Golang | Breaking Cybersecurity News | The Hacker News

Threat hunters are calling attention to a new highly-targeted phishing campaign that singled out "fewer than five" entities in the United Arab Emirates (U.A.E.) to deliver a previously undocumented Golang backdoor dubbed Sosano. The malicious activity was specifically directed against aviation and satellite communications organizations, according to Proofpoint, which detected it in late October 2024. The enterprise security firm is tracking the emerging cluster under the moniker UNK_CraftyCamel . A noteworthy aspect of the attack chain is the fact that the adversary took advantage of its access to a compromised email account belonging to the Indian electronics company INDIC Electronics to send phishing messages. The entity is said to have been in a trusted business relationship with all the targets, with the lures tailored to each of them. "UNK_CraftyCamel leveraged a compromised Indian electronics company to target fewer than five organizations in the United Arab E...

Cybersecurity researchers have shed light on a new Golang-based backdoor that uses Telegram as a mechanism for command-and-control (C2) communications. Netskope Threat Labs, which detailed the functions of the malware, described it as possibly of Russian origin. "The malware is compiled in Golang and once executed it acts like a backdoor," security researcher Leandro Fróes said in an analysis published last week. "Although the malware seems to still be under development it is completely functional." Once launched, the backdoor is designed to check if it's running under a specific location and using a specific name – "C:\Windows\Temp\svchost.exe" – and if not, it reads its own contents, writes them to that location, and creates a new process to launch the copied version and terminate itself. A notable aspect of the malware is that it uses an open-source library that offers Golang bindings for the Telegram Bot API for C2 purposes. This involves...

Most microsegmentation projects fail before they even get off the ground—too complex, too slow, too disruptive. But Andelyn Biosciences proved it doesn't have to be that way.  Microsegmentation: The Missing Piece in Zero Trust Security   Security teams today are under constant pressure to defend against increasingly sophisticated cyber threats. Perimeter-based defenses alone can no longer provide sufficient protection as attackers shift their focus to lateral movement within enterprise networks. With over 70% of successful breaches involving attackers moving laterally, organizations are rethinking how they secure internal traffic.  Microsegmentation has emerged as a key strategy in achieving Zero Trust security by restricting access to critical assets based on identity rather than network location. However, traditional microsegmentation approaches—often involving VLAN reconfigurations, agent deployments, or complex firewall rules—tend to be slow, operationally disrupt...

A previously undocumented threat actor known as Silent Lynx has been linked to cyber attacks targeting various entities in Kyrgyzstan and Turkmenistan. "This threat group has previously targeted entities around Eastern Europe and Central Asian government think tanks involved in economic decision making and banking sector," Seqrite Labs researcher Subhajeet Singha said in a technical report published late last month. Targets of the hacking group's attacks include embassies, lawyers, government-backed banks, and think tanks. The activity has been attributed to a Kazakhstan-origin threat actor with a medium level of confidence. The infections commence with a spear-phishing email containing a RAR archive attachment that ultimately acts as a delivery vehicle for malicious payloads responsible for granting remote access to the compromised hosts. The first of the two campaigns, detected by the cybersecurity company on December 27, 2024, leverages the RAR archive to launc...

The Chinese-speaking threat actor known as Earth Lusca has been observed using a new backdoor dubbed KTLVdoor as part of a cyber attack targeting an unnamed trading company based in China. The previously unreported malware is written in Golang, and thus is a cross-platform weapon capable of targeting both Microsoft Windows and Linux systems. "KTLVdoor is a highly obfuscated malware that masquerades as different system utilities, allowing attackers to carry out a variety of tasks including file manipulation, command execution, and remote port scanning," Trend Micro researchers Cedric Pernet and Jaromir Horejsi said in an analysis published Wednesday. Some of the tools KTLVdoor impersonates include sshd, Java, SQLite, bash, and edr-agent, among others, with the malware distributed in the form of dynamic-link library (.dll) or a shared object (.so). Perhaps the most unusual aspect of the activity cluster is the discovery of more than 50 command-and-control (C&C) s...

Cybersecurity researchers have uncovered a new malware campaign that targets publicly exposed Docket API endpoints with the aim of delivering cryptocurrency miners and other payloads. Included among the tools deployed is a remote access tool that's capable of downloading and executing more malicious programs as well as a utility to propagate the malware via SSH, cloud analytics platform Datadog said in a report published last week. Analysis of the campaign has uncovered tactical overlaps with a previous activity dubbed Spinning YARN , which was observed targeting misconfigured Apache Hadoop YARN, Docker, Atlassian Confluence, and Redis services for cryptojacking purposes. The attack commences with the threat actors zeroing in on Docker servers with exposed ports (port number 2375 ) to initiate a series of steps, starting with reconnaissance and privilege escalation before proceeding to the exploitation phase. Payloads are retrieved from adversary-controlled infrastructure by...

