Aber was ist der "Grüne Pass" und wie kann dieser genutzt werden? Der "Grüne Pass" kann in unterschiedlichen Formen genutzt werden: ausgedruckt, via App, als Foto etc. Wir zeigen Ihnen, wie Sie zu diesem kommen und worauf Sie achten sollten. --------------------------------------------- https://www.watchlist-internet.at/news/gruener-pass-worauf-sie-achten-muess… ∗∗∗ Ransomware: Interpol warnt vor exponentiellen Wachstum ∗∗∗ --------------------------------------------- Cyberkriminelle agieren laut Interpol über Grenzen hinweg und bleiben dabei meist ungestraft.

This tool, available on every UNIX flavor, allows system administrators to provide access to certain users/groups to certain commands as root or another user. This is performed with a lot of granularity in the access rights and logging/reporting features. I'm using it for many years and I'm still learning great stuff about it. Yesterday, at the Pass-The-Salt[2] conference, Peter Czanik presented a great feature of Sudo (available since version 1.9): the ability to extend features using Python modules! --------------------------------------------- https://isc.sans.edu/diary/rss/27614 ∗∗∗ Diving Deeper Into the Kaseya VSA Attack: REvil Returns and Other Hackers Are Riding Their Coattails ∗∗∗ --------------------------------------------- On, July 2nd, a massive ransomware attack was launched against roughly 50 managed services providers (MSPs) by criminals associated with the REvil ransomware-as-a-service (RaaS) group.

They remain an ever-growing threat to website owners. We’ve said many times on this blog that the attackers are constantly using new techniques to evade detection. In this post I will go over a case involving one such MageCart group. --------------------------------------------- https://blog.sucuri.net/2021/07/magecart-swiper-uses-unorthodox-concatenati… ∗∗∗ Microsoft struggles to wake from PrintNightmare: Latest print spooler patch can be bypassed, researchers say ∗∗∗ --------------------------------------------- I pity the spool / Updated / Any celebrations that Microsofts out-of-band patch had put a stop PrintNightmare shenanigans may have been premature. --------------------------------------------- https://go.theregister.com/feed/www.theregister.com/2021/07/07/printnightma… ∗∗∗ Kaseya Left Customer Portal Vulnerable to 2015 Flaw in its Own Software ∗∗∗ --------------------------------------------- Last week cybercriminals deployed ransomware to 1,500 organizations that provide IT security and technical support to many other companies. The attackers exploited a vulnerability in software from Kaseya, a Miami-based company whose products help system administrators manage large networks remotely. Now it appears Kaseyas customer service portal was left vulnerable until last week to a data-leaking security flaw that was first identified in the same software six years ago. --------------------------------------------- https://krebsonsecurity.com/2021/07/kaseya-left-customer-portal-vulnerable-… ∗∗∗ 3 things the Kaseya attack can teach us about ransomware recovery ∗∗∗ --------------------------------------------- Some lessons on dealing with ransomware recovery, thanks to the admirable transparency of a Dutch MSP impacted by the REvil attack on Kaseya. --------------------------------------------- https://blog.malwarebytes.com/ransomware/2021/07/3-things-the-kaseya-attack… ∗∗∗ Non-Malicious Android Crypto Mining Apps Scam Users at Scale ∗∗∗ --------------------------------------------- With no bad behavior, the mobile apps are difficult to detect by automated security scans --------------------------------------------- https://www.securityweek.com/non-malicious-android-crypto-mining-apps-scam-… ∗∗∗ Ransomware as a service: Negotiators are now in high demand ∗∗∗ --------------------------------------------- RaaS groups are hiring negotiators whose primary role is to force victims to pay up. --------------------------------------------- https://www.zdnet.com/article/ransomware-as-a-service-negotiators-between-h… ∗∗∗ Global Phishing Campaign Targets Energy Sector and its Suppliers ∗∗∗ --------------------------------------------- Our research team has found a sophisticated campaign, active for at least one year, targeting large international companies in the energy, oil & gas, and electronics industries.

