Silent Push reveals adversary infrastructure, campaigns, and security problems by searching across the most timely, accurate and complete Threat Intelligence dataset available. Defenders can focus on stopping threats before they cause a problem and significantly improve their security operations across the entire attack chain whilst simultaneously reducing operational complexity. The Silent Push platform exposes Indicators of Future Attack (IOFA) by applying unique behavioral fingerprints to attacker activity and searching our dataset. Security teams can identify new impending attacks, rather than relying upon out-of-date IOCs delivered by legacy threat intelligence. Organizations are better protected by understanding emerging developing threats before launch, proactively solving problems within infrastructure, and gaining timely and tailored threat intelligence with IoFA, that allows organizations to stay one step ahead of advanced attackers.

Identify similar phishing domains that could be leveraged by attackers against your organization. Investigate the potential issues users may face when attempting to type your domain name accurately. Look for fraudulent domains that adversaries might exploit for malicious purposes, as this can help in identifying typosquatters, phishing schemes, scams, and instances of brand impersonation. This information serves as a valuable resource for enhanced targeted threat intelligence. The process of DNS fuzzing automates the detection of potentially harmful domains aimed at your organization by creating a vast array of variations from a specified domain name and checking if any of these variations are active. Furthermore, it can produce fuzzy hashes of web pages to identify ongoing phishing attempts, instances of brand impersonation, and additional threats, thereby providing a more comprehensive security measure. By utilizing this tool, organizations can significantly bolster their defenses against evolving cyber threats.
