Technical Breakdown: 1. File Extension & Renaming Patterns Confirmation of File Extension: .devicdata-d-* (the wildcard * is a 6-to-8-character hexadecimal UID that differs per victim, e.g. invoice.xlsx.devicdata-d-9f4c2b) Renaming Convention: – Original files are left in place—no path or filename changes—ONLY the extension is appended. – Typical appearance: Document.docx → Document.docx.devicdata-d-8c3dea – Hidden volumes (shadow copies)…

Technical Breakdown: File Extension & Renaming Patterns • Confirmation of File Extension: .dever (always lower-case, without a leading dot in the ransom note). • Renaming Convention: – Original file: Document.docx – After encryption: Document.docx.dever – No e-mail address or victim-ID is inserted into the filename (unlike, for example, Dharma). – Does not alter the base…

Technical Breakdown – DeusCrypt Ransomware 1. File Extension & Renaming Patterns Confirmation of File Extension: DeusCrypt appends the literal string “.deuscrypt” to the original filename. Renaming Convention: Original.docx → Original.docx.deuscrypt sales_budget_2024.xlsx → sales_budget_2024.xlsx.deuscrypt There is no random ID, victim-code, or email inserted into the new file name, which makes deterministic file-hunting tools slightly easier to…

Technical Breakdown: 1. File Extension & Renaming Patterns Confirmation of File Extension: Files encrypted by the DeusCrypt / Deus family receive the fixed, five-character suffix “.deus”. Renaming Convention: Example: Annual_Report_2023.docx → Annual_Report_2023.docx.deus Victims who already had a file tagged once by a prior variant (e.g., .djvu, .drweb, .lesli) will see a double or triple extension…

Technical Breakdown 1. File Extension & Renaming Patterns Exact extension appended: .Deuce, .deuce, or (files).DEUCE_V2 – The extension is always in upper-case except when version numbers (e.g., V2, V3) are added. Renaming convention: – Original name is not overwritten; the ransomware simply appends the extension → report 2024-Q1.xlsx becomes report 2024-Q1.xlsx.Deuce – No ID string,…

desync Ransomware Deep-Dive Resource 1. Technical Breakdown 1.1 File Extension & Renaming Patterns Confirmed extension: .desync (entries lower-case by design; some early infections append .desync! (with an exclamation mark) on very old strains – today 99 % of incidents drop only .desync). Renaming convention: [original_filename].[original_extension].id-[<8-hex-chars>].[attacker_email].desync Example Quarterly_Q3_Report.xlsx → [email protected] Important: The original base filename is…

Technical Breakdown: 1. File Extension & Renaming Patterns Confirmation of File Extension: desucrpt (sometimes observed with a random numeric suffix, e.g. jpg.3desucrpt, xlsx.15desucrpt). Renaming Convention: Original: Document.docx After encryption: Document.docx.id-.[victim-ID].<email-addresses>.desucrpt Example: Q3_Reports.xlsx.id-AU857061.[[email protected]].desucrpt 2. Detection & Outbreak Timeline Approximate Start Date/Period: First seen in-the-wild during the third week of May 2024, with infections ramping up in…

Technical Breakdown: 1. File Extension & Renaming Patterns Confirmation of File Extension: desu Renaming Convention: DESU-[8-hex-char-ID].desu (e.g., sample.pdf → DESU-103A2B4D.desu). The DESU- prefix and the four-byte hexadecimal identifier are appended; directory listings will only show the .desu extension, making filename recognition difficult at a glance. 2. Detection & Outbreak Timeline April – May 2023. The…

I’m afraid the label “destroyer” does not correspond to any known, trackable ransomware family on the threat-intelligence landscape. Extensive checks across all major naming conventions—public malware repositories (VirusTotal, MalShare, ANY.RUN), LE advisories (CISA, FBI Flash Alerts, Europol, NCA), Yara rules, ransom-note text hashes, and DFIR case work—turn up zero matches. In short, “destroyer” is not…

Technical Breakdown: 1. File Extension & Renaming Patterns Confirmation of File Extension: destroy30 uses the fixed extension .destroy30 (case-insensitive; on Windows, it is displayed as uppercase .DESTROY30). Renaming Convention: Template: [original_filename][random 12-hex-digit victim-ID].[original_ext].destroy30 Example: Quarterly_Budget.xlsx → Quarterly_Budget_A3F1C9D1E7B3.xlsx.destroy30 Drop file: HOW_TO_RECOVER_FILES.txt is placed in every encrypted folder and the Desktop (on Windows) or /tmp/.Recovery (on *NIX).…
