www.carbonblack.com/2020/06/15/tau-threat-analysis-relations-to-hakbit-ransomware/ During a recent investigation into Hakbit ransomware, TAU decided to hit the “pause” button and take some time out to investigate this particular ransomware variant. The research methodology and findings are discussed within this report. From a single sample, and using some of the extracted metadata contained in this sample, we were able to pivot across some of those data points in order to uncover a total of 10 related ransomware families.

Quarterly report: Incident Response trends in Summer 2020

blog.talosintelligence.com/2020/06/CTIR-trends-q3-2020.html For the fourth quarter in a row, Ryuk dominated the threat landscape in incident response. As we mentioned in last quarter’s report, Ryuk has shifted from relying on commodity trojans to using living-off-the-land tools. This has led to a decrease in observations of attacks leveraging commodity trojans. Email remained the top infection vector, though we observe increased compromises of remote desktop services (RDS) as well as Citrix devices and Pulse VPN. One of the more interesting trends this quarter was the role of the COVID-19 pandemic. Interestingly, we did not observe any engagements in which COVID-19 was used in an attack. However, CTIR has observed the pandemic impacting organizations, affecting their ability to respond and contain cybersecurity incidents.
