Cybercriminals appear to be losing interest in the Cobalt Strike penetration testing suite for their evil deeds. Threat actors have found alternatives in the open-source, cross-platform kit, Sliver. Healthcare and education sectors are once again under increasing threat from a new ransomware family, dubbed Agenda by researchers. Its ransom amount ranges between $50,000 and $800,000. It is suspected that threat actors behind Agenda might be offering ransomware services to affiliates outside their group.

Besides, the CISA warned organizations and agencies to patch a critical ICS-based RCE vulnerability in one of Delta Electronics products used for designing and programming HMIs. Also, this product has reached EOL; it is advised to switch to supported software.

Delta Electronics’ bug in CISA’s book
The CISA added 10 security bugs to its Known Exploited Vulnerabilities Catalog, including a high-severity RCE flaw in the Delta Electronics DOPSoft 2 software. Tracked as CVE-2021-38406, it is an out-of-bounds write issue that can be exploited by making the targeted user open a malicious file. There is no data on the exploitation of the bug in the wild.

CERT-In points out flaw
A path traversal vulnerability in RarLab’s UnRAR may impact Linux and Unix systems, warned CERT-In. The bugs can be exploited to execute arbitrary code on the targeted systems. Additionally, a critical vulnerability in the Realtek software development kit was also highlighted. The zero-click bug exists due to improper bounds checking by the SIP ALG function. Users are requested to update their software to the patched version.
