Cybersecurity researchers have discovered a new cryptojacking campaign that employs vulnerable drivers to disable known security solutions (EDRs) and thwart detection in what's called a Bring Your Own Vulnerable Driver ( BYOVD ) attack. Elastic Security Labs is tracking the campaign under the name REF4578 and the primary payload as GHOSTENGINE. Previous research from Chinese cybersecurity firm Antiy Labs has codenamed the activity as HIDDEN SHOVEL. "GHOSTENGINE leverages vulnerable drivers to terminate and delete known EDR agents that would likely interfere with the deployed and well-known coin miner," Elastic researchers Salim Bitam, Samir Bousseaden, Terrance DeJesus, and Andrew Pease said . "This campaign involved an uncommon amount of complexity to ensure both the installation and persistence of the XMRig miner." It all starts with an executable file ("Tiworker.exe"), which is used to run a PowerShell script that retrieves an obfuscated Power...

Three new malicious packages have been discovered in the Python Package Index (PyPI) open-source repository with capabilities to deploy a cryptocurrency miner on affected Linux devices. The three harmful packages, named modularseven, driftme, and catme, attracted a total of 431 downloads over the past month before they were taken down. "These packages, upon initial use, deploy a CoinMiner executable on Linux devices," Fortinet FortiGuard Labs researcher Gabby Xiong  said , adding the activity shares overlaps with a  prior campaign  that involved the use of a package called culturestreak to deploy a crypto miner. The malicious code resides in the __init__.py file, which decodes and retrieves the first stage from a remote server, a shell script ("unmi.sh") that fetches a configuration file for the mining activity as well as the CoinMiner file  hosted on GitLab . The  ELF binary  file is then executed in the background using the  nohup command , thu...

A new Linux malware developed using the shell script compiler ( shc ) has been observed deploying a cryptocurrency miner on compromised systems. "It is presumed that after successful authentication through a dictionary attack on inadequately managed Linux SSH servers, various malware were installed on the target system," AhnLab Security Emergency Response Center (ASEC)  said  in a report published today. shc allows shell scripts to be converted directly into binaries, offering protections against unauthorized source code modifications. It's analogous to the  BAT2EXE utility  in Windows that's used to convert any batch file to an executable. By using shc to generate ELF files, the idea is to protect the malicious shell commands from being inspected and potentially bypass detection by security software as the executables are encoded using the RC4 algorithm . In an attack chain detailed by the South Korean cybersecurity firm, a successful compromise of the SSH ser...

Is Managing Customer Logins and Data Giving You Headaches? You're Not Alone! Today, we all expect super-fast, secure, and personalized online experiences.

Yahoo-owned Flickr , one of the biggest online photo management and sharing website in the world was recently impacted by critical web application vulnerabilities, which left website's database and server vulnerable hackers. Ibrahim Raafat , a security researcher from Egypt has found SQL injection vulnerabilities on  Flickr Photo Books , new feature for printing custom photo books through Flickr that was launched 5 months ago. He claimed to have found two parameters ( page_id , items ) vulnerable to Blind SQL injection and one  (i.e. order_id ) Direct SQL Injection that allowed him to query the Flickr database for its content by the injection of a SQL SELECT statements. A Successful SQL exploitation could allow an attacker to steal the Database and MYSQL administrator password. Furthermore, Flickr's SQL injection flaws also facilitate the attacker to exploit remote code execution on the server and using  load_file("/etc/passwd")   function he wa...

One of the most popular Wordpress Plugin called " W3 Total Cache " which is used to Improve site performance and user experience via caching, having potential vulnerability. On Christmas day, someone disclose it on full-disclosure site that how a plugin misconfiguration leads to possible Wordpress cms hack. The loophole is actually activated on the fact that how W3TC stores the database cache. Jason disclosed that cache data is stored in public accessible directory, from where a malicious attack can can retrieve password hashes and other database information. Default location where this plugin stores data is " /wp-content/w3tc/dbcache/ " and if directory listing is enabled, attacker can browse and download it. He said," Even with directory listings off, cache files are by default publicly downloadable, and the key values / file names of the database cache items are easily predictable. " Because the plugin is very famous ,so thi...
