However, in the IT world, it is not shortages or pandemics that have been the main obstacles to overcome in recent years, but rather attacks aimed at using them to harm hundreds or even thousands of victims simultaneously. --------------------------------------------- https://thehackernews.com/2022/10/how-software-supply-chain-security-is.html ∗∗∗ Researchers Detail Windows Event Log Vulnerabilities: LogCrusher and OverLog ∗∗∗ --------------------------------------------- Cybersecurity researchers have disclosed details about a pair of vulnerabilities in Microsoft Windows, one of which could be exploited to result in a denial-of-service (DoS). --------------------------------------------- https://thehackernews.com/2022/10/researchers-detail-windows-event-log.html ∗∗∗ Chapter 1 - From Gozi to ISFB: The history of a mythical malware family. ∗∗∗ --------------------------------------------- Disclaimer: This article does not contain any IOCs or infrastructure details. Instead, the aim is to explain the whole business dynamic of a long-lasting malware family. This work is based on almost 10 years of research and intel gatherings and tries its best to stick to the truth and the facts observed around ISFB. Hopefully, it will give some insight on how the top cyber crime groups have been working over the years. --------------------------------------------- https://medium.com/csis-techblog/chapter-1-from-gozi-to-isfb-the-history-of… ∗∗∗ Stranger Strings: An exploitable flaw in SQLite ∗∗∗ --------------------------------------------- Trail of Bits is publicly disclosing CVE-2022-35737, which affects applications that use the SQLite library API. CVE-2022-35737 was introduced in SQLite version 1.0.12 (released on October 17, 2000) and fixed in release 3.39.2 (released on July 21, 2022).

From changing its file extension, injection and to UAC bypassing techniques, the Magniber ransomware has been rapidly changing to bypass the detection of anti-malware software. This article summarizes the evolution of the Magniber ransomware in the last few months based on the analysis that had been previously performed. --------------------------------------------- https://asec.ahnlab.com/en/40422/ ∗∗∗ Analysis on Attack Techniques and Cases Using RDP ∗∗∗ --------------------------------------------- Overview One of the previous ASEC blog posts discussed cases where attackers abused various remote control tools that are originally used for system management purposes to gain control over infected systems.

To the point that my tool rtfdump.py and Philippe's tool rtfobj don't find embedded objects. --------------------------------------------- https://isc.sans.edu/diary/rss/29174 ∗∗∗ C2 Communications Through outlook.com, (Mon, Oct 24th) ∗∗∗ --------------------------------------------- Most malware implements communication with their C2 server over HTTP(S). Why? Just because it works! But they are multiple ways to implement C2 communications: DNS, P2P, Layer 7 (Twitter), ... Another one that has become less popular with time is SMTP (email communications). I spotted a malicious Python script that exchanges information with its C2 server through emails. --------------------------------------------- https://isc.sans.edu/diary/rss/29180 ∗∗∗ SCuBA M365 Security Baseline Assessment Tool ∗∗∗ --------------------------------------------- Developed by CISA, this assessment tool verifies that an M365 tenant’s configuration conforms to the policies described in the SCuBA Minimum Viable Secure Configuration Baseline documents. --------------------------------------------- https://github.com/cisagov/ScubaGear ∗∗∗ Cisco ISE: Angreifer könnten Kontrolle übernehmen ∗∗∗ --------------------------------------------- Cisco warnt, dass Angreifer Dateien in der Identity Services Engine lesen und löschen könnten.

The way it works is that a “Key Scheduling Algorithm” (KSA) takes your key and generates a 256-byte array, and then a “Pseudo-Random Generation Algorithm” (PRGA) uses that byte array to output an endless stream of bytes (the “key stream”), which look like random noise unless you know what the original byte array was. --------------------------------------------- https://research.checkpoint.com/2022/attacking-very-weak-rc4-like-ciphers-t… ∗∗∗ Uncovering Security Blind Spots in CNC Machines ∗∗∗ --------------------------------------------- Industry 4.0 has given rise to smart factories that have markedly improved machining processes, but it has also opened the doors for cybercriminals looking to abuse networked industrial equipment such as CNC machines.

