The San Francisco-based firm blamed a Google Account cloud synchronization feature recently introduced in April 2023 for making the breach worse, calling it a "dark pattern." "The fact that Google Authenticator syncs to the cloud is a novel attack vector," Snir Kodesh, Retool's head of engineering, said. "What we had originally implemented was multi-factor authentication. But through this Google update, what was previously multi-factor-authentication had silently (to administrators) become single-factor-authentication." --------------------------------------------- https://thehackernews.com/2023/09/retool-falls-victim-to-sms-based.html ∗∗∗ Fuzzing with multiple servers in parallel: AFL++ with Network File Systems ∗∗∗ --------------------------------------------- When fuzzing large-scale applications, using a single server (even with 4 64-core AMD Ryzen CPUs) may not be powerful enough by itself. That’s where parallelized/distributed fuzzing comes in (i.e. automatic sharing of results between fuzzing systems). In this guide, we’ll take a look at how to set up multiple servers fuzzing the same program using AFL++, linked all together with an NFS (Network File System). --------------------------------------------- https://joshua.hu/fuzzing-multiple-servers-parallel-aflplusplus-nfs ∗∗∗ donut-decryptor ∗∗∗ --------------------------------------------- donut-decryptor checks file(s) for known signatures of the donut obfuscators loader shellcode. If located, it will parse the shellcode to locate, decrypt, and extract the DONUT_INSTANCE structure embedded in the binary, and report pertinent configuration data. If a DONUT_MODULE is present in the binary it is decrypted and dumped to disk. --------------------------------------------- https://github.com/volexity/donut-decryptor ∗∗∗ CVE-2023-34040 Spring Kafka Deserialization Remote Code Execution ∗∗∗ --------------------------------------------- MEDIUM | AUGUST 23, 2023 | CVE-2023-34040: In Spring for Apache Kafka 3.0.9 and earlier and versions 2.9.10 and earlier, a possible deserialization attack vector existed, but only if unusual configuration was applied. An attacker would have to construct a malicious serialized object in one of the deserialization exception record headers [...] According to the description in security bulletin, we can simply attain some critical points resulting in the vulnerability. --------------------------------------------- https://pyn3rd.github.io/2023/09/15/CVE-2023-34040-Spring-Kafka-Deserializa… ∗∗∗ AWS’s Hidden Threat: AMBERSQUID Cloud-Native Cryptojacking Operation ∗∗∗ --------------------------------------------- The Sysdig Threat Research Team (TRT) has uncovered a novel cloud-native cryptojacking operation which they’ve named AMBERSQUID. This operation leverages AWS services not commonly used by attackers, such as AWS Amplify, AWS Fargate, and Amazon SageMaker. The uncommon nature of these services means that they are often overlooked from a security perspective, and the AMBERSQUID operation can cost victims more than $10,000/day. --------------------------------------------- https://sysdig.com/blog/ambersquid/ ∗∗∗ Fileless Remote Code Execution on Juniper Firewalls ∗∗∗ --------------------------------------------- CVE-2023-36845 is a PHP environment variable manipulation vulnerability affecting Juniper SRX firewalls and EX switches.

