More logging means it's easier than ever to execute the discovery course of action to identify earlier exploitation. I expect to see more evidence of pre-disclosure exploitation in the future. https://t.co/mxubEeckEF

The #Kinsing and #Muhstik cryptomining botnets are some of the first to exploit any new RCE vulnerability: this time it’s Log4j & Log4Shell. Those two names have cropped up for several major RCEs this year, they’ve actually become one way to tell how bad a new RCE is.

Earliest evidence we’ve found so far of #Log4J exploit is 2021-12-01 04:36:50 UTC. That suggests it was in the wild at least 9 days before publicly disclosed. However, don’t see evidence of mass exploitation until after public disclosure.

-4 major botnets spotted abusing Log4Shell right now (per Netlab)
-more than 10k hosts scanning for it (per Kryptos Logic)
-DDoS, crypto-miners, and CS beacons as payloads for nowhttps://t.co/oIm2wzNLHv pic.twitter.com/E9B42fKQY7

Approximately one year after the #SolarWinds Attack, the Apache #Log4j vulnerability has taken the #cybersecurity world by storm. @_CPResearch_ has witnessed new variations of the original exploit being introduced rapidly, over 60 in less than 24 hrs: https://t.co/BLlFxIflOj pic.twitter.com/KMQrUAowZU
— Check Point Software (@CheckPointSW) December 13, 2021
Unlike other major #cyberattacks, #Log4j is basically embedded in every #Java-based product or #webservice. This gives attackers many alternatives to bypass newly introduced protections rendering the exploit difficult to remediate: https://t.co/BLlFxHXKWL pic.twitter.com/H1UUcQUuXE

Log4Shell(CVE 2021- 4422)に対応するLog4j 2.15.0での脆弱性修正は不完全で、JEDIルックアップパターンによるDoSが可能。CVE 2021-45046が新たに発行されてて、Log4j 2.16.0はそのFix版とのこと。なるほど。https://t.co/zKcfGZUYdl https://t.co/a3iNDxrFzm

Not as bad as the first as it's requires non default configuration. #log4j https://t.co/UNnPBV0PgJ pic.twitter.com/4u98fjaBPl

We are not done yet. #log4j has been patched again as the previous fix was "incomplete in certain non-default configurations.". Upgrade to 2.16.0 instead of 2.15.0. Do the same for your vendor provided software. https://t.co/cA8lQ3C3QN
