New Trends in Ransomware, Network Infrastructure Attacks, Commodity Loader Malware

The Cisco Talos Year in Review report reveals changes in cybersecurity threats, including increased ransomware attacks, network infrastructure attacks and commodity loader malware. The healthcare sector was a key target for ransomware groups due to their access to protected health information. The Clop ransomware group notably exploited zero-day vulnerabilities. Cybercriminals are also focusing on data theft extortion more than encryption. Network infrastructure attacks grew in 2023, with China and Russia-based groups predominantly involved. Commodity loader malware adapted to be more stealthy, with several discarding their banking trojan capabilities.
