2024-05-01 23:25:26 | Les logiciels malveillants ciblent les routeurs pour voler les mots de passe des demandes Web Malware Targets Routers To Steal Passwords From Web Requests (lien direct) |
Les chercheurs ont récemment suivi un nouveau malware, "Sweetfish", qui cible les équipements de mise en réseau, en particulier les petits routeurs de bureau / bureau à domicile (SOHO), pour voler le matériel d'authentification trouvé dans les demandes Web qui transitent le routeur de la locale adjacenteréseau régional (LAN). Lumen Technologies & # 8217;Black Lotus Labs, qui a examiné les logiciels malveillants, a déclaré que la seiche crée un tunnel proxy ou VPN via un routeur compromis pour exfiltrer les données en contournant l'analyse basée sur la connexion anormale, puis utilise des informations d'identification volées pour accéder aux ressources ciblées. Le malware a également la capacité d'effectuer un détournement HTTP et DNS pour les connexions aux adresses IP privées, qui sont normalement associées aux communications dans un réseau interne. Les chercheurs déclarent que la plate-forme de logiciels malveillants de secteur offre une approche zéro clique pour capturer les données des utilisateurs et des appareils derrière le bord du réseau ciblé. «Toutes les données envoyées sur les équipements réseau infiltrés par ce malware sont potentiellement exposés.Ce qui rend cette famille de logiciels malveillants si insidie-the-cuttlefish-malware / "data-wpel-link =" external "rel =" nofollow nopenner noreferrer "> avertir dans un article de blog . «La seiche est en attente, reniflant passivement les paquets, n'agissant que lorsqu'il est déclenché par un ensemble de règles prédéfini.Le renifleur de paquets utilisé par la seiche a été conçu pour acquérir du matériel d'authentification, en mettant l'accent sur les services publics basés sur le cloud. » | Malware Threat Cloud Technical | APT 32 | ★★★★ |

2023-08-10 10:00:00 | Les systèmes Mac se sont transformés en nœuds de sortie proxy par adcharge Mac systems turned into proxy exit nodes by AdLoad (lien direct) |
This blog was jointly written by Fernando Martinez Sidera and Ofer Caspi, AT&T Alien Labs threat intelligence researchers.
Executive summary
AdLoad malware is still infecting Mac systems years after its first appearance in 2017. AdLoad, a package bundler, has been observed delivering a wide range of payloads throughout its existence. During AT&T Alien Labs’ investigation of its most recent payload, it was discovered that the most common component dropped by AdLoad during the past year has been a proxy application turning MacOS AdLoad victims into a giant, residential proxy botnet.
Key takeaways:
AdLoad malware is still present and infecting systems, with a previously unreported payload.
At least 150 samples have been observed in the wild during the last year.
AT&T Alien Labs has observed thousands of IPs behaving as proxy exit nodes in a manner similar to AdLoad infected systems. This behavior could indicate that thousands of Mac systems have been hijacked to act as proxy exit nodes.
The samples analyzed in this blog are unique to MacOS, but Windows samples have also been observed in the wild.
Analysis
AdLoad is one of several widespread adware and bundleware loaders currently impacting macOS. The OSX malware has been present since 2017, with big campaigns in the last two years as reported by SentinelOne in 2021 and Microsoft in 2022. As stated in Microsoft’s report on UpdateAgent, a malware delivering AdLoad through drive-by compromise, AdLoad redirected users’ traffic through the adware operators’ servers, injecting advertisements and promotions into webpages and search results with a Person-in-The-Middle (PiTM) attack.
These two previous campaigns, together with the campaign described in this blog, support the theory that AdLoad could be running a pay-per-Install campaign in the infected systems.
The main purpose of the malware has always been to act as a downloader for subsequent payloads.
It has been identified delivering a wide range of payloads (adware, bundleware, PiTM, backdoors, proxy applications, etc.) every few months to a year, sometimes conveying different payloads depending on the system settings such as geolocation, device make and model, operating system version, or language settings, as reported by SentinelOne.
In all observed samples, regardless of payload, they report an Adload server during execution on the victim’s system.
This beacon (analyzed later in Figure 3 & 4) includes system information in the user agent and the body, without any relevant response aside from a 200 HTTP response code.
This activity probably represents AdLoad\'s method of keeping count of the number of infected systems, supporting the pay-per-Install scheme.
AT&T Alien Labs™ has observed similar activity in our threat analysis systems throughout the last year, with the AdLoad malware being installed in the infected systems. However, Alien Labs is now observing a previously unreported payload being delivered to the victims. The payload corresponds to a proxy application, converting its targets into proxy exit nodes after infection. As seen in Figure 1, the threat actors behind this campaign have been very active since the beginning of 2022.

2021-10-06 19:06:00 | Inside TeamTNT\'s Impressive Arsenal: A Look Into A TeamTNT Server (lien direct) | Authored By: Tara Gould
Key Findings
Anomali Threat Research has discovered an open server to a directory listing that we attribute with high confidence to the German-speaking threat group, TeamTNT.
The server contains source code, scripts, binaries, and cryptominers targeting Cloud environments.
Other server contents include Amazon Web Services (AWS) Credentials stolen from TeamTNT stealers are also hosted on the server.
This inside view of TeamTNT infrastructure and tools in use can help security operations teams to improve detection capabilities for related attacks, whether coming directly from TeamTNT or other cybercrime groups leveraging their tools.
Overview
Anomali Threat Research has identified a TeamTNT server open to directory listing. The server was used to serve scripts and binaries that TeamTNT use in their attacks, and also for the IRC communications for their bot. The directory appears to have been in use since at least August 2021 and was in use as of October 5, 2021. The contents of the directory contain metadata, scripts, source code, and stolen credentials.
TeamTNT is a German-speaking, cryptojacking threat group that targets cloud environments. The group typically uses cryptojacking malware and have been active since at least April 2020.[1] TeamTNT activity throughout 2021 has targeted AWS, Docker, GCP, Linux, Kubernetes, and Windows, which corresponds to usual TeamTNT activity.[2]
Technical Analysis
Scripts (/cmd/)
Figure 1 - Overview of /cmd/
Contained on the server are approximately 50 scripts, most of which are already documented, located in the /cmd/ directory. The objective of the scripts vary and include the following:
AWS Credential Stealer
Diamorphine Rootkit
IP Scanners
Mountsploit
Scripts to set up utils
Scripts to setup miners
Scripts to remove previous miners
Figure 2 - Snippet of AWS Credential Stealer Script
Some notable scripts, for example, is the script that steals AWS EC2 credentials, shown above in Figure 2. The AWS access key, secret key, and token are piped into a text file that is uploaded to the Command and Control (C2) server.
Figure 3 - Chimaera_Kubernetes_root_PayLoad_2.sh
Another interesting script is shown in Figure 3 above, which checks the architecture of the system, and retrieves the XMRig miner version for that architecture from another open TeamTNT server, 85.214.149[.]236.
Binaries (/bin/)
Figure 4 - Overview of /bin
Within the /bin/ folder, shown in Figure 4 above, there is a collection of malicious binaries and utilities that TeamTNT use in their operations.
Among the files are well-known samples that are attributed to TeamTNT, including the Tsunami backdoor and a XMRig cryptominer. Some of the tools have the source code located on the server, such as TeamTNT Bot. The folder /a.t.b contains the source code for the TeamTNT bot, shown in Figures 5 and 6 below. In addition, the same binaries have been found on a TeamTNT Docker, noted in Appendix A.
