The Consequencies

Financial Losses

Since the main goal of the attack was to hijack a payment the company obviosuly had a very big direct financial loss. We can't forget, however, that reputational damage can also easily produce economic damage, and this is clearly the case.

Privacy Violations

Having gained access to all the company systems, the attacker had also got access to loads personal data of providers and clients. This is clearly a problem as many contracts are NDA-protected.

Further Risks

Even if the main attack ended, the insight gathered by the attacker expose the company to the risk of others similar attacks in the future. And since insights remains to the attacker, a password change is not enough to mitigate this risk.

ZADIG Smart
provides at least three solutions to stop this attacks

OFF-SITE WORKING IS CLEARLY RISKIER THAN ON-SITE WORKING,
however there are few precautions that could have stopped this attack, like applying full disk encryption to the device, or handling permissions safely.
ZADIG Smart can give you at least three complete solutions to stop this attack.

Do you wish to prevent and eliminate these threats?

Mobile Device Management

A well configured MDM could have enforced full disk encryption and remotely locked the device immediately after the thief, thus preventing the attack from taking place. In addition, it will have also helped to easily reconfigure the device after the restitution, allowing the IT to just wipe it and get rid of the spyware

SSO

Instead of having a single credential for everyone, the SSO allow you to configure (in the service you are accessing) the same login you are already using for ZADIG Smart. This way, should a credential be compromised, it can easily be revoked for every service without impacting other users' workflow.

Compliant-Only Access

To further enhance your security, we support the option to restrict access to our login only to compliant devices. This means that a session reuse on another non-enrolled device would have been impossible, thus preventing the attacker to gain access to corporate resources
