REPORT: Over 22M Records Exposed In Data Breaches In 2020

An analysis of breach data by Tenable’s Security Response Team (SRT) has shown that from January to October 2020, there were 730 publicly disclosed events resulting in more 22 billion records exposed worldwide.

The Tenable report also highlighted that 35% of the breaches that were analysed were linked to ransomware attacks, resulting in tremendous financial cost, while 14% of breaches were the result of email compromises.

One of the overarching themes of the threat landscape in 2020 was that threat actors relied on unpatched vulnerabilities in their attacks as well as chaining together multiple vulnerabilities as part of their attacks.

This analysis has been published in Tenable’s 2020 Threat Landscape Retrospective (TLR) report which provides an overview of the key vulnerabilities disclosed or exploited in the 12 months ending December 31, 2020.

As organisations around the world prepare to face the new cybersecurity challenges looming in 2021, it’s crucial to pause and take a look back at the most critical vulnerabilities and risks from the past year.

Understanding which enterprise systems are affected by the year’s vulnerabilities can help organisations understand which flaws represent the greatest risk.

From 2015 to 2020, the number of reported common vulnerabilities and exposures (CVEs) increased at an average annual percentage growth rate of 36.6%.

In 2020, 18,358 CVEs were reported, representing a 6% increase over the 17,305 reported in 2019, and a 183% increase over the 6,487 disclosed in 2015. Prioritising which vulnerabilities warrants attention is more challenging than ever.

According to the report, pre-existing vulnerabilities in virtual private network (VPN) solutions — many of which were initially disclosed in 2019 or earlier — continue to remain a favourite target for cybercriminals and nation-state groups.

It also pointed out that web browsers like Google Chrome, Mozilla Firefox, Internet Explorer and Microsoft Edge are the primary target for zero-day vulnerabilities, accounting for over 35% of all zero-day vulnerabilities exploited in the wild.

Fixing unpatched vulnerabilities, implementing strong security controls for remote desktop protocol, ensuring endpoint security is up-to-date and regularly performing security awareness training are steps organisations can take to thwart some of these attacks.

“As defenders, it is difficult enough to prioritise remediation given the hundreds of vulnerabilities released on Microsoft’s Patch Tuesday every month and Oracle’s Critical Patch Update each quarter.

“Add in the impact from COVID-19 for defenders trying to protect their new remote workforce and you have a recipe for chaos,” said Satnam Narang, Staff Research Engineer at Tenable.

“Security teams know to pick their battles, but when there is a flurry of vulnerabilities with a CVSSv3 score of 10.0 released within weeks of each other, the battles are being chosen for you and they’re happening simultaneously.

“In order to manage vulnerability overload, you’ll need to take inventory of your entire network, identify your most critical assets and ensure they receive patches in an appropriate time frame.

“Additional indicators, such as CVSSv3 scores and the availability of PoC exploit scripts, can provide further insight into  whether or not  a vulnerability is more likely to be exploited in the wild, helping your team focus first on the most severe threats facing your network.”

Maher Jadallah, Regional Director – Middle East, Tenable, said, “If we learnt anything from 2020, it is that we are all reliant on the infrastructure and supply chains underpinning modern society — be it agriculture, pharmaceutical development, and food and beverage manufacturing — especially in times of crisis.

“Unfortunately, threat actors are also looking for ways to capitalise on any lowering of defences. The challenge might appear insurmountable — particularly given the ever-expanding attack surface of IT, operational technology (OT) and internet of things (IoT) devices.

“Given the reliance of threat actors on unpatched vulnerabilities, it is increasingly obvious that vulnerability management has a central role to play in modern cybersecurity strategies.”
