Our tool detects BEHAVIOURS". That was like 15 years ago. Fast forward to today, with many of the same vendors now selling "threat intelligence feeds" for good money, and the most frequent attributes pushed over these feeds are MD5/SHA1 hashes and IP addresses.

So if you are an attacker or need to test your environment then you have plenty of options. As defenders, we also have options for detection on the network. --------------------------------------------- https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/network-det… ∗∗∗ Evasive URLs in Spam: Part 2 ∗∗∗ --------------------------------------------- A URL can be completely valid, yet still misleading.

Most of these incidents are the result of a phishing email coercing a user to enter their credentials used for accessing M365 into a phishing site. Other incidents have been a result of password spraying, password stuffing, or simple brute force attempts against M365 tenants. In almost all of these incidents, the user or account was not protected by multi-factor authentication (MFA). --------------------------------------------- http://www.fireeye.com/blog/threat-research/2020/09/detecting-microsoft-365… ∗∗∗ Three immediate steps to take to protect your APIs from security risks ∗∗∗ --------------------------------------------- In one form or another, APIs have been around for years, bringing the benefits of ease of use, efficiency and flexibility to the developer community. The advantage of using APIs for mobile and web apps is that developers can build and deploy functionality and data integrations quickly.

Successful exploitation could allow execution of arbitrary code on the affected device or cause denial of service scenario. --------------------------------------------- https://www.zeroscience.mk/en/vulnerabilities/ZSL-2020-5596.php ∗∗∗ Vulnerability Spotlight: Remote code execution bugs in NVIDIA D3D10 driver ∗∗∗ --------------------------------------------- Cisco Talos recently discovered multiple remote code execution vulnerabilities in the NVIDIA D3D10 driver. This driver supports multiple GPUs that NVIDIA produces.

Of course, this is not the only source of interesting malicious messages in our inboxes - sometimes the phishing authors "cut out the middleman" and send their creations directly to us. Last week, this was the case with a slightly unusual (and slightly broken) phishing, which tries to use legitimate pages overlaid with a fake login prompt. --------------------------------------------- https://isc.sans.edu/diary/rss/26586 ∗∗∗ The Hidden PHP Malware that Reinfects Cleaned Files ∗∗∗ --------------------------------------------- Website reinfections are a serious problem for website owners, and it can often be difficult to determine the cause behind the reinfection — especially if you lack access to necessary logs, which is usually the case for shared hosting services. Some of the more common causes of reinfections are issues like cross- site contamination or unpatched website software security vulnerabilities that get re-exploited. --------------------------------------------- https://blog.sucuri.net/2020/09/the-hidden-php-malware-that-reinfects-clean… ∗∗∗ One Part Steganography, Four Redirectors, and a Splash of C2! ∗∗∗ --------------------------------------------- What do you get when you combine Google Images, QR Codes, and Remote Command Execution?

September 2020 kam es zu einem IT-Sicherheitsvorfall im Universitätsklinikum Düsseldorf (UKD). Gemäß BSI-Gesetz hat das UKD das Bundesamt für Sicherheit in der Informationstechnik (BSI) über diesen Vorfall informiert. [...] In diesem Zusammenhang weist das BSI mit Nachdruck darauf hin, dass derzeit eine seit Januar 2020 bekannte Schwachstelle (CVE-2019-19781) in VPN-Produkten der Firma Citrix für Cyber-Angriffe ausgenutzt wird. Dem BSI werden zunehmend Vorfälle bekannt, bei denen Citrix-Systeme bereits vor der Installation der im Januar 2020 bereitgestellten Sicherheitsupdates kompromittiert wurden. Dadurch haben Angreifer auch nach Schließung der Sicherheitslücke weiterhin Zugriff auf das System und dahinterliegende Netzwerke. Diese Möglichkeit wird aktuell vermehrt ausgenutzt, um Angriffe auf betroffene Organisationen durchzuführen. --------------------------------------------- https://www.bsi.bund.de/DE/Presse/Pressemitteilungen/Presse2020/UKDuesseldo… ∗∗∗ Evasive URLs in Spam ∗∗∗ --------------------------------------------- Cybercriminals are continuously evolving their tools, tactics, and techniques to evade spam detection systems.

