…well, to make things work, honestly. Not for fun nor profit.

TL;DR: Intel’s ixgbe-driver sees our Finisar 10Gb SPF+ cards as 1Gb, and therefor loading these drivers will fail. But this patch by Crypt0jan will make them work and spare you his headaches, anger and frustration. You’re welcome.

TL;DR: secure your infrastructure. Open Redis servers are being abused by cybercriminals to store shell commands in your memory. Also, the underlying problem is not new.

1 — open mind

Chapter8 gathers cyber intelligence through several sources, some of which scan the internet for openly accessible services. You’d be surprised — unpleasantly I hope — by the amount of accessible and unsecured services on the net.

In this story, I’ll discuss the misuse of unsecured Redis servers in the Netherlands. Redis is “an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker.” …

Een digitale aanval is een smerig straatgevecht. Geen keurige wedstrijd met lijntjes op een veld, een scheidsrechter en een paar gekleurde kaarten. Op een dergelijk gevecht kun je je nooit volledig voorbereiden, maar intensieve training zal je helpen om ook in een straatgevecht beter te kunnen anticiperen.
