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.

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.

Masscan is perfectly good as a blunt instrument to quickly find open TCP ports across large address spaces, but for fine details it is better to use a scanner like nmap that, while much slower, is able to probe the port to get a better idea of what is running. --------------------------------------------- https://isc.sans.edu/diary/rss/27480 ∗∗∗ Guildma is now using Finger and Signed Binary Proxy Execution to evade defenses, (Mon, May 31st) ∗∗∗ --------------------------------------------- We recently identified a new Guildma/Astaroth campaign targeting South America, mainly Brazil, using a new variant of the malware. Guildma is known by its multiple-staged infection chain and evasion techniques to reach victim’s data and exfiltrate them.
