- Modern ransomware like Nefilim present new challenges and security concerns for enterprises across the world. How do these new families differ from traditional ransomware? And what can organizations do to mitigate risks?The 4G/5G campus network demonstrates the growing role of telecom technologies in different industries. Organizations and IT/OT experts need to keep up with these changes and consider their security implications.Industrial control systems (ICSs) are integral to smart factories, but gaps in the security of these systems could be exploited by malicious actors for cyberattacks. Enterprises should therefore address weak links in ICSs in their cybersecurity strategy.The use of connected cars continues to grow. While the vehicles’ link to technologies such as 5G and the cloud present opportunities for improving efficiency and safety, it can also attract risks from threat actors as well.We analyzed the tools, relationships, and behaviors used in a long-standing intrusion of a company after its security team observed malicious C&C traffic.We discuss the present state of the malicious uses and abuses of AI and ML and the plausible future scenarios in which cybercriminals might abuse these technologies for ill gain.A critical asset that enterprises should give careful security consideration to is their back-end infrastructure which, if compromised, could lead to supply chain attacks.A watering hole campaign we dubbed as Operation Earth Kitsune is spying on users’ systems through compromised websites. Using SLUB and two new malware variants, the attacks exploit vulnerabilities including those of Google Chrome and Internet Explorer.Bulletproof hosting (BPH) services have long been crucial parts of the cybercriminal infrastructure. How do they protect malicious activities, and how do cybercriminals use them to stay in business?
