Highlighting that better security measures with improved time-to-patch rate is helping to improve vulnerability severity ratings in 2014. o HPE had the most verified vulnerabilities reported with 317 proving the veracity of the HPE Tipping Point contributor program. • Hewlett-Packard Enterprise (HPE) found 150 critical and high-severity vulnerabilities (vulnerabilities are labeled critical severity if they have a common vulnerability scoring system (CVSS) base score of 10.0 and rated high severity with a CVSS base score of 9.9 – 7.0). All other disclosing companies accounted for 163 high-severity vulnerabilities. • Buffer overflow errors were the most common vulnerability flaw in 2013 and remained so in 2014. HPE found 125 incidents of buffer overflow errors in 2014, followed by Verisign iDefense, which found 14 vulnerabilities related to buffer overflow errors. • In 2014, the top six applications with the most vulnerabilities were Microsoft Internet Explorer, Oracle Java Runtime Environment, Microsoft Windows, Adobe Flash Player, Apple QuickTime, and Adobe Reader. • Frost & Sullivan counted 197 vulnerabilities (or 27.1% of all vulnerabilities) directly related to Web applications. • SCADA vulnerabilities increased from 25 in 2013 to 33 in 2014. • Researchers are looking at more than just network-attached endpoints for vulnerabilities. Web applications and browsers, malware, mobile malware, SCADA, and the Internet of Things are increasingly scrutinized. • Legacy systems and software that are no longer supported are a major concern for IT departments. On April 14, 2014, Microsoft discontinued its technical support for Windows XP on most devices and all PCs. There are an estimated 300 million PCs actively running on XP.

NFDF-74 9 Market Overview NFDF-74 10 Research Objectives Primary Objective Secondary Objectives To acquire, record, and derive • To identify and promote prolific an insightful understanding reporters of vulnerabilities of Public Vulnerability Research from reliable vulnerability • To highlight and emphasize the vendors and research strongest work produced by laboratories in 2014 companies engaging in public vulnerability research reports • To analyze the gathered vulnerability data for trends and common factors Source: Frost & Sullivan analysis. NFDF-74 11 Market Overview • The following is both a study about software vulnerabilities and the companies that publicly disclose vulnerabilities. • A security vulnerability is any error in an IT system that can be exploited by an attacker to compromise the confidentiality or integrity of a system or to deny legitimate user access to a system. Other industry terms for security vulnerabilities include “software bug” and “flaw.” • In the past, the process by which the analysis of vulnerabilities was shared with third parties was subject to much debate, as full disclosure is the practice of making the details of security vulnerabilities public. o There is much debate in making vulnerabilities public because keeping vulnerabilities secret or not public keeps them out of the hands of hackers, but this assumes that hackers can’t discover vulnerabilities on their own. From the organization side, keeping vulnerabilities secret assumes organizations will spend time and money fixing secret vulnerabilities . Both assumptions have proven to be false. o Hackers have proven to be quite adept at discovering secret vulnerabilities. Full disclosure forces organizations to routinely patch their systems. • Organizations tend to treat vulnerabilities less as a software problem and more as a public relations (PR) problem. This is where full disclosure comes into play by making the PR problem more acute, organizations are then quick to patch vulnerabilities. o Naturally organizations receiving negative PR every time a vulnerability is made public quickly release a patch fixing the vulnerability in order to minimize the impact of negative PR. • Full disclosure of vulnerabilities helped shape the standardization of how vulnerabilities are tracked, managed and stored. Source: Frost & Sullivan analysis. NFDF-74 12 Market Overview (Continued) • Since 1999, the MITRE Corporation is responsible for certification and accreditation of the Common Vulnerabilities and Exposures (CVE), enabling standardization of how public vulnerabilities are tracked, managed and stored. • The MITRE Corporation (a not-for-profit company that operates multiple federally funded research and development centers (FFRDCs) that provide innovative, practical solutions for some of the United States critical challenges) operates the National Cyber Security FFRDC to enhance cyber security and protect national information systems. o Funding for the MITRE Corporation comes from the National Cyber Security Division of the United States Department of Homeland Security. • The MITRE documentation defines CVE identifiers (also called CVE numbers, CVE-IDs and CVEs) as unique common identifiers for publicly known information-security vulnerabilities in publically released software packages. • In other words, the CVE is a dictionary of common names for publicly known information security vulnerabilities. CVE’s common identifiers make it easier to share data across separate network security databases and tools and provide a baseline for evaluating the coverage of an organization’s security tools enabling a quick and accurate assessment of how to remediate vulnerabilities. Source: Frost & Sullivan analysis. NFDF-74 13 Market Overview (Continued) • CVEs (vulnerabilities) are assigned by a CVE Numbering Authority (CNA); there are three primary types of CVE number assignments: o The MITRE Corporation functions as editor and primary CNA. o Various CNAs assign CVE entries for their own products (i.e. Microsoft, HPE, Oracle, etc.). o Red Hat (multinational software company

