2020 yog xyoo sau tseg rau kev them nyiaj ransomware ($ 692 lab), thiab 2021 tej zaum yuav siab dua thaum tag nrho cov ntaub ntawv nyob hauv, Chainalysis tsis ntev los no qhia. Ntxiv mus, nrog rau kev tawm tsam ntawm Ukraine-Russia tsov rog, ransomware siv los ua cov cuab yeej geopolitical - tsis yog nyiaj rub - yuav tsum loj hlob ib yam nkaus.
Tab sis, txoj cai tshiab hauv Teb Chaws Asmeskas tuaj yeem cuam tshuam qhov kev tawm tsam kev tawm tsam. Tebchaws Asmeskas Thawj Tswj Hwm Joe Biden tsis ntev los no kos npe Raws li txoj cai lij choj Strengthening American Cybersecurity Act, lossis Peters daim nqi, xav kom cov tuam txhab tsim kho vaj tse yuav tsum tshaj tawm rau tsoomfwv cov kev tawm tsam cyber-attacks hauv 72 teev thiab hauv 24 teev yog tias lawv them nyiaj ransomware.
Vim li cas qhov no tseem ceeb? Kev tshuaj xyuas Blockchain tau ua pov thawj tias muaj txiaj ntsig zoo hauv kev cuam tshuam ransomware tes hauj lwm, raws li pom nyob rau hauv cov ntaub ntawv Colonial Pipeline xyoo tas los, qhov chaw Department of Justice muaj peev xwm. rov qab $ 2.3 lab ntawm tag nrho cov tuam txhab pipeline them rau lub nplhaib ransomware.
Tab sis, txhawm rau tswj hwm qhov zoo li no, xav tau cov ntaub ntawv ntau ntxiv thiab nws yuav tsum tau muab rau lub sijhawm ntau dua, tshwj xeeb yog txiv neej 'crypto chaw nyob, yuav luag txhua qhov kev tawm tsam ransomware. koom nrog blockchain-based cryptocurrencies, feem ntau Bitcoin (BTC).
Qhov no yog qhov uas txoj cai tshiab yuav tsum pab vim tias, txog tam sim no, cov neeg raug tsim txom ransomware tsis tshua qhia txog kev quab yuam rau tsoomfwv lossis lwm tus.
"Nws yuav pab tau zoo," Roman Bieda, tus thawj coj ntawm kev tshawb nrhiav kev dag ntxias ntawm Coinfirm, hais rau Cointelegraph. "Lub peev xwm tam sim ntawd 'chij' cov npib tshwj xeeb, chaw nyob lossis kev lag luam raws li ' pheej hmoo ' […] ua rau txhua tus neeg siv pom qhov pheej hmoo txawm tias ua ntej kev sim laundering."
Allan Liska, tus kws tshuaj ntsuam xyuas qib siab ntawm Recorded Future, hais rau Cointelegraph tias "Nws yeej yuav pab hauv kev tshuaj xyuas los ntawm blockchain forensic soj ntsuam. "Thaum cov pab pawg ransomware feem ntau hloov tawm lub hnab nyiaj rau txhua qhov kev tawm tsam ransomware, cov nyiaj ntawd thaum kawg ntws rov qab mus rau ib lub hnab nyiaj. Cov kws tshawb fawb Blockchain tau txais txiaj ntsig zoo ntawm kev sib txuas cov dots. " Lawv muaj peev xwm ua tau qhov no txawm tias sib xyaw thiab lwm cov tswv yim siv los ntawm ransomware rings thiab lawv cov koom haum pab nyiaj launderers, nws hais ntxiv.
Siddhartha Dalal, tus xibfwb ntawm kev xyaum ua haujlwm ntawm Columbia University, pom zoo. Xyoo tas los, Dalal tau sau ib daim ntawv hu ua "Qhia Ransomware Actors Hauv Bitcoin Network" uas tau piav qhia txog yuav ua li cas nws thiab nws cov neeg tshawb nrhiav tau siv cov duab kos tshuab kev kawm algorithms thiab blockchain tsom xam txhawm rau txheeb xyuas cov neeg tawm tsam ransomware nrog "85% kev kwv yees qhov tseeb ntawm cov ntaub ntawv sim."
