Type: domain | Verdict: SUSPICIOUS (60% confidence, MEDIUM strength)

  • OmniSense_KB: promoted with score 60 and confidence 0.6
  • Prior Enrichment Signal: seen 2 times prior

Consolidated Assessment

The domain example.com was analyzed and found to be associated with the Microsoft Phishing Collection according to OTXQuery. Additionally, it has a promoted score of 60 with confidence 0.6 from OmniSense_KB. The domain has been seen 2 times prior, indicating a repeat-offender signal. While there is no direct evidence of malicious hosting or C2 activity, the domain's association with phishing and its repeated appearance suggest a suspicious threat class, potentially related to credential compromise or malware delivery. The analyst should investigate further to confirm if the domain is being used for phishing activities, possibly targeting Microsoft-related services, and assess the risk to the organization's users.

ReferenceWhat is IOC reputation?

An Indicator of Compromise (IOC) — an IP, domain, URL, or file hash — is a forensic artifact suggesting an intrusion. "Reputation" is the consensus across threat-intel feeds: is this IOC associated with known malicious activity, and how confident is each source? A single source rarely tells the full story; SARA aggregates eight independent feeds and weights the verdict accordingly.

GuideHow to use this tool

  1. Paste any IOC into the search box — IPv4 / domain / URL / SHA-256 / SHA-1 / MD5. Defanged forms (hxxp://, [.]) are auto-refanged.
  2. SARA detects the IOC type and runs it through up to eight threat-intel sources in parallel.
  3. Read the verdict + the analyst summary. Pivot into SARA chat with the "Pivot in SARA" chip for a hunt plan.

When to useWhen is IOC reputation the right signal?

Triaging a SOC alert

A SIEM alert references an IP / domain / hash you've never seen. 30 seconds here tells you whether it's a known-bad worth escalating or a noisy false positive.

Phishing email hunt

Quickly check the sender IP + every URL extracted from a suspicious email. Cross-reference with the Phishing Analyzer for the full mail-flow story.

Threat-hunt pivoting

Take an IOC you've confirmed bad in one investigation and check whether it touches anything else in your environment.

Bulk enrichment via API

Pipe alert IOCs through the API on every detection. The free page is the same engine, exposed for ad-hoc checks.