See Also: Live Webinar | Scaling Security at the Internet Edge with Stateless Technology Since at least 2016, hacked websites have targeted zero-day flaws in the latest versions of Apple iOS to surreptitiously hack iPhones, new research from Google shows. The attack campaign has been revealed by Google's Project Zero team, which searches for zero- day flaws. It says the attack campaign was used to infect iOS devices with an implant - aka malware - that could steal private data, including photos and messages in Telegram, iMessages and Gmail, as well as send GPS data to a command-and-control server for tracking users in real time, provided they're online. "Earlier this year Google's Threat Analysis Group discovered a small collection of hacked websites. The hacked sites were being used in indiscriminate watering hole attacks against their visitors, using iPhone 0-day," Ian Beer of the Project Zero team says in a blog post published Thursday. "There was no target discrimination; simply visiting the hacked site was enough for the exploit server to attack your device, and if it was successful, install a monitoring implant," he says. "We estimate that these sites receive thousands of visitors per week." Google's test of the implant - malware - installed by the websites found that it could exfiltrate numerous types of personal data, including iMessages (Source: Google Project Zero) Apple did not immediately respond to a request for comment.

XNU • All systems deploy a same hybrid kernel structure called XNU. • There are cases that kernel vulnerabilities have been used to escalate the privileges of attackers and get full control of the system (hence jailbreak the device). • Accordingly, Apple has deployed multiple security mechanisms that make the exploitation of the device harder. Mitigation - DEP/KASLR • Apple deployed Data Execution Prevention (DEP) and Kernel Address Space Layout Randomization (KASLR) from iOS 6 and macOS 10.8. • DEP enables the system to mark relevant pages of memory as non-executable to prevent code injection attack. To break the DEP protection, code-reuse attacks (e.g., ROP) were proposed. • To make these addresses hard to predict, KASLR memory protection randomizes the locations of various memory segments. To bypass KASLR, attackers usually need to leverage information leakage bugs. Mitigation - Freelist Randomization • In previous XNU, the freelist that contains all the freed kernel objects inside a zone uses the LIFO (last-in-first-out) policy.

The spreader was apparently built by someone with "more advanced skills" than those that had created the original Mirai malware. This, Kaspersky Lab says, has "worrying implications for the future use and targets of Mirai-based attacks." It is richer and more robust than the original Mirai codebase, even though many of its components are "several years old." Its spreading capabilities are limited, as it can only deliver from an infected Windows host to a vulnerable Linux-powered IoT device. Even that -- if it can brute-force a remote telnet. It was also said that the author is likely Chinese- speaking, more experienced, but probably new to Mirai.

