OTX Bot<p>Threat Actors Exploit Linux SSH Servers with SVF Botnet</p><p>Cybersecurity researchers have uncovered a new attack campaign in which threat<br>actors are targeting Linux SSH servers with weak credentials to deploy the, SVF<br>botnet a Python based DDoS malware. This botnet uses Discord as its command-<br>and-control (C2) platform allowing attackers to manage infected servers in real<br>time. The SVF botnet is capable of launching Layer 7 (HTTP flood) and Layer 4<br>(UDP flood) DDoS attacks turning compromised servers into powerful tools for<br>disrupting targeted systems.</p><p>Pulse ID: 6880a810b601758421acd5a4<br>Pulse Link: <a href="https://otx.alienvault.com/pulse/6880a810b601758421acd5a4" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">otx.alienvault.com/pulse/6880a</span><span class="invisible">810b601758421acd5a4</span></a> <br>Pulse Author: cryptocti<br>Created: 2025-07-23 09:14:56</p><p>Be advised, this data is unverified and should be considered preliminary.

Nicd<p><span>I started hosting a </span><a href="https://social.ahlcode.fi/tags/Valheim" rel="nofollow noopener" target="_blank">#Valheim</a><span> dedicated server for my friends, but I didn't want it to be constantly running. I reached for </span><a href="https://social.ahlcode.fi/tags/systemd" rel="nofollow noopener" target="_blank">#systemd</a><span> socket activation, where systemd will start and stop the server on demand. Unfortunately Valheim doesn't support it by itself and systemd's proxy doesn't support UDP.<br><br>So I wrote a small UDP </span><a href="https://social.ahlcode.fi/tags/NodeJS" rel="nofollow noopener" target="_blank">#NodeJS</a><span> proxy to do just that.

Nicd<p><span>So I made this little </span><a href="https://social.ahlcode.fi/tags/UDP" rel="nofollow noopener" target="_blank">#UDP</a><span> proxy: </span><a href="https://git.ahlcode.fi/nicd/valproxy/src/commit/879287a6f419efc0b41602e764bbef0d614aeff7/index.js" rel="nofollow noopener" target="_blank">https://git.ahlcode.fi/nicd/valproxy/src/commit/879287a6f419efc0b41602e764bbef0d614aeff7/index.js</a><span><br><br>It takes in UDP packets from a </span><a href="https://social.ahlcode.fi/tags/Systemd" rel="nofollow noopener" target="_blank">#Systemd</a><span> socket and passes them on to a local target. This part seems to work well, as the server replies with its own packets. On line 168 these are written back to the original socket, using the source address and port (meaning the remote address and remote port of the client that sent the original UDP packet). To my knowledge, this should make the packets route right back to the remote client.<br><br>But currently I don't get anything back. All the replies are lost somewhere. I don't exactly know where, but I know it's after they're written to the Systemd socket and they don't appear in Wireshark on the client.<br><br>Have I misunderstood how UDP works? Or networking for that matter? Any common gotchas I should look at? (Except, of course, not doing this silly thing in the first place. But let's not get into that here.)<br><br>Please boost if you know any networking geeks. :)<br><br></span><a href="https://social.ahlcode.fi/tags/networking" rel="nofollow noopener" target="_blank">#networking</a><span> </span><a href="https://social.ahlcode.fi/tags/help" rel="nofollow noopener" target="_blank">#help</a><span> </span><a href="https://social.ahlcode.fi/tags/JavaScript" rel="nofollow noopener" target="_blank">#JavaScript</a></p>
