The most common malware in November 2023 is the infostealer Formbook and the most frequently attacked industry is ISP/MSP. Command Injection Over HTTP was the most commonly exploited vulnerability.
Check Point Software Technologies has released its November 2023 Global Threat Index:
Top malware in Germany
First place in Germany was achieved by Formbook. Formbook is an infostealer that targets the Windows operating system and was first discovered in 2016. It is marketed in underground hacker forums as Malware-as-a-Service (MaaS) because it has powerful evasion techniques and is relatively inexpensive. New additions include fake updates. Nanocore is in third place.
*The arrows refer to the change in ranking compared to the previous month.
1. ↑ Formbook – Formbook is an infostealer that targets the Windows operating system and was first discovered in 2016. It is marketed on underground hacking forums as Malware-as-a-Service (MaaS) due to its strong evasion techniques and relatively low price.
