===================== = End-of-Day report = ===================== Timeframe: Mittwoch 26-05-2021 18:00 − Donnerstag 27-05-2021 18:00 Handler: Dimitri Robl Co-Handler: Stephan Richter ===================== = News = ===================== ∗∗∗ Achtung: Kriminelle fälschen „Grünen Pass“! ∗∗∗ --------------------------------------------- In Österreich wird bald der „Grüne Pass“ eingeführt, der den Zugang zu Gastronomie und körpernahen Dienstleistungen erleichtern soll. Dieser ist erst in der zweiten Juni-Woche verfügbar, doch Kriminelle verbreiten bereits jetzt eine „Variante“ des Grünen Passes. Wir gehen davon aus, dass dabei personenbezogene Daten abgegriffen werden. Wer die unseriöse App als gültigen Impf-, Test- oder Genesungsnachweis verwendet, könnte könnte sich außerdem strafbar machen. --------------------------------------------- https://www.watchlist-internet.at/news/achtung-kriminelle-faelschen-gruenen… ∗∗∗ Exploit veröffentlicht: Gefixte WebKit-Schwachstelle steht auf iPhones offen ∗∗∗ --------------------------------------------- Ein Patch im Open-Source-Unterbau aller iOS-Browser ist selbst nach Wochen noch nicht in Apples Betriebssysteme eingeflossen, warnt eine Sicherheitsfirma. --------------------------------------------- https://heise.de/-6055716 ∗∗∗ BazaLoader Masquerades as Movie-Streaming Service ∗∗∗ --------------------------------------------- The website for “BravoMovies” features fake movie posters and a FAQ with a rigged Excel spreadsheet for “cancelling” the service, but all it downloads is malware. --------------------------------------------- https://threatpost.com/bazaloader-fake-movie-streaming-service/166489/ ∗∗∗ “Unpatchable” vuln in Apple’s new Mac chip – what you need to know ∗∗∗ --------------------------------------------- Its all over the news! The bug you cant fix! Fortunately, you dont need to. We explain why. --------------------------------------------- https://nakedsecurity.sophos.com/2021/05/27/unpatchable-vuln-in-apples-new-… ∗∗∗ Analysis report of the Facefish rootkit ∗∗∗ --------------------------------------------- In Feb 2021, we came across an ELF sample using some CWP’s Ndays exploits, we did some analysis, but after checking with a partner who has some nice visibility in network traffic in some China areas, we discovered there is literarily 0 hit for the C2 traffic. --------------------------------------------- https://blog.netlab.360.com/ssh_stealer_facefish_en/ ∗∗∗ All your Base are...nearly equal when it comes to AV evasion, but 64-bit executables are not, (Thu, May 27th) ∗∗∗ --------------------------------------------- Malware authors like to use a variety of techniques to avoid detection of their creations by anti-malware tools. As the old saying goes, necessity is the mother of invention and in the case of malware, it has lead its authors to devise some very interesting ways to hide from detection over the years - from encoding of executable files into valid bitmap images[1] to multi-stage encryption of malicious payloads[2] and much further. --------------------------------------------- https://isc.sans.edu/diary/rss/27466 ∗∗∗ Saving Your Access ∗∗∗ --------------------------------------------- After revisiting old internal discussions, an area of interest was the possibility of using screensavers for persistence on macOS. This is an established persistence method on Windows, as noted on the MITRE ATT&CK page. --------------------------------------------- https://posts.specterops.io/saving-your-access-d562bf5bf90b ∗∗∗ Crimes of Opportunity: Increasing Frequency of Low Sophistication Operational Technology Compromises ∗∗∗ --------------------------------------------- Attacks on control processes supported by operational technology (OT) are often perceived as necessarily complex. This is because disrupting or modifying a control process to cause a predictable effect is often quite difficult and can require a lot of time and resources. However, Mandiant Threat Intelligence has observed simpler attacks, where actors with varying levels of skill and resources use common IT tools and techniques to gain access to and interact with exposed OT systems. --------------------------------------------- https://www.fireeye.com/blog/threat-research/2021/05/increasing-low-sophist… ===================== = Vulnerabilities = ===================== ∗∗∗ HPE fixes critical zero-day vulnerability disclosed in December ∗∗∗ --------------------------------------------- Hewlett Packard Enterprise (HPE) has released a security update to address a zero-day remote code execution vulnerability disclosed last year, in December. --------------------------------------------- https://www.bleepingcomputer.com/news/security/hpe-fixes-critical-zero-day-… ∗∗∗ Drupal: Update schließt Cross-Site-Scripting-Lücke in mehreren CMS-Versionen ∗∗∗ --------------------------------------------- Die Programmbibliothek CKEditor, die vom Drupal-Core verwendet wird, barg unter bestimmten Umständen Angriffsmöglichkeiten.

