Ib pawg neeg nyiag nkas uas tau lees tias tau nkag mus rau Nvidia servers tab tom sim muag qee cov ntaub ntawv uas suav nrog txoj hauv kev los qhib cov ntawv teev lus rau Ethereum mining.
Thaum lub Ob Hlis lig, semiconductor loj Nvidia tau tshaj tawm tias nws tab tom tshawb xyuas qhov muaj peev xwm cyber-attack uas cuam tshuam rau qee qhov ntawm nws txoj kev lag luam online. Pab pawg neeg nyiag nkas LAPSUS$ tau lees paub lub luag haujlwm ntxiv tias lawv tau tswj hwm nyiag 1TB (ib terabyte) ntawm cov ntaub ntawv los ntawm tuam txhab servers.
Raws li lub khoos phis tawj kho vajtse PCmag, pab pawg tam sim no muab muag cov ntaub ntawv ntxiv rau cov ntsiab lus ntawm kev qhib lub siab kawg Nvidia GPUs rau crypto mining.
Cov hackers tau thov kom muaj cov software tsim kho uas muaj peev xwm yooj yim qhib Nvidia's "Lite Hash Rate" txwv rau nws cov ntawv RTX 3000 series graphics. Kev tshaj tawm xov xwm hauv zej zog los ntawm pab pawg nyob rau lub asthiv tau pom tias lawv tau muab dab tsi:
"Yog hais tias ib tug neeg yuav peb lub LHR, peb yuav muab txoj hauv kev [tsis nrog] LHR yam tsis muaj dab tsi flashing. Tsis muaj flashing = nyiaj loj rau ib tus miner tsim tawm. "
Nvidia hash tus nqi limiters
Hauv kev rau siab los txhawb cov neeg ua haujlwm crypto los ntawm kev yuav tag nrho lawv daim npav, thiab tawm qee qhov rau cov gamers, Nvidia tau qhia txog "Ethereum hash tus nqi limiter" thaum ntxov 2021 ntawm nws cov qauv flagship. Kev siv zog tsis ua haujlwm tiag tiag txij li cov miners tau yuav cov ntawv qub uas tseem muaj zog txaus rau kuv, ua rau qhov tsis txaus thiab xa GPU nqi saum ntuj-siab.
Cov hackers twb tau pov tseg 19GB (gigabytes) ntawm cov ntaub ntawv uas suav nrog cov cai rau GPU tsav tsheb thiab kev ua haujlwm rau tus lej hash limiter.
Cov pab pawg tau thov kom Nvidia nqa qhov txwv rau tag nrho nws cov qauv RTX 3000 los ntawm kev hloov kho software rau cov neeg siv khoom. Nws hem tias yuav xau cov ntaub ntawv ntau ntxiv yog tias lub tuam txhab tsis ua raws, qee qhov qhia meej Nvidia cov ntawv cim tom ntej, codenamed Ada, Hopper, thiab Blackwell.
Txawm li cas los xij, tsab ntawv ceeb toom ntxiv tias tam sim no pab pawg xav muag tus neeg tsav tsheb tawm tswv yim tias lawv tuaj yeem ua bluffing. Nvidia, uas tau pom cov nyiaj tau los cuam tshuam txog kev lag luam poob qis hauv Q4, tsis tau teb rau lawv qhov kev thov thiab tseem tab tom ntsuas cov ntaub ntawv ua txhaum cai.
Graphics card woes
Graphics phaib tseem mob heev thiab tsis txaus, ua rau gamers fuming ntawm miners. Qhov teeb meem ob-pronged ntawm kev sib kis-vim cov teeb meem kev xa khoom thiab crypto miners snapping lawv tag nrho tau ncua qhov teeb meem rau ob xyoos dhau los.
Qee lub tebchaws muaj qhov tsis txaus siab uas qhov kev lag luam thib ob uas muaj txiaj ntsig zoo tau tshwm sim qhov twg muaj daim npav hnub nyoog peb xyoos mus rau ntau dua li cov nqi qub. Nvidia lub sab saum toj kawg nkaus GeForce RTX 3090 tuaj yeem raug nqi ntau npaum li $ 2,000, thiab ntau dua ntawm qee lub khw Asian.
