What is spear phishing?
Spear phishing is the practice of sending fraudulent emails that targets specific individual(s) or organization for the purpose of gaining unauthorized access to confidential information.
Spear phishing emails contain a wealth of hidden evidence that can be used to track and understand the methods used by attackers to target the organization. By extracting that information, analysts can better understand what to look for to identify other users that may have succumbed to the trick.
Armed with this evidence, analysts can discover associations between multiple spear phishing messages to understand a wider campaign that can be underway. Identifying malware samples across campaigns, and associating them with adversary profiles (and therefore intentions) notably improves the ability to respond.
Conducting this level of analysis can be difficult and laborious. Typically, analysts must discover these associations by manually sifting through messages and correlating the information they discover about the campaign with external data on adversaries and their methods.

Our approach to spear phishing
ThreatQ simplifies the process of parsing and analyzing spear phish emails for prevention and response. With a centralized Threat Library that aggregates all the external threat data organizations subscribe to along with internal threat and event data for context and relevance, analysts are in a position to begin to analyze and determine which emails to focus on.
Recipients of suspicious emails forward the email to an inbox that ThreatQ monitors continuously. Comparing indicators from the email against the data in the Threat Library, ThreatQ determines high risk emails versus low risk, allowing prioritization and noise reduction.
On high-priority items, ThreatQ automatically performs rear-view mirror searches on email logs using SMTP-specific IOCs – email subject, email sender, email filename/attachments. Analysts are able to identify spear phish attacks that might have fallen through the cracks because they were not identified as malicious at the time.
Going a step further, analysts can query to identify all the spear phish recipients and then overlap those findings with vulnerability scan results to determine the scope and help accelerate response and containment.
- Triage spear phish faster and more effectively based on analyst familiarity of adversary TTPs.
- Improved spear phishing attribution.
- Increased understanding of the environment and susceptibility to spear phish attacks.
- Proactive protection against spear phishing attacks.
