===================== = End-of-Day report = ===================== Timeframe: Mittwoch 25-06-2025 18:00 − Donnerstag 26-06-2025 18:00 Handler: Michael Schlagenhaufer Co-Handler: Guenes Holler ===================== = News = ===================== ∗∗∗ Ubuntu disables Intel GPU security mitigations, promises 20% performance boost ∗∗∗ --------------------------------------------- Spectre, you may recall, came to public notice in 2018. Spectre attacks are based on the observation that performance enhancements built into modern CPUs open a side channel that can leak secrets a CPU is processing. The performance enhancement, known as speculative execution, predicts future instructions a CPU might receive and then performs the corresponding tasks before they are even called. If the instructions never come, the CPU discards the work it performed. When the prediction is correct, the CPU has already completed the task. --------------------------------------------- https://arstechnica.com/security/2025/06/ubuntu-disables-intel-gpu-security… ∗∗∗ New wave of ‘fake interviews’ use 35 npm packages to spread malware ∗∗∗ --------------------------------------------- A new wave of North Korea's 'Contagious Interview' campaign is targeting job seekers with malicious npm packages that infect dev's devices with infostealers and backdoors. --------------------------------------------- https://www.bleepingcomputer.com/news/security/new-wave-of-fake-interviews-… ∗∗∗ Hackers abuse Microsoft ClickOnce and AWS services for stealthy attacks ∗∗∗ --------------------------------------------- A sophisticated malicious campaign that researchers call OneClik has been leveraging Microsoft’s ClickOnce software deployment tool and custom Golang backdoors to compromise organizations within the energy, oil, and gas sectors. --------------------------------------------- https://www.bleepingcomputer.com/news/security/oneclik-attacks-use-microsof… ∗∗∗ Hackers turn ScreenConnect into malware using Authenticode stuffing ∗∗∗ --------------------------------------------- Threat actors are abusing the ConnectWise ScreenConnect installer to build signed remote access malware by modifying hidden settings within the client's Authenticode signature. --------------------------------------------- https://www.bleepingcomputer.com/news/security/hackers-turn-screenconnect-i… ∗∗∗ CISA is Shrinking: What Does it Mean for Cyber? ∗∗∗ --------------------------------------------- Today we are going to focus on the slimmed down profile of the Cybersecurity and Infrastructure Security Agency (CISA) under the new administration. We want to know what that means practically to cybersecurity teams. We want to explore the cost of having less coming out of CISA, and any opportunities the federal government shakeup might present for business. --------------------------------------------- https://www.darkreading.com/cybersecurity-operations/cisa-is-shrinking-what… ∗∗∗ Taming Agentic AI Risks Requires Securing Non-Human Identities ∗∗∗ --------------------------------------------- >From service accounts and Web application programming interfaces (APIs) to serverless applications and now artificial intelligence (AI) agents, the landscape of non-human identities is quickly becoming more complex.

One such threat, filesystem redirection attacks, has been a persistent vector for privilege escalation. In response, we’ve developed and deployed a new mitigation in Windows 11 called RedirectionGuard. This blog outlines how RedirectionGuard proactively closes off a major attack surface by preventing unsafe junction traversal, reinforcing our commitment to secure-by-design-principles and reducing the burden on developers and defenders. --------------------------------------------- https://msrc.microsoft.com/blog/2025/06/redirectionguard-mitigating-unsafe-… ∗∗∗ The Case of Hidden Spam Pages ∗∗∗ --------------------------------------------- Spammy posts and pages being placed on WordPress websites is one of the most common infections that we come across. The reason being is that the attack is very low-level in terms of sophistication: All that is required of the attacker is to brute force their way into the wp-admin panel; from there they just have their scripts/bots post spam posts and pages effectively achieving a blackhat SEO attack. Since an out-of-the-box WordPress website contains no protection on admin access other than a password (with no limit on the number of failed login attempts), and the admin users can often be discovered via enumeration, this remains a very popular type of spam infection on the platform. --------------------------------------------- https://blog.sucuri.net/2025/06/the-case-of-hidden-spam-pages.html ∗∗∗ nOAuth Vulnerability Still Affects 9% of Microsoft Entra SaaS Apps Two Years After Discovery ∗∗∗ --------------------------------------------- New research has uncovered continued risk from a known security weakness in Microsoft's Entra ID, potentially enabling malicious actors to achieve account takeovers in susceptible software-as-a-service (SaaS) applications. Identity security company Semperis, in an analysis of 104 SaaS applications, found nine of them to be vulnerable to Entra ID cross-tenant nOAuth abuse. --------------------------------------------- https://thehackernews.com/2025/06/noauth-vulnerability-still-affects-9-of.h… ∗∗∗ Sextortion: Inflationsgebeutelte Betrüger erhöhen Forderungen ∗∗∗ --------------------------------------------- IT-Sicherheitsforscher beobachten Preissteigerungen bei aktuellen Betrugsmaschen mit Sextortion-E-Mails.

