Cyber Attacks

CoralRaider Hackers Steal Data

XClient stealer and RotBot are two attack tools that Vietnamese threat actor CoralRaider uses to steal financial data, login credentials, and social media information from victims in Asian and Southeast Asian countries.

Since 2023, the group has been operational with complex approaches where they would integrate Vietnamese vocabularies into their payloads as a sort of hard coding.

The most recent campaign by this threat group involves using Windows shortcut files to distribute malware targeting South Korean, Bangladeshi, and Chinese nationals. This is a significant threat to individuals and businesses in the region.

Chinese Hackers Using AI Tools To Influence Upcoming Elections

The report concerns how Chinese hackers could use AI to influence the elections. While no instances are specifically mentioned in the report, it cautions against this cyber risk. 

Not only that even AI can be used to generate deepfake videos, control social media sites and undertake highly developed cyber offences which makes it a very powerful tool to influence the elections. 

Moreover, the report stresses on increasing cybersecurity defenses against such threats including improvements in detection and response capabilities. 

While it highlights the need of remaining alert and proactive towards changing cyber risks especially in line with elections and politics at large.

Threat Actors Deliver Malware Via YouTube Video

The report highlights a recent malware campaign in which Vidar, StealC, and Lumma Stealer information-stealing malware are disseminated via YouTube videos by hackers. 

These videos that pretend to be guides for getting free software or game upgrades have links to cracked video games and pirated software. These programs then compromise the users when they are executed.

Younger users are targeted by this campaign who trust popular computer games and credibility of YouTube. The use of bots is also referred to in the report as a way of boosting video’s authenticity, as well as distributing Lumma Stealer through Discord servers under the guise of game cheats.

AGENT TESLA Malware Targets Chrome & Firefox Login Credentials

The Agent Tesla malware went for American and Australian entities through the use of phishing emails that had fake purchase orders to make the victims open malicious links. 

After clicking, there was a download of an obfuscated Agent Tesla sample protected by Cassandra Protector which would then steal keystrokes and login credentials. The investigation found two culprits, Bignosa who was the main threat, and Gods who used numerous servers for RDP connections, and a large email database for their malware campaigns. 

This campaign required several steps of preparation before disseminating spam with malicious content. This is highly adaptable malware that can exploit different attack vectors such as email attachments, malicious URLs, document-based intrusions among others making it a big threat to organizations. 

To stay safe from threats like Email Tracking, Blocking, Modifying, Phishing, Account Take Over, Business Email Compromise Malware & Ransomware etc., it is advisable to implement AI-Powered Email security solutions.

Targus Hacked

Recently, the Targus company became a victim of cyberattack. This is among other rising cases of cyber threats where in the last year alone, the incidence rates of malicious emails slipping through Secure Email Gateways (SEGs) has doubled.

Also, an Ex-Google engineer Linwei Ding was arrested separately for stealing trade secrets most specifically those on artificial intelligence (AI).

Concerning data privacy also, the Italian Data Protection Authority (DPA) has begun investigating OpenAI, the US tech company which recently unveiled a state-of-the-art AI model named ‘Sora.’

Still though, SolarWinds cyberattack that targeted this same US think tank three times and succeeded remains a big concern as analysts believe that about 18000 customers were pushed out with this attack. They say it was done by aligning clients in these sectors to develop a ransomware-as-a-service opportunity.

Traditional law enforcement tools will be used by the Department of Justice (DOJ) in targeting illicit crypto operations to bring down ransomware operators and threat actors.

New Qakbot DLL

The Qakbot botnet, which was taken down in 2023 during Operation Duck Hunt, has re-emerged with an altered DLL that utilizes the srtasks.exe procedure for persistence to ensure its survival during machine restarts.

Qakbot is still propagated through phishing campaigns and often uses IRS-themed email to target only a small number of hospitality industry users. The malware employs anti-analysis techniques, hides its components from detection by using a dropper and malicious DLL files, and manipulates Windows processes so that it can persist on the system.

