crond, sshd, polkitd: la backdoor nordcoreana Ted infetta i demoni Linux nascosta dentro HAProxy
Rapid7 documenta una campagna APT37 che troianizza HAProxy e i servizi di sistema Linux (crond, sshd, polkitd, agetty, atd) per spiare aziende sudcoreane di media e automotive. La backdoor Ted e il RAT companion CurlRAT restano invisibili per mesi grazie a timestamp falsificati e log ripuliti chirurgicamente.
DPRK APTs: Ted backdoor and curlRAT target South Korean media and automotive sectors
A previously undocumented Linux toolkit has been targeting South Korean automotive and media organizations with minimal detection since early 2025. The campaign employs a HAProxy instance called ted backdoor, compiled within the victim's existing HAProxy version 2.8.12, alongside trojanized versions of crond, agetty, atd, sshd, and polkitd. This sophisticated framework enables remote command execution, malicious script injection into web traffic, credential harvesting, and long-term surveillance. The ted backdoor uses HAProxy's native filter API and internal structures to intercept SSL-decrypted HTTP traffic while maintaining legitimate load balancing operations. Operating alongside are an SSH keylogger, a curl-based RAT with HAProxy health monitoring capabilities, and a deployment stager. The toolkit is attributed with medium confidence to DPRK APTs based on targeting patterns, simple XOR-based encryption schemes, custom substitution ciphers, and C2 infrastructure associated with APT37.

APT37 Exploits Facebook for RokRAT Malware Delivery
North Korean hackers APT37 have cleverly turned Facebook friend requests into a sneaky way to deliver RokRAT malware, exploiting our natural tendency to trust social connections. By accepting a friend request, victims unwittingly open the door to a remote access trojan that can compromise their device.

APT37 abusing .LNK files with GitHub-based C2 in targeted campaign against South Korean organizations and supply chain partners. Malicious shortcuts execute PowerShell, deploy XenoRAT for remote access and keylogging. Detection challenge: legitimate GitHub traffic masks command execution.

APT37 Adds New Capabilities for Air-Gapped Networks
#APT37 #RESTLEAF #SNAKEDROPPER #THUMBSBD #VIRUSTASK #BLUELIGHT
https://threatlabz.zscaler.com/blogs/security-research/apt37-adds-new-capabilities-air-gapped-networks
APT37’s Ruby Jumper campaign demonstrates a mature approach to air-gap traversal.
Observed tradecraft includes:
• LNK-based initial execution
• Embedded PowerShell payload extraction
• Ruby interpreter abuse (v3.3.0)
• Scheduled task persistence (5-minute interval)
• USB-based covert bidirectional C2
• Multi-stage backdoor deployment
Toolset: RESTLEAF, SNAKEDROPPER, THUMBSBD, VIRUSTASK, FOOTWINE, BLUELIGHT.
The removable media relay model enables:
– Command staging offline
– Data exfiltration without internet access
– Lateral spread across isolated systems
– Surveillance via Windows spyware
This reinforces a critical point:
Air-gap controls must extend beyond physical disconnection — including USB governance, device auditing, behavioral monitoring, and strict runtime execution policies.
Are critical infrastructure operators prepared for USB-mediated C2 relays?

South Korean researchers (Genians) report that APT37 is abusing Google Find Hub to track victims and remotely wipe Android devices.
The attackers use phished Google credentials to access legitimate Find Hub functions - no exploit involved.
Google has confirmed this and advises enabling 2-Step Verification or passkeys.
Credential security remains the weakest link in most modern attacks.

Analysis of malicious HWP cases of 'APT37' group distributed through K messenger
The report details a sophisticated APT attack targeting South Korea, utilizing spear-phishing techniques and malicious HWP files distributed through a popular Korean messenger service. The APT37 group exploited trust-based tactics, using compromised accounts to spread malware through group chats. The malicious files contained OLE objects that executed PowerShell commands and shellcode, ultimately deploying the RoKRAT malware. This file-less attack method allowed for information gathering and potential remote control of infected systems. The attackers used pCloud for data exfiltration and command-and-control communication. The report emphasizes the importance of endpoint detection and response (EDR) systems to combat such evolving threats.

Happy Tuesday everyone!
#APT37, aka #ScarCruft, is at it again! SentinelOne researchers noticed that they are targeting media organizations and others that are associated with North Korean affairs. The group leverages .LNK files, zip files, and phishing emails.
I found this article most interesting because of the multiple types of file formats that were used, to include .bat and .dat files, involved in the campaign. They also use a custom backdoor known as #RokRat to aid in their attack. This is a great article and worth the time! Enjoy and Happy Hunting!

Die vom nordkoreanischen Staat gesponserte Hackergruppe #ScarCruft (#APT37) hat die IT-Infrastruktur und den E-Mail-Server von NPO Mashinostroyeniya gehackt.
NPO Mashinostroyeniya ist ein russischer Konstrukteur und Hersteller von Orbitalfahrzeugen, Raumfahrzeugen und taktischen Verteidigungs- und Angriffsraketen, die von der russischen und indischen Armee eingesetzt werden.
Just uploaded my #APT37 #ROKRAT shellcode decrypter script to my github. Hope this helps malware researchers out there
https://github.com/0x0v1/MalwareRETools/tree/main/APT37/ROKRAT
I just published a script that will assist malware researchers looking at #APT37's #ROKRAT to decode the PS reflection portion of the loader phase. It gives analysts the option to pull shellcode from the payload delivery host quickly for timely analysis.
https://github.com/0x0v1/MalwareRETools/tree/main/APT37/ROKRAT
I will later publish a script to deencrypt the shellcode for analysis - just need to clean a few things up in it.
Happy Tuesday everyone! #APT37 is the topic of today's #readoftheday, specifically ThreatMon takes a deep-dive into the #RokRat malware, which is a remote access trojan (RAT). Enjoy and Happy Hunting!
