Why cyberspace remains largely unaffected amidst ongoing geopolitical turmoil

The lack of any large cyber incidents doesn’t mean things are still deep under. Instead, this could well be the lull before a cyberstorm.     Earlier this week, Iran-linked APT group Charming Kitten (aka Ballistic Bobcat APT, APT35, and Phosphorus) initiated a fresh cyber espionage campaign targeting 14 countries across the globe. The objective of these attacks was to exfiltrate data and to open backdoors for long-term espionage.   Telemetric analysis conducted by Sectrio’s Threat Research Team revealed a higher level of APT 35 activity than ever before with governments, healthcare institutions, oil and gas, and manufacturing entities being targeted. The group is targeting these entities at two levels one is by attacking exchange servers and two by sending large-scale phishing campaigns using ‘critical media updates’ as the subject line.   In addition to this, certain groups are also scaling up their reconnaissance attacks taking advantage of the distraction that has been created by the large-scale DDoS and defacing attacks carried out by other groups. This is a pattern that we have often seen in the past where website defacing attacks are often used to cover targeted attacks.      As conflicts in the Middle East and Eastern Europe draw on, information warfare, or more specifically information held for ransom could become a game-changer for the parties involved. This is why we have not seen any major cyber incidents occurring since the latest outbreak of hostilities. However, knowing cyberspace, things could escalate quickly if the information already pilfered is put to use by the threat actor concerned or by their backers.       Cyberspace realities: Change in tactics Unlike past geopolitical conflicts where cyberspace was impacted almost immediately, the biggest impact this time around has been limited to DDoS attacks on websites and the compromise of social accounts. That’s how most of the attacks panned out. However, reconnaissance and data exfiltration attacks on businesses have also grown but not as significantly as the DDoS attacks.   To-do list for CISOs and Security leaders Thus, things might escalate quickly reducing your time to respond. Here is an immediate to-do list for you as a CISO or a security leader:   How sectrio can help Sectrio is a one stop solution to secure all the above needs and requirements.

This legacy technology often lacks the built-in security measures present in modern systems, making them vulnerable to attacks. Lack of Regular Updates: Unlike consumer technology, OT systems may not receive regular updates or patches. This absence of updates leaves security gaps that attackers can exploit. Proprietary Protocols: OT often relies on proprietary communication protocols unique to specific industries. While these protocols enhance efficiency, they can also obscure vulnerabilities from common security assessments. Impact on Critical Infrastructure The consequences of exploiting OT vulnerabilities extend far beyond the digital realm. Consider a scenario where an attacker gains unauthorized access to a power plant’s control system. They might tamper with the settings by exploiting weaknesses, resulting in power outages or equipment damage. This poses a possible risk to both public safety and the economy in addition to being an inconvenience. Furthermore, the ripple effect of an OT breach can extend to other sectors that depend on the affected infrastructure. A single breach could trigger a chain of disruptions, potentially causing widespread chaos. Bridging the Gap: IT vs. OT One of the challenges in understanding OT vulnerabilities lies in the different approaches to cybersecurity between Information Technology (IT) and OT. While IT focuses on data security and confidentiality, OT prioritizes the uninterrupted functioning of physical processes. This discrepancy can lead to blind spots in security measures, exposing OT systems. To complicate matters, IT and OT often share networks due to cost-saving measures. This convergence introduces vulnerabilities in both systems, as attacks could migrate from one to the other. Recommended Reading: Getting started with OT security Understanding the vulnerabilities in Operational Technology is the first step toward securing critical systems. By recognizing the challenges posed by legacy technology, the lack of updates, and the unique landscape of OT, we gain insight into the vulnerabilities attackers seek to exploit.  The Significance of Vulnerability Assessment and Penetration Testing (VAPT) in Operational Technology (OT) The marriage of digital technology with physical processes creates a unique challenge that traditional security measures struggle to address. This is where Vulnerability Assessment and Penetration Testing (VAPT) is a guardian of reliability, safety, and operational continuity. Protecting the Heartbeat of Industries Operational Technology serves as the heartbeat of critical infrastructure. Whether it’s the controlled flow of electricity, the precision of manufacturing, or the orchestration of transportation, OT’s influence is undeniable. Yet, as industries rely increasingly on interconnected systems, the potential for cyber threats to infiltrate and disrupt these processes grows exponentially. While essential, traditional security methods, like firewalls and antivirus software, fall short in the face of rapidly evolving cyber tactics. Here, VAPT emerges as the linchpin of defense. By proactively identifying vulnerabilities and simulating attacks, VAPT exposes weak points that adversaries could exploit, enabling timely remediation. The Limitations of Traditional Security The limitations of traditional security measures in OT environments become apparent when we consider the unique characteristics of these systems. Unlike Information Technology (IT), where data protection is paramount, OT focuses on maintaining the continuity and reliability of physical operations. The primary concern isn’t just data breaches but potential operational disruptions that could have cascading effects. VAPT bridges the gap between traditional security and the specific needs of OT. It assesses the cybersecurity landscape through the lens of operational impact, highlighting vulnerabilities that might otherwise go unnoticed by generic security measures. The VAPT Approach: Proactive Defense Vulnerability Assessment and Penetration Testing don’t wait for attackers to strike. Instead, they adopt a proactive stance. Here’s how each component contributes to the robust defense of OT systems: Vulnerability Assessment (VA): This phase systematically identifies vulnerabilities across the OT environment. Automated scans and manual analysis uncover potential weak points, whether they stem from outdated software, configuration errors, or undiscovered backdoors. Penetration Testing (PT): With insights from the VA, the PT phase simulates attacks in controlled environments. Ethical hackers attempt to exploit identified vulnerabilities, mimicking the tactics of real attackers. The goal is to understand how these vulnerabilities could be leveraged and assess their impact. A Unified Defense Strategy VAPT’s significance lies in its ability to unite IT and OT security efforts. The collaboration between these two traditionally separate domains is vital to safeguarding the convergence of digital and physical processes. VAPT testing ensures that security measures don’t inadvertently disrupt operational functionality, striking a delicate balance that secures without hindering. In a landscape where the stakes are as tangible as digital, VAPT serves as a vigilant watchman, detecting vulnerabilities that could

