===================== = End-of-Day report = ===================== Timeframe: Donnerstag 25-02-2021 18:00 − Freitag 26-02-2021 18:00 Handler: Dimitri Robl Co-Handler: Thomas Pribitzer ===================== = News = ===================== ∗∗∗ So where did those Satori attacks come from?, (Thu, Feb 25th) ∗∗∗ --------------------------------------------- Last week I posted about a new Satori variant scanning on TCP port 26 that I was picking up in my honeypots. Things have slowed down a bit, but levels are still above where they had been since mid-July 2020 on port 26. --------------------------------------------- https://isc.sans.edu/diary/rss/27140 ∗∗∗ SQL Triggers in Website Backdoors ∗∗∗ --------------------------------------------- Over the past year, there’s been an increasing trend of WordPress malware using SQL triggers to hide malicious SQL queries within compromised databases. 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. In earlier years, ICEDID was deployed to primarily target banking credentials. --------------------------------------------- https://www.fireeye.com/blog/threat-research/2021/02/melting-unc2198-icedid… ∗∗∗ SilentFade virus strikes, Cyberstalking and Ransom user ∗∗∗ --------------------------------------------- Recently, 360 Security Center monitored that the SlientFade virus was bundled with pirated software to spread. The infected users were mainly distributed in Malaysia, India, [...] --------------------------------------------- https://blog.360totalsecurity.com/en/silentfade-virus-strikes-cyberstalking… ∗∗∗ Microsoft Releases Open Source Resources for Solorigate Threat Hunting ∗∗∗ --------------------------------------------- Microsoft on Thursday announced the open source availability of CodeQL queries that it used during its investigation into the SolarWinds attack. --------------------------------------------- https://www.securityweek.com/microsoft-releases-open-source-resources-solor… ∗∗∗ Kettenbrief-Alarm: Angebliches Amazon-Gewinnspiel macht auf WhatsApp die Runde! ∗∗∗ --------------------------------------------- Auf WhatsApp wird derzeit ein Link verschickt mit einem Gewinn-Versprechen anlässlich des angeblichen 30-Jahr-Jubiläums von Amazon. Wir haben uns die Nachricht und den Link genauer angeschaut. Unser Fazit: Es handelt sich um einen klassischen Kettenbrief. Gewinn erhalten Sie dabei keinen, stattdessen müssen Sie eine gefährliche App herunterladen. --------------------------------------------- https://www.watchlist-internet.at/news/kettenbrief-alarm-angebliches-amazon… ∗∗∗ Go malware is now common, having been adopted by both APTs and e-crime groups ∗∗∗ --------------------------------------------- There's been a 2,000% increase of new malware written in Go over the past few years. --------------------------------------------- https://www.zdnet.com/article/go-malware-is-now-common-having-been-adopted-… ∗∗∗ New Phishing Attack Using Malformed URL Prefixes ∗∗∗ --------------------------------------------- GreatHorn reports on a phishing technique that leverages malformed URL prefixes to bypass security scanners. Many security scanners use pattern recognition to identify URLs, thus expecting the presence of "http://" to identify them. However, the URL specification technically does not require the "//" in order to visit a URL. --------------------------------------------- https://exchange.xforce.ibmcloud.com/collection/c52464bd46eb48e4c5741df9e1b… ===================== = Vulnerabilities = ===================== ∗∗∗ Google looks at bypass in Chromiums ASLR security defense, throws hands up, wont patch garbage issue ∗∗∗ --------------------------------------------- In early November, a developer contributing to Googles open-source Chromium project reported a problem with Oilpan, the garbage collector for the browsers Blink rendering engine: it can be used to break a memory defense known as address space layout randomization (ASLR). --------------------------------------------- https://go.theregister.com/feed/www.theregister.com/2021/02/26/chrome_aslr_… ∗∗∗ Security Advisory for Multiple Vulnerabilities on Some Routers, Satellites, and Extenders ∗∗∗ --------------------------------------------- NETGEAR has released fixes for multiple security vulnerabilities on the following product models: BR200, running firmware

NukeSped). While investigating this activity, we were able to observe the complete life cycle of an attack, uncovering more technical details and links to the group’s other campaigns. --------------------------------------------- https://securelist.com/lazarus-threatneedle/100803/ ∗∗∗ Forensicating Azure VMs, (Thu, Feb 25th) ∗∗∗ --------------------------------------------- With more and more workloads migrating to "the Cloud", we see post-breach forensic investigations also increasingly moving from on-premises to remote instances. If we are lucky and the installation is well engineered, we will encounter a "managed" virtual machine setup, where a forensic agent or EDR (endpoint detection & response) product is pre-installed on our affected VM.
