New Phishing Scheme Targets Crypto Users Worldwide

Published

on

Kaspersky has unearthed a phishing campaign targeting cryptocurrency users across the globe. The scheme showcases the ever-evolving tactics used by cybercriminals, reflecting cryptocurrency’s increasing appeal. During the spring of 2023 alone, Kaspersky’s solutions detected and thwarted over 85,000 scam emails, encompassing both hot and cold wallets. Kaspersky provides an in-depth report revealing the intricacies of these two distinct email attack techniques and enlightening the differences in hot and cold cryptocurrency storage methods.

With over 400,000,000 cryptocurrency wallet owners globally, as reported by Crypto.com, the spike in the popularity of hot wallets comes from their accessible nature. Online storage services such as crypto exchanges and dedicated apps have become prime targets for cybercriminals due to their constant internet connectivity.

Phishing attacks aimed at hot wallet users typically employ relatively simple tactics, often exploiting non-technical individuals. Malicious actors impersonate well-known crypto exchanges through fraudulent emails, urging users to validate transactions or reconfirm the security of their wallets. Unsuspecting victims who click on the links are redirected to fake web pages that prompt them to enter their seed phrase — an essential element for wallet recovery. By gaining access to the seed phrase, scammers can seize control of the victim’s wallet and transfer funds to their own accounts.

In contrast, cold wallets are entirely offline storage systems, like a dedicated device or even a private key jotted down on paper. Hardware wallets are a prevalent type of cold wallet. They have garnered favour among users storing substantial cryptocurrency holdings due to their enhanced security measures. However, Kaspersky researchers recently discovered a targeted phishing campaign specifically tailored to exploit cold wallet owners. This campaign is initiated with an email masquerading as a prominent cryptocurrency exchange, Ripple, enticing recipients with the promise of participating in an XRP token giveaway.

Instead of directing victims to a phishing page, scammers employ a more sophisticated technique by creating a deceptive blog post that mimics the Ripple website’s design. This blog offers users the chance to enter a giveaway of XRP tokens, the platform’s internal cryptocurrency, by following a specified link. After following the link to a fake Ripple page using a domain name that closely resembles the official Ripple domain (a Punycode phishing attack), victims are prompted to connect their hardware wallets, such as Trezor or Ledger, to the scam website. This interaction allows scammers to gain access to victims’ accounts and initiate fraudulent transactions.

As of spring 2023, Kaspersky’s antispam solutions successfully detected and blocked over 85,000 scam emails aimed at cryptocurrency users. This nefarious campaign reached its peak in March, with more than 34,000 intercepted malicious messages. Kaspersky continued safeguarding cryptocurrency users in April and May, thwarting roughly 19,902 and 30,816 scam emails in these months, respectively.

“We are witnessing an ongoing surge in the popularity of cryptocurrencies, and with it, the need for users to stay alert and implement strong security measures to protect their digital assets. It is crucial to verify the authenticity of the sender and exercise caution before clicking on any links or providing sensitive information,” comments Roman Dedenok, a security expert at Kaspersky.

Sophos Boosts Firewall with New Protection and Incident Response Features

Published

on

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.
