2022-09-08 08:39:42 | Lazarus and the tale of three RATs (lien direct) |  By Jung soo An, Asheer Malhotra and Vitor Ventura.Cisco Talos has been tracking a new campaign operated by the Lazarus APT group, attributed to North Korea by the United States government. This campaign involved the exploitation of vulnerabilities in VMWare Horizon to gain an initial foothold into targeted organizations.Targeted organizations include energy providers from around the world, including those headquartered in the United States, Canada and Japan. The campaign is meant to infiltrate organizations around the world for establishing long term access and subsequently exfiltrating data of interest to the adversary's nation-state.Talos has discovered the use of two known families of malware in these intrusions - VSingle and YamaBot.Talos has also discovered the use of a recently disclosed implant we're calling "MagicRAT" in this campaign. IntroductionCisco Talos observed North Korean state-sponsored APT Lazarus Group conducting malicious activity between February and July 2022. Lazarus has been previously attributed to the North Korean government by the U.S. Cybersecurity and Infrastructure Security Agency (CISA). The entry vectors involve the successful exploitation of vulnerabilities in VMWare products to establish initial footholds into enterprise networks, followed by the deployment of the group's custom malware implants, VSingle and YamaBot. In addition to these known malware families, we have also discovered the use of a previously unknown malware implant we're calling "MagicRAT."This campaign was previously partially disclosed by other security firms, but our findings reveal more details about the adversary's modus operandi. We have also observed an overlap of command and control (C2) and payload-hosting infrastructure between our findings and the U.S. Cybersecurity and Infrastructure Security Agency's (CISA) June advisory that detailed continued attempts from threat actors to compromise vulnerable VMWare Horizon servers.In this research, we illustrate Lazarus Group's post-exploitation tactics, techniques and procedures (TTPs) to establish a foothold, perform initial reconnaissance, deploy bespoke malware and move laterally across infected enterprises. We also provide details about the activities performed by the attackers when the VSingle backdoor is instrumented on the infected endpoints.In this campaign, Lazarus was primarily targeting energy companies in Canada, the U.S. and Japan. The main goal of these attacks was likely to establish long-term access into victim networks to conduct espionage operations in support of North Korean govern |

2022-09-07 08:01:43 | MagicRAT: Lazarus\' latest gateway into victim networks (lien direct) |  By Jung soo An, Asheer Malhotra and Vitor Ventura.Cisco Talos has discovered a new remote access trojan (RAT) we're calling "MagicRAT," developed and operated by the Lazarus APT group, which the U.S. government believes is a North Korean state-sponsored actor.Lazarus deployed MagicRAT after the successful exploitation of vulnerabilities in VMWare Horizon platforms.We've also found links between MagicRAT and another RAT known as "TigerRAT," disclosed and attributed to Lazarus by the Korean Internet & Security Agency (KISA) recently.TigerRAT has evolved over the past year to include new functionalities that we illustrate in this blog. Executive SummaryCisco Talos has discovered a new remote access trojan (RAT), which we are calling "MagicRAT," that we are attributing with moderate to high confidence to the Lazarus threat actor, a state-sponsored APT attributed to North Korea by the U.S. Cyber Security & Infrastructure Agency (CISA). This new RAT was found on victims that had been initially compromised through the exploitation of publicly exposed VMware Horizon platforms. While being a relatively simple RAT capability-wise, it was built with recourse to the Qt Framework, with the sole intent of making human analysis harder, and automated detection through machine learning and heuristics less likely.We have also found evidence to suggest that once MagicRAT is deployed on infected systems, it launches additional payloads such as custom-built port scanners. Additionally, we've found that MagicRAT's C2 infrastructure was also used to host newer variants of known Lazarus implants such as TigerRAT. The discovery of MagicRAT in the wild is an indication of Lazarus' motivations to rapidly build new, bespoke malware to use along with their previously known malware such as TigerRAT to target organizations worldwide.Actor profile |

WannaCry is a ransomware worm that spread rapidly through across a number of computer networks in May of 2017. After infecting a Windows computer, it encrypts files on the PC's hard drive, making them impossible for users to access, then demands a ransom payment in bitcoin in order to decrypt them.A number of factors made the initial spread of WannaCry particularly noteworthy: it struck a number of important and high-profile systems, including many in Britain's National Health Service; it exploited a Windows vulnerability that was suspected to have been first discovered by the United States National Security Agency; and it was tentatively linked by Symantec and other security researchers to the Lazarus Group, a cybercrime organization that may be connected to the North Korean government.To read this article in full, please click here | Ransomware Vulnerability Medical | Wannacry Wannacry APT 38 | |

APT-C-35: New Windows Framework Revealed
(published: August 11, 2022)
The DoNot Team (APT-C-35) are India-sponsored actors active since at least 2016. Morphisec Labs researchers discovered a new Windows framework used by the group in its campaign targeting Pakistani government and defense departments. The attack starts with a spearphishing RTF attachment. If opened in a Microsoft Office application, it downloads a malicious remote template. After the victim enables editing (macroses) a multi-stage framework deployment starts. It includes two shellcode stages followed by main DLL that, based on victim fingerprinting, downloads a custom set of additional information-stealing modules.
Analyst Comment: The described DoNot Team framework is pretty unique in its customisation, fingerprinting, and module implementation. At the same time, the general theme of spearphishing attachment that asks the targeted user to enable editing is not new and can be mitigated by anti-phishing training and Microsoft Office settings hardening.

