Would You Like Paper Or Silicon for Your Data Breach? About the cover There are eight pendulums on the cover. Each pendulum represents one of the new patterns in the DBIR. The weight of the pendulum represents how often the pattern occurs. The length of the pendulum is how often they are breaches, as opposed to simply incidents. Just like in security, it’s difficult to predict where they’ll be in the future.

  • Advanced Persistent Threats
    THREAT RESEARCH Defending Against Advanced Persistent Threats Introduction As the name “Advanced” suggests, APT (advanced persistent threat) is one of the most sophisticated and organized forms of network attacks that keep cybersecurity professionals up at night. Unlike many hit & run traditional cyberattacks, an APT is carried out over a prolonged period of time by skilled threat actors who strategize multi-staged campaigns against their targets, employing clandestine tools & techniques such as Remote Administration Tools (RAT), Toolkits, Backdoor Trojans, Social Engineering, DNS Tunneling etc. These experienced cybercriminals are mostly backed & well-funded by nation states and corporation-backed organizations to specifi cally target high value organizations with the following objectives in mind: a Theft of Intellectual Property & classifi ed data i.e. Cyber Espionage a Access to critical & sensitive communications a Access to credentials of critical systems a Sabotage or exfi ltration of databases a Theft of Personal Identifi able Information (PII) a Access to critical infrastructure to perform internal reconnaissance To achieve the above goals, APT Groups use novel techniques to obfuscate their actions and easily bypass traditional security barriers that are not advancing at the same rate as the sophisticated attack patterns of cybercriminals. To understand the evolved behavioral pattern of APT Groups in the year 2020, a review of their latest activities revealed interesting developments and a few groundbreaking events¹: a Southeast Asia

Watch this space for the August feature! August 1st is acknowledged across the globe as World Wide Web Day! World Wide Web Day, marks the birth of the Web in August 1990 at the Europe Laboratory for Particle Physics (CERN) in Switzerland. Tim Berners-Lee and Robert Cailliau developed a prototype Web browser and introduced Hypertext Markup Language, HTML. The first ever website was published on August 6, 1991 and served up a page explaining the World Wide Web project and giving information on how users could setup a web server and how to create their own websites and web pages, as well as how they could search the web for information. The URL for the first ever web page put up on the first ever website was http://info.cern.ch/hypertext/WWW/TheProject.html The World Wide Web ('WWW' or simply the 'Web') is a global information medium which users can read and write via computers connected to the Internet. The term [web] is often mistakenly used as a synonym for the Internet itself, but the Web is a service that operates over the Internet, just as e-mail also does.

For years, over 95% of businesses have unknowingly hosted compromised PCs within their corporate networks, and that has not changed. During our assessment, we identified all types of threat actors compromising our customers’ networks, including suspected nation-state-backed actors looking to conduct cyber espionage, cybercriminals and hacktivists looking to make a statement. This Regional Advanced Threat Report for EMEA provides an overview of the advanced targeted threats against computer networks that FireEye discovered during the second half of 2015. It is a follow-up to the Advanced Threat Report for EMEA 1H2015. SPECIAL REPORT / REGIONAL ADVANCED THREAT REPORT 3 Turkey, Spain, Israel, Luxembourg and Germany are the countries most targeted with advanced attacks. Motivated by many objectives, threat actors’ capabilities are evolving to be able to steal personal data and business strategies, gain a competitive advantage or degrade operational reliability. This report summarizes 2H2015 data gleaned from the FireEye Dynamic Threat Intelligence (DTI) cloud. The threat landscape has undergone dramatic changes between the first and second half of 2015.

  • CYBERSECURITY: the Greatest Hurdle of the 2016 Olympic Games INTRODUCTION
    CYBERSECURITY: The Greatest Hurdle of the 2016 Olympic Games INTRODUCTION 1 Every two years, the world turns its collective attention to an event that has come to epitomize “International Olympic Committee Marketing Report: London 2012,” a rare moment in international co-existence. Underneath jerseys and face paint indicating Olympic Committee, 2012. Link national allegiance is an appreciation for talent and hard work, regardless of state origin. Amid the fiercest competition in the world emerges a sense of humanistic unity in both athletics and beyond. For seventeen days this August, Olympic fervor will begin all over again. Preparing for an event that attracts 7.5 million ticketed spectators and 3.5 billion television viewers1 is no small feat for any city, even for highly industrialized hosts such as London and Beijing. As the first South American country to host an Olympic Games, Brazil carries the reputation of an entire region on its shoulders. Amid this pressure, Brazil is also faced with a host of internal issues. Rampant corruption, economic collapse, and the Zika virus threaten to launch Brazil into utter chaos. Amid these immediate and pressing challenges, however, lies a more covert concern. Brazil’s insufficient cybersecurity infrastructure, coupled with the world’s attention, make the 2016 Rio de Janeiro Olympic Games a perfect target for cybercriminals. graquantum.com infograquantum.com This paper explores Brazil’s existing cyber landscape, including its status both regionally and globally. It will begin by examining the history of cybercrime in Brazil and its existing Internet infrastructure. It will then contextualize Brazil’s unique cyber landscape in the context of the Olympic Games, including comparisons with previous and future host countries, and efforts to secure Brazil’s cyber architecture specific to the games.

Any other reproduction or transmission 2018 © NATO CCD COE Publications, Tallinn requires prior written permission by NATO CCD COE. Aladdin’s Lamp: The Theft and Re-weaponization of Malicious Code Kārlis Podiņš Kenneth Geers CERT Latvia Comodo Group Riga, Latvia Toronto, Canada Abstract: Global superpowers do not have a monopoly on cyber warfare. Software thieves can steal malware written by more advanced coders and hackers, modify it, and reuse it for their own purposes. Smaller nations and even non-state actors can bypass the most technically challenging aspects of a computer network operation – vulnerability discovery and exploit development – to quickly acquire world-class cyber weapons. This paper is in two parts. First, it describes the technical aspects of malware re-weaponization, specifically the replacement of an existing payload and/or command-and-control (C2) architecture. Second, it explores the implications of this phenomenon and its ramifications for a range of strategic concerns including weapons proliferation, attack attribution, the fog of war, false flag operations, international diplomacy, and strategic miscalculation. And as with Aladdin’s magic lamp, many malware thieves discover that obtaining a powerful new weapon carries with it risks as well as rewards. Keywords: malware, cyberwar, re-weaponization, false flag, attribution 1.

It works like this: Individuals who connect to the Internet receive a request for a fake update to a popular software package such as Adobe Flash, Google Toolbar or Windows Messenger. The installation files include legitimate software but also secretly harbour the DarkHotel code. Once the target approves the download with a single click, the malicious DarkHotel code goes to work, employing a number of different malware, including the following: DarkHotel Hackers Target Bosses in Hotels Keyloggers monitor users’ activity by recording and transmitting their keyboard Think your company’s executives and mouse presses. are safe in their hotel rooms?
