The concern was whether the linked-to site was only a generic credential stealing web page or something targeted/potentially more dangerous. Luckily, it was only a run-of-the-mill phishing kit login page, nevertheless, the e-mail message itself turned out to be somewhat more interesting, since although it didn’t look like anything special, it did make it to the recipient’s inbox, instead of the e-mail quarantine where it should have ended up. --------------------------------------------- https://isc.sans.edu/diary/rss/31084 ∗∗∗ Konfety Ad Fraud Uses 250+ Google Play Decoy Apps to Hide Malicious Twins ∗∗∗ --------------------------------------------- Details have emerged about a "massive ad fraud operation" that leverages hundreds of apps on the Google Play Store to perform a host of nefarious activities. --------------------------------------------- https://thehackernews.com/2024/07/konfety-ad-fraud-uses-250-google-play.html ∗∗∗ DarkGate, the Swiss Army knife of malware, sees boom after rival Qbot crushed ∗∗∗ --------------------------------------------- Meet the new boss, same as the old boss The DarkGate malware family has become more prevalent in recent months, after one of its main competitors was taken down by the FBI. --------------------------------------------- https://go.theregister.com/feed/www.theregister.com/2024/07/16/darkgate_mal… ∗∗∗ Hackers Claim to Have Leaked 1.1 TB of Disney Slack Messages ∗∗∗ --------------------------------------------- A hacker group called “NullBulge” says it stole more than a terabyte of Disneys internal Slack messages and files from nearly 10,000 channels in an apparent protest over AI-generated art. --------------------------------------------- https://www.wired.com/story/disney-slack-leak-nullbulge/ ∗∗∗ Kaspersky Leaving US Following Government Ban ∗∗∗ --------------------------------------------- Kaspersky is shutting down operations in the US and laying off employees following the recent Commerce Department ban. --------------------------------------------- https://www.securityweek.com/kaspersky-leaving-us-following-government-ban/ ∗∗∗ Beware of BadPack: One Weird Trick Being Used Against Android Devices ∗∗∗ --------------------------------------------- Our data shows a pattern of APK malware bundled as BadPack files.

The data is segmented by global volume, industry and geography. These cyber attack numbers were driven by a variety of reasons, ranging from the continued increase in digital transformation and the growing sophistication of cybercriminals using advanced techniques like AI and machine learning. --------------------------------------------- https://blog.checkpoint.com/research/check-point-research-reports-highest-i… ∗∗∗ Punch Card Hacking – Exploring a Mainframe Attack Vector ∗∗∗ --------------------------------------------- Mainframes are the unseen workhorses that carry the load for many services we use on a daily basis: Withdrawing money from an ATM, credit card payments, and airline reservations to name just a few of the high volume workloads that are primarily handled by mainframes.

===================== = End-of-Day report = ===================== Timeframe: Freitag 12-07-2024 18:00 − Montag 15-07-2024 18:00 Handler: Michael Schlagenhaufer Co-Handler: n/a ===================== = News = ===================== ∗∗∗ Neue Absenderadresse für unsere täglichen Mails an Netzbetreiber ∗∗∗ --------------------------------------------- Wir versenden jeden Tag zwischen 150 und 250 Mails an unsere Kontakte bei Netzbetreibern in Österreich, um diese über Probleme in ihren Netzen zu informieren, die wir (bzw. unsere Datenquellen) dort gefunden haben. [..] Jetzt haben wir uns dazu entschlossen, den gleichen Weg zu nehmen, den schon viele andere Firmen beschritten haben: Wir senden ab sofort diese Mails nicht mehr von team(a)cert.at als Absender, sondern von noreply(a)cert.at aus. [..] Echte Rückfragen sollten weiterhin an team(a)cert.at gerichtet werden. --------------------------------------------- https://www.cert.at/de/blog/2024/7/neuer-absender-fuer-notifications ∗∗∗ Uncoordinated Vulnerability Disclosure: The Continuing Issues with CVD ∗∗∗ --------------------------------------------- On patch Tuesday last week, Microsoft released an