De asemenea, o alta masura eficienta pentru securizarea sistemului o reprezinta configurarea browserului astfel incat continutul ce depinde de un anumit plugin sa nu fie executat in mod automat, ci doar atunci cand se da click pe acesta.<\/p>\n<p><a href=\"http:\/\/www.securityweek.com\/malvertising-campaign-infected-visitors-yahoo-other-sites-ransomware\">Sursa<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cercetatorii de la Proofpoint au descoperit o campanie de malvertising care a afectat mai multe site-uri de profil inalt, inclusiv domenii precum Yahoo.com, Match.com si AOL.
