Il s'agit du premier script observé à l'aide d'AWS SNS, et on pense que l'acteur derrière cet outil utilise des services cloud pour envoyer des messages de phishing SMS en vrac.L'auteur du script est connu par l'alias Arduino_Das et est prolifique dans la scène du kit Phish. Le script nécessite une liste de liens de phishing nommés links.txt dans son répertoire de travail.SNS Sender prend également plusieurs arguments entrés en entrée: un fichier texte contenant une liste de clés d'accès AWS, de secrets et de région délimitées par un côlon;un fichier texte contenant une liste de numéros de téléphone à cibler;un ID de l'expéditeur, similaire à un nom d'affichage pour un message;et le contenu du message.Le script remplace toutes les occurrences de la chaîne dans la variable de contenu du message par une URL du fichier links.txt, qui arme le message en tant que SMS de phishing.L'acteur derrière cet outil a été lié à de nombreux kits de phishing utilisés pour cibler les victimes \\ 'Informations personnellement identifiables (PII) et les détails de la carte de paiement sous le couvert d'un message de laUnited States Postal Service (USPS) concernant une livraison de colis manquée. #### URL de référence (s) 1. https://www.sentinelone.com/labs/sns-sender-active-campaignes-se détendre #### Date de publication 15 février 2024 #### Auteurs) Alex Delamotte
#### Description SentinelOne researchers have discovered a new Python script called SNS Sender that uses AWS Simple Notification Service (SNS) to send bulk SMS messages for the purpose of spamming phishing links, also known as Smishing. This is the first script observed using AWS SNS, and it is believed that the actor behind this tool is using cloud services to send bulk SMS phishing messages. The script author is known by the alias ARDUINO_DAS and is prolific in the phish kit scene. The script requires a list of phishing links named links.txt in its working directory. SNS Sender also takes several arguments that are entered as input: a text file containing a list of AWS access keys, secrets, and region delimited by a colon; a text file containing a list of phone numbers to target; a sender ID, similar to a display name for a message; and the message content. The script replaces any occurrences of the string in the message content variable with a URL from the links.txt file, which weaponizes the message as a phishing SMS. The actor behind this tool has been linked to many phishing kits used to target victims\' personally identifiable information (PII) and payment card details under the guise of a message from the United States Postal Service (USPS) regarding a missed package delivery. #### Reference URL(s) 1. https://www.sentinelone.com/labs/sns-sender-active-campaigns-unleash-messaging-spam-through-the-cloud/ #### Publication Date February 15, 2024 #### Author(s) Alex Delamotte 		Spam Tool Cloud ★★★

L'arme de choix du groupe est Remcosrat, un logiciel malveillant notoire pour la surveillance et le contrôle à distance, qui a été à l'avant-garde de son arsenal d'espionnage.Cependant, dans leur dernière tournure opérationnelle, le groupe UAC-0050 a intégré une méthode de tuyau pour la communication interprodique, présentant leur adaptabilité avancée.Le vecteur d'attaque initial n'a pas encore été identifié, bien que des indications penchent vers le phishing ou les e-mails de spam.Le fichier LNK est chargé de lancer le téléchargement d'un fichier HTA.Dans ce fichier HTA se trouve unLe script VBS qui, lors de l'exécution, déclenche un script PowerShell.Ce script PowerShell s'efforce de télécharger un malveillantPayload (word_update.exe) à partir d'un serveur.Lors du lancement, word_update.exe exécute CMD.exe et partage des données malveillantes via un tuyau.Par conséquent, cela conduit au lancement d'Explorer.exe avec le remcosrat malveillant résidant à la mémoire d'Explorer.exe. La version REMCOS identifiée est 4.9.2 Pro, et elle a recueilli avec succès des informations sur la victime, y compris le nom de l'ordinateur et le nom d'utilisateur.Le remcosrat supprime les cookies et les données de connexion des navigateurs suivants: Internet Explorer, Firefox et Chrome. #### URL de référence (s) 1. https://www.uptycs.com/blog/remcos-rat-uac-0500-pipe-method #### Date de publication 4 janvier 2024 #### Auteurs) Recherche de menace de monture
#### Description The UAC-0050 threat group has been found to be using an advanced strategy that allows for a more clandestine data transfer channel, effectively circumventing detection mechanisms employed by Endpoint Detection and Response (EDR) and antivirus systems. The group\'s weapon of choice is RemcosRAT, a notorious malware for remote surveillance and control, which has been at the forefront of its espionage arsenal. However, in their latest operational twist, the UAC-0050 group has integrated a pipe method for interprocess communication, showcasing their advanced adaptability. The initial attack vector is yet to be pinpointed, though indications lean towards phishing or spam emails. The LNK file is responsible for initiating the download of an HTA file. Within this HTA file lies a VBS script that, upon execution, triggers a PowerShell script. This PowerShell script endeavors to download a malicious payload (word_update.exe) from a server. Upon launching, word_update.exe executes cmd.exe and shares malicious data through a pipe. Consequently, it leads to the launch of explorer.exe with the malicious RemcosRAT residing in the memory of explorer.exe. The Remcos version identified is 4.9.2 Pro, and it has successfully gathered information about the victim, including the computer name and username. RemcosRAT removes cookies and login data from the following browsers: Internet Explorer, Firefox, and Chrome. #### Reference URL(s) 1. https://www.uptycs.com/blog/remcos-rat-uac-0500-pipe-method #### Publication Date January 4, 2024 #### Author(s) Uptycs Threat Research 		Spam Malware Threat ★★

Un destinataire reçoit un e-mail de spam contenant un lien Web néfaste.Lorsqu'il est accessible, ce lien déclenche le téléchargement d'un fichier HTML.Dans ce fichier HTML, un fichier ISO est intégré, et ce fichier image ISO abrite un WSF (fichier de script Windows).Le fichier WSF établit par la suite des connexions avec diverses URL et procède à l'exécution de plusieurs fichiers dans des formats tels que PowerShell, VBS (VBScript) et BAT.Ces fichiers exécutés sont utilisés pour effectuer une injection de processus dans REGSVCS.EXE, un utilitaire Microsoft .NET légitime.Cette manipulation de Regsvcs.exe permet à l'attaquant de masquer secrètement leurs activités dans une application système de confiance. #### URL de référence (s) 1. https://www.mcafee.com/blogs/other-logs/mcafee-nabs/unmasking-asyncrat-new-infection-chain/ #### Date de publication 3 novembre 2023 #### Auteurs) McAfee Labs Vignesh dhatchanamoorthy Lakshya Mathur
#### Description McAfee Labs has observed a recent AsyncRAT campaign being distributed through a malicious HTML file. This entire infection strategy employs a range of file types, including PowerShell, Windows Script File (WSF), VBScript (VBS), and more, in order to bypass antivirus detection measures. A recipient receives a spam email containing a nefarious web link. When accessed, this link triggers the download of an HTML file. Within this HTML file, an ISO file is embedded, and this ISO image file harbors a WSF (Windows Script File). The WSF file subsequently establishes connections with various URLs and proceeds to execute multiple files in formats such as PowerShell, VBS (VBScript), and BAT. These executed files are employed to carry out a process injection into RegSvcs.exe, a legitimate Microsoft .NET utility. This manipulation of RegSvcs.exe allows the attacker to covertly hide their activities within a trusted system application. #### Reference URL(s) 1. https://www.mcafee.com/blogs/other-blogs/mcafee-labs/unmasking-asyncrat-new-infection-chain/ #### Publication Date November 3, 2023 #### Author(s) McAfee Labs Vignesh Dhatchanamoorthy Lakshya Mathur 		Spam ★★★
