After the device vulnerability (CVE-2023-28771) patched by Zyxel on April 25 was released in May, security experts warned that the Mirai botnet began to threaten unpatched Zyxel devices to launch attacks. The ShadowServer Foundation, a security nonprofit, has detected that multiple Zhaoqin devices have been used to launch attacks. Since the abused PoC program has been made public, the foundation also expects the attacks to increase further. Zyxel patched the major vulnerability CVE-2023-28771 in firewall and VPN equipment products in April , and urged users to install the new firmware as soon as possible. This vulnerability originates from the IKE packet decryption component in the firmware, which may allow unauthorized attackers to send malicious packets to remotely execute OS commands. It is a major vulnerability with a risk value of 9.8. Last week, the information security company Rapid7 also warned that at least 40,000 firewall devices have been exposed because they have not been updated, and they believe that there will be exploit attacks. Since May 26, more than 700 decoy systems set up by the security nonprofit The ShadowServer Foundation have detected about 3,773 attacks. According to the statistics of the Foundation , the users of Zhaoqin’s firewall and VPN products are the most in France (13,800 units), Italy (13,100 units), the United States (9,300 units), and Switzerland (7,800 units). In addition, they also detect Multiple Zhaoqin devices have been used to launch attacks . Since the abused PoC program has been made public, the foundation also expects the attacks to increase further .

State Technical Service JSC reports that during the monitoring of the Kazakhstani segment of the Internet, 17 IP addresses were found that are presumably subject to critical vulnerabilities with identifiers CVE-2022-24816 and CVE-2023-25157. The detected IP addresses belong to large companies in the quasi-public sector of Kazakhstan. GeoServer is used in various industries such as geology, ecology, geodesy, agriculture, urban management, etc., where spatial data is an important component for making strategic decisions. The National Computer Incident Response Service (KZ-CERT) sent notifications to owners of IP addresses and telecom operators recommending the need to immediately apply updates to avoid possible risks and threats to information security. Failure to address vulnerabilities in a timely manner can lead to the compromise of sensitive data and further attacks on the network, including the introduction of malicious software into other systems, which will compromise the security of the entire network infrastructure. The Shadowserver Foundation (an information security organization that sends daily online reports to subscribers and cooperates with law enforcement agencies around the world in investigating cybercrime) published information about vulnerabilities in the GeoServer software. We recommend that all companies pay attention to updates of systems and software used in the infrastructure,” KZ-Cert noted.

IT teams operating Microsoft Exchange servers are very slow at patching their endpoints, resulting in thousands of devices still being vulnerable to some high-severity flaws. This is according to a new report on CyberNews, which claims more than 85,000 servers are still exposed to multiple remote code execution (RCE) vulnerabilities, namely CVE-2023-21529, CVE-2023-21706, and CVE-2023-21707. The report has described the flaws as “extremely dangerous” due to the fact that they can allow the threat actors to run malicious code and compromise people’s inboxes and email messages sitting on the servers. The flaws were discovered in mid-February 2023, with Microsoft being quick to release a patch to address the issue. However, many IT teams are yet to apply these patches, they’re saying. In fact, as per Shadowserver Foundation data, the number of vulnerable servers in February was 87,000, meaning the vast majority of IT teams basically disregarded this security threat and simply decided not to apply the fix.

A four-count indictment was unsealed today in the United States District Court for the Eastern District of New York charging Denis Gennadievich Kulkov with access device fraud, computer intrusion and money laundering in connection with his operation of Try2Check, the primary service offering “card-checking” to cybercriminals in the stolen credit card trade.  The Try2Check platform catered to cybercriminals who purchased and sold stolen credit card numbers in bulk on the internet, offering criminals the ability to quickly determine what percentage of the cards were valid and active.  As such, Try2Check was a primary enabler of the trade in stolen credit card information, processing at minimum tens of millions of card numbers every year.  Today, the U.S. government worked with partners in Germany and Austria to take offline Try2Check’s websites, thus dismantling the defendant’s criminal network.  Along with the indictment and global website domain takedown, the State Department has announced a $10 million reward for information leading to the capture of Kulkov, who resides in Russia. Try2Check ran tens of millions of credit card checks per year and supported the operations of major card shops that made hundreds of millions in bitcoin in profits.  Over a nine-month period in 2018, the site performed at least 16 million checks, and over a 13-month period beginning in September 2021, the site performed at least 17 million checks. Through the illegal operation of his websites, the defendant made at least $18 million in bitcoin (as well as an unknown amount through other payment systems), which he used to purchase a Ferrari, among other luxury items.  In coordination with the unsealing of the charging documents in this case, Try2Check’s websites were taken offline and the State Department issued a $10 million reward for information leading to the defendant’s capture.  If convicted, Kulkov faces 20 years’ imprisonment. The charges in the indictment are allegations, and the defendant is presumed innocent unless and until proven guilty. The Office extends its appreciation to the German Federal Criminal Police Office (BKA), the German Federal Office for Information Security (BSI), the Austrian Criminal Intelligence Service – Cybercrime Competence Center (C4), and the French Central Directorate of the Judicial Police (DCPJ) and the governments of Austria, Germany and France for their assistance on this case, as well as to the Shadowserver Foundation for crucial technical assistance in addressing 

