File transfer services such as FTP or HTTP has been the most common way of file transfer for business requirements. Typically what a file transfer means is that a file transfer protocol such as FTP or HTTP is used to send the stream of bits stored as a single unit in a file system including file name, file size, timestamp and other metadata from one host to another host over a TCP-based network such as the Internet. But this process is not foolproof. FTP, by itself, is not a secure file transfer protocol and it has a lot of security vulnerabilities. It’s a known fact that FTP doesn’t provide any encryption for data transfer. Most of the times, the requirement in any business is pretty simple: to transfer files between two endpoints in different locations, and the parties involved do not think much about how secure the file transfer process is going to be. Using FTP for official file transfer can leave your data transmission exposed to many security attacks: FTP Bounce Attack Gener...

VMware on Tuesday published a new bulletin warning of as many as 19 vulnerabilities in vCenter Server and Cloud Foundation appliances that a remote attacker could exploit to take control of an affected system. The most urgent among them is an arbitrary file upload vulnerability in the Analytics service (CVE-2021-22005) that impacts vCenter Server 6.7 and 7.0 deployments. "A malicious actor with network access to port 443 on vCenter Server may exploit this issue to execute code on vCenter Server by uploading a specially crafted file," the company  noted ,  adding  "this vulnerability can be used by anyone who can reach vCenter Server over the network to gain access, regardless of the configuration settings of vCenter Server." Although VMware has published  workarounds  for the flaw, the company cautioned that they are "meant to be a temporary solution until updates […] can be deployed." The complete list of flaws patched by the virtualization services ...

Cybersecurity researchers have discovered severe cryptographic issues in various end-to-end encrypted (E2EE) cloud storage platforms that could be exploited to leak sensitive data. "The vulnerabilities range in severity: in many cases a malicious server can inject files, tamper with file data, and even gain direct access to plaintext," ETH Zurich researchers Jonas Hofmann and Kien Tuong Truong said . "Remarkably, many of our attacks affect multiple providers in the same way, revealing common failure patterns in independent cryptographic designs." The identified weaknesses are the result of an analysis of five major providers such as Sync, pCloud, Icedrive, Seafile, and Tresorit. The devised attack techniques hinge on a malicious server that's under an adversary's control, which could then be used to target the service providers' users. A brief description of the flaws uncovered in the cloud storage systems is as follows - Sync, in which a maliciou...

A security researcher has discovered a serious vulnerability in the default configuration of the latest version of Google's Chrome running on any version of Microsoft's Windows operating system, including Windows 10, that could allow remote hackers to steal user's login credentials. Researcher Bosko Stankovic of DefenseCode has found that just by visiting a website containing a malicious SCF file could allow victims to unknowingly share their computer's login credentials with hackers via Chrome and the SMB protocol. This technique is not new and was exploited by the Stuxnet — a powerful malware that specially designed to destroy Iran's nuclear program — that used the Windows shortcut LNK files to compromise systems. What’s make this attack different from others is the fact that such SMB authentication related attacks have been first time demonstrated on Google Chrome publicly, after Internet Explorer (IE) and Edge. Chrome + SCF + SMB = Stealing Windows...

Researchers have unearthed a dangerous backdoor in Microsoft's Outlook Web Application (OWA) that has allowed hackers to steal e-mail authentication credentials from major organizations. The Microsoft Outlook Web Application or OWA is an Internet-facing webmail server that is being deployed in private companies and organisations to provide internal emailing capabilities. Researchers from security vendor Cybereason discovered a suspicious DLL file loaded into the company's OWA server that siphoned decrypted HTTPS server requests. Although the file had the same name as another benign DLL file, the suspicious DLL file was unsigned and loaded from another directory. Hackers Placed Malicious DLL on OWA Server According to the security firm, the attacker replaced the OWAAUTH.dll file ( used by OWA as part of the authentication mechanism ) with one that contained a dangerous backdoor. Since it ran on the OWA server, the backdoored DLL file allowed hacker...

The threat actor known as Transparent Tribe has been attributed to a fresh set of attacks targeting Indian governmental, academic, and strategic entities with a remote access trojan (RAT) that grants them persistent control over compromised hosts. "The campaign employs deceptive delivery techniques, including a weaponized Windows shortcut (LNK) file masquerading as a legitimate PDF document and embedded with full PDF content to evade user suspicion," CYFIRMA said in a technical report. Transparent Tribe, also called APT36, is a hacking group that's known for mounting cyber espionage campaigns against Indian organizations. Assessed to be of Pakistani origin, the state-sponsored adversary has been active since at least 2013. The threat actor boasts of an ever-evolving arsenal of RATs to realize its goals. Some of the trojans put to use by Transparent Tribe in recent years include CapraRAT , Crimson RAT , ElizaRAT , and DeskRAT . The latest set of attacks began with ...

The popular SSH client program PuTTY has released the latest version of its software that includes security patches for 8 high-severity security vulnerabilities. PuTTY is one of the most popular and widely used open-source client-side programs that allows users to remotely access computers over SSH, Telnet, and Rlogin network protocols. Almost 20 months after releasing the last version of its software, the developers of PuTTY earlier this week released the latest version 0.71 for Windows and Unix operating systems. According to an advisory available on its website, all previous versions of the PuTTY software have been found vulnerable to multiple security vulnerabilities that could allow a malicious server or a compromised server to hijack client's system in different ways. Here below I have listed all 8 vulnerabilities with brief information that PuTTY 0.71 has patched: 1) Authentication Prompt Spoofing — Since PuTTY doesn't have a way to indicate whether a piec...

