An increasing number of websites are asking visitors to approve “notifications,” browser modifications that periodically display messages on the user’s mobile or desktop device. In many cases these notifications are benign, but several dodgy firms are paying site owners to install their notification scripts and then selling that communications pathway to scammers and online hucksters.
Earlier today, KrebsOnSecurity alerted the 10th largest food distributor in the United States that one of its Web sites had been hacked and retrofitted with code that steals credit card and login data. While such Web site card skimming attacks are not new, this intrusion leveraged a sneaky new domain that hides quite easily in a hacked site’s source code: “http[.]ps” (the actual malicious domain does not include the brackets, which are there to keep readers from being able to click on it).
Multiple security firms recently identified cryptocurrency mining service Coinhive as the top malicious threat to Web users, thanks to the tendency for Coinhive’s computer code to be used on hacked Web sites to steal the processing power of its visitors’ devices.
