In the data-driven business world, the use of email has reached such a level that it has now become a top cyberattack vector. Cybercriminals persistently target high-value individuals who handle sensitive data within an organization through phishing emails. Though some claim that phishing is ineffective, hackers are leveraging advanced technologies and sophisticated methods like polymorphic phishing attacks to extract information. In this article at Security Boulevard, Ahona Rudra explains why it is necessary to take adequate precautions to prevent polymorphic phishing attacks.
An Example of Polymorphism
Hackers send an email with a PDF file attached. When you fail to identify the email as phishing and open the file, it prompts an update message claiming the tool isn’t updated. When you click on the link to update the tool, it redirects you to a cloned web page that asks you to enter your credentials. “Ill-informed and unaware employees can easily fall for such polymorphic phishing attacks and give up their company login credentials on the spoofed page,” says Ahona.
Further, the email spreads like a virus across the company, with every employee receiving an email with a slight yet significant change. The change in the characteristics of each phishing email helps the hackers in evading automatic anti-phishing measures. According to the studies conducted by the Israel-based cybersecurity firm IRONSCALES, 42% of the phishing attempts were polymorphic.
Targeted phishing attacks are increasingly bypassing gateway security controls and landing right into employees’ mailboxes worldwide.
How to Prevent Such Attacks?
The best way to mitigate such attacks is to improve your current cybersecurity posture by installing robust IT infrastructure that can detect the attacks in time and thwart them with greater potency. Besides, also conduct phishing attack awareness programs to help employees gain better insights on social engineering attack vectors. Proper awareness among the end-users will reduce the chances of polymorphic phishing attacks.
