NETSCOUT Highlights Cyberthreats to Watch Out for in 2023

Published

2 years ago

on

NETSCOUT has revealed its top security trends to watch out for in 2023. Based on recent data, the company has predicted that geopolitical unrest, the evolution of ransomware, and the growing popularity of Adaptive DDoS, Direct-Path DDoS, and Outbound and Cross-bound DDoS attacks will have a significant impact on the security industry in 2023.

Emad Fahmy, Systems Engineering Manager Middle East at NETSCOUT, explained, “In the world of cybercrime, innovation is a constant. By constantly innovating and adapting, attackers are designing new, more effective attack vectors or doubling down on existing effective methodologies. Although the future is always difficult to predict, one thing is certain, cyber-attacks will not subside. Moreover, when it comes to cyber-attacks, no business sector is off-limits. Cybercriminals target regional businesses of all sizes and in all sectors, whether public or private.”

Geopolitical Unrest
Although distributed denial-of-service (DDoS) attacks have steadily increased over the past 20 years, recent data firmly establishes the reality that network operators need to understand, prepare for, and expect attacks related to politics, religion, and ideology. Nation-state actors often directly target internet infrastructure to take out critical communications, e-commerce, and other vital infrastructure dependent on internet connectivity. This, of course, means targeting internet service provider (ISP) networks to limit internet connectivity.

Further, nation-states typically possess vastly greater resources at their disposal than other malicious actors. Every year, they create new DDoS attack vectors, proving that they are constantly innovating and exploring new, more potent attack methods. As DDoS defenses become more precise and effective, attackers continue to develop new DDoS attack vectors and methodologies to circumvent these defenses. These advanced techniques invariably find their way into the hands of criminal gangs and even individual hackers, who turn them against any entity from whom they can profit.

Ransomware
Ransomware attacks have posed a significant threat to businesses and individuals in recent years and will continue to evolve and become more sophisticated in 2023. One trend that will continue to evolve is the use of ransomware in combination with other attacks, such as supply chain attacks. It is also likely that malicious actors will continue to target specific industries or types of organizations with ransomware attacks, specifically to maximize their profits. For example, hospitals and other healthcare organizations have been particularly vulnerable to ransomware attacks in the past because, with lives at stake, they may be more willing to pay a ransom to regain access to critical systems and data.

Another ransomware trend that will continue in 2023 is the use of triple extortion attacks. These campaigns begin by infiltrating a network and stealing valuable assets, such as trade secrets, source codes, credit cards, authentication credentials, and other personally identifiable information (PII). In phase two, ransomware is planted to encrypt valuable data or even entire storage systems. At this point, cybercriminals will demand a ransom in exchange for decryption keys. If the victim refuses to pay the ransom, perhaps because they could simply restore good backups, the threat actors then threaten to release sensitive data publicly if the ransom is not met.

This form of attack has been around for several years and can add additional pressure on the victim because the potential repercussions of the data being released to the public can be severe. While the first two actions can be invisible to the public, the third phase cannot escape publicity. Finally, a DDoS attack or even the threat of such turns the pressure up to the max. If the ransom is not paid, DDoS can take down an organization’s internet presence, thus exposing the entirety of the security threat and failure to protect valuable assets.

Adaptive DDoS
In an adaptive DDoS attack, adversaries conduct extensive pre-attack reconnaissance to identify specific elements of the service delivery chain to target. They are increasingly employing botnet nodes and reflectors/amplifiers that are closer to the target, a trend recently observed in botnet attacks on Ukraine. This minimizes the number of boundaries that DDoS attack traffic must traverse, often resulting in fewer opportunities to detect and mitigate the attack. The combination of increased available bandwidth and throughput increased populations of abusable devices, and adaptive DDoS attack techniques magnify the threat to network operators. As such, network operators should move from a default posture of DDoS mitigation to a new posture of DDoS suppression.

Direct-Path DDoS Attacks
Direct flooding and application-layer DDoS attacks are becoming more popular as anti-spoofing efforts increase globally, making it more difficult for spoofed packets to travel across the internet. Old techniques have become popular again as this methodology returns from the past, back before reflection/amplification attacks dominated the landscape. Enhanced for the modern network, these attacks now come from much more powerful sources, such as cloud-based infrastructure with massive computing and bandwidth resources. Further, adversaries are compromising hosts much closer to the target, thus avoiding many layers of transit, potential discovery, and mitigation. Because of this, organizations must beware of the enemy within.

