===================== = End-of-Day report = ===================== Timeframe: Dienstag 01-09-2020 18:00 − Mittwoch 02-09-2020 18:00 Handler: Thomas Pribitzer Co-Handler: Stephan Richter ===================== = News = ===================== ∗∗∗ Attackers abuse Google DNS over HTTPS to download malware ∗∗∗ --------------------------------------------- More details have emerged on a malware sample that uses Google DNS over HTTPS to retrieve the stage 2 malicious payload. --------------------------------------------- https://www.bleepingcomputer.com/news/security/attackers-abuse-google-dns-o… ∗∗∗ Exposed Windows Domain Controllers Used in CLDAP DDoS Attacks, (Tue, Sep 1st) ∗∗∗ --------------------------------------------- LDAP, like many UDP based protocols, has the ability to send responses that are larger than the request. With UDP not requiring any handshake before data is sent, these protocols make ideal amplifiers for reflective distributed denial of service attacks. Most commonly, these attacks abuse DNS and we have talked about this in the past. But LDAP is another protocol that is often abused. --------------------------------------------- https://isc.sans.edu/diary/rss/26526 ∗∗∗ Using assert() to Execute Malware in PHP 7 Environments ∗∗∗ --------------------------------------------- Initially released December 2015, PHP 7 introduced a multitude of performance and security improvements. Approximately 43.7% of websites across the web currently use PHP 7.x, making it an incredibly popular scripting language — which is likely why attackers are creating malware to target environments which leverage it. During a recent investigation, our team stumbled across some malicious code which is used to inject a .user.ini file into a PHP 7 environment and add zend.assertions = 1. --------------------------------------------- https://blog.sucuri.net/2020/09/using-assert-to-execute-malware-php-7.html ∗∗∗ Cloud firewall management API SNAFU put 500k SonicWall customers at risk ∗∗∗ --------------------------------------------- TL;DR I found an IDOR in SonicWall’s cloud management platform API Any user could add themselves to any account at any organisation using it Anyone could create a user account [...] --------------------------------------------- https://www.pentestpartners.com/security-blog/cloud-firewall-management-api… ∗∗∗ Erpressungs-Mail mit Bombendrohung massenhaft versendet ∗∗∗ --------------------------------------------- Vorsicht vor einer betrügerischen Erpressungs-E-Mail: Kriminelle versenden Nachrichten, in denen sie behaupten, dass eine Bombe im Geschäftsgebäude der EmpfängerInnen platziert wurde. Sollten die Unternehmen, die die Nachrichten erhalten haben, nicht binnen 80 Stunden 20.000 Dollar in Bitcoin bezahlen, soll diese explodieren.

For the fifth quarter in a row, Cisco Talos Incident Response (CTIR) observed ransomware dominating the threat landscape. Infections involved a wide variety of malware families including Ryuk, Maze, LockBit, and Netwalker, among others. In a continuation of trends observed in last quarter’s report, these ransomware attacks have relied much less on commodity trojans such as Emotet and Trickbot. --------------------------------------------- https://blog.talosintelligence.com/2020/09/CTIR-quarterly-trends-Q4-2020.ht… ∗∗∗ Gratis iPhone 11 oder Samsung Galaxy S20 durch Hofer-Umfrage? ∗∗∗ --------------------------------------------- Kriminelle geben sich als Hofer aus und versenden wahllos E-Mails, in denen behauptet wird, Ihre E-Mail- bzw.
