Cybercriminals Disabled or Wiped Out Logs in 82% of Ransomware Attacks with Missing Telemetry in Cases Analyzed – Sophos Finds

“Fast” Ransomware Attacks Hinder Fast Defender Response, says Sophos in thie report by SANDRA ANI

Sophos’ Annual State of Ransomware

38% of “Fast” Ransomware Attacks in Report Occurred within 5 Days of Initial Access

Sophos, a global leader in innovating and delivering cybersecurity as a service, has released its Active Adversary Report for Security Practitioners, which found that telemetry logs were missing in nearly 42% of the attack cases studied. In 82% of these cases, cybercriminals disabled or wiped out the telemetry to hide their tracks.

The report covers Incident Response (IR) cases that Sophos analyzed from January 2022 through the first half of 2023.

Gaps in telemetry decrease much-needed visibility into organizations’ networks and systems, especially since attacker dwell time (the time from initial access to detection) continues to decline, shortening the time defenders have to effectively respond to an incident.

“Time is critical when responding to an active threat; the time between spotting the initial access event and full threat mitigation should be as short as possible. The farther along in the attack chain an attacker makes it, the bigger the headache for responders. Missing telemetry only adds time to remediations that most organizations can’t afford. This is why complete and accurate logging is essential, but we’re seeing that, all too frequently, organizations don’t have the data they need,” said John Shier, field CTO, Sophos.

In the report, Sophos classifies ransomware attacks with a dwell time of less than or equal to five days as “fast attacks,” which accounted for 38% of the cases studied. “Slow” ransomware attacks are those with a dwell time greater than five days, which accounted for 62% of the cases.

When examining these “fast” and “slow” ransomware attacks at a granular level, there was not much variation in the tools, techniques, and living-off-the-land binaries (LOLBins) that attackers deployed, suggesting defenders don’t need to reinvent their defensive strategies as dwell time shrinks. However, defenders do need to be aware that fast attacks and the lack of telemetry can hinder fast response times, leading to more destruction.

“Cybercriminals only innovate when they must, and only to the extent that it gets them to their target. Attackers aren’t going to change what’s working, even if they’re moving faster from access to detection. This is good news for organizations because they don’t have to radically change their defensive strategy as attackers speed up their timelines. The same defenses that detect fast attacks will apply to all attacks, regardless of speed. This includes complete telemetry, robust protections across everything, and ubiquitous monitoring,” said Shier. “The key is increasing friction whenever possible—if you make the attackers’ job harder, then you can add valuable time to respond, stretching out each stage of an attack.

“For example, in the case of a ransomware attack, if you have more friction, then you can delay the time until exfiltration; exfiltration often occurs just before detection and is often the costliest part of the attack. We saw this happen in two incidents of Cuba ransomware. One company (Company A) had continuous monitoring in place with MDR, so we were able to spot the malicious activity and halt the attack within hours to prevent any data from being stolen. Another company (Company B) didn’t have this friction; they didn’t spot the attack until a few weeks after initial access and after Cuba had already successfully exfiltrated 75 gigabytes of sensitive data. They then called in our IR team, and a month later, they were still trying to get back to business as usual.”

The Sophos Active Adversary Report for Security Practitioners is based on 232 Sophos Incident response (IR) cases across 25 sectors from Jan. 1, 2022, to June 30, 2023. Targeted organizations were located in 34 different countries across six continents. Eighty-three percent of cases came from organizations with fewer than 1,000 employees.

The Sophos Active Adversary Report for Security Practitioners provides actionable intelligence on how security practitioners should best shape their defensive strategy.

Sophos Partners with Tenable to Launch New Sophos Managed Risk Service

Published

Sophos Partners with Tenable

. New Fully Managed Solution Provides Visibility, Risk Monitoring, Prioritization, Investigation, and Proactive Notification to Prevent Cyberattacks  

April 4, 2024 – Sophos, a global leader of innovative security solutions that defeat cyberattacks, today announced a strategic partnership with Tenable, the Exposure Management company, to provide Sophos Managed Risk, a worldwide vulnerability and attack surface management service.

The new service features a dedicated Sophos team that leverages Tenable’s exposure management technology and collaborates with the security operations experts from Sophos Managed Detection and Response (MDR) to provide attack surface visibility, continuous risk monitoring, vulnerability prioritization, investigation, and proactive notification designed to prevent cyberattacks.

The modern attack surface has expanded beyond traditional on-premises IT boundaries, with organizations operating frequently unknown numbers of external and internet-facing assets that are unpatched or under protected, leaving them vulnerable to cyberattackers.

This is evident in the newest Sophos Active Adversary Report, also released, which identifies three tasks that organizations must prioritize to minimize the risk of brazen intrusions that lead to ransomware or other types of attacks.

These include closing exposed Remote Desktop Protocol (RDP) access, enabling multi-factor authorization and patching vulnerable servers, all of which were top entry points in breaches handled by Sophos Incident Response in 2023.

The Sophos Managed Risk service can assess an organization’s external attack surface, prioritize the riskiest exposures, such as open RDP, and provide tailored remediation guidance to help eliminate blind spots and stay ahead of potentially devastating attacks.

“Sophos and Tenable are two industry security leaders coming together to address urgent, pervasive security challenges that organizations continuously struggle to control. We can now help organizations identify and prioritize the remediation of vulnerabilities in external assets, devices and software that are often overlooked. It is critical that organizations manage these exposure risks, because unattended, they only lead to more costly and time-consuming issues and are often the root causes of significant breaches,” said Rob Harrison, senior vice president for endpoint and security operations product management at Sophos. “We know from Sophos’ worldwide survey data that 32% of ransomware attacks start with an unpatched vulnerability and that these attacks are the most expensive to remediate. The ideal security layers to prevent these issues include an active approach to improving security postures by minimizing the chances of a breach with Sophos Managed Risk, Sophos Endpoint, and 24×7 Sophos MDR coverage.”

