Viral Activity in September 2018: A Month of Digital Threats
September 2018 was a month marked by a surge in digital threats, with several viruses and malware making headlines. This article delves into the key viruses that went around in September 2018, their impact, and the lessons learned.
Triada Banking Trojan: The September Starter
The month began with the resurgence of the Triada banking trojan, which had been dormant since 2017.

Its reemergence served as a stark reminder of the persistent nature of cyber threats.
VPNFilter: The Router-Based Menace
In mid-September, a sophisticated malware strain named VPNFilter infected over 500,000 routers and network-attached storage (NAS) devices worldwide. Discovered by Cisco Talos, VPNFilter was capable of collecting sensitive data, launching denial-of-service attacks, and even bricking infected devices. The malware's complexity and scale highlighted the growing threat posed by IoT devices.
SamSam Ransomware: The $6 Million Heist
Towards the end of the month, the SamSam ransomware made headlines again, this time netting its operators an estimated $6 million in Bitcoin. Targeting organizations rather than individual users, SamSam encrypted critical data and demanded hefty ransoms for its return.
