Alert (AA22-294A) #StopRansomware: Daixin Team
(published: October 21, 2022)
Daixin Team is a double-extortion ransomware group that has been targeting US businesses, predominantly in the healthcare sector. Since June 2022, Daixin Team has been encrypting electronic health record services, diagnostics services, imaging services, and intranet services. The group has exfiltrated personal identifiable information and patient health information. Typical intrusion starts with initial access through virtual private network (VPN) servers gained by exploitation or valid credentials derived from prior phishing. They use SSH and RDP for lateral movement and target VMware ESXi systems with ransomware based on leaked Babuk Locker source code.
Analyst Comment: Network defenders should keep organization’s VPN servers up-to-date on security updates. Enable multifactor authentication (MFA) on your VPN server and other critical accounts (administrative, backup-related, and webmail). Restrict the use of RDP, SSH, Telnet, virtual desktop and similar services in your environment.

Exbyte: BlackByte Ransomware Attackers Deploy New Exfiltration Tool
(published: October 21, 2022)
Symantec detected a new custom data exfiltration tool used in a number of BlackByte ransomware attacks. This infostealer, dubbed Exbyte, performs anti-sandbox checks and proceeds to exfiltrate selected file types to a hardcoded Mega account. BlackByte ransomware-as-a-service operations were first uncovered in February 2022. The group’s recent attacks start with exploiting public-facing vulnerabilities of ProxyShell and ProxyLogon families. BlackByte removes Kernel Notify Routines to bypass Endpoint Detection and Response (EDR) products. The group uses AdFind, AnyDesk, Exbyte, NetScan, and PowerView tools and deploys BlackByte 2.0 ransomware payload.

2022-10-18 08:41:18 | The benefits of taking an intent-based approach to detecting Business Email Compromise (lien direct) |  By Abhishek Singh.BEC is a multi-stage attack. Adversaries first identify targets, then they establish rapport with the victim before exploiting them for whatever their end goal is. In the case of BEC, a threat actor can impersonate any employee in the organization to trick targets. A policy that checks for authorized email addresses of the sender can prevent BEC attacks. However, scaling the approach for every employee in a large organization is a challenge. Building an executive profile based on email analysis using a machine learning model and scanning emails against that profile will detect BEC. Data collection for building and training machine learning algorithms can take time, though, opening a window of opportunity for threat actors to exploit. Detection of exploitation techniques such as lookalike domains and any differences in the email addresses in the "From" and "Reply-to" fields can also detect BEC messages. However, the final verdict cannot account for the threat actor's intent. The intent-based approach detects BEC and then classifies it into the type of scam. It catches BEC messages, irrespective of whether a threat actor is impersonating a C-level executive or any employee in an organization. Classification based on the type of scam can help identify which segment of an organization was targeted and which employees were being impersonated by the threat actor. The additional information will further assist in better designing preventive features to stop BEC. Business email compromise (BEC) is one of the most financially damaging online crimes. As per the internet crime 221 report, the total loss in 2021 due to BEC is around 2.4 billion dollars. Since 2013, BEC has resulted in a 43 billion dollars loss. The report defines BEC as a scam targeting businesses (not individuals) working with foreign suppliers and companies regularly performing wire transfer payments. Fraudsters carry out these sophisticated scams to conduct the unauthorized transfer of funds. This introduces the challenge of how to detect and block these campaigns as they continue to compromise organizations successfully. There are a variety of approaches to identifying BEC email messages, such as using policy to allow emails from authorized email addresses, detecting exploitation techniques used by threat actors, building profiles by analysis of emails, and validating against the profile to detect BEC. These approaches have a variety of limitations or shortcomings. Cisco Talos is taking a different approach and using an intent-based model to identify and block BEC messages. Before we get too deep into the intent-based model, take a deeper look at the commonly used approaches to block BEC from the simplistic through machine learning (ML) approaches. Policy-based detection The first place to start is with policy-based detection as it is one of the most common and simplistic approaches to blocking BEC campaigns. Let's start by looking at an example of a BEC email. |

New Royal Ransomware Emerges in Multi-Million Dollar Attacks
(published: September 29, 2022)
AdvIntel and BleepingComputer researchers describe the Royal ransomware group. Several experienced ransomware actors formed this group in January 2022. It started with third-party encryptors such as BlackCat, switched to using its own custom Zeon ransomware, and, since the middle of September 2022, the Royal ransomware. Royal group utilizes targeted callback phishing attacks. Its phishing emails impersonating food delivery and software providers contained phone numbers to cancel the alleged subscription (after the alleged end of a free trial). If an employee calls the number, Royal uses social engineering to convince the victim to install a remote access tool, which is used to gain initial access to the corporate network.
Analyst Comment: Use services such as Anomali's Premium Digital Risk Protection to detect the abuse of your brands in typosquatting and phishing attacks. Organizations should include callback phishing attacks awareness into their anti-phishing training.

