Threat actors are targeting the education, government and business services sectors with a remote access trojan called **NetSupport RAT**.

"The delivery mechanisms for the NetSupport RAT encompass fraudulent updates, drive-by downloads, utilization of malware loaders (such as GHOSTPULSE), and various forms of phishing campaigns," VMware Carbon Black researchers said in a report shared with The Hacker News.

The cybersecurity firm said it detected no less than 15 new infections related to NetSupport RAT in the last few weeks.

While NetSupport Manager started off as a legitimate remote administration tool for technical assistance and support, malicious actors have misappropriated the tool to their own advantage, using it as a beachhead for subsequent attacks.

NetSupport RAT is typically downloaded onto a victim's computer via deceptive websites and fake browser updates.

In August 2022, Sucuri detailed a campaign in which compromised WordPress sites were being used to display fraudulent Cloudflare DDoS protection pages that led to the distribution of NetSupport RAT.

The use of bogus web browser updates is a tactic often associated with the deployment of a JavaScript-based downloader malware known as SocGholish (aka FakeUpdates), which has also been observed propagating a loader malware codenamed BLISTER.

The Javascript payload subsequently invokes PowerShell to connect to a remote server and retrieve a ZIP archive file containing NetSupport RAT that, upon installation, beacons out to a command-and-control (C2) server.

"Once installed on a victim's device, NetSupport is able to monitor behavior, transfer files, manipulate computer settings, and move to other devices within the network," the researchers said.

Czech Republic Police Expose 'Fake Bankers' Gang in $8.7 Million Vishing Operation.
This is a post from HackRead.com Read the original post: Multimillion-Dollar Vishing Scam Busted: Czech-Ukrainian Gang Arrested

Europol Warns of Growing Vishing Trend as Criminals Exploit Phone Calls for Massive Financial Gains

Ukrainian and Czech police under the supervision of Europol have dismantled a criminal gang that stole millions of dollars from bank customers in Czechia through vishing scams. According to Europol’s press release, the police also arrested ten suspects (aged 18-29) in connection with the multimillion-dollar fraud ring.

A joint investigation was initiated by Europol that led to the arrest of four individuals in Czechia and six in Ukraine in April 2023. Those arrested from Ukraine were later extradited to Czechia.

During the crackdown, investigators seized SIM cards, mobile phones, and computer equipment from the suspects’ vehicles, call centers, residences, and offices located in Czechia (Domazlice, Rokycany, and Plzen) and Ukraine (Dnipropetrovsk). Some of the suspects had a history of drug offences, violent crimes, and document forgery.

The criminal organization, based in Ukraine, conducted vishing attacks against Czech victims. They operated from call centers in Ukraine and called bank customers using spoofed phone numbers, posing as bank security officers. This scamming method is called vishing (created by combining voice and phishing).

The targets were told that their bank account was hacked and lured into revealing their banking data, such as credit card numbers, login credentials, and other details. Scammers also made phone calls pretending to be a police official to confirm the hacking.

After gaining trust, the scammers persuaded their victims to transfer funds from their “compromised” bank accounts to “safe” bank accounts, which the scammers owned. Through these scams, the fraudsters made approximately $8.7 million (€8 million) from victims in Czechia alone.

The Czech Republic police uncovered this scam. In November 2021, they contacted Eurojust to launch an investigation. Europol then formed a joint investigation team in June 2022, comprising Europol’s European Cybercrime Centre (EC3) officials and the Czech and Ukrainian investigators. The agency organized five meetings to facilitate judicial cooperation between the authorities.

The police called the gang’s activities one of the **“most extensive series of frauds committed through fake bankers.”** Currently, Europol is conducting analytical work and providing digital forensic support for the confiscated equipment.

Image via Czech Republic police

Vishing fraud has become more widespread and popular lately. It usually involves someone pretending to be from a reputable organization, institution, or government agency and deceiving people into disclosing confidential, personal data.

The severity of vishing scams is highlighted by the September 2023 incident when the notorious ALPHV (BlackCat) ransomware gang exploited vishing to deceive an MGM Resorts employee, enabling them to breach the company’s security and compromise its network.

To protect yourself from such scams, always be cautious of unsolicited phone calls, note the caller’s phone number, and tell them you will call back and quickly verify their identity by calling the organization.

Don’t believe any caller if they have basic information about you because it could be taken from social media. Lastly, keep your credit/ debit card PIN or online banking password private because bank representatives would never ask for this information.

The Ddostf Botnet was initially identified in 2016.
This is a post from HackRead.com Read the original post: Ddostf Botnet Resurfaces in DDoS Attacks Against MySQL and Docker Hosts

Researchers claim that the Chinese Ddostf botnet is specifically designed for launching DDoS attacks and that the threat actors are operating a DDoS-for-hire service.

AhnLab Security Emergency Response Center (ASEC) researchers have shared alarming **details** of a new campaign targeting MySQL servers and Docker hosts with DDoS malware.

AhnLab noted that attacks targeting MySQL servers on Windows systems have increased sharply, and vulnerable servers are infected with the Chinese botnet Ddostf, **discovered** in 2016.

Researchers claim that this malware is specifically designed for launching DDoS attacks and that the threat actor is operating a **DDoS-for-hire service**.

According to the AESC blog post, threat actors scan for exploitable MySQL servers. After compromising the servers, threat actors install the Ddostf DDoS botnet to launch distributed denial-of-service (DDoS) attacks against other servers.

**MySQL servers** are a common target in such campaigns because of their widespread use in Windows and Linux environments. Although MS-SQL is a preferred database service for Windows users, MySQL servers are also commonly used on Windows, which makes the systems running them a prime target for cybercriminals.

Based on data from AhnLab’s Smart Defense (ASD) logs, most malware targeting vulnerable MySQL servers were **Gh0st RAT** variants, but instances of **AsyncRAT** were also observed and recently, there’s been an uptick in the use of the Ddostf botnet.

Ddostf is a powerful malware that copies itself with a random name in the %SystemRoot% directory and registers as a service before decrypting the encrypted C2 server URL string to connect to the attackers’ server. It can collect system data and transfer it to the C2 server. Then it waits for specific commands (e.g., SYN, UDP, and HTTP GET/POST floods) to launch the **DDoS attacks**.

The botnet is unique because it can connect to a new address from the C2 server and execute commands there for a limited time. This helps the Ddostf botnet operator to infect multiple systems and sell DDoS attacks as a service. Ddostf can target Linux and Windows systems because of supports both ELF and PE formats and can achieve persistence. 

Attackers first scan for publicly accessible systems using port 3306/TCP and after accessing the server (those with known vulnerabilities or weak credentials), they use brute-force or dictionary attacks on the system.

If the system has signs of poor credential management, attackers can gain access to administrator account credentials. If the system runs an **unpatched version with vulnerabilities**, attackers can exploit them to execute commands without needing these processes. Unlike MS-SQL, which entails direct OS command execution methods, MySQL relies on UDFs (User-Defined Functions) that can allow threat actors to execute commands.

They can also install malicious UDF DLLS on infected MySQL servers and execute commands. Like CLR Stored Procedure WebShell work, these DLLs can provide threat actors complete control of the infected system. In the case of the Ddostf DDoS bot, attackers use the UDF malware as a tool to install it on poorly managed MySQL servers.

Database servers get frequently targeted because of poorly managed account credentials. Administrators must use strong passwords apart from applying the latest patches to protect their servers. Firewalls can be used to restrict access to external actors, and a DDoS mitigation service can help protect against **large-scale attacks**.
