Spoofing: Neue DNS-Angriffsmethode entdeckt

(13. November 2020)

Nachdem der Quellport de-randomisiert worden sei, sei es möglich gewesen, eine böswillige IP-Adresse einzuschleusen und so erfolgreich einen DNS-Cache-Poisoning-Angriff durchzuführen. Die Details haben die Forscher im Paper „DNS Cache Poisoning Attack Reloaded: Revolutions with Side Channels“ publiziert.

Weitere Experimente unter realistischen Serverkonfigurationen und Netzwerkbedingungen würden zudem zeigen, dass ihre grundlegende Methode leicht an das gesamte DNS-System angepasst werden könnte.

SAD Reality for DNS

The researchers determined that 35% of open resolvers are open to the attack, as well as four of six home routers made by well-known brands.

They also found that 12 of 14 popular public resolvers (now 11—Cloudflare says they’ve corrected their systems) are susceptible. Even a patched DNS server could be made vulnerable by an unpatched or misconfigured NAT gateway.

Their 19-page paper on the exploit includes lists of devices and services tested. They have since set up a SAD DNS website featuring a Q&A and a tool that anyone can use to determine whether their DNS is vulnerable.

The flaw is being tracked as CVE-2020-25705, and affects Linux 3.18 – 5.10, Windows Server 2019 version 1809 and newer, macOS 10.15 and newer, and FreeBSD 12.1.0 and newer. The researchers did not test earlier versions of the listed operating system.

SynAck ransomware circumvents antivirus software through Doppelgänging technique

(8.5.2018) Process Doppelgänging was first revealed by enSilo researchers at Black Hat Europe in December last year.

The attack technique targets the Microsoft Windows operating system and is designed to circumvent traditional security software and antivirus solutions by exploiting how they interact with memory processes.

CPU Utilization Is Wrong on PCs, and Getting Worse Every Year

Microsoft’s Windows 7 Meltdown update granted access to all data in memory

“Windows 7 already did the hard work of mapping in the required memory into every running process,” Frisk states. “Exploitation was just a matter of read and write to already mapped in-process virtual memory. No fancy APIs or system calls required — just standard read and write!”