The first encryption algorithm for that standard was GEA-1, a stream cipher built on three linear-feedback shift registers and a non-linear combining function. Although the algorithm has a 64-bit key, the effective key length is only 40 bits, due to “an exceptional interaction of the deployed LFSRs and the key initialization, which is highly unlikely to occur by chance. --------------------------------------------- https://www.schneier.com/blog/archives/2021/06/intentional-flaw-in-gprs-enc… ∗∗∗ Malicious Redirects Through Bogus Plugin ∗∗∗ --------------------------------------------- Recently we have been seeing a rash of WordPress website compromises with attackers abusing the plugin upload functionality in the wp-admin dashboard to redirect visitors and website owners to malicious websites. --------------------------------------------- https://blog.sucuri.net/2021/06/malicious-redirects-through-bogus-plugin.ht… ∗∗∗ Smoking Out a DARKSIDE Affiliate’s Supply Chain Software Compromise ∗∗∗ --------------------------------------------- Mandiant observed DARKSIDE affiliate UNC2465 accessing at least one victim through a Trojanized software installer downloaded from a legitimate website. --------------------------------------------- https://www.fireeye.com/blog/threat-research/2021/06/darkside-affiliate-sup… ∗∗∗ Mit diesem Leitfaden der NSA können Admins IP-Telefonie schützen ∗∗∗ --------------------------------------------- Die National Security Agency spricht Empfehlungen aus, wie Sprach- und Videoanrufe sicherer werden. --------------------------------------------- https://heise.de/-6111092 ∗∗∗ Polazert Trojan using poisoned Google Search results to spread ∗∗∗ --------------------------------------------- The threat actors behind Trojan.Polazert are using keyword-stuffed PDF files to rank high in search results and attract new victims.Categories: AwarenessTags: Polazertratseo poisoningSolarMarkerstuffed PDF(Read more...)The post Polazert Trojan using poisoned Google Search results to spread appeared first on Malwarebytes Labs. --------------------------------------------- https://blog.malwarebytes.com/awareness/2021/06/polazert-trojan-using-poiso… ∗∗∗ Service Vulnerabilities: Shared Hosting Symlink Security Issue Still Widely Exploited on Unpatched Servers ∗∗∗ --------------------------------------------- The Wordfence site cleaning team helps numerous customers recover from malware infections and site intrusions.

We have covered before how we can create a snapshot of the OS disk of a running VM. Snapshotting and then killing off the infected VM is very straight forward, but it also tips off an intruder that he has been found out. Sometimes, it makes sense to first watch for a while, and learn more, for example about compromised accounts, lateral movement, or other involved hosts. --------------------------------------------- https://isc.sans.edu/diary/rss/27536 ∗∗∗ Top 5 ICS Incident Response Tabletops and How to Run Them ∗∗∗ --------------------------------------------- In this blog SANS instructor, Dean Parsons, discusses the top five ICS incident response table tops and how to run them. How prepared is your organization to respond to an industrial control system (ICS) cyber incident? How resilient is it against Ransomware that could impact safety and operations? Does your organization have the ability to detect advanced persistent threats that use modern attack methodologies against your critical infrastructure? --------------------------------------------- https://www.sans.org/blog/top-5-ics-incident-response-tabletops-and-how-to-… ∗∗∗ What you need to know about Process Ghosting, a new executable image tampering attack ∗∗∗ --------------------------------------------- This blog describes a new executable image tampering attack similar to, but distinct from, Doppelgänging and Herpaderping. With this technique, an attacker can write a piece of malware to disk in such a way that it’s difficult to scan or delete it — and where it then executes the deleted malware as though it were a regular file on disk. This technique does not involve code injection, process hollowing, or Transactional NTFS (TxF). --------------------------------------------- https://www.elastic.co/blog/process-ghosting-a-new-executable-image-tamperi… ∗∗∗ Google schickt Framework gegen Supply-Chain-Angriffe ins Rennen ∗∗∗ --------------------------------------------- SLSA soll die Integrität von Code vom Einchecken ins Repository über den Build-Prozess bis zum Verwenden von Paketen sicherstellen. --------------------------------------------- https://heise.de/-6073057 ∗∗∗ Cybercriminals go after Amazon Prime Day Shoppers ∗∗∗ --------------------------------------------- - In the last 30 days, over 2300 new domains were registered about Amazon, a 10% increase from the previous Amazon Prime Day, where the majority now are either malicious or suspicious - Almost 1 out of 2 (46%) of new domains registered containing the word “Amazon” are malicious - Almost 1 out of 3 (32%) of new domains registered with the word “Amazon” are deemed suspicious --------------------------------------------- https://blog.checkpoint.com/2021/06/16/cybercriminals-go-after-amazon-prime… ===================== = Vulnerabilities = ===================== ∗∗∗ Hitachi Application Server Help vulnerable cross-site scripting ∗∗∗ --------------------------------------------- The following products are affected by the vulnerability. * Hitachi Application Server V10 Manual (Windows) version 10-11-01 and earlier * Hitachi Application Server V10 Manual (UNIX) version 10-11-01 and earlier Solution: Apply the appropriate latest version of the help according to the information provided by the developer. --------------------------------------------- https://jvn.jp/en/jp/JVN03776901/ ∗∗∗ Chaos Tool Suite (ctools) - Moderately critical - Access bypass - SA-CONTRIB-2021-015 ∗∗∗ --------------------------------------------- Chaos tool suite (ctools) module provides a number of APIs and extensions for Drupal, its 8.x-3.x branch is a start from scratch to evaluate the features of ctools that didnt make it into Drupal Core 8.0.x and port them.The module doesnt sufficiently handle block access control on its EntityView plugin. --------------------------------------------- https://www.drupal.org/sa-contrib-2021-015 ∗∗∗ Block Content Revision UI - Moderately critical - Access bypass - SA-CONTRIB-2021-017 ∗∗∗ --------------------------------------------- This module provides a revision UI to Block Content entities.The module doesnt sufficiently respect access restrictions to certain entities when used in conjunction with specific modules.This vulnerability is mitigated by the fact that an attacker must have a role with any of the permissions provided by Block Content Revision UI, and another affected module must be enabled. --------------------------------------------- https://www.drupal.org/sa-contrib-2021-017 ∗∗∗ Linky Revision UI - Moderately critical - Access bypass - SA-CONTRIB-2021-016 ∗∗∗ --------------------------------------------- This module provides a revision UI to Linky entities.The module doesnt sufficiently respect access restrictions to certain entities when used in conjunction with specific modules.This vulnerability is mitigated by the fact that an attacker must have a role with any of the permissions provided by Linky Revision UI, and another affected module must be enabled. --------------------------------------------- https://www.drupal.org/sa-contrib-2021-016 ∗∗∗ Cisco Security Advisories ∗∗∗ --------------------------------------------- Cisco hat Security Advisories zu acht Schwachstellen veröffentlicht.

