Has Yahoo rebuilt your trust again? If yes, then you need to think once again, as the company is warning its users of another hack. Last year, Yahoo admitted two of the largest data breaches on record. One of which that took place in 2013 disclosed personal details associated with more than 1 Billion Yahoo user accounts . Well, it's happened yet again. Yahoo sent out another round of notifications to its users on Wednesday, warning that their accounts may have been compromised as recently as last year after an ongoing investigation turned up evidence that hackers used forged cookies to log accounts without passwords. The company quietly revealed the data breach in security update in December 2016, but the news was largely overlooked, as the statement from Yahoo provided information on a separate data breach that occurred in August 2013 involving more than 1 billion accounts. The warning message sent Wednesday to some Yahoo users read: "Based on the ongoing i...

Update: A hacker yesterday claimed to have hacked the FBI's website running on Plone CMS, but it seems it wasn't hacked using any zero-day vulnerability in Plone. We contacted Plone security team and updated this story (see below) with official statements. A hacker, using Twitter handle CyberZeist , has claimed to have hacked the FBI's website (fbi.gov) and leaked personal account information of several FBI agents publically. CyberZeist had initially exposed the flaw on 22 December, giving the FBI time to patch the vulnerability in its website's code before making the data public. The hacker exploited a zero-day vulnerability in the Plone CMS , an Open Source Content Management software used by FBI to host its website, and leaked personal data of 155 FBI officials to Pastebin , including their names, passwords, and email accounts. CyberZeist tweeted multiple screenshots as proof of his claims, showing his unauthorized access to server and database files usi...

Serverless environments, leveraging services such as AWS Lambda, offer incredible benefits in terms of scalability, efficiency, and reduced operational overhead. However, securing these environments is extremely challenging. The core of current serverless security practices often revolves around two key components: log monitoring and static analysis of code or system configuration. But here is the issue with that: 1. Logs Only Tell Part of the Story Logs can track external-facing activities, but they don't provide visibility into the internal execution of functions. For example, if an attacker injects malicious code into a serverless function that doesn't interact with external resources (e.g., external APIs or databases), traditional log-based tools will not detect this intrusion. The attacker may execute unauthorized processes, manipulate files, or escalate privileges—all without triggering log events. 2. Static Misconfiguration Detection is Incomplete Static tools that check ...

Nearly two years back, we warned users about publicly accessible MongoDB instances – almost 600 Terabytes (TB) – over the Internet which require no authentication, potentially leaving websites and servers at risk of hacking. These MongoDB instances weren't exposed due to any flaw in its software, but due to a misconfiguration (bad security practice) that let any remote attacker access MongoDB databases without using any special hacking tool. MongoDB later resolved the issue in the next version of its software by setting unrestricted remote access by default in the configuration, thousands of site administrators have not updated their servers yet. But trust me, they'll now regret this! A Hacker is now hijacking and wiping out unsecured MongoDB databases , but keeping a copy of those databases for asking administrators a ransom of 0.2 Bitcoins (nearly US$211) to return the lost data. So, admins without backups are left in a bind. In fact, the rising price of Bitcoin...

Three critical zero-day vulnerabilities have been discovered in PHP 7 that could allow an attacker to take complete control over 80 percent of websites which run on the latest version of the popular web programming language. The critical vulnerabilities reside in the unserialized mechanism in PHP 7 – the same mechanism that was found to be vulnerable in PHP 5 as well, allowing hackers to compromise Drupal, Joomla, Magento, vBulletin and PornHub websites and other web servers in the past years by sending maliciously crafted data in client cookies. Security researchers at Check Point's exploit research team spent several months examining the unserialized mechanism in PHP 7 and discovered "three fresh and previously unknown vulnerabilities" in the mechanism. While researchers discovered flaws in the same mechanism, the vulnerabilities in PHP 7 are different from what was found in PHP 5. Tracked as CVE-2016-7479, CVE-2016-7480, and CVE-2016-7478, the zero-day flaw...

Sometimes I receive emails from our readers who wanted to know how to hack Facebook account , but just to delete some of their messages they have sent to their friends or colleagues mistakenly or under wrong circumstances like aggression. How to hack a Facebook account? It is probably the biggest "n00b" question you will see on the Internet. The solution for this query is hard to find — but recently researchers have shown that how you can modify or alter your messages once you have pressed the SEND button in Facebook Messenger. According to the researcher  Roman Zaikin  from cyber security firm Check Point , a simple HTML tweak can be used to exploit Facebook online chat as well as its Messenger app, potentially allowing anyone to modify or delete any of his/her sent message, photo, file, and link. Though the bug is simple, it could be exploited by malicious users to send a legitimate link in a Facebook chat or group chat, and later change it to a malicious link t...

Joomla – one of the most popular open source Content Management System (CMS) software packages, has reportedly patched three critical vulnerabilities in its software.

While Google Cloud Security Scanner will be ea...

The popular copy and paste website ' Pastebin ' created a decade ago for software developers and even by hackers groups to share source code, dumps and stolen data, has more recently been leveraged by cyber criminals to target millions of users. Compromising a website and then hosting malware on it has become an old tactic for hackers, and now they are trying their hands in compromising vast majority of users in a single stroke. Researchers have discovered that hackers are now using Pastebin to spread malicious backdoor code. According to a blog post published yesterday by a senior malware researcher at Sucuri , Denis Sinegubko, the hackers are leveraging the weakness in older versions of the RevSlider , a popular and a premium WordPress plugin. The plugin comes packaged and bundled into the websites' themes in such a way that many website owners don't even know they have it. In order to exploit the vulnerability, first hackers look for a RevSlider plugin i...

SQL Injection (SQLi) attacks have been around for over a decade. You might wonder why they are still so prevalent. The main reason is that they still work on quite a few web application targets. In fact, according to Veracode's 2014 State of Security Software Report , SQL injection vulnerabilities still plague 32% of all web applications. One of the big reasons is the attractiveness of the target – the database typically contains the interesting and valuable data for the web application. A SQLi attack involves inserting a malformed SQL query into an application via client-side input. The attack perverts the intentions of web programmers who write queries and provide input methods that can be exploited. There is a reason they're on the OWASP Top 10 . Termed " injection flaws ", they can strike not only SQL, but operating systems and LDAP can fall prey to SQLi. They involve sending untrusted data to the interpreter as a part of the query. The attack tricks the interpreter into ...