OT Attack Path Analysis: A Comprehensive Guide

The convergence of Information technology (IT) and Operational technology (OT) networks, resulting in the exposure of OT networks to threats, paved the way for OT cybersecurity. OT is the use of hardware and software in critical infrastructure industries like, power, energy, water treatment, manufacturing, etc. Compromise to the security in these industries can result in cascading effects. To secure the safety of industries from cyberattacks, organizations come up with many solutions, with attack path analysis being one of them.  What is attack path analysis? Attack path analysis is the graphical representation of pathways to crucial data in your organziation, which cybercriminals adapt to gain access. Through attack path analysis, organizations are structured to think the way a bad actor thinks. It is the simulation of ways used by attackers to implement mitigation strategies.  With the help of attack path analysis, organizations can prioritize threats and take remediation measures accordingly. The need for attack path analysis A typical organization, on an average, has 11,000 exploitable security exposures in just one month. The need for attack path analysis cannot be emphasized more! The following are some more points to highlight the need: Increased spectrum of threats There has been an increase in the kinds of threats, and new ones also emerge every day. Every threat is based on some financial, political and other motives, and cybercriminals work toward the disruption of the OT systems to attain them.  OT systems manage critical infrastructure, and as such, they are easy targets for attackers. This necessitates that you should keep the OT environment alert with an analysis of the possible path taken by hackers and other cybercriminals. The complexity of the OT environment OT environment is complex and depends on different devices, systems, and networks. With high interdependency, an attack on one could lead to devastating effects on the OT environment.  With the help of attack path analysis, you can understand how attacks could surface and ways to tackle them. Some attacks may appear unrelated, but the analysis could lead to insightful findings that could save the organization thousands of dollars. Compromise due to insider attacks OT environments are greatly impacted by insider attacks, as people having access have immense technical knowledge and operational expertise to misuse them. This can be kept under check through attack path analysis. The exploration of ways insiders could use their expertise to scan through systems and exploit them helps to locate threats much before they could happen. This saves the organization from potential attacks that could otherwise be severe. Regulatory requirements Attack path analysis is also needed as a part of compliance with regulatory requirements. Industries with OT systems have certain mandatory requirements. This is required for data protection in view of the increased possibility of attacks on cybersecurity systems.  Keep business operations on track There could be total mayhem when a successful cyberattack disrupts business continuity. This can potentially lead to a loss of several millions of dollars and negatively impact the business’s reputation. With attack path analysis, companies are always on the lookout for attacks, and this helps reduce downtime. The company can also bounce back easily when they are proactive and prepared with an assessment of security. Assess the priority of exposure In many organizations, security concerns that require attention are often overlooked. This is because there are too many assets on their network and identifying risks becomes difficult.  This can be avoided with the help of attack path analysis.  It helps analyze the priority of exposure of assets and thereby to be ready with protection mechanisms before an attack can surface.  Visualize the way a hacker could think Seeing the attack paths like a hacker could provide complete visibility of the risks involved. It helps visualize the potential attack chains so that it is easy to understand the assets that could be targeted. Factors like host reachability, misconfigurations, vulnerabilities, etc., are all risk factors that can be correlated to help fix security issues. Steps to perform OT attack path analysis A series of steps, as listed below, need to be followed for effective attack path analysis: 1. Definition of scope The scope and goals of your analysis must be laid down in clear terms. What are the OT systems, assets, etc., you want to analyze? What is the purpose of your analysis? These are some questions you should answer before you start. List out the possible vulnerabilities and attack vectors that you wish to uncover through this analysis. This definition gives a proper direction to your activity. 