Black Lotus Labs® releases threat intelligence report showing newly discovered watering hole attack that targeted Ukrainian, Canadian organizations
Attackers' tradecraft mimics that of recent hack of San Francisco International Airport websites
DENVER, April 5, 2021 /PRNewswire/ -- Black Lotus Labs, the threat intelligence arm of Lumen Technologies (NYSE: LUMN), today announced it has uncovered a cluster of compromised websites previously used in a series of watering hole attacks. Any visitors who browsed to one of the sites would unknowingly be infected and vulnerable to the threat actor stealing a copy of their Windows authentication credentials, which could be used to impersonate them. The activity, which was only recently discovered, was identified on several Ukrainian websites and one Canadian website in 2019 and 2020.
Watering hole attacks target websites by injecting a malicious function into the site's code, which the victims' machine then executes. These types of attacks have been used for years, including in a high-profile compromise that was detected on the San Francisco International Airport's (SFO) website in April 2020.
In its analysis of the attacks in Ukraine and Canada, Black Lotus Labs observed malicious activity that appeared to exhibit the same tradecraft as the San Francisco airport attack. As a result, the team has clustered the activity to the same actor.
To disrupt the attacks in Ukraine and Canada, Black Lotus Labs notified the owners of the compromised websites of these findings.
How the Attacks Were Executed
"Our mission is to leverage our network visibility to help protect our customers and keep the internet clean, so we will continue to monitor this actor and this type of watering hole activity," said Mike Benjamin, head of Black Lotus Labs. "To protect against this type of attack, organizations should configure their firewalls to prevent outbound SMB-based communications from leaving the network, or consider turning off or limiting SMB in the corporate environment."