ZINC Weaponizing Open-Source Software
(published: September 29, 2022)
Microsoft researchers described recent developments in Lazarus Group (ZINC) campaigns that start from social engineering conversations on LinkedIn. Since June 2022, Lazarus was able to trojanize several open-source tools (KiTTY, muPDF/Subliminal Recording software installer, PuTTY, TightVNC, and Sumatra PDF Reader). When a target extracts the trojanized tool from the ISO file and installs it, Lazarus is able to deliver their custom malware such as EventHorizon and ZetaNile. In many cases, the final payload was not delivered unless the target manually established an SSH connection to an attacker-controlled IP address provided in the attached ReadMe.txt file.
Analyst Comment: All known indicators connected to this recent Lazarus Group campaign are available in the Anomali platform and customers are advised to block these on their infrastructure. Researchers should monitor for the additional User Execution step required for payload delivery. Defense contractors should be aware of advanced social engineering efforts abusing LinkedIn and other means of establishing trusted communication.

Microsoft Investigates Iranian Attacks Against the Albanian Government
(published: September 8, 2022)
Microsoft researchers discovered that groups working under Iran’s Ministry of Intelligence and Security (MOIS, tracked as OilRig) attacked the government of Albania. The attackers started with initial intrusion in May 2021, proceeded with mailbox exfiltrations between October 2021 and January 2022, organized controlled leaks, and culminated on July 15, 2022, with disruptive ransomware and wiper attacks. This attack is probably a response to the June 2021 Predatory Sparrow’s anti-Iranian cyber operations promoting the Mujahedin-e Khalq (MEK), an Iranian dissident group largely based in Albania.
Analyst Comment: MOIS attack on Albania uses messaging and targeting similar to the previous MEK-associated attack on Iran. It tells us that Iran has chosen to engage in a form of direct and proportional retaliation as it sees it. Still, the attack and its attribution caused Albania to cut diplomatic ties with Iran and expel the country's embassy staff. Organizations should implement multifactor authentication (MFA) for mailbox access and remote connectivity. Anomali platform users advised to block known OilRig network indicators.

Secureworks researchers detected a new campaign by China-sponsored group Mustang Panda (Bronze President). In June and July 2022, the group used spearphishing to deliver the PlugX malware to government officials in Europe, the Middle East, and South America. To bypass mail-scanning antiviruses, the archived email attachment had malware embedded eight levels deep in a sequence of hidden folders named with special characters.
Analyst Comment: Many advanced attacks start with basic techniques such as unwarranted email with malicious attachment that requires the user to open it and enable macros. It is important to teach your users basic online hygiene and phishing awareness.

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 |

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 |

2022-09-06 08:00:00 | Researcher Spotlight: How Asheer Malhotra looks for \'instant gratification\' in threat hunting (lien direct) | The India native has transitioned from a reverse-engineer hobbyist to a public speaker in just a few years By Jon Munshaw. Ninety percent of Asheer Malhotra's work will never see the light of day. But it's that 10 percent that keeps him motivated to keep looking for something new. The Talos Outreach researcher spends most of his days looking into potential new threats. Many times, that leads to dead ends of threats that have already been discovered and blocked or don't have any additional threads to pull on. But eventually, the “lightbulb goes off,” as he puts it, which indicates something is a new threat the wider public needs to know about. During his time at Talos, Malhotra has spent much of his time looking into cyber attacks and state-sponsored threat actors in Asia, like the Transparent Tribe group he's written about several times. “At some point, I say 'Hey, I don't think I've seen this before.' I start analyzing public disclosures, and slowly start gaining confidence and being able to craft a narrative around the motivations and tactics around a specific threat actor or malware campaign,” he said. In the case of Transparent Tribe, Malhotra's tracked their growth as a major player in the threat landscape in Asia, as they've added several remote access trojans to their arsenal, targeted high-profile government-adjacent entities in India and expanded their scope across the region. When he's not threat hunting, Malhotra also speaks to Cisco customers about the current state of cybersecurity in briefings and delivers presentations at conferences around the world (mainly virtually during the COVID-19 pandemic).  “I always try to find the latest and new stuff to talk about. … I've been honing my skills and trying to speak more confidently publicly, but the confidence is backed up with the right kind of knowledge and the threat intelligence, that's what helps me succeed,” he said. Malhotra is a native of India and spent most of his life there before coming to the U.S. for his master's degree at Mississippi State University. Mississippi was a far cry from everything else he had known up until that point, but he quickly adjusted. “That was the 'Deep South,'” he said. “So there was a culture shock, but the southern hospitality is such a real thing, and it felt very normal there.” Growing up, Malhotra always knew he wanted to work with computers, starting out as a teenager reverse-engineering exploits he'd see others talk about on the internet or just poking at smaller applications. His additional interest in politics and national security made it natural for him to combine the two and focus his research on state-sponsored actors. He enjoys continuing his research in the Indian subcontinent and sees many parallels between the state of security in India and the U.S. “Th |

