A serious vulnerability has been found in the Apache Log4j software. This software is used in many web applications and systems, by many organizations and companies. The extent and impact of this vulnerability is not known yet. However, we take this seriously. We are currently examining systems to detect on the basis of indicators of comprise (IOCs) whether this vulnerability has been exploited before.

Therefore Ordina has proactively investigated its customers IT environment as part of Ordina’s (contractual) obligations, as well as Ordina’s own environment. When we identify a vulnerability, we mitigate the risk by installing the Apache Log4j patch or by turning off the software and/or disconnect your internet connection.

This gives us better insight into the damage and prevents further damage to the network and systems.
