  • After being fired from a New York credit union, a former revengeful employee deleted 21 GB of data from the company’s file server, including loan applications and highly sensitive information.

Vulnerabilities and Patches

  • Check Point Research has recently exposed a new Out-Of-Bounds read-write vulnerability, tracked as CVE-2020-1910, in the WhatsApp instant messaging app. The issue, which could have allowed a sophisticated attacker to read sensitive information from WhatsApp memory, was subsequently patched.
  • Threat actors are currently exploiting the Atlassian Confluence remote code execution vulnerability that was recently unveiled, aiming at installing crypto miners. The vulnerability, tracked as CVE-2021-26084, allows a user to execute arbitrary code on a Confluence Server or Data Center instance.
  • Sixteen vulnerabilities dubbed BrakTooth are affecting Bluetooth stacks on system-on-a-chip and could impact billions of varied devices including industrial equipment. The vulnerabilities could allow a threat actor a range of possibilities, including the ability to execute malware on a device.
  • Cisco has announced patching a severe authentication bypass vulnerability (CVE-2021-34746) in its Enterprise Network Function Virtualization Infrastructure Software (NFVIS) which could have allowed a remote attacker to circumvent authentication and log into a vulnerable device as an administrator.

Threat Intelligence Reports

  • The Conti ransomware gang playbook that was published by an affiliate of the group last month has been translated to English, and delivers many insights into the attackers’ methods.

  • The FIN7 cybercrime gang has launched a new campaign using Windows 11 theme lures. The group targeted the point-of-sale provider Clearmind, with malicious Microsoft Word documents that include a VBA macro, and made sure that the targets were not from one of the CIS countries.
  • The FBI has released a special warning saying that ransomware gangs are aggressively targeting the food and agricultural sectors that could not only cause financial damage but also impact food supply chains like restaurants, markets, farms, or producers.
  • The FBI and CISA jointly warn of the higher risk of ransomware attacks during weekends and holidays, especially when company’s offices are closed.
