Except for phishing and scams, downloading an HTML attachment and opening it locally on your browser was never considered as a severe threat until a security researcher today demonstrated a technique that could allow attackers to steal files stored on a victim's computer. Barak Tawily, an application security researcher, shared his findings with The Hacker News, wherein he successfully developed a new proof-of-concept attack against the latest version of Firefox by leveraging a 17-year-old known issue in the browser. The attack takes advantage of the way Firefox implements Same Origin Policy (SOP) for the "file://" scheme URI (Uniform Resource Identifiers), which allows any file in a folder on a system to get access to files in the same folder and subfolders. Since the Same Origin Policy for the file scheme has not been defined clearly in the RFC by IETF, every browser and software have implemented it differently—some treating all files in a folder as the same

A security researcher has discovered a critical vulnerability in Facebook Messenger that could allow an attacker to read all your private conversation, affecting the privacy of around 1 Billion Messenger users. Ysrael Gurt, the security researcher at BugSec and Cynet, reported a cross-origin bypass-attack against Facebook Messenger which allows an attacker to access your private messages, photos as well as attachments sent on the Facebook chat. To exploit this vulnerability, all an attacker need is to trick a victim into visiting a malicious website; that's all. Once clicked, all private conversations by the victim, whether from a Facebook's mobile app or a web browser, would be accessible to the attacker, because the flaw affected both the web chat as well as the mobile application. Dubbed " Originull ," the vulnerability actually lies in the fact that Facebook chats are managed from a server located at {number}-edge-chat.facebook.com, which is separate from

Account takeover attacks have emerged as one of the most persistent and damaging threats to cloud-based SaaS environments. Yet despite significant investments in traditional security measures, many organizations continue to struggle with preventing these attacks. A new report, " Why Account Takeover Attacks Still Succeed, and Why the Browser is Your Secret Weapon in Stopping Them " argues that the browser is the primary battleground where account takeover attacks unfold and, thus, where they should be neutralized. The report also provides effective guidance for mitigating the account takeover risk.  Below are some of the key points raised in the report: The Role of the Browser in Account Takeovers According to the report, the SaaS kill chain takes advantage of the fundamental components that are contained within the browser. For account takeover, these include: Executed Web Pages - Attackers can create phishing login pages or use MiTM over legitimate web pages to harve