A GUI generally makes the tool easier to use — and certainly more visually appealing than just raw text. One example of web malware that uses GUIs are PHP webshells like r57. --------------------------------------------- https://blog.sucuri.net/2020/09/phpbash-terminal-editor-web-shell.html ∗∗∗ GuLoaders VM-Exit Instruction Hammering explained ∗∗∗ --------------------------------------------- In Joe Sandbox Cloud Basic, our community version of Joe Sandbox, we often get very interesting and recent malware samples. On the September 16th, 2020 we came across a new GuLoader variant (MD5: 01a54f73856cfb74a3bbba47bcec227b).

Specifically, an attacker could trigger a use-after-free condition in WebCore, the DOM-rendering system for Webkit used in Safari. This could give the attacker the ability to execute remote code on the victim machine. --------------------------------------------- https://blog.talosintelligence.com/2020/09/vuln-spotlight-apple-safari-sept… ∗∗∗ High-Severity Vulnerabilities Patched in Discount Rules for WooCommerce ∗∗∗ --------------------------------------------- On August 20, 2020, the Wordfence Threat Intelligence team was made aware of several vulnerabilities that had been patched in Discount Rules for WooCommerce, a WordPress plugin installed on over 40,000 sites. --------------------------------------------- https://www.wordfence.com/blog/2020/09/high-severity-vulnerabilities-patche… ∗∗∗ Security updates for Thursday ∗∗∗ --------------------------------------------- Security updates have been issued by Fedora (dotnet3.1, kernel, mbedtls, and python35), Mageia (libraw), openSUSE (mumble), SUSE (libsolv, libzypp, and perl-DBI), and Ubuntu (libdbi-perl, libphp-phpmailer, mcabber, ncmpc, openssl, openssl1.0, qemu, samba, storebackup, and util-linux). --------------------------------------------- https://lwn.net/Articles/831720/ ∗∗∗ Synology-SA-20:21 Zerologon ∗∗∗ --------------------------------------------- A vulnerability allows remote attackers to bypass security constraints via a susceptible version of Synology Directory Server. --------------------------------------------- https://www.synology.com/en-global/support/security/Synology_SA_20_21 ∗∗∗ Citrix Application Delivery Controller, Citrix Gateway, and Citrix SD-WAN WANOP appliance Security Update ∗∗∗ --------------------------------------------- Multiple vulnerabilities have been discovered in Citrix ADC (formerly known as NetScaler ADC), Citrix Gateway (formerly known as NetScaler Gateway) and Citrix SD-WAN WANOP appliance models 4000-WO, 4100-WO, 5000-WO, and 5100-WO. --------------------------------------------- https://support.citrix.com/article/CTX281474 ∗∗∗ Security Bulletin: Vulnerabilities in WebSphere Application Server affect IBM Cloud Orchestrator and IBM Cloud Orchestrator Enterprise ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-vulnerabilities-in-websph… ∗∗∗ Security Bulletin: IBM Aspera Shares 1.9.14 Patch Level 1 and earlier are vulnerable to DOM XSS ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-aspera-shares-1-9-14-… ∗∗∗ Security Bulletin: Denial of service vulnerability in WebSphere Application Server Liberty (CVE-2020-4590) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-denial-of-service-vulnera… -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

Dieses Problem könnte dazu missbraucht werden, Windows-Server, die als Domänencontroller in Unternehmensnetzwerken laufen, einfach zu übernehmen. --------------------------------------------- https://www.zdnet.de/88382688/zerologon-uebernimmt-domain-controller/ ∗∗∗ Magento stores hit by largest automated hacking attack since 2015 ∗∗∗ --------------------------------------------- In the largest automated hacking campaign against Magento sites, attackers compromised almost 2,000 online stores this weekend to steal credit cards. --------------------------------------------- https://www.bleepingcomputer.com/news/security/magento-stores-hit-by-larges… ∗∗∗ Creating patched binaries for pentesting purposes, (Sun, Sep 13th) ∗∗∗ --------------------------------------------- When doing pentestings, the establishment of backdoors is vital to be able to carry out lateral movements in the network or to reach the stage of action on objectives.

