Is OperaInstaller.exe safe?
A lone WrappedOpera detection is insufficient alone, but the untrusted signer, revoked-certificate tag, suspicious affiliate host, and offensive runtime mappings warrant caution.
Only 1 of 74 engines flagged this installer, naming WrappedOpera adware, while most high-trust engines remained silent. However, its untrusted signer, revoked-certificate tag, contact with a suspicious affiliate host, and credential-access or injection mappings make it unsuitable to run without verification.

Before running
Do not run it until the source and publisher can be verified independently.
If you already ran it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Only 1 of 74 engines flagged this installer, naming WrappedOpera adware, while most high-trust engines remained silent. However, its untrusted signer, revoked-certificate tag, contact with a suspicious affiliate host, and credential-access or injection mappings make it unsuitable to run without verification.
GData is the only one of 74 engines to detect the file, and there is no strong family consensus. One completed sandbox run mapped credential access, browser-data access, process injection, and security-control impairment, although it did not issue a malicious sandbox verdict and some mappings may overstate ordinary installer artifacts. The installer contacted work.ink, which is recorded as suspicious, but host-reputation coverage did not include every observed IP and URL. Its signature is attributed to Alexis Sreckovic rather than a trusted Opera publisher, verification is unresolved, and the sample carries a revoked-certificate tag. No inspected child, curated intelligence source, or research rule independently confirms malware, leaving materially mixed evidence.
What We Detected
GData was the only engine among 74 to flag the sample, identifying Win32.Adware.WrappedOpera.A. The other 16 reporting tier-1 engines did not detect it, so there is no strong antivirus-family consensus. The executable is signed by Alexis Sreckovic, but signing verification is unresolved, the publisher is not trusted in the available history, and the file carries a revoked-certificate tag.
Threat Behavior
One sandbox run mapped MITRE techniques including T1003, T1055, T1555.003, and T1562.001. These suggest possible credential access, process injection, browser-data access, and interference with security controls, although the sandbox itself issued no malicious verdict and some synthesized mappings rely on artifacts that can occur during browser installation. The file also contacted work.ink, a host scored as suspicious. Because only five hosts were checked while additional IPs and URLs were observed, a complete network-reputation assessment is unavailable.
What To Do Now
Do not launch this copy unless its origin and signature can be independently verified. Delete it and download Opera directly from the official vendor channel instead; keep endpoint protection enabled and scan the system if this installer has already run.
Where this verdict could be wrong4 caveats
- Sixteen of 17 reporting tier-1 engines did not flag the file, and GData is the only engine reporting WrappedOpera.
- behaviour.hasMaliciousSandboxVerdict=false, despite the offensive-technique mappings.
- All 10 inspected dropped children remain unclassified rather than malicious, so they do not corroborate the concerning runtime indicators.
- The file has medium prevalence with 3,579 sources and 7,655 submissions, which is inconsistent with a narrowly distributed new threat.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 1/74 engines reported a detection.
- Sixteen other tier-1 engines reported no detection.
- behaviour.hasMaliciousSandboxVerdict=false.
- droppedChildren.hasMaliciousChild=false across 10 inspected children.
- externalIntel.yaraify.ruleCount=0 and externalIntel.malwareBazaar.hit=false.
- GData detects Win32.Adware.WrappedOpera.A.
- The file.tags array includes revoked-cert.
- signing.trustedPublisher.matched=false and signing.verified=null for Alexis Sreckovic.
- contactedHosts identifies work.ink as suspicious with score 35.
- Runtime mappings include T1003, T1055, T1555.003, and T1562.001.
- Host-reputation inspection did not cover every observed network contact.
Avoid this copy and obtain a fresh Opera installer directly from the official vendor site. If it already executed, keep protection enabled and perform a full endpoint scan.

What this file does
Observed actions and their security significance
High concern: Accessed operating-system credential data, which can expose saved passwords.
High concern: Injected code into another process, a technique that can conceal execution.
High concern: Encrypted files or data, behaviour commonly associated with ransomware.
High concern: Searched files or settings where passwords and keys may be stored.
High concern: Accessed browser or password-store data that may contain saved logins.
High concern: Attempted to impair or bypass security controls.
High concern: Manipulated how the operating system loads code, which can redirect execution.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
EvidenceC:\Windows\system32\svchost.exe -k LocalSystemNetworkRestricted -pSandbox 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 accessed browser login databases (Chrome / Firefox / Edge / Opera) or a cryptocurrency wallet file. This is textbook infostealer behaviour — targeting saved passwords, cookies, or wallet keys.
EvidenceC:\Users\<USER>\AppData\Roaming\Opera Software\Opera Stable\Crash Reports\settings.datThe sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.