Cybersecurity researchers have identified a malicious Python package that purports to be an offshoot of the  popular requests library  and has been found concealing a Golang-version of the Sliver command-and-control (C2) framework within a PNG image of the project's logo.  The package employing this steganographic trickery is  requests-darwin-lite , which has been downloaded 417 times prior to it being taken down from the Python Package Index (PyPI) registry. Requests-darwin-lite "appeared to be a fork of the ever-popular requests package with a few key differences, most notably the inclusion of a malicious Go binary packed into a large version of the actual requests side-bar PNG logo," software supply chain security firm Phylum  said . The changes have been introduced in the package's setup.py file, which has been configured to decode and execute a Base64-encoded command to gather the system's Universally Unique Identifier ( UUID ), but...

The North Korean threat actor tracked as Kimsuky has been observed deploying a previously undocumented Golang-based malware dubbed  Durian  as part of highly-targeted cyber attacks aimed at two South Korean cryptocurrency firms. "Durian boasts comprehensive backdoor functionality, enabling the execution of delivered commands, additional file downloads, and exfiltration of files," Kaspersky  said  in its APT trends report for Q1 2024. The attacks, which occurred in August and November 2023, entailed the use of legitimate software exclusive to South Korea as an infection pathway, although the precise mechanism used to manipulate the program is currently unclear. What's known is that the software establishes a connection to the attacker's server, leading to the retrieval of a malicious payload that kicks off the infection sequence. The first-stage serves as an installer for additional malware and a means to establish persistence on the host. It also paves the way f...

Government entities in the Middle East have been targeted as part of a previously undocumented campaign to deliver a new backdoor dubbed CR4T. Russian cybersecurity company Kaspersky said it discovered the activity in February 2024, with evidence suggesting that it may have been active since at least a year prior. The campaign has been codenamed  DuneQuixote . "The group behind the campaign took steps to prevent collection and analysis of its implants and implemented practical and well-designed evasion methods both in network communications and in the malware code," Kaspersky  said . The starting point of the attack is a dropper, which comes in two variants -- a regular dropper that's either implemented as an executable or a DLL file and a tampered installer file for a legitimate tool named  Total Commander . Regardless of the method used, the primary function of the dropper is to extract an embed...

A new phishing campaign has set its eyes on the Latin American region to deliver malicious payloads to Windows systems. "The phishing email contained a ZIP file attachment that when extracted reveals an HTML file that leads to a malicious file download posing as an invoice," Trustwave SpiderLabs researcher Karla Agregado  said . The email message, the company said, originates from an email address format that uses the domain "temporary[.]link" and has Roundcube Webmail listed as the User-Agent string. The HTML file points containing a link ("facturasmex[.]cloud") that displays an error message saying "this account has been suspended," but when visited from an IP address geolocated to Mexico, loads a CAPTCHA verification page that uses Cloudflare Turnstile. This step paves the way for a redirect to another domain from where a malicious RAR file is downloaded. The RAR archive comes with a PowerShell script that gathers system metadata as well...

Several malicious Android apps that turn mobile devices running the operating system into residential proxies (RESIPs) for other threat actors have been observed on the Google Play Store. The findings come from HUMAN's Satori Threat Intelligence team, which said the cluster of VPN apps came fitted with a Golang library that transformed the user's device into a proxy node without their knowledge. The operation has been codenamed  PROXYLIB  by the company. The 29 apps in question have since been removed by Google. Residential proxies are a network of proxy servers sourced from real IP addresses provided by internet service providers (ISPs), helping users hide their actual IP addresses by routing their internet traffic through an intermediary server. The anonymity benefits aside, they are ripe for abuse by threat actors to not only obfuscate their origins, but also to conduct a wide range of attacks. "When a threat actor uses a residential proxy, the traffic from these...

Chinese users looking for legitimate software such as Notepad++ and VNote on search engines like Baidu are being targeted with malicious ads and bogus links to distribute trojanized versions of the software and ultimately deploy  Geacon , a Golang-based implementation of Cobalt Strike. "The malicious site found in the notepad++ search is distributed through an advertisement block," Kaspersky researcher Sergey Puzan  said . "Opening it, an attentive user will immediately notice an amusing inconsistency: the website address contains the line vnote, the title offers a download of Notepad‐‐ (an analog of Notepad++, also distributed as open-source software), while the image proudly shows Notepad++. In fact, the packages downloaded from here contain Notepad‐‐." The website, named vnote.fuwenkeji[.]cn, contains download links to Windows, Linux, and macOS versions of the software, with the link to the Windows variant pointing to the official  Gitee repository  containin...

The North Korea-linked nation-state actor known as Kimsuky is suspected of using a previously undocumented Golang-based information stealer called  Troll Stealer . The malware steals "SSH, FileZilla, C drive files/directories, browsers, system information, [and] screen captures" from infected systems, South Korean cybersecurity company S2W  said  in a new technical report. Troll Stealer's links to Kimsuky stem from its similarities to known malware families, such as AppleSeed and AlphaSeed malware that have been attributed to the group. Kimsuky, also tracked under the names APT43, ARCHIPELAGO, Black Banshee, Emerald Sleet (previously Thallium), Nickel Kimball, and Velvet Chollima, is well known for its propensity to steal sensitive, confidential information in offensive cyber operations. In late November 2023, the threat actors were  sanctioned  by the U.S. Treasury Department's Office of Foreign Assets Control (OFAC) for gathering intelligence to further ...

