Yes—CVE-2025-8088 remains a live concern for small and midsize businesses (SMBs), but “hit hardest” is not a measured finding. Google Threat Intelligence Group (GTIG) documented exploitation before RARLAB released a fix and campaigns continuing through December 2025 and January 2026. SMBs may face elevated exposure when WinRAR installations are overlooked, uninventoried or used routinely to open partner files.
What CVE-2025-8088 does
CVE-2025-8088 is a high-severity path-traversal vulnerability in Windows WinRAR-related components. An attacker can place a malicious file in an archive’s Alternate Data Stream (ADS), disguise it with a harmless-looking document and use a crafted path to write outside the folder a user selected for extraction.
GTIG described attacks that wrote payloads into a Windows Startup folder. The file could then run when the victim next logged in. NIST’s National Vulnerability Database describes the issue as path traversal that can enable arbitrary code execution through a crafted archive.

RARLAB released WinRAR 7.13 on July 30, 2025. Its release note says the flaw allowed specially crafted archives to bypass the user-selected extraction path and write to unintended locations.

| Component or platform | Status under RARLAB’s 7.13 release information |
|---|---|
| WinRAR for Windows | Affected; update to 7.13 or later |
| RAR and UnRAR for Windows | Affected; update to versions covered by the 7.13 release |

| Portable UnRAR for Windows | Affected; update to the fixed release |
| Linux/Unix builds | RARLAB says these are not affected |
| RAR for Android | RARLAB says this is not affected |
Updating Windows itself does not fix an old WinRAR installation. Check every copy, including portable utilities and bundled or rarely used components.
Why exploitation continued after the fix
GTIG observed exploitation as early as July 18, 2025—12 days before the vendor’s release—and reported continued activity in its January 27, 2026 report. The later campaigns delivered commodity remote-access trojans and information stealers during December 2025 and January 2026.

CISA added CVE-2025-8088 to its Known Exploited Vulnerabilities catalog on August 12, 2025, citing evidence of active exploitation. CISA advises organizations to prioritize timely remediation of vulnerabilities in that catalog.
These reports establish ongoing exploitation, not the number of unpatched computers or the number of successful compromises. A patch being available does not mean every installation has received it, especially when the software is treated as an occasional utility rather than managed business software.
Rank #3
Who has been observed exploiting it?
GTIG reported several campaign examples rather than a single attacker profile:
- Russia-nexus activity targeting Ukrainian military and government entities.
- A PRC-based actor delivering POISONIVY.
- Financially motivated campaigns using travel and hospitality lures, including XWorm and AsyncRAT.
- Activity aimed at Indonesian entities and Brazilian users.
Those observations show that both espionage-linked and financially motivated actors used the flaw. They do not mean every WinRAR user is being targeted equally.

Why SMBs may have elevated exposure
Dark Reading quoted Douglas McKee, Rapid7’s director of vulnerability intelligence, describing SMBs and professionals who routinely exchange compressed files as particularly exposed. The operational reasons are straightforward:
The Tool Desk
Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →- WinRAR can remain installed for years without appearing in a current software inventory.
- Small IT teams may lack automated patch verification for desktop utilities.
- Employees in administrative, technical and operational roles often need to open archives from customers, suppliers or colleagues.
- A trusted workflow makes a decoy document inside an archive more likely to be opened.
McKee characterized WinRAR as software that can “sit quietly on systems for years, rarely used, rarely updated, and rarely thought of as part of the attack surface.” He also noted that archive-dependent jobs require trust in shared files. This is an expert assessment of exposure patterns, not a comparative victim count: the available reporting does not establish that SMBs have more infections or a higher incident rate than large enterprises.

What an SMB should do now
- Inventory installations. Check managed software records, endpoint-management consoles and representative Windows devices. Include portable copies and machines used outside the main office.
- Verify the version and components. On each Windows system, open WinRAR and use Help > About WinRAR to record the version. Confirm that related RAR, UnRAR, UnRAR.dll and portable components are also covered.
- Install the vendor fix. Download the current Windows release from RARLAB and update to WinRAR 7.13 or later. Apply the same review to standalone or bundled components.
- Confirm deployment. Recheck the version after installation and record the device, user, date and result. Escalate systems that cannot be updated or are no longer supported.
- Reduce archive risk while remediation is underway. Treat unexpected RAR files, especially those arriving by email or shared services, as untrusted. Verify the sender through a separate channel and avoid opening unsolicited archives on ordinary user workstations.
- Investigate suspicious systems. Review Startup-folder changes, unexpected files created during archive extraction and endpoint alerts. If compromise is suspected, isolate the device and follow the organization’s incident-response process.
Managed versus unmanaged exposure
| Condition | Typical security position |
|---|---|
| Managed installation | Version is inventoried, updates are deployed centrally and exceptions are tracked. |
| Unmanaged installation | The utility may be missed by scans, remain unpatched and be used to open externally supplied archives without additional review. |
The practical difference is not company size alone. An SMB with accurate inventory and enforced updates can be better positioned than a larger organization with unmanaged desktop software.
Bottom line on the “hit hardest” claim
CVE-2025-8088 is a real, actively exploited Windows WinRAR vulnerability. The fix has been available since July 30, 2025, yet GTIG saw exploitation months later. SMBs that depend on shared archives and lack disciplined software inventory may have elevated exposure, but current public evidence does not quantify an SMB-versus-enterprise gap. The defensible response is to find every affected Windows component, update it to 7.13 or later and treat unexpected archives as potentially malicious.
