Safe
This unsigned JAR file, labeled as a cracked game client, lacks engine detections but exhibits characteristics typical of high-risk, unauthorized software distributions.
589ce08f5b1c2a9b0a…a3104bfd18The 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.
The sample is an unsigned JAR file with a filename suggesting it is a pirated or modified version of a game client. Although our antivirus engines have not flagged it, the lack of a digital signature and its 'rare_new' status are common indicators of potentially unwanted or malicious software. Such files are frequently used to distribute unauthorized modifications that may contain hidden payloads. Given the lack of behavioral data, we categorize this as suspicious due to the high risk associated with 'cracked' software.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.
filename 'Krypton Client 1.21.11 CRACKED-x64.jar' indicates unauthorized modification or piracy
prevalence.classification is 'rare_new' with only 1 submission
signing.verified is false (unsigned)
engines.malicious is 0/74, indicating no current signature-based detection
filenameAnalysis.looksLikeResearchTool is true, consistent with game-modding or utility-client patterns
- 0/74 engines flagged as malicious
- unsigned file
- rare_new prevalence
- cracked software naming convention
- potential for bundled unwanted software

Safety FAQ
Common questions about Krypton Client 1.21.11 CRACKED-x64.jar, answered from the scan data above.
- Krypton Client 1.21.11 CRACKED-x64.jar 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.
- Krypton Client 1.21.11 CRACKED-x64.jar is a file (application/java-archive), about 7.8 MB. 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 Krypton Client 1.21.11 CRACKED-x64.jar 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 Krypton Client 1.21.11 CRACKED-x64.jar is 589ce08f5b1c2a9b0a24950768e63806e741987dc796b364dd3bd8a3104bfd18, and its MD5 is 95ee3ed35225d4839f7762a76a397ed3. 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 — Krypton Client 1.21.11 CRACKED-x64.jar 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 21, 2026. Because a file's hash never changes, the identity of Krypton Client 1.21.11 CRACKED-x64.jar 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.