The client-side sometimes restricts file types, but the server-side does not allowing attackers with direct server access to upload files of any type including malicious files designed to compromise clients that view the data. OnBase also appears to lack the proper mechanisms to verify that files are of the type claimed and instead relies on file extensions, allowing attackers to upload malicious files whose extensions do not match the actual file type. This allows a second vector for malicious file upload and attacking clients. --------------------------------------------- https://cxsecurity.com/issue/WLB-2020090071 ∗∗∗ WordPress Plugin Flaw Allows Attackers to Forge Emails ∗∗∗ --------------------------------------------- The high-severity flaw in the Email Subscribers & Newsletters plugin by Icegram affects more than 100,000 WordPress websites. --------------------------------------------- https://threatpost.com/wordpress-plugin-flaw/159172/ ∗∗∗ Sicherheitsupdates: Root-Lücke bedroht Firewalls von Palo Alto ∗∗∗ --------------------------------------------- Eine kritische Lücke im Betriebssystem PAN-OS gefährdet Firewalls aus dem Hause Palo Alto. --------------------------------------------- https://heise.de/-4892796 ∗∗∗ Security updates for Monday ∗∗∗ --------------------------------------------- Security updates have been issued by CentOS (thunderbird), Debian (libproxy, qemu, and wordpress), Fedora (ansible, chromium, community-mysql, dotnet-build-reference-packages, dotnet3.1, drupal7, grub2, java-1.8.0-openjdk-aarch32, kernel, kernel-headers, kernel-tools, mingw-gnutls, php-symfony4, python-django, and selinux-policy), Gentoo (DBI, file-roller, gnome-shell, gst-rtsp-server, nextcloud-client, php, proftpd, qtgui, and zeromq), openSUSE (gimp, libjpeg-turbo, openldap2, [...] --------------------------------------------- https://lwn.net/Articles/831524/ ∗∗∗ Vulnerabilities Expose Thousands of MobileIron Servers to Remote Attacks ∗∗∗ --------------------------------------------- Researchers have disclosed the details of several potentially serious vulnerabilities affecting MobileIron’s mobile device management (MDM) solutions, including a flaw that can be exploited by an unauthenticated attacker for remote code execution on affected servers. --------------------------------------------- https://www.securityweek.com/vulnerabilities-expose-thousands-mobileiron-se… ∗∗∗ Multiple vulnerabilities in Buffalo AirStation WHR-G54S ∗∗∗ --------------------------------------------- https://jvn.jp/en/jp/JVN09166495/ ∗∗∗ Security Bulletin: IBM Cloud Pak System is affected by a vulnerability in VMware component ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-cloud-pak-system-is-a… ∗∗∗ Security Bulletin: A vulnerability in Apache AvtiveMQ affects IBM Operations Analytics Predictive Insights (CVE-2020-1941) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-a-vulnerability-in-apache… ∗∗∗ Security Bulletin: Vulnerability in libcurl affects the OS image for RedHat Enterprise Linux for IBM Cloud Pak System (CVE-2019-5436) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-vulnerability-in-libcurl-… ∗∗∗ Security Bulletin: Vulnerability in OpenSSL library affects OS Pattern Kit used in IBM Cloud Pak System ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-vulnerability-in-openssl-… ∗∗∗ Security Bulletin: IBM Kenexa LMS On Premise -IBM SDK, Java Technology Edition Quarterly CPU -Jul 2020 – Includes Oracle Jul 2020 CPU plus one additional vulnerability ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-kenexa-lms-on-premise… ∗∗∗ Security Bulletin: IBM Kenexa LCMS Premier On Premise – [All] jQuery (Publicly disclosed vulnerability) CVEID: 180875 ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-kenexa-lcms-premier-o… ∗∗∗ Security Bulletin: Vulnerability in side channel in Intel CPUs affect IBM Cloud Pak System (CVE-2019-11135) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-vulnerability-in-side-cha… ∗∗∗ Security Bulletin: IBM Kenexa LCMS Premier On Premise – [All] jQuery (Publicly disclosed vulnerability) CVE-2020-11023, CVE-2020-11022 ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-kenexa-lcms-premier-o… ∗∗∗ Security Bulletin: Multiple vulnerabilities in IBM Java SDK addressed in IBM Cloud Pak System (April 2020 updates) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-multiple-vulnerabilities-… -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

