Malicious Script That Gets Rid of ADS, (Wed, Apr 1st)

Today, most malware are called “fileless” because they try to reduce their footprint on the infected computer filesystem to the bare minimum. But they need to write something… think about persistence. They can use the registry as an alternative storage location.

Application Control Bypass for Data Exfiltration, (Tue, Mar 31st)

In case of a cyber incident, most organizations fear more of data loss (via exfiltration) than regular data encryption because they have a good backup policy in place. If exfiltration happened, it means a total loss of control of the stolen data with all the consequences (PII, CC numbers, …).

DShield (Cowrie) Honeypot Stats and When Sessions Disconnect, (Mon, Mar 30th)

A lot of the information seen on DShield honeypots [1] is repeated bot traffic, especially when looking at the Cowrie [2] telnet and SSH sessions. However, how long a session lasts, how many commands are run per session and what the last commands run before a session disconnects can vary. Some of this information could help indicate whether a session is automated and if a honeypot was fingerprinted. This information can also be used to find more interesting honeypot sessions.
