Ist man sich unsicher, ob der Anruf echt war (im Falle eines englischsprachigen Tonbands ist er das jedenfalls nicht), kann man eigenständig die Polizei (133) anrufen. Die Polizei warnt, dass man nie eine "Polizei"-Telefonnummern zurückrufen soll, wenn das in solchen Anrufen gefordert wird.

What first seemed to be a routine case of credit card theft turned out to be a much more interesting infection that leveraged both font, favicon and other less-commonly used files to pilfer credit card details. --------------------------------------------- https://blog.sucuri.net/2022/02/woocommerce-skimmer-uses-fake-fonts-and-fav… ∗∗∗ A comprehensive guide on [NTLM] relaying anno 2022 ∗∗∗ --------------------------------------------- For years now, Internal Penetration Testing teams have been successful in obtaining a foothold or even compromising entire domains through a technique called NTLM relaying. [..] This blog post aims to be a comprehensive resource that will walk through the attack primitives that continue to work today. While most will be well known techniques, some techniques involving Active Directory Certificate Services might be lesser known. --------------------------------------------- https://www.trustedsec.com/blog/a-comprehensive-guide-on-relaying-anno-2022/ ∗∗∗ Tattoo-Giveaways auf Instagram führen in eine Abo-Falle ∗∗∗ --------------------------------------------- Kriminelle versenden Nachrichten von Fake-Accounts und behaupten, dass Instagram-User bei einem Gewinnspiel gewonnen hätten.

===================== = End-of-Day report = ===================== Timeframe: Freitag 28-01-2022 18:00 − Montag 31-01-2022 18:00 Handler: Robert Waldner Co-Handler: Stephan Richter ===================== = News = ===================== ∗∗∗ Log4Shell: Eine Bestandsaufnahme ∗∗∗ --------------------------------------------- Nach der Panik wegen der größten Sicherheitslücke aller Zeiten blieb der große Knall aus. Kommt der noch oder haben wir das Gröbste überstanden? --------------------------------------------- https://heise.de/-6342536 ∗∗∗ Unseriöse Umzugsfirmen: Vorsicht bei zu günstigen Angeboten ∗∗∗ --------------------------------------------- Sie ziehen gerade um und sind auf der Suche nach einer Umzugsfirma? Unser Tipp: Lassen Sie sich nicht von Billigangeboten täuschen! Festpreisangebote von „25 Euro pro Stunde für 2 Männer inklusive LKW“ sind vollkommen unrealistisch. Dabei handelt es sich um ein Lockangebot.

