Security Now! #664 - 05-22-18 Spectreng Revealed
Security Now! #664 - 05-22-18 SpectreNG Revealed This week on Security Now! This week we examine the recent flaws discovered in the secure Signal messaging app for desktops, the rise in DNS router hijacking, another seriously flawed consumer router family, Microsoft Spectre patches for Win10's April 2018 feature update, the threat of voice assistant spoofing attacks, the evolving security of HTTP, still more new trouble with GPON routers, Facebook's Android app mistake, BMW's 14 security flaws and some fun miscellany. Then we examine the news of the next-generation of Spectre processor speculation flaws and what they mean for us. Our Picture of the Week Security News Update your Signal Desktop Apps for Windows & Linux A few weeks ago, Argentinian security researchers discovered a severe vulnerability in the Signal messaging app for Windows and Linux desktops that allows remote attackers to execute malicious code on recipient systems simply by sending a message—without requiring any user interaction. The vulnerability was accidentally discovered while researchers–amond them Juliano Rizzo–were chatting on Signal messenger and one of them shared a link of a vulnerable site with an XSS payload in its URL. However, the XSS payload unexpectedly got executed on the Signal desktop app!! (Juliano Rizzo was on the beach when the BEAST and CRIME attacks occurred to him.) After analyzing the scope of this issue by testing multiple XSS payloads, they found that the vulnerability resides in the function responsible for handling shared links, allowing attackers to inject user-defined HTML/JavaScript code via iFrame, image, video and audio tags. -
Internet of Things Botnet Detection Approaches: Analysis and Recommendations for Future Research

At the same time, it has resulted in an increase in cybersecurity risks due to the lack of security for IoT devices. IoT botnets, for instance, have become a critical threat; however, systematic and comprehensive studies analyzing the importance of botnet detection methods are limited in the IoT environment. Thus, this study aimed to identify, assess and provide a thoroughly review of experimental works on the research relevant to the detection of IoT botnets. To accomplish this goal, a systematic literature review (SLR), an effective method, was applied for gathering and critically reviewing research papers. This work employed three research questions on the detection methods used to detect IoT botnets, the botnet phases and the different malicious activity scenarios. The authors analyzed the nominated research and the key methods related to them. The detection Citation: Wazzan, M.; Algazzawi, D.; methods have been classified based on the techniques used, and the authors investigated the botnet Bamasaq, O.; Albeshri, A.; Cheng, L. -
Technical Brief P2P Iot Botnets Clean AC Font
Uncleanable and Unkillable: The Evolution of IoT Botnets Through P2P Networking Technical Brief By Stephen Hilt, Robert McArdle, Fernando Merces, Mayra Rosario, and David Sancho Introduction Peer-to-peer (P2P) networking is a way for computers to connect to one another without the need for a central server. It was originally invented for file sharing, with BitTorrent being the most famous P2P implementation. Decentralized file-sharing systems built on P2P networking have stood the test of time. Even though they have been used to share illegal pirated content for over 20 years, authorities have not been able to put a stop to these systems. Of course, malicious actors have used it for malware for quite a long time as well. Being able to create and manage botnets without the need for a central server is a powerful capability, mostly because law enforcement and security companies typically take down criminal servers. And since a P2P botnet does not need a central command-and-control (C&C) server, it is much more difficult to take down. From the point of view of defenders, this is the scariest problem presented by P2P botnets: If they cannot be taken down centrally, the only option available would be to disinfect each of the bot clients separately. Since computers communicate only with their own peers, the good guys would need to clean all the members one by one for a botnet to disappear. Originally, P2P botnets were implemented in Windows, but developers of internet-of-things (IoT) botnets do have a tendency to start incorporating this feature into their creations. -
Reporting, and General Mentions Seem to Be in Decline
CYBER THREAT ANALYSIS Return to Normalcy: False Flags and the Decline of International Hacktivism By Insikt Group® CTA-2019-0821 CYBER THREAT ANALYSIS Groups with the trappings of hacktivism have recently dumped Russian and Iranian state security organization records online, although neither have proclaimed themselves to be hacktivists. In addition, hacktivism has taken a back seat in news reporting, and general mentions seem to be in decline. Insikt Group utilized the Recorded FutureⓇ Platform and reports of historical hacktivism events to analyze the shifting targets and players in the hacktivism space. The target audience of this research includes security practitioners whose enterprises may be targets for hacktivism. Executive Summary Hacktivism often brings to mind a loose collective of individuals globally that band together to achieve