Bu muhtemelen bu listedeki en yayg\u0131n siber sald\u0131r\u0131 t\u00fcr\u00fcd\u00fcr. Burada bilgisayar korsan\u0131, kendini bir banka m\u00fcd\u00fcr\u00fc olarak tan\u0131t\u0131r ve hedeflenen ki\u015finin hesab\u0131nda baz\u0131 hileli i\u015flemler oldu\u011funu iddia eder. Bilgisayar korsan\u0131 ayr\u0131ca bankan\u0131n bir \u00e7ek ald\u0131\u011f\u0131n\u0131 ve bunu hedeflenen ki\u015finin hesab\u0131na yat\u0131rmak istedi\u011fini de iddia edebilir.<\/p>\n\n\n\n

4. Teknik Destek<\/h3>\n\n\n\n

Bu \u00f6rnekte, siber su\u00e7lular Microsoft gibi \u015firketlerin teknik destek temsilcileri olduklar\u0131n\u0131 iddia eder. Hedeflenen ki\u015finin cihaz\u0131nda bulunan vir\u00fcsler hakk\u0131nda derinlemesine konu\u015furlar. Ard\u0131ndan, hedeflenen ki\u015fiden e-posta yoluyla g\u00f6nderecekleri belirli bir antivir\u00fcs yaz\u0131l\u0131m\u0131n\u0131 y\u00fcklemesini isterler.

Bireysel Olarak Vishing Sald\u0131r\u0131lar\u0131n\u0131 \u00d6nlemek i\u00e7in 3 \u0130pucu<\/h2>\n\n\n\n

1. Konu\u015fmalar\u0131n\u0131z\u0131n Fark\u0131nda Olun<\/h3>\n\n\n\n

\u015e\u00fcpheli bir ki\u015fi sizi ararsa her zaman fark\u0131ndal\u0131\u011f\u0131n\u0131z\u0131 koruyun. Bilgisayar korsanlar\u0131n\u0131n telefonda neredeyse herkes gibi davranabilece\u011fini unutmay\u0131n. Aramaya devam etmeden \u00f6nce her zaman ilgili kurulu\u015fla iki kez kontrol edin.<\/p>\n\n\n\n

2. Hassas Bilgileri A\u00e7\u0131klamaktan Ka\u00e7\u0131n\u0131n<\/h3>\n\n\n\n

Telefonda kendinizle ilgili herhangi bir bilgiyi a\u00e7\u0131klamaktan ka\u00e7\u0131n\u0131n. Bu ipucu sadece banka hesap bilgileriniz ve PIN kodlar\u0131n\u0131zla ilgili de\u011fildir. Asl\u0131nda, telefonda herhangi bir bilgi t\u00fcr\u00fcn\u00fc a\u00e7\u0131klamamal\u0131s\u0131n\u0131z. Buna ev adresiniz ve kendinizle ilgili di\u011fer ki\u015fisel bilgiler de dahildir. Hi\u00e7bir yasal kurulu\u015fun telefonla aray\u0131p ki\u015fisel bilgilerinizi istemeyece\u011fini unutmay\u0131n.<\/p>\n\n\n\n

3. Yaln\u0131zca G\u00fcvenilir Arayanlardan Gelen \u00c7a\u011fr\u0131lar\u0131 Kabul Edin<\/h3>\n\n\n\n

\u015e\u00fcpheli numaralardan gelen aramalar\u0131 yan\u0131tlamaktan ka\u00e7\u0131n\u0131n. Bunun yerine, arayanlar\u0131n sesli mesaj b\u0131rakmas\u0131na izin verin. Konuyla ilgili oldu\u011funu d\u00fc\u015f\u00fcn\u00fcyorsan\u0131z daha sonra yan\u0131t verebilirsiniz. Siber sald\u0131rganlar asla sesli mesaj b\u0131rakmazlar. \u0130stenmeyen numaralardan arama almamak i\u00e7in telefon numaran\u0131z\u0131 Aramay\u0131n kay\u0131t defterine bile kaydedebilirsiniz. <\/p>\n\n\n\n

  • Ki\u015fisel bilgilerinizi, i\u015f yerinizi veya ev adresinizi telefonda vermeyin veya teyit etmeyin.<\/li>
  • Bilinmeyen numaralardan gelen telefonlara cevap vermeyin. Aramay\u0131 sesli mesaja b\u0131rak\u0131n ve yan\u0131t vermeden \u00f6nce mesaj\u0131n me\u015fruiyetini de\u011ferlendirin.<\/li>
  • Anormallikleri veya garip arka plan g\u00fcr\u00fclt\u00fcs\u00fcn\u00fc tespit etmek i\u00e7in arayan\u0131n sesini dikkatlice dinleyin.<\/li>
  • Taleplere yan\u0131t vermeden \u00f6nce duraklay\u0131n-\u00f6zellikle de talepler acilse. Arayan ki\u015fi h\u0131zl\u0131 hareket etme sorumlulu\u011funuzu istismar ediyor olabilir.<\/li>
  • Sorular sorun. Arayan ki\u015fi bilgi talep ediyor veya bir \u00f6d\u00fcl teklif ediyorsa, kim olduklar\u0131n\u0131 do\u011frulamak i\u00e7in adlar\u0131na ve \u015firket telefon numaralar\u0131na ihtiyac\u0131n\u0131z oldu\u011funu s\u00f6yleyin. Bu bilgileri vermeyi reddederlerse telefonu kapat\u0131n. Verirlerse, kar\u015f\u0131l\u0131\u011f\u0131nda bilgilerinizi vermeden \u00f6nce yasal oldu\u011fundan emin olun.<\/li>
  • Hassas bilgiler i\u00e7eren i\u015f aramalar\u0131 i\u00e7in bir kimlik do\u011frulama s\u00fcreci uygulay\u0131n. Arayan ki\u015fi bir i\u015f arkada\u015f\u0131n\u0131z\u0131 taklit ediyor ancak bir g\u00fcvenlik sorusuna yan\u0131t veremiyorsa, bu bir vishing giri\u015fimi olabilir.<\/li>
  • Telefon numaran\u0131z\u0131 isteyen e-posta\u2019lara veya sosyal medya mesajlar\u0131na yan\u0131t vermeyin. Bu taktik genellikle hedefli bir vishing sald\u0131r\u0131s\u0131n\u0131n ilk ad\u0131m\u0131d\u0131r. Bunun yerine, bu e-posta\u2019lar\u0131 ve mesajlar\u0131 BT ekibinize bildirin.<\/li>
  • Telefonunuzda spam aramalar\u0131 engelleyen veya filtreleyen koruma \u00f6zelliklerini ke\u015ffedin ve etkinle\u015ftirin.<\/li><\/ul>\n\n\n\n
