Phishing Prevention

Phishing Prevention – Best Ways to Protect Your Business

What Is Phishing?

Phishing is a sort of cybersecurity attack in which a hacker sends an email containing a link or document that appears to be authentic but is intended to obtain personal information. A phishing email appears to be from a reputable source (e.g., your bank, another employee, a well-known company). When someone clicks on the malicious link or attachment, he or she will be asked to submit personal information. The link could also infect the employee’s computer with malware. Employees may unknowingly provide hackers with exactly what they need to get access to critical enterprise accounts.

Phishing can take several forms, ranging from generic to highly tailored. To respond appropriately to a phishing assault, you must first understand the differences. The four basic forms of phishing attempts are shown here, along with a brief description of each attack’s objectives.

  • Phishing is a generic attempt to obtain sensitive information by deceiving consumers via email.
  • Vishing is the practice of making cold calls to an entity in order to persuade the recipient to take some action.
  • Spear Phishing is a type of targeted phishing attack that targets specific persons or groups inside an organization and personalizes the message to build credibility.
  • Whaling is an extremely targeted attempt to obtain sensitive information from high-value employees within a company utilizing email as the communication medium.

Phishing Prevention Basics

Phishing prevention refers to a set of tools and procedures that can be used to detect and neutralize phishing attempts before they happen. This includes extensive user education to raise phishing awareness, the implementation of specialized anti-phishing solutions, tools, and programs, and the implementation of a variety of other phishing security measures aimed at proactive phishing protection as well as mitigation techniques for attacks that do manage to breach security.

Sure, all kinds of clever technologies may be implemented in the hopes of thwarting phishing attempts. The most effective plan, on the other hand, would be to develop a tailored strategy based on the specific business circumstances.

To Catch a Phisher, First You Have to Think Like a Phisher

Taking a high-level view, it’s important to analyze how a threat actor might gain an initial foothold on a company’s infrastructure before shifting aggressively to steal crucial data. The following method explains some phases that can demonstrate how the process works when considering this initial foothold. 

  • Research the Company: The fictional company’s organizational structure, business drivers, vendors, employee social media posts, and other information repositories must be researched first.
  • Obtain a List of Emails: Now that you have the corporate information and some decent phishing techniques, it’s time to harvest publicly available emails, as well as “mangling” known employee names.
  • Decide Where the Email Should Come From: After gathering information on the company, internal individuals, and a list of emails, the next step is to choose where the email should come from. This may entail obtaining a domain name that is similar to the phony company’s or another company with which the company is affiliated.
  • Getting a Domain to Work for You: When phishers want their communication to appear as if it came from someone at a specific firm, they commonly manipulate a domain. Mangling a domain can be done with a variety of tools and involves compiling a list of known ways to mistype a domain while maintaining its resemblance to the original.
  • Plan What You Want Your Phishing Targets to Do: A typical method is to clone a well-known website that closely mimics the fake organization’s login interface, or to create a document containing malware that someone inside the company would likely open.

Implement Basic Phishing Prevention Methods

Set Up SPF, DKIM, and DMARC – the Anti-Spam Protocol Trifecta

Make sure you’ve done some fundamental steps to limit the danger of phishing before using an anti-phishing solution. SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) are free and easy to implement standard protocols for authenticating email and combating spam and email spoofing. These protocols will not eliminate the threat of phishing, but they will make the opposition’s life more difficult.

Set Up Multi-Factor Authentication

Many credential-based attacks can be avoided by requiring multi-factor authentication (MFA). If a phishing assault succeeds in obtaining credentials, requiring extra authentication means the attack will most likely end there.

Use Your Email Platform’s Built-In Phishing Features

Phishing prevention is aided by built-in rules and policies in cloud email platforms such as Microsoft 365 and Google G Suite. To detect malicious intent, they compare your messages to the billions of others they receive every day. On-premises email servers, such as Microsoft Exchange, have anti-malware features.
