Technical Breakdown: 1. File Extension & Renaming Patterns Confirmation of File Extension: The DedSec ransomware appends “.dedsec” (case-insensitive, lowercase in most samples, uppercase variations observed) to every encrypted file. Renaming Convention: Files are first encrypted entirely, then renamed in one of two observed patterns: <original_filename>.<original_ext>.dedsec → document.pdf.dedsec <random_hex_string>.<original_ext>.dedsec → A1F32BC8.pdf.dedsec (rotating 6–8-character hex prefix) The…

Technical Breakdown: DEDO Ransomware 1. File Extension & Renaming Pattern Exact extension appended: .dedo (lower-case) Renaming convention: – Encrypted files keep their original basename and existing extension but have .dedo added after the last period → document.pdf.dedo – If the file had no extension, only .dedo is appended → Spreadsheet.dedo 2. Detection & Outbreak Timeline…

Ransomware Resource Sheet Variant: DEDCryptor Technical Breakdown: 1. File Extension & Renaming Patterns Confirmation of File Extension: – The ransomware appends “.ded” to each encrypted file (e.g., report.xlsx → report.xlsx.ded). Renaming Convention: – Files keep their original names intact before the original extension, then “.ded” is added at the end. – No GUID, e-mail address,…

Technical Breakdown: 1. File Extension & Renaming Patterns Confirmation of File Extension {{ $json.extension }} consistently appends “.ded” as a second extension after the original file’s extension. Typical end-state: filename.ext.ded Renaming Convention Both file name and extension are preserved; only .ded is appended. Case-insensitive on NTFS but always lower-case in the wild. Directory traversal is…

Technical Breakdown: DECRYPTIONAL Ransomware 1. File Extension & Renaming Patterns Confirmation of File Extension: .decryptional Renaming Convention: Files are renamed in the pattern {originalName}.{originalExt}.decryptional. Example: Manager_Q3_Report.xlsx becomes Manager_Q3_Report.xlsx.decryptional. No prefixing of attacker e-mail addresses or unique IDs is used, which simplifies batch searches but complicates forensic correlation. 2. Detection & Outbreak Timeline Approximate Start Date/Period:…

decryptiomega Ransomware Resource Guide Cyber-security analyst DRAFT – last updated 2024-06-06 ## Technical Breakdown 1. File Extension & Renaming Patterns • Confirmation of File Extension: .decryptiomega Every encrypted file receives an additional second extension rather than replacement. E.g., Contract_proposal_2024.xlsx becomes Contract_proposal_2024.xlsx.decryptiomega • Renaming Convention: Prefix/path left unchanged. A 48-byte Base64-encoded IV/nonce (64 printable characters) is…

Technical Reference & Community Guide Ransomware Variant: [email protected] (commonly labeled “Tutanota / Dr. Decryptor”) Technical Breakdown 1. File Extension & Renaming Patterns Confirmed file extension appended: [email protected] (i.e., every encrypted file ends with the literal string “[email protected]”). Renaming convention: Original filename+original extension → <original filename>.<original extension>[email protected] Example: QuarterlyReport.xlsx becomes [email protected] 2.

decryptallfiles.txt Ransomware Threat Intelligence Guide Added: 2024-06-XX | Version: 1.0 Contributing analysts: Zero-Day Sentinel Lab, Incident Response Team @ XYZ-CERT Technical Breakdown 1. File Extension & Renaming Patterns Exact extention used: None – “decryptallfiles.txt” itself is not an encrypted-file extension. Instead infected systems will see every original filename unchanged but a new plain-text ransom note…
