href=\"https:\/\/www.trendmicro.com\/en_us\/ciso\/21\/k\/ransomware-as-a-service-101.html\">ransomware-as-a-service<\/a>. While these cybercrime syndicates are based on specific motivations, another group, dubbed \u201ccybermercenaries\u201d, has developed to provide cyberattack services, tools, and even training to anyone willing to pay. <a href=\"https:\/\/www.trendmicro.com\/vinfo\/tmr\/?\/us\/security\/news\/cybercrime-and-digital-threats\/the-far-reaching-attacks-of-the-void-balaur-cybermercenary-group\" target=\"_blank\" rel=\"noopener\">Trend Micro Research<\/a> took a deep look into the group\u2019s activities, offerings, targets, and connections, enabling security decision makers to strengthen their defense strategies.<\/b><\/p>\n<p><span class=\"body-subhead-title\">Who is Void Balaur?<\/span><\/p>\n<p>Void Balaur (aka Rockethack), active since 2015, is a threat actor that primarily hacks into the mailboxes of email providers and social media accounts using highly specialized malware such as Z*Stealer and DroidWatcher. They also dabble in cyberespionage and data theft, selling valuable information to whoever\u2019s willing to pay. During our investigation, we determined that Void Balaur had targeted over 3,500 victims, some of which were hit persistently and repeatedly. They tend to target organizations and individuals with large amounts of sensitive data, such as mobile and core telco companies, ATM machines and point-of-sale vendors, and FinTech companies and banks.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"image\">\n<figure class=\"image-figure\"> <img decoding=\"async\" src=\"https:\/\/www.trendmicro.com\/content\/dam\/trendmicro\/global\/en\/ciso\/21\/k\/defend-against-cybermercenary-attacks\/defend-againts-figure1.png\" alt=\"defend-againts-figure1\"> <\/figure>\n<\/p><\/div>\n<div>\n<div class=\"richText\" readability=\"36.720034246575\">\n<div readability=\"20.982876712329\">\n<p><span class=\"body-subhead-title\">Defending against cybermercenary attacks<\/span><\/p>\n<p>By following and learning from the patterns and behaviour of Void Balaur, we can curtail future cybermercenary attacks. These groups have access to a large number of tools and infrastructure, allowing them to launch attacks against prominent targets. However, just because they have a lot of tools, doesn\u2019t mean you need a complicated defense strategy. It\u2019s like using an alarm system to defend your home\u2014it\u2019s effective whether someone tries to break in through a window or a door. The following best security practices can help you thwart cybermercenary attacks:<\/p>\n<ul>\n<li><span class=\"rte-red-bullet\">Choose a reputable email service that is known to have robust security and high privacy standards<\/span><\/li>\n<li><span class=\"rte-red-bullet\">Use two-factor authentication (2FA) apps instead of relying on SMS<\/span><\/li>\n<li><span class=\"rte-red-bullet\">Use end-to-end encryption for all communication<\/span><\/li>\n<li><span class=\"rte-red-bullet\">Regularly delete older messages to minimize the chance of sensitive data ending up in the wrong hands. You can utilize mobile features that automatically delete chats after a certain period of time.<\/span><\/li>\n<\/ul>\n<p>For more insights into Void Balaur, cybermercenaries, and best security practices, read <a href=\"https:\/\/www.trendmicro.com\/vinfo\/tmr\/?\/us\/security\/news\/cybercrime-and-digital-threats\/the-far-reaching-attacks-of-the-void-balaur-cybermercenary-group\" target=\"_blank\" rel=\"noopener\">Void Balaur: Tracking a Cybermercenary\u2019s Actitivites<\/a>.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<section class=\"tag--list\">\n<p>Tags<\/p>\n<\/section>\n<p> <\/main> <\/article>\n<\/div>\n<\/div><\/div>\n<\/div>\n<p> <!-- \/* Core functionality javascripts, absolute URL to leverage Akamai CDN *\/ --> <!--For Modal-start--> <\/p>\n<p> <span>sXpIBdPeKzI9PC2p0SWMpUSM2NSxWzPyXTMLlbXmYa0R20xk<\/span> <\/p>\n<p> <!--For Modal-end--> <!-- Go to www.addthis.com\/dashboard to customize your tools --> <\/body> Read More <a href=\"https:\/\/www.trendmicro.com\/en_us\/ciso\/21\/k\/defend-against-cybermercenary-attacks.html\">HERE<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Explore Trend Micro\u2019s latest research into Void Balaur, a prolific cybermercenary group, to learn how to defend against attacks launched by this growing group of threat actors.
