#CheckPoint Research observed #GoBruteforcer, a modular #Go #botnet brute-forcing #Linux servers running #phpMyAdmin, #MySQL, #PostgreSQL and #FTP. Campaigns exploit AI-generated server deployments that propagate common usernames and weak defaults. The botnet converts hosts into scanners and credential harvesters, with crypto-focused runs stealing funds and expanding access through backdoors and IRC-based control.
Key takeaways Introduction GoBruteforcer is a botnet that turns compromised Linux servers into scanning and password brute-force nodes. It targets internet-exposed services such as phpMyAdmin web panels, MySQL and PostgreSQL databases, and FTP servers. Infected hosts are incorporated into the botnet and accept remote operator commands. Newly discovered weak credentials are used to steal data, […]

Source: Check Point Research (publication du 7 janvier 2026). CPR analyse une variante 2025 de GoBruteforcer (GoBrut), un botnet modulaire en Go qui transforme des serveurs Linux compromis en nœuds de scan et de brute-force, avec un intérêt marqué pour des cibles crypto. Le botnet cible des services exposés (FTP, MySQL, PostgreSQL, phpMyAdmin) et se propage via une chaîne web shell → downloader → bot IRC → bruteforcer. Deux facteurs alimentent la vague actuelle: l’usage massif d’exemples de déploiement générés par IA 🧠 qui recyclent des noms d’utilisateurs/défauts faibles (ex. appuser, myuser) et la persistance de stacks legacy comme XAMPP exposant FTP/phpMyAdmin avec un durcissement minimal. Selon CPR, >50 000 serveurs exposés pourraient être vulnérables; Shodan relève ~5,7 M de FTP, 2,23 M de MySQL et 560 k de PostgreSQL accessibles. L’ensemble de mots de passe utilisé par GoBruteforcer chevauche à 2,44% une base de 10 M de mots de passe fuités, ce qui suggère qu’environ 54,6 k MySQL et 13,7 k PostgreSQL pourraient accepter l’un des mots de passe de l’attaquant.

New #GoBruteforcer attack wave targets #crypto, #blockchain projects
from unit42, "New malware, #GoBruteforcer, is based on Golang and uses an #IRC chat bot to communicate from a victim to C2. Golang is becoming more popular with malware programmers due to its versatility."

Happy Monday folks, I hope you had a restful weekend and managed to take a breather from all things cyber! Time to get back into it though, so let me give you hand - catch up on the week’s infosec news with the latest issue of our newsletter:
https://opalsec.substack.com/p/soc-goulash-weekend-wrap-up-09e?sd=pf
#Emotet are back and are using…OneNote lures? ISO disk images? Malvertising? Nah – they’re sticking with tier tried and true TTPs – their Red Dawn maldoc template from last year; macro-enabled documents as lures, and null-byte padding to evade automated scanners.
We’ve highlighted a report on the Xenomorph #Android Banking Trojan, which added support for targeting accounts of over 400 banks; automated bypassing of MFA-protected app logins, and a Session Token stealer module. With capabilities like these becoming the norm, is it time to take a closer look at the threat Mobile Malware could pose to enterprise networks?
North Korean hackers have demonstrated yet again that they’re tracking and integrating the latest techniques, and investing in malware development. A recent campaign saw eight new pieces of malware distributed throughout the kill chain, leveraging #Microsoft #InTune to deliver payloads and an in-memory dropper to abuse the #BYOVD technique and evade EDR solutions.
A joint investigation by #Mandiant and #SonicWall has unearthed a two-year campaign by Chinese actors, enabled through exploitation of unpatched SMA100 appliances and delivery of tailored payloads. A critical vulnerability reported by #Fortinet this week helps reinforce the point that perimeter devices need to be patched with urgency, as it’s a well-documented target for Chinese-affiliated actors.
#HiatusRAT is a novel malware targeting #DrayTek routers, sniffing network traffic and proxying C2 traffic to forward-deployed implants. TTPs employed in recent #BatLoader and #Qakbot campaigns are also worth taking note of, as is #GoBruteforcer, a new malware family targeting specific web server applications to brute force logins and deploy an IRC bot for C2.
Those in Vulnerability Management should take particular note of the #Veeam vulnerability, which appears trivial to exploit and actually delivers plaintext credentials to the attacker. CISA have also taken note of nearly 40k exploit attempts of a 2 year old code-exec-as-root vulnerability in the #VMWare Cloud Foundation product in the last two months, so make sure you’re patched against it.
#Redteam members have some excellent reading to look forward to, looking at HTTP request smuggling to harvest AD credentials and persisting with a MitM Exchange server, as well as a detailed post that examines #CobaltStrike’s reflective loading capability;
The #blueteam has some great tradecraft tips from @inversecos on #Azure DFIR, as well as tools to help scan websites for malicious objects, and to combat the new #Stealc #infostealer and well-established Raccoon Stealer.
Catch all this and much more in this week's newsletter:
