StoneBear :potion_genderqueer:<p>Dear Actual Humans (and ferals and cryptids too, as long as you're a carbon-based life form): Looking for simple, inexpensive, EU-based hosting. Primarily right now I want to host some _private_ git repos (which is why I haven't already run to Codeberg - this is just piddly stuff I've been messing with that's nobody else's business but my own, but having a copy of your code offsite is good opsec, so...) and maybe eventually an Nextcloud instance. (if I can get ssh + Nextcloud inexpensively, I'm open to that...) If I'm really feeling froggy I might want Jitsi eventually but that'll be a minute... </p><p><a href="https://hachyderm.io/tags/hosting" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>hosting</span></a> <a href="https://hachyderm.io/tags/NextcloudHosting" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>NextcloudHosting</span></a> <a href="https://hachyderm.io/tags/git" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>git</span></a> <a href="https://hachyderm.io/tags/GiveUpGitHub" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GiveUpGitHub</span></a> <a href="https://hachyderm.io/tags/ssh" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ssh</span></a> <a href="https://hachyderm.io/tags/fuckAI" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fuckAI</span></a> <a href="https://hachyderm.io/tags/fuckBigTech" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fuckBigTech</span></a></p>

OTX Bot<p>A New Threat Actor Targeting Geopolitical Hotbeds</p><p>Bitdefender Labs has uncovered a new threat actor group named Curly COMrades, operating since mid-2024 to support Russian interests. The group targets critical organizations in countries experiencing geopolitical shifts, focusing on judicial and government bodies in Georgia and an energy distribution company in Moldova. Their primary objective is to maintain long-term network access and steal credentials. The attackers use proxy tools like Resocks, SSH, and Stunnel to establish multiple entry points, and deploy a new backdoor called MucorAgent. They also utilize compromised legitimate websites as traffic relays to complicate detection. The group's tactics include credential theft, lateral movement, and data exfiltration, employing both custom and open-source tools.</p><p>Pulse ID: 689b565c2e425682d6ad72ef<br>Pulse Link: <a href="https://otx.alienvault.com/pulse/689b565c2e425682d6ad72ef" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">otx.alienvault.com/pulse/689b5</span><span class="invisible">65c2e425682d6ad72ef</span></a> <br>Pulse Author: AlienVault<br>Created: 2025-08-12 14:57:32</p><p>Be advised, this data is unverified and should be considered preliminary.

Maybe other secrets too. <br>At work I am forced to rotate everything every 3 months but they have entire systems to remind &amp; facilitate it, finally they have support engineers who can reset my password. If I mess up in my personal life, I'd be really stuck.</p>
