Best practices for protecting your business from insider threats

An insider threat is a cybersecurity risk coming from within an organization. This risk often arises when employees, contractors, vendors, or partners with proper access misuse it to harm the organization’s networks, systems and data. Whether intentional or not, such actions threaten the confidentiality, availability and integrity of the organization’s systems and data.

In the 2023 Insider Threat Report by Gurucul, it is revealed that over 70% of organizations believe that they are moderately to highly susceptible to insider threats. Over the past year, more than half of the surveyed organizations have faced at least one insider threat, with 8% encountering over 20 incidents.

According to the 2023 Cost of Insider Risks Global Report by Ponemon Institute, the average cost to address and mitigate the fallout of an insider threat that lasts for 91 days is $18.32 million. The report also highlights that only 13% of insider threats could be mitigated within 31 days.

Types of insider threat

Insider threats within organizations can manifest in various forms. These threats include:

1. Unintentional Threats: Caused by negligence or accidents, these threats arise from insiders who disregard security protocols or make errors, like sending sensitive information to the wrong recipient or losing data storage devices.
2. Intentional Threats: This involves malicious insiders who deliberately harm the organization for personal gain or due to grievances. Actions can range from data leaks to sabotage.
3. Collusive Threats: These occur when insiders collaborate with external actors, like cybercriminals, to compromise the organization. This threat often involves fraud or intellectual property theft.
4. Third-Party Threats: Often involving contractors or vendors, these threats stem from those with some level of access, who might directly or indirectly pose a risk to the organization.

Case examples of insider threat

High-profile cases of insider threats have demonstrated their significant impact on organizations. While some cases may not have immediate monetary implications, they still harm the company’s reputation and customer trust.

For instance, Tesla faced a data leak where two former employees disclosed over 75,000 employees’ personal information. The information compromised included personal and contact details, employment records and sensitive financial data. The two perpetrators also disclosed details about customer bank accounts, Tesla’s production secrets and feedback on its Full Self-Driving features. Tesla took legal measures against the individuals responsible, but the breach left lasting implications for its data security reputation.

In May 2022, Qian Sang, a then-Yahoo research scientist, downloaded Yahoo’s AdLearn product information. Sang transferred about 570,000 pages of intellectual property to his devices. This occurred shortly after he accepted a job offer from The Trade Desk, a rival company. Weeks later, Yahoo discovered the data theft. The company then issued Sang a cease-and-desist letter. Yahoo filed three charges against Sang, including the theft of IP.

Microsoft also experienced a security lapse when employees accidentally exposed login credentials in August 2022. The company did not disclose specific details about the systems impacted by the credential exposure. However, had the breach involved the personal data of EU customers, Microsoft would have to pay a substantial €20 million fine under GDPR.

In 2022, Apple initiated legal action against the startup Rivos. The tech giant accused Rivos of systematically hiring its former employees. Apple claimed that Rivos did this to obtain confidential information. At the time, Rivos had hired over 40 of its previous staff, including engineers who allegedly took gigabytes of sensitive data related to Apple’s System-on-Chip (SoC) technology. Apple had developed this SoC technology for over a decade with substantial investment. This technology was reportedly critical to Rivos’ accelerated SoC development. Apple’s lawsuit framed this as a data theft.

Protect your business from insider threats

To combat insider threats, organizations must integrate a series of strategic actions into their security plan. This begins with a comprehensive inventory and classification of data resources throughout the IT environment. The classification includes data stored onsite and in cloud infrastructures. Classifying data allows for the efficient and secure use of information across the organization.

Next, developing a detailed data handling policy is crucial. This policy should dictate how different types of data can be accessed and used and by whom. It’s essential to incorporate a system that flags violations of this policy, which could indicate potential insider threats.

Training employees is also essential in preventing insider threats as it enhances their awareness of security risks, including unintentional ones. Through training, employees better understand company policies and their roles in data security. They learn to recognize signs of potential threats and the correct response to suspected breaches. This reduces accidental security lapses and cultivates a strong culture of security within the organization.

