Intel 471 researchers have identified a new malicious document builder, dubbed “EtterSilent,” leveraged by various threat actor groups. One of the build options is a weaponized Microsoft Office document (maldoc) that uses malicious macros to download and execute an externally hosted payload. The maldocs pose as templates for DocuSign, a cloud-based electronic signature service.
‘More_eggs’ is a backdoor sold as a “malware-as-a-service” (MaaS) by a threat group known as “Golden Chickens” and predominantly used by three criminal groups: FIN6, Cobalt Group, and Evilnum.

Hot on the heels of 'Dearcry'[1], yet another ransomware threat has been observed as targeting Microsoft Exchange servers vulnerable to recently reported critical vulnerabilities[2]. Dubbed 'Black KingDom', this ransomware threat has reportedly been deployed through a web-shell that is installed on vulnerable Microsoft Exchange servers following the exploitation of the vulnerability chain that results in both remote code execution (RCE) and elevated privileges.
Organisations hit by ransomware attacks are finding themselves paying out more than ever before, according to a new report from Palo Alto Networks. The Unit 42 threat intelligence team at Palo Alto Networks teamed up with the incident response team at Crypsis to produce their latest threat report which looks at the latest trends in ransomware, and compares payment trends to previous years.
While freeware does not have monetary cost, it may come at a price. There may be limitations to freeware such as infrequent updates, limited support and hidden malicious software. Some freeware programs may have added software packages that can include malicious software such as trojans, spyware, or adware.
