Hacker group uses Solaris zero-day to breach corporate networks. The zero-day appears to have been bought off a black-market website for $3,000.

Mandiant, the investigations unit of security firm FireEye, has published details today about a new threat actor it calls UNC1945 that the security firm says it used a zero-day vulnerability in the Oracle Solaris operating system as part of its intrusions into corporate networks.
Regular targets of UNC1945 attacks included the likes of telecommunications, financial, and consulting companies, the Mandiant team said in a report published today.
Old group, new zero-day
While UNC1945 activity went as far back as 2018, Mandiant said the group caught their eye earlier this year after the threat actor utilized a never-before-seen vulnerability in the Oracle Solaris operating system.
Tracked as CVE-2020-14871, the zero-day was a vulnerability in the Solaris Pluggable Authentication Module (PAM) that allowed UNC1945 to bypass authentication procedures and install a backdoor named SLAPSTICK on internet-exposed Solaris servers.
Mandiant said the hackers then used this backdoor as an entry point to launch reconnaissance operations inside corporate networks and move laterally to other systems.
To avoid detection, Mandiant said the group downloaded and installed a QEMU virtual machine running a version of the Tiny Core Linux OS.
This custom-made Linux VM came pre-installed with several hacking tools like network scanners, password dumpers, exploits, and reconnaissance toolkits that allowed UNC1945 to scan a company's internal network for weaknesses and move laterally to multiple systems, regardless if they ran Windows or *NIX-based systems.
unc1945.png Image: FireEye Mandiant said it observed the group using an assortment of open-source penetration testing and security tools, but also custom malware strains.
The open-source toolkits included the likes of Mimikatz, Powersploit, Responder, Procdump, CrackMapExec, PoshC2, Medusa, and the JBoss Vulnerability Scanner, all well-known in the cyber-security industry.
But UNC1945 also showed the ability to create and operate custom malware, with Mandiant linking UNC1945 intrusions to (new and old) malware strains like:
EVILSUN - a remote exploitation tool that gains access to Solaris 10 and 11 systems of SPARC or i386 architecture using a vulnerability (CVE-2020-14871) exposed by SSH keyboard-interactive authentication. The remote exploitation tool makes SSH connections to hosts passed on the command line. The default port is the normal SSH port (22), but this may be overridden. EVILSUN passes the banner string SSH-2.0-Sun_SSH_1.1.3 over the connection in clear text as part of handshaking. LEMONSTICK - a Linux executable command line utility with backdoor capabilities. The backdoor can execute files, transfer files, and tunnel connections. LEMONSTICK can be started in two different ways: passing the -c command line argument (with an optional file) and setting the 'OCB' environment variable. When started with the -c command line argument, LEMONSTICK spawns an interactive shell. When started in OCB mode, LEMONSTICK expects to read from STDIN. The STDIN data is expected to be encrypted with the blowfish algorithm. After decrypting, it dispatches commands based on the name—for example: 'executes terminal command', 'connect to remote system', 'send & retrieve file', 'create socket connection'. LOGBLEACH - an ELF utility that has a primary functionality of deleting log entries from a specified log file(s) based on a filter provided via command line. OKSOLO - a publicly available backdoor that binds a shell to a specified port. It can be compiled to support password authentication or dropped into a root shell. OPENSHACKLE - a reconnaissance tool that collects information about logged-on users and saves it to a file. OPENSHACKLE registers Windows Event Manager callback to achieve persistence. ProxyChains - allows the use of SSH, TELNET, VNC, FTP and any other internet application from behind HTTP (HTTPS) and SOCKS (4/5) proxy servers. This "proxifier" provides proxy server support to any application. PUPYRAT (aka Pupy) - an open source, multi-platform (Windows, Linux, OSX, Android), multi-function RAT (Remote Administration Tool) and post-exploitation tool mainly written in Python. It features an all-in-memory execution guideline and leaves very low footprint. It can communicate using various transports, migrate into processes (reflective injection), and load remote Python code, Python packages and Python C-extensions from memory. STEELCORGI - a packer for Linux ELF programs that uses key material from the executing environment to decrypt the payload. When first starting up, the malware expects to find up to four environment variables that contain numeric values. The malware uses the environment variable values as a key to decrypt additional data to be executed. SLAPSTICK - a Solaris PAM backdoor that grants a user access to the system with a secret, hard-coded password. TINYSHELL - a lightweight client/server clone of the standard remote shell tools (rlogin, telnet, ssh, etc.), which can act as a backdoor and provide remote shell execution as well as file transfers. Zero-day bought off the black market?
Mandiant said it believes that UNC1945 bought EVILSUN (the tool that allowed them to exploit the Solaris zero-day and plant the SLAPSTICK backdoor) from a public hacking forum.
The company said it identified an ad in April 2020 on a black-market website that promoted an "Oracle Solaris SSHD Remote Root Exploit" for $3,000.
Mandiant said it reported the Solaris zero-day to Oracle earlier this year, after discovering traces of exploitation during an investigation.
The zero-day (CVE-2020-14871) was patched last month in Oracle's October 2020 security patches.
Mandiant said that while UNC1945 has been active for several years, it spotted the Solaris zero-day in one confirmed breach; however, this doesn't mean the zero-day wasn't exploited against other corporate networks.
The security firm said it "did not observe evidence of data exfiltration and was unable to determine UNC1945's mission for most of the intrusions [they] investigated."
In one UNC1945 intrusion, ransomware was deployed as a final payload, but Mandiant couldn't link the ransomware attack to UNC1945 directly, and "is likely that access to the victim environment was sold to another group."
Indicators of compromise and other technical details describing UNC1945 operations and intrusion patterns are available for defenders in the Mandiant report here.

