From Egregor to Doppelpaymer to Ryuk, it continues to command headlines. Pandemic-fueled phishing scams, the lack of visibility across remote endpoints, and lax attitudes have been a boon for ransomware groups over the last year. Worst of all, ransomware no longer discriminates. It dominates small towns and municipal offices, video game makers, and shamelessly, healthcare organizations and school systems already pushed to the brink by the COVID-19 pandemic. The threat could still become more pervasive over the next two to three years, not because ransomware is effective in and of itself but because of other players in the game - insurance companies, brokers, and even attorneys - that continue to fan the flames. --------------------------------------------- https://www.securityweek.com/inside-ransomware-economy ∗∗∗ Einreiseanmeldung für Deutschland nicht über „digitale-einreiseanmeldung.de“ vornehmen ∗∗∗ --------------------------------------------- Die Corona-Pandemie erschwert die Einreise in andere Länder erheblich.

These queries inject an admin level user into the infected database whenever the trigger condition is met. What makes this especially problematic for website owners is that most malware cleanup guides focus on the website files and data within specific database tables — for example, wp_users, wp_options, and wp_posts. --------------------------------------------- https://blog.sucuri.net/2021/02/sql-triggers-in-website-backdoors.html ∗∗∗ ALERT: Malicious Amazon Alexa Skills Can Easily Bypass Vetting Process ∗∗∗ --------------------------------------------- Researchers have uncovered gaps in Amazons skill vetting process for the Alexa voice assistant ecosystem that could allow a malicious actor to publish a deceptive skill under any arbitrary developer name and even make backend code changes after approval to trick users into giving up sensitive information. --------------------------------------------- https://thehackernews.com/2021/02/alert-malicious-amazon-alexa-skills-can.h… ∗∗∗ So Unchill: Melting UNC2198 ICEDID to Ransomware Operations ∗∗∗ --------------------------------------------- Since its discovery in 2017 as a banking trojan, ICEDID evolved into a pernicious point of entry for financially motivated actors to conduct intrusion operations.

Amazon-Phishing Mails boomen derzeit! ∗∗∗ --------------------------------------------- Der Black Friday ist vorbei, Weihnachten steht vor der Tür und Österreich befindet sich nach wie vor im Lockdown. All das sind Gründe, wieso der Online-Handel derzeit boomt – genauso boomen jedoch betrügerische Nachrichten, die im Namen von Amazon verschickt werden. Aktuell kursieren E-Mails, bei denen BetrügerInnen Ihnen eine doppelte Abbuchung vorgaukeln, um an Ihre Daten zu kommen. --------------------------------------------- https://www.watchlist-internet.at/news/achtung-amazon-phishing-mails-boomen… ∗∗∗ Malware für den Diebstahl von Finanzdaten versteckt sich hinter Social-Media-Buttons ∗∗∗ --------------------------------------------- Die Buttons erlauben angeblich das Teilen von Inhalten per Facebook, Twitter und Instagram.

The more information an attacker can obtain on the victim the greater the chances for a successful exploitation and infiltration. Recently, we uncovered two information disclosure vulnerabilities affecting three of the major web browsers which can be leveraged to leak out a vast range of installed applications, including the presence of security products, allowing a threat actor to gain critical insights on the target. --------------------------------------------- https://www.fortinet.com/blog/threat-research/leaking-browser-url-protocol-… ===================== = Vulnerabilities = ===================== ∗∗∗ VMware Releases Security Updates to Address CVE-2020-4006 ∗∗∗ --------------------------------------------- VMware has released security updates to address a vulnerability—CVE-2020-4006—in VMware Workspace One Access, Access Connector, Identity Manager, and Identity Manager Connector.

One has found that the overwhelming majority of popular site operators haven’t learned from the 2016 Dyn/Mirai incident/attack and set up a backup DNS server, and the other has shown that the rate of DNS spoofing, though still very small, has more than doubled in less than seven years. --------------------------------------------- https://www.helpnetsecurity.com/2020/12/01/dns-spoofing/ ∗∗∗ Xanthe - Docker aware miner ∗∗∗ --------------------------------------------- Ransomware attacks and big-game hunting making the headlines, but adversaries use plenty of other methods to monetize their efforts in less intrusive ways.

Media files sent via text in the app are stored insecurely on a publicly accessible server. With some very minor scripting, it is trivial to throw a wide net around that content. While its not directly possible to link the media to specific users, those media files with faces, names, or other identifying characteristics do that for you.

The tool is called JARM and what it does is query TLS instances (HTTPS servers and services) to create a fingerprint of their TLS configuration.

