Issue 1: ImunifyAV "integer expression expected" errors
Problem:
- ImunifyAV 'list' output contains "None" in ERROR field
- Bash integer comparisons (-ge, -gt) fail when comparing "None"
- Error: "[: None: integer expression expected" at lines 857/859
Root Cause:
When polling scan status, fields extracted with awk can contain
literal "None" instead of numeric values, causing bash to fail
when using arithmetic comparison operators.
Solution:
Added regex validation before integer comparisons:
[[ "$var" =~ ^[0-9]+$ ]] && [ "$var" -ge value ]
Changes:
- Line 857: Validate created_time is numeric before -ge comparison
- Line 859: Validate completed_time is numeric before -gt comparison
This follows the pattern used in commit 179ae9d for input validation.
Issue 2: Maldet scanning 0 files (Duration: 0s)
Problem:
- Maldet event log shows: "scan returned empty file list"
- Summary shows: "Duration: 0s" and "Found: 0"
- Maldet completed instantly without scanning anything
Root Cause:
Maldet by default only scans files modified in last 1 day (uses -mtime -1).
When scanning /, most system files are older, so Maldet finds nothing
to scan and exits immediately.
Evidence from /usr/local/maldetect/logs/event_log:
"scan returned empty file list; check that path exists,
contains files in days range or files in scope of configuration"
Solution:
Added -a flag to scan ALL files regardless of modification time:
maldet -b -a -f "$TEMP_PATHLIST"
The -a flag disables the default 1-day file age filter, ensuring
all files in the specified paths are scanned for malware.
Note: ImunifyAV Speed is Normal
User questioned why ImunifyAV scans 4611 files in 55s. This is expected:
- rapid_scan: true (optimized scanning)
- Only scans file types that can contain malware (PHP, JS, etc.)
- Skips binaries, images, videos, system files
- This is by design for performance and is working correctly
Status: ✅ Both issues resolved
