Detect Ransomware Attacks with ExtraHop

SECURITY USE CASE

Ransomware: Is Your Network Compromised?

How many ransomware threats are hiding on your network right now? It’s just one of many questions you should be asking now that threat actors have started switching up their tactics. With ExtraHop, every time attackers take a step in your network, you have an opportunity to regain the advantage—and catch them before the payload is activated.

Challenges

Attackers Don't Break In, They Log In

Credential compromise is now the dominant attack vector, with 81% of breaches involving compromised identities (Verizon DBIR Report). With a rise in SSO Federation, the increase in token theft, and prevalence of non-human identities, security teams need real-time identity insights to spot and investigate suspicious user behavior.

The conventional approach for ransomware mitigation focuses on the prevention of initial access and relies on backup recovery. Prevention alone is inefficient against ransomware: Attackers only need to succeed once, while you have to be right against them 100% of the time. And, restoring data doesn’t negate the downtime, the loss of business, reputation, and any legal consequences of a data breach.

Opportunities

Network Data Is the Best Weapon Against Ransomware

ExtraHop reveals and stops ransomware campaigns coordinated by top threat actors, including Qilin, LockBit, and RansomHub, as they attempt to move laterally through your infrastructure, flipping the odds in your favor. Once inside your network, attackers have to constantly evade detection, but RevealX seeks them out and stops them. It spots unusual user activity and suspicious behaviors before data is encrypted. Guided investigative workflows help pinpoint impacted devices, and forensic visibility gets you to the root cause faster, ultimately reducing your mean time to remediation (MTTR).

What controls do you have in place for EDR gaps and evasion?

Ransomware attackers disable or evade EDR-enabled endpoints by applying living-off-the-land techniques and others. RevealX provides real-time visibility and detection of lateral movement within your networks to eliminate EDR blind spots.

How would you identify a ransomware campaign already inside your perimeter?

Network data gives you a superior understanding of normal behavior and quickly detects deviations. RevealX spots ransomware signals and attacker behaviors that other methods miss, dynamically adjusting cloud-scale ML to your changing environment.

How would you ensure that intruders are fully eliminated to prevent recurrence?

With up to 365 days of continuous traffic record lookback, automated retrospective detection, and petabyte-scale long-term packet repositories, RevealX provides the forensic-level data you need to investigate and eradicate "intruder residue" and prevent attack recurrence.

Ransomware Is Noisy, Learn to Listen

Ransomware attacks have evolved, and once inside, adversaries are moving laterally to accumulate valuable and sensitive data to ensure that organizations will pay a higher ransom. Intruders are now spending more time in your network, creating noise and causing them to risk detection. With RevealX, every time attackers take a step, you have an opportunity to regain the advantage—and stop them before they do more damage.
