Cybercriminals continue to adapt their attack techniques in the digital space. Most people have heard of phishing attacks, however, spear phishing is a targeted attack vector that is far worse. If an organization wants to protect confidential information and reputations, it is important to understand this technique through the use of cyberthreat intelligence.
Spear phishing is a planned cyber attack in which an attacker sends an email to a specific person within a targeted organization. The big difference between spear phishing and email phishing is that spear phishing is directed, researched and tailored to specifically deceive an individual. Spear phishing attacks utilize the data gathered from a person's social media, the company website or any other publicly available content to create believable messages and appear legitimate.
The deception within spear phish is the level of personalization that the attacker can provide. The attacker might reference a company event that has taken place, name colleagues in the email or replicate the tone from previous communications in order to enhance trust and believability. The level of customization from spear phishing makes it far more effective than traditional phishing attacks, as they have a success rate of significantly greater than 50%.
Cyber threat intelligence is essential in gaining an understanding of and confronting spear phishing attacks. It consists of the approaches that organizations take to collect information on potential threats and analyze and interpret that data to identify attack patterns and vulnerabilities before they are exploited. When conducting cyber threat intelligence, organizations take an intelligence-driven approach that allows security teams to predict an attacker’s actions and implement defenses to protect against the attack. The usage of cyber threat intelligence includes monitoring the threat actor's tactics, techniques, and procedures (TTPs) as well as analyzing the indicators of compromise that may occur in addition to developing and sharing intelligence regarding potential threats in some cases, or as a minimum tracking the emerging potential threats across the industry and develop collective defensive mechanisms. This is a proactive stance as opposed to the more frequently occurring, reactive security measures that take place after an attack has already occurred.
Spear-phishing scams typically have a few very different characteristics than traditional phishing:
Personalization and Research: Attackers invest a substantial amount of time researching their targets, gathering information about job duties, relationships, and current work. This research phase is where cyber threat intelligence is especially useful in detecting reconnaissance activity.
Trusted Sender Impersonation: Spear phishing emails nearly always appear to come from trusted senders, often impersonating executives, colleagues, or business partners, in many cases, the attacker compromises authentic email accounts, or they create well-crafted spoofed sender addresses.
Urgency and Social Engineering: Frequently, spear phishing emails create a sense of urgency where recipients need to act quickly and often don't take time to verify the request. Common situations include wire transfers, password resets, request for confidential documents.
Professional Quality: The spear phishing emails are typically well-written, and contain accurate information about the target or organization, compared to traditional phishing emails which are full of obvious grammatical errors.
To prevent against spear phishing, organizations need to rely on a multi-prong approach utilizing technology, processes, and personnel. Managed Cyber Security Services can offer total protection by leveraging advanced email filtering, threat detection systems, and ongoing analysis and monitoring. Security awareness training is the best defensive strategy that educates employees on spear phishing techniques. Ongoing training sessions prepare staff to identify suspicious emails, verify sender identity, and promptly notify authorities of all potential threats. Simulation and anti-phishing programs help organizations measure employee response to realistic spear phishing emails. These controlled exercises highlight vulnerability as it relates to human factors involved and promote learning through doing. Of course, advanced technical controls matter. Network security solutions can help identify anomalous email behavior, can verify sender authenticity through DMARC and SPF protocols, and can prevent users from accessing malicious messages by quarantining them first.
With the growth of artificial intelligence (AI) and machine learning, both adversaries and defenders are using AI technologies. Cybercriminals can be seen utilizing AI technologies to enhance their spear phishing campaigns and make them even more believable, while security teams are using AI-powered cyber threat intelligence platforms to detect threats and respond to them quickly. Organizations should stay in front of the threat by engaging knowledgeable Cybersecurity Consulting Services that understand the threats and vulnerabilities. The cybersecurity experts help design holistic and comprehensive social engineering defense strategies that include addressing human vulnerabilities and technical weaknesses.
Spear phishing continues to be one of the most successful means of cyberattacks, though it is not impossible to manage effectively. Organizations can greatly reduce their risk by utilizing cyber-threat intelligence, implementing strong security controls, and creating a security conscious culture. The primary objective is to take a proactive, intelligence-based stance to anticipate rather than simply respond to threats.
It is worth reiterating that cybersecurity is not solely a technology problem—it's a people problem. By investing in a comprehensive suite of cyber security services that combines threat intelligence and user education, organizations can create a powerful defense against spear phishing.