Monitoring systems for signs of insider threats is also key. Implementing solutions like intrusion detection systems, privileged access management systems and user behavioral analytics helps in identifying suspicious activities. Investigating any unusual activities promptly can significantly mitigate risks posed by insider threats.

At C8 Secure, we provide comprehensive services tailored to combat insider threats. Our expertise includes conducting detailed cyber security assessments, vulnerability testing and crafting incident response plans. C8 Secure’s managed Endpoint Detection and Response (EDR) and Managed Detection and Response (MDR) services play a crucial role in mitigating insider threats. These services continuously monitor endpoints and network activity for suspicious behavior, enabling rapid detection and response to potential threats. For example, if an employee attempts to exfiltrate sensitive data via an unauthorized USB device, C8 Secure’s EDR solution would detect this anomalous activity and trigger an alert for investigation.

Similarly, C8 Secure’s managed Security Operations Center (SOC) and Security Information and Event Management (SIEM) services provide 24/7 monitoring and analysis of security events across an organization’s infrastructure. By correlating data from multiple sources, such as user activity logs, network traffic, and application events, C8 Secure’s SOC team can identify potential insider threats that might otherwise go unnoticed. For instance, if a privileged user suddenly starts accessing sensitive resources outside of their normal working hours, the SOC team would be alerted to investigate this anomalous behavior.

C8 Secure’s managed Web Application and API Protection (WAAP) services are also critical in defending against insider threats. These services protect an organization’s web applications and APIs from unauthorized access and abuse, which is particularly important given the growing reliance on cloud-based services. For example, if an employee attempts to exploit a vulnerability in a web application to gain unauthorized access to sensitive data, C8 Secure’s WAAP solution would detect and block the attempt.

Beyond these technical controls, C8 Secure also emphasizes the importance of employee training and policy development in mitigating insider threats. By working with organizations to develop comprehensive security policies and providing targeted training to employees, C8 Secure helps foster a culture of security awareness. This can help prevent unintentional insider threats, such as the accidental exposure of login credentials by Microsoft employees.

Insider threats pose a significant risk to organizations of all sizes and industries. By leveraging C8 Secure’s managed security services, including EDR, MDR, SOC, SIEM, and WAAP, organizations can significantly enhance their ability to detect and respond to insider threats.

The alarming surge of Phishing and how to protect your business

The threat of phishing is escalating. Statista reported that there were over 1.62 million unique phishing sites globally in Q1 2023, over 50% higher than the same period in 2022. On top of that, a 2024 survey involving 500 cybersecurity experts indicates a staggering 94% of organizations have faced phishing attacks.

Almost 80% of organizations faced financial implications due to phishing, with 64% experiencing direct monetary loss. Of these incidents, 74% led to disciplinary actions against employees.

Businesses typically spend about 11 months recovering from a phishing attack. With such implications, phishing has now become the primary method for initiating breaches (16%), surpassing stolen credentials (15%), according to data retrieved by IBM. The 2023 data also revealed that data breaches cost an average of over $4.5 million.

Types of phishing attacks

Phishing attacks come in various forms. Each of these has its own distinct characteristics. Here are some common types:

1. Email Phishing: The most common type, where attackers send fraudulent emails resembling those from reputable sources. These emails aim to trick recipients into revealing sensitive information, such as passwords or credit card numbers.
2. Spear-Phishing: A targeted form of phishing. Attackers personalize emails to specific individuals, often using personal information for authenticity. The goal is to steal data or install malware on the target’s device.
3. Whaling: A specialized spear-phishing attack targeting high-profile individuals like executives. Whaling attacks often involve crafting highly sophisticated emails that address specific business concerns or personal interests of the target.
4. Smishing (SMS Phishing): This type of phishing attack uses text messages instead of emails. Smishing messages often create a sense of urgency, prompting recipients to disclose personal information or click on a malicious link.
5. Vishing (Voice Phishing): Conducted via phone calls. Attackers pretend to be from legitimate organizations, seeking personal or financial information. They often use fear tactics, like threatening legal action.
6. Quishing: This involves the use of fake or manipulated QR codes whereby hackers carry out fraudulent activities, such as malware spreading or taking personal information.
7. Pharming: Here, attackers redirect users from legitimate websites to fraudulent ones. This is typically achieved by exploiting vulnerabilities in DNS servers.
8. Clone Phishing: Involves creating a nearly identical replica of a legitimate email with a safe attachment or link replaced by a malicious one. It often claims to be a resend or updated version of the original.
9. Angler Phishing: Uses social media platforms for attacks. Fraudulent social media posts or messages, often pretending to be customer service accounts, aim to extract personal information from victims.