2022-07-07 08:14:35 | North Korean State-Sponsored Threat Actors Deploying "MAUI" Ransomware (lien direct) | Today, the United States Federal Bureau of Investigation (FBI), Cybersecurity and Infrastructure Agency (CISA) and the Department of Treasury released a joint Cybersecurity Advisory on Maui Ransomware, which is attributed to state sponsored activity by the government of North Korea. The Joint CSA provides detailed insight on the various TTPs used by the threat actors behind Maui, which has targeted the Health and Public Health Sector.How Serious of an Issue is This?High. As ransomware activity causes downtime, theft of confidential and personally identifiable information (PII) and other significant impact to operations, it is important to ensure that various security measures are in place, like being up to date with patching vulnerable machines/infrastructure. Also, ensuring employees are trained and up to date on various social engineering attempts and tactics used by threat actors will be a first line of defense against such attacks.What is Maui Ransomware?Maui ransomware is unique in a way that it requires manual execution to start the encryption routine. Maui also features a CLI (command line interface) that is used by the threat actor to target specific files to encrypt. Maui also has the ability to identify previously encrypted files due to customer headers containing the original path of the file.Who are HIDDEN COBRA/LAZARUS/APT38/BeagleBoyz?HIDDEN COBRA also known as Lazarus/APT38/BeagleBoyz has been atributed to the government of North Korea. Also, they have been linked to multiple high-profile, financially-motivated attacks in various parts of the world - some of which have caused massive infrastructure disruptions. Notable attacks include the 2014 attack on a major entertainment company and a 2016 Bangladeshi financial institution heist that almost netted nearly $1 Billion (USD) for the attackers. Had it not been for a misspelling in an instruction that caused a bank to flag and block thirty transactions, HIDDEN COBRA would have pulled off a heist unlike any other. Although HIDDEN COBRA failed in their attempt, they were still able to net around 81 million dollars in total.The most recent notable attack attributed to HIDDEN COBRA was the Wannacry Ransomware attack, which resulted in massive disruption and damage worldwide to numerous organizations, especially those in manufacturing. Various estimates of the impact were in the hundreds of millions of dollars, with some estimates claiming billions. Other verticals which this group has targeted include critical infrastructures, entertainment, finance, healthcare, and telecommunication sectors across multiple countries.Who are the BeagleBoyz?The BeagleBoyz group is a newly identified group that is a subset of activity by the threat actors known as HIDDEN COBRA/LAZARUS/APT 38 and has been observed committing financial crimes, specifically cryptocurrency related thefts. Further information about the BeagleBoyz can be found here.What Operating Systems are Affected?Windows based operating systems are affected.What is the Status of Coverage?Fortinet customers running the latest definitions are protected against Maui with the following (AV) signatures:W32/Ransom_Win32_MAUICRYPT.YACC5W32/Agent.C5C2!trW32/PossibleThreatAnything Else to Note?Victims of ransomware are cautioned against paying ransoms by such organizations as CISA, NCSC, the FBI, and HHS. Payment does not guarantee files will be recovered. It may also embolden adversaries to target additional organizations, encourage other criminal actors to engage in the distribution of ransomware, and/or fund illicit activities which could potentially be illegal according to a U.S. Department of Treasury's Office of Foreign Assets Control (OFAC) advisory. | Ransomware Threat Patching Medical | Wannacry Wannacry APT 38 | |

SocGholish and Zloader – From Fake Updates and Installers to Owning Your Systems
(published: April 25, 2022)
Cybereason researchers have compared trending attacks involving SocGholish and Zloader malware. Both infection chains begin with social engineering and malicious downloads masquerading as legitimate software, and both lead to data theft and possible ransomware installation. SocGholish attacks rely on drive-by downloads followed by user execution of purported browser installer or browser update. The SocGholish JavaScript payload is obfuscated using random variable names and string manipulation. The attacker domain names are written in reverse order with the individual string characters being put at the odd index positions. Zloader infection starts by masquerading as a popular application such as TeamViewer. Zloader acts as information stealer, backdoor, and downloader. Active since 2016, Zloader actively evolves and has acquired detection evasion capabilities, such as excluding its processes from Windows Defender and using living-off-the-land (LotL) executables.
Analyst Comment: All applications should be carefully researched prior to installing on a personal or work machine. Applications that request additional permissions upon installation should be carefully vetted prior to allowing permissions. Additionally, all applications, especially free versions, should only be downloaded from trusted vendors.

