It helps to record all activities performed by a script and is a goldmine for incident handlers. That's the reason why attackers tend to try to disable this feature. There are many ways to achieve this, but I found an interesting one. --------------------------------------------- https://isc.sans.edu/diary/rss/29538 ∗∗∗ Bogus URL Shorteners Redirect Thousands of Hacked Sites in AdSense Fraud Campaign ∗∗∗ --------------------------------------------- Late last year we reported on a malware campaign targeting thousands of WordPress websites to redirect visitors to bogus Q&A websites. The sites themselves contained very little useful information to a regular visitor, but — more importantly — also contained Google Adsense advertisements. It appeared to be an attempt to artificially pump ad views to generate revenue.

RSMBI connect to each target and it mounts the available shares in the /tmp folder (but that can also be changed). Once the shares are successfully mounted the threads (or the solo one) would start (os.)walking recursively all the folders, trying get a file handle with writing rights. --------------------------------------------- https://github.com/oldboy21/RSMBI ∗∗∗ 0Day Avalanche Blockchain API DoS ∗∗∗ --------------------------------------------- This is a remote API DoS/crash that should OOM chain P and render a vulnerable node mostly or entirely useless. --------------------------------------------- https://g.livejournal.com/15852.html ∗∗∗ Fake-Spendenaufrufe: Kriminelle missbrauchen Erdbebenkatastrophe ∗∗∗ --------------------------------------------- Das Erdbeben in der Türkei und in Nordsyrien löste eine Welle der Hilfsbereitschaft aus.

===================== = End-of-Day report = ===================== Timeframe: Mittwoch 08-02-2023 18:00 − Donnerstag 09-02-2023 18:00 Handler: Robert Waldner Co-Handler: n/a ===================== = News = ===================== ∗∗∗ New ESXiArgs ransomware version prevents VMware ESXi recovery ∗∗∗ --------------------------------------------- New ESXiArgs ransomware attacks are now encrypting more extensive amounts of data, making it much harder, if not impossible, to recover encrypted VMware ESXi virtual machines. --------------------------------------------- https://www.bleepingcomputer.com/news/security/new-esxiargs-ransomware-vers… ∗∗∗ Solving one of NOBELIUM’s most novel attacks: Cyberattack Series ∗∗∗ --------------------------------------------- This is the first in an ongoing series exploring some of the most notable cases of the Microsoft Detection and Response Team (DART), which investigates cyberattacks on behalf of our customers. The Cyberattack Series takes you behind the scenes for an inside look at the investigation and share lessons that you can apply to better protect your own organization. --------------------------------------------- https://www.microsoft.com/en-us/security/blog/2023/02/08/solving-one-of-nob… ∗∗∗ [SANS ISC] A Backdoor with Smart Screenshot Capability ∗∗∗ --------------------------------------------- Today, everything is “smart” or “intelligent”. We have smartphones, smart cars, smart doorbells, etc. Being “smart” means performing actions depending on the context, the environment, or user actions. For a while, backdoors and trojans have implemented screenshot capabilities. From an attacker’s point of view, it’s interesting to “see” what’s displayed on the victim’s computer. --------------------------------------------- https://blog.rootshell.be/2023/02/09/sans-isc-a-backdoor-with-smart-screens… ∗∗∗ Exploit Vector Analysis of Emerging ESXiArgs Ransomware ∗∗∗ --------------------------------------------- In recent days CVE-2021-21974, a heap-overflow vulnerability in VMWare ESXi’s OpenSLP service has been prominently mentioned in the news in relation to a wave of ransomware effecting numerous organizations. The relationship between CVE-2021-21974 and the ransomware campaign may be blown out of proportion. We do not currently know what the initial access vector is, and it is possible it could be any of the vulnerabilities related to ESXi’s OpenSLP service. --------------------------------------------- https://www.greynoise.io/blog/exploit-vector-analysis-of-emerging-esxiargs-… ∗∗∗ Passwort-Manager: Umstrittene Sicherheitslücke in KeePass beseitigt ∗∗∗ --------------------------------------------- Eine viel diskutierte Sicherheitslücke, die Einbrechern im System den Passwort-Export erleichterte, hat der Entwickler nun mit einem Update geschlossen. --------------------------------------------- https://heise.de/-7489944 ∗∗∗ Datenleck: Deezer informiert Kunden jetzt per E-Mail ∗∗∗ --------------------------------------------- 230 Millionen Deezer-Datensätze wurden entwendet und etwa beim Have-I-been-pwned-Projekt hinzugefügt.

