Mi az a Vishing?<\/h2>\n

A Vishing olyan kiberbiztons\u00e1gi t\u00e1mad\u00e1s, amelynek sor\u00e1n egy rosszindulat\u00fa szervezet telefonon veszi fel a kapcsolatot az \u00e1ldozattal, \u00e9s megpr\u00f3b\u00e1lja elnyerni az \u00e1ldozat bizalm\u00e1t social engineering m\u00f3dszerekkel annak \u00e9rdek\u00e9ben, hogy bizalmas adatokat szerezzen, p\u00e9nzeszk\u00f6z\u00f6ket szerezzen, vagy m\u00e1s m\u00f3don k\u00e1rt okozzon az egy\u00e9nnek.<\/p>\n

Ez l\u00e9nyeg\u00e9ben egyfajta adathal\u00e1sz-t\u00e1mad\u00e1s, amelyet hangm\u00e9di\u00e1n kereszt\u00fcl hajtanak v\u00e9gre, ez\u00e9rt is nevezik vishing-t\u00e1mad\u00e1snak.<\/p>\n

Vishing t\u00e1mad\u00e1si mechanizmus<\/h2>\n

A Vishing \u00e1ltal\u00e1ban s\u00fcrg\u0151s vagy zavar\u00f3 telefonh\u00edv\u00e1s form\u00e1j\u00e1ban t\u00f6rt\u00e9nik. A h\u00edv\u00f3 p\u00e9ld\u00e1ul azt \u00e1ll\u00edthatja, hogy az \u00e1ldozat sz\u00e1ml\u00e1j\u00e1t felt\u00f6rt\u00e9k, \u00e9s hogy a szem\u00e9lyazonoss\u00e1g\u00e1nak meger\u0151s\u00edt\u00e9s\u00e9hez vagy a sz\u00e1mla \u00fajb\u00f3li megnyit\u00e1s\u00e1hoz PIN-k\u00f3dra van sz\u00fcks\u00e9ge.<\/p>\n

El\u0151fordulhat az is, hogy azt \u00e1ll\u00edtj\u00e1k, hogy egy korm\u00e1nyhivatal, p\u00e9ld\u00e1ul az Internal Revenue Service (IRS) vagy a Social Security Administration nev\u00e9ben telefon\u00e1lnak. Ak\u00e1r azt is \u00e1ll\u00edthatj\u00e1k, hogy az \u00e1ldozatnak p\u00e9nztartoz\u00e1sa van, vagy hogy megnyert egy versenyt.<\/p>\n

Ezek mind a \"vishing\" esetei (ahogyan azt m\u00e1r eml\u00edtett\u00fck, a \"hang\" \u00e9s az \"adathal\u00e1szat\" kever\u00e9ke, amely a telefonos \u00e1tver\u00e9st jelzi). Az adathal\u00e1szat kifejez\u00e9s a kiberb\u0171n\u00f6z\u0151k minden olyan t\u00f6rekv\u00e9s\u00e9t jellemzi, amellyel arra pr\u00f3b\u00e1lj\u00e1k r\u00e1venni az embereket, hogy p\u00e9nzt, szem\u00e9lyes adatokat vagy titkos inform\u00e1ci\u00f3kat adjanak \u00e1t.

A Vishing olyan kiberb\u0171ncselekm\u00e9ny, amelynek sor\u00e1n a b\u0171n\u00f6z\u0151k az \u00e1ldozatok telefonj\u00e1t haszn\u00e1lj\u00e1k fel arra, hogy olyan inform\u00e1ci\u00f3kat szerezzenek, amelyek \u00e1rthatnak az illet\u0151nek, vagy valamilyen m\u00f3don az elk\u00f6vet\u0151nek kedveznek.<\/p>\n

A kibercsal\u00f3k kifinomult social engineering technik\u00e1kat alkalmaznak, hogy meggy\u0151zz\u00e9k az \u00e1ldozatokat szem\u00e9lyes adatok megad\u00e1s\u00e1r\u00f3l, s\u0151t, ak\u00e1r banksz\u00e1ml\u00e1khoz vagy \u00fczleti titkokhoz val\u00f3 hozz\u00e1f\u00e9r\u00e9sr\u0151l is. A smishinghez \u00e9s az adathal\u00e1szathoz hasonl\u00f3an a vishing is arra \u00f6sszpontos\u00edt, hogy meggy\u0151zze az \u00e1ldozatokat arr\u00f3l, hogy a h\u00edv\u00f3 k\u00f6vetel\u00e9seinek teljes\u00edt\u00e9se a megfelel\u0151 v\u00e1lasz.

E taktika sikere a hat\u00e9kony social engineeringt\u0151l f\u00fcgg, azaz az ember pszichol\u00f3gi\u00e1j\u00e1nak kihaszn\u00e1l\u00e1s\u00e1t\u00f3l, hogy meggy\u0151z\u0151 hat\u00e1st \u00e9rjen el. A Vishing elk\u00f6vet\u0151i fenyeget\u00e9sekkel vagy pozit\u00edv meggy\u0151z\u00e9ssel \u00e9rik el, hogy az \u00e1ldozatok \u00fagy \u00e9rezz\u00e9k, meg kell adniuk a k\u00e9rt inform\u00e1ci\u00f3kat. Az \u00e1ldozatok fenyeget\u0151 hang\u00fczeneteket is kaphatnak, amelyekben k\u00f6zlik vel\u00fck, hogy b\u00fcntet\u0151elj\u00e1r\u00e1s vagy banksz\u00e1ml\u00e1juk befagyaszt\u00e1sa fenyeget, ha nem h\u00edvj\u00e1k vissza \u0151ket megfelel\u0151en.<\/p>\n

