IT securitycyber defenseransomwareUnderstanding the Sony Hacker Indictment: IT Security Lessons from APT37
In August 2018, the US Department of Justice (DoJ) unsealed the indictment of a North Korean spy, Park Jin Hyok, whom they claim was behind the hack against Sony and the creation and distribution of the WannaCry ransomware. The 170-plus-page document was written by Nathan Shields of the FBI’s LA office and shows the careful sequence of forensic analysis they used to figure out how various attacks were conducted.. Security researchers have given Park’s organization various monikers, including the Lazarus Group, APT37, Lab 110, Group 123, Hidden Cobra, Nickel Academy and Reaper. Some are from the malware elements they created. That is the first thing that you will learn from the indictment: the North Koreans have been at the center of many different campaigns over the past six or so years.

incident responsesecurity toolsattack methodsSecurity Teams Urged to Adapt as Attack Methods Outpace Forensics
Attackers are using increasingly sophisticated methods to stay ahead of security incident response teams, says Kevin Mandia, security consultancy. In the never-ending cat-and-mouse game between hackers and those charged with stopping them, it's pretty clear who's winning--and it's not the cat. Speaking at the Black Hat conference in Las Vegas last week, Kevin Mandia, president of Mandiant, an Alexandria, Va.-based security consultancy, said attackers are using increasingly sophisticated methods to evade detection and make life difficult for security incident response teams. . The sophistication of hackers' tools is outpacing that of investigators' forensic tools, and one of the consequences is that incident response teams charged with investigating attacks on networks are taking between 5 and 8 days to find malicious code, Mandia said. "Malware analysis can be time consuming, and most firms don't want to spend the money to fully analyze the malicious code, which could cause further damage [to the network]," said Mandia. And because it can take days to find malicious code, Mandia said rumors of a kernel level rootkits always arise within the company that's being analyzed. Rootkits are software tools designed to hide running processes, files or system data and enable attackers to maintain control over a system without the user's knowledge. A kernel level rootkit takes this cloak of invisibility a step further by adding or modifying part of the kernel code. The link for this article located at Dr. Dobbs Journal is no longer available. .

Cooper, a computer forensics expert, learned that the numeral "1" had been scrubbed in some later versions of this digital document. This gave his client, a partner in a software company that had recently been sold, just a 5 percent rather than a 15 percent share in the company.

incident responsedata recoveryforensic analysisForensic Analysis Techniques for Live Linux Systems in Incident Response
During the incident response process we often come across a situation where a compromised system wasn't powered off by a user or administrator. This is a great opportunity to acquire much valuable information, which is irretrievably lost after powering off. I'm referring to things such as: running processes, open TCP/UDP ports, program images which are deleted but still running in main memory, the contents of buffers, queues of connection requests, established connections and modules loaded into part of the virtual memory that is reserved for the Linux kernel. All of this data can help the investigator in offline examination to find forensic evidence. Moreover, when an incident is still relatively new we can recover almost all data used by and activities performed by an intruder. . . .. During the incident response process we often come across a situation where a compromised system wasn't powered off by a user or administrator. This is a great opportunity to acquire much valuable information, which is irretrievably lost after powering off. I'm referring to things such as: running processes, open TCP/UDP ports, program images which are deleted but still running in main memory, the contents of buffers, queues of connection requests, established connections and modules loaded into part of the virtual memory that is reserved for the Linux kernel. All of this data can help the investigator in offline examination to find forensic evidence. Moreover, when an incident is still relatively new we can recover almost all data used by and activities performed by an intruder. Sometimes the live procedure described here is the only way to acquire incident data because certain types of malicious code, such as LKM based rootkits, are loaded only to memory and don't modify any file or directory. A similar situation exists in Windows operating systems -- the Code Red worm is a good example of this, where the malicious code was not saved as a file, but was inserted into and then run directory from memory. On the other hand, methodspresented below also have serious limitations and violate the primary requirement of the collection procedure for digital investigation -- a requirement which can not be easily fulfilled. That is: every user and kernel space tool used to collect data by nature changes the state of the target system. By running any tools on a live system we load them into memory and create at least one process which can overwrite possible evidence. By creating a new process, the memory management system of the operating system allocates data in main memory and then can overwrite other unallocated data in main memory or in the swap file system. Other problems arise when we plan to take legal actions and need to comply with local laws. The signs of intrusions found in images of main memory can be untrusted, because they could be created by our acquisition tools. So before taking any action we must decide whether to acquire some data from a live compromised system or not. It is very often worth it to collect such information. In the main memory image we can find passwords or decrypted files. Using /proc pseudo file system we can also recover programs that have been deleted but are still allocated in memory. In an ideal world, I could imagine a kind of hardware based solution for Intel-based computers, which would allow us to dump the whole memory to an external storage device without assistance of operating system. Such a solution exits on Sparc machines, whereby we can dump the whole physical memory by using the OpenBoot firmware. Unfortunately, no similar solution exists for Intel- or AMD-based computers. Despite the above problem, software based methods also have advantages for forensic purposes, and I'll try to show them in this paper. The main goal of this article is a presentation of methods used during an evidence collection procedure. All collected data can be used later to perform offline forensic analysis. Some of presented tasks can be also be performed in the preparation and identification phases of the incident responsecycle -- these are two of the six phases defined in a guide called "Incident Handling Step by step", published by the SANS Institute.

On December 2nd at approximately 03:45 UTC, one of the servers that makes up the rsync.gentoo.org rotation was compromised via a remote exploit. At this point, we are still performing forensic analysis. However, the compromised system had both an IDS and a file integrity checker installed and we have a very detailed forensic trail of what happened once the box was breached, so weare reasonably confident that the portage tree stored on that box wasunaffected. The attacker appears to have installed a rootkit and modified/deleted some files to cover their tracks, but left the server otherwise untouched. The box was in a compromised state for approximately one hour before it was discovered and shut down. During this time, approximately 20 users synchronized against the portage mirror stored on this box. The method used to gain access to the box remotely is still under investigation. We will release more details once we have ascertained the cause of the remote exploit. This box is not an official Gentoo infrastructure box and is instead donated by a sponsor. The box provides other services as well and the sponsor has requested that we not publicly identify the box at this time. Because the Gentoo part of this box appears to be unaffected by this exploit, we are currently honoring the sponsor's request. That said, if at any point, we determine that any file in the portage tree was modified in any way, we will release full details about the compromised server. SOLUTION: Again, based on the forensic analysis done so far, we are reasonablyconfident that no files within the Portage tree on the box were affected. However, the server has been removed from all rsync.*.gentoo.org rotations and will remain so until the forensic analysis has been completed and the box has been wiped and rebuilt. Thus, users preferring an extra level of security may ensure that they have a correct and accurate portage tree by running: emerge sync Which will perform a sync against another server and ensure that all files are up to date.