update for CVE-2024-38112, which they said was being exploited in the wild. We at the Trend Micro Zero Day Initiative (ZDI) agree with them because that’s what we told them back in May when we detected this exploit in the wild and reported it to Microsoft. However, you may notice that no one from Trend or ZDI was acknowledged by Microsoft. This case has become a microcosm of the problems with coordinated vulnerability disclosure (CVD) as vendors push for coordinated disclosure from researchers but rarely practice any coordination regarding the fix. This lack of transparency from vendors often leaves researchers who practice CVD with more questions than answers. --------------------------------------------- https://www.thezdi.com/blog/2024/7/15/uncoordinated-vulnerability-disclosur… ∗∗∗ Microsoft Says Windows Not Impacted by regreSSHion as Second OpenSSH Bug Is Found ∗∗∗ --------------------------------------------- Microsoft confirmed last week that Windows is not affected by the vulnerability. --------------------------------------------- https://www.securityweek.com/microsoft-says-windows-not-impacted-by-regress… ∗∗∗ ClickFix Deception: A Social Engineering Tactic to Deploy Malware ∗∗∗ --------------------------------------------- The HTML file masquerades as a Word document, displaying an error prompt to deceive users. [..] In a nutshell, clicking on the “How to fix” button triggers the execution of JavaScript code that copies the PowerShell script directly onto the clipboard. [..] Once the script is pasted and executed in the PowerShell terminal, it allows the malware to infiltrate the victim’s system, potentially leading to data theft, system compromise, or further propagation of the malware. --------------------------------------------- https://www.mcafee.com/blogs/other-blogs/mcafee-labs/clickfix-deception-a-s… ∗∗∗ DNS hijacks target crypto platforms registered with Squarespace ∗∗∗ --------------------------------------------- A wave of coordinated DNS hijacking attacks targets decentralized finance (DeFi) cryptocurrency domains using the Squarespace registrar, redirecting visitors to phishing sites hosting wallet drainers. --------------------------------------------- https://www.bleepingcomputer.com/news/security/dns-hijacks-target-crypto-pl… ∗∗∗ June Windows Server updates break Microsoft 365 Defender features ∗∗∗ --------------------------------------------- Microsoft has confirmed that Windows Server updates from last months Patch Tuesday break some Microsoft 365 Defender features that use the network data reporting service. --------------------------------------------- https://www.bleepingcomputer.com/news/microsoft/june-windows-server-updates… ∗∗∗ Facebook ads for Windows desktop themes push info-stealing malware ∗∗∗ --------------------------------------------- Cybercriminals use Facebook business pages and advertisements to promote fake Windows themes that infect unsuspecting users with the SYS01 password-stealing malware. [..] While using Facebook advertisements to push information-stealing malware is not new, the social media platform's massive reach makes these campaigns a significant threat. --------------------------------------------- https://www.bleepingcomputer.com/news/security/facebook-ads-for-windows-the… ∗∗∗ Knot Resolver 6 News: DoS protection – operator’s overview ∗∗∗ --------------------------------------------- The team behind Knot Resolver, the scalable caching DNS resolver, is hard at work developing a complex solution for protecting DNS servers and other participants on the Internet alike against denial-of-service attacks. This effort is a part of the ongoing DNS4EU project, co-funded by the European Union1, which we are a proud part of. [..] As usual with projects from CZ.NIC, all of this code is also free and open source under the GPL license, so everyone is free to study and adapt it for their own exciting purposes. --------------------------------------------- https://en.blog.nic.cz/2024/07/15/knot-resolver-6-news-dos-protection-opera… ∗∗∗ 16-bit Hash Collisions in .xls Spreadsheets, (Sat, Jul 13th) ∗∗∗ --------------------------------------------- Since the hashing algorithm used for the protection of .xls files produces a 16-bit integer with its highest