Cynnydd o 300% mewn achosion o ddwyn hunaniaeth ar-lein o gymharu \u00e2 2010<\/h3>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Yn \u00f4l y cwmni gwirio credyd, Experian, cafodd 12 miliwn o ddarnau o wybodaeth bersonol eu cyfnewid ar-lein gan dwyllwyr yn ystod chwarter cyntaf 2012, sy’n gynnydd o 300% ers 2010.<\/strong><\/p>\n

Yn \u00f4l y BBC, dywedodd Experian nad oedd llawer o bobl yn ymwybodol bod eu hunaniaeth wedi’i dwyn nes bod cwmn\u00efau’n gwrthod rhoi cardiau credyd neu gontractau ff\u00f4n symudol iddynt.<\/p>\n

Fel rheol, bydd y sawl y mae eu hunaniaeth wedi’i dwyn yn gweld bod cwmn\u00efau’n gwrthod rhoi benthyciadau neu gardiau credyd iddynt (14%), bod dyledion yn cronni yn eu henw (9%), bod cwmn\u00efau’n gwrthod rhoi contractau ff\u00f4n symudol iddynt (7%) a bod casglwyr dyledion yn eu herlid am ddyled nad ydynt wedi mynd iddi (7%).<\/p>\n

Dywedodd Experian fod y cynnydd mewn achosion o ddwyn hunaniaeth wedi digwydd yn rhannol oherwydd bod pobl yn cofrestru ar gyfer nifer gynyddol o gyfrifon ar-lein.<\/p>\n

Rhan o’r broblem hefyd yw bod gan lawer o ddefnyddwyr 26 o gyfrifon ar-lein, ar gyfartaledd, ond mai dim ond tua\u00a0phum cyfrinair gwahanol y maent yn eu defnyddio.<\/p>\n

Dylech newid eich cyfrineiriau’n rheolaidd a dylech sicrhau eu bod yn fwy cymhleth er mwyn ei gwneud hi’n anos i dwyllwyr eu darganfod.<\/p>\n

 <\/p>\n

Cynghorion er mwyn atal achosion o ddwyn hunaniaeth<\/h4>\n
    \n
  1. Dylech bob amser ddewis cyfrineiriau cryf ac unigryw, ac yn ddelfrydol dylent gynnwys cymysgedd o rifau a llythrennau a nodau arbennig megis ? neu !.<\/li>\n
  2. Byddwch yn ofalus wrth ddefnyddio eich cyfrif mewn mannau cyhoeddus, yn enwedig ar gyfrifiaduron a rennir.<\/li>\n
  3. Byddwch yn ofalus wrth rannu gwybodaeth bersonol, oherwydd gall y wybodaeth honno gael ei defnyddio i geisio cael mynediad i gyfrifon.<\/li>\n
  4. Gosodwch raglenni atal firysau, ysb\u00efwedd a maleiswedd, a sicrhewch fod y rhaglenni hynny’n cael eu diweddaru’n gyson.<\/li>\n
  5. Sicrhewch fod hidlwyr gwe-rwydo\u00a0eich porwr yn weithredol.<\/li>\n
  6. Sicrhewch eich bod ar y wefan gywir cyn nodi gwybodaeth bersonol.<\/li>\n<\/ol>\n

    Mae methu \u00e2 newid cyfrineiriau, neu ddefnyddio’r un cyfrinair ar gyfer sawl cyfrif, yn arfer peryglus oherwydd mae ymchwil wedi dangos ei bod yn haws i hacwyr gael mynediad i gyfrifon sy’n segur.<\/p>\n

    Cafodd defnyddwyr Yahoo eu cynghori gan gynrychiolwyr y diwydiant diogelwch i newid eu holl gyfrineiriau ar \u00f4l i hacwyr dorri i mewn i weinyddion y cwmni a dwyn 453,000 o gyfrineiriau a oedd yn perthyn i gyfrifon segur yn bennaf.<\/p>\n

    Dywedodd Eric Doer, sy’n rheolwr rhaglenni gr\u0175p i system gyfrifon Microsoft, fod achosion o danseilio\u00a0diogelwch sy’n arwain at ddatgelu gwybodaeth am gyfrifon cwsmeriaid er mwyn i droseddwyr ei chamddefnyddio yn amlygu’r broblem graidd, sef bod pobl yn defnyddio’r un cyfrineiriau ar draws amryw wefannau.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

    “Mae hynny’n pwysleisio pwysigrwydd yr un hen gyngor ynghylch diogelwch, sef y dylai pobl ddefnyddio cyfrineiriau unigryw, oherwydd mae troseddwyr bellach yn gweithredu mewn modd mwy soffistigedig o lawer ac yn cymryd rhestr o enwau defnyddwyr a chyfrineiriau oddi ar un gwasanaeth ac yn ‘ailchwarae’ y rhestr honno yn erbyn systemau cyfrifon mawr eraill.”<\/p>\n

    “Pan fyddant yn dod o hyd i gyfrineiriau sy’n cyfateb i’w gilydd, maent yn gallu lledaenu eu camddefnydd y tu hwnt i’r system gyfrifon wreiddiol y gwnaethant ymosod arni.”<\/p>\n

    A oes gan eich cwmni gyfarwyddiadau clir i’r staff ynghylch sicrhau diogelwch eich TG, defnyddio TG yn briodol, defnyddio cyfrineiriau diogel, cadw cop\u00efau wrth gefn o ffeiliau a chofrestru’n briodol er mwyn cydymffurfio \u00e2’r Ddeddf Diogelu Data?