These outdated routers are being hijacked by bad actors who use them as a stepping stone into networks, turning them into cybercriminal proxies. The threat is real, and it’s growing. --------------------------------------------- https://www.tripwire.com/state-of-security/outdated-routers-hidden-threat-n… ∗∗∗ How we turned a real car into a Mario Kart controller by intercepting CAN data ∗∗∗ --------------------------------------------- The PTP hack car is a second-hand 2016 Renault Clio that was bought because it was relatively cheap, was recent enough to feature an ‘eCall’ telematics module, small enough to fit in the garage attached to our lab and was local. It is used by our team to experiment and mess around with automotive testing on a real vehicle. It also uses a mixture of CAN and LIN for different components. --------------------------------------------- https://www.pentestpartners.com/security-blog/how-we-turned-a-real-car-into… ∗∗∗ Gefälschte Anfragen zur Änderung des Gehaltskontos im Namen von Mitarbeitenden! ∗∗∗ --------------------------------------------- Wer eine unerwartete E-Mail von einem Mitarbeitenden erhält, in der um die Änderung der Bankverbindung für das Gehaltskonto gebeten wird, sollte besonders aufmerksam sein.

System Center Configuration Manager (SCCM), now known as Microsoft Configuration Manager (ConfigMgr), is a systems management platform used for deploying software, managing updates, and enforcing configuration settings across large numbers of Windows devices. --------------------------------------------- https://www.truesec.com/hub/blog/sccm-tier-killer ∗∗∗ Decrement by one to rule them all: AsIO3.sys driver exploitation ∗∗∗ --------------------------------------------- Armory Crate and AI Suite are applications used to manage and monitor ASUS motherboards and related components such as the processor, RAM or the increasingly popular RGB lighting. These types of applications often install drivers in the system, which are necessary for direct communication with hardware to configure settings or retrieve critical parameters such as CPU temperature, fan speeds and firmware updates. Therefore, it is critical to ensure that drivers are well-written with security in mind and designed such that access to the driver interfaces are limited only to certain services and administrators. --------------------------------------------- https://blog.talosintelligence.com/decrement-by-one-to-rule-them-all/ ===================== = Vulnerabilities = ===================== ∗∗∗ WinRAR patches bug letting malware launch from extracted archives ∗∗∗ --------------------------------------------- WinRAR has addressed a directory traversal vulnerability tracked as CVE-2025-6218 that, under certain circumstances, allows malware to be executed after extracting a malicious archive. --------------------------------------------- https://www.bleepingcomputer.com/news/security/winrar-patches-bug-letting-m… ∗∗∗ Hunderte Modelle betroffen: Teils unpatchbare Lücken in Brother-Druckern entdeckt ∗∗∗ --------------------------------------------- Sicherheitsforscher von Rapid7 haben zahlreiche Multifunktionsdrucker auf mögliche Sicherheitslücken untersucht.

Prometei refers to both the botnet and the malware family used to operate it. This malware family, which includes both Linux and Windows variants, allows attackers to remotely control compromised systems for cryptocurrency mining (particularly Monero) and credential theft. This article focuses on the resurgence of the Linux variant. --------------------------------------------- https://unit42.paloaltonetworks.com/prometei-botnet-2025-activity/ ∗∗∗ Joint Analysis by AhnLab and NCSC on TA-ShadowCricket: Emerging Malware Trends and IRC Server Tracking ∗∗∗ --------------------------------------------- ince November 2024, AhnLab has been working with the NCSC to analyze the malicious IRC server and related malware to classify the unidentified threat actor as Larva-24013 and trace their activities, and has confirmed their association with the Shadow Force group. AhnLab manages malicious activities in four stages through the “Threat Actor Naming and Taxonomy,” classifying threat actors as “Larva” (unidentified threat actors) and “Arthropod” (identified threat actors). Following AhnLab’s threat actor taxonomy and naming convention, the threat actor has been identified and named TA-ShadowCricket. --------------------------------------------- https://asec.ahnlab.com/en/88137/ ∗∗∗ Scammers Insert Fake Support Numbers on Real Apple, Netflix, PayPal Pages ∗∗∗ --------------------------------------------- Cybercriminals are finding clever new ways to trick people, even on the official websites of major companies.