Lazarus Targets Chemical Sector
(published: April 14, 2022)
In January 2022, Symantec researchers discovered a new wave of Operation Dream Job. This operation, attributed to the North Korea-sponsored group Lazarus, utilizes fake job offers via professional social media and email communications. With the new wave of attacks, Operation Dream Job switched from targeting the defense, government, and engineering sectors to targeting South Korean organizations operating within the chemical sector. A targeted user executes an HTM file sent via a link. The HTM file is copied to a DLL file to be injected into the legitimate system management software. It downloads and executes the final backdoor: a trojanized version of the Tukaani project LZMA Utils library (XZ Utils) with a malicious export added (AppMgmt). After the initial access, the attackers gain persistence via scheduled tasks, move laterally, and collect credentials and sensitive information.
Analyst Comment: Organizations should train their users to recognize social engineering attacks including those posing as “dream job” proposals. Organizations facing cyberespionage threats should implement a defense-in-depth approach: layering of security mechanisms, redundancy, fail-safe defense processes.

Phorpiex botnet is back with a new Twizt: Hijacking Hundreds of crypto transactions
(published: December 16, 2021)
Check Point Research has uncovered a new variant of the Phorpiex botnet named Twizt. Historically, Phorpiex utilized sextortion, ransomware delivery, and cryptocurrency clipping. Twizt however, appears to be primarily focused on stealing cryptocurrency and have stolen half a million dollars since November 2020 in the form of Bitcoin, Ether and ERC20 tokens.The botnet features departure from it’s traditional command and control (C2) infrastructure, opting for peer-to-peer (P2P) communications between infected hosts, eliminating the need for C2 communication as each host can fulfill that role.
Analyst Comment: Bots within a P2P network need to communicate regularly with other bots to receive and share commands. If the infected bots are on a private network, private IP addresses will be used. Therefore, careful monitoring of network traffic will reveal suspicious activity, and a spike in network resource usage as opposed to the detection of C2 IP addresses.

Regulations & Ransomware: A Quick OverviewAn overview of what enterprises need to know about ransomware and related regulations.Read More (lien direct) |
As cybersecurity threats continue to evolve, ransomware has recently come into focus as one of the more prominent and challenging types of attacks to deal with. Not only do companies need to face the security implications of having their data fall into the hands of cybercriminals, but there can be significant costs around paying ransoms and/or recovering systems and files. Plus, paying ransoms can raise some ethical if not legal issues. There are already several existing regulations that enterprises need to keep in mind if hit with a ransomware attack. And as the risk grows, a number of new regulations are under consideration around the world.In this brief overview, weâll explore what enterprises need to know about ransomware and related regulations.What Is Ransomware?Before diving into what to do about ransomware and what regulations to follow, itâs important to understand what ransomware is.âRansomware is a form of malware designed to encrypt files on a device, rendering any files and the systems that rely on them unusable. Malicious actors then demand ransom in exchange for decryption,â explains the U.S. Cybersecurity & Infrastructure Security Agency (CISA).In other words, ransomware can lock a user out of their own files/systems, which can bring work to a halt. Even if the ransom is paid and everything gets unlocked, itâs possible that the cybercriminals stole data meanwhile. While some of the more headline-grabbing attacks have been at large, well-known companies, ransomware can essentially affect anyone, regardless of size, industry or location.How to Reduce the Risk of RansomwareAlthough ransomware is on the rise, there are still several steps organizations can take to reduce the risk of a ransomware attack or at least mitigate the damage.âAs with all risks posed by external actors, the likelihood that a ransomware attack is successful can be drastically reduced by tightening the security of the data controlling environment,â notes the European Data Protection Board (EDPB).From updating software and systems with appropriate security patches, to using anti-malware software or related monitoring services, there are many cybersecurity best practices that can potentially keep ransomware out, as the EDPB highlights.If ransomware does take hold, having complete backups can help. As the EDPB notes, the impact of ransomware âcould effectively be contained,â by resetting systems to wipe out the ransomware and then âfixing the vulnerabilities and restoring the affected data soon after the attack.âOrganizations can also get a better handle on ransomware risk via cyber risk quantification (CRQ), such as through Kovrrâs insurance-validated risk models. CRQ works by analyzing factors such as past cyber events and the technologies and service providers that a company uses to then quantify what companies might lose if a cyber attack like ransomware occurs. Part of being prepared means knowing how much is at stake financially, and CRQ can help organizations focus on the areas that present the largest financial risk. âWhat Ransomware Regulations Exist?Current ransomware regulations differ around the world, so the specific rules an enterprise needs to follow depends on factors like what markets they operate in and whether they fall under certain jurisdictions.Communicating AttacksOne of the more notable rules that relates to ransomware is the EUâs General Data Protection Regulation (GDPR), which can still apply to companies outside Europe, such as those that have customers in the EU. Under GDPR, explains the EDPB, a personal data breach needs to be reported to relevant authorities and potentially to the people whose data gets exposed. So, for example, if a ransomware incident involves a cybercriminal locking up files that contain personal information, such as financial or medical records, then the affected company may need to report that to those affected.In the U.S. the | Ransomware Data Breach Malware Vulnerability Prediction Medical | ★★★ | |