Hogyan m\u0171k\u00f6dik a vishing?<\/h2>\n

Az adathal\u00e1sz t\u00e1mad\u00f3k gyakran haszn\u00e1lj\u00e1k a h\u00edv\u00f3sz\u00e1m hamis\u00edt\u00e1s\u00e1t, hogy az \u00e1ldozatokkal elhitess\u00e9k, hogy a telefonh\u00edv\u00e1s egy megb\u00edzhat\u00f3 v\u00e1llalkoz\u00e1st\u00f3l vagy egy helyi k\u00f6rzetsz\u00e1mt\u00f3l \u00e9rkezik.<\/p>\n

Gyakran megb\u00edzhat\u00f3 szervezetk\u00e9nt l\u00e9pnek fel, hogy becsapj\u00e1k az \u00e1ldozatokat, \u00e9s r\u00e1vegy\u00e9k \u0151ket az adataik megoszt\u00e1s\u00e1ra.

Ezek a csal\u00f3k a s\u00fcrg\u0151ss\u00e9g \u00e9rzet\u00e9t keltik, amikor a kiszemelt \u00e1ldozat felveszi a telefont, hogy kihaszn\u00e1lj\u00e1k az \u00e9rz\u00e9seiket, \u00e9s arra k\u00e9nyszer\u00edts\u00e9k \u0151ket, hogy v\u00e1laszoljanak a k\u00f6vetel\u00e9sekre.<\/p>\n

A Vishing sokf\u00e9le form\u00e1t \u00f6lthet, de a c\u00e9l mindig ugyanaz: becsapni az \u00e1ldozatot, hogy szem\u00e9lyes adatokat adjon ki, ak\u00e1r p\u00e9nzbeli haszonszerz\u00e9s c\u00e9lj\u00e1b\u00f3l, ak\u00e1r m\u00e1s b\u0171ncselekm\u00e9nyek, p\u00e9ld\u00e1ul szem\u00e9lyazonoss\u00e1g-lop\u00e1s elk\u00f6vet\u00e9se \u00e9rdek\u00e9ben.<\/p>\n

Ki veszi fel a telefont, ha a szervezet \u00e1ltal\u00e1nos sz\u00e1ma cs\u00f6r\u00f6g? K\u00f6nnyen el\u0151fordulhat, hogy a telefon rossz alkalmazott kez\u00e9be ker\u00fcl?<\/p>\n

Sz\u00fcks\u00e9g eset\u00e9n hasznos lehet egy k\u00fcl\u00f6n recepci\u00f3st alkalmazni, aki kisz\u0171ri a rosszat a j\u00f3b\u00f3l, \u00e9s biztos\u00edtja, hogy minden alkalmazott ellen\u0151rizze, ki h\u00edv, amikor tov\u00e1bbadja valaki m\u00e1snak.<\/p>\n

5. Biztos\u00edtsa, hogy minden eszk\u00f6z t\u00f6bbfaktoros hiteles\u00edt\u00e9ssel rendelkezzen.<\/strong><\/p>\n

A nagy biztons\u00e1g\u00fa jelszavak haszn\u00e1lata mind sz\u00e9p \u00e9s j\u00f3, de a t\u00f6bbfaktoros hiteles\u00edt\u00e9s olyan extra biztons\u00e1gi r\u00e9tegeket biztos\u00edt, amelyek biztos\u00edtj\u00e1k, hogy a fi\u00f3kj\u00e1t egyetlen jelsz\u00f3val sem lehet kompromitt\u00e1lni.<\/p>\n

A Google bejelentette, hogy 2021-re 150 milli\u00f3 felhaszn\u00e1l\u00f3 sz\u00e1m\u00e1ra lesz k\u00f6telez\u0151 a t\u00f6bbfaktoros hiteles\u00edt\u00e9s, hogy a fenyeget\u00e9sekkel szemben fokozott biztons\u00e1got ny\u00fajtson, \u00e9s \u00edgy 50%-vel cs\u00f6kkentse a kompromitt\u00e1lt fi\u00f3kok sz\u00e1m\u00e1t.<\/p>\n

Lehet, hogy az \u00d6n szervezete sz\u00e1m\u00e1ra nem jelent komoly aggodalmat a Vishing, pedig kellene, hogy jelentsen. Nem sz\u00e1m\u00edt, hogy mennyire okos vagy \u00fcgyes a v\u00e1llalata \u00e9s a koll\u00e9g\u00e1i, a social engineering taktik\u00e1k el\u00e9g er\u0151sek ahhoz, hogy b\u00e1rkit v\u00e1ratlanul \u00e9rjenek.<\/p>\n

Most, hogy m\u00e1r tud a vishingr\u0151l, fontos, hogy megossza ezt az inform\u00e1ci\u00f3t az alkalmazottaival.<\/p>\n

Tudassa vel\u00fck, hogy a h\u00edv\u00f3 f\u00e9l kik\u00e9rdez\u00e9se \u00e9s az inform\u00e1ci\u00f3k hivatalos csatorn\u00e1kon kereszt\u00fcl t\u00f6rt\u00e9n\u0151 ellen\u0151rz\u00e9se jelentheti a k\u00fcl\u00f6nbs\u00e9get a biztons\u00e1gos adatok \u00e9s a kibernetikai incidens vagy az adats\u00e9rt\u00e9s kock\u00e1zata k\u00f6z\u00f6tt.<\/p>\n