Bei einer Internetrecherche stoßen Sie möglicherweise auf asia-visa.com – ein Anbieter, der Ihnen den „Papierkram“ abnimmt. Wir raten Ihnen ab, das überteuerte Angebot zu nutzen und empfehlen, die Einreisegenehmigung über die offizielle Stelle zu beantragen. --------------------------------------------- https://www.watchlist-internet.at/news/teures-visum-bei-asia-visacom/ ∗∗∗ CISA and FBI Release ESXiArgs Ransomware Recovery Guidance ∗∗∗ --------------------------------------------- Today, CISA and the Federal Bureau of Investigation (FBI) released a joint Cybersecurity Advisory, ESXiArgs Ransomware Virtual Machine Recovery Guidance. This advisory describes the ongoing ransomware campaign known as “ESXiArgs.” Malicious cyber actors may be exploiting known vulnerabilities in unpatched and out-of-service or out-of-date versions of VMware ESXi software to gain access to ESXi servers and deploy ESXiArgs ransomware. --------------------------------------------- https://us-cert.cisa.gov/ncas/current-activity/2023/02/08/cisa-and-fbi-rele… ∗∗∗ Neue PayPal-Betrugsmasche – mit echten Push-Benachrichtigungen (Feb. 2023) ∗∗∗ --------------------------------------------- Über Twitter bin ich auf eine neue Betrugsmasche hingewiesen worden, die Leute schon mal ins Boxhorn jagen kann. Denn die Masche beginnt, dass das Opfer eine Push-Benachrichtigung von PayPal über eine Zahlung (per Einzug) bekommt. Aber die Nachricht ist trotzdem Betrug und hat das Ziel, an Daten des Opfers heranzukommen. Ich habe die Hinweise auf Twitter mal in diesem Beitrag zusammen gefasst. --------------------------------------------- https://www.borncity.com/blog/2023/02/08/neue-paypal-betrugsmasche-mit-echt… ∗∗∗ Sicherheitsvorfall bei wargaming.net (Feb. 2023)? ∗∗∗ --------------------------------------------- Ein Leser hat mich auf einen Sicherheitsvorfall beim Spieleentwickler wargaming.net aufmerksam gemacht. Ich habe dann ein wenig recherchiert, ist nicht der erste Vorfall bei diesem Anbieter. Es könnte aber auch ein Phishing-Versuch sein (das versuche ich noch zu klären). Hier einige Informationen, was mir bekannt ist. --------------------------------------------- https://www.borncity.com/blog/2023/02/09/sicherheitsvorfall-bei-wargaming-n… ∗∗∗ Evasion Techniques Uncovered: An Analysis of APT Methods ∗∗∗ --------------------------------------------- DLL search order hijacking and DLL sideloading are commonly used by nation state sponsored attackers to evade detection. --------------------------------------------- https://www.rapid7.com/blog/post/2023/02/09/evasion-techniques-uncovered-an… ===================== = Vulnerabilities = ===================== ∗∗∗ Zoho ManageEngine ServiceDesk Plus 14003 Remote Code Execution ∗∗∗ --------------------------------------------- This exploits an unauthenticated remote code execution vulnerability that affects Zoho ManageEngine ServiceDesk Plus versions 14003 and below (CVE-2022-47966). Due to a dependency to an outdated library (Apache Santuario version 1.4.1), it is possible to execute arbitrary code by providing a crafted `samlResponse` XML to the ServiceDesk Plus SAML endpoint. Note that the target is only vulnerable if it has been configured with SAML-based SSO at least once in the past, regardless of the current SAML-based SSO status. --------------------------------------------- https://cxsecurity.com/issue/WLB-2023020017 ∗∗∗ SOUND4 LinkAndShare Transmitter 1.1.2 Format String Stack Buffer Overflow ∗∗∗ --------------------------------------------- The application suffers from a format string memory leak and stack buffer overflow vulnerability because it fails to properly sanitize user supplied input when calling the getenv() function from MSVCR120.DLL resulting in a crash overflowing the memory stack and leaking sensitive information. The attacker can abuse the username environment variable to trigger and potentially execute code on the affected system. --------------------------------------------- https://www.zeroscience.mk/en/vulnerabilities/ZSL-2023-5744.php ∗∗∗ Angreifer könnten über Nvidia GeForce Experience Daten manipulieren ∗∗∗ --------------------------------------------- In der aktuellen Version das Grafikkarten-Tools GeForce Experience von Nvidia haben die Entwickler drei Sicherheitslücken geschlossen. --------------------------------------------- https://heise.de/-7490068 ∗∗∗ Notfallpatch für Dateiübertragungslösung GoAnywhere MFT erschienen ∗∗∗ --------------------------------------------- Admins können ihre GoAnywhere-MFT-Server (On-Premises) nun mit einem Sicherheitsupdate gegen aktuelle laufende Attacken absichern. --------------------------------------------- https://heise.de/-7490040 ∗∗∗ Security updates for Thursday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (chromium, libsdl2, and wireshark), Fedora (pesign, tpm2-tss, and webkitgtk), Oracle (hsqldb, krb5, libksba, tigervnc, and tigervnc and xorg-x11-server), Red Hat (openvswitch2.13, openvswitch2.15, openvswitch2.16, openvswitch2.17, rh-varnish6-varnish, tigervnc, and tigervnc and xorg-x11-server), Scientific Linux (tigervnc and xorg-x11-server), and SUSE (apache2, apache2-mod_security2, apr-util, netatalk, podman, python-swift3, rubygem-globalid, syslog-ng, and thunderbird). --------------------------------------------- https://lwn.net/Articles/922756/ ∗∗∗ Vulnerability Allows Hackers to Remotely Tamper With Dahua Security Cameras ∗∗∗ --------------------------------------------- A vulnerability affecting Dahua cameras and video recorders can be exploited by threat actors to modify a device’s system time. [...] Dahua device vulnerabilities may be targeted by DDoS botnets, but in the case of CVE-2022-30564, it would most likely be exploited in highly targeted attacks whose goal is to tamper with evidence, rather than cybercrime operations. The issue was reported to the vendor in the fall of 2022.