(arXiv:2011.12978v1 [cs.CR]) ∗∗∗ --------------------------------------------- DNS is important in nearly all interactions on the Internet. All large DNS operators use IP anycast, announcing servers in BGP from multiple physical locations to reduce client latency and provide capacity. However, DNS is easy to spoof: third parties intercept and respond to queries for benign or malicious purposes. Spoofing is of particular risk for services using anycast, since service is already announced from multiple origins. --------------------------------------------- http://arxiv.org/abs/2011.12978 ===================== = Vulnerabilities = ===================== ∗∗∗ Sicherheitsupdate: Lücke in Trend Micro ServerProtect gefährdet Linux-Systeme ∗∗∗ --------------------------------------------- Es gibt eine abgesicherte Version von Trend Micro ServerProtect for Linux. --------------------------------------------- https://heise.de/-4974321 ∗∗∗ Security updates for Monday ∗∗∗ --------------------------------------------- Security updates have been issued by Arch Linux (c-ares, libass, raptor, rclone, and swtpm), Debian (libproxy, qemu, tcpflow, and x11vnc), Fedora (asterisk, c-ares, microcode_ctl, moodle, pam, tcpdump, and webkit2gtk3), Mageia (jruby and webkit2), openSUSE (buildah, c-ares, ceph, fontforge, java-1_8_0-openjdk, kernel, LibVNCServer, mariadb, thunderbird, ucode-intel, and wireshark), Red Hat (firefox, rh-mariadb103-mariadb and rh-mariadb103-galera, and thunderbird), SUSE (binutils, libssh2_org, [...] --------------------------------------------- https://lwn.net/Articles/838579/ ∗∗∗ Security Bulletin: A vulnerability in IBM Java Runtime affects TXSeries for Multiplatforms ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-a-vulnerability-in-ibm-ja… ∗∗∗ Security Bulletin: IBM QRadar Network Security is affected by Network Time Protocol (NTP) vulnerabilities (CVE-2020-11868, CVE-2020-13817) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-qradar-network-securi… ∗∗∗ Security Bulletin: A vulnerability in IBM Java Runtime affects TXSeries for Multiplatforms ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-a-vulnerability-in-ibm-ja… ∗∗∗ Security Bulletin: Vulnerability in IBM Java SDK affect IBM Content Classification ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-vulnerability-in-ibm-java… ∗∗∗ Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect IBM Content Classification ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-multiple-vulnerabilities-… ∗∗∗ Security Bulletin: IBM Content Classification is affected by a Eclipse Jetty (Publicly disclosed vulnerability) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-content-classificatio… ∗∗∗ Security Bulletin: A vulnerability in IBM Java Runtime affects IBM CICS TX on Cloud ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-a-vulnerability-in-ibm-ja… ∗∗∗ Security Bulletin: Eclipse Jetty (Publicly disclosed vulnerability) affects Content Classifaction ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-eclipse-jetty-publicly-di… ∗∗∗ Security Bulletin: A vulnerability in IBM Java Runtime affect IBM CICS TX on Cloud ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-a-vulnerability-in-ibm-ja… -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

Thus, in the attempt of preventing unauthorized third parties from accessing their accounts and sensitive data, companies are increasingly turning to biometric authentication. Contemporary Identity and Access Management (IAM) technologies have moved beyond basic login methods based on usernames and passwords. --------------------------------------------- https://heimdalsecurity.com/blog/iam-driven-biometrics/ ∗∗∗ [SANS ISC] Malicious Python Code and LittleSnitch Detection ∗∗∗ --------------------------------------------- I published the following diary on isc.sans.edu: “Malicious Python Code and LittleSnitch Detection“: We all run plenty of security tools on our endpoints.

For background, this particular honeypot is a full instance of WordPress running on a Docker image. The administrator credentials are intentionally weak, in order to give those with malicious intent easy access. This way I can examine what attacks the vulnerable site will undergo and what the login access will be used for. --------------------------------------------- https://blogs.akamai.com/sitr/2020/11/wordpress-malware-setting-up-seo-shop… ∗∗∗ Purgalicious VBA: Macro Obfuscation With VBA Purging ∗∗∗ --------------------------------------------- Malicious Office documents remain a favorite technique for every type of threat actor, from red teamers to FIN groups to APTs.

===================== = End-of-Day report = ===================== Timeframe: Dienstag 17-11-2020 18:00 − Mittwoch 18-11-2020 18:00 Handler: Dimitri Robl Co-Handler: Robert Waldner ===================== = News = ===================== ∗∗∗ When Security Controls Lead to Security Issues, (Wed, Nov 18th) ∗∗∗ --------------------------------------------- The job of security professionals is to protect customers assets and, even more, today, customers data. The security landscape is full of solutions that help to improve security by detecting (and blocking) threats knocking on the organizations doors. Sometimes, such solutions have side effects that go to the opposite direction and make customers more vulnerable to attacks. --------------------------------------------- https://isc.sans.edu/diary/rss/26804 ∗∗∗ Evasive Maneuvers in Data Stealing Gateways ∗∗∗ --------------------------------------------- We have already shared examples of many kinds of malware that rely on an external gateway to receive or return data, such as different malware payloads. During a recent investigation, we came across this example of a PHP script that attackers use for many different purposes. What makes the sample interesting is that alongside this PHP, we also found a few data-stealing scripts indicating that the code might have been used to send sensitive data to the attackers.