The file extension means "restricted-permission message". They are used to deliver email messages between people and implement some controls applied at the recipient side. Such permissions are, by example, the right to forward or copy the original email. --------------------------------------------- https://isc.sans.edu/diary/rss/28292 ∗∗∗ Rip Raw - A tool to analyse the memory of compromised Linux systems ∗∗∗ --------------------------------------------- It is similar in purpose to Bulk Extractor, but particularly focused on extracting system Logs from memory dumps from Linux systems. This enables you to analyse systems without needing to generate a profile. This is not a replacement for tools such as Rekall and Volatility which use a profile to perform a more structured analysis of memory. --------------------------------------------- https://github.com/cado-security/rip_raw ∗∗∗ TrendNET AC2600 RCE via WAN ∗∗∗ --------------------------------------------- This blog provides a walkthrough of how to gain RCE on the TrendNET AC2600 (model TEW-827DRU specifically) consumer router via the WAN interface. There is currently no publicly available patch for these issues; therefore only a subset of issues disclosed in TRA-2021–54 will be discussed in this post. --------------------------------------------- https://medium.com/tenable-techblog/trendnet-ac2600-rce-via-wan-8926b29908a4 ∗∗∗ In eigener Sache: CERT.at sucht Verstärkung (Junior IT-Security Analyst:in, IT-Security Analyst:in, Python Entwickler:in) ∗∗∗ --------------------------------------------- Wir suchen derzeit: - Berufsein- oder -umsteiger:in mit ausgeprägtem Interesse an IT-Security zur Unterstützung bei den täglich anfallenden Routineaufgaben - IT/OT-Security Generalist:in oder Spezialist:in im Bereich Windows Security, mit Praxiserfahrung - Python Entwickler:in zur Weiterentwicklung von bestehenden Open-Source-Projekten, insbesondere IntelMQ und Tuency Details finden sich auf unserer Jobs-Seite. --------------------------------------------- https://cert.at/de/blog/2022/1/in-eigener-sache-certat-sucht-verstarkung-ju… ===================== = Vulnerabilities = ===================== ∗∗∗ VU#119678: Samba vfs_fruit module insecurely handles extended file attributes ∗∗∗ --------------------------------------------- The Samba vfs_fruit module allows out-of-bounds heap read and write via extended file attributes (CVE-2021-44142). This vulnerability allows a remote attacker to execute arbitrary code with root privileges. --------------------------------------------- https://kb.cert.org/vuls/id/119678 ∗∗∗ ABB: SECURITY - OPC Server for AC 800M - Remote Code Execution Vulnerability ∗∗∗ --------------------------------------------- ABB is aware that OPC Server for AC 800M contains a Remote Code Execution vulnerability. An authenticated remote user with low privileges who successfully exploited this vulnerability could insert and execute arbitrary code in the node running the AC800M OPC Server. --------------------------------------------- https://www02.abb.com/GLOBAL/GAD/GAD01626.NSF/0/B0A9E56BA54C9C3AC12587DB002… ∗∗∗ Lenovo Security Advisory: LEN-78122 - Intel Graphics Drivers Advisory Intel Graphics Drivers Advisory ∗∗∗ --------------------------------------------- Intel reported potential security vulnerabilities in some Intel Graphics Drivers that may allow escalation of privilege or denial of service. --------------------------------------------- https://support.lenovo.com/at/en/product_security/ps500462-intel-graphics-d… ∗∗∗ OpenSSL Security Advisory [28 January 2022] - BN_mod_exp may produce incorrect results on MIPS (CVE-2021-4160) ∗∗∗ --------------------------------------------- There is a carry propagation bug in the MIPS32 and MIPS64 squaring procedure. Many EC algorithms are affected, including some of theTLS 1.3 default curves. Impact was not analyzed in detail, because the pre-requisites for attack are considered unlikely and include reusing private keys. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be significant. However, for an attack on TLS to be meaningful, the server would have to share the DH private key among multiple clients, which is no longer an option since CVE-2016-0701. --------------------------------------------- https://openssl.org/news/secadv/20220128.txt ∗∗∗ Security updates for Monday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (apache-log4j1.2, expat, libraw, prosody, and python-nbxmpp), Fedora (chromium, hiredis, java-11-openjdk, java-latest-openjdk, lua, rust-afterburn, rust-ammonia, rust-askalono-cli, rust-below, rust-cargo-c, rust-cargo-insta, rust-fd-find, rust-insta, rust-lsd, rust-oxipng, rust-python-launcher, rust-ripgrep, rust-ron, rust-ron0.6, rust-similar, rust-similar-asserts, rust-skim, rust-thread_local, rust-tokei, vim, wpa_supplicant, and zola), Gentoo [...] --------------------------------------------- https://lwn.net/Articles/883322/ ∗∗∗ SBA-ADV-20220127-01: Shibboleth Identity Provider OIDC OP Plugin Server-Side Request Forgery ∗∗∗ --------------------------------------------- Shibboleth Identity Provider OIDC OP plugin 3.0.3 or below is prone to a server-side request forgery (SSRF) vulnerability due to an insufficient restriction of the `request_uri` parameter.

The tech giant said the attacks manifested through accounts that were not secured using multi-factor authentication (MFA), thereby making it possible for the adversary to take advantage of the target's bring-your-own-device (BYOD) policy and introduce their own rogue devices using the pilfered credentials. --------------------------------------------- https://thehackernews.com/2022/01/hackers-using-device-registration-trick.h… ∗∗∗ How to avoid an open source security nightmare ∗∗∗ --------------------------------------------- Just as it would be a mistake to say that all closed source projects are bug-free, its a mistake to say that all open source projects are security risks.

