The Top 20 Vulnerabilities to Patch before 2020

Published first in Dark Reading by Kelly Sheridan.

In an ideal world, organizations would patch every new vulnerability once it’s discovered. In real-life, this is impossible. Security analysts responsible for vulnerability management activities face multiple challenges that result in what the industry calls “The Patching Paradox” – common sense tells you to keep every system up to date in order to be protected, but this is not possible due to limited resources, existence of legacy systems and slow implementation of patches.

Verint’s Cyber Threat Intelligence (CTI) Group analyzed the top 20 vulnerabilities that are currently exploited by attack groups worldwide. The goal of this analysis is to provide security professionals with an incentive to improve their patching management activities.

Key Findings:

  • 34% of the attacks exploiting these vulnerabilities, originated in China
  • 45% of the vulnerabilities affect Microsoft products
  • Vulnerabilities from as early as 2012 (!) are still used to carry out successful attacks

According to the National Vulnerability Database (NVD), since 2016 we have seen an increase of ~130% in the number of disclosed vulnerabilities, or in other words there is an average of ~45 new vulnerabilities per day as can be seen in the graph below. Additional statistics reveal that almost 60% of all vulnerabilities are classified as ‘Critical’ or ‘High’.

Recent threat intelligence gathered by Verint and Thales Group about 66 attack groups operating globally, revealed that advanced threat actors leverage old vulnerabilities that are left unpatched. To make things even more complicated, according to a recent study by Ponemon Institute for ServiceNow60% of breaches were linked to a vulnerability where a patch was available, but not applied.

So, How Can We Clean Up The Mess?

Operational Threat Intelligence – Each CVE is given a severity score. However, these scores do not necessarily represent the actual risk for the organization. For example, CVE-2018-20250 (WinRAR vulnerability) has a CVSS (Common Vulnerability Scoring System) base score of 7.8 (‘High’) in NVD and 6.8 (‘Medium’) in ‘CVE Details’. This vulnerability has been exploited by at least five different APT groups, from different locations, against targets in the U.S., South East Asia, Europe, and The Middle East and against a wide range of industries, including Government Agencies, Financial Services, Defense, Energy, Media and more. This information clearly indicates the criticality of the vulnerability and the urgency for immediate patching.

Other contextual data that should influence your patching prioritization process is what vulnerabilities are currently discussed in the Dark Web by threat actors, or which exploits are currently developed? Threat intelligence is key when we try to determine what vulnerabilities are critical to our organization. Maintaining a knowledge base of exploited vulnerabilities according to the attack groups leveraging them, provides a solid starting point for vulnerability prioritization. In addition, having information about the attack groups – for example their capabilities, TTPs and the industries and countries they target – helps to better evaluate the risk and prioritize patching activities.

The Top 20 Vulnerabilities to Patch Now

Verint’s CTI Group constantly monitors different intelligence data sources and create daily CTI feeds, which include the latest daily cyber activities. The analysis below is based on over 5,300 feeds and other intelligence items the group has analyzed in the past 2.5 years, covering over 800 CVEs.

The 20 vulnerabilities were extracted based on the number of times they have been exploited by sophisticated cyber-attack groups operating in the world today (from high to low):

Cyber Threats to the Aviation Industry

The aviation industry faces major risks on all of its fronts: from the air traffic control systems, to the aircraft themselves, to the airline companies and airports and border crossings. The identified threats stem from the current nature of aviation industry systems, which are interconnected and interdependent.

(Please note –  this blog post is an excerpt from our report: “Cyber Threats to the Aviation Industry”. If you are interested in receiving the full report please write to: info@sensecy.com)

On August 13, 2013, the AIAA officially released a Decision Paper entitled “A Framework for Aviation Cyber security”, outlining existing and evolving cyber threats to the commercial aviation enterprise and noting the lack of international agreement on cyber security in aviation. There is no common overall coordination of efforts seeking a global solution.

According to the report, the global aviation system is a potential target for a large-scale cyber attack with attackers focusing on malicious intent, information theft, profit, “hacktivism”, nation states, etc.

Aviation

The risks are not only theoretical. As portrayed below, some of the aforementioned security concerns have already been realized by hackers in real-life.

  • A presentation at the ‘Hack in The Box’ security summit in Amsterdam in April 2013 has demonstrated that it is possible to take control of an aircraft’s flight systems and communications using an Android smartphone.
  • Sykipot is a tool that serves as a backdoor that an attacker can use to execute commands on the affected system. It is being used to gather intelligence about the civil aviation sector in the U.S. Like most targeted attacks, Sykipot infects using spear-phishing techniques by sending emails with malicious attachments. Lately, as identified by Trend Micro, Sykipot has been observed gathering intelligence on the U.S. civil aviation sector. The intentions of this campaign are unclear as yet. Sykipot has a history of targeting U.S. Defense Initial Base (DIB) and key industries over the past six years.
  • Conficker, a worm that has infected millions of computers worldwide, infected the French Navy network on 2009, forcing it to cut connectivity to stop it from spreading, and to ground its Rafale fighter jets. It was probably introduced through an infected USB drive.
  • In 2008, Spanair flight 5022 crashed just after take-off, killing 154 people. According to the Spanish government’s Civil Aviation Accident and Incident Investigation Commission (CIAIAC), the disaster occurred because the central computer system used for monitoring technical problems in the aircraft was infected with a Trojan horse.
  • In 2008, the FAA reported that the computer network in the Boeing 787 Dreamliner’s passenger compartment was connected to the aircraft’s control, navigation and communication systems – a cause for grave security concern. This connection renders the plane control system vulnerable to cyber attack. Boeing advised that they would address the issue
Aviation sector under threat of cyber attacks

We believe that the aviation industry is facing major threats from cyberspace and these threats encompass large areas of the industry and may become a greater burden for it, compromising the safety of the passengers, and causing financial and commercial damage to the associated companies.
