The increase in digitization, the expansion of remote access, the migration to cloud services and the constant pressure on IT teams create a context in which the attack surface is continuously expanding, and errors \u2013 human or technical \u2013 are inevitable. <\/p><p>In 2024, the cyber threat landscape in Romania became more aggressive, a trend confirmed in 2025 as well. DNSC data <strong><a href=\"https:\/\/www.dnsc.ro\/vezi\/document\/dnsc-raport-anual-2024\" target=\"_blank\" rel=\"noopener\">DNSC data<\/a><\/strong> shows an explosion of malware (+286.8%) and an increase in ransomware attacks mainly targeting legal entities. Cyber fraud (+40.2%), brute-force attacks (+30%) and compromised account incidents also increased, signaling an increase in automated attacks. At the same time, supply chain attacks (including Advanced Persistent Threat) are increasingly targeting employees with extended privileges.  <\/p><p>The three incidents analyzed in this article \u2013 two ransomware attacks (one classic and one fileless) and a case of data exfiltration carried out by a former employee \u2013 are different in terms of attack vector, complexity and immediate impact. Taken together, however, they paint a clear picture of the types of risks faced by modern organizations, the conditions that make these incidents possible, and the importance of a professional, documented, and ethical response. <\/p><h3>Security incidents analyzed in the article<\/h3><p><strong>1 \u2013 Ransomware attack on the authentication and remote access infrastructure<\/strong><\/p><p style=\"padding-left: 40px;\">The incident consisted of a ransomware attack, initially discovered as a result of complaints from users, who reported the inability to access internal resources and authentication problems. Following these reports, it was found that the authentication infrastructure (Active Directory) was affected, as well as the remote access services (VPN). The incident was identified about a day after the initial compromise.  <\/p><p><strong>2 \u2013 Data exfiltration carried out by a former employee (insider threat)<\/strong><\/p><p style=\"padding-left: 40px;\">The incident concerned a data exfiltration action, carried out by a former employee, with a direct impact on the confidentiality of the company&#8217;s information. The starting point of the investigation was a suspicion raised by the organization&#8217;s management, which appeared shortly after the resignation of an employee who had access to sensitive information, there being the premises of an exfiltration carried out before the termination of contractual relations. <\/p><p><strong>3 \u2013 Fileless ransomware attack with major operational impact<\/strong><\/p><p style=\"padding-left: 40px;\">The incident was a fileless ransomware attack, discovered by the IT department as a result of major malfunctions in the operational activity. Active Directory infrastructure, workstations used at cash registers, as well as systems belonging to the finance and IT departments were affected. The incident was identified about two days after the compromise.  <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-099e612 e-flex e-con-boxed e-con e-parent\" data-id=\"099e612\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-9590966 elementor-widget elementor-widget-image\" data-id=\"9590966\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"780\" height=\"521\" src=\"https:\/\/safetech.ro\/wp-content\/uploads\/2023\/11\/shutterstock_1050436496-1024x684.webp\" class=\"attachment-large size-large wp-image-19629\" alt=\"incidente critice de securitate \/ critical cyber security incidents\" srcset=\"https:\/\/safetech.ro\/wp-content\/uploads\/2023\/11\/shutterstock_1050436496-1024x684.webp 1024w, https:\/\/safetech.ro\/wp-content\/uploads\/2023\/11\/shutterstock_1050436496-300x200.webp 300w, https:\/\/safetech.ro\/wp-content\/uploads\/2023\/11\/shutterstock_1050436496.webp 1200w\" sizes=\"(max-width: 780px) 100vw, 780px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a95410f elementor-widget elementor-widget-text-editor\" data-id=\"a95410f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p> <\/p><p>In all these cases, the affected companies contacted Safetech Innovations to ensure a specialized investigation and a coordinated response to the incident, capable of limiting the impact and identifying the real causes of the compromise.<\/p><p><strong>The role of the Safetech Innovations team was not limited to technical intervention, but covered the entire incident management cycle: detection, propagation limiting, forensic investigation, identification of the real causes and implementation of measures to prevent similar incidents.