While the organizations yet to cope with the hard-hitting SolarWinds attack, another supply chain attack has landed on security experts’ investigation list. Dubbed as NightScout, the cyber-espionage operation was targeted at BigNox to deliver three malware families to victims in five countries, including Taiwan, Hong Kong, and Sri Lanka.

A clever tech support scam with unique evasion techniques has also come to the light of researchers. As a part of the scam, the phishers are manipulating Google search results to push malicious Home Depot ads.

Top Scams Reported in the Last 24 Hours

Tech support scam
A malicious Home Depot advertising campaign has been found redirecting Google Search visitors to tech support scams. Once visitors click on the ad, they are redirected through various ad services that ultimately end up on a page that displays an annoying message that reads ‘Windows Defender - Security Warning.’ To make detection more difficult for security professionals, it appears that the ads only redirect to the scam once every 24 hours to the same IP address.
