How Cybersecurity Readiness Prevents SMBs from Fuelling Supply Chain Attacks

Published

Written by Ram Narayanan, Country Manager at Check Point Software Technologies, Middle East

Supply chain attacks aren’t new. If the past couple of years has taught businesses anything, it’s that the impact of supply chain cyber-attacks is now, universal, from the fallout of the SolarWinds software breach to the exposed Apache Log4j vulnerability and Kaseya last year. Unfortunately, when such supply chain attacks hit smaller businesses who are usually the suppliers to larger enterprises, their impact is especially prohibitive.

For SMBs already feeling the prolonged impact of the pandemic, the added pressure of dealing with sophisticated and frequent cyber attacks in real-time, is a heavy burden, as they try to protect their business against financial, legal, and reputational damage, as well as their own suppliers and larger clients’ security. It is now more important than ever for SMBs to implement strict security hygiene and effective cybersecurity processes to ensure their business is prepared for the event of cyber attacks happening.

SMBs as an indirect avenue of cyber attacks
The ‘new normal’ opened the door to several new vulnerabilities; cyber-attacks globally increased by 50% on average in 2021, compared to 2020. Our Check Point Threat Intelligence report revealed that an organisation in the United Arab Emirates is being attacked on average 906 times per week in the last six months. While security breaches are on the rise, the top threats impacting SMBs have remained the same. In Check Point’s Small and Medium Business Security Report from 2020/2021, we revealed phishing, malware, credential theft, and ransomware to be the top four threats impacting these businesses. So, what does this mean for them?

The reality is threat actors have taken advantage not only of the now-entrenched remote working model to target organisations, but also the usual limits preventing SMBs from bulking up on their cyber security defenses, mainly lack of budget and expertise. SMBs often do not have a dedicated IT or security department, meaning with no in-house security expertise and reduced focus on security patching, these companies are easier to socially engineer and infiltrate.

Adding to this, SMBs usually have employees doing multiple roles, and thus wider access to valuable areas of the business and information is given to them, and so if breached, they pose a  threat to multiple areas within the business. In addition, the business IT infrastructure is often shared for personal use communication as well eg. social media, personal emails allowing easier access to hackers, as the data is often not secured.

Threat actors often target SMBs as low-hanging fruit for their vital role in supply chains. This is especially so as such attacks wreak havoc on not only one organisation but entire businesses within the supply networks. By leveraging tactics such as phishing, cybercriminals gain access to an organisation to launch a malware attack, steal data and credentials or instigate ransomware.

Take, for example, the attack against Target USA where hackers used stolen credentials from an SMB vendor that serviced the HVAC systems in Target stores, to gain access to the retailer’s network and then laterally move to the systems that kept customer payment information. As a result, the global retailer was breached and 40 million credit and debit card details stolen.

The key factor to preventing cyberattacks is threat prevention. With minimal time and lack of cyber expertise or manpower, SMBs must adopt a prevention mindset to minimise potential cyber-attacks and threats.

Why cybersecurity readiness is paramount for SMBs
Beyond the immediate financial impact and reputational blow as a trustworthy, reliable partner, SMBs can also face legal or regulatory repercussions, operational disruption, flow-on costs for system remediation and cyberattack response, customer churn, and the loss of competitive advantage that can make or break a smaller business. In fact, a tarnished reputation as an avenue of attack can be even more detrimental to an SMB organisation, as the loss of trust with a larger organisation could mean a loss of potential business and revenue down the line with them or other new, potential customers.

With this in mind, budgetary constraints to keep computers and corporate networks protected should never be an excuse, as keeping sensitive data and information protected will bring many advantages and benefits to companies. This can range from overall cost savings, compliance with data protection laws, gaining the trust of customers and suppliers, to protecting your documents and information to the maximum by preventing any type of data breach.

How SMBs can prevent supply chain attacks
By applying stronger cyber defences, SMBs are in a position to provide larger organisations with assurance that larger companies they supply to will not be compromised via the SMB partner or third-party vendor. Whilst there are multiple means to prevent such supply chain attacks, the first step is to have good software capable of covering the entire company, protecting the company’s endpoints and devices, supported by regular backups so that, in the event of a cyberattack, they have the possibility of restoring all the data.

Any device that connects to the network can become a security breach, so it is important to secure all endpoints. It is especially critical for remote or hybrid workforces to avoid security breaches and data compromise. Also, all employees should be trained in cybersecurity so that they themselves become the first barrier to any attempted attack, such as phishing via email or SMS. Keep in mind that prevention is one of the best protection measures available.

