2. Hackers Are Using This Phishing Technique to Trick Unsuspecting Victims

Phishing just got more sophisticated. According to researchers at Barracuda Networks, hackers are using a technique known as conversation-hijacking to infiltrate real-business email threads.

3. Dangerous Vulnerability Affecting Windows 10 Computers

The National Security Agency (NSA) has uncovered a critical vulnerability in the Windows cryptographic functionality that could enable an attacker to carry out a remote code execution attack. The vulnerability affects Windows 10, as well as, Windows Server 2016 and 2019. The vulnerability is located in a core Windows component known as crypt32.dll, which enables software developers to access digital certificates and other cryptographic functions. The NSA recommended that everyone install Microsoft’s Patch Tuesday patches as soon as possible


4. Firefox Vulnerability Being Exploited in the Wild

Anybody can log into WordPress as an administrator if the site is using vulnerable InfiniteWP Client and WP Time Capsule plugins, warned researchers from WebARX. The developer of the plugins released patches for logical issues in the code that caused the vulnerability after being informed of the problem by WebARX. The researchers said that it is hard to block the vulnerabilities with general firewall rules because malware would appear to be the same as a legitimate-looking payload. Based on the WordPress plugins library, the InfiniteWP plugin is installed in more than 300,000 websites and the WP Time Capsule plugin is active on more than 20,000 websites.