bit set, there are 32768 (0x8000) possible hash values (called verifier), and thus ample chance to generate hash collisions. I generated such a list, and included it in an update of my oledump plugin plugin_biff.py. --------------------------------------------- https://isc.sans.edu/diary/rss/31066 ∗∗∗ Protected OOXML Spreadsheets, (Mon, Jul 15th) ∗∗∗ --------------------------------------------- I was asked a question about the protection of an .xlsm spreadsheet [..] --------------------------------------------- https://isc.sans.edu/diary/rss/31070 ∗∗∗ CRYSTALRAY Hackers Infect Over 1,500 Victims Using Network Mapping Tool ∗∗∗ --------------------------------------------- A threat actor that was previously observed using an open-source network mapping tool has greatly expanded their operations to infect over 1,500 victims. Sysdig, which is tracking the cluster under the name CRYSTALRAY, said the activities have witnessed a tenfold surge, adding it includes "mass scanning, exploiting multiple vulnerabilities, and placing backdoors using multiple [open-source software] security tools." --------------------------------------------- https://thehackernews.com/2024/07/crystalray-hackers-infect-over-1500.html ∗∗∗ CVE-2024-38112: Void Banshee Targets Windows Users Through Zombie Internet Explorer in Zero-Day Attacks ∗∗∗ --------------------------------------------- Our threat hunters discovered CVE-2024-38112, which was used as a zero-day by APT group Void Banshee, to access and execute files through the disabled Internet Explorer using MSHTML. We promptly identified and reported this zero-day vulnerability to Microsoft, and it has been patched. --------------------------------------------- https://www.trendmicro.com/en_us/research/24/g/CVE-2024-38112-void-banshee.… ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Monday ∗∗∗ --------------------------------------------- Security updates have been issued by Fedora (cups, krb5, pgadmin4, python3.6, and yarnpkg), Mageia (freeradius, kernel, kmod-xtables-addons, kmod-virtualbox, and dwarves, kernel-linus, and squid), Red Hat (ghostscript, kernel, and less), SUSE (avahi, c-ares, cairo, cups, fdo-client, gdk-pixbuf, git, libarchive, openvswitch3, podman, polkit, python-black, python-Jinja2, python-urllib3, skopeo, squashfs, tiff, traceroute, and wget), and Ubuntu (linux, linux-azure, linux-azure-5.4, linux-bluefield, linux-gcp, linux-gcp-5.4, linux-gkeop, linux-ibm, linux-ibm-5.4, linux-kvm). --------------------------------------------- https://lwn.net/Articles/982029/ ∗∗∗ Admin-Lücke bedroht Palo Alto Networks Migration-Tool Expedition ∗∗∗ --------------------------------------------- Verschiedene Cybersicherheitsprodukte von Palo Alto Networks sind verwundbar.

Es geht hier um ernsthafte Bandbreiten und Packets/Sekunde: kein Wunder, wenn es die Angreifer geschafft haben, gute angebundene Router für ihre Zwecke einzuspannen.

The topic was the relationship between cyber security and law enforcement: how do CSIRTs and the police / public prosecutors cooperate, what works here and where are the fault lines in this collaboration. As the moderator, I wasn’t in the position to really present my own view on some of the issues, so I’m using this blogpost to document my thinking regarding the CSIRT/LE division of labour. From that starting point, this text kind of turned into a rant on what’s wrong with IT Security. --------------------------------------------- https://www.cert.at/en/blog/2024/7/csirt-le-military ∗∗∗ NIS2 - Implementing Acts ∗∗∗ --------------------------------------------- Es liegen endlich Entwürfe für die Implementing Acts zur NIS 2 Richtline vor, die Umsetzungsdetails regeln werden. Genauer gesagt: es geht um Kriterien, wann ein Vorfall meldepflichtig wird und Maßnahmen zum Risikomanagement. Seitens der EU gibt es ein öffentliches Konsultationsverfahren dazu, das bis zum 25. Juli offen ist. Die Entwürfe sind auch über diese Webseite abrufbar. --------------------------------------------- https://www.cert.at/de/blog/2024/6/nis2-implementing-acts ∗∗∗ Vorsicht vor gefälschten Gewinnspielen zur UEFA EURO 2024 ∗∗∗ --------------------------------------------- Kriminelle verbreiten per E-Mail gefälschte Gewinnspiele zur UEFA EURO 2024.