2. Identify the critical systems There are several critical assets and systems in the OT environment that are exposed to threats. These should be identified so that the priority of threats can be ascertained. Threats need to be addressed in the order of their criticality so that the most crucial ones can be dealt with first. This can help an organization greatly as serious threats are easily identified and thwarted.  3. Mapping of the flow of data Data moves through multiple points, of which some may be prone to weaknesses. Mapping data flows can help locate the weak points so that they can be addressed. Understanding the flow of data enables the identification of paths attackers may emerge from.  4. Identify threats and vulnerabilities You should conduct a vulnerability assessment and threat analysis that is specific to the OT environment. This helps identify the various weaknesses and probable impacts they could cause. Timely assessment is an important step as it prevents attacks from happening and thereby maintains business continuity. 5. Assess the attack vectors An attack vector is the pathway attackers enter the OT environment. They could be credential theft, malware, social engineering attacks, insufficient protection, etc.  Analysis of the attack vectors helps identify ways to avoid them. For example, the data and network access of every employee have to be assessed to prevent insider attacks.  6. Identify the attack scenario The mode of operation that the attacker might opt has to be defined. All paths that

Fundamentals of attack path analysis in an OT environment

At its core, an attack path analysis presents a powerful visual and impactful representation covering a potential path that cyber threat actors or malicious payloads may tread to breach asset or network targets. The benefits justify resource and attention investments in an APA exercise. In addition to helping disrupt the changes of a successful cyberattack, it can also improve the maturity of your OT security team.    The depiction of a compromise path, so to speak, presents a visual dimension to a possible attack and enables security teams, SOC analysts, CISOs, and security decision-makers to derive and deploy countermeasures. Attack Path Analysis also helps prioritize vulnerabilities for action based on a deeper understanding of the impact a possible cyberattack could have.   How to approach Attack Path Analysis in an OT environment  An OT environment can present several challenges to the smooth conduct of an Attack Path Analysis effort. Knowledge of the environment, operational dynamics, asset topology and vulnerabilities are essential. As we have seen many times before, many OT operators do not have such information or lack information at the level required to conduct an APA in a structured manner. The relevance of the outcome of the APA for your organization depends on many factors.    To conduct an APA in an OT environment and to get results that matter, these pre-requisites have to be in place:  Once the above data is in place, a model can be derived to map the possible attacks and the targets along with the path an attack could potentially take. Contextual information that enables a direct correlation between targets, breach points, conduits, and the overall path can then be ascertained.   Reccommended reading: Complete Guide to Cyber Threat Intelligence Feeds APA should not be seen as a drawing board/whiteboard exercise to be conducted on paper. Instead, APA should be conducted as an objective exercise to identify and break existing attack paths and reduce the changes of a new one appearing in the future.    Charting the course of an attack   It is not essential for an attack to move horizontally in a network in a linear manner. Thus, when drawing the attack path, the model must be able to offer multiple paths with the probability of the attacker choosing a specific path to a target and link that with the probable success ratio. This will help security teams focus their attention on breaking the attack path through specific interventions starting with the most probable paths.   When deciding on prioritizing interventions the following aspects can be used to derive a path score:  Benefits of an Attack Path Analysis   Conducting an APA can lead to many benefits for your organization.