The day I brought down $OnlineBookSeller

Many moons ago, I was working as a Linux and NetBackup admin for a large online book store.
We were doing a migration to the newest version (v4.0 IIRC) and spent many weeks planning and preparing for the move.
On the day of the move, we staged all of the new NetBackup config files and clients on the servers and prepared for the cutover. We started going through the different servers, bringing up the new clients and verifying that data was flowing to the NB server and then to the LTO4 tape libraries.
As the day progressed, we were feeling pretty good about the migration and perhaps weren't quite as vigilant about the migration as we should have been. Everything to date had been a success and it looked like it was a perfectly executed move.
About 3PM I cut over the large HP cluster that ran the backbone Oracle DB server for the entire site. This was the main DB. It wasn't the only DB, but this was the prime one.
The new client started up and everything looked great. I verified that there was data going to the NB server and moved on.
Stayed at work that night until about 6PM just to make sure that there were no hiccups. Nothing out of the ordinary raised its head and I went home, mentally patting myself on the back for a migration well done.
At home I was just relaxing and unwinding after a stressful day when suddenly my pager started going crazy. These were the types of alerts you never want to see: "$OnlineBookSeller site completely down".
Dialed into a conference call with the lead techs from across the company and the C*Os who were not belligerent, but definitely wanted to know WTF was happening and why the entire site was down. It was estimated that we were losing several million dollars for every minute that the site was down, and they made sure to keep us on task.
The primary Oracle DBA discovered that the main DB was DOA. I started to get a bad feeling about this.
For those that don't know much about Oracle, it basically has 3 different types of files. 1. The DB itself (usually a raw disk partition for speed but it can be a file also), 2. The "archive" logs, and 3. The "redo" logs.
The archive and redo logs are basically Oracle's trail of all the changes that it made in the exact order that it made them. This way, if the DB gets corrupted, it can be rebuilt by loading and replaying the logs. (Yes, this is a very simplified overview).
The job of NetBackup was to grab the archive and redo logs and back them up to tape so that if something bad happened, we wouldn't lose everything.
Because of a small typo in the config file which I had pre-staged, NB was backing up the archive and redo logs, but it was not deleting them from the file system once they were backed up.
So Oracle happily went about its business, creating the logs and doing its thing. NB was happily backing them up. But, once the file system filled up because the old logs weren't being deleted, Oracle just threw its hands in the air and quit.
We ended up being down for about 45 minutes while the DBA frantically moved logs around and I was validating that the logs were safe to be deleted as they had been backed up.
During this whole time, the C*Os were on the phone, not being mean or nasty, but letting us know that this was not a good situation.
Finally, 45 minutes later, everything was back up and we ended the call. I was trembling because I thought that this was definitely a Resume Generating Event. Slept badly all night.
Got in to work the next morning and $manager was standing outside the building waiting for me to come to work. As I got out of my car, he just stood there, glowering at me and not saying anything. I was feeling pretty worried.
Suddenly, he got a huge sh*t eating grin on his face, shook my hand and said "Congratulations, you're no longer a virgin." Laughed and walked me inside.
I did end up having to spend about 30 minutes on the phone with the CEO explaining what happened and kinda groveling for my job, but it all worked out and I stayed an employee there for about another year.
TL;DR Make sure you delete your Oracle logs after you back them up