Unfortunately, attackers are also aware that many websites are straggling with their Magento migrations and post compromise tools have been created to support deployment for both Magento 1.x and 2.x versions, making it easier for them to exploit a larger number of sites. --------------------------------------------- https://blog.sucuri.net/2020/08/magento-multiversion-1-x-2-x-backdoor.html ∗∗∗ Extensive file permissions on service executable in Eikon Thomson Reuters (CVE-2019-10679) ∗∗∗ --------------------------------------------- SEC Consult found a vulnerability that allows unprivileged users to escalate their privileges to SYSTEM in Eikon of Thomson Reuters.

Making executables extremely large is not an uncommon technique among malware authors[1], as it allows them to easily avoid detection by most AV solutions, since the size of files which AVs will check is usually fairly low (tens of megabytes at most). --------------------------------------------- https://isc.sans.edu/diary/rss/26464 ∗∗∗ XCSSET: Mac-Malware infiziert Xcode-Projekte ∗∗∗ --------------------------------------------- Der Schädling setzt auf 0-day-Exploits, um Nutzerdaten zu klauen.

It requires collecting diverse intelligence, analyzing it and deciding who is responsible. Rarely does the evidence available to researchers reach a level of proof that would be acceptable in a court of law. Nevertheless, the private sector rises to the challenge to attempt to associate cyber attacks to threat actors using the intelligence available to them. --------------------------------------------- https://blog.talosintelligence.com/2020/08/attribution-puzzle.html ∗∗∗ Kriminelle versuchen durch seriöse Programme Schadsoftware zu verbreiten! ∗∗∗ --------------------------------------------- Die meisten Menschen vertrauen bekannten Softwareherstellerinnen und -herstellern, wenn diese eine App, ein Programm oder ein anderes Produkt aktualisieren oder ein neues Produkt auf den Markt bringen.

During a routine investigation, we detected a similar issue. Instead of targeting .ico files, however, attackers chose to inject content into real .png files — both on compromised sites and in booby trapped Magento repos on GitHub.

Cybersecurity has become even more high profile during the current COVID-19 pandemic. A recent warning from the UK National Cyber Security Centre and the US Department of Homeland Security talks of state-backed hackers targeting healthcare organizations. Many other examples of pandemic-focused cyberattacks have popped up since the coronavirus appeared. --------------------------------------------- https://resources.infosecinstitute.com/top-8-tips-for-office-security-when-… ∗∗∗ Web skimming with Google Analytics ∗∗∗ --------------------------------------------- Recently, we identified several cases where Google Analytics was misused: attackers injected malicious code into sites, which collected all the data entered by users, and then sent it via Analytics. --------------------------------------------- https://securelist.com/web-skimming-with-google-analytics/97414/ ∗∗∗ Pi Zero HoneyPot , (Sat, Jun 20th) ∗∗∗ --------------------------------------------- The ISC has had a Pi honeypot(1) for the last couple of years, but I haven't had much time to try it on the Pi zero.

But people who dont take advantage of these added safeguards may find it far more difficult to regain access when their account gets hacked, because increasingly thieves will enable multi-factor options and tie the account to a device they control. Heres the story of one such incident. --------------------------------------------- https://krebsonsecurity.com/2020/06/turn-on-mfa-before-crooks-do-it-for-you/ ∗∗∗ Achtung vor gefährlicher "BawagPSK" Phishing-SMS ∗∗∗ --------------------------------------------- BetrügerInnen senden derzeit eine SMS-Nachricht im Namen der BAWAG P.S.K. aus.
