Malware

Overheard at the SANS Security Awareness Summit 2022

People have become the primary attack vector for cyber attackers around the world. As the Verizon Data Breach Investigations Report 2022 indicates, it is humans rather than technology that now represent the greatest risk to organizations. According to the SANS 2022 Security Awareness Report, the top three security risks that security professionals are concerned about are phishing, business email compromise (BEC) and ransomware, all closely related to human behavior.

Government Agencies vs. Ransomware: A National Emergency

Before your feathers are completely ruffled, understand that by no means am I minimizing the impact cybercriminals can have on a business. But have you considered attacks of greater scale?

Lorenz Ransomware Intrusion: Understanding Your Risk

The Arctic Wolf Labs team recently investigated a Lorenz ransomware intrusion, which leveraged a Mitel MiVoice VOIP appliance vulnerability (CVE-2022-29499) for initial access and Microsoft’s BitLocker Drive Encryption for data encryption. Lorenz is a ransomware group that has been active since at least February 2021 and like many ransomware groups, performs double-extortion by exfiltrating data before encrypting systems. Over the last quarter, the group has primarily targeted small and medium businesses (SMBs) located in the United States, with outliers in China and Mexico.