Thaum lawv cov txiaj ntsig tau txhawb nqa, cov kws sau ntawv tau hais tias lawv tuaj yeem ua tiav qhov raug zoo dua los ntawm kev txhim kho lawv cov algorithms ntxiv thiab, qhov tseem ceeb, "tau txais cov ntaub ntawv ntau dua uas ntseeg tau ntau dua."
Qhov kev sib tw rau forensic modelers ntawm no yog hais tias lawv ua hauj lwm nrog heev imbalanced, los yog skewed, cov ntaub ntawv. Cov kws tshawb fawb Columbia University tuaj yeem kos tau 400 lab Bitcoin kev lag luam thiab ze rau 40 lab Bitcoin chaw nyob, tab sis tsuas yog 143 ntawm cov no tau lees paub qhov chaw nyob ransomware. Hauv lwm lo lus, kev lag luam uas tsis yog kev dag ntxias nyob deb tshaj qhov kev dag ntxias. Nrog cov ntaub ntawv raws li skewed li no, tus qauv yuav yog ib tug ntau ntawm cov cuav zoo los yog yuav tshem tawm cov ntaub ntawv dag raws li ib tug me feem pua.
Coinfirm's Bieda muab ib qho piv txwv ntawm qhov teeb meem no hauv kev xam phaj xyoo tas los:
"Hais tias koj xav tsim ib tus qauv uas yuav rub tawm cov duab ntawm cov dev los ntawm ib lub trove ntawm cov duab miv, tab sis koj muaj kev cob qhia dataset nrog 1,000 miv duab thiab tsuas yog ib daim duab dev xwb. Tus qauv kev kawm tshuab 'yuav kawm paub tias nws yog qhov zoo los kho tag nrho cov duab zoo li cov duab miv raws li qhov yuam kev yog [tsuas yog] 0.001.'"
Muab txwv tsis pub, lub algorithm yuav "tsuas yog kwv yees 'miv' txhua lub sijhawm, uas yuav ua rau tus qauv tsis muaj txiaj ntsig, tau kawg, txawm tias nws tau qhab nia siab ntawm qhov tseeb tag nrho."
Dalal tau nug yog tias tsab cai lij choj tshiab no hauv Teb Chaws Asmeskas yuav pab nthuav tawm cov ntaub ntawv pej xeem ntawm "kev dag ntxias" Bitcoin thiab cov chaw nyob crypto xav tau kom muaj txiaj ntsig zoo dua blockchain tsom xam ntawm ransomware tes hauj lwm.
"Tsis muaj lus nug txog nws," Dalal hais rau Cointelegraph. "Tau kawg, cov ntaub ntawv ntau dua yog ib txwm zoo rau txhua qhov kev tshuaj ntsuam." Tab sis qhov tseem ceeb tshaj plaws, raws li txoj cai, kev them nyiaj ransomware tam sim no yuav tshwm sim nyob rau hauv 24-teev sijhawm, uas tso cai rau "lub sijhawm zoo dua rau kev rov qab los thiab tseem muaj peev xwm txheeb xyuas cov servers thiab cov txheej txheem ntawm kev tawm tsam kom lwm tus neeg raug tsim txom tuaj yeem ua cov kauj ruam tiv thaiv. tiv thaiv lawv, ”nws hais ntxiv. Qhov ntawd yog vim tias feem ntau cov neeg ua txhaum cai siv tib yam malware los tua lwm tus neeg raug tsim txom.
Cov cuab yeej forensic underutilized
Nws feem ntau tsis paub tias kev cai lij choj tau txais txiaj ntsig thaum cov neeg ua phem siv cryptocurrencies los pab nyiaj rau lawv cov haujlwm. Kimberly Grauer, tus thawj coj ntawm kev tshawb fawb ntawm Chainalysis tau hais tias "Koj tuaj yeem siv kev tshuaj xyuas blockchain los nthuav tawm lawv tag nrho cov saw hlau ntawm kev ua haujlwm. "Koj tuaj yeem pom qhov twg lawv tab tom yuav lawv cov mos txwv hosting, qhov twg lawv yuav lawv cov malware, lawv koom nrog hauv Canada" thiab lwm yam. "Koj tuaj yeem tau txais kev nkag siab ntau rau cov pab pawg no" los ntawm kev txheeb xyuas blockchain, nws ntxiv ntawm Chainalysis Media Roundtable tsis ntev los no hauv New York City.