  • What the Experts Are Saying About Meltdown and Spectre
    What the experts are saying about Meltdown and Spectre The start of 2018 has been nothing short of exciting for the cybersecurity industry after Google Project Zero's infamous report on two existing CPU bugs. Spectre and Meltdown, two major processor flaws discovered in Intel, AMD, and ARM processors, allow attackers to access sensitive data that is handled by the CPU. While there are number of articles, blogs, white papers, and e-books available on these processor bugs, ManageEngine is bringing you this vendor-neutral digest on leading IT security and cybersecurity researchers' thoughts and advice on Meltdown and Spectre. Hear what the experts have to say on how these flaws can impact businesses, and what IT professionals need to do to mitigate Meltdown and Spectre. Harjit Dhaliwal (Microsoft MVP, senior systems administrator) If you've been closely following the news, especially news related to technology, then you're probably already aware of the Meltdown and Spectre security vulnerabilities, which were disclosed at the beginning of this year. You can read more details about these flaws and how they work on Google’s Project Zero. Basically, the flaws exploits what is technically a feature of modern processors to allow faster processing computation known as speculative execution, which is when a processor guesses your next operation based on previously cached iterations before it even happens. Typically, programs are not permitted to read or access data from other programs, however malicious attackers could take advantage and exploit the sensitive information stored in your memory, including passwords, banking information, and much more. Security researchers have revealed that nearly every computer chip manufactured in the last 20 years contains this fundamental security flaw, which affects personal computers, servers, mobile devices, and cloud computing.

  • Meltdown and Spectre Meltdown and Spectre Vulnerabilities in Modern Computers Leak Passwords and Sensitive Data
    6/17/2019 Meltdown and Spectre Meltdown and Spectre Vulnerabilities in modern computers leak passwords and sensitive data. Meltdown and Spectre exploit critical vulnerabilities in modern processors (The main part of every computer). These hardware vulnerabilities allow programs to steal data which is currently processed on the computer. While programs are typically not permitted to read data from other programs, a malicious program can exploit Meltdown and Spectre to get hold of secrets stored in the memory of other running programs. This might include your passwords stored in a password manager or browser, your personal photos, emails, instant messages and even business-critical documents. Meltdown and Spectre work on personal computers, mobile devices, and in the cloud. Depending on the cloud provider's infrastructure, it might be possible to steal data from other customers. Meltdown Meltdown breaks the most fundamental isolation between user applications and the operating system. This attack allows a program to access the memory, and thus also the secrets, of other programs and the operating system. https://meltdownattack.com 1/9 6/17/2019 Meltdown and Spectre If your computer has a vulnerable processor and runs an unpatched operating system, it is not safe to work with sensitive information without the chance of leaking the information. This applies both to personal computers as well as cloud infrastructure. Luckily, there are software patches against Meltdown. Meltdown Paper Cite arXiv Spectre Spectre breaks the isolation between different applications. It allows an attacker to trick error-free programs, which follow best practices, into leaking their secrets. In fact, the safety checks of said best practices actually increase the attack surface and may make applications more susceptible to Spectre Spectre is harder to exploit than Meltdown, but it is also harder to mitigate.

  • Google's Project Zero and the Future of Altruistic Internet Security
    Google’s Project Zero and the Future of altruistic Internet Security By Katie Kurtz Abstract Google announced its new, web security initiative known as Project Zero in July 2014. Project Zero aims to address security flaws in popular third­party software that may be utilized by the networking giant. The goal is to identify and alert these companies to any vulnerabilities that could put internet users at risk. Zero­day vulnerabilities, or when unnoticed bugs allow attackers the chance to target thousands of users, are one of the biggest threats to web users. These vulnerabilities have been exploited by predators, state­sponsored hackers, and government agencies alike. Project Zero is the first example of a single team attempting to secure the entire web for primarily altruistic reasons. This paper will examine the risks of the current every­man­for­himself system of cyber security and the steps already taken by Google and Project Zero to secure the web, as well as the future implications of altruistic and universal web security and threat analysis. Introduction A brief look at the security structure of the internet The security of the internet has no form of regulation. At this point, safety and security is up to individual vendors. This system has not left internet users very secure. Google recently made the first step toward a perceived change. The internet giant announced in July that it created a team with the single responsibility of discovering zero­day vulnerabilities in third party software. They claim that they hope to offer a more secure browsing experience for Google users, but that their motivation is primarily altruistic.
