Toy Ghouls’ new toy: the GenieLocker ransomware

GenieLocker is a new ransomware family active since March 2026, targeting organizations in the Russian Federation, primarily in manufacturing. Attributed to the financially motivated Toy Ghouls group (also known as Bearlyfy, Labubu, and Laboo.boo), this custom-designed ransomware marks a shift from their previous reliance on third-party encryption tools like RedAlert, LockBit, and Babuk. GenieLocker exists in two variants: PE builds for Windows and ELF builds for Linux and ESXi. The Windows version features sophisticated capabilities including process termination, service shutdown, anti-debugging techniques, and advanced encryption using the libsodium library with XChaCha20-Poly1305 algorithm. Initial access typically occurs through compromised VPN credentials from trusted partners, followed by deployment of tools like Mimikatz, SoftPerfect Network Scanner, and SSH utilities for lateral movement before deploying ransomware using PsExec and PAExec.

Spirals: New Stealthy Ransomware Deployed Against Asian IT Company

A previously unseen ransomware family named Spirals was deployed in a double extortion attack against an IT services company in South Asia in June 2026. The Rust-based payload demonstrated sophisticated capabilities including defense evasion, encryption, lateral movement, and privilege escalation. Attackers gained initial access through a compromised internet-facing IIS web server via an ASP.NET web shell, moving rapidly to deploy ransomware within 24 hours. They established persistence using multiple tunneling tools, disabled endpoint security, harvested credentials through SAM hive and LSASS dumps, and deployed reverse-SOCKS proxies for covert command-and-control. The ransomware was distributed across the network using PsExec, encrypting files with AES-128 keys and threatening data publication within six days. The skilled execution suggests potential for wider campaigns, though the threat actor remains unidentified.

Ledger — прохождение сложной машины от Tryhackme

Ledger — это сложная машина Windows на TryHackMe, в центре которой находится неправильная конфигурация служб сертификатов Active Directory (AD CS). Первоначальная разведка выявляет контроллер домена ( labyrinth.thm.local ) с включенной аутентификацией SMB null и LDAP, раскрывающим учетные данные пользователя в примечаниях. Через certipy-ad находим шаблон сертификата ServerAuth , который уязвим к ESC1 , что позволяет любому аутентифицированному пользователю запросить сертификат, выдавая себя за администратора домена. Хэш NT администратора извлекается из поддельного сертификата, а psexec предоставляет командную оболочку NT AUTHORITY SYSTEM. Альтернативный путь эксплуатации через аутентификацию LDAP Schannel для случаев, когда Kerberos PKINIT не срабатывает.

Wprowadzenie do Sysinternals – PSTools/PsExec

W pracy z systemami Windows kluczowy jest dostęp do narzędzi umożliwiających zdalną administrację. Choć nowoczesne rozwiązania, takie jak PowerShell Remoting, dobrze spełniają te funkcje, ich wykorzystanie często jest ograniczone przez polityki bezpieczeństwa lub rozwiązania EDR (Endpoint Detection & Response – wykrywanie i reagowanie w punktach końcowych). W takich sytuacjach można...

#psexec can be detected by .key files:

"Starting with PsExec v2.30 [...], anytime a PsExec command is executed, a .key file gets written to the file system and will be recorded in the USN Journal on the target system. It will follow this naming convention: PSEXEC-[Source Hostname]-[8 Unique Characters].key and will be located at the C:\Windows directory." [1]

Pass The Hash? Да легко! + артефакты

🔥 Атака Pass The Hash позволяет злоумышленнику повторно использовать NT хэш для входа систему, избегая ввода пароля и используя протокол NTLM для авторизации, вместо базового Kerberos. Но как она делается и, самое главное, детектится в домене?...

Another week, another newsletter - catch up on the week's infosec news here:

https://opalsec.substack.com/p/soc-goulash-weekend-wrap-up-240423-300423

Researchers have found that nearly two years on, 2 in 3 installs of #Apache #Superset are still using default Flask Secret Keys - a configuration flaw which would allow an attacker to forge session cookies and access said servers with full administrative privileges.

#Kritec is a commodity #skimmer found installed on compromised #Magecart sites, with its code heavily obfuscated and customised to match the site's aesthetic in order to con users out of credit card details.

#FIN7 look to be popping instances of the #Veeam backup software that are unpatched for a recent vulnerability; a revised #ViperSoftX #infostealer now targets #1password and #keepass password vaults, and #TA505 deliver a new infostealer through a #GoogleAds campaign

#LockBit & #CL0P ransomware affiliates have been abusing a month-old vulnerability in the #PaperCut print management software to drop ransomware. With the cat out of the bag, security researchers have decided now is a great time to drop a PoC exploit on Github - I mean, why not let the skiddies get in on the action too, right?

The #blueteam have some great research worth reading on #Smishing via #AWS; detections for #SliverC2 and different implementations of #PsExec, as well as #Sigma integration for #SentinelOne and a #KQL hack for monitoring LOLDrivers.

Have a great week ahead folks, I hope this newsletter proves helpful!
