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 6,67 events/day. Ransomware continues to dominate the threat landscape but the percentage of events directly or indirectly characterized dropped to 22% from 30.6% of the previous timeline (but despite the decrease, the criminals are still asking for massive ransoms.) I wonder if this is an effect of the increasing pressure of the law enforcement agencies against the ransomware syndicates.

Another common trend of this period is the impact of vulnerabilities: in this timeline they characterized the 12% of events including several ransomware attacks. We have, among the others, a new 0-day for Android (CVE-2021-1048), the Tortilla threat actor exploiting ProxyShell to deploy the Babuk ransomware, and several widespread operations exploiting Zoho’s ManageEngine ADSelfService Plus CVE-2021-4053 (and yes, threat actors continue to exploit SolarWinds’ Serv-U CVE-2021-35211.

Robinhood had the information of approximately 7 million customers compromised, and another decentralized finance (DeFi) platform has bitten the dust, suffering the theft of $55 million worth of crypto assets by a suspected North Korean threat actor.

As usual, the cyber espionage front is quite crowded, a threat actor dubbed DEV-0322 has been very busy to exploit the ManageEngine vulnerability, the Lazarus Group never misses a timeline, along with other well known threat actors such as Lyceum and Kimsuky. Another important cyber espionage campaign characterizing this timeline is the PhoneSpy spyware targeting Android users in South Korea.

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