First tracked in January 2025, this threat uniquely combines social engineering tricking people with specially built malicious software. --------------------------------------------- https://hackread.com/mocha-manakin-malware-nodeinitrat-via-clickfix-attack/ ∗∗∗ What’s in an ASP? Creative Phishing Attack on Prominent Academics and Critics of Russia ∗∗∗ --------------------------------------------- In cooperation with external partners, Google Threat Intelligence Group (GTIG) observed a Russia state-sponsored cyber threat actor impersonating the U.S. Department of State. From at least April through early June 2025, this actor targeted prominent academics and critics of Russia, often using extensive rapport building and tailored lures to convince the target to set up application specific passwords (ASPs). Once the target shares the ASP passcode, the attackers establish persistent access to the victim’s mailbox. Two distinct campaigns are detailed in this post. This activity aligns with Citizen Lab’s recent research on social engineering attacks against ASPs, another useful resource for high risk users. --------------------------------------------- https://cloud.google.com/blog/topics/threat-intelligence/creative-phishing-… ∗∗∗ Same Sea, New Phish: Russian Government-Linked Social Engineering Targets App-Specific Passwords ∗∗∗ --------------------------------------------- In recent years, users’ familiarity with common phishing tactics, increasingly advanced detection and blocking by platforms, and the rise in use of Multi-Factor Authentication (MFA), have all contributed to changes in the ways that attackers phish accounts. The introduction of more secure forms of MFA, such as hardware security keys, has also closed off certain avenues of social engineering. . --------------------------------------------- https://citizenlab.ca/2025/06/russian-government-linked-social-engineering-… ∗∗∗ Betrüger nutzen Briefpost zur Abzocke der Ledger-Wallet ∗∗∗ --------------------------------------------- Wer mit Krypto-Währungen und Assets hantiert, hat sicherlich zumindest mit Hardware-Wallets wie der von Ledger geliebäugelt.

"Ein Logikfehler kann bei der Verarbeitung von bösartig präparierten Fotos oder Videos auftreten, die mittels eines iCloud-Links geteilt wurden", schreiben die Entwickler dazu (CVE-2025-43200 / EUVD-2025-18428, CVSS steht noch aus, Risikoeinstufung fehlt derzeit). Sie erklären weiter: "Apple weiß von einem Bericht, demzufolge dieses Problem in einem extrem ausgeklügelten Angriff gegen bestimmte Zielpersonen ausgenutzt worden sein könnte." Der Schwachstelleneintrag stammt vom Montag dieser Woche. Sicherheitsmitteilungen zu den diversen Betriebssystemen und -versionen hat Apple hingegen bereits am Donnerstag vergangener Woche aktualisiert oder neu veröffentlicht. --------------------------------------------- https://heise.de/-10449241 ∗∗∗ Cross-Site Scripting (XSS) Schwachstelle CVE-2025-4123 in Grafana ∗∗∗ --------------------------------------------- In der Open-Source-Software Grafana wurde die Tage eine Cross-Site Scripting (XSS) Schwachstelle CVE-2025-4123 öffentlich.

About Two Weeks, (Tue, Jun 17th) ∗∗∗ --------------------------------------------- I recently added an account to my Google Workspace domain (montance[dot]com). Friday, May 16th, 10:10 am, to be exact. Something interesting to note about the domain configuration is there’s a catchall account in place, so all email addresses are valid. Starting May 28th the new account started receiving targeted phishing email messages. [..] Nothing especially surprising, but a reminder that they’re watching for opportunities. Someone new at the company and eager to appear responsive seems like a good phishing target! --------------------------------------------- https://isc.sans.edu/diary/rss/32052 ∗∗∗ TP-Link Router Flaw CVE-2023-33538 Under Active Exploit, CISA Issues Immediate Alert ∗∗∗ --------------------------------------------- The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a high-severity security flaw in TP-Link wireless routers to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation.