Updates stehen bereit. --------------------------------------------- https://heise.de/-7316039 ∗∗∗ Gefahren für kritische Infrastrukturen: "Uns fehlt eine Schwachstellenanalyse" ∗∗∗ --------------------------------------------- Prof. Norbert Gebbeken, Gründer und Sprecher des Forschungszentrums RISK, über die Gefahren, die unserer kritischen Infrastruktur drohen – und was man tun kann. --------------------------------------------- https://heise.de/-7315119 ∗∗∗ Your Microsoft Exchange Server Is a Security Liability ∗∗∗ --------------------------------------------- Endless vulnerabilities. Massive hacking campaigns. Slow and technically tough patching. Its time to say goodbye to on-premise Exchange. --------------------------------------------- https://www.wired.com/story/microsoft-exchange-server-vulnerabilities/ ∗∗∗ sczriptzzbn inject pushes malware for NetSupport RAT, (Fri, Oct 21st) ∗∗∗ --------------------------------------------- A campaign nicknamed "sczriptzzbn inject" can be identified by script using a variable named sczriptzzbn injected into files returned from a compromised website. This injected script causes a fake browser update page to appear in the victim's browser. The fake browser update page presents the malware payload for download. More information on the campaign can be found here. In previous weeks, this campaign pushed SolarMarker malware. I ran across one such example on 2022-09-27. This month, we've started seeing a payload for NetSupport RAT from the sczriptzzbn inject. --------------------------------------------- https://isc.sans.edu/diary/rss/29170 ∗∗∗ Archive Sidestepping: Emotet Botnet Pushing Self-Unlocking Password-Protected RAR ∗∗∗ --------------------------------------------- Trustwave SpiderLabs’ spam traps have identified an increase in threats packaged in password-protected archives with about 96% of these being spammed by the Emotet Botnet. In the first half of 2022, we identified password-protected ZIP files as the third most popular archive format used by cybercriminals to conceal malware. --------------------------------------------- https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/archive-sid… ∗∗∗ Wordfence Evasion Malware Conceals Backdoors ∗∗∗ --------------------------------------------- Malware authors, with some notable exceptions, tend to design their malicious code to hide from sight.

However, initial analysis indicates that this is a bad comparison. The nature of the vulnerability means that unlike Log4Shell, it will be rare that an application uses the vulnerable component of Commons Text to process untrusted, potentially malicious input. In summary, much like with Spring4Shell, there are significant caveats to practical exploitability for CVE-2022-42889. With that said, we still recommend patching any relevant impacted software according to your normal, hair-not-on-fire patch cycle. --------------------------------------------- https://www.rapid7.com/blog/post/2022/10/17/cve-2022-42889-keep-calm-and-st… ∗∗∗ Europol: Festgenommene Autodiebe stahlen Fahrzeuge mittels Software ∗∗∗ --------------------------------------------- In Frankreich wurden 31 Mitglieder einer Diebesbande festgenommen, die Autos mit schlüssellosen Zugangssystemen per Software gestohlen haben sollen. --------------------------------------------- https://www.golem.de/news/europol-festgenommene-autodiebe-stahlen-fahrzeuge… ∗∗∗ Sicherheit: Antivirensoftware blockiert Thunderbird-Updates ∗∗∗ --------------------------------------------- Statt für Sicherheit zu sorgen, blockieren Avast und AVG Thunderbird-Updates.

Rapid7 investigated these issues to better understand their impact, and found that the patch is not sufficient to prevent exploitation. We also determined that the worst outcome of this vulnerability is a denial of service - the licensing server can be told to shut down (even with the patch). --------------------------------------------- https://www.rapid7.com/blog/post/2022/10/18/flexlm-and-citrix-adm-denial-of… ∗∗∗ Python Obfuscation for Dummies, (Tue, Oct 18th) ∗∗∗ --------------------------------------------- Recently, I found several malicious Python scripts that looked the same.
