They were fixed as CVE-2021-25337, CVE-2021-25369, CVE-2021-25370. To ensure your Samsung device is up-to-date under settings you can check that your device is running SMR Mar-2021 or later. As defenders, in-the-wild exploit samples give us important insight into what attackers are really doing. We get the “ground truth” data about the vulnerabilities and exploit techniques they’re using, which then informs our further research and guidance to security teams on what could have the biggest impact or return on investment. To do this, we need to know that the vulnerabilities and exploit samples were found in-the-wild. --------------------------------------------- https://googleprojectzero.blogspot.com/2022/11/a-very-powerful-clipboard-sa… ∗∗∗ What Is Cross-Origin Resource Sharing (CORS)? ∗∗∗ --------------------------------------------- Thanks to the rapid growth of JavaScript frameworks like Angular, React, and Vue, Cross-Origin Resource Sharing (CORS) has become a popular word in the developer’s vocabulary — and for good reason. It’s common practice for modern web applications to load resources from multiple domains. But accessing these website resources from different origins requires a thorough understanding of CORS. In this post, we’ll take a look at what CORS is and why proper implementation is an important component of building secure websites and applications. We’ll also examine some common examples of how to use CORS, dive into preflight requests, and discuss how to protect your website against attacks. --------------------------------------------- https://blog.sucuri.net/2022/11/what-is-cross-origin-resource-sharing-cors.… ∗∗∗ Multi-factor auth fatigue is real – and its why you may be in the headlines next ∗∗∗ --------------------------------------------- Overwhelmed by waves of push notifications, worn-down users inadvertently let the bad guys in Analysis The September cyberattack on ride-hailing service Uber began when a criminal bought the stolen credentials of a company contractor on the dark web. --------------------------------------------- https://go.theregister.com/feed/www.theregister.com/2022/11/03/mfa_fatigue_… ∗∗∗ Inside the V1 Raccoon Stealer’s Den ∗∗∗ --------------------------------------------- Team Cymru’s S2 Research Team has blogged previously on the initial Raccoon stealer command and control methodology (Raccoon Stealer - An Insight into Victim “Gates”), which utilized “gate” IP addresses to proxy victim traffic / data to static threat actor-controlled infrastructure.

[...] Currently no complete overview of vulnerable products is available. Please see https://github.com/NCSC-NL/OpenSSL-2022/blob/main/software/README.md for a list of products that are known to be vulnerable. The list is a work in progress. --------------------------------------------- https://github.com/NCSC-NL/OpenSSL-2022 ∗∗∗ Upcoming Critical OpenSSL Vulnerability: What will be Affected?, (Thu, Oct 27th) ∗∗∗ --------------------------------------------- Some here may still remember Heartbleed. Heartbleed was a critical OpenSSL vulnerability that surprised many organizations, and patching the issue was a major undertaking. Heartbleed caused OpenSSL and other open-source projects to rethink how they address security issues and communicate with their users. OpenSSL started to pre-announce any security updates about a week ahead of time. This week, OpenSSL announced they would release OpenSSL 3.0.7 this coming Tuesday. It will fix a critical vulnerability [1]. --------------------------------------------- https://isc.sans.edu/diary/rss/29192 ∗∗∗ APT10: Tracking down LODEINFO 2022, part I ∗∗∗ --------------------------------------------- The first part of this report will provide technical analysis of the new infection methods such as SFX files and DOWNIISSA, a new downloader shellcode used to deploy the LODEINFO backdoor. --------------------------------------------- https://securelist.com/apt10-tracking-down-lodeinfo-2022-part-i/107742/ ∗∗∗ APT10: Tracking down LODEINFO 2022, part II ∗∗∗ --------------------------------------------- In the second part of this report, we discuss improvements made to the LODEINFO backdoor shellcode in 2022. --------------------------------------------- https://securelist.com/apt10-tracking-down-lodeinfo-2022-part-ii/107745/ ∗∗∗ NMAP without NMAP - Port Testing and Scanning with PowerShell, (Mon, Oct 31st) ∗∗∗ --------------------------------------------- Ever needed to do a portscan and didn't have nmap installed? I've had this more than once on an internal pentest or more often just on run-rate "is that port open? / is there a host firewall in the way?" testing. --------------------------------------------- https://isc.sans.edu/diary/rss/29202 ∗∗∗ WordPress Vulnerability & Patch Roundup October 2022 ∗∗∗ --------------------------------------------- [...] To help educate website owners on emerging threats to their environments, we’ve compiled a list of important security updates and vulnerability patches for the WordPress ecosystem this past month. --------------------------------------------- https://blog.sucuri.net/2022/10/wordpress-vulnerability-patch-roundup-octob… ∗∗∗ Hardware Trojans Under a Microscope ∗∗∗ --------------------------------------------- While the security industry generally focuses on software cyber attacks, we can’t forget the security impact of lower level hardware flaws, such as those that affect