But what is it, and where did it come from? --------------------------------------------- https://blog.malwarebytes.com/pups/2020/11/webnavigator-chromium-browser-pu… ∗∗∗ Nibiru ransomware variant decryptor ∗∗∗ --------------------------------------------- The Nibiru ransomware is a .NET-based malware family. It traverses directories in the local disks, encrypts files with Rijndael-256 and gives them a .Nibiru extension. Rijndael-256 is a secure encryption algorithm. However, Nibiru uses a hard-coded string "Nibiru" to compute the 32-byte key and 16-byte IV values. The decryptor program leverages this weakness to decrypt files encrypted by this variant. --------------------------------------------- https://blog.talosintelligence.com/2020/11/Nibiru-ransomware.html ∗∗∗ Large-Scale Attacks Target Epsilon Framework Themes ∗∗∗ --------------------------------------------- On November 17, 2020, our Threat Intelligence team noticed a large-scale wave of attacks against recently reported Function Injection vulnerabilities in themes using the Epsilon Framework, which we estimate are installed on over 150,000 sites. So far today, we have seen a surge of more than 7.5 million attacks against more than 1.5 million sites ... For the time being, the vast majority of these attacks appear to be probing attacks, designed to determine whether a site has a vulnerable theme installed rather than to perform an exploit chain, though full Remote Code Execution(RCE) leading to site takeover is possible with these vulnerabilities. --------------------------------------------- https://www.wordfence.com/blog/2020/11/large-scale-attacks-target-epsilon-f… ∗∗∗ Vorsicht vor COVID-19-Hilfsfonds: Unterstützungszahlungen in Millionenhöhe sind Betrug! ∗∗∗ --------------------------------------------- Die Corona-Krise ist für viele Menschen auch eine finanzielle Krise. Verschiedene Unterstützungsangebote sollen daher helfen, durch diese Zeit zu kommen. Aber Achtung! Werfen Sie einen genauen Blick darauf, wer Ihnen Geld anbietet. Denn: Derzeit werden betrügerische E-Mails von angeblichen COVID-19 Hilfsfonds versendet, in denen hohe Geldbeträge versprochen werden. --------------------------------------------- https://www.watchlist-internet.at/news/vorsicht-vor-covid-19-hilfsfonds-unt… ===================== = Vulnerabilities = ===================== ∗∗∗ iTunes 12.11 for Windows ∗∗∗ --------------------------------------------- Foundation Impact: A local user may be able to read arbitrary files ImageIO Impact: Processing a maliciously crafted image may lead to arbitrary code execution libxml2 Impact: Processing maliciously crafted web content may lead to code execution libxml2 Impact: A remote attacker may be able to cause unexpected application termination or arbitrary code execution WebKit Impact: Processing maliciously crafted web content may lead to arbitrary code execution Windows Security Impact: A malicious application may be able to access local users Apple IDs --------------------------------------------- https://support.apple.com/kb/HT211933 ∗∗∗ Tails 4.13: Anonymisierendes Betriebssystem bekommt wichtige Sicherheitsupdates ∗∗∗ --------------------------------------------- Die neue Version des Debian-basierten Live-Systems umfasst ein wenig Feinschliff an der Oberfläche, vor allem aber wichtige Security-Fixes. --------------------------------------------- https://heise.de/-4963955 ∗∗∗ Tor Browser: Desktop-Version 10.0.5 mit Firefox-Sicherheitsupdates verfügbar ∗∗∗ --------------------------------------------- Für Windows, Linux und macOS steht eine neue Version des anonymisierenden Webbrowsers bereit.

It affects 645 different API actions across 40 different AWS services. This would be beneficial for a Penetration Tester or a Red Teamer to enumerate what permissions the role or user they’ve compromised has access to without alerting the blue team as no logs are generated in CloudTrail. --------------------------------------------- https://frichetten.com/blog/aws-api-enum-vuln/ ∗∗∗ Secret fragments: Remote code execution on Symfony based websites ∗∗∗ --------------------------------------------- This configuration value, secret, is also used, for instance, to build CSRF tokens and remember-me tokens. Given its importance, this value must obviously be very random. Unfortunately, we discovered that oftentimes, the secret either has a default value, or there exist ways to obtain the value, bruteforce it offline, or to purely and simply bypass the security check that it is involved with.
