While phishing and ransomware dominate headlines, another critical risk quietly persists across most enterprises: exposed Git repositories leaking sensitive data. A risk that silently creates shadow access into core systems Git is the backbone of modern software development, hosting millions of repositories and serving thousands of organizations worldwide. Yet, amid the daily hustle of shipping code, developers may inadvertently leave behind API keys, tokens, or passwords in configuration files and code files, effectively handing attackers the keys to the kingdom. This isn't just about poor hygiene; it's a systemic and growing supply chain risk. As cyber threats become more sophisticated, so do compliance requirements. Security frameworks like NIS2, SOC2, and ISO 27001 now demand proof that software delivery pipelines are hardened and third-party risk is controlled. The message is clear: securing your Git repositories is no longer optional, it's essential. Below, we look at the ris...

With Web applications remaining a popular target for attackers, Web app security sometimes seems like a digital version of the " Good, the Bad and the Ugly ." Vulnerabilities in web applications are now the largest vector of enterprise security attacks. Web application security is much more challenging than infrastructure. The top Web application vulnerabilities occur and re-occur time and again. Items such as Cross Site Scripting (XSS), SQL Injection (SQLi) and file inclusion are common vulnerabilities and show up frequently. In his view, the majority of Web application security problems can be solved by applying well known security technology approaches. According to survey results, only 51 percent of organizations currently have coders conduct security testing, and only 40 percent of organizations report they test during development. Vulnerabilities like these fall often outside the traditional expertise of network security managers. To help you understa...

Businesses can leave themselves vulnerable to data theft and other online threats, particularly as security and IT budgets are under pressure while companies try to save money. Although budgets are tight, it is crucial for companies to stay protected online. On average, the total cost of security breaches, including lost business, in the UK last year was $2,565,702. Data theft and other online threats represent significant dangers for businesses in the UK. The economic downturn exacerbates this problem, leading many executives to cancel, defer, or downsize security budgets. To highlight the risks facing companies today, Astaro has compiled the following list of the five most serious internet security threats. 1. Browser Vulnerabilities No browser provider is immune to security holes. A recent example is the CSS bug that affected Internet Explorer versions 6, 7, and 8 (CVE-2010-3962). This bug targets computers in a two-stage attack: first, the user follows an email link to a webpag...

A vulnerability has been identified in Microsoft Internet Information Services (IIS) that causes the server to incorrectly handle files with multiple extensions separated by the ";" character. For instance, a file named "malicious.asp;.jpg" is treated as an ASP file. This flaw allows attackers to upload malicious executables to a vulnerable web server, bypassing file extension protections and restrictions. Notably, ASP.Net is NOT affected by this vulnerability. Impact and Versions Affected This vulnerability affects all versions of Microsoft IIS. It works successfully on IIS 6 and earlier versions. IIS 7 has not been tested, but it does not work on IIS 7.5. The vulnerability was discovered in April 2008 but reported in December 2009. Severity and Exploitation The impact on IIS is significant, as attackers can bypass file extension protections using a semi-colon after an executable extension, such as ".asp", ".cer", ".asa",...

A recent report suggests that focusing too much on new security threats might make companies overlook older, more commonly exploited vulnerabilities. The report by TrustWave is based on data from over 1,900 penetration tests and more than 200 data breach investigations for clients like American Express, MasterCard, Discover, Visa, and several large retailers. The analysis shows that major global companies are hiring "vulnerability chasers" who look for the latest vulnerabilities and zero-day threats while ignoring the most common ones. As a result, companies are being compromised by old, well-known vulnerabilities rather than new attack methods. For example, the top three ways hackers accessed corporate networks in 2009 were through remote access applications, trusted internal network connections, and SQL injection attacks. These attack methods have been well-known for years. SQL injection vulnerabilities, for instance, have been known for at least 10 years but are still c...
