Hindari Cyber Attack dengan Mengenali 5 Jenis Serangan Malware

Serangan
malware hampir setiap hari terjadi dan website dengan sistem keamanan yang
lemah selalu menjadi target utamanya. Karena tanda-tanda serangan yang kurang
jelas, maka banyak korban tidak menyadari bahwa mereka telah menjadi subjek
target.

Selain
merugikan untuk bisnis atau pemilik web, malware juga dapat memberi efek
negatif untuk pelanggan dan pengunjung web. Jumlah biaya yang harus dikeluarkan
untuk memulihkan web yang terinfeksi pun tidak sedikit. Bahkan tidak jarang
website dibiarkan rusak oleh pemiliknya karena mereka tidak memiliki keahlian
dan biaya untuk mengatasinya.

Sebagai
langkah awal untuk meminimalisir dampak yang ditimbulkan, maka Anda harus
memahami jenis-jenis serangan malware yang sering terjadi. Dengan demikian Anda
dapat segera mengambil tindakan ketika muncul indikasi serangan.

5
Jenis Serangan Malware

1.
Defacements

Defacement
merupakan jenis serangan yang paling sering terjadi dan cukup mudah dikenali.
Dalam serangan defacement, hacker akan mengubah tampilan web Anda. Hacker akan
mengganti konten situs web Anda dengan konten yang mereka inginkan. Jika hal
ini terjadi, maka website Anda akan mendapat reputasi yang buruk sehingga akan
mempengaruhi penjualan bisnis Anda.

2.
Backdoors

Backdoors
adalah kode tersembunyi yang disisipkan ke dalam situs Anda. Malware ini dapat
memberikan akses jarak jauh kepada hacker tanpa sepengetahuan pemilik web. Jika
Anda melihat website Anda memiliki halaman baru, konten yang berubah atau
menghilang, serta bandwidth yang sangat tinggi dari web host Anda, maka
serangan backdoors mungkin menjadi penyebab utamanya.

Redirects

Redirects
malware sering terjadi di internet
. Sesuai dengan namanya, malware
ini akan mengalihkan situs web Anda ke alamat web lain. Jenis malware ini mudah
diidentifikasi. Jika serangan ini dibiarkan, website Anda akan mengalami
penurunan traffic secara drastis.

4.
SEO Spam

SEO
mengacu pada berbagai tindakan untuk meningkatkan peringkat situs web dari
hasil mesin pencarian, seperti penggunaan keyword atau pun backlinks. Jika Anda
melihat link aneh, atau komentar yang mencurigakan muncul di situs web Anda,
maka SEO spam menjadi penyebabnya. Serangan ini membuat ratusan ribu file yang
diisi dengan link berbahaya dengan keyword yang tidak relevan ke halaman yang
terinfeksi. Jika web Anda terinfeksi, maka Google akan memasukkan situs web
Anda ke dalam daftar blacklist . Google juga akan menandai situs web yang
terinfeksi sehingga dapat mengurangi jumlah pengujung web.

5.
Malvertising

Serangan
malvertising dilakukan dengan cara menyuntikkan kode berbahaya ke dalam iklan.
Selain merugikan pemilik web, malvertising juga dapat merugikan pengunjung web
Anda. Pengunjung dapat terinfeksi ketika mereka membuka iklan, atau hanya
dengan mengunjungi website yang memasang iklan jahat.
