It’s considered one of the better sandboxing mechanisms deployed at scale without requiring elevated privileges to function. For all the good, it does have its weaknesses. The main one being the sandbox’s implementation is reliant on the security of the Windows OS. --------------------------------------------- https://googleprojectzero.blogspot.com/2020/04/you-wont-believe-what-this-o… ∗∗∗ New iPhone Zero-Day Discovered ∗∗∗ --------------------------------------------- Last year, ZecOps discovered two iPhone zero-day exploits. They will be patched in the next iOS release: Avraham declined to disclose many details about who the targets were, and did not say whether they lost any data as a result of the attacks, but said "we were a bit surprised about who was targeted." --------------------------------------------- https://www.schneier.com/blog/archives/2020/04/new_iphone_zero.html ∗∗∗ NSA, ASD Release Guidance for Mitigating Web Shell Malware ∗∗∗ --------------------------------------------- The U.S. National Security Agency (NSA) and the Australian Signals Directorate (ASD) have jointly released a Cybersecurity Information Sheet (CSI) on mitigating web shell malware. Malicious cyber actors are increasingly deploying web shell malware on victim web servers to execute arbitrary system commands. By deploying web shell malware, cyber attackers can gain persistent access to compromised networks. --------------------------------------------- https://www.us-cert.gov/ncas/current-activity/2020/04/22/nsa-asd-release-gu… ∗∗∗ Achtung vor Shops mit service6(a)vinayotap.com E-Mail-Adressen ∗∗∗ --------------------------------------------- Derzeit melden LeserInnen der Watchlist Internet vermehrt neue Fake-Shops, die vor allem eines gemeinsam haben: Sie verweisen alle auf die E-Mail-Adresse --------------------------------------------- https://www.watchlist-internet.at/news/achtung-vor-shops-mit-service6vinayo… ===================== = Vulnerabilities = ===================== ∗∗∗ Microsoft Issues Out-Of-Band Security Update For Office, Paint 3D ∗∗∗ --------------------------------------------- The flaws exist in Autodesks FBX library, integrated in Microsofts Office, Office 365 ProPlus and Paint 3D applications. --------------------------------------------- https://threatpost.com/microsoft-issues-out-of-band-security-update-for-off… ∗∗∗ Zero-Day-Lücken in IBM Data Risk Manager - Forscher-Report ignoriert ∗∗∗ --------------------------------------------- Sicherheitsforscher haben im Überwachungstool IBM Data Risk Manager vier Lücken entdeckt - drei gelten als kritisch.

In February I received a DM via Twitter from Liisa at SpectX regarding my interest in checking out SpectX. Never one to shy away from a tool review offer, I accepted. SpectX, available in a free, community desktop version, is a log parser and query engine that enables you to investigate incidents via log files from multiple sources such as log servers, AWS, Azure, Google Storage, Hadoop, ELK and SQL-databases. --------------------------------------------- https://isc.sans.edu/diary/rss/26040 ∗∗∗ Exposed Redis Instances Abused for Remote Code Execution, Cryptocurrency Mining ∗∗∗ --------------------------------------------- Recently, we wrote an article about more than 8,000 unsecured Redis instances found in the cloud. In this article, we expound on how these instances can be abused to perform remote code execution (RCE), as demonstrated by malware samples captured in the wild. --------------------------------------------- http://feeds.trendmicro.com/~r/Anti-MalwareBlog/~3/l3TOyRDK1yA/ ∗∗∗ Grouping Linux IoT Malware Samples With Trend Micro ELF Hash ∗∗∗ --------------------------------------------- We created Trend Micro ELF Hash (telfhash), an open-source clustering algorithm that effectively clusters Linux IoT malware created using ELF files. --------------------------------------------- http://feeds.trendmicro.com/~r/Anti-MalwareBlog/~3/tFHtqxisecc/ ∗∗∗ Kerberos Tickets on Linux Red Teams ∗∗∗ --------------------------------------------- At FireEye Mandiant, we conduct numerous red team engagements within Windows Active Directory environments. Consequently, we frequently encounter Linux systems integrated within Active Directory environments. Compromising an individual domain-joined Linux system can provide useful data on its own, but the best value is obtaining data, such as Kerberos tickets, that will facilitate lateral movement techniques. --------------------------------------------- http://www.fireeye.com/blog/threat-research/2020/04/kerberos-tickets-on-lin… ∗∗∗ Unsichere Deserialisierung gefährdet Steam-Spiele ∗∗∗ --------------------------------------------- Viele Videospiele, die .Net oder Unity verwenden, sind angreifbar und führen Schadcode aus.

And 73% of those SMBs that have been the targets of ransomware attacks actually have paid a ransom, Infrascale reveals. Yet, more than a quarter of the total SMB survey group said they lack a plan to mitigate a ransomware attack. --------------------------------------------- https://www.helpnetsecurity.com/2020/04/21/paying-ransom/ ∗∗∗ BSI aktualisiert den Mindeststandard TLS ∗∗∗ --------------------------------------------- Das Bundesamt für Sicherheit in der Informationstechnik (BSI) hat zum 9.

Nach einer Registrierung erhalten Sie jedoch eine Zahlungsaufforderung über 395,88 Euro. Wird diese ignoriert, folgen meist weitere Zahlungsaufforderungen und Mahnungen von vermeintlichen Inkassobüros. Überweisen Sie kein Geld und antworten Sie auch nicht!