Outbound and Cross-bound DDoS Attacks
Those are not the only threats coming from within – DDoS attack traffic is increasingly originating from within the network it is targeting, thus avoiding ingress and transit points. DDoS defenses traditionally have been focused on protecting internet properties and networks by implementing detection and mitigation technologies at points of convergence for inbound network traffic. This approach worked well to protect targeted organizations and networks from inbound DDoS attacks; however, outbound and cross-bound DDoS attacks can be just as devastating and disruptive as inbound attacks. Because of adversary innovation and adaption, defenders must change their way of thinking and, in turn, adapt to the current threat landscape.

By

Sophos has announced a significant update to its Sophos Firewall software, introducing enhanced protection and incident response capabilities. This update notably includes Sophos NDR Essential, a new feature now available free of charge to all customers holding an XStream Protection license for Sophos Firewall.

This integration empowers Sophos Firewall with two dedicated artificial intelligence (AI) engines specifically designed to detect both malware communications and those utilizing algorithmically generated domain names. This advanced functionality, derived from the Sophos Network Detection and Response (NDR) probe, aims to identify sophisticated malware communications even if they are previously unknown or not yet indexed. It serves as a powerful complement to the Active Threat Response capabilities already embedded within Sophos firewalls.

Chris McCormack, Senior Product Marketing Manager at Sophos

Addressing the technical demands of such advanced detection, Chris McCormack, Senior Product Marketing Manager at Sophos, explained the strategic approach, “NDR traffic analysis requires substantial processing power. That’s why we’ve adopted a new approach by deploying an NDR solution in Sophos Cloud to offload the heaviest tasks from the firewall.” This cloud-centric design ensures optimal performance without burdening the firewall’s on-device resources.

Beyond network detection, the update also brings significant improvements to connectivity and user authentication. Sophos Connect now integrates EntraID for Single Sign-On (SSO). This new feature for the VPN client, bundled with Sophos Firewall, is set to enhance both the security and user experience for SSL and IPsec VPN connections. The integration with EntraID (Azure AD) enables users to authenticate and leverage multi-factor authentication for both Sophos Connect and access to the user portal hosted by the firewall, streamlining secure access.

Further VPN-related enhancements include:

  • Improved user interface and usability: Connection types have been renamed for greater clarity, with “site-to-site” now referred to as “policy-based” and tunnel interfaces as “route-based,” making configurations more intuitive.
  • Dynamic validation of the IP address pool: For VPN connections (SSL VPN, IPsec, L2TP, and PPTP), the system now dynamically validates the allocated IP address pool, helping to better resolve potential IP address conflicts.
  • Strict profile enforcement: IPsec profiles now exclude default values to ensure algorithm synchronization, effectively eliminating potential fragmentation of session negotiation packets that could otherwise prevent site-to-site VPN tunnels from being established.
  • Route-based VPN and SD-RED scalability: The system has been optimized to support up to 3,000 simultaneously established tunnels. Specifically, Sophos Firewall solutions can now manage up to 1,000 SD-RED site-to-site tunnels and connect up to 650 concurrent SD-RED devices.

Additional management improvements enhance administrative flexibility and search capabilities:

  • More flexible DHCP Prefix Delegation (IPv6 DHCP-PD): The system now supports a broader range of prefixes, from /48 to /64, improving compatibility with various internet service providers.
  • Router Advertisement (RA) and DHCPv6 server: These features are now enabled by default, simplifying IPv6 network setup.
  • Resizable table columns: The web admin interface continues its adaptation for ultra-wide screens, with many configuration pages now allowing users to resize columns as needed for improved usability.
  • Enhanced object search functionality: The search field within the SD-WAN routing configuration screen now supports more granular criteria, including route name, ID, objects, and object values like IP addresses and domains. Similarly, local ACL rules now also support object name and value searches, extending to content-based searches for more precise results.
  • Default configuration changes: To streamline initial setups, default firewall rules and rule groups previously created during new firewall deployments have been removed. The initial configuration now only includes the default network rule and MTA rules. Furthermore, the default firewall rule group and the default gateway probe for custom gateways are now set to “None” by default.

Sophos continues its commitment to cybersecurity through a “Secure by Design” approach, enhancing the intrinsic security of its firewalls. This methodology involves the containerization of specific features and rigorous integrity checks on critical operating system files using mathematical checksums. Any detected checksum mismatch triggers a potential compromise alert, enabling monitoring teams to proactively identify possible security incidents affecting the firewall OS integrity. This proactive detection allows incident response and development teams to react swiftly to critical security events.

This update is now available for manual download and deployment by customers with any Sophos Firewall equipped with a valid license.