LastPass Hackers Stole Source Code
(published: August 26, 2022)
In August 2022, an unidentified threat actor gained access to portions of the password management giant LastPass development environment. LastPass informed that it happened through a single compromised developer account and the attacker took portions of source code and some proprietary LastPass technical information. The company claims that this incident did not affect customer data or encrypted password vaults.
Analyst Comment: This incident doesn’t seem to have an immediate impact on LastPass users. Still, organizations relying on LastPass should raise the concern in their risk assessment since “white-box hacking” (when source code of the attacking system is known) is easier for threat actors. Organizations providing public-facing software should take maximum measures to block threat actors from their development environment and establish robust and transparent security protocols and practices with all third parties involved in their code development.

Mercury Leveraging Log4j 2 Vulnerabilities in Unpatched Systems to Target Israeli
(published: August 25, 2022)
Starting in July 2022, a new campaign by Iran-sponsored group Static Kitten (Mercury, MuddyWater) was detected targeting Israeli organizations. Microsoft researchers detected that this campaign was leveraging exploitation of Log4j 2 vulnerabilities (CVE-2021-45046 and CVE-2021-44228) in SysAid applications (IT management tools). For persistence Static Kitten was dropping webshells, creating local administrator accounts, stealing credentials, and adding their tools in the startup folders and autostart extensibility point (ASEP) registry keys. Overall the group was heavily using various open-source and built-in operating system tools: eHorus remote management software, Ligolo reverse tunneling tool, Mimikatz credential theft tool, PowerShell programs, RemCom remote service, Venom proxy tool, and Windows Management Instrumentation (WMI).
Analyst Comment: Network defenders should monitor for alerts related to web shell threats, suspicious RDP sessions, ASEP registry anomaly, and suspicious account creation. Similarly, SysAid users can monitor for webshells and abnormal processes related to SysAisServer instance. Even though Static Kitten was observed leveraging the Log4Shell vulnerabilities in the past (targeting VMware apps), most of their attacks still start with spearphishing, often from a compromised email account.

This war-induced fragility has exposed the weaknesses of how we feed ourselves globally. Ransomware cartels and other adversaries are well aware of this and are actively exploiting that fragility. For the past six years, Cisco Talos has been actively involved in assisting public and private institutions in Ukraine to defend themselves against state-sponsored actors. Our involvement stretches the gamut from commercial to critical infrastructure, to election security. Our presence has afforded us unique opportunities and observations about cybersecurity in a macro and micro way. Ukraine has been a frequent victim of state-sponsored cyber attacks aimed at critical infrastructures like power and transportation. Talos is proud to stand with our partners in Ukraine and help defend their critical networks and help users there maintain access to necessary services. Now that Russia has invaded Ukraine, those threats have escalated to kinetic attacks that are wreaking havoc on a critical element of our world: agriculture and our global food supply chain. Even worse is the implications this war will have for future cyber attacks, as fragility is considered a lucrative element in deciding victimology by threat actors like ransomware cartels. To truly grasp the implications of the war in Ukraine, we have to examine how vital Ukrainian agriculture feeds the world, the current state of affairs, and what this means for the global cybersecurity posture to protect agricultural assets. Where there is weakness, there is opportunityRansomware cartels and their affiliates are actively targeting the agricultural industry. Moreover, these actors have done their homework and are targeting agricultural companies during the two times of the year where they cannot suffer disruptions: planting and harvesting. Per the published FBI PIN Alert: “Cyber actors may perceive cooperatives as lucrative targets with a willingness to pay due to the time-sensitive role they play in agricultural production.” This is far from unusual for these adversaries - they are shrewd and calculating, and understand their victims' weaknesses and industries.

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.

