In February, we saw about a 10% decrease in the number of unique attackers, but they were more active. Usually, we see attackers come and go, but in February, although it was fewer attackers in total, we had on average, more attackers blocked every day. This means that those attackers stayed active longer than in January.

Sentinel View report – January 2023
In January, we encountered slightly more attackers than in December. But overall, behavior stays the same. The number of attackers per device and victims per attacker didn’t change much. Looking back at our first report, we also had about the same amount of victims per attacker but more attackers per device. The trend for the last three months is to target about 20 Turris devices on average if you are an attacker.

BIRD Journey to Threads. Chapter 4: Memory and other resource management.
BIRD is mostly a large specialized database engine, storing mega/gigabytes of Internet routing data in memory.

The resource system has not changed much between v2 and v3, yet it deserves a short chapter.
Sentinel View v1.2.0: Better Check Your Passwords Tonight
With all the data we collect (as you can read in details in my previous article) the challenge is not to figure out what to do with the data, but the implementation of the idea itself. When we have access to so many passwords, it was only a matter of time to implement some kind of search for passwords that show up in incident records. And this one wasn’t so complex either. We bring to you today a Password Checker with brand new release v1.2.0 of Sentinel View.

uCollect is dead, long live Turris Sentinel!
If you follow what we do, you might have noticed that we recently announced the end of Turris OS 3.X. It was first released in 2016 and it was with us for quite some time. But in the end we managed to debug the migration to Turris OS 5.x and migrated everybody over. But this blog post is not about that. This post is about deprecation one of the parts, that was replaced by a newer and better system – uCollect.
STOPonline.cz in 2021
If we try to compare the past two years, we can say that in terms of the number of processed incoming reports, the STOPonline.cz line was much more successful, if we can call it that.
