In the digital age, phishing, and social engineering attacks have become increasingly common and complex, which poses significant threats. These cyberattacks exploit human psychology to gain unauthorized access to sensitive information. In this article, we explore the evolving techniques used in phishing and social engineering, the recent examples of such attacks in large-size organizations, and provide practical protection measures.
Spear phishing targets specific individuals or organizations, using personalized information to make the attack appear legitimate. This technique often involves extensive research on the target audience to entice them with convincing messages.
A form of spear phishing called "whaling" targets high-profile individuals, such as executives or government officials. The goal is to trick them into divulging sensitive information or transferring funds.
Vishing (voice phishing) and smishing (SMS phishing) involve using phone calls or text messages to deceive targets. These methods are particularly effective because they exploit the trust users place in phone communications.
BEC attacks involve impersonating business executives or employees to manipulate recipients into making unauthorized transactions or revealing confidential information. These attacks often exploit email systems and social engineering tactics.
In May 2021, Colonial Pipeline fell victim to a ransomware attack due to a leaked password and a lack of multifactor authentication. The attackers gained access to the company's network, disrupting fuel supplies across the Eastern United States and causing widespread panic and fuel shortages. The pipeline's operations were stopped for several days, resulting in a significant economic impact. This incident highlights the susceptibility of critical infrastructure to social engineering attacks.
In September 2020, Levitating Capital was targeted by a phishing attack. First, cybercriminals sent a fake Zoom invitation to executive Mike Fagan, gaining access to his computer. On September 15, a fraudulent "capital call" request was sent to administrator AET. While at the gym, Mr. Fagan responded via email to a call from AET, and hackers intercepted the email chain to authorize payments. The next day, $1.2 million was sent to a Unique Star Trading account at ANZ, Bankstown Shopping Centre. Between September 16 and 26, nearly $800,000 was cleared from the account in 66 transactions. This incident underscored the need for verifying high-stakes communications and highlighted vulnerabilities in financial institutions.
Spectrum Health, a major healthcare provider, faced a smishing attack in 2022, where patients received text messages claimed to be appointment reminders that included malicious links. Clicking on these links compromised patients' personal information.
In addition, Spectrum Health patients were targeted in a vishing campaign in 2020. Hackers called patients pretending to be Spectrum employees, using "spoofed" caller IDs to appear legitimate, and pressured them to provide member numbers or protected health information. These attacks typically begin with email communication and continue via phone calls, demonstrating the evolving threat landscape in healthcare cybersecurity.
Educating employees about the risks of phishing and social engineering is crucial. Regular training sessions can help employees recognize suspicious emails, phone calls, and messages, which reduces the likelihood of successful attacks.
Implementing MFA adds an extra layer of security by requiring users to provide multiple forms of verification before accessing sensitive information. This measure can significantly reduce the effectiveness of phishing attacks.
Advanced email filtering solutions can help detect and block phishing emails before they reach employees' inboxes. Additionally, implementing security protocols like SPF, DKIM, and DMARC can help prevent email spoofing.
Establishing verification procedures for high-stakes transactions or sensitive information requests can prevent unauthorized actions. For example, requiring verbal confirmation for fund transfers can stop whaling attacks.
Having a robust incident response plan in place ensures that organizations can quickly and effectively respond to phishing and social engineering attacks. Regularly testing and updating the plan can improve preparedness and minimize damage.