Executive summary
AT&T Alien Labs™ has observed new activity that has been attributed to the Lazarus adversary group potentially targeting engineering job candidates and/or employees in classified engineering roles within the U.S. and Europe. This assessment is based on malicious documents believed to have been delivered by Lazarus during the last few months (spring 2021). However, historical analysis shows the lures used in this campaign to be in line with others used to target these groups.
The purpose of this blog is to share the new technical intelligence and provide detection options for defenders. Alien Labs will continue to report on any noteworthy changes.
Key Takeaways:
Lazarus has been identified targeting defense contractors with malicious documents.
There is a high emphasis on renaming system utilities (Certutil and Explorer) to obfuscate the adversary’s activities (T1036.003).
Background
Since 2009, the known tools and capabilities believed to have been used by the Lazarus Group include DDoS botnets, keyloggers, remote access tools (RATs), and drive wiper malware. The most publicly documented malware and tools used by the group actors include Destover, Duuzer, and Hangman.
Analysis
Several documents identified from May to June 2021 by Twitter users were identified as being linked to the Lazarus group. Documents observed in previous campaigns lured victims with job opportunities for Boeing and BAE systems. These new documents include:
Rheinmetall_job_requirements.doc: identified by ESET Research.
General_motors_cars.doc: identified by Twitter user @1nternaut.
Airbus_job_opportunity_confidential.doc: identified by 360CoreSec.
The documents attempted to impersonate new defense contractors and engineering companies like Airbus, General Motors (GM), and Rheinmetall. All of these documents contain macro malware, which has been developed and improved during the course of this campaign and from one target to another. The core techniques for the three malicious documents are the same, but the attackers attempted to reduce the potential detections and increase the faculties of the macros.
First iteration: Rheinmetall
The first two documents from early May 2021 were related to a German Engineering company focused on the defense and automotive industries, Rheinmetall. The second malicious document appears to include more elaborate content, which may have resulted in the documents going unnoticed by victims.
The Macro has base64 encoded files, which are extracted and decoded during execution. Some of the files are split inside the Macro and are not combined until the time of decoding. One of the most distinctive characteristics of this Macro is how it evades detections of a MZ header encoded in base64 (TVoA, TVpB, TVpQ, TVqA, TVqQ or TVro), by separating the first two characters from the rest of the content, as seen in Figure 1.
Figure 1: Concealing of MZ header, as captured by Alien Labs.
The rest of the content is kept together in lines of 64 characters, and because of this, YARA rules can be used to detect other, typical executable content encoded in base64 aside of the MZ header. In this case, up to nine different YARA rules alerted to suspicious encoded strings in our Alien Labs analysis, like VirtualProtect, GetProcAddress, IsDe |

Analyst Comment: Malware as a Service (MaaS) is a relatively new development, which opens the doors of crime to anyone with the money to pay for access. A criminal organization that wants to carry out a malware attack on a target no longer requires in-house technical expertise or infrastructure. Such attacks in most cases share tactics, techniques, and even IOCs. This highlights the importance of intelligence sharing for proactive protection.

Evolution of JSWorm Ransomware
(published: May 25, 2021)
JSWorm ransomware was discovered in 2019, and since then different variants have gained notoriety under different names such as Nemty, Nefilim, and Offwhite, among others. It has been used to target multiple industries with the largest concentration in engineering, and others including finance, healthcare, and energy. While the underlying code has been rewritten from C++ to Golang (and back again), along with revolving distribution methods, JSWorm remains a consistent threat.
Analyst Comment: Ransomware threats often affect organisations in two ways. First encrypting operational critical documents and data. In these cases EDR solutions will help to block potential Ransomwares and data backup solutions will help for restoring files in case an attack is successful. Secondly, sensitive customer and business files are exfiltrated and leaked online by ransomware gangs. DLP solutions will help to identify and block potential data exfiltration attempts. Whereas network segregation and encryption of critical data will play an important role in reducing the risk.