Well-known cases of phishing

Deepfake video attack

A multinational company recently lost $26 million after a Deepfake fooled employees, fabricating representation of the CFO and others. The scammers convinced the victim to make a total of 15 transfers to five different Hong Kong bank accounts, according to reports. The company attacked has not been identified.

Colonial Pipeline attack

In May 2021, the Colonial Pipeline ransomware attack starkly demonstrated the real-world impact of cyber attacks. The attack disrupted fuel supply across the East Coast of the United States. The breach, which likely began with a phishing email, compromised the company’s business network and billing system. Despite Colonial Pipeline paying about $4.4 million for a decryption key, the ripple effects were far-reaching.

The shutdown, lasting a week, halted the delivery of around 20 billion gallons of oil valued at about $3.66 billion. This incident spiked petrol prices and left over 10,000 petrol stations without fuel even after operations resumed. CEO Joseph Blount, in an interview with The Wall Street Journal, acknowledged the wider economic toll and defended his controversial decision to pay the ransom. This attack ranks as one of the most financially devastating phishing incidents ever.

NotPetya Malware attack

June 2017 saw the onset of NotPetya, a catastrophic cyber attack that rapidly spread across more than 60 countries. Originating as a supply chain attack through Ukrainian accounting software, NotPetya targeted Windows-based systems, encrypting hard drives and demanding ransoms. Unlike typical ransomware, NotPetya, likely a state-sponsored Russian wiper malware, rendered data irretrievable. This caused unprecedented damages exceeding $10 billion. Major companies like Maersk, Merck and FedEx suffered immense losses.

Sony Pictures attack

In November 2014, Sony Pictures fell victim to the ‘Guardians of Peace’ hacking group. The attackers gained access through phishing emails, eventually leaking 100 terabytes of sensitive data. The emails, disguised as communications from Apple, deceived top executives into providing their credentials on a fake website. This breach not only exposed employee and film information but also included a demand to withdraw “The Interview” under threats of violence. The total damages to Sony Pictures from this cyberattack were estimated to exceed $100 million.

Facebook and Google scam

Evaldas Rimasauskas, a Lithuanian man, orchestrated a cunning business email compromise (BEC) scam against Facebook and Google, defrauding them of over $100 million. Between 2013 and 2015, Rimasauskas and his associates created convincing forged email accounts. They pretended to be Quanta Computer, a real vendor for both tech giants. Through elaborately crafted phishing emails containing bogus invoices and contracts, they deceitfully billed millions of dollars. The scam resulted in these companies transferring the funds to Rimasauskas’ sham company accounts spread across multiple countries.

FACC business email compromise attack

In 2016, FACC, an Austrian aerospace manufacturer, was hit by a severe BEC attack. Impersonating the CEO, attackers convinced an employee to transfer roughly $50 million for a fake acquisition project. While $10 million was salvaged at the last minute, the company still suffered significant financial damage and the CEO was subsequently dismissed.