According to recent findings from Morphisec Threat Labs’ cyber security analysts, hackers are currently carrying out Steganography malware hiding technique in PNG files. This method escapes detection by security systems thereby allowing malware execution in memory.

Threat Analysis

Microsoft Two-Step Phishing Campaign

The Microsoft Two-Step Phishing Campaign targets LinkedIn users by sending them messages with a malicious link disguised as a legitimate OneDrive document link. 

What the attackers do is that they make the victims to click on a URL which will take them to the genuine page of OneDrive where there exists a Word document that contains malware and then embeds another URL in it so that the victims are directed through fake Cloudflare verification prompt into phishing webpages designed to steal Microsoft 365 credentials. 

This campaign highlights how social media platforms like LinkedIn are increasingly becoming weak points due to publicly accessible information about their users, which can be used for phishing. 

As in this case, threat actors were able to compromise accounts with MFA enabled because they can also bypass multifactor authentication (MFA) protection, as seen in a recent Microsoft 365 phishing campaign affecting over one hundred firms.

Vedalia APT Group Exploits Oversized LNK Files

Konni or “The Vedalia APT Group” has come up with a new way to install malware, they have been using oversized LNK files indicating some evolution in their modes of operation. The intention of this method is to go past the conventional security measures and affect targeted systems.

These LNK files have double extensions that effectively hide the malicious .lnk extension as well as make it more difficult for security software and analysts to identify the malwares commands lines embedded in them by employing excessive use of white spaces.

LNK files contain embedded command line script designed to search for and execute PowerShell commands. PowerShell’s legitimate system functions enable it to locate, deploy and unfold the hidden malicious files within.

This campaign highlights the changing landscape of cyber threats and reinforces the message that organizations and individuals need to maintain alertness, update their security solutions, and equip themselves with knowledge about these threats.

TA547 Hackers Launching AI-Powered Cyber Attacks

Midnight Blizzard Email Hack Threatens Federal Agencies

In January 2024 it emerged that Microsoft had suffered a hack on its corporate email network, which can be traced to the Russian state-sponsored group Midnight Blizzard.

The group hacked into an inactive test account and used it to penetrate some of Microsoft’s official e-mail addresses, including those belonging to senior management officials as well as their colleagues in cybersecurity, law, and other sectors. 

They took away with them some emails together with attached documents for attempting further intrusions into customer systems. 

The hackers launched a password spray attack – a technique where they tried one password against multiple accounts – but there is no evidence that they accessed customer data, production systems, or proprietary source code. 

The incident has raised concerns about national security implications, especially for federal organizations hence the issuance of an emergency directive from CISA. Microsoft has attempted to reduce the risk by alerting all federal agencies affected by these breaches and imposing distinct guidelines aimed at enhancing security in their systems.

Hackers Weaponize Suspended Domains

In an ongoing phishing campaign that has been aimed at Latin America, threat actors have resorted to weaponizing suspended domains. They managed to do this by using free and temporary email addresses with the domain “” as well as a spoofed User-Agent field. This was done in order to make recipients of such emails wrongly download malware. 

This implies a potentially malicious URL leading to a non-functional page that redirects victims to a two-step verification process containing a malicious RAR archive carrying a PowerShell script designed for collecting information from the victim’s machine.

The validity of URLs used in this phishing attack is questionable, and it stresses how dangerous dealing with suspicious emails or their attachments can be.

Fortinet Vulnerability Exploited

A Fortinet Forticlient EMS vulnerability (CVE-2023-48788) is a security hole that threat actors have exploited to plant unsanctioned RMM and PowerShell backdoor on machines.

The critical vulnerability was fixed by Fortinet in March 2024. The exploit consisted of an external IP being connected to the FCMdaemon process resulting in tool deployment which was malicious.

It only took a few minutes for the attackers to install the backdoors, highlighting how important it is to patch the vulnerabilities immediately. To avoid any possible attack users should upgrade from their current versions of Forticlient EMS that are affected.

Hackers Using Malware-Driven Scanning Attacks
