Amadey

Amadey häkkimistööriist on botnettide koostaja, mille on välja töötanud tundmatud pahatahtlikud ohustajad ja mida müüakse erinevates häkkimisfoorumites. See ilmus esmakordselt 2019. aasta alguses. Seda ohtu saab kasutada ka esimese etapi kasuliku koormana, mis võib hostile tuua täiendavat pahavara. Algselt maksis Amadey häkkimistööriist ligikaudu 500 dollarit. See oht saavutas mõningase haarde ja näib olevat hästi müüdud, kuna pahavarauurijad on märganud, et Amadey tööriista kasutatakse paljudes erinevates kampaaniates kogu maailmas. Isegi kurikuulus TA505 häkkimisgrupp sai Amadey ohule käed külge.

Jaotustaktika

Amadey on teatud tüüpi pahavara, mis sihib peamiselt Windowsi-põhiseid süsteeme. Tavaliselt siseneb see sihtsüsteemi mitmel viisil, sealhulgas:

1. Meilimanused : Amadey'd võidakse levitada rämpsposti teel, mis sisaldab pahatahtlikke manuseid, nagu nakatunud Microsoft Office'i dokumendid (nt Wordi või Exceli failid), PDF-failid või ZIP-arhiivid. Kui saaja avab manuse, saab pahavara käivitada.
2. Pahatahtlikud veebisaidid : Amadeyt saab edastada ohustatud või pahatahtlike veebisaitide kaudu. See võib juhtuda, kui külastate ohtu sattunud veebisaiti või klõpsate pahatahtlikul lingil, mis käivitab automaatse allalaadimise, mille tulemusena installitakse teie süsteemi ilma teie teadmata pahatahtlik programm.
3. Exploit Kits : Exploit komplektid on tööriistakomplektid, mida küberkurjategijad kasutavad tarkvara haavatavuste ärakasutamiseks. Amadeyt võidakse levitada nii, mis kasutab ära parandamata tarkvara haavatavusi, et toimetada pahavara sihtsüsteemi.

Töötab vaikselt

Amadey operaatorid saavad nakatunud süsteemide käsutamiseks oma veebibrauseri kaudu administraatoriõigused ja kaugjuurdepääsu. Seda kõike tehakse aga vaikselt ja kannatanu kasutaja silme alt väljas. On tõenäoline, et ohvrid ei pruugi isegi aru saada, et pahavara on nende süsteemi kaaperdanud ja see on nüüd botneti osa.

Püsivus

Kui Amadey robotivõrgu koostaja on süsteemi imbunud, saab ta kontrollida, kas seal on mõni levinuim pahavaratõrjevahend. Amadey häkkimistööriist suudab Windowsi registrit muutes püsivaks muuta, tagades sellega, et oht käivitub iga kord, kui süsteem taaskäivitatakse.

Võimalused

Sellel häkkimistööriistal on mõnevõrra piiratud võimaluste loend. Amadey robotivõrgu koostaja saab koguda teavet nakatunud hosti kohta, sealhulgas:

• Operatsioonisüsteem.
• Kasutajanimi.
• Võrgu konfiguratsioon.
• Riistvara.

Lisaks sellele, et see oht on võimalik kaaperdada arvuti ja lisada see robotvõrku, mida kasutataks potentsiaalselt DDoS-i (Distributed-Denial-of-Service) rünnakute läbiviimiseks, saab seda ohtu kasutada ka esimese etapi kasuliku koormana, mis on ründajatele tagauks, et nakatada host täiendava ja potentsiaalselt ohtlikuma pahavaraga.

Keegi meist ei saa tänapäeval lubada küberjulgeolekust tähelepanuta jätta. Veenduge, et laadite alla ja installite seadusliku viirusetõrjetarkvara, mis hoiab teie süsteemi turvalisena.

Kuidas vältida Amadey Boti

Amadey pahavara ja sarnaste ohtude vältimiseks kaaluge järgmiste ennetusmeetmete rakendamist.

1. Tarkvara värskendamine : värskendage regulaarselt oma operatsioonisüsteemi, veebibrausereid ja muid tarkvararakendusi.
2. Olge meilimanustega ettevaatlik : kui saate ootamatu manuse, kontrollige enne selle avamist saatjaga mõne muu sidekanali kaudu selle autentsust.
3. Olge andmepüügikatsete suhtes ettevaatlik : vältige klõpsamist e-kirjades või sõnumites olevatel linkidel, mis tunduvad kahtlased või pärinevad ebausaldusväärsetest allikatest.
4. Kasutage usaldusväärset turbetarkvara : installige oma süsteemi mainekad viirusetõrjetooted ja pahavaratõrjetarkvara ning hoidke seda ajakohasena.
5. Regulaarne andmete varundamine : tehke oma olulistest failidest ja andmetest regulaarselt varukoopiaid eraldi salvestusseadmetes või pilves. Pahavara nakatumise või muude vahejuhtumite korral tagab hiljutiste varukoopiate olemasolu oma andmete taastamise ja võimaliku kahju minimeerimise.
6. Kasutage turvalise sirvimise harjumusi : vältige kahtlaste või ebausaldusväärsete veebisaitide külastamist. Olge reklaamidel või linkidel klõpsamisel ettevaatlik, kuna need võivad teid suunata pahavara levitavatele pahatahtlikele veebisaitidele.
