New shc-based Linux Malware Targeting Systems with Cryptocurrency Miner

New shc-based Linux Malware Targeting Systems with Cryptocurrency Miner

Jan 04, 2023 Linux / Cryptocurrency
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 serv

Flickr vulnerable to SQL Injection and Remote Code Execution Flaws

Apr 14, 2014
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 was successfu

Make a Fresh Start for 2024: Clean Out Your User Inventory to Reduce SaaS Risk

Make a Fresh Start for 2024: Clean Out Your User Inventory to Reduce SaaS Risk

Dec 04, 2023SaaS Security / Data Security
As work ebbs with the typical end-of-year slowdown, now is a good time to review user roles and privileges and remove anyone who shouldn't have access as well as trim unnecessary permissions. In addition to saving some unnecessary license fees, a clean user inventory significantly enhances the security of your SaaS applications. From reducing risk to protecting against data leakage, here is how you can start the new year with a clean user list.  How Offboarded Users  Still  Have Access to Your Apps When employees leave a company, they trigger a series of changes to backend systems in their wake. First, they are removed from the company's identity provider (IdP), which kicks off an automated workflow that deactivates their email and removes access to all internal systems. When enterprises use an SSO (single sign-on), these former employees lose access to any online properties – including SaaS applications – that require SSO for login.  However, that doesn't mean that former employee

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 this makes quite
