As coverage of the blog post pointed out, the vulnerability draws into question whether Cellebrite's tools are reliable in criminal prosecutions after all. While Cellebrite has since taken steps to mitigate the vulnerability, there's already been a motion for a new trial filed in at least one criminal case on the basis of Signal's blog post.
Throughout their operations, the professional design and continued development of phishing elements in parallel to other post-compromise tools indicated to FireEye that FIN7 was most likely a well-resourced criminal operation.

LNK files can contain metadata that reveals attributes about the systems on which the LNKs were created, including original file paths, volume serial numbers, MAC addresses, and hostnames. By studying values within the LNK metadata we often identify "toolmarks," or unique values associated with distinct malware developer and operator personas.
Unlike most CTF forensics challenges, a real-world computer forensics task would hardly ever involve unraveling a scheme of cleverly encoded bytes, hidden data, mastroshka-like files-within-files, or other such brain-teaser puzzles. One would typically not bust a criminal case by carefully reassembling a corrupted PNG file, revealing a photo of a QR code that decodes to a password for a zip archive containing an NES rom that when played will output the confession. Rather, real-world forensics typically requires that a practictioner find indirect evidence of maliciousness: either the traces of an attacker on a system, or the traces of "insider threat" behavior. Real-world computer forensics is largely about knowing where to find incriminating clues in logs, in memory, in filesystems/registries, and associated file and filesystem metadata. Also, network (packet capture) forensics is more about metadata analysis than content analysis, as most network sessions are TLS-encrypted between endpoints now.
This disconnect between the somewhat artificial puzzle-game CTF "Forensics" and the way that forensics is actually done in the field might be why this category does not receive as much attention as the vulnerability-exploitation style challenges. It may also lack the "black hat attacker" appeal that draws many players to participate in CTFs. Regardless, many players enjoy the variety and novelty in CTF forensics challenges. It can also be a more beginner friendly category, in which the playing field is evened out by the fact that there are no $5,000 professional tools like IDA Pro Ultimate Edition with Hex-Rays Decompiler that would give a huge advantage to some players but not others, as is the case with executable analysis challenges.
Although the above tools should suffice, in some cases you may need to programmatically extract a sub-section of a file using Python, using things like Python's re or regex modules to identify magic bytes, and the zlib module to extract zlib streams.
Like image file formats, audio and video file trickery is a common theme in CTF forensics challenges not because hacking or data hiding ever happens this way in the real world, but just because audio and video is fun. As with image file formats, stegonagraphy might be used to embed a secret message in the content data, and again you should know to check the file metadata areas for clues. Your first step should be to take a look with the mediainfo tool (or exiftool) and identify the content type and look at its metadata.
Sometimes the challenge is not to find hidden static data, but to analyze a VBA macro to determine its behavior. This is a more realistic scenario, and one that analysts in the field perform every day. The aforementioned dissector tools can indicate whether a macro is present, and probably extract it for you. A typical VBA macro in an Office document, on Windows, will download a PowerShell script to %TEMP% and attempt to execute it, in which case you now have a PowerShell script analysis task too. But malicious VBA macros are rarely complicated, since VBA is typically just used as a jumping-off platform to bootstrap code execution. In the case where you do need to understand a complicated VBA macro, or if the macro is obfuscated and has an unpacker routine, you don't need to own a license to Microsoft Office to debug this. You can use Libre Office: its interface will be familiar to anyone who has debugged a program; you can set breakpoints and create watch variables and capture values after they have been unpacked but before whatever payload behavior has executed. You can even start a macro of a specific document from a command line:
In this hacking tutorial, we'll learn how to use RouterSploit, a tool for automating the process of router exploitation. But before we dive right in, let's get a little background information on the tools available and why router exploitation is so big.
While the CIA uses VPN connections to hide traffic to and from command-and-control servers, cybercriminals will use these devices to proxy malicious traffic to avoid detection. In fact, networks of these infected routers and IoT devices are sold as black market proxies for hiding illegal activity like credit card theft, darknet transactions, and DDoS attacks. By failing to secure your router, you could be signing up to relay traffic for criminal hacking enterprises.
If the exploit is successful, you should be greeted with internal configuration settings that can leak the login and password of users, default passwords, and device serial number, among other settings that allow you to compromise the router. Other modules allow you to remotely inject code or directly disclose the router password. Which you can run depends on what the target router is vulnerable to.
Below is the JtR command from our Live Cyber Attack Webinar. In this scenario, our hacker used kerberoast to steal a Kerberos ticket granting ticket(TGT) containing the hash to be cracked, which was saved in a file called ticket.txt. In our case, the wordlist used is the classic rockyou password file from Kali Linux, and the command was set to report progress every 3 seconds.
A data breach occurs when a cybercriminal infiltrates a data source and extracts confidential information. This can be done by accessing a computer or network to steal local files or by bypassing network security remotely. While most data breaches are attributed to hacking or malware attacks, other breach methods include insider leaks, payment card fraud, loss or theft of a physical hard drive of files, and human error. The most common cyber attacks used in data breaches are outlined below.
A Computer Forensic Investigation generally investigates the data which could be taken from computer hard disks or any other storage devices with adherence to standard policies and procedures to determine if those devices have been compromised by unauthorised access or not. Computer Forensics Investigators work as a team to investigate the incident and conduct the forensic analysis by using various methodologies (e.g. Static and Dynamic) and tools (e.g. ProDiscover or Encase) to ensure the computer network system is secure in an organization. A successful Computer Forensic Investigator must be familiar with various laws and regulations related to computer crimes in their country (e.g. Computer Misuse Act 1990, the UK) and various computer operating systems (e.g. Windows, Linux) and network operating systems (e.g. Win NT). According to Nelson, B., et al., (2008), Public Investigations and Private or Corporate Investigations are the two distinctive categories that fall under Computer Forensics Investigations. Public investigations will be conducted by government agencies, and private investigations will be conducted by private computer forensic team. This report will be focused on private investigations, since an incident occurred at a new start-up SME based in Luton.
Before carrying out any further processes, we need to image the disk bit by bit, which will access the entire volume and copy the original media, including the deleted files. After the disk is imaged, we should hash everything which will make sure that the data is authentic and the integrity of the data will be maintained throughout the investigation. The hash values must be recorded in multiple locations and we must ensure that we do not make any changes to the data from the time of collection of the data till the end of the investigation. Most tools help in achieving this by accessing the media in a read-only state (SANS, 2010). Target System Hard drives, External Storage devices, and the Windows NT Server Hard drive must be acquired for the digital forensic investigation in this case.
In the case study it is mentioned that a large amount of data is being sent out of the database, so now the task of the Fantastic team is to perform a forensic investigation on the database with the help of forensic tools. Database forensics focuses on the identification, preservation and analysis of data. According to Khanuja, H.K., and Adane, D.S., (2011), to access the database the users need to get permissions like authorization and authentication from the database servers. Once the authorization is done, only the user can access the data and if intended he/she can alter the data. Now if we check the audit logs of the database, we can get a list of the users who got permissions to access the data. The team needs to look up in the database for the IP addresses which are remotely connected, because there are chances of altering the data by the authorized user or unauthorized user.
Cell phone forensics has become an increasingly important part of criminal cases over the past decade, with law enforcement now utilizing entire departments dedicated to investigating digital evidence. In its most basic form, cell phone forensics involves gaining access to a victim's or suspect's phone in order to find evidence that might help solve the case. This can be in the form of phone calls, text messages, search history, location data and social media activity. 2ff7e9595c
