer’s network.
The Goof
Malicious insiders, also known as turncloaks, abuse privileged access to gain financial or malicious gain or cause havoc within an organization. For instance, this might involve an employee selling confidential data to competitors, or an ex-employee introducing harmful malware into the system. These types of insiders pose particular danger as they possess intimate knowledge of corporate systems, policies and users – making them even more dangerous.
Negligent employees know about security and IT policies but fail to abide by them, increasing risks to the organization. Examples include exposing sensitive data to hackers by piggybacking through secure entry points; misplacing or losing portable storage devices with sensitive information; or refusing requests to install updates.
Protecting both physical and logical assets requires developing comprehensive information security policies, while employing tools like Privileged Access Management (PAM) and User Behavior Analytics (UBA) to detect suspicious or abnormal activity.
The Collaborator
A collaborative insider threat is defined as any current or former employee, contractor, vendor, or business partner with legitimate user credentials who misuses access to cause damage to networks, systems and data. They may carry out these attacks either unwittingly or intentionally.
Spear phishing, social engineering or any number of other methods may be employed to induce them into taking malignant actions. An insider threat might take the form of an employee unwittingly downloading malware onto their workstation or an ex-employee releasing confidential data to competitors or criminal associates of their employer.
Malicious insiders pose particular threats as they are familiar with enterprise systems, procedures and policies, system versions and vulnerabilities as well as any abnormalities they encounter in these systems. Security teams should monitor these users with equal diligence as external attackers; for instance they should check for excessive downloads or requests to access systems they rarely or never use in an effort to detect suspicious insiders.
The Lone Wolf
An insider threat refers to anyone unauthorized accessing sensitive data or systems without proper credentials, which could include current and former employees, contractors, business partners and third-party vendors.
An insider threat may take the form of either an internal fraudster or collaborator; however, there also exist lone-wolves operating independently who pose particular danger since they often possess privileges such as system or database administration.
Lone wolves may act out of personal grievance or just for attention-seeking purposes by sharing the results of their attack publicly. One hacker who breached Capital One leaked customers’ private data via GitHub and then boasted about their work via social media; such incidents serve as a reminder for CISOs to monitor employee behavior and identify anomalies in order to protect employees and detect threats before it’s too late.
Examples of Insider Threats
There are various types of insider threats, and each must be approached differently in order to stop them from harming your company and increasing cyber attack risks. Malicious insiders could include former employees seeking revenge or disgruntled current employees as well as hackers with access to legitimate system credentials.
Negligent insiders often unwittingly expose sensitive information by sending sensitive business documents to an improper recipient or clicking on malicious links in phishing scams. While aware of security policies, these individuals often choose to ignore them putting the company at unintended risk. Unauthorized software installation such as malware or password sniffing programs are other telltale signs that an insider threat exists as these tools could expose passwords, user names and login credentials for hacking groups to exploit.
