Blackfog’s October ransomware report has just been published. October was the 3rd largest month for ransomware this year with a total of 64 disclosed and 303 undisclosed attacks with a ratio of 473% unreported to reported. This ratio is now one of the lowest we have seen in the last year and a good sign that companies are starting to report breaches rather than hide them. We expect this trend to continue with the recent charges against the SolarWinds CISO by the SEC.
Other notable changes this month saw the biggest changes in the Services and Government sectors with 33% and 25% increases respectively. Smaller increases were seen in both Healthcare and Manufacturing of 16% and 13% respectively.
BlackCat and Lockbit continue to dominate the unreported attacks with 18.8% and 16.9% respectively and also correlate with the top trends in unreported variants. As in previous months, data exfiltration continues to dominate as the primary mechanism for extortion at 90% with traffic flowing to China at 32% and Russia 9% of the time.