Deconstructing the CL0P RaaS group and understanding the MOVEit breach in 2023

The large-scale incorporation of connected OT/SCADA systems is a growing trend but are you aware of the increasing presence of sophisticated threat actors and rapidly budding ransomware variants? The question you should ask yourself and your peers is “Are my OT/SCADA systems secure against next-generation cyber threats? In this blog, we will be discussing particular instances where CL0P ransomware has been identified in OT/SCADA systems. OT/SCADA systems control physical devices and processes, such as water treatment plants, power grids, and manufacturing plants. These systems are often susceptible to attacks due to their setup, pre-existing vulnerabilities and often targeted as a result of lax security protecting these systems. While the scale of attacks targeting such systems can be analyzed further in our global threat landscape report 2023, it is imperative to understand the motive of the actors behind such attacks. With Sectrio’s ongoing research initiatives, CL0P is one such ransomware that has popped up on our radar multiple times. Its usual methods include infiltration via phishing emails, malicious attachments, and exploit kits. The RaaS group operates methodically and begins its process through meticulous research of its victim on its operations, and understanding how they can be exploited. Recommended Reading: How to get started with OT security CL0P follows this process with social engineering, and spear phishing techniques where they are looking to penetrate the victim’s network and deploy the ransomware exploits. After the successful deployment of the ransomware, CL0P publishes a portal on the dark web for the victim to first verify 3 files to validate the compromise and requests a ransomware payout. The whole ordeal lasts between 3 – 7 days. The victim suffers from operational halts, reputational damages, loss of IP, and financial losses. This report is a comprehensive analysis of CL0P ransomware including attack techniques, verticals targeted, countries targeted, and attack scenarios on OT-specific verticals. Stick around and learn more! Who is CL0P? CL0P is a notorious ransomware as a service (RaaS) operation that a Russian-speaking group operates. CL0P was first seen in February 2019 as a new variant in the Cryptomix family. It was delivered as a payload of a phishing campaign associated with the financially motivated actor TA505. CL0P was able to inject malicious code into the company’s database servers by exploiting a zero-day vulnerability using SQL injection. This allowed the attackers to access and download the data stored in the databases. This ransomware also used a verified and digitally signed binary, making it look like a legitimate executable file that could evade security detection CL0P Ransomware The CL0P ransomware is one of the biggest malware threats in cyberspace today. The attackers once demanded an amount of more than 20+ Million Dollars to restore services from their victim. Targeting SCADA systems with CL0P ransomware presents a grave risk to vital infrastructure, carrying the potential for operational breakdowns, substantial financial damages, and even endangering human safety. Exploiting vulnerabilities within SCADA systems, malicious actors can illicitly infiltrate and encrypt crucial control files, resulting in the cessation of industrial operations or even the discharge of dangerous materials. In June 2023, the CL0P ransomware group exploited a zero-day vulnerability in the MOVEit Transfer tool. This vulnerability was announced on May 31, 2023, by the Progress Software Corporation. Earlier this year, CL0P had used a similar vulnerability to attack the GoAnywhere file transfer product of Fortra, stealing data from more than 130 companies, governments, and organizations. The CL0P attack on MOVEit Transfer is believed to have affected hundreds of organizations worldwide. CL0P Darkweb page On the Dark web page, they upload notes, news, and data published information and steps to contact them. Steps for Companies Attacked by CL0P Ransomware Gang CL0P Gangs uploads published data and victim organization names on their dark web page. Companies name attacked by CL0P Ransomware Gang CL0P Email IDs for communication The ransomware has been known to use Email ID: UNLOCK@RSV-BOX.COM, This was however changed to Email ID: UNLOCK@SUP-BOX.COM. We believe that this change was triggered as a result of technical challenges. Timelines of CL0P Ransomware and MOVEit The CL0P ransomware gang was relatively inactive from November 2022 to February 2023 than in March and April of 2023 as accurately predicted in Sectrio’s Global Threat Landscape Analysis and Assessment Report and stated by the NCC report stated that CL0P went from one of the least active threat groups in March to the fourth most active in April. This significant increase in CL0P ransomware activity is a cause for concern, as it suggests that the gang is becoming more active and successful in its attacks. Businesses and organizations should be aware of the CL0P threat and take steps to protect themselves from ransomware attacks. Affected Countries by CL0P Ransomware Tools, Malwares, and Vulnerabilities Used by CL0P Ransomware Malware FlawedAmmyy SDBOT Get2 Loader Malwares used by CL0P Tools Cobalt Strike TinyMet Tools used by CL0P List of vulnerabilities exploited by CL0P ransomware The exploits built are prepared using the vulnerabilities below: CVE ID Vulnerability Type CVSS Score and Severity CVE-2023-34362 SQL injection vulnerability 9.8 Critical CVE-2023-35036 SQL injection vulnerability 9.1 Critical CVE-2023-0669 Pre-authentication command injection 7.2 High CVE-2021-27101 SQL injection vulnerability 9.8 Critical CVE-2021-27102 OS command execution. 7.8 High CVE-2021-27103 SSRF via a crafted POST request 9.8 Critical CVE-2021-27104 OS command execution 9.8 Critical CVE-2021-35211 Remote code execution (RCE) vulnerability 10.0 Critical vulnerabilities exploited by CL0P ransomware Analysis of CL0P Ransomware TA505 is a threat actor that uses phishing emails to deliver malware to its victims. The malware typically arrives as a macro-enabled document that, when opened, drops a loader named Get2. Get2 can then download other tools used by TA505, such as SDBot, FlawedAmmyy, or FlawedGrace. Once TA505 has gained a foothold on the victim’s system, it will perform reconnaissance, lateral movement, and exfiltration. This will allow them to gather information about the victim’s network and systems and to move laterally to other systems within the network. The final step is to deploy ransomware, encrypting the victim’s files and demand a ransom payment. Sometimes, SDBot has been

