At the end of May, we discovered a campaign spreading Remote Access Trojan (RAT) malware—programs that allow attackers to remotely control the infected system. The group we analyzed distinguished itself by not targeting a specific family of RATs for infection. Several trojans (all widely available) were observed in the attacks within the campaign. This characteristic of the group reminded us of the rat king—a mythical creature composed of […]
VictoriaMetrics, TimescaleDB, and InfluxDB were compared in the previous article using a dataset of one billion data points belonging to 40K unique time series.

Thus, metrics from thousands of servers can fit […]

When it came time for deployment, I found a couple of good tutorials on how to do this on a full server with all its intricacies. I'm not very strong in deployment; I'm generally more of a front-end person than […]
