Watering hole attack
Watering hole is a computer attack strategy, in which the victim is a particular group (organization, industry, or region). In this attack, the attacker guesses or observes which websites the group often uses and infects one or more of them with malware. Eventually, some member of the targeted group becomes infected. Hacks looking for specific information may only attack users coming from a specific IP address. This also makes the hacks harder to detect and research. The name is derived from predators in the natural world, who wait for an opportunity to attack their prey near watering holes.
Websites are often infected through zero-day vulnerabilities on browsers or other software. A defense against known vulnerabilities is to apply the latest software patches to remove the vulnerability that allowed the site to be infected. This is assisted by users monitoring to ensure that all of their software is running the latest version. An additional defense is for companies to monitor their websites and networks and then block traffic if malicious content is detected.
2018 Chinese country-level attack
There was a country-level watering-hole attack in China from late 2017 into March 2018, by the group "LuckyMouse, also known as Iron Tiger, EmissaryPanda, APT 27 and Threat Group-3390."
2017 Ccleaner attack
From August to September 2017 the installation binary of Ccleaner distributed by the vendor's download servers included malware. Ccleaner is a popular tool used to clean potentially unwanted files from Windows computers, widely used by security-minded users. The distributed installer binaries were signed with the developer's certificate making it likely that an attacker compromised the development or build environment and used this to insert malware.
2017 ExPetr attack
In June 2017 the NotPetya (also known as ExPetr) malware, believed to have originated in the Ukraine, compromised a Ukrainian government website. The attack vector was from users of the site downloading it. The malware erases the contents of victims' hard drives.
2016 Polish banks
In late 2016, a Polish bank discovered malware on computers belonging to the institution. It is believed that the source of this malware was the web server of the Polish Financial Supervision Authority. There have been no reports on any financial losses as a result of this hack.
2013 US Department of Labor
In early 2013, attackers used the United States Department of Labor website to gather information on users' information. This attack specifically targeted users visiting pages with nuclear-related content.
2012 US Council on Foreign Relations
In December 2012, the Council on Foreign Relations website was found to be infected with malware through a zero-day vulnerability in Microsoft's Internet Explorer. In this attack, the malware was only deployed to users using Internet Explorer set to English, Chinese, Japanese, Korean and Russian.