<\/strong><\/p><h3>Types of incidents and associated risks<\/h3><p>Statistics on the incidence of types of attacks differ greatly from region to region. For example, among the most common incidents mitigated by <strong><a href=\"https:\/\/www.msspalert.com\/top-250-2025\" target=\"_blank\" rel=\"noopener\">Top 250 MSSP companies, published by MSSP Alert<\/a><\/strong>, in which Safetech Innovations is included, are email phishing (96%), vulnerability exploitation (94%), ransomware (92%), data leaks and brute force attacks, reported by 85% and 80% of managed service providers, respectively. <\/p><p>The three cases we analyze illustrate three major categories of cyber threats:<\/p><p style=\"padding-left: 40px;\">1. <strong>Ransomware attacks with an impact on availability<\/strong>, as happened in the first and third incidents, where critical infrastructure components such as Active Directory, VPN or operational stations were affected.<\/p><p style=\"padding-left: 40px;\">2. <strong>Insider threats<\/strong>, exemplified by the second incident, in which an employee exfiltrated sensitive data.<\/p><p style=\"padding-left: 40px;\">3. <strong>Advanced, hard-to-detect attacks<\/strong>, such as fileless ransomware, which leave no classic traces on the disk and rely on legitimate operating system tools.<\/p><p>The risks generated by such incidents go beyond the technical area. They include direct financial losses (e.g. seizure of cash registers in incident 3), reputational damage, legal and compliance risks, but also loss of trust of customers and partners. <\/p><h3>The context of the discovery: from weak signals to major malfunctions<\/h3><p>A common element of the three security incidents is that the discovery was not the result of immediate automatic detection, but of <strong>operational signals or human suspicion<\/strong>.<\/p><p>In the first incident, the ransomware attack was only noticed when users were no longer able to log in and access internal resources. In the third case, major dysfunctions in daily activity led the IT department to suspect a complex attack. In the second incident, suspicion came from the management area, amid the recent resignation and previous access to sensitive information.  <\/p><p>This context underscores an uncomfortable reality: many organizations learn that they have been compromised after the impact becomes visible, not in the initial phase of the attack. <strong>The lack of continuous monitoring, advanced log correlation, or mature early detection processes creates windows of time in which attackers can act unhindered.<\/strong><\/p><p>For example, according to the <strong><a href=\"https:\/\/www.ibm.com\/reports\/data-breach#\/pdf\" target=\"_blank\" rel=\"noopener\">Cost of a Data Breach Report 2025<\/a><\/strong> conducted by the Ponemon Institute for IBM, the average time it takes for organizations to identify and contain a security breach is 241 days. On the other hand, for organizations that use advanced threat intelligence and automation capabilities, this interval is significantly reduced, by up to 28 days. The same report also highlights a direct correlation between the time it takes to identify and fix a breach and the total cost generated by it: the faster an incident is detected and limited, the considerably lower the financial impact on the organization.  <\/p><h3>What made these incidents possible?<\/h3><p>The unitary analysis of the three cases indicates a set of recurrent favoring factors:<\/p><p style=\"padding-left: 40px;\">\u2022 <strong>The human factor<\/strong>, either in the form of phishing (incident 1) or in the form of a dissatisfied or uncontrolled employee at offboarding (incident 2).<\/p><p style=\"padding-left: 40px;\">\u2022 <strong>Insufficiently mature security controls<\/strong>, including lack of effective DLP policies, incomplete patch management, or limited remote access monitoring.<\/p><p style=\"padding-left: 40px;\">\u2022 <strong>Over-reliance on existing infrastructure<\/strong> without regular risk reassessments, especially in the context of organisational or technological change.<\/p><p style=\"padding-left: 40px;\">\u2022 <strong>Attacks that exploit legitimacy<\/strong>, such as the use of a compromised domain of a legitimate institution in the fileless attack in incident 3, making detection more difficult.<\/p><p>None of these incidents were the result of a single mistake. They emerged at the intersection of people, processes, and technology. <\/p><h3>Safetech&#8217;s role in detection and impact limitation<\/h3><p>In all three situations, Safetech Innovations&#8217; intervention followed a structured approach that was proportionate to the severity of the incident. The first measures aimed at limiting the spread and stabilizing the infrastructure, by isolating the affected systems, temporarily restricting VPN access or suspending certain critical services. <\/p><p><strong>An essential aspect was to avoid impulsive actions that could have destroyed evidence or aggravated the situation. For example, in the case of insider threat, the workstation was isolated without being tampered with, to allow for a legally valid forensic analysis. <\/strong><\/p><p>This stage of containment is often underestimated, but it makes the difference between a controlled incident and one that escalates rapidly.