Tab sis, txoj cai no, uas tseem yuav siv sij hawm ntau lub hlis los siv, puas yuav pab tau tiag? "Nws yog qhov zoo, nws yuav pab tau," Salman Banaei, tus thawj coj ntawm pej xeem txoj cai ntawm Chainalysis, teb ntawm tib qhov xwm txheej. "Peb tau tawm tsam rau nws, tab sis nws tsis zoo li peb tau ya dig muag ua ntej." Nws puas yuav ua rau lawv cov kev tshawb fawb forensic muaj txiaj ntsig zoo dua? "Kuv tsis paub yog tias nws yuav ua rau peb muaj txiaj ntsig zoo dua, tab sis peb yuav cia siab tias qee qhov kev txhim kho ntawm cov ntaub ntawv npog."
Tseem muaj cov ntsiab lus tseem ceeb uas yuav tsum tau ua haujlwm hauv cov txheej txheem kev tswj hwm ua ntej txoj cai raug coj los siv, tab sis ib lo lus nug pom tseeb tau raug tsa: Cov tuam txhab twg yuav tsum ua raws? "Nws yog ib qho tseem ceeb kom nco ntsoov tias daim nqi no tsuas yog siv rau 'cov koom haum uas muaj lossis ua haujlwm tseem ceeb," Liska hais rau Cointelegraph. Thaum qhov ntawd tuaj yeem suav nrog kaum tawm txhiab lub koom haum thoob plaws 16 cov haujlwm, "qhov kev xav tau no tseem tsuas yog siv rau ib feem me me ntawm cov koom haum hauv Tebchaws Meskas."
Tab sis, tej zaum tsis yog. raws li rau Bipul Sinha, CEO thiab co-founder ntawm Rubrik, lub tuam txhab kev ruaj ntseg cov ntaub ntawv, cov kev tsim kho vaj tse nyob hauv txoj cai lij choj suav nrog kev pabcuam nyiaj txiag, IT, lub zog, kev kho mob, kev thauj mus los, kev tsim khoom thiab chaw ua lag luam. "Hauv lwm lo lus, tsuas yog hais txog txhua tus," nws sau hauv Fortune tsab xov xwm tsis ntev los no
Lwm lo lus nug: Yuav tsum tau tshaj tawm txhua qhov kev tawm tsam, txawm tias cov uas suav tias yog qhov tsis tseem ceeb? Cybersecurity thiab Infrastructure Security Agency, qhov chaw uas cov tuam txhab yuav tshaj tawm, tsis ntev los no tau tawm tswv yim tias txawm tias kev ua me me tuaj yeem suav tias tau tshaj tawm. "Vim tias muaj kev pheej hmoo pheej hmoo ntawm Lavxias teb sab cyberattacks [...] txhua qhov xwm txheej tuaj yeem muab cov qhob cij tseem ceeb ua rau tus neeg tawm tsam tsis zoo," New York Times qhia.
Puas yog nws tsim nyog xav tias kev ua tsov rog ua rau qhov yuav tsum tau ua kev tiv thaiv sai dua? Thawj Tswj Hwm Joe Biden, ntawm lwm tus, tau tsa qhov muaj feem cuam tshuam txog kev tawm tsam cyber-tawm los ntawm tsoomfwv Lavxias, tom qab tag nrho. Tab sis, Liska tsis xav tias qhov kev txhawj xeeb no tau nthuav tawm - tseem tsis tau, tsawg kawg:
"Kev ua pauj ransomware tawm tsam tom qab Lavxias kev tawm tsam ntawm Ukraine tsis zoo li tau tshwm sim. Zoo li ntau ntawm kev ua tsov ua rog, muaj kev sib koom ua haujlwm tsis zoo ntawm ib feem ntawm Russia, yog li txhua pab pawg ransomware uas tej zaum yuav raug mob tsis tau. "
Tseem, yuav luag peb-plaub ntawm tag nrho cov nyiaj tau los ntawm ransomware tawm tsam mus rau hackers txuas rau Russia xyoo 2021, raws li mus rau Chainalysis, yog li kev nce qib hauv kev ua si los ntawm qhov ntawd tsis tuaj yeem txiav txim tawm.
