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).

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.

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.

Phishing, in general, has grown in scale and sophistication in recent years, with the most damaging form of phishing from a financial perspective being “business email compromise” (BEC). According to Check Point Research, credential harvesting makes up about 15% of all email-based attacks but is the most financially damaging category. --------------------------------------------- https://blog.checkpoint.com/security/how-companies-can-get-a-grip-on-busine… ===================== = Vulnerabilities = ===================== ∗∗∗ Multiple vulnerabilities in i-PRO VI Web Client ∗∗∗ --------------------------------------------- VI Web Client provided by i-PRO Co., Ltd. contains multiple vulnerabilities.