A viable option for SMBs is to also consider engaging an experienced Managed Security Service Provider (MSSP), who will have the skilled resources, updated security software and experienced expertise to monitor for and analyse threats on behalf of the SMB player. This is especially useful for SMBs who have neither the time nor resources to adequately enforce threat detection and response.

Partnering with a cybersecurity expert equipped with best-in-class security and scalable solution such as Check Point Software can put SMBs in good stead to protect against the most sophisticated attacks and generate trust among larger potential players. Ultimately, SMBs seek a simple plug-and-play solution with best-in-class threat protection, given their lack of financial funding and skills. With an effective cybersecurity strategy, SMBs are better placed to demonstrate their credibility as secure partners to larger organisations, opening up more business opportunities.

CrowdStrike Announces New Features for the CrowdStrike Falcon Platform

Published

on

CrowdStrike has introduced the industry’s first AI-powered Indicators of Attack (IoAs), new innovations for fileless attack prevention at scale and enhanced visibility for stealthy cloud intrusions. Delivered on the CrowdStrike Falcon platform and powered by the CrowdStrike Security Cloud, these new detection and response capabilities stop emerging attack techniques and enable organizations to optimize the threat detection and response lifecycle with speed, scale and accuracy.

More than a decade ago, CrowdStrike invented IoAs, which brought a fundamentally new approach to stopping breaches based on real adversary behaviour, irrespective of the malware or exploit used in an attack. CrowdStrike has also pushed the boundaries of applying AI in cybersecurity to identify and stop the most advanced, emerging attacks. Now, CrowdStrike is leveraging powerful AI techniques to create new IoAs at machine speed and scale.

“CrowdStrike leads the way in stopping the most sophisticated attacks with our industry-leading Indicators of Attack capability, which revolutionized how security teams prevent threats based on adversary behaviour, not easily changed indicators,” said Amol Kulkarni, chief product and engineering officer at CrowdStrike. “Now, we are changing the game again with the addition of AI-powered Indicators of Attack, which enable organizations to harness the power of the CrowdStrike Security Cloud to examine adversary behaviour at machine speed and scale to stop breaches in the most effective way possible.”

The Falcon platform’s new capabilities include:

Industry’s first AI-powered IoAs
Organizations today are under pressure to defend expanding attack surfaces against emerging threats and adversary tradecraft. With the Falcon platform, organizations can:

  • Detect new classes of attacks, faster than ever: Find emerging attack techniques with new IoAs created by continuously learning AI models trained on real-world adversary behaviour and the world’s richest threat intelligence.
  • Drive automated prevention with high-fidelity detections: Shutdown attacks based on a chain of behaviours, irrespective of the specific malware or tools used, with cloud-native AI models constantly delivered to the Falcon agent with newly-found IoAs.
  • Activate IoAs at cloud scale, trained on human-led expertise: Synthesize insights with AI-powered IoAs from CrowdStrike’s world-renowned threat hunting team to minimize false positives, maximize analyst productivity and deploy threat hunting at scale.

Of note, AI-powered IoAs have identified over 20 never-before-seen adversary patterns, which have been validated by experts and enforced on the Falcon platform for automated detection and prevention.

New innovations for fileless attack prevention at scale
According to the 2022 CrowdStrike Global Threat Report, 62% of all attacks are malware-free. These fileless attacks can be carried out entirely in memory, creating a blindspot for threat actors to exploit. With the Falcon platform, organizations can:

  • Prevent the most advanced fileless attacks: Stop advanced persistent threats (APT) and prevalent tools, like Cobalt Strike, with advanced memory scanning techniques that augment best-of-breed AI/ML and IoA detections with lightning-fast scanning of all memory at an unprecedented scale.
  • Leave bloated memory scanning behind: Shed the heavy resource constraints of legacy approaches that made memory scanning a non-starter with high-performance memory scanning techniques, optimized for Intel CPU/GPUs.
  • Initiate memory scans on behaviour, not a fixed schedule: Automate scans with behaviour-based triggers to find and stop fileless attack patterns in real-time, not after a potential breach.

Enhanced visibility for stealthy cloud intrusions
As Linux environments, data and applications have moved to the cloud, adversaries have also moved to the cloud to open backdoors, steal sensitive data and conceal their movement. With the Falcon platform, organizations can:

  • Hunt stealthy rootkits and reduce dwell time: Identify malicious activity early in the kill chain with deep Linux kernel visibility to fuel threat hunting and investigation of hidden, emerging Linux attacks.
  • Bolster managed cloud threat hunting: Disrupt the most sophisticated threats in cloud environments with new kernel telemetry events for Falcon OverWatch experts, building on CrowdStrike’s recently announced Fallon OverWatch Cloud Threat Hunting service.

