Phishing Campaign

 

What is a Phishing Campaign?

A phishing campaign is a type of scam designed to trick its victims into disclosing sensitive information.

The goal is often to trick victims into sharing their login credentials, credit card details, or other personal data.

While each campaign will be unique, almost all phishing attacks share the following characteristics:

  • Urgency: Phishing messages create a sense of urgency to trick victims into taking quick action. By creating a sense of urgency victims often don’t completely think through their actions.

  • Spoofed Sender: Attackers spoof the sender’s email address to make the email appear as if it’s coming from a known and trusted entity.

  • Malicious Links or Attachments: These emails often include links to fraudulent websites or attachments that contain malware.

  • Personalization: Some phishing emails include personal details about the target. This makes them more convincing (a tactic known as spear phishing).

  • Fake Login Pages: Victims are redirected to a webpage designed to look like a legitimate site. They are then tricking into entering their credentials.

How Do Phishing Campaigns Work?

While there are a number of ways to execute a phishing attack, here’s how they typically work:

  1. Crafting the Bait: Attackers create a convincing email, message, and / or website that appears to come from a legitimate source. These often include banks, online retailers, or well-known organizations. The messages often contain urgent or enticing content to prompt quick action.
  2. Distribution: The phishing messages are sent to a large number of potential victims through email, social media, text messages, or other communication platforms.
  3. Luring the Victims: The messages typically contain links or attachments that lead to fake websites designed to steal information. These websites look identical to legitimate sites to trick users into entering their credentials or downloading malware.
  4. Harvesting Information: Once the victims enter their information on the fake site or download the malicious attachment, the attackers capture this data. This information is then used to access the victims’ accounts, steal money, or commit identity fraud.
  5. Exploitation: The stolen data is used for financial gain, either by directly exploiting the information or selling it on the dark web to other criminals. The attackers might also use the information to launch follow-up attacks, such as account takeovers or additional phishing attempts.

What are the Different Types of Phishing Campaigns?

Phishing campaigns come in various forms. Each tailored to exploit a different kind of target. Below are the eight common types of phishing attacks used in the wild:

  1. Email Phishing: This is the most common type, where attackers send emails that appear to be from a reputable source. These emails often contain malicious links or attachments. The goal is to steal as many login credentials or infect as many devices with malware as possible.
  2. Spear Phishing: A more targeted form of phishing, spear phishing involves personalized messages aimed at specific individuals or organizations. Attackers research their target beforehand to make the emails more convincing.
  3. Whaling: Similar to spear phishing, whaling targets high-profile individuals such as executives or important decision-makers within an organization. The goal is often to gain access to sensitive information or authorize large financial transactions.
  4. Smishing (SMS Phishing): Attackers use text messages to trick victims into clicking on malicious links or providing personal information. These messages often appear to come from legitimate sources like banks or service providers.
  5. Vishing (Voice Phishing): This involves voice calls where attackers pretend to be a trusted entities. They often spoof their caller ID to look legitimate. In order to extract sensitive information, they often create a sense of urgency to prompt the victim into acting without thinking clearly.
  6. Pharming: This technique redirects users from legitimate websites to fraudulent ones without their knowledge. It usually involves DNS (Domain Name System) poisoning. This is where attackers change the IP address associated with a domain to redirect traffic.
  7. Business Email Compromise (BEC): BEC attacks target businesses and attempt to exploit their processes. Attackers impersonate company executives or vendors to trick employees into transferring funds or sharing sensitive information.
  8. Angler Phishing: This method involves attackers pretending to be customer service representatives on social media platforms. They respond to customer questions or complaints with malicious links or requests for personal information.

Examples of Phishing Campaigns

Here are some notable real-world examples of phishing attacks:

  • Google and Facebook Phishing Attack: Between 2013 and 2015, Evaldas Rimasauskas tricked employees at Google and Facebook into making payments by sending fake invoices and posing as a vendor. This scheme led to the theft of over $100 million. The sophistication of the emails made them look legitimate, which tricked employees into transferring large sums of money to the attacker’s accounts.
  • Target Data Breach: The breach began in 2013 when a third-party vendor, Fazio Mechanical, was compromised through a phishing email. Attackers installed malware that stole login credentials, which they used to infiltrate Target’s network. This led to the theft of millions of customer records, including credit and debit card information.
  • Ubiquiti Networks Inc.: In 2015, Ubiquiti Networks lost $46.7 million due to a spear phishing attack that involved fake emails from an outside entity targeting the company’s finance department. The attackers used spoofed email addresses to trick employees into transferring funds to overseas accounts.

How to Prevent Phishing Attacks

Here are some strategies that when combined help prevent phishing attacks:

  • Suspicious Links and Attachments: Teach employees to hover over links to check their true destination before clicking. Be extremely careful with file attachments with extensions like .exe, .bat, .vbs, .js, or .scr.

  • Verify Requests: Encourage employees to verify any unusual requests for sensitive information. This is doubly true for those that seem urgent. Always contact the requester through a different communication channel.

  • Phishing Simulations: Run simulated phishing attacks to test employees’ awareness and improve their ability to spot phishing attempts.

  • Reporting Mechanisms: Establish a easy-to-use protocol for employees to report suspected phishing emails to the IT department.

  • Spam Filters: Use spam filters to block phishing emails from reaching users’ inboxes.

  • Email Authentication: Implement email authentication protocols like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance) to verify the legitimacy of incoming emails.

  • MFA Implementation: Require multi-factor authentication for accessing sensitive systems and data. This adds an extra layer of security beyond just a password.

  • Anti-Phishing Toolbars: Use anti-phishing toolbars in web browsers that can check visited sites against a list of known phishing websites.

  • Patching: Ensure that all software, including operating systems and applications, are regularly updated. This will patch known vulnerabilities that could be exploited by phishing attacks.

  • Preparedness: Develop and maintain an incident response plan. Having a plan in place before an incident, helps you stay effective when an attack happens.

  • Strong Password Policies: Enforce the use of a password manager. This ensures that employees use a unique password for every account.

  • Antivirus and Anti-Malware: Install and regularly update antivirus and anti-malware software to detect and prevent phishing-related malware.

  • Continuous Monitoring: Leverage data breach monitoring services to detect compromised credentials early. This helps prevent account takeovers that could lead to impersonation and MiTM attacks.
