They claims that SonicWall products and real-time security services can help companies detect Sunburst and Supernova malware, as well as other attacks on vulnerable systems. Now, it seems, they've fallen victim to a cyber attack themselves, due to a 0-day exploit. German blog reader Stefan A. emailed me this evening to alert me about a cyber security incident &#8211; thanks for the information. Sonicwall has confirmed an cyber attack within <a href=\"https:\/\/www.sonicwall.com\/support\/product-notification\/urgent-security-notice-netextender-vpn-client-10-x-sma-100-series-vulnerability\/210122173415410\/\" target=\"_blank\" rel=\"noopener\">this announcement<\/a> on January 22, 2021. <\/p>\n<blockquote>\n<p>Urgent Security Notice: NetExtender VPN Client 10.X, SMA 100 Series Vulnerability<\/p>\n<p><strong>NOTE:<\/strong> We will continue to update this knowledge base (KB) article as more information and mitigation steps are available.  <\/p>\n<p>SonicWall provides cybersecurity products, services and solutions designed to help keep organizations safe from increasingly sophisticated cyber threats. As the front line of cyber defense, we have seen a dramatic surge in cyberattacks on governments and businesses, specifically on firms that provide critical infrastructure and security controls to those organizations.  <\/p>\n<p>We believe it is extremely important to be transparent with our customers, our partners and the broader cybersecurity community about the ongoing attacks on global business and government.  <\/p>\n<p>Recently, SonicWall identified a coordinated attack on its internal systems by highly sophisticated threat actors exploiting probable zero-day vulnerabilities on certain SonicWall secure remote access products. The impacted products are:  <\/p>\n<ul>\n<li>NetExtender VPN client version 10.x (released in 2020) utilized to connect to SMA 100 series appliances and SonicWall firewalls\n<li>Secure Mobile Access (SMA) version 10.x running on SMA 200, SMA 210, SMA 400, SMA 410 physical appliances and the SMA 500v virtual appliance<\/li>\n<\/ul>\n<p>The NetExtender VPN client and SMB-oriented SMA 100 series are used for providing employees\/users with remote access to internal resources. The SMA 1000 series is not susceptible to this vulnerability and utilizes clients different from NetExtender.<\/p>\n<\/blockquote>\n<p>In the linked article, Sonicwall provides advice on what customers can do as a precaution or what actions they should take in light of the ATP attack.&nbsp; <\/p>\n<ul>\n<li>For Sonicwall SMA 100 series: Block \/ restrict access to SSLVPN service via a firewall (whitelisting).\n<li>For Sonicwall Firewall series: Disable \/ restrict SSLVPN service on firewall (whitelisting).<\/li>\n<\/ul>\n<p>To configure the access, there is <a href=\"https:\/\/www.sonicwall.com\/support\/knowledge-base\/how-to-restrict-access-for-netextender-mobile-connect-users-based-on-policy-for-ip-address\/170502499350337\/\" target=\"_blank\" rel=\"noopener\">this Sonicwall post<\/a>.
