NSA publishes advisory on 25 vulnerabilities used by Chinese state sponsored hackers

October 23, 2020/in Basefarm SIRT, Security blog, SIRT /by Basefarm

The National security Agency in the United States recently released an advisory warning of the threat of Chinese state sponsored attacks and detailed 25 vulnerabilities used. The advisory gives detailed information about the vulnerabilities, what it affects and how to remediate them. Most of them are remotely exploited and can be used to gain initial access to a system before using other vulnerabilities to go further in to the network. Most of these vulnerabilities already have patches ready to be installed so as always we really want to emphasize keeping systems up to date with the latest patches and software.

Currently the biggest exposure to threats in the cyber domain is presented via mail. Phishing attacks tricks out the credentials for legitimate users and then gain access to the mail account, and some actors will sit with this access to months looking for ways to benefit from this access. As a way of establishing persistence an attacker will often create rules in the mail-system to have mail forwarded to an external account the attacker controls. This way, even if you change passwords, the attacker still receives copies of the mail.

These forwarding rules can serve as valuable indicators. And even if absence of evidence is not evidence of absence, it is worth to look for these rules with regular intervals. This is nothing new, but a reminder seemed in place given the current threat landscape. Here is an older blogpost from Compass-Security explaining the issue.

There is also a project on Github to help faciliate testing and low-volume activity data acquisition from the Office 365 Management Activity API that might be interesting in this regard.

Pen Test Partners has a great blog-post about one of their recent adventures.

This is a little bit out of the normal scenario for many, but this is regarding a finding they did on a ship. This is a good reminder to all to cover critical control number 1, inventory and control of hardware assets. It is not so easy to track this down on the spot when you got unlabeled shielded cables and deck penetration to deal with, no known paperwork or invoices related to the thing they found. They have a nice write up of what they did, what considerations they had to make.

Spoiler: In the end they figure out it is an outdated Windows machine, complete with TeamViewer installed, originating from a contract that had been expired for several years. And this machine had direct connection to the main engine of the ship.
