THE ISSUES OF COMPUTER
SECURITY

WHO CAN ASSERT NOT TO OWN ANY CONNECTED DEVICE NOWADAYS? COMPUTERS, SMARTPHONES, TABLETS, TELEVISIONS, DOMOTICS ... WE LIVE IN AN ULTRA-CONNECTED WORLD AND THIS IS NOT LIKELY TO CHANGE ANYTIME SOON.

Information has become the most valuable asset in the social, political and industrial contexts. Therefore, the protection of information assets often turns out to be crucial when it comes to ensuring the sustainability of industrial or state organizations - although at first glance it may appear to represent additional costs with no return on investment.

The press increasingly spreads the word about the disclosure of users' personal data, ransom demands via ransomware and compromises of large companies. The resources deployed to safeguard data are increasing at the same pace as those engaged to breach through the security barriers.

Case study

Most frequent cases

Spear-phishing

Our team sends a malicious email to a dozen user. Two users enable the macro, which allows us to take over the workstations. The team then pivots towards the internal network, escalates privileges and exfiltrates the mission trophies.
Spear-phishing

Vulnerable front-end server compromise

Our team identifies a critical vulnerability in an application exposed on the Internet, compromises a server, then another, and gradually accesses the internal network to demonstrate to the mission's sponsor that it is possible to access the defined trophies.
Vulnerable front-end server compromise

Reuse of authentication secrets

The team finds the passwords of several employees in public data breaches. Some passwords are still valid on an extranet which does not require two-factor authentication. A vulnerability on this extranet leads to the compromise of the internal domain and to the retrieval of sensitive data.