At the time it was blamed on faulty flight data, but news now emerges that the data which brought down an entire country’s air traffic control may have not been faulty at all. --------------------------------------------- https://hackaday.com/2023/09/13/how-three-letters-brought-down-uk-air-traff… ∗∗∗ 3AM: New Ransomware Family Used As Fallback in Failed LockBit Attack ∗∗∗ --------------------------------------------- Attackers resorted to new ransomware after deployment of LockBit was blocked on targeted network. --------------------------------------------- https://symantec-enterprise-blogs.security.com/threat-intelligence/3am-rans… ∗∗∗ White House urging dozens of countries to publicly commit to not pay ransoms ∗∗∗ --------------------------------------------- The U.S. National Security Council (NSC) is urging the governments of all countries participating in the International Counter Ransomware Initiative (CRI) to issue a joint statement announcing they will not pay ransoms to cybercriminals, according to three sources with knowledge of the plans. --------------------------------------------- https://therecord.media/counter-ransomware-initiative-members-ransom-paymen… ∗∗∗ September 2023 release of new Exchange Server CVEs (resolved by August 2023 Security Updates) ∗∗∗ --------------------------------------------- You may have noticed there were several new Exchange Server CVEs that were released today (a part of September 2023 ‘Patch Tuesday’). If you haven’t yet, you can go to the Security Update Guide and filter on Exchange Server under Product Family to review CVE information. The CVEs released today were actually addressed in the August 2023 Exchange Server Security Update (SU). Due to the timing of validation of those fixes and release dates, we decided to release the CVEs as a part of September 2023 ‘Patch Tuesday’ release cycle. We know that many customers are accustomed to checking for Microsoft security releases on the second Tuesday of every month, and we did not want these CVEs to go unnoticed. --------------------------------------------- https://techcommunity.microsoft.com/t5/exchange-team-blog/september-2023-re… ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Wednesday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (e2guardian), Fedora (libeconf), Red Hat (dmidecode, kernel, kernel-rt, keylime, kpatch-patch, libcap, librsvg2, linux-firmware, and qemu-kvm), Slackware (mozilla), SUSE (chromium and shadow), and Ubuntu (cups, dotnet6, dotnet7, file, flac, and ruby-redcloth). --------------------------------------------- https://lwn.net/Articles/944354/ ∗∗∗ BSRT-2023-001 Vulnerabilities in Management Console and Self Service Impact AtHoc Server ∗∗∗ --------------------------------------------- https://support.blackberry.com/kb/articleDetail?language=en_US&articleNumbe… ∗∗∗ VU#347067: Multiple BGP implementations are vulnerable to improperly formatted BGP updates ∗∗∗ --------------------------------------------- https://kb.cert.org/vuls/id/347067 ∗∗∗ PHP Shopping Cart-4.2 Multiple-SQLi ∗∗∗ --------------------------------------------- https://cxsecurity.com/issue/WLB-2023090037 ∗∗∗ Cisco IOS XR Software Compression ACL Bypass Vulnerability ∗∗∗ --------------------------------------------- https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdviso… ∗∗∗ Cisco IOS XR Software Image Verification Vulnerability ∗∗∗ --------------------------------------------- https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdviso… ∗∗∗ Cisco IOS XR Software iPXE Boot Signature Bypass Vulnerability ∗∗∗ --------------------------------------------- https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdviso… ∗∗∗ Cisco IOS XR Software Model-Driven Programmability Behavior with AAA Authorization ∗∗∗ --------------------------------------------- https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdviso… ∗∗∗ Cisco IOS XR Software Connectivity Fault Management Denial of Service Vulnerability ∗∗∗ --------------------------------------------- https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdviso… ∗∗∗ Cisco IOS XR Software Access Control List Bypass Vulnerability ∗∗∗ --------------------------------------------- https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdviso… ∗∗∗ IBM Security Bulletins ∗∗∗ --------------------------------------------- https://www.ibm.com/support/pages/bulletin/ ∗∗∗ K000136157 : sssd vulnerability CVE-2022-4254 ∗∗∗ --------------------------------------------- https://my.f5.com/manage/s/article/K000136157?utm_source=f5support&utm_medi… ∗∗∗ Trumpf: Multiple Products affected by WIBU Codemeter Vulnerability ∗∗∗ --------------------------------------------- https://cert.vde.com/de/advisories/VDE-2023-031/ ∗∗∗ Elliptic Labs Virtual Lock Sensor Vulnerability ∗∗∗ --------------------------------------------- https://support.lenovo.com/product_security/PS500576-ELLIPTIC-LABS-VIRTUAL-… ∗∗∗ Lenovo XClarity Controller (XCC) Vulnerabilities ∗∗∗ --------------------------------------------- https://support.lenovo.com/product_security/PS500578 ∗∗∗ Intel Dynamic Tuning Technology Advisory ∗∗∗ --------------------------------------------- https://support.lenovo.com/product_security/PS500577-INTEL-DYNAMIC-TUNING-T… -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