Tips to combat phishing

Phishing poses a significant threat to businesses of all sizes. However, companies can effectively combat this pervasive cyber threat through a blend of technological solutions, employee education and vigilant practices. Here’s what businesses can do to combat phishing:

1. Recognize phishing scams: Stay informed about new phishing techniques and their common features. Regular updates and training can help you identify these threats early.
2. Provide security awareness training: Technical defenses alone can’t stop phishing. Educate employees about phishing dangers and teach them to report suspicious activities. Regular simulated phishing exercises can test and enhance your team’s readiness.
3. Strong passwords and Two-Factor Authentication: Encourage unique, complex passwords for each account and discourage password sharing. Implement two-factor authentication for an added security layer.
4. Heed update alerts: Don’t ignore software update notifications. These updates often contain vital security patches protecting against the latest cyber threats.
5. Be careful with emails and links: Avoid emails and links from unknown sources. Verify links by hovering over them and avoid clicking unless sure of their safety.
6. Avoid unsecured websites: Don’t share sensitive information on websites without HTTPS encryption or a visible security certificate. There is a closed padlock icon on the URL bar when the website has HTTPS certification.
7. Ignore pop-ups: Pop-ups can be phishing attempts. Use ad-blockers to prevent them and avoid clicking on any that slip through.
8. Regularly change passwords: Regularly updating your passwords can prevent ongoing unauthorized access, especially if your accounts have been compromised without your knowledge.
9. Deploy Anti-Phishing tools: Use anti-phishing technologies to block fraudulent sites and emails. Combine desktop and network firewalls for comprehensive protection from external threats.

Safeguard your business against cyber attacks caused by human error

October is Cybersecurity Awareness Month, a dedicated month for the public and private sectors to work together to raise awareness about the importance of cybersecurity. This year’s theme is how to keep yourself cyber safe.

As the world becomes more reliant on digital technology, businesses, both large and small, face a growing risk of cyber attacks. A frequent weak point that attackers target is mistakes made by employees. This blog will outline effective strategies to keep your business safe.

Human error is an ever-present risk in cybersecurity. Whether it’s clicking on a suspicious link, falling victim to a phishing scam, or inadvertently sharing sensitive information, employees can unintentionally open the door to cyber threats.

IBM Security X-Force Threat Intelligence Index 2023 revealed that attempts to hijack threads in emails doubled in 2022 from the 2021 data, which highlights that cybercriminals are exploiting the human error factor within a system. The research also showed that ransomware was the most common attack, accounting for 17% of all incidents. Phishing emerged as the preferred choice for cybercriminals, with over 40% of all attacks employing this deceptive tactic.

Cyber attack cases due to human error

Victims felt the pressure in 27% of cyber attacks. This is why cybercriminals often focus on their extortion efforts. One notable example of such extortion tactics was demonstrated by the digital extortion gang Lapsus$ in early 2022. This group, which had surfaced in December, launched an extensive hacking spree, targeting high-profile and sensitive companies like Nvidia, Samsung, and Ubisoft.

They stole valuable source code and data and leaked it as part of their apparent extortion schemes. Their spree peaked in March when Lapsus$ announced its successful breaches of Microsoft Bing and Cortana source code. The group also compromised a contractor who had access to the widely used authentication service Okta. These attackers, suspected to be based in the United Kingdom and South America, primarily relied on phishing attacks to gain entry into their targets’ systems.

In February 2021, one of Silicon Valley’s oldest and renowned venture capital firms, Sequoia Capital, was hacked. This occurred due to human error. The hackers were able to access the company’s investors’ financial and personal information. The attack succeeded after one of the company’s employees was victim to a phishing email.

In August 2019, Toyota Boshoku Corporation, a subsidiary of Toyota Group in Europe, suffered a massive attack that cost the company almost $40 million. The attackers used a fraudulent fund transfer to steal from the company. They were able to use the funds after posing as a business partner. The hackers then sent phishing emails to the finance and accounting departments of the company.

Effective strategies to combat cyber attacks and human error

Cyber attacks are becoming more sophisticated. As IBM’s report showed, human error remains a significant vulnerability. To safeguard your company’s sensitive data and maintain your reputation, it’s imperative to implement robust cybersecurity measures such as:

1. Comprehensive employee training

The first line of defense against cyber threats is a well-informed workforce. Provide your employees with thorough training on cybersecurity best practices. This should encompass recognizing phishing attempts, understanding password hygiene, and staying updated on the latest threats. Regular workshops and seminars can go a long way in keeping your staff vigilant.