Besides its use for maintenance, it is often used by administrators for an emergency access to the server when everything "above it" (hypervisor or OS) fails and/or is unreachable. Since these kinds of platforms/interfaces are quite sensitive from the security standpoint, access to them should always be limited to relevant administrator groups only and their firmware should always be kept up to date. --------------------------------------------- https://isc.sans.edu/diary/rss/28276 ∗∗∗ German govt warns of APT27 hackers backdooring business networks ∗∗∗ --------------------------------------------- "It cannot be ruled out that the actors, in addition to stealing business secrets and intellectual property, also try to infiltrate the networks of (corporate) customers or service providers (supply chain attack)." The BfV also published indicators of compromise (IOCs) and YARA rules to help targeted German organizations to check for HyperBro infections and connections to APT27 command-and-control (C2) servers. --------------------------------------------- https://www.bleepingcomputer.com/news/security/german-govt-warns-of-apt27-h… ∗∗∗ Sysdig-Report: Container-Deployments weisen mehrheitlich Schwachstellen auf ∗∗∗ --------------------------------------------- Sysdig beobachtet einen anhaltenden Shift Left bei Container Security, viele Schwachstellen bleiben aber ungepatcht und Rechte-Konfigurationen unzureichend. --------------------------------------------- https://heise.de/-6336816 ∗∗∗ Root-Zugriff unter Linux durch Polkit-Lücke ∗∗∗ --------------------------------------------- Sicherheitsforscher haben eine Schwachstelle in Polkit entdeckt, die Rechteausweitung ermöglicht. Für die viele Distributionen sind bereits Patches verfügbar. --------------------------------------------- https://heise.de/-6338569 ∗∗∗ Fake-Shops geben sich als Shops für Warenhausauflösungen aus ∗∗∗ --------------------------------------------- Derzeit stoßen wir vermehrt auf Fake-Shops, die behaupten auf Warenhausauflösungen spezialisiert zu sein oder Überbestände von Amazon oder von Kaufhäusern zu verkaufen. Damit begründen Sie auch ihre günstigen Preise für Marken-Produkte wie KitchenAid, Weber oder DeLonghi.

Vidar is an info-stealer malware installed through spam emails and PUP, sometimes being disguised as a KMSAuto authenticator tool. It has been consistently distributed since the past, and there was a recent case of it being installed through other types of malware such as Stop ransomware. --------------------------------------------- https://asec.ahnlab.com/en/30875/ ===================== = Vulnerabilities = ===================== ∗∗∗ Multiple vulnerabilities in TransmitMail ∗∗∗ --------------------------------------------- TransmitMail is a PHP based mail form system.

These include a Denial-of-Service (DoS) of the connection to the Codesys service and the enumeration of usernames via a timing sidechannel. By exploiting these vulnerabilities, the remote usage of the Codesys services can be prevented and existing usernames on the device can be identified.

Guess what? Of course, it was and he accepted to be mentioned in a diary. Thanks to him! This time, we also have the context and how the file was used. It was delivered to the victim and this person was called beforehand to make it more confident with the file. A perfect example of social engineering attack. --------------------------------------------- https://isc.sans.edu/diary/rss/28264 ∗∗∗ Microsoft is now disabling Excel 4.0 macros by default ∗∗∗ --------------------------------------------- Microsoft says that all Excel 4.0 (XLM) macros will now be disabled by default.

GoWard proxies HTTP C2 traffic to specified Red Team servers based on the HTTP header of the traffic. GoWards intent is to help obfuscate Red Team traffic and provide some level of resiliency against Blue Team investigation and mitigation. --------------------------------------------- https://github.com/chdav/GoWard ∗∗∗ Crime Shop Sells Hacked Logins to Other Crime Shops ∗∗∗ --------------------------------------------- Up for the "Most Meta Cybercrime Offering" award this year is Accountz Club, a new cybercrime store that sells access to purloined accounts at services built for cybercriminals, including shops peddling stolen payment cards and identities, spamming tools, email and phone bombing services, and those selling authentication cookies for a slew of popular websites. --------------------------------------------- https://krebsonsecurity.com/2022/01/crime-shop-sells-hacked-logins-to-other… ∗∗∗ Dark Souls servers taken offline over hacking fears ∗∗∗ --------------------------------------------- We look at trouble in Dark Souls land after PvP servers were turned off to combat what looked like a nasty exploit.

This vulnerability is due to an integer overflow while processing Modbus traffic. An attacker could exploit this vulnerability by sending crafted Modbus traffic through an affected device.
