In August 2023, NGNSYS, LLC, with headquarters in Houston, TX, received a call from a small company that assists other businesses with their online presence and marketing. This incident serves as a vivid reminder of the ever-present threat of cyber attacks, particularly the increasingly sophisticated tactics employed by cybercriminals. It highlights the importance of Houston cybersecurity for businesses of all sizes.

The Incident: From Innocent Click to Compromise

The company’s CEO contacted us after noticing that several computers were suddenly experiencing significant slowdowns. Upon discussion, the CEO revealed that this issue began shortly after he received an invoice from an old vendor. Trusting that he owed no money, he clicked on a link to open the invoice. To his surprise, the link did not direct him to a webpage—the CEO eventually closed the tab, assuming the website was simply down. Unfortunately, that single click had opened the door for malware into the company’s systems.

Despite having a technical background and a belief that their cybersecurity measures were adequate, the CEO was unaware that small companies are increasingly targeted by attackers. Within a week, the malware had spread to every device in the organization, actively capturing sensitive login credentials for the company’s online banking, accounting software, and social media accounts.

At NGNSYS, our Houston cybersecurity company responded swiftly. Our cybersecurity engineers jumped into action, quickly identifying and neutralizing the malware on the affected devices. We directed the company to change all login credentials from a secure, known-good device and to implement two-factor authentication (2FA) immediately. Our team then discovered additional online threats that the attackers had infiltrated in an attempt to gain access to the company’s customers by embedding malware in the files shared with them. Fortunately, we detected this before the malware could spread.

The Frequency of Cyber Attacks

The unfortunate reality reflected in this incident is not uncommon. Approximately 43% of cyber attacks target small businesses, highlighting that these organizations are increasingly viewed as low-hanging fruit by cybercriminals. The cost of a cyber attack on a small or medium-sized business can reach upwards of $200,000, with many organizations struggling to recover fully.

At NGNSYS, we take calls like this on a near-weekly basis—underscoring the need for every business to re-evaluate and strengthen its Houston computer security defenses.

Understanding Phishing Attacks

The primary method that initiated this incident was a phishing attack. Phishing is a type of cyber attack where perpetrators impersonate legitimate entities to trick individuals into providing sensitive information. This can be done through emails, messages, or even phone calls that appear convincingly authentic.

Statistics show that over 80% of reported security incidents involve some form of phishing, making it one of the most prevalent threats facing organizations today. As such, it’s imperative for businesses to educate their employees on recognizing these scams.

How to Protect Against Phishing Attacks:

1. Education and Training: Regularly inform employees about the nature of phishing attacks and the tactics attackers may employ to deceive them. Simulated phishing exercises can help identify vulnerabilities.
   
2. Email Filters: Utilize advanced email filters that can identify and block phishing attempts before they reach employees’ inboxes.
   
3. Verify Requests: Encourage employees to verify any requests for sensitive information through secondary channels, especially when dealing with financial transactions.
   
4. Use 2FA: Implement two-factor authentication for all accounts. Even if credentials are compromised, 2FA provides an additional layer of security.
   
5. Regularly Update Software: Ensure that all software, including email clients and anti-virus programs, are kept up to date to protect against the latest known vulnerabilities.

Implementing a Strong Cybersecurity Posture

Following the incident, NGNSYS instituted a comprehensive Defense in Depth strategy for the company. This proactive security approach involves layering various security measures to create a robust defense against potential threats. Key components of a Defense in Depth strategy include:

1. Network Security: Firewalls, intrusion detection systems, and secure network architecture.
   
2. Endpoint Protection: Antivirus and anti-malware solutions on all devices.
   
3. Access Controls: Implementing least privilege access models to limit who has access to what data.
   
4. User Education: Ongoing security awareness training for all employees.

As a leader in Houston IT management, NGNSYS understands the importance of a proactive security approach to protect against evolving cyber threats.