“Using CrowdStrike sets Cundall apart as one of the more advanced organizations in an industry that typically lags behind other sectors in IT and cybersecurity adoption,” said Lou Lwin, CIO at Cundall. “Today, attacks are becoming more sophisticated and if they are machine-based attacks, there is no way an operator can keep up. The threat landscape is ever-changing. So, you need machine-based defences and a partner that understands security is not ‘one and done.’ It is evolving all the time.”

According to Forrester, “No security tool can detect every attack. Cybersecurity pits adversaries against defenders. Defensive technologies rely on rules, heuristics, and outliers to find evil. Those technologies lack one essential component that threat hunting introduces: the creativity of the practitioners defending enterprise environments.”

These capabilities are generally available for Falcon Prevent (NGAV) and Falcon Insight (EDR) customers.

Preparing a Secure Cloud Environment in the Digital New Norm

Published

Written by Daniel Jiang, General Manager of the Middle East and Africa, Alibaba Cloud Intelligence

As hybrid or remote working is being adopted by many companies globally and becoming the ‘new norm’ for millions of workers, cyberattacks meanwhile continue unabated. Building a secure and reliable IT environment has therefore become an increasingly important priority for many businesses who are exploring opportunities in the global digital economy. While moving to the cloud and using cloud-based security features is a good way to challenge cyber risks, it’s important to delve deeper into how best to construct a secure and reliable cloud environment that can fend off even the most determined attacker.

In today’s digital environment, discussions about cyber security’s best practices have never been more important. The UAE in particular established the Cybersecurity Council to develop a cybersecurity strategy and build a secure cyber infrastructure by creating related regulations. Following this move, the nation ranked 5th place on the International Telecommunications Union’s Global Cybersecurity Index 2020, jumping 33 places and it continues to prioritize cyber security and awareness. Creating a secure cloud environment – from building the architecture to adopting cutting-edge security technologies and putting in place important security management practices – will inspire more thorough conversations on this subject.

A resilient and robust security architecture is essential for creating a cloud environment capable of assuring an organisation about the availability, confidentiality and integrity of its systems and data. From the bottom up, the architecture should include security modules of different layers, so that companies can build trustworthy data security solutions on the cloud layer by layer – from the infrastructure security, data security, and application security to business security layers.

In addition to the security modules of all of the layers, there are a variety of automated data protection tools that enable companies to perform data encryption, visualisation, leakage prevention, operation log management and access control in a secure computing environment. Enterprises can also leverage cloud-based IT governance solutions for custom designs of cloud security systems to meet compliance requirements from network security and data security to operation auditing and configuration auditing. This ensures full-lifecycle data security on the cloud, with controllable and compliant data security solutions in place.

Another consideration is to build a multi-tenant environment, abiding by the principle of least privilege and adopting consistent management and control standards to protect user data from unauthorised access. In addition, establishing strict rules for data ownership and operations on data, such as data access, retention and deletion, is also pivotal in creating a safe environment.

Moreover, enterprises can embrace the zero-trust security architecture and build a zero-trust practice by design to protect the most sensitive systems. The architecture requires everything (including users, devices and nodes) requesting access to internal systems to be authenticated and authorised using identity access protocols. As such, the zero-trust security architecture cuts down on automatic trust, or trust without continuous verification, addressing modern challenges in securing remote working environments, hybrid cloud settings and increasingly aggressive cyber threats.

Cutting-edge security technologies such as comprehensive data encryption, confidential computing and many more emerging tech solutions, can be leveraged to ensure we stay on top of the trends in cybersecurity. Comprehensive data encryption provides advanced data encryption capabilities on transmission links (such as data-in-motion), compute nodes (such as data-in-use), and storage nodes (such as data-at-rest). Key Management Service and Data Encryption Service help users securely manage their keys and use a variety of encryption algorithms to perform encryption operations.

Another emerging technology to safeguard the cloud environment is confidential computing. Confidential computing is dedicated to securing data in use while it is being processed, protecting users’ most sensitive workloads. Confidential computing based on trusted execution environments (TEEs), ensures data security, integrity and confidentiality while simplifying the development and delivery of trusted or confidential applications at lower costs.

