🟦 6. Scan Code Manually Using Notepad++

Wakati mwingine malware haionekani kama virus lakini ni malicious PHP or JS code.

Search for Dangerous Patterns

Open Notepad++

Press CTRL + SHIFT + F

Search for strings:

eval(
base64_
gzinflate(
shell_exec
system(
preg_replace('/.*/e'


Hii itakuonyesha files zenye code zilizofichwa.

🟦 7. Use VS Code + Security Extensions

Extensions kama:

PHP Security Analysis

SonarLint

CodeQL Scan (GitHub)

Huonyesha:

Suspicious functions

Encoded strings

Vulnerable code

🟦 8. Scan ZIP Files Before Uploading

Usi-upload backup au plugin bila kuiscan.

Right-click ZIP file → Scan with Microsoft Defender

🟦 9. Check Image Files (Hidden Malware)

Hackers mara nyingi huingiza PHP code ndani ya image files.

Check if an image contains PHP

Open image using Notepad → ukiona code kama:

<?php eval(base64_decode("...")); ?>


Hiyo image ni malware shell disguised.

🟦 10. Scan Using Python Script (Optional for Advanced Users)

Unaweza kuscan strings za hatari automatically.

import os

danger = ["eval(", "base64_decode", "gzinflate", "shell_exec"]

for root, dirs, files in os.walk("."):
for f in files:
if f.endswith(".php"):
path = os.path.join(root, f)
with open(path, "r", errors="ignore") as file:
content = file.read()
for d in danger:
if d in content:
print(f"[!] Suspicious: {path} contains {d}")

🧩 Hitimisho

Kabla ya kurudisha files kwenye server, ni muhimu kuiscan locally kwenye Windows ili kuhakikisha:

Hakuna malware

Hakuna backdoor

Hakuna injected code

Hakuna suspicious scripts

Scanning local backups ni moja ya hatua muhimu zaidi za cybersecurity.
