Top Malware Incidents Reported in the Last 24 Hours

Lucky ransomware spotted
Lucky, a malware variant of Satan ransomware is found spreading via different vulnerabilities in Windows and Linux server platforms. The malware spreads on its own with no human interaction and exploits known flaws in Windows SMB, JBoss, WebLogic, Apache Struts 2, and Spring Data Commons. The ransomware encrypts files and appends the ‘.lucky’ extension to the encrypted files.

Cloudera Hadoop flaws exploited
Two new strains of malware – Xbash and DemonBot – are found targeting Apache Hadoop servers for Bitcoin mining and DDoS purposes. They scan the internet vigorously for Hadoop clusters that are connected to the Internet and don’t use Kerberos authentication. The flaw in Hadoop is said to exist as the system is not properly configured and secured. But the attack techniques are not sophisticated and use known exploits. The targeted Hadoop servers are directly connected to open internet and they don’t have Kerberos authentication enabled. Hence, users must use a strong Kerberos authentication to check for the right access of privileged users.
