  • A new strain of ransomware called Goodwill, has unusual demands in exchange for the decryption key.

Web applications are the main entry points for breaches (over 40%). Credentials and personal data are the favorite data type of criminal actors because they are so useful for masquerading as legitimate users on the system. 80% of the breaches can be attributed to stolen credentials.

  • New Office vulnerability dubbed “Follina” allows code execution via Microsoft Diagnostic Tool without the need for macros. In RTF documents, the exploit works by just previewing the file. More

  • Latest iteration of XLoader malware uses a probability based approach to camouflage its Command-and-Control (C2) infrastructure. The stealthiness comes from the fact the domain name for the real C2 is hidden in a list of 64 decoy domains. The first eight domains are overwritten with new random values before each communication cycle while taking steps to skip the real domain. The real C2 server is accessed in every communication cycle, or once in approximately 80-90 seconds. After one million malware launches, only in one case the malware might not access the real C&C server in a period of 2.5 hours of run-time. More