a common goal. However, Insikt Group research demonstrates that this is a misleading assumption; the hacktivist landscape has consistently included actors reacting to regional events, and has also involved states operating under the guise of hacktivism to achieve geopolitical goals. In the last 10 years, the number of large-scale, international hacking operations most commonly associated with hacktivism has risen astronomically, only to fall off just as dramatically after 2015 and 2016. This constitutes a return to normalcy, in which hacktivist groups are usually small sets of regional actors targeting specific organizations to protest regional events, or nation-state groups operating under the guise of hacktivism. Attack vectors used by hacktivist groups have remained largely consistent from 2010 to 2019, and tooling has assisted actors to conduct larger-scale attacks. However, company defenses have also become significantly better in the last decade, which has likely contributed to the decline in successful hacktivist operations. -
Mobilní Telefony V Linuxu
Michal Čihař <[email protected]> Mobilní telefony v Linuxu – Gammu a Wammu Mobilní telefon má dnes téměř každý a přístup k mnoha informacím, které v něm dnes mohou být uloženy z počítače se jeví jako logický požadavek. Pro Windows nám většinou výrobce poskytne více či méně kvalitní program, ale pod ostatními systémy si obvykle musíme poradit pomocí jiných nástrojů. V této přednášce se dozvíte jak je na tom v tomto ohledu Linux. Připojení telefonu Telefonem můžeme připojit mnoha způsoby, a každý z nich má své výhody i nevýhody. Hlavním rozdílem je jestli se budeme připojovat prostřednictvím kabelu, nebo využijeme bezdrátového připojení. První telefony, které umožňovaly připojení k počítači, používaly sériový kabel. Toto připojení bylo bezproblémové, ale jak s postupem doby začaly z počítačů mizet sériové porty, výrobci od něho začali ustupovat. V dnešní době je v podstatě nahrazeno různými USB kabely, které dost často opět obsahují konvertor USB/sériový port. Takže stále používáme tu samou technologii, jen k tomu používáme řádově dražší kabel. U těchto kabelů jsou občas problémy s ovladači, protože standardizace do této oblasti ještě nedorazila. Nicméně většina z nich vám bude na Linuxu fungovat. Z bezdrátových připojení je zdaleka nejrozšířenější Bluetooth a IrDA. IrDA pracuje v infračerveném pásmu a má relativně krátký dosah. Oproti tomu Bluetooth pracující v mikrovlnném pásmu (stejné jako WiFi) má dosah větší. Z toho ovšem plynou i možná bezpečnostní rizika. Toto připojení je všesměrové a tudíž kdokoliv, kdo se nachází ve vašem okolí se může pokusit k telefonu připojit. A nutno podotknout, že díky špatnému zabezpečení nebo chybám v implementaci v telefonu se mu to může zdárně podařit. -
Week 3 Reading Assignment: Understanding the Mirai Botnet
Week 3 Reading Assignment: Understanding the Mirai Botnet Discussion Summary Questions Raised in the Paper: • How could an attacker mine the data available through Spectre attack? • Since the Spectre vulnerability is harder to exploit, it would be interesting to know if this attack has been successfully performed outside of a lab? • Is it possible that Spectre vulnerability is already being taken advantage of, and no one is aware? • What other security problems are embedded in our computers, that we don’t know of? • The released Meltdown and Spectre patches only address issues raised by researches. However, there is a higher probability that one can possibly devise another cache mechanism to trick CPU into reading memory map; as the mechanism is built into the physical memory space. What about those vulnerabilities? Main Take-Aways: About the Attacks: • Meltdown and Spectre vulnerabilities are among the best discoveries in computer science if not the most important • Both vulnerabilities take advantage of a process called speculative execution, where the processor can execute some code in advance and out of order and cache the output, expecting to use that output for the next step in the process. • Using Kernel Page Table Isolation (KPTI) technique, which stops speculation execution by removing mapping kernel into a program when running user space, is one of the current known mitigation techniques to prevent Meltdown. • Noticeable difference between Meltdown and Spectre is the fact that Spectre does not use privilege escalation, thus making the Spectre vulnerability more sophisticated. • “I do not personally consider this a CPU design flaw like Meltdown per se. -

It combines politics, the Internet, and other elements. Let’s start with the political. Activism, a political movement emphasising direct action, is the inspiration for hacktivism. Think of Greenpeace activists who go to sea to disrupt whaling campaigns. Think of the many demonstrators who protested against human rights violations in China by trying to put out the Olympic flame during its world tour in 2008. Think of the thousands of activists who responded to the Adbusters call in July 2011 to peacefully occupy a New York City park as part of Occupy Wall Street. Adding the online activity of hacking (with both good and bad connotations) to political activism gives us hacktivism. One source claims this term was first used in an article on the filmmaker Shu Lea Cheang; the article was written by Jason Sack and published in InfoNation in 1995. -