“While the latest zero day may dominate the headlines, the biggest threat to organizations, by a large margin, is still known vulnerabilities – or vulnerabilities for which patches are readily available,” said Greg Goetz, vice president of global strategic partners and MSSP, Tenable. “A winning approach includes risk-based prioritization with context-driven analytics to proactively address exposures before they become a problem. Sophos Managed Risk, powered by the Tenable One Exposure Management Platform, delivers outsourced preventive risk management, enabling organizations to anticipate attacks and reduce cyber risk.”

Specific key benefits of Sophos Managed Risk include:

  • External Attack Surface Management (EASM): Advanced identification and classification of internet-facing assets, such as web and email servers, web applications, and public-facing API endpoints
  • Continuous monitoring and proactive notification of high-risk exposures: Proactive notification when a new critical vulnerability is identified in an organization’s internet-facing assets
  • Vulnerability prioritization and identification of new risks: Swift detection of high-risk and zero-day vulnerabilities, followed by real-time notification to ensure critical internet-facing assets are promptly identified, investigated and responded to by order of importance

“One of the biggest challenges organizations face when improving their security posture is prioritizing what to handle first. This type of guidance helps solve that issue and reduces the workload for security teams tasked with tackling vulnerability and exposure management,” said Craig Robinson, research vice president of Security Services, IDC. “Solutions such as Sophos Managed Risk can be a differentiator by enabling overwhelmed teams to take a more holistic approach to continuous monitoring and threat management.”  

Sophos Managed Risk is available as an extended service with Sophos MDR, which already protects more than 21,000 organizations globally. The Sophos Managed Risk team is Tenable-certified and works closely with Sophos MDR to share essential information about zero-days, known vulnerabilities and exposure risks to assess and investigate possibly exploited environments.

“Sophos Managed Risk simplifies the difficult and resource consuming task of identifying vulnerabilities, really understanding the extent of risk exposure, and prioritizing necessary remediations,” said Kieron Stone, cybersecurity business development manager at Phoenix Software Ltd. “As a trusted managed service provider (MSP), this is a service we’re proud to stand behind, and nearly all our customers using it have already discovered significant vulnerabilities that they were previously unaware of. For organizations that don’t already have a well-defined vulnerability patching cadence, this is a must-have service for the identification of vulnerabilities and building that schedule; and for organizations that are already managing vulnerabilities, it’s a second set of eyes for added peace of mind that they’re not missing anything.”

Organizations benefit through regular interaction, including scheduled meetings with Sophos experts to review recent discoveries, insights into the current threat landscape, and recommendations for remediation and prioritizing actions. Additionally, organizations can initiate inquiries via the Sophos Central platform, allowing users to directly engage with the Sophos Managed Risk team for tailored support, reports and to review their latest prioritized alerts.

“You can’t fix what you can’t see. Sophos Managed Risk is shining a light on areas of exposure that require remediation in order to keep customers protected. Combining Sophos’ elite MDR experts with Tenable’s industry-leading exposure management technology gives us a full picture view of vulnerabilities with the guidance we need to minimize risk,” said Brooks Roy, president at Communications Consulting, Inc. “The real value add for us as a channel partner is having the ability to easily manage Sophos Managed Risk’s prioritized alerts across our customer base on the Sophos Central dashboard.”

Sophos Managed Risk is available with a term license through Sophos’ global network of channel partners and Managed Service Providers (MSPs). A Sophos MSP Flex version will be available in 2024.

Kingsely Adonu, founder and CEO, S Mobile Group

•⁠ ⁠500 successful candidates to get starter-packs

•⁠ ⁠Rolls our Free Data, Airtime to Civil Servants, Students, others

S Mobile Tech Hub, an offspring of S Mobile Group has open applications to technology entrepreneurs in the Southeast Nigeria.

S Mobile Tech Hub was recently conceived by Mr. Kingsley Adonu, a visionary entrepreneur and CEO/Founder S Mobile Group, who aims to manifest the Group’s deliberate programmes towards building a dynamic and vibrant startup ecosystem in eastern region of the country.

APPLY by visiting www.smobilegroup.com to register.

Speaking against this backdrop, Mr. Adonu, said that even against tremendous challenges faced by the youth in the Southeast, they must be actively engaged in digital skills development in order to eschew social vices and make positive contributions towards maintaining peace and progress in the region.

“Unfortunately, a lot of our young people are facing numerous barriers to participating in formal and informal sectors today. In December 2015, the United Nations Security Council adopted UNSCR 2250 on Youth, Peace and Security. The resolution was the first to recognise the important role young people can play in preventing conflicts, and sustaining peace.

“It is on this premise and more that S Mobile is thinking out of the box by extending digital skills programmes to empower the youth to be more economically relevant. This will also go a long way in supporting the efforts of the Governors in the Southeast who are not resting on their oars until we have crime-free society with less poverty index.

“S Mobile Tech Hub has been positioned as a platform for entrepreneurs to leverage trends to accelerate their skills and innovation especially in the areas of artificial intelligence, robotics, big data, etc., which have become embedded in our daily lives.

“We are rolling out free data and airtime to civil servants, students, farmers and other entrepreneurs, for connecting with MTN Nigeria services.

Also during the cohort 1 of S Mobile Tech Hub programme 500 successful technology entrepreneurs across the Southeast region will be sponsored with the starter-tools to live their dreams.

“Together, let’s turn technology into your personal pathway to empowerment, growth, and societal well-being. Don’t just dream about a brighter tomorrow; let’s build it together today!”, the company said on Wednesday.