Unfortunately, the same precautions were not implemented on the /404 page or any /nonexistingurl. We discovered that the response for any endpoint that doesnt exist contained PII information without any cache controls in place. --------------------------------------------- https://blog.agilehunt.com/blogs/security/web-cache-deception-attack-on-404… ∗∗∗ Whats in a name? [..] The .kids TLD is not alright ∗∗∗ --------------------------------------------- Cisco Talos successfully registered the domain name: your-dns-needs-immediate-attention.kids. Talos set up an internet server to log all activity related to this name, and immediately we received a barrage of HTTP requests from systems running Microsoft’s “System Center Configuration Manager.” [..] we were able to masquerade as a trusted system. Networks using .kids names could be tricked into trusting our system to relay internal mail, dictate configuration management settings, and more. --------------------------------------------- https://blog.talosintelligence.com/whats-in-a-name/ ∗∗∗ Inconsistencies in the Common Vulnerability Scoring System (CVSS) ∗∗∗ --------------------------------------------- The goal of CVSS is to provide comparable scores across different evaluators. However, previous works indicate that CVSS might not reach this goal: If a vulnerability is evaluated by several analysts, their scores often differ. This raises the following questions: Are CVSS evaluations consistent? Which factors influence CVSS assessments? We systematically investigate these questions in an online survey with 196 CVSS users. --------------------------------------------- https://www.schneier.com/blog/archives/2023/09/inconsistencies-in-the-commo… ∗∗∗ CVE-2023-4634 - Tricky Unauthenticated RCE on Wordpress Media Library Assistant Plugin using a good old Imagick ∗∗∗ --------------------------------------------- As discussed in many of our articles, you already know that WordPress and related plugins are taking up a large space in the global attack surface [..] The vulnerability described below is a perfect example --------------------------------------------- https://patrowl.io/blog-wordpress-media-library-rce-cve-2023-4634/ ∗∗∗ When URL parsers disagree (CVE-2023-38633) ∗∗∗ --------------------------------------------- Discovery and walkthrough of CVE-2023-38633 in librsvg, when two URL parser implementations (Rust and Glib) disagree on file scheme parsing leading to path traversal. --------------------------------------------- https://www.canva.dev/blog/engineering/when-url-parsers-disagree-cve-2023-3… ∗∗∗ Vorsicht vor betrügerischen PayPal-Anrufen ∗∗∗ --------------------------------------------- Ihr Telefon klingelt.

Publicly accessible MS-SQL servers with simple passwords are one of the main attack vectors used when targeting Windows systems. Typically, threat actors target poorly managed MS-SQL servers and attempt to gain access through brute force or dictionary attacks. If successful, they install malware on the infected system. --------------------------------------------- https://asec.ahnlab.com/en/56350/ ∗∗∗ Stories from the SOC - Unveiling the stealthy tactics of Aukill malware ∗∗∗ --------------------------------------------- On April 21st, 2023, AT&T Managed Extended Detection and Response (Managed XDR) investigated an attempted ransomware attack on one of our clients, a home improvement business.

According to the Symantec Threat Hunter Team, part of Broadcom, the development is an attempt on the part of the e-crime group to diversify its focus and maximize profits from infected entities. --------------------------------------------- https://thehackernews.com/2023/07/fin8-group-using-modified-sardonic.html ∗∗∗ Uncovering drIBAN fraud operations.

Then, we discovered that sLoad is a dropper for Ramnit [..] After that, we also described Ramnit’s capabilities, focusing mainly on its injection and persistence techniques. As a final step, we will discuss drIBAN, a sophisticated and modular web-inject kit that can hide resources, masquerade its presence, and perform large-scale ATS attacks. --------------------------------------------- https://www.cleafy.com/cleafy-labs/uncovering-driban-fraud-operations-chapt… ∗∗∗ Wordpress: Angriffswelle auf Woocommerce Payments läuft derzeit ∗∗∗ --------------------------------------------- Die IT-Forscher von Wordfence beobachten eine Angriffswelle auf das Woocommerce Payments-Plug-in.

[..] Orca Security immediately reported the findings to the Google Security Team, who investigated the issue and deployed a partial fix. However, Google’s fix doesn’t revoke the discovered Privilege Escalation (PE) vector.

