We can confidently classify most incidents with\ncauses before impact (suspicious events, tool alerts, etc.) as ransomware.\n\nVulnerability Exploitation:\nIn all cases when exploiting vulnerabilities was used as the initial vector, \nthe main damage is data encryption.The most prevalent vulnerability in our data set is the list of vulnerabilities related to Microsoft Exchange Server ( CVE-2021-26855 , CVE-2021-34523 , CVE-2021-26855 ,CVE-2021-34523 )\n\nTop initial compromise vectors and how long the attack went unnoticed:\nIn most cases where initial access wasn\u2019t identified, the attack lasted for\nmore than a year before being detected by the organization, by which time\n\nno artefacts were left to analyze due to log rotation policies. More than\nhalf of all attacks that started with malicious e-mails, stolen credentials\nor external application exploitation were detected in hours or days.\n\nLegitimate tools in MITRE ATT&CK\u00ae\nIn most cases, security teams can mitigate the initial vector of attack with\nprevention solutions. The most prevalent vectors of attack (exploitation \nof public-facing applications, compromised accounts, malicious e-mail) could\nhave been mitigated - with timely patch management and implementation \nof multifactor authentication, solutions with anti-phishing software to defend\nagainst phishing attacks, and implementation of security awareness training \nfor employees.\n\n\n-Business Secure Continuity-\n1402.07.23\n\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\n#MDR #NDR #EDR #Malware\n#BusinessSecureContinuity\n\nhttps://www.linkedin.com/feed/update/activity:7119244412445933568", "creation_timestamp": "2026-09-01T17:00:16.770353Z"}
