Many cybersecurity incidents start with human error. From phishing emails and malicious links to social engineering, cybercriminals often exploit employees’ mistakes and everyday habits to find ways into corporate networks. Recently, Unni, South Korea’s largest platform for plastic surgery and dermatology appointments, was reportedly subject to unauthorized access, resulting in the exposure of users’ personal data, including that of more than 4,000 users from Taiwan. The exposed information reportedly included not only basic details such as names and phone numbers, but also pre-treatment consultation photos uploaded by users, treatment records, and payment information, making the incident significantly more sensitive than a typical personal data breach.
Data security incidents involving a South Korean medical aesthetics platform, a U.S. toy company, and Taiwanese beauty and fashion retailers highlight the growing cybersecurity risks facing businesses. Such incidents can lead to operational disruptions, regulatory liabilities, and other consequences. With the year-end shopping season approaching, businesses in Taiwan should take proactive steps to establish multi-layered cybersecurity defenses.
Email and Endpoint Security to Build the First Line of Defense
As attack methods become increasingly sophisticated, businesses can strengthen their first line of defense across two key areas: email and endpoint security. Secure Mail helps filter malicious emails and suspicious content at the point of delivery, reducing the risk of phishing attacks and malware infiltration. If an attack gets past the email security layer, EDR continuously monitors endpoint activity, detects abnormal behavior, and helps block threats in a timely manner. For businesses with limited cybersecurity resources or facing alert fatigue, MDR services can provide 24/7 threat monitoring and incident response by a professional cybersecurity team, helping organizations identify and address potential threats in real time.
Strengthening Identity and Data Controls to Reduce Internal Data Exposure
Compromised accounts are another common entry point for cyberattacks. Exposed employee passwords and unauthorized remote access can provide attackers with opportunities to launch ransomware or intrusion attacks. Businesses can implement MFA to reduce the risk of unauthorized access even when account credentials have been compromised. Combined with DLP, organizations can also control access to and transmission of sensitive data internally, helping reduce the risk of critical information being exposed.
A comprehensive backup strategy is also essential to maintaining business resilience. It enables organizations to quickly restore critical data and services in the event of ransomware attacks, data corruption, or system failures. Businesses can adopt the 3-2-1 backup principle and establish off-site backup infrastructure to shorten recovery time in the event of malicious encryption or system disruptions, helping minimize the impact on business operations.
Preparing for the Q4 Shopping Season: Moving from Reactive Defense to Proactive Protection
Additional cybersecurity measures may appear to be an added cost for businesses, but compared with the reputational damage and regulatory liabilities that can result from a security incident, proactive security measures can help reduce potential losses. Drawing on 26 years of practical experience in the information technology industry, eASPNet has observed through its work with e-commerce businesses that many organizations place greater emphasis on measures such as endpoint protection and security testing after experiencing personal data breaches. Businesses should therefore shift their approach from responding to incidents after they occur to preventing them in advance, using continuous testing and security measures to identify and mitigate potential risks early.
For most e-commerce businesses, the year-end shopping season is not only a critical period for driving sales, but also a time when website traffic and transaction volumes increase significantly. E-commerce websites, membership systems, and transaction platforms consequently face greater cybersecurity risks. Businesses should proactively identify and address potential vulnerabilities through website and server vulnerability scanning and penetration testing. Social engineering simulations can also help reduce the risk of employees accidentally clicking malicious links or disclosing sensitive information. By strengthening technical defenses, employee awareness, and security management practices, businesses can enhance their overall cybersecurity posture and better prepare for stable operations during the Q4 shopping season.