Vergleichbare Angriffe gab es global auch schon ab August 2020 unter ähnlichen Namen. Nachdem wir Meldungen von Partner-CERTs an uns über Angriffe auf Ziele in anderen EU Staaten bekommen haben, sind jetzt auch in Österreich einige Fälle aufgetreten. --------------------------------------------- https://cert.at/de/warnungen/2021/6/ddos-angriffe-gegen-unternehmen-in-oste… ∗∗∗ Password Attacks 101 ∗∗∗ --------------------------------------------- According to the 2020 Data Breaches report by Verizon, 25% of all breaches involved the use of stolen credentials. And for small businesses, that number hit 30%. Brute force attacks have a similar share, accounting for 18% of all breaches, and 34% of those for small businesses. Why are password attacks like brute forcing so effective? And how exactly do they work? Let’s take a look at three kinds of password attacks that present a real threat to sites and businesses of all sizes. --------------------------------------------- https://blog.sucuri.net/2021/06/3-password-attacks-101.html ∗∗∗ Macher der Ransomware Avaddon geben auf und veröffentlichen Schlüssel ∗∗∗ --------------------------------------------- Es ist ein kostenloses Entschlüsselungstool für Opfer des Erpressungstrojaners Avaddon erschienen. --------------------------------------------- https://heise.de/-6070028 ∗∗∗ Malicious Attack Campaign Targeting Jetpack Users Reusing Passwords ∗∗∗ --------------------------------------------- The Wordfence Threat Intelligence and Site Cleaning teams have been tracking a malware campaign that redirects all site visitors to malvertising domains, while attempting to keep site administrators unaware of the infection. Since June 1, 2021, the number of sites we are tracking that have been infected with this malware has more than doubled, and we expect this campaign to continue gaining momentum as it relies on a mechanism that is difficult to block directly. --------------------------------------------- https://www.wordfence.com/blog/2021/06/malicious-attack-campaign-targeting-… ∗∗∗ Micropatch for Another Remote Code Execution Issue in Internet Explorer (CVE-2021-31959) ∗∗∗ --------------------------------------------- Windows Updates brought a fix for another "Exploitation More Likely" memory corruption vulnerability in Scripting Engine (CVE-2021-26419) discovered by Ivan Fratric of Google Project Zero, very similar to this vulnerability discovered also discovered by Ivan and patched in May.Ivan published details and a proof-of-concept three days ago and we took these to reproduce the vulnerability in our lab and create a micropatch for it. --------------------------------------------- https://blog.0patch.com/2021/06/micropatch-for-another-remote-code.html ∗∗∗ Stealing tokens, emails, files and more in Microsoft Teams through malicious tabs ∗∗∗ --------------------------------------------- I recently came across an interesting bug in the Microsoft Power Apps service which, despite its simplicity, can be leveraged by an attacker to gain persistent read/write access to a victim user’s email, Teams chats, OneDrive, Sharepoint and a variety of other services by way of a malicious Microsoft Teams tab and Power Automate flows. The bug has since been fixed by Microsoft, but in this blog we’re going to see how it /could/ have been exploited. --------------------------------------------- https://medium.com/tenable-techblog/stealing-tokens-emails-files-and-more-i… ===================== = Vulnerabilities = ===================== ∗∗∗ High Severity Vulnerability Patched in WooCommerce Stock Manager Plugin ∗∗∗ --------------------------------------------- We initially reached out to the plugin’s developer on May 21, 2021.
