Rostelecom yakaita ongororo yeDDoS kurwiswa kwakaitwa pachikamu cheRussia cheInternet muna 2018. Sezvinoratidzwa neshumo, mu2018 pakanga paine kuwedzera kwakanyanya kwete chete muhuwandu hwekurwiswa kweDDoS, asiwo musimba ravo. Kutarisisa kwevapambi kazhinji kazhinji kwakatendeukira kumaseva emutambo.
Huwandu hwese hwekurwiswa kweDDoS muna 2018 hwakawedzera ne95% zvichienzaniswa negore rapfuura. Nhamba huru yekurwisa yakanyorwa munaNovember naDecember. Mazhinji e-commerce makambani anogamuchira chikamu chakakosha chepurofiti yavo pakupera kwegore, i.e. pazororo reGore Idzva uye mavhiki anoatangira. Makwikwi akanyanya kunyanya panguva iyi. Mukuwedzera, panguva yezororo kune peak mubasa revashandisi mumitambo yepaIndaneti.
Kurwiswa kwakareba kwakanyorwa neRostelecom muna 2017 kwakaitika munaAugust uye kwakatora maawa 263 (anenge mazuva gumi nerimwe). Muna 11, kurwiswa kwakanyorwa munaKurume uye kwakagara maawa makumi maviri nemasere (mazuva gumi nematanhatu nemaawa gumi nematanhatu) kwakasvika mazinga erekodhi.
Gore rapfuura rakaona kuwedzera kwakanyanya kwesimba rekurwiswa kweDDoS. Kana muna 2017 nhamba iyi haina kudarika 54 Gbit / s, zvino muna 2018 kurwisa kwakanyanya kwakaitwa nekumhanya kwe450 Gbit / s. Uku kwanga kusiri kushanduka kwega: kaviri chete pagore iyo nhamba iyi yakadonha zvakanyanya pasi pe50 Gbit/s - muna Chikumi naNyamavhuvhu.
Ndiani anorwiswa kakawanda?
Nhamba kubva muna 2018 inosimbisa kuti kutyisidzira kweDDoS kunonyanya kukosha kumaindasitiri ane maitiro akakosha ebhizinesi anoenderana nekuwanikwa kwemasevhisi epamhepo uye maapplication - kunyanya chikamu chemitambo uye e-commerce.
Mugove wekurwiswa pamaseva emutambo waiva 64%. Maererano nevanoongorora, mufananidzo wacho haungashanduki mumakore anotevera, uye nekuvandudzwa kwe-e-sports, tinogona kutarisira kuwedzera kuwedzera kwenhamba yekurwiswa kwemhizha. E-commerce mabhizinesi anogaro "kubata" nzvimbo yechipiri (16%). Kuenzaniswa ne2017, chikamu chekurwiswa kweDDoS panharembozha chakawedzera kubva pa5% kusvika ku10%, nepo chikamu chezvikoro zvedzidzo, pane zvinopesana, chakaderera - kubva pa10% kusvika 1%.
Zvinonyatsofanotaurwa kuti maererano neavhareji yenhamba yekurwiswa pamutengi, chikamu chemitambo uye e-commerce chinotora zvikamu zvakakosha - 45% uye 19%, zvichiteerana. Zvimwe zvisingatarisirwi kuwedzera kukuru kwekurwiswa kwemabhangi uye masystem ekubhadhara. Zvisinei, izvi zvinonyanya kuitika nekuda kwekunyarara kwazvo 2017 mushure memushandirapamwe wekurwisana neRussia banking sector pakupera kwe 2016. Muna 2018, zvinhu zvose zvakadzokera kune zvakajairika.
Kurwisa Nzira
Iyo inonyanya kufarirwa nzira yeDDoS ndeye UDP mafashama - ingangoita 38% yekurwiswa kwese kunoitwa uchishandisa nzira iyi. Izvi zvinoteverwa neSYN mafashamo (20,2%) uye yakaganhurwa zvakaenzana neyakakamurwa packet kurwiswa uye DNS amplification - 10,5% uye 10,1%, zvichiteerana.
Panguva imwecheteyo, kuenzanisa kwehuwandu hwe2017 uye 2018. inoratidza kuti chikamu cheSYN mafashamo ekurwisa chakapetwa kaviri. Isu tinofungidzira kuti izvi zvinokonzerwa nekureruka kwavo uye mutengo wakaderera - kurwiswa kwakadaro hakudi kuvepo kwebhotnet (kureva, mari yekugadzira / yekurenda / kuitenga).
Huwandu hwekurwiswa uchishandisa amplifiers hwawedzera. Pakuronga DDoS nekusimudzira, vanorwisa vanotumira zvikumbiro nekero yekunyepedzera kune maseva, ayo anopindura munhu anenge arwiswa nemapaketi akawedzera. Iyi nzira yekurwiswa kweDDoS inogona kusvika kune imwe nhanho uye yakapararira zvakanyanya munguva pfupi iri kutevera, sezvo isingadewo mutengo wekuronga kana kutenga botnet. Kune rumwe rutivi, nekuvandudzwa kweInternet yeZvinhu uye kuwedzera kwehuwandu hunozivikanwa husina simba mumidziyo yeIoT, tinogona kutarisira kubuda kwemabhoti matsva ane simba, uye naizvozvo, kuderedzwa kwemari yebasa rekuronga DDoS kurwisa.
