Trellix CEO, Bryan Palma, explains the critical need for security that’s always learning.
As per Gartner, "XDR is an emerging technology that can offer improved threat prevention, detection and response."
Trellix announced the establishment of the Trellix Advanced Research Center to advance global threat intelligence.
Trellix Advanced Research Center analyzes Q4 2022 threat data on ransomware, nation-states, sectors, vectors, LotL, MITRE ATT&CK techniques, and emails.
What Is a Zero-Day Exploit?
A zero-day vulnerability, at its core, is a flaw. It is an unknown exploit in the wild that exposes a vulnerability in software or hardware and can create complicated problems well before anyone realizes something is wrong. In fact, a zero-day exploit leaves NO opportunity for detection ... at first.
Vulnerability timeline
A zero-day attack happens once that flaw, or software/hardware vulnerability, is exploited and attackers release malware before a developer has an opportunity to create a patch to fix the vulnerability—hence “zero-day.” Let’s break down the steps of the window of vulnerability:
- A company’s developers create software, but unbeknownst to them it contains a vulnerability.
- The threat actor spots that vulnerability either before the developer does or acts on it before the developer has a chance to fix it.
- The attacker writes and implements exploit code while the vulnerability is still open and available
- After releasing the exploit, either the public recognizes it in the form of identity or information theft, or the developer catches it and creates a patch to staunch the cyber-bleeding.
Once a patch is written and used, the exploit is no longer called a zero-day exploit. These attacks are rarely discovered right away. In fact, it often takes not just days but months and sometimes years before a developer learns of the vulnerability that led to an attack.