The threat actor behind a peer-to-peer (P2P) botnet known as  FritzFrog  has made a return with a new variant that leverages the  Log4Shell vulnerability  to propagate internally within an already compromised network. "The vulnerability is exploited in a brute-force manner that attempts to target as many vulnerable Java applications as possible," web infrastructure and security company Akamai said in a report shared with The Hacker News. FritzFrog,  first documented  by Guardicore (now part of Akamai) in August 2020, is a Golang-based malware that primarily targets internet-facing servers with weak SSH credentials. It's known to be active since January 2020. It has  since evolved  to strike healthcare, education, and government sectors as well as improved its capabilities to ultimately deploy cryptocurrency miners on infected hosts, claiming more than 1,500 victims over the years. What's novel about the latest version is the use of the Log4...

The Iranian nation-state actor known as  MuddyWater  has leveraged a newly discovered command-and-control (C2) framework called MuddyC2Go in its attacks on the telecommunications sector in Egypt, Sudan, and Tanzania. The Symantec Threat Hunter Team, part of Broadcom, is  tracking  the activity under the name Seedworm, which is also tracked under the monikers Boggy Serpens, Cobalt Ulster, Earth Vetala, ITG17, Mango Sandstorm (formerly Mercury), Static Kitten, TEMP.Zagros, and Yellow Nix. Active since at least 2017,  MuddyWater  is assessed to be affiliated with Iran's Ministry of Intelligence and Security (MOIS), primarily singling out entities in the Middle East. The cyber espionage group's use of  MuddyC2Go  was first highlighted by Deep Instinct last month, describing it as a Golang-based replacement for  PhonyC2 , itself a successor to MuddyC3. However, there is evidence to suggest that it may have been employed as early as 2020. Whi...

The Pakistan-linked threat actor known as  SideCopy  has been observed leveraging the recent WinRAR security vulnerability in its attacks targeting Indian government entities to deliver various remote access trojans such as AllaKore RAT, Ares RAT, and DRat. Enterprise security firm SEQRITE described the campaign as multi-platform, with the attacks also designed to infiltrate Linux systems with a compatible version of Ares RAT. SideCopy, active since at least 2019, is  known  for its  attacks  on Indian and Afghanistan entities. It's suspected to be a sub-group of the Transparent Tribe (aka APT36) actor. "Both SideCopy and APT36 share infrastructure and code to aggressively target India," SEQRITE researcher Sathwik Ram Prakki  said  in a Monday report. Earlier this May, the group was  linked  to a phishing campaign that took advantage of lures related to India's Defence Research and Development Organization (DRDO) to deliver inform...

The threat actors behind the  DDoSia  attack tool have come up with a new version that incorporates a new mechanism to retrieve the list of targets to be bombarded with junk HTTP requests in an attempt to bring them down. The updated variant, written in Golang, "implements an additional security mechanism to conceal the list of targets, which is transmitted from the [command-and-control] to the users," cybersecurity company Sekoia  said  in a technical write-up. DDoSia is attributed to a pro-Russian hacker group called  NoName(057)16 . Launched in 2022 and a successor of the  Bobik botnet , the attack tool is  designed  for staging distributed denial-of-service (DDoS) attacks against targets primarily located in Europe as well as Australia, Canada, and Japan. Lithuania, Ukraine, Poland, Italy, Czechia, Denmark, Latvia, France, the U.K., and Switzerland have emerged as the most targeted countries over a period ranging from May 8 to June 26, 202...

A highly targeted cyber attack against an East Asian IT company involved the deployment of a custom malware written in Golang called  RDStealer . "The operation was active for more than a year with the end goal of compromising credentials and data exfiltration," Bitdefender security researcher Victor Vrabie  said  in a technical report shared with The Hacker News. Evidence gathered by the Romanian cybersecurity firm shows that the campaign – dubbed RedClouds – started in early 2022. The targeting aligns with the interest of China-based threat actors. In the early phases, the operation relied on readily available remote access and post-exploitation tools like AsyncRAT and Cobalt Strike, before transitioning to bespoke malware in late 2021 or early 2022 in a bid to thwart detection. A primary evasion tactic concerns the use of Microsoft Windows folders that are likely to be excluded from scanning by security software (e.g., System32 and Program Files) to store the back...

A new Golang-based information stealer called  Skuld  has compromised Windows systems across Europe, Southeast Asia, and the U.S. "This new malware strain tries to steal sensitive information from its victims," Trellix researcher Ernesto Fernández Provecho  said  in a Tuesday analysis. "To accomplish this task, it searches for data stored in applications such as Discord and web browsers; information from the system and files stored in the victim's folders." Skuld, which shares overlaps with publicly available stealers like  Creal Stealer ,  Luna Grabber , and  BlackCap Grabber , is the handiwork of a developer who goes by the online alias Deathined on various social media platforms like GitHub, Twitter, Reddit, and Tumblr. Also spotted by Trellix is a Telegram group named deathinews, indicating that these online avenues could be used to promote the offering in the future as a service for other threat actors. The malware, upon execution, checks if...
