Launching a cyber attack by exploiting known vulnerabilities has always been a go-to approach for malicious actors. Hence, it is very necessary for organizations to immediately patch the vulnerabilities or look out for mitigation measures to stay safe from attacks. Lately, Microsoft and Citrix have released fixes for a zero-day vulnerability and a NetScaler vulnerability respectively affecting their products. While Microsoft’s zero-day vulnerability that impacts the Internet Explorer comes with only workarounds and mitigations until a patch is released, Citrix has issued permanent security patches for the flaw affecting Citrix Application Delivery Controller (ADC) versions 11.1 and 12.0. 

Talking about data breaches, an operator of a DDoS booter service has shared a massive list of Telnet credentials on a popular hacking forum. The stolen credentials belong to more than 515,000 servers, home routers, and IoT devices. Cybercriminals can purchase these credentials to hijack more smart devices and launch DDoS attacks or perform other malicious activities.

The ransomware does not affect the computers that have keyboard language set to Russian, Kazakh, Belarus, or Ukrainian.  

Top Vulnerabilities Reported in the Last 24 Hours

Microsoft discloses a zero-day flaw
Microsoft has published a security advisory for a zero-day vulnerability discovered in Internet Explorer. The vulnerability is currently being exploited in one of the targeted attacks conducted by the DarkHotel threat actor group.

Top Scams Reported in the Last 24 Hours

Tax scam
As the 2019-tax return file nears, recipients have started receiving phishing emails that alert them about fake W-2 forms. The phishing campaign is targeting some ADP users who are asked to click on a malicious link to view their W-2 forms. The malicious link is designed to look like an ADP login page. These domains are registered on the same day as the attack. From these malicious websites, attackers can steal the ADP usernames and passwords of unsuspecting victims who fall into the trap. With an employee’s credentials in hand, an attacker can expose bank account numbers or change their direct deposit information and redirect payments to attacker-controlled accounts.
