Ransomware
According to cybersecurity company Emsisoft, ransomware attacks affected at least 948 government agencies, educational establishments and healthcare providers in the United States in 2019, at a potential cost exceeding $7.5 billion. In the medical sector, the potential effects of these kinds of attacks include patients being redirected to other hospitals, medical records being made inaccessible (or permanently lost) and emergency dispatch centers relying on printed maps and paper logs to keep track of emergency responders in the field. In government, local 911 services can be disrupted. And according to Manhattan D.A. Cyrus Vance Jr., the effect of ransomware could be as devastating and costly as a natural disaster like Hurricane Sandy.
What you need to know: Ransomware is an attack where an infected host encrypts a victim’s data, holding it hostage until they pay the attacker a fee. Recent ransomware attacks have demonstrated that hackers have begun threatening to leak or sell the stolen data, increasing the potential damage of these kinds of attacks by orders of magnitude. There are countless types of ransomware, but certain groups are especially nefarious. One well-known gang, Blackmatter, has targeted a number of organizations critical to the U.S. economy and infrastructure, including the food and agriculture industry. Ryuk is another type of ransomware to watch out for. As of 2019, Ryuk had the highest ransom on record at $12.5 million.
