‘Yahoo visitors may have been hacked’ – ‘Mashable’
Patrick Kulp says, “Yahoo played the unwitting host to a week’s worth of malware-laden scams in what may be the largest attack of its kind in months, security firm Malwarebytes claimed.
Researchers said the attackers infiltrated the web portal’s advertising network and planted traps on its homepage — along with its sports, finance, celebrity and games sites. When visitors came by the sites, the ads discreetly downloaded malware files to the visitor’s computer, either directly from the webpage or from a harmful site to which the ads diverted visitors.
The batch of parasitic ads first appeared on the site last Tuesday and may have affected millions of Yahoo users in the ensuing week, according to the firm, though only Yahoo can gauge the exact count.
In a statement, Yahoo said that it had successfully shut down the offending advertisers after the firm alerted it to the problem. The company also charged the firm with exaggerating the extent of the threat“.