Your organization’s readiness to deal with cyberattacks, not resistance to them, is what matters. So, Are You Ready to Elevate Your OT Security? Let’s Begin. Here’s why effective vulnerability management is non-negotiable in the world of OT: Preserving Operational Continuity Disruptions can lead to catastrophic consequences in OT environments. Vulnerabilities in industrial control systems (ICS) or SCADA systems can not only halt operations but also compromise safety. Implementing a robust vulnerability management strategy ensures that operational processes continue smoothly without compromising the integrity of the systems. Mitigating Cyber Risks Malicious actors constantly seek vulnerabilities to exploit. For OT, this could result in unauthorized access to critical systems or even the manipulation of processes, leading to financial losses and reputational damage. Effective vulnerability management is a proactive shield against cyber threats, reducing the organization’s risk exposure. Compliance and Regulations Many industries operating in the OT sector are subject to stringent regulations and compliance standards. Adhering to these requirements necessitates a comprehensive vulnerability management approach. Failure to do so not only invites legal consequences but also puts the organization at risk of cyber incidents. Let’s explore some notable standards that regulate OT security ISA/IEC 62443 (International Society of Automation/International Electrotechnical Commission) This comprehensive standard outlines the cybersecurity requirements for industrial automation and control systems. With its multi-part framework, IEC 62443 addresses various aspects of OT security, from network design to system lifecycle management. Its global recognition underscores its significance in safeguarding industrial processes against cyber threats. Download Checklist: The IEC 62443 Checklist NCAs OTCC-01: 2022 (National Cybersecurity Agency of Saudi Arabia) The Saudi Arabian regulatory body provides a set of guidelines, OTCC-01, focusing on securing industrial systems against cyber risks. These guidelines encompass risk management, security architecture, incident response, and more, providing organizations with a structured approach to OT security.