In other words, the CONFIG_INIT_STACK_ALL_ZERO build option does nothing for Rust code! Developers must be cautious to avoid shooting themselves in the foot when porting a driver from C to Rust, especially if they previously relied on this config option to mitigate this class of vulnerability.

===================== = End-of-Day report = ===================== Timeframe: Montag 06-02-2023 18:00 − Dienstag 07-02-2023 18:00 Handler: Robert Waldner Co-Handler: n/a ===================== = News = ===================== ∗∗∗ Researcher breaches Toyota supplier portal with info on 14,000 partners ∗∗∗ --------------------------------------------- The issues were responsibly disclosed to Toyota on November 3, 2022, and the Japanese car maker confirmed they had been fixed by November 23, 2022. EatonWorks published a detailed writeup about the discoveries today after 90 days disclosure process had passed. --------------------------------------------- https://www.bleepingcomputer.com/news/security/researcher-breaches-toyota-s… ∗∗∗ APIs Used by Bots to Detect Public IP address, (Mon, Feb 6th) ∗∗∗ --------------------------------------------- Many of the bots I am observing attempt to detect the infected system&#;x26;#;39;s public ("WAN") IP address. Most of these systems are assumed to be behind NAT. To detect the external IP address, these bots use various public APIs. It may be helpful to detect these requests. Many use unique host names. This will make detecting the request in DNS logs easy even if TLS is not intercepted. --------------------------------------------- https://isc.sans.edu/diary/rss/29516 ∗∗∗ Android Security Bulletin—February 2023 ∗∗∗ --------------------------------------------- The Android Security Bulletin contains details of security vulnerabilities affecting Android devices. Security patch levels of 2023-02-05 or later address all of these issues. [..] The most severe of these issues is a high security vulnerability in the Framework component that could lead to local escalation of privilege with no additional execution privileges needed. --------------------------------------------- https://source.android.com/docs/security/bulletin/2023-02-01 ∗∗∗ Discovering a weakness leading to a partial bypass of the login rate limiting in the AWS Console ∗∗∗ --------------------------------------------- AWS applies a rate limit to authentication requests made to the AWS Console, in an effort to prevent brute-force and credential stuffing attacks. In this post, we discuss a weakness we discovered in the AWS Console authentication flow that allowed us to partially bypass this rate limit and continuously attempt more than 280 passwords per minute (4.6 per second). The weakness was since mitigated by AWS. --------------------------------------------- https://securitylabs.datadoghq.com/articles/aws-console-rate-limit-bypass/ ∗∗∗ Smishing: Vorsicht vor Fake Magenta-SMS ∗∗∗ --------------------------------------------- Momentan sind vermehrt gefälschte Magenta-SMS im Umlauf.
