But if you have the game installed and haven’t updated it, it’s important to either update or uninstall it as soon as possible. Keep in mind this exploit is possible even if you haven’t got an active iRacing subscription, so if you were thinking about updating it later, it’s worth uninstalling it in the meanwhile. --------------------------------------------- https://blog.ss23.geek.nz/2023/09/21/iracing-electron-rce-exploit.html ∗∗∗ Außergewöhnliche Malware nimmt westeuropäische Telkos ins Visier ∗∗∗ --------------------------------------------- Lua Dream ist ein mittels Lua modular aufgebauter Schädling, der es auf Telekommunikationsunternehmen abgesehen hat – und wahrscheinlich aus Asien stammt. --------------------------------------------- https://www.heise.de/-9315204.html ∗∗∗ In-the-Wild Exploitation Expected for Critical TeamCity Flaw Allowing Server Takeover ∗∗∗ --------------------------------------------- A critical vulnerability in the TeamCity CI/CD server could allow unauthenticated attackers to execute code and take over vulnerable servers. --------------------------------------------- https://www.securityweek.com/in-the-wild-exploitation-expected-for-critical… ∗∗∗ Webinar: Manipulation durch Dark Patterns – wie kann ich mich schützen? ∗∗∗ --------------------------------------------- Dark Patterns werden im Internet eingesetzt, um uns zu Handlungen zu verleiten, die nicht in unserem Interesse liegen – und so z.

When an administrative user is granted a security role in SCCM, such as Full Administrator or Infrastructure Administrator, in any primary site, the underlying database changes propagate upward to the central administration site (CAS) and then to other primary sites in the hierarchy. This means that if an attacker gains control of any primary site, they gain control of the entire SCCM hierarchy. --------------------------------------------- https://posts.specterops.io/sccm-hierarchy-takeover-41929c61e087 ∗∗∗ iOS 17 update secretly changed your privacy settings; here’s how to set them back ∗∗∗ --------------------------------------------- Many iPhone users who upgraded their iPhones to the recently-released iOS 17 will be alarmed to hear that they may have actually downgraded their security and privacy. --------------------------------------------- https://www.bitdefender.com/blog/hotforsecurity/ios-17-update-secretly-chan… ∗∗∗ From ScreenConnect to Hive Ransomware in 61 hours ∗∗∗ --------------------------------------------- In 2022, The DFIR Report observed an increase in the adversarial usage of Remote Management and Monitoring (RMM) tools.

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 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.
