Safe
Zero detections from 63 reporting engines on a newly submitted unsigned PDF.
6ac88ebdff5d035d57…4647ab9d43The reasoning behind this verdict
The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.
Complete engine silence across both high-trust and low-trust tiers indicates the sample is not recognised as malicious by our antivirus network. The PDF format itself carries no executable risk unless a zero-day exploit is present, and no such signals appear in the payload. Absence of YARA rules, CIRCL hits, and RAG matches further supports a clean assessment. The only remaining uncertainty is the file's extreme newness and lack of sandbox execution data.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.
engines.malicious=0 with tier1Malicious=0 across 17 tier-1 engines (Avast, AVG, Avira, BitDefender, DrWeb, Emsisoft, ESET-NOD32, F-Secure, Fortinet, GData, Ikarus, Kaspersky, Microsoft)
prevalence.classification=rare_new with uniqueSources=1 and timesSubmitted=1
signing.signed=false and signerStats.found=false
externalIntel.yaraify.ruleCount=0 and externalIntel.circl.hit=false
- Zero malicious detections from tier-1 engines
- No YARA or CIRCL matches
- No sandbox or network indicators
Treat as safe for normal use; monitor for any future engine updates that might retroactively flag the sample.

Safety FAQ
Common questions about APPOINTMENT LETTER.pdf, answered from the scan data above.
- APPOINTMENT LETTER.pdf appears safe. 74 of 74 antivirus engines report it clean. As a habit, only open files you downloaded from the official source, since attackers sometimes distribute trojanised copies of legitimate software under the same name.
- APPOINTMENT LETTER.pdf is a document file (application/pdf), about 199 KB. Our analysis found no threat indicators for it. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
- None — all 74 antivirus engines we queried report APPOINTMENT LETTER.pdf as clean. That's reassuring, though brand-new malware can briefly evade detection before vendors add signatures, so we also weigh the file's behaviour and reputation.
- The SHA-256 hash of APPOINTMENT LETTER.pdf is 6ac88ebdff5d035d576cc43b9eaa08602abc14094915e49c4ef53c4647ab9d43, and its MD5 is 92fe3353ffc011072b09484f65d8e72c. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
- Based on this scan, yes — APPOINTMENT LETTER.pdf shows no threat indicators. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it while we report it clean, that is most often a false positive, but verify the source before overriding your antivirus.
- This report reflects the scan run on July 18, 2026. Because a file's hash never changes, the identity of APPOINTMENT LETTER.pdf is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