semiconductors. --------------------------------------------- https://ryancor.medium.com/hardware-trojans-under-a-microscope-bf542acbcc29 ∗∗∗ What I learnt from reading 217* Subdomain Takeover bug reports. ∗∗∗ --------------------------------------------- My two prior blogs, What I Learnt From Reading 220 IDOR bug reports, and What I Learnt From Reading 126 Information Disclosure Writeups*, were well received, so I’m continuing the series. I once more scraped ALL 143 SDTO bug reports from hackerone, and 74 detailed write-ups, then went into hiding as I read and took notes on them. I’m here to show you my actionable findings, and show you how to properly hunt for SDTOs. --------------------------------------------- https://medium.com/@nynan/what-i-learnt-from-reading-217-subdomain-takeover… ∗∗∗ Free Micropatches For Bypassing MotW Security Warning with Invalid Signature (0day) ∗∗∗ --------------------------------------------- Nine days ago we issued micropatches for a vulnerability that allows attackers to bypass the warning Windows normally present to users when they try to open a document or executable obtained from an untrusted source (Internet, email, USB key, network drive). That vulnerability, affecting all supported and many legacy Windows versions, still has no official patch from Microsoft so our (free!) patches are the only actual patches in existence as of this writing. On the very same day we issued these micropatches, Will Dormann - who researched said vulnerability - replied to a tweet by another security researcher, Patrick Schläpfer. Patrick works at HP Wolf Security where they analyzed the Magniber Ransomware and wrote a detailed analysis of its working. Will asked Patrick about the ZIP files used in the malware campaign to see if they were exploiting the same vulnerability or employing some other trick to bypass the "Mark of the Web". [...] And so a new 0day - already exploited in the wild - was revealed. --------------------------------------------- https://blog.0patch.com/2022/10/free-micropatches-for-bypassing-motw.html ∗∗∗ The Defender’s Guide to the Windows Registry ∗∗∗ --------------------------------------------- Welcome to the Defender’s Guide. This is a series of blog posts designed to give you a ground-up start to defending a specific technology from potential attackers. While a lot of this information may be redundant to a more seasoned information security personnel, even the best of us rely on Google and blog posts to get information. These posts are designed to be a one-stop shop, bringing a lot of that information together. --------------------------------------------- https://posts.specterops.io/the-defenders-guide-to-the-windows-registry-feb… ∗∗∗ Banking Trojan Techniques: How Financially Motivated Malware Became Infrastructure ∗∗∗ --------------------------------------------- Learning about the variety of techniques used by banking Trojans can help us detect other activities of financially motivated threat groups. --------------------------------------------- https://unit42.paloaltonetworks.com/banking-trojan-techniques/ ∗∗∗ Follina Exploit Leads to Domain Compromise ∗∗∗ --------------------------------------------- In early June 2022, we observed an intrusion where a threat actor gained initial access by exploiting the CVE-2022-30190 (Follina) vulnerability which triggered a Qbot infection chain. --------------------------------------------- https://thedfirreport.com/2022/10/31/follina-exploit-leads-to-domain-compro… ∗∗∗ Vulnerabilities in Apache Batik Default Security Controls – SSRF and RCE Through Remote Class Loading ∗∗∗ --------------------------------------------- I stumbled upon the Apache Batik library while researching other Java-based products. It immediately caught my attention, as this library parses Scalable Vector Graphics (SVG) files and transforms them into different raster graphics formats (i.e., PNG, PDF, or JPEG). I was even more encouraged when I looked at the Batik documentation. It was obvious that such a library could be prone to Server-Side Request Forgery (SSRF) issues (e.g., loading of images from remote resources). --------------------------------------------- https://www.thezdi.com/blog/2022/10/28/vulnerabilities-in-apache-batik-defa… ∗∗∗ AgentTesla Being Distributed via VBS ∗∗∗ --------------------------------------------- The ASEC analysis team has recently identified that AgentTesla is being distributed through malicious VBS. The script file has multiple codes that have been obfuscated multiple times. AgentTesla has been found to be distributed last May through a Windows Help file (*.chm), and it seems that its distribution method is continuously changing. --------------------------------------------- https://asec.ahnlab.com/en/40890/ ===================== = Vulnerabilities = ===================== ∗∗∗ IBM Security Bulletins ∗∗∗ --------------------------------------------- App Connect Professional, IBM Business Automation Manager Open Editions 8.0.1, IBM CICS TX Advanced, IBM CICS TX Standard, IBM Cloud Pak for Business Automation, IBM Cloud Pak for Security, IBM Event Streams, IBM Host Access Transformation Services, IBM MQ Appliance --------------------------------------------- https://www.ibm.com/blogs/psirt/ ∗∗∗ CVE-2022-31690: Privilege Escalation in spring-security-oauth2-client ∗∗∗ --------------------------------------------- Spring Security 5.6.9 and 5.7.5 released on October 31st, 2022 included a fix for CVE-2022-31690 affecting the mapping of authorized scopes in spring-security-oauth2-client.
