The second cyber attacks timeline of November 2021 is finally out (you can find the first one here or in the link below.) In the second half of this month I have collected 96 events, with a daily average slightly decreasing to 6.4 events/day from 6,9 events/day. Ransomware continues to dominate the threat landscape with a percentage of events directly or indirectly characterized similar to the previous timeline (22%)

Even the impact of vulnerabilities is similar to the previous timeline (10.4% vs 12%), and once again threat actors continue to exploit the ProxyShell and Zoho’s ManageEngine ADSelfService Plus vulnerabilities.

The season of the mega breaches continue and multiple organizations suffered multi-million breaches (browse the timeline for details.) The good news is that, at least in this timeline, I did not record any mega hack of a fintech platform (but I have the feeling that this will change in the next timeline).

Threat actors motivated by cyber espionage were quite active in November characterizing a record of 22% of events in this timeline. The list is really too crowded this timeline so I encourage you to browse it and discover the old acquaintances and the new comers that characterized this period.

The “Breachometer” compares the current number of events/day with the max and min values recorded in the previous 12 months.