<\/p><h3>The investigation: what was analyzed and what was discovered?<\/h3><p>The investigations carried out by the Safetech team combined detailed technical analysis with compliance with ethical and legal standards.<\/p><p>In ransomware incidents, VPN logs, Active Directory events, local artifacts, and persistence mechanisms were analyzed. In the first case, the investigation indicated a classic phishing chain &#8211; credential compromise &#8211; ransomware execution. In the third, the complexity was higher, with the attack being fileless and delivered through a seemingly legitimate domain.  <\/p><p><strong>In the case of data exfiltration, the investigation was one with legal potential, carried out in strict compliance with the principles of chain of custody. Analysis of Office 365 logs, USB device usage, and SFTP transfers confirmed the exfiltration of sensitive information. <\/strong><\/p><h3>Remediation and Controlled Restore<\/h3><p>The fix was not limited to &#8220;cleaning&#8221; the systems. In all cases, this involved restoring from secure backups, resetting compromised credentials, validating infrastructure integrity, and resuming operations in a controlled manner. <\/p><p>A common principle applied by Safetech was that fast recovery should not compromise security. It is better to perform a gradual and verified restart than a hasty restart that leaves doors open for the attacker. <\/p><p><strong>The three incidents generated a coherent set of improvements to prevent recurrence:<\/strong><\/p><p style=\"padding-left: 40px;\">\u2022 stricter patch management and hardening policies;<\/p><p style=\"padding-left: 40px;\">\u2022 implementing or strengthening DLP solutions;<\/p><p style=\"padding-left: 40px;\">\u2022 review of offboarding procedures;<\/p><p style=\"padding-left: 40px;\">\u2022 continuous monitoring and advanced correlation of events;<\/p><p style=\"padding-left: 40px;\">\u2022 awareness and training programs for users.<\/p><p><strong>However, these measures were not proposed independently, but part of a continuous process of increasing security maturity.<\/strong><\/p><h3>Conclusions and recommendations<\/h3><p><strong>Taken together, the three incidents demonstrate that cybersecurity is not a product, but a process. The attacks differ, but the lessons are the same: prevention, early detection and professional response are essential. <\/strong><\/p><p>Organizations must accept that incidents can occur, but the way they are managed makes the difference between a major crisis and a controllable event. The involvement of a specialized team, such as Safetech Innovations, ensures not only the technical resolution of the problem, but also the deep understanding of the causes and the transformation of an incident into an opportunity to strengthen cyber resilience, also required by current regulations such as the NIS2 Directive. <\/p><p>For more information about Safetech Innovations&#8217; <strong><a href=\"https:\/\/safetech.ro\/en\/services\/cybersecurity-operations-outsourcing\/soc-outsourcing-services\/\">cybersecurity incident detection and response services<\/a><\/strong>, as well as <strong><a href=\"https:\/\/safetech.ro\/en\/services\/advanced-analysis-critical-cyber-security-incidents\/\">advanced analysis for critical security incidents<\/a><\/strong>, you can contact us at sales@safetech.ro or by phone at +40 21 316 0565.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Three security incidents analysed paint a picture of the types of current risks and the importance of prevention, detection and professional response measures.<\/p>\n","protected":false},"author":2,"featured_media":21551,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[101],"tags":[103,106,110,140],"class_list":["post-29446","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-technology-news","tag-cert-en","tag-monitoring-and-response","tag-risk-management","tag-safetech-results"],"_links":{"self":[{"href":"https:\/\/safetech.ro\/en\/wp-json\/wp\/v2\/posts\/29446","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/safetech.ro\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/safetech.ro\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/safetech.ro\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/safetech.ro\/en\/wp-json\/wp\/v2\/comments?post=29446"}],"version-history":[{"count":5,"href":"https:\/\/safetech.ro\/en\/wp-json\/wp\/v2\/posts\/29446\/revisions"}],"predecessor-version":[{"id":29452,"href":"https:\/\/safetech.ro\/en\/wp-json\/wp\/v2\/posts\/29446\/revisions\/29452"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/safetech.ro\/en\/wp-json\/wp\/v2\/media\/21551"}],"wp:attachment":[{"href":"https:\/\/safetech.ro\/en\/wp-json\/wp\/v2\/media?parent=29446"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/safetech.ro\/en\/wp-json\/wp\/v2\/categories?post=29446"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/safetech.ro\/en\/wp-json\/wp\/v2\/tags?post=29446"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
