" If you want to keep living, Pay a ransom, or die ." This could happen, as researchers have found thousands of vulnerabilities in Pacemakers that hackers could exploit. Millions of people that rely on pacemakers to keep their hearts beating are at risk of software glitches and hackers, which could eventually take their lives. A pacemaker is a small electrical battery-operated device that's surgically implanted in the chest to help control the heartbeats. This device uses low-energy electrical pulses to stimulate the heart to beat at a normal rate. While cyber security firms are continually improving software and security systems to protect systems from hackers, medical devices such as insulin pumps or pacemakers are also vulnerable to life-threatening hacks. In a recent study, researchers from security firm White Scope analysed seven pacemaker products from four different vendors and discovered that they use more than 300 third-party libraries, 174 of which are...

Cybersecurity researchers have found that it's possible for attackers to weaponize improperly configured Jenkins Script Console instances to further criminal activities such as cryptocurrency mining. "Misconfigurations such as improperly set up authentication mechanisms expose the '/script' endpoint to attackers," Trend Micro's Shubham Singh and Sunil Bharti said in a technical write-up published last week. "This can lead to remote code execution (RCE) and misuse by malicious actors." Jenkins, a popular continuous integration and continuous delivery ( CI/CD ) platform, features a Groovy script console that allows users to run arbitrary Groovy scripts within the Jenkins controller runtime. The project maintainers, in the official documentation, explicitly note that the web-based Groovy shell can be used to read files containing sensitive data (e.g., "/etc/passwd"), decrypt credentials configured within Jenkins, and even reconfigure sec...

Thanks to recent events involving certain celebrities' stolen pictures, "brute-force attack" is now one of the hot buzz words making its rounds. As an IT professional - do you know what a brute force attack is, how to spot one when it happens, and how to prevent it? A brute-force attack is, simply, an attack on a username, password, etc. that systematically checks all possible combinations until the correct one is found. Scripts are usually used in these attacks to automate the process of arriving at the correct username/password combination. This is why time is of the essence when it comes to detecting and stopping a brute force attack – the more time the attacker has, the more passwords can be tried. Brute force attacks are one of the few hacks detectable by their volume, rather than their type. In your web (or proprietary app) logs, you'll usually see a crazy amount of failed login attempts, usually originating from the same IP address. You might even see the same accoun...

Critical security flaws in Cacti, Realtek, and IBM Aspera Faspex are being exploited by various threat actors in hacks targeting unpatched systems. This entails the abuse of  CVE-2022-46169  (CVSS score: 9.8) and  CVE-2021-35394  (CVSS score: 9.8) to deliver  MooBot  and  ShellBot  (aka PerlBot), Fortinet FortiGuard Labs  said  in a report published this week. CVE-2022-46169  relates to a critical authentication bypass and command injection flaw in Cacti servers that allows an unauthenticated user to execute arbitrary code.  CVE-2021-35394  also concerns an arbitrary command injection vulnerability impacting the Realtek Jungle SDK that was patched in 2021. While the latter has been previously exploited to distribute botnets like Mirai, Gafgyt, Mozi, and RedGoBot, the development marks the first time it has been utilized to deploy MooBot, a Mirai variant known to be active since 2019. The Cacti flaw, besides being lev...