Interpol’s African Bureau of Cybercrime Operations report ranks Morocco as the African country most affected by Banking Trojans and Stealers. It is also the second most affected country by Ransomware on the continent. The African Cybercrime Operations Bureau of the International Criminal Police Organization (Interpol) recently unveiled its Africa Cyber Threat Assessment Report for the year 2022. A document that provides an overview of cyber threat trends in the African region. It shows that Morocco is the African country most affected by banking Trojans and Stealers, according to data from Trend Micro, a world leader in enterprise cloud security solutions, XDR and cybersecurity platform. The Interpol report even mentions 18,827 detections in the kingdom, which puts it ahead of South Africa (6,560 malware detections), Nigeria (5,366), Cameroon (1,462) and Algeria ( 691).  Banking Trojans and Stealers can be installed manually or remotely using techniques such as emails containing malicious links or attachments.  The report also revealed that the most prevalent banking Trojans and Stealers are Zbot and Fareit. The former accounts for 67.67% of all detections in the region, while the latter accounts for 15.39%.  The report also ranks Morocco in second place when it comes to Ransomware. Quoting Shadowserver, a non-profit security organization that collects and analyzes data on malicious activity on the Internet. South Africa is the country most targeted by these attacks. The country accounts for 42% of all detected attacks. It is followed by Morocco where 8% of the attacks took place, Botswana and Egypt (6%) as well as Tanzania and Kenya (4%). The kingdom is also cited for “online scams and extortion”. 

After worldwide scans, security researchers have discovered over 400,000 potentially vulnerable Windows systems. Security patches are available.

Windows admins should quickly take care of a ” critical ” vulnerability in the Microsoft Message Queuing Service (MSMQ) in Windows and Windows Server. If attacks are successful, attackers could execute malicious code and completely compromise systems. The vulnerability (CVE-2023-21554) was closed on Patchday in April . As a prerequisite for attacks, the MSMQ server must be active, which is not the case by default. However, the service is often activated in the course of Exchange installations, so the gap should not be underestimated. To check if systems are vulnerable, admins should check if the “Message Queuing” service is running and listening on TCP port 1801. According to a warning from Microsoft, Windows 10, 11 and many Windows server versions such as 20H2 are affected. Message Queuing is a messaging infrastructure and development platform. Message queuing applications can use this to communicate with PCs that may be offline. The service is designed to guarantee message delivery. Checkpoint security researchers discovered the vulnerability . According to them, attackers would only have to send their exploit code to TCP port 1801 of MSMQ servers to trigger an attack. Patch now! According to scans by Shadowsever, the MSMQ service is publicly available on over 400,000 Windows systems worldwide. If these systems are not yet patched, attackers could strike. The majority of these can be found in Hong Kong with 160,000 instances. In the US, there are around 57,000. Almost 8,000 systems are publicly accessible in Germany.

Check Point Research recently discovered three vulnerabilities in the Microsoft Message Queuing service, a service that enables asynchronous communication between applications (such as systems that are sometimes offline). While MSMQ is not enabled by default and the bugs have been fixed since last Patch Day, hundreds of thousands of systems still appear to be vulnerable. The bugs have been assigned the codes CVE-2023-21554 , CVE-2023-21769 , and CVE-2023-28302 , with a score of 9.8 and 7.5 points out of 10 twice, respectively. The former is called QueueJumper and is categorized as critical given its high rating. This is because attackers can use modified MSMQ packets to execute malicious code on MSMQ-enabled systems. CPR recommends applying appropriate security updates as soon as possible. If this is not possible, system administrators should verify that the Message Queuing service is being used and that TCP port 1801 is open. Check Point has determined that this is the case for more than 360,000 systems. According to Shadowserver, there are no less than 403,000 vulnerable configurations, the vast majority of which are based in Hong Kong, South Korea and the US.

One of the things we do at VulnCheck is n-day analysis. That can include analysis of well-known, deeply researched, and widely exploited vulnerabilities. When we tackle that type of issue, we aim to learn something new, novel, or, at the very least, interesting. We recently took that approach analyzing CVE-2022-1388. CVE-2022-1388 is an authentication bypass vulnerability affecting F5 Big-IP products. When CVE-2022-1388 was disclosed in May 2022, there were only a few thousand internet-facing affected systems. But there was no stopping the infosec hype train. Multiple research organizations published redacted proof of concepts, Kevin Beaumont was tweeting about honeypot exploitation, randoms were dropping exploit screenshots, and reporters were mistaking jokes about an inside job for reality. Eventually, most of the speculation and fear-mongering were put to bed by an excellent deep-dive analysis from Horizon3.ai. When all the hype died down, the vulnerability was quite well-known. It’s been featured in research write-ups. There’s a Metasploit module, and Greynoise tag. Shadow Server identifies the vulnerability in their honeypot network. It was even named one of the [top vulnerabilities in 2022, and added to the CISA KEV Catalog. What more could be said about this vulnerability? Well, if you don’t look, you’ll never know.
