El mes de maig passat un enorme ciberatac<\/strong> va colpejar milers de sistemes inform\u00e0tics a desenes de pa\u00efsos i va afectar molts equips de xarxa de m\u00e9s de 70 pa\u00efsos. El ransomware<\/strong> no t\u00e9 com a objectiu robar dades sin\u00f3 causar un segrest expr\u00e9s xifrant els fitxers de l'equip infectat per posteriorment demanar un rescat via BitCoins, en aquest cas 300 USD<\/strong>. Aquest es distribueix amb un dropper enlla\u00e7at a un correu electr\u00f2nic que no \u00e9s detectat per molts motors d'antimalware.
 
Les an\u00e0lisis de l'Institut Nacional de Ciberseguretat (INCEB<\/strong>) d'Espanya recollien que el programari malici\u00f3s que va provocar ciberatac<\/strong> a nivell global \u00e9s un WanaCrypt0r, una variant de WCry\/WannaCry.
Aquest atac es va neutralitzar despr\u00e9s de la difusi\u00f3 d'un pegat de Windows per part de Microsoft.

Qu\u00e8 passa en instal\u00b7lar-se al nostre equip?<\/h2>\n\n\n\n

 
Despr\u00e9s d'instal\u00b7lar-se a l'equip, aquest virus bloqueja l'acc\u00e9s als fitxers de l'ordinador afectat demanant rescat per permetre l'acc\u00e9s. WanaCrypt0r xifra fitxers del disc dur amb extensions com .doc .dot .tiff .java .psd .docx .xls .pps .txt o .mpeg, entre d'altres, i augmenta la quantia del rescat a mesura que passa el temps.
 <\/p>\n\n\n\n

Qu\u00e8 fem despr\u00e9s d'un ciberatac?<\/h2>\n\n\n\n

 
L'Incibe, a trav\u00e9s del CERT de Seguretat i Ind\u00fastria (CERTSI<\/strong>), disposa d'un servei gratu\u00eft d'an\u00e0lisi i desxiframent de fitxers afectats per certs tipus de ransomware. La v\u00edctima pot contactar amb el servei a trav\u00e9s del correu incidencias@certsi.es<\/a>.
 <\/p>\n\n\n\n

Paguem per recuperar els nostres arxius?<\/h2>\n\n\n\n

 
L'Incibe recomana no pagar el rescat, perqu\u00e8 no hi ha garanties de recuperar les dades i la v\u00edctima pot patir atacs posteriors. L'Institut tamb\u00e9 assenyala que aquesta pr\u00e0ctica fomenta el negoci dels ciberdel\u00b7liq\u00fcents, que poden comen\u00e7ar a demanar xifres m\u00e9s altes, un cop efectuat el primer pagament.
 <\/p>\n\n\n\n

Com desinfectem l'ordinador?<\/h2>\n\n\n\n

 
Per eliminar la infecci\u00f3 es podria utilitzar qualsevol antivirus o antivirus autoarrencable actualitzat. \u00c9s recomanable fer un clonat previ dels discos (c\u00f2pia de la informaci\u00f3 del disc dur en un altre suport), segons la import\u00e0ncia de les dades afectades.
 
Un cop m\u00e9s, aquest atac demostra que el ransomware<\/strong> \u00e9s una poderosa arma que es pot utilitzar contra els consumidors i les empreses per igual.<\/p>","protected":false},"excerpt":{"rendered":"
