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. Their goal is to protect us by preventing infection (or trying to prevent it).

[...] Once any of these malware strains are detected, system administrators should drop everything, take systems offline, and audit and remove the malware as a top priority. ZDNet will keep the list up to date going forward. --------------------------------------------- https://www.zdnet.com/article/the-malware-that-usually-installs-ransomware-… ∗∗∗ Exploiting dynamic rendering engines to take control of web apps ∗∗∗ --------------------------------------------- tl;dr: - Dynamic rendering is a technique used to serve prerendered web site pages to crawlers (e.g., Google search engine, Slack or Twitter bots, etc.) - The most popular open source applications for dynamic rendering are Rendertron and Prerender; both of which may introduce vulnerabilities to a network if used improperly. --------------------------------------------- https://r2c.dev/blog/2020/exploiting-dynamic-rendering-engines-to-take-cont… ∗∗∗ Consul by HashiCorp: from Infoleak to RCE ∗∗∗ --------------------------------------------- Consul is a software first released in 2014 for DNS-based service discovery. It provides distributed key-value storage, segmentation, and configuration. Registered services and nodes can be queried using a DNS interface or an HTTP interface. [...] An attacker can use public access to the system to obtain information about the infrastructure and its configuration. --------------------------------------------- https://lab.wallarm.com/consul-by-hashicorp-from-infoleak-to-rce/ ∗∗∗ WordPress Malware Setting Up SEO Shops ∗∗∗ --------------------------------------------- While recently looking over my honeypots, I discovered an infection where a malicious actor added a storefront on top of my existing WordPress installation. 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.

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.
