Stop ransomware where it actually hurts: data exfiltration.

Modern ransomware goes further than encryption. It steals first, then extorts. This is BlackFog’s hub on how double extortion really works, and how our anti data exfiltration (ADX) technology stops data leaving the device in real-time.

the shift

Encryption is no longer the point. The data is.

Backups changed the ransomware equation. So attackers changed the game: they exfiltrate sensitive data first, then encrypt, then threaten to publish. Restoring from backup no longer makes the threat go away, because the data is already gone.

Defenses built to detect malware or recover files don’t address the exfiltration problem. The only way to neutralize double extortion is to stop the data from leaving in the first place, at the source, on the endpoint.

the anatomy

Where a double-extortion attack breaks, and where ADX breaks it.

01

Initial access

Phishing, stolen credentials, or an unpatched vulnerability gives an attacker access to the endpoint.

Data exfiltration

Sensitive data is transferred to attacker infrastructure. ADX stops the outbound transfer on the device, in real-time.

03

Encryption

Files are locked. Backups can restore them, which is why attackers increasingly use data theft as additional leverage.

04

Extortion

Pay or the stolen data is leaked or sold. Stop the exfiltration, and you remove the stolen data attackers use as leverage.

Backups can recover encrypted files. They can’t recover stolen data. Stop stage 02, and you remove the leverage behind double extortion.

HOW ADX STOPS IT

One control point,
the whole attack lifecycle.

behavioral

No signatures to wait for

ADX analyzes activity by behavior, so novel, fileless and zero-day ransomware is caught without a prior signature.

AT THE SOURCE

Exfiltration blocked on-device

Outbound transfers to C2 and staging destinations are stopped on the endpoint, before a byte leaves.

EVERYWHERE

On or off the network

Protection travels with the device, with no dependency on the corporate network or a cloud proxy.

ADX Protect delivers this

The product that puts real-time anti data exfiltration prevention on every endpoint.