WikiLeaks has published a new batch of the ongoing Vault 7 leak , this time detailing an alleged CIA project that allowed the agency to turn Windows file servers into covert attack machines that can silently infect other computers of interest inside a targeted network. Codenamed Pandemic , the tool is a persistent implant for Microsoft Windows machines that share files with remote users on a local network. The documents leaked by the whistleblower organisation date from April 2014 to January 2015. According to WikiLeaks, Pandemic infect networks of Windows computers through the Server Message Block (SMB) file sharing protocol by replacing application code on-the-fly with a trojanized version of the software. "Pandemic is a tool which is run as kernel shellcode to install a file system filter driver," a leaked CIA manual reads. "The filter will 'replace' a target file with the given payload file when a remote user accesses the file via SMB (read-only, not w...

We don't really know the pain and cost of a downtime event unless we are directly touched. Be it a flood, electrical failure, ransomware attack or other broad geographic events; we don't know what it is really like to have to restore IT infrastructure unless we have had to do it ourselves. We look at other people's backup and recovery issues and hope we are smarter or clever enough to keep it from happening to us. Recovery from a downtime event includes inconvenience, extra work, embarrassment and yes, real pain. A ransomware attack is a good example. Unitrends—an American company specialised in backup and business continuity solutions—recently shared with us a real cyber-attack incident happened with one of their customers to describe the required steps they took to recover functionality following a CryptoLocker attack against a US city. Also, how it cost city's Governance team days of production and hundreds of man-hours to recover. The Challenge ...

Cybersecurity researchers have discovered a case of "forced authentication" that could be exploited to leak a Windows user's NT LAN Manager (NTLM) tokens by tricking a victim into opening a specially crafted Microsoft Access file. The attack takes advantage of a legitimate feature in the database management system solution that allows users to  link to external data sources , such as a remote SQL Server table. "This feature can be abused by attackers to automatically leak the Windows user's NTLM tokens to any attacker-controlled server, via any TCP port, such as port 80," Check Point security researcher Haifei Li  said . "The attack can be launched as long as the victim opens an .accdb or .mdb file. In fact, any more-common Office file type (such as a .rtf ) can work as well." NTLM, an authentication protocol introduced by Microsoft in 1993, is a challenge-response protocol that's used to authenticate users during sign-in. Over the years, ...

A German security researcher has publicly disclosed details of a serious vulnerability in one of the most popular FTP server applications, which is currently being used by more than one million servers worldwide. The vulnerable software in question is ProFTPD , an open source FTP server used by a large number of popular businesses and websites including SourceForge, Samba and Slackware, and comes pre-installed with many Linux and Unix distributions, like Debian. Discovered by Tobias Mädel , the vulnerability resides in the mod_copy module of the ProFTPD application, a component that allows users to copy files/directories from one place to another on a server without having to transfer the data to the client and back. According to Mädel, an incorrect access control issue in the mod_copy module could be exploited by an authenticated user to unauthorizedly copy any file on a specific location of the vulnerable FTP server where the user is otherwise not allowed to write a file. ...

A set of three security vulnerabilities has been disclosed in mcp-server-git , the official Git Model Context Protocol ( MCP ) server maintained by Anthropic, that could be exploited to read or delete arbitrary files and execute code under certain conditions. "These flaws can be exploited through prompt injection, meaning an attacker who can influence what an AI assistant reads (a malicious README, a poisoned issue description, a compromised webpage) can weaponize these vulnerabilities without any direct access to the victim's system," Cyata researcher Yarden Porat said in a report shared with The Hacker News. Mcp-server-git is a Python package and an MCP server that provides a set of built-in tools to read, search, and manipulate Git repositories programmatically via large language models (LLMs). The security issues, which have been addressed in versions 2025.9.25 and 2025.12.18 following responsible disclosure in June 2025, are listed below - CVE-2025-68143 (CV...

The advanced persistent threat (APT) actor known as SideWinder has been accused of deploying a backdoor in attacks directed against Pakistan government organizations as part of a campaign that commenced in late November 2022. "In this campaign, the SideWinder advanced persistent threat (APT) group used a server-based polymorphism technique to deliver the next stage payload," the BlackBerry Research and Intelligence Team  said  in a technical report published Monday. Another campaign discovered by the Canadian cybersecurity company in early March 2023 shows that Turkey has also landed in the crosshairs of the threat actor's collection priorities. SideWinder  has been on the radar since at least 2012 and it's primarily known to target various Southeast Asian entities located across Pakistan, Afghanistan, Bhutan, China, Myanmar, Nepal, and Sri Lanka. Suspected to be an Indian state-sponsored group, SideWinder is also tracked under the monikers APT-C-17, APT-Q-39, Ha...

Beware! If you have downloaded PHP PEAR package manager from its official website in past 6 months, we are sorry to say that your server might have been compromised. Last week, the maintainers at PEAR took down the official website of the PEAR ( pear-php.net ) after they found that someone has replaced original PHP PEAR package manager (go-pear.phar) with a modified version in the core PEAR file system. Though the PEAR developers are still in the process of analyzing the malicious package, a security announcement published on January 19, 2019, confirmed that the allegedly hacked website had been serving the installation file contaminated with the malicious code to download for at least half a year. The PHP Extension and Application Repository (PEAR) is a community-driven framework and distribution system that offers anyone to search and download free libraries written in PHP programming language. These open-source libraries (better known as packages) allows developers to ea...