Tsis yog kev daws teeb meem ib leeg
Lub tshuab-kev kawm algorithms uas txheeb xyuas thiab taug qab ransomware cov neeg ua yeeb yam nrhiav kev them nyiaj blockchain - thiab yuav luag tag nrho cov ransomware yog blockchain enabled - yuav ua tsis tau zoo tam sim no, hais Bieda. Tab sis, cov kev daws teeb meem kev kawm tshuab tsuas yog "ib qho ntawm cov yam ntxwv txhawb nqa blockchain tsom xam thiab tsis yog ib qho kev daws teeb meem." Tseem muaj qhov xav tau tseem ceeb "rau kev koom tes dav hauv kev lag luam ntawm tub ceev xwm, blockchain tshawb xyuas cov tuam txhab, cov chaw muab kev pabcuam virtual thiab, tau kawg, cov neeg raug dag ntxias hauv blockchain."
Dalal ntxiv tias ntau qhov kev sib tw tseem nyob, feem ntau yog qhov tshwm sim ntawm qhov tshwj xeeb ntawm pseudo-tsis qhia npe, piav qhia rau Cointelegraph:
"Feem ntau cov pej xeem blockchains tsis tso cai thiab cov neeg siv tuaj yeem tsim ntau qhov chaw nyob raws li lawv xav tau. Cov kev hloov pauv tau ua ntau dua vim tias muaj cov tumblers thiab lwm cov kev pabcuam sib xyaw uas muaj peev xwm sib xyaw cov nyiaj tsis zoo nrog ntau lwm tus. Qhov no ua rau muaj kev sib koom ua ke ntawm kev txheeb xyuas cov neeg ua txhaum cai zais tom qab ntau qhov chaw nyob. "
Kev vam meej ntxiv?
Txawm li cas los xij, tej yam zoo li tau txav mus rau qhov raug. Liska hais ntxiv tias "Kuv xav tias peb tab tom ua kom muaj kev vam meej zoo li kev lag luam," thiab peb tau ua tiav sai heev." Ntau lub tuam txhab tau ua haujlwm tshiab hauv cheeb tsam no, "thiab Lub Tsev Haujlwm Saib Xyuas Nyiaj Txiag thiab lwm lub koomhaum tseemfwv tseem tab tom pib pom tus nqi hauv blockchain tsom xam."
Ntawm qhov tod tes, thaum kev tshuaj xyuas blockchain tau ua kom pom tseeb, "muaj nyiaj ntau tau ua los ntawm ransomware thiab cryptocurrency tub sab tam sim no uas txawm tias qhov cuam tshuam rau txoj haujlwm no tseem muaj daj ntseg piv rau tag nrho cov teeb meem," Liska ntxiv.
Thaum Bieda pom kev nce qib, nws tseem yuav yog qhov nyuaj kom tau txais cov tuam txhab tshaj tawm txog kev dag ntxias blockchain, tshwj xeeb tshaj yog sab nraud Tebchaws Meskas. "Rau ob xyoos dhau los, ntau dua 11,000 tus neeg raug tsim txom ntawm kev dag ntxias hauv blockchain tau mus txog Coinfirm los ntawm peb lub vev xaib Reclaim Crypto," nws hais. "Ib qho ntawm cov lus nug peb nug yog, 'Koj puas tau tshaj tawm cov tub sab tub nyiag rau tub ceev xwm?' - thiab ntau tus neeg raug tsim txom tsis tau. "
Dalal tau hais tias tsoomfwv txoj cai tswjfwm yog ib kauj ruam tseem ceeb hauv kev coj ncaj ncees. "Qhov no yeej yuav yog qhov hloov pauv kev ua si," nws hais rau Cointelegraph, vim cov neeg tawm tsam yuav tsis tuaj yeem rov qab siv lawv cov tswv yim nyiam, "thiab lawv yuav tau txav nrawm dua los tua ntau lub hom phiaj. Nws tseem yuav txo qis kev qias neeg uas txuas nrog rau kev tawm tsam thiab cov neeg raug tsim txom yuav tuaj yeem tiv thaiv lawv tus kheej zoo dua. "