===================== = End-of-Day report = ===================== Timeframe: Freitag 16-06-2023 18:00 − Montag 19-06-2023 18:00 Handler: Robert Waldner Co-Handler: Stephan Richter ===================== = News = ===================== ∗∗∗ Android spyware camouflaged as VPN, chat apps on Google Play ∗∗∗ --------------------------------------------- Three Android apps on Google Play were used by state-sponsored threat actors to collect intelligence from targeted devices, such as location data and contact lists. --------------------------------------------- https://www.bleepingcomputer.com/news/security/android-spyware-camouflaged-… ∗∗∗ Security Expert Defeats Lenovo Laptop BIOS Password With a Screwdriver ∗∗∗ --------------------------------------------- Cybersecurity experts at CyberCX have demonstrated a simple method for consistently accessing older BIOS-locked laptops by shorting pins on the EEPROM chip with a screwdriver, enabling full access to the BIOS settings and bypassing the password. --------------------------------------------- https://it.slashdot.org/story/23/06/16/2322255/security-expert-defeats-leno… ∗∗∗ From Cryptojacking to DDoS Attacks: Diicot Expands Tactics with Cayosin Botnet ∗∗∗ --------------------------------------------- Cybersecurity researchers have discovered previously undocumented payloads associated with a Romanian threat actor named Diicot, revealing its potential for launching distributed denial-of-service (DDoS) attacks. "The Diicot name is significant, as its also the name of the Romanian organized crime and anti-terrorism policing unit," Cado Security said in a technical report. --------------------------------------------- https://thehackernews.com/2023/06/from-cryptojacking-to-ddos-attacks.html ∗∗∗ New Mystic Stealer Malware Targets 40 Web Browsers and 70 Browser Extensions ∗∗∗ --------------------------------------------- A new information-stealing malware called Mystic Stealer has been found to steal data from about 40 different web browsers and over 70 web browser extensions. First advertised on April 25, 2023, for $150 per month, the malware also targets cryptocurrency wallets, Steam, and Telegram, and employs extensive mechanisms to resist analysis. --------------------------------------------- https://thehackernews.com/2023/06/new-mystic-stealer-malware-targets-40.html ∗∗∗ [SANS ISC] Malware Delivered Through .inf File ∗∗∗ --------------------------------------------- Today, I published the following diary on isc.sans.edu: “Malware Delivered Through .inf File“: Microsoft has used “.inf” files for a while. They are simple text files and contain setup information in a driver package. They describe what must be performed to install a driver package on a device. When you read them, the syntax is straightforward to understand. The file is based on sections that describe what must be performed. One of them is very interesting for attackers: [RunPreSetupCommandsSection]. --------------------------------------------- https://blog.rootshell.be/2023/06/19/sans-isc-malware-delivered-through-inf… ∗∗∗ The Phantom Menace: Exposing hidden risks through ACLs in Active Directory (Part 1) ∗∗∗ --------------------------------------------- The abuse of misconfigured Access Control Lists is nothing new. However, it is still one of the main ways of lateral movement and privilege escalation within an active directory domain. [..] In this post, we will discuss, in a general overview, some concepts that will help us understand how Windows handles access relationships and privileges between objects and how to enumerate these relationships. --------------------------------------------- https://labs.lares.com/securing-active-directory-via-acls/ ∗∗∗ Speculative Denial-of-Service Attacks in Ethereum ∗∗∗ --------------------------------------------- Block proposers speculatively execute transactions when creating blocks to maximize their profits. How can this go wrong? In “Speculative Denial-of-Service Attacks in Ethereum”, we show how speculative execution allows attackers to cheaply DoS the network. --------------------------------------------- https://medium.com/@aviv.yaish/speculative-denial-of-service-attacks-in-eth… ∗∗∗ Warning: Malware Disguised as a Security Update Installer Being Distributed ∗∗∗ --------------------------------------------- AhnLab, in collaboration with the National Cyber Security Center (NCSC) Joint Analysis and Consultation Council, has recently uncovered the attack of a hacking group that is supported by a certain government. The discovered malware disguised itself as a security update installer and was developed using the Inno Setup software. --------------------------------------------- https://asec.ahnlab.com/en/54375/ ===================== = Vulnerabilities = ===================== ∗∗∗ ZDI-23-889: Schneider Electric IGSS DashFiles Deserialization of Untrusted Data Remote Code Execution Vulnerability ∗∗∗ --------------------------------------------- This vulnerability allows remote attackers to execute arbitrary code on affected installations of Schneider Electric IGSS. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. ---------------------------------------------

That means we purchase bug reports from independent security researchers around the world in Microsoft applications, Adobe, Cisco, Apple, IBM, Dell, Trend Micro, SCADA systems, etc. We don’t buy every bug report submitted, but we buy a lot of bugs.