2. Strong password policies

Weak or easily guessable passwords are an open invitation to cybercriminals. Encourage the use of complex passwords with a combination of letters, numbers, and special characters. Implement multi-factor authentication (MFA) wherever possible to add an extra layer of security.

3. Regular software updates

Neglecting software updates can leave your organization vulnerable to cyber threats. Outdated software often contains known vulnerabilities that cybercriminals can exploit. To mitigate this risk, make it a standard practice to ensure that all your applications and systems have the latest security patches. Whenever possible, automate this process to reduce the chance of human error or oversight. By staying up-to-date, you not only enhance security but also benefit from improved software performance and functionality.

4. Robust Firewall and EDR/MDR

A reputable firewall paired with an EDR (Endpoint Detection and Response) or MDR (Managed Detection and Response) solution can help strengthen your prevention and response posture . These tools provide continuous monitoring of network traffic, detecting, and promptly addressing malicious activities. Utilize behavioral anomaly detection to identify unusual user behaviors, which can indicate compromised accounts. It’s crucial to maintain and regularly update these security solutions to adapt to your organization’s evolving needs and the ever-changing threat landscape.

5. Data encryption

Sensitive data is cybercriminals’ favorite target, and data breaches can have severe consequences. To protect your critical information, implement encryption protocols. Encryption ensures that data remains indecipherable to unauthorized individuals without the appropriate decryption keys. By applying encryption both in transit (when data is being transmitted between systems) and at rest (when data is stored), you add an extra layer of security.

6. Incident response plan

No organization is immune to security breaches, so it’s vital to prepare for the worst-case scenario. Developing a comprehensive incident response plan helps you outline the steps to take in the event of a security breach. This plan should encompass communication protocols, strategies for containing the incident, and procedures for recovering from it. Being well-prepared minimizes the impact of a breach and demonstrates your commitment to cybersecurity, instilling trust among stakeholders.

7. Regular security audits

Proactive measures are essential to maintain a secure environment. Regularly conducting security audits and penetration testing helps identify vulnerabilities in your systems before cybercriminals can exploit them. Stay ahead of potential threats by identifying weaknesses and addressing them promptly. This proactive approach enhances your overall security posture. This also makes it more difficult for attackers to find and exploit vulnerabilities.

8. Employee accountability

Employees play a crucial role in your organization’s cybersecurity efforts. Hold them accountable for their actions within the digital landscape. Implement user activity monitoring and enforce strict access controls to prevent unauthorized data access. By doing so, you not only reduce the risk of insider threats but also foster a culture of responsibility and security awareness among your workforce. Employees who understand their role in protecting digital assets become valuable allies in the ongoing battle against cyber threats.

9. Vendor security assessment

If your business relies on third-party vendors or cloud services, like Continent 8, assess their security measures rigorously. Ensure they adhere to high cybersecurity standards to prevent potential vulnerabilities throughout your supply chain.

10. Cybersecurity culture

Building a cybersecurity-conscious culture is essential in safeguarding your organization’s digital assets. It involves instilling a sense of vigilance and responsibility in every employee. Encourage all team members to proactively identify and report any suspicious activities they encounter. Recognize and reward those who diligently follow security protocols, as this reinforces the importance of cybersecurity throughout the organization.

11. Continuous education

Cyber threats evolve rapidly, so it’s crucial to stay informed. Encourage your IT team to prioritize continuous education. This means keeping up-to-date with emerging threats and staying informed about the latest cybersecurity technologies. Investing in ongoing training and professional development empowers your IT professionals to effectively combat new and sophisticated cyberattacks. Knowledge is a powerful defense, and a well-informed team can proactively adapt and strengthen your organization’s security measures.

12. Incident documentation and analysis

When a security incident occurs, responding swiftly and methodically is important. After a security incident, document the event and conduct a thorough analysis. This analysis is a valuable learning tool, enabling your organization to make informed decisions about strengthening its security posture. Implement necessary measures to prevent similar incidents in the future, turning each security breach into an opportunity for growth and improved resilience.