SharpTongue Deploys Clever Mail-Stealing Browser Extension “SHARPEXT”
(published: July 28, 2022)
Volexity researchers discovered SharpExt, a new malicious browser app used by the North-Korea sponsored Velvet Chollima (Kimsuky, SharpTongue, Thallium) group. SharpExt inspects and exfiltrates data from a victim's webmail (AOL or Gmail) account as they browse it. Velvet Chollima continues to add new features to the app, the latest known version (3.0) supports three browsers: Microsoft Edge, Google Chrome, and Whale, the latter almost exclusively used in South Korea. Following the initial compromise, Velvet Chollima deploy SharpExt and to avoid warning the victim they manually exfiltrate settings files to change the settings and generate a valid "super_mac" security check value. They also hide the newly opened DevTools window and any other warning windows such as a warning regarding extensions running in developer mode.
Analyst Comment: Velvet Chollima is known for its tactic of deploying malicious browser extensions, but in the past it was concentrating on stealing credentials instead of emails. The group continues aggressive cyberespionage campaigns exfiltrating military and industrial technologies from Europe, South Korea, and the US. Network defenders should monitor for suspicious instances of PowerShell execution, as well as for traffic to and from known Velvet Chollima infrastructure (available in Anomali Match).

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 | |

Update: The Phish Goes On - 5 Million Stolen Credentials and Counting
(published: June 16, 2022)
PIXM researchers describe an ongoing, large-scale Facebook phishing campaign. Its primary targets are Facebook Messenger mobile users and an estimated five million users lost their login credentials. The campaign evades Facebook anti-phishing protection by redirecting to a new page at a legitimate service such as amaze.co, famous.co, funnel-preview.com, or glitch.me. In June 2022, the campaign also employed the tactic of displaying legitimate shopping cart content at the final page for about two seconds before displaying the phishing content. The campaign is attributed to Colombian actor BenderCrack (Hackerasueldo) who monetizes displaying affiliate ads.
Analyst Comment: Users should check what domain is asking for login credentials before providing those. Organizations can consider monitoring their employees using Facebook as a Single Sign-On (SSO) Provider.

COBALT MIRAGE Conducts Ransomware Operations in U.S.
(published: May 12, 2022)
Secureworks researchers describe campaigns by Iran-sponsored group Cobalt Mirage. These actors are likely part of a larger group, Charming Kitten (Phosphorus, APT35, Cobalt Illusion). In 2022, Cobalt Mirage deployed BitLocker ransomware on a US charity systems, and exfiltrated data from a US local government network. Their ransomware operations appear to be a low-scale, hands-on approach with rare tactics such as sending a ransom note to a local printer. The group utilized its own custom binaries including a Fast Reverse Proxy client (FRPC) written in Go. It also relied on mass scanning for known vulnerabilities (ProxyShell, Log4Shell) and using commodity tools for encryption, internal scanning, and lateral movement.
Analyst Comment: However small your government or NGO organization is, it still needs protection from advanced cyber actors. Keep your system updated, and employ mitigation strategies when updates for critical vulnerabilities are not available.

The short answer is financial gain. Attackers know bringing down VoIP providers that service a large number of customers causes a lot of pain and therefore is ripe for extortion.Cyber attackers launched three worldwide distributed denial-of-service (DDoS) extortion attack campaigns in 2021 – a startling new achievement carried out by a REvil copycat, Lazarus Bear Armada (LBA), and Fancy Lazarus.

A Lookback Under the TA410 Umbrella: Its Cyberespionage TTPs and Activity
(published: April 28, 2022)
ESET researchers found three different teams under China-sponsored umbrella cyberespionage group TA410, which is loosely linked to Stone Panda (APT10, Chinese Ministry of State Security). ESET named these teams FlowingFrog, JollyFrog, and LookingFrog. FlowingFrog uses the Royal Road RTF weaponizer described by Anomali in 2019. Infection has two stages: the Tendyron implant followed by a very complex FlowCloud backdoor. JollyFrog uses generic malware such as PlugX and QuasarRAT. LookingFrog’s infection stages feature the X4 backdoor followed by the LookBack backdoor. Besides using different backdoors and exiting from IP addresses located in three different districts, the three teams use similar tools and similar tactics, techniques, and procedures (TTPs).
Analyst Comment: Organizations should keep their web-facing applications such as Microsoft Exchange or SharePoint secured and updated. Educate your employees on handling suspected spearphishing attempts. Defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) is the best way to ensure safety from APTs, including a focus on both network and host-based security. Prevention and detection capabilities should also be in place.

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.