It is equally important to adopt proper security management practices and mechanisms to maximise the security protection of one’s critical system and important data. One essential mechanism to protect the cloud environment is to develop a comprehensive disaster recovery system, which enables businesses to configure emergency plans for data centres based on factors such as power, temperature and disasters, and establish redundant systems for basic services such as cloud computing, network and storage. It helps companies to deploy their business across regions and zones and build disaster recovery systems that support multiple recovery models.

Setting the effective reviewing and response mechanism for your cloud security issues is imperative. First, having vulnerability scanning and testing in place is important to assess the security status of systems; second, it is vital to use cloud-native monitoring tools to detect any anomalous behaviour or insider threats; furthermore, establishing proper procedures and responsibility models to quickly and accurately assess where vulnerabilities exist and their severity, will help ensure that quick remedy actions can be taken when security problems emerge.

In the future, developing the security architecture, technologies, management and response mechanism will no longer be perceived as a cost-centre burden for companies, but rather, as critical capabilities to safeguard the performance and security of daily business operations. Crafting a comprehensive cloud security plan, adopting the best industrial practices, and choosing a professional cloud service provider with strong security credentials to work with, should be an imperative subjects in a CXO’s agenda.

Hive, LockBit and BlackCat Ransomware Gangs Consecutively Attack the Same Network: Sophos

Published

on

Sophos, a global leader in next-generation cybersecurity, today announced in the Sophos X-Ops Active Adversary whitepaper, “Multiple Attackers: A Clear and Present Danger,” that Hive, LockBit and BlackCat, three prominent ransomware gangs, consecutively attacked the same network. The first two attacks took place within two hours, and the third attack took place two weeks later. Each ransomware gang left its own ransom demand, and some of the files were triple encrypted.

“It’s bad enough to get one ransomware note, let alone three,” said John Shier, senior security advisor at Sophos. “Multiple attackers create a whole new level of complexity for recovery, particularly when network files are triple encrypted. Cybersecurity that includes prevention, detection and response are critical for organizations of any size and type—no business is immune.”

The whitepaper further outlines additional cases of overlapping cyberattacks, including cryptominers, remote access trojans (RATs) and bots. In the past, when multiple attackers targeted the same system, the attacks usually occurred across many months or multiple years. The attacks described in Sophos’ whitepaper took place within days or weeks of each other—and, in one case, simultaneously—often with the different attackers accessing a target’s network through the same vulnerable entry point.

Typically, criminal groups compete for resources, making it more difficult for multiple attackers to operate simultaneously. Cryptominers normally kill their competitors on the same system, and today’s RATs often highlight bot killing as a feature on criminal forums. However, in the attack involving the three ransomware groups, for example, BlackCat—the last ransomware group on the system—not only deleted traces of its own activity but also deleted the activity of LockBit and Hive. In another case, a system was infected by LockBit ransomware. Then, about three months later, members of the Karakurt Team, a group with reported ties to Conti, were able to leverage the backdoor LockBit created to steal data and hold it for ransom.

“On the whole, ransomware groups don’t appear openly antagonistic towards one another. In fact, LockBit explicitly doesn’t forbid affiliates from working with competitors, as indicated in Sophos’ whitepaper,” said Shier. “We don’t have evidence of collaboration, but it’s possible this is due to attackers recognizing that there are a finite number of ‘resources’ in an increasingly competitive market. Or, perhaps they believe the more pressure placed on a target—i.e. multiple attacks—the more likely the victims are to pay. Perhaps they’re having discussions at a high level, agreeing to mutually beneficial agreements, for example, where one group encrypts the data and the other exfiltrates. At some point, these groups will have to decide how they feel about cooperation—whether to further embrace it or become more competitive—but, for now, the playing field is open for multiple attacks by different groups.”

Most of the initial infections for the attacks highlighted in the whitepaper occurred through either an unpatched vulnerability, with some of the most notable being Log4Shell, ProxyLogon, and ProxyShell, or poorly configured unsecured Remote Desktop Protocol (RDP) servers. In most cases involving multiple attackers, the victims failed to remediate the initial attack effectively, leaving the door open for future cybercriminal activity. In those instances, the same RDP misconfigurations, as well as applications like RDWeb or AnyDesk, became an easily exploitable pathway for follow-up attacks. In fact, exposed RDP and VPN servers are some of the most popular listings sold on the dark web.

“As noted in the latest Active Adversary Playbook, in 2021 Sophos began seeing organizations falling victim to multiple attacks simultaneously and indicated that this may be a growing trend,” said Shier. “While the rise in multiple attackers is still based on anecdotal evidence, the availability of exploitable systems gives cybercriminals ample opportunity to continue heading in this direction.”
