Has been the target for Nation-sponsored hackers for a long time (Equation Group) 3. More than 400,000 Exchange servers exposed on the Internet according to our survey Exchange Security in the Past Years • Most bugs are based on known attack vectors but there are still several notable bugs: 1. EnglishmansDentist from Equation Group: • Recap: A only practical and public pre-auth RCE in the Exchange history. Unfortunately, the arsenal only works on an ancient Exchange Server 2003 2. CVE-2020-0688 Hardcoded MachineKey from anonymous working with ZDI: • Recap: A classic .NET deserialization bug due to a hardcoded cryptography key. This is also a hint shows Microsoft Exchange is lacking of security reviews Our Works • We focus on the Exchange architecture and discover a new attack surface that no one proposed before. -

All Rights Reserved. 3 Introduction It was in 1974 that the first DDoS attack was launched when David Dennis—a 13-year-old learned about a new command that could be run on CERL’s PLATO terminals. Called “external” or “ext,” the command could cause the terminal to lock up—requiring a shutdown and power- on to regain functionality. He tested his knowledge which forced several users to power off simultaneously. In the 45 years since its inception, this form of attack has gained the status of the most persistent and damaging of all cyber-attacks. The next milestone in DDoS attacks occurred in August 1999, when a hacker used a tool called `Trinoo’ or `Trin00’, to disable the University of Minnesota’s computer network for more than two days. Trinoo is one of the first publicly available DDoS programs and a ground-setter for other widely available DDoS tools that would emerge in the future. Using a compromised host, the attacker executes automated processes to make a list of vulnerable machines. -

Cryptographic Software: Vulnerabilities in Implementations 1
Pobrane z czasopisma Annales AI- Informatica http://ai.annales.umcs.pl Data: 03/10/2021 00:10:27 Annales UMCS Informatica AI XI, 4 (2011) 1–10 DOI: 10.2478/v10065-011-0030-7 Cryptographic software: vulnerabilities in implementations Michał Łuczaj1∗ 1Institute of Telecommunications, Warsaw University of Technology Poland Abstract – Security and cryptographic applications or libraries, just as any other generic software products may be affected by flaws introduced during the implementation process. No matter how much scrutiny security protocols have undergone, it is — as always — the weakest link that holds everything together to makes products secure. In this paper I take a closer look at problems usually resulting from a simple human made mistakes, misunderstanding of algorithm details or a plain lack of experience with tools and environment. In other words: everything that can and will happen during software development but in the fragile context of cryptography. UMCS1 Introduction I begin with a brief introduction of typical mistakes and oversights that can be made during program implementation in one of the most popular programming languages, C[1]. I also explain the concept of exploitable memory corruption, how critical it is and where it leads from the attacker’s point of view. A set of real-world examples is given. Some well known previously disclosed vulner- abilities are brought to illustrate how a flaw (sometimes even an innocent looking) can fatally injune security of the whole protocol, algorithm. There is much to discuss as failed attempts at implementing cryptographic primitives — or making use of cryptog- raphy in general — range broadly. -
