Businesses who interact with U.S. authorities were often targeted.
Attackers have increased the use of DocuSign as a phishing lure over the past two weeks.
According to SC US, DocuSign phishing URL utilisation increased by 98 percent over six days in November, compared with the entirety of September and October. According to a SlashNext Email Security report, one-fifth of the DocuSign phishing attacks during the two weeks involved the spoofing of U.S. government entities.
The researchers said these attacks were targeting businesses that regularly interact with state, municipal and licensing authorities in the United States.
“This sophisticated campaign is particularly dangerous because it exploits the trusted relationship between businesses and their regulatory bodies,” wrote the SlashNext researchers.
