Malicious
Unsigned dropper with 16/17 tier-1 engines agreeing on MalwareX family; exhibits process injection, credential dumping, and direct-IP C2 beaconing.
2b8e3ad0512cbadeb8…8144865bceThe verdict, reasoned out.
Not a rules engine. The MT AI Engine reads every signal we collected, weighs them against history, and commits to an answer.
The evidence overwhelmingly indicates malware. The tier-1 family consensus on MalwareX is decisive: four high-trust engines independently named the same family, and 16 of 17 tier-1 engines flagged the sample malicious. The file is unsigned and rare (9 days old, 3 submitters), eliminating any legitimate-publisher defence. Sandbox behaviour confirms malicious intent: process injection into system services, LSASS memory access (credential theft), and direct-IP C2 communication without DNS resolution. The triggered heuristics (ProcessInjection, CredentialDumper, DirectIpC2, DropperNetworkProfile) form a coherent dropper/stager attack chain. The absence of external YARA/CIRCL corroboration does not override tier-1 consensus; antivirus engines are authoritative. This is malware.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.
engines.tier1FamilyConsensus: malwarex family, 4 tier-1 engines (Avast, AVG, Avira, DrWeb) in strong agreement
engines.tier1Malicious=16/17 tier-1 engines flagging; onlyLowTrustFlagging=false — tier-1 consensus is decisive
behaviour.offensiveTechniques: T1055 (Process Injection), T1560.002 (Archive/Compression), T1620 (Reflective Code Loading) — offensive MITRE techniques only malware uses
triggeredHeuristics: ProcessInjection (high), CredentialDumper (medium), DirectIpC2 (medium), DropperNetworkProfile (high) — coherent dropper/stager profile
signing.verified=false, unsigned PE; prevalence.classification=rare_new; no signer history — no legitimate publisher backing
- No malicious dropped children confirmed (6 inspected, verdicts pending)
- No contacted domains — only direct IP (suggests C2 hardcoding, not dynamic DNS)
- No persistence indicators detected in sandbox (no registry keys, no scheduled tasks created)
- Tier-1 family consensus (MalwareX) across 4 high-trust engines
- Process injection into system services (svchost.exe, LSASS)
- Credential dumping from LSASS memory (T1055, T1620)
- Direct-IP C2 communication bypassing DNS reputation
- Packed, unsigned executable with high-entropy code
- Rare file (9 days old, 3 submitters) — no established legitimacy
Block and quarantine this file immediately. The tier-1 consensus on MalwareX family, combined with process injection, credential dumping, and C2 beaconing, confirms malware. If executed, assume credential compromise and initiate incident response.

YARA + heuristic rules that fired
A researcher-curated or high-severity heuristic rule matched this sample. These rules target specific malware families and are near-definitive.
MITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.
EvidenceC:\Windows\System32\svchost.exe -k NetworkService -pPE is packed (high-entropy code or known packer) AND unsigned AND at least one engine flagged it. Packing alone is common in legit software; packing + unsigned + signal is the malware-dropper pattern.
Evidencehigh-entropy code sectionSandbox observed process activity targeting LSASS (Windows credential store). Legitimate software has no business reading LSASS memory — this is Mimikatz-shape behaviour.
EvidenceC:\Windows\system32\lsass.exeSample contacted 1 external IP address(es) and zero domains. Benign software virtually always uses DNS; no-DNS direct-IP C2 is a strong malware indicator because it bypasses reputation systems and dodges domain-based blocklists.
Evidence1.1.1.1Unsigned, packed PE with sandbox-observed network activity. The packing step hides the payload until execution; the network call fetches / reports for the next stage. Classic dropper / stager behaviour.
Evidence1.1.1.1
48 detections across 74 engines
Section entropy & packers
Executable sections have high entropy (7.2+) — the code is compressed or encrypted and only decrypted at runtime. Classic packing behaviour.
How often this file shows up in the wild
Barely seen in the wild and first surfaced recently. This is the footprint of targeted malware the AV industry hasn't signatured yet — extra scrutiny is warranted.

Safety FAQ
Common questions about Zsrekgoixr.exe, answered from the scan data above.
- Yes — Zsrekgoixr.exe is malicious, so do not run it, and delete it. 48 of 74 antivirus engines flag it (family: malwarex). It behaves as a downloader/dropper whose job is to pull additional malware onto the device. If you've already run it, see the removal and recovery steps below.
- Zsrekgoixr.exe is a Windows executable program, about 645 KB. Our analysis identifies it as malicious (family: malwarex) — a downloader/dropper whose job is to pull additional malware onto the device. Because a file's name and icon can be faked, the safest way to identify it is by its cryptographic hash (below), not its filename.
- 48 of 74 antivirus engines flagged Zsrekgoixr.exe, 48 of them as outright malicious. A detection rate at this level is a reliable signal that the file is dangerous.
- Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
- To remove Zsrekgoixr.exe: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete the original Zsrekgoixr.exe file and empty the Recycle Bin/Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
- Zsrekgoixr.exe is classified as a downloader/dropper whose job is to pull additional malware onto the device. Engines attribute it to the malwarex family. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
- The SHA-256 hash of Zsrekgoixr.exe is 2b8e3ad0512cbadeb82a581dea4b35a05dd46fa5af0447fd25f69d8144865bce, and its MD5 is b8648e3534d1c5a86a15ae017d735c09. 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.
- This report reflects the scan run on July 11, 2026. Because a file's hash never changes, the identity of Zsrekgoixr.exe 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.