===================== = End-of-Day report = ===================== Timeframe: Dienstag 25-05-2021 18:00 − Mittwoch 26-05-2021 18:00 Handler: Dimitri Robl Co-Handler: Robert Waldner ===================== = News = ===================== ∗∗∗ Kaspersky Security Bulletin 2020-2021. EU statistics ∗∗∗ --------------------------------------------- The statistics in this report cover the period from May 2020 to April 2021, inclusive. --------------------------------------------- https://securelist.com/kaspersky-security-bulletin-2020-2021-eu-statistics/… ∗∗∗ Smart lighting security ∗∗∗ --------------------------------------------- RJ45 connections delivering Power over Ethernet are becoming prevalent in light fittings, a result of the lower power demands from LED fittings. This creates potential for uninformed installers to inadvertently bridge network security controls through connecting the light fittings to existing networking equipment. ... Radio protocols can also lead to compromise if not done securely; Bluetooth Classic, BLE, Z-Wave and many other protocols can be exploited if not configured correctly. --------------------------------------------- https://www.pentestpartners.com/security-blog/smart-lighting-security/ ∗∗∗ The Attack Path Management Manifesto ∗∗∗ --------------------------------------------- The primary goal of Attack Path Management (APM) is to directly solve the problem of Attack Paths. Today, the problem of Attack Paths is felt most acutely in the world of Microsoft Active Directory and Azure Active Directory. These platforms provide the greatest payoff for attackers, since taking control of the fundamental identity platform for an enterprise grants full control of all users, systems, and data in that enterprise --------------------------------------------- https://posts.specterops.io/the-attack-path-management-manifesto-3a3b117f5e5 ∗∗∗ CVE-2021-22909- Digging into a Ubiquiti Firmware Update bug ∗∗∗ --------------------------------------------- Back In February, Ubiquiti released a new firmware update for the Ubiquiti EdgeRouter, fixing CVE-2021-22909/ZDI-21-601. The vulnerability lies in the firmware update procedure and allows a man-in-the-middle (MiTM) attacker to execute code as root on the device by serving a malicious firmware image when the system performs an automatic firmware update. ... The impact of this vulnerability is quite nuanced and worthy of further discussion. --------------------------------------------- https://www.thezdi.com/blog/2021/5/24/cve-2021-22909-digging-into-a-ubiquit… ===================== = Vulnerabilities = ===================== ∗∗∗ VU#799380: Devices supporting Bluetooth Core and Mesh Specifications are vulnerable to impersonation attacks and AuthValue disclosure ∗∗∗ --------------------------------------------- Devices supporting the Bluetooth Core and Mesh Specifications are vulnerable to impersonation attacks and AuthValue disclosure that could allow an attacker to impersonate a legitimate device during pairing. --------------------------------------------- https://kb.cert.org/vuls/id/799380 ∗∗∗ CVE-2020-14145 ∗∗∗ --------------------------------------------- A vulnerability in OpenSSH <= 8.6 allows a man in the middle attack to determine, if a client already has prior knowledge of the remote hosts fingerprint. Using this information leak it is possible to ignore clients, which will show an error message during an man in the middle attack, while new clients can be intercepted without alerting them of the man in the middle attack. [...] At the moment, the only option to mitigate this vulnerability is to set HostKeyAlgorithms in your config file. --------------------------------------------- https://docs.ssh-mitm.at/CVE-2020-14145.html ∗∗∗ Sicherheitsupdates: Kritische Schadcode-Lücke bedroht VMware vCenter Server ∗∗∗ --------------------------------------------- Die Servermanagementsoftware vCenter Server ist verwundbar.

Whether it was as an entry point or target, I was not interested, since I typically had far better targets and could compromise the networks anyway. However, the times have changed, internal environments are much more restricted, not many services are exposed, and applications are the main reason for the tests.

The idea is to make our life more difficult (read: "frustrating"). There are plenty of techniques that can be implemented but it's an ever-ongoing process. --------------------------------------------- https://isc.sans.edu/diary/rss/27444 ∗∗∗ Double-Encrypting Ransomware ∗∗∗ --------------------------------------------- This seems to be a new tactic: Emsisoft has identified two distinct tactics. In the first, hackers encrypt data with ransomware A and then re-encrypt that data with ransomware B. The other path involves what Emsisoft calls a “side-by-side encryption” attack, in which attacks encrypt some of an organization’s systems with ransomware A and others with ransomware B.

In the same way, most popular tools today have a "dockerized" version ready to use, sometimes maintained by the developers themselves, sometimes maintained by third parties. An example is the Docker container that I created with all Didier’s tools. Today, we are also facing a new threat: supply chain attacks (think about Solarwinds or, more recently, CodeCov).
