Venafi announced the findings of a dark web investigation into ransomware spread via malicious macros.

87% of the ransomware found on the dark web has been delivered via malicious macros to infect targeted systems.

In February, Microsoft announced a major change to combat the rapid growth of ransomware attacks delivered via malicious macros, but they temporarily reversed that decision in response to community feedback.

In addition to a variety of ransomware at various price points, the research also uncovered a wide range of services and tools that help make it easier for attackers with minimal technical skills to launch ransomware attacks.

Generic ransomware build services also command high prices, with some listings costing more than $900. At the other end of the price spectrum, many low-cost ransomware options are available across multiple listings - with prices starting at just $0.99 for Lockscreen ransomware.

"Using code signing certificates to authenticate macros means that any unsigned macros cannot execute, stopping ransomware attacks in its tracks," Bocek concludes.
