Security researchers have raised an alarm about a new DDoS attack. They have warned that the WS-Discovery (WSD) protocol is currently being abused for massive DDoS attacks. The protocol is used by about 630,000 devices worldwide, which makes them quite vulnerable to attacks.

Several instances of phishing email attacks have been noticed in the past 24 hours. In one instance, the technique is being used to deliver Amadey botnet to taxpayers in the U.S, while in another incident, the attackers are stealing Microsoft login credentials from users by utilizing SmtpJS service.

The past 24 hours also saw a major evolution in Magecart card-skimming attack. The attackers behind the recent attacks have injected the card-skimming script on the websites of two hotel chains which are spread across 14 countries. The purpose of this malicious script is to steal data from payment forms including credit card details, names, email addresses, telephone numbers, and hotel room preferences.

Researchers note that there are more than 630,000 devices that are vulnerable to WSD attacks.

WannaCry terror continues
Researchers have concluded that there are more than 12,000 variants of WannaCry ransomware since it was first discovered in 2017. These variants are still active and quite capable of spreading broken copies of themselves to Windows computers that have not been patched.

Amadey botnet
A new phishing campaign has been spotted delivering Amadey botnet to taxpayers in the U.S. The malware is distributed via fake income tax refund emails that pretend to be from the Internal Revenue Service (IRS). Instead of asking the victims to provide their login credentials, the email includes a temporary username and password to log into the fake IRS portal.

Microsoft account phishing scam
A new Microsoft account phishing scam has been discovered that utilizes the SmtpJS service to steal credentials from users. The scam is initiated through a phishing email that comes embedded with a fake Microsoft login page. When users submit their credentials, the page typically saves them to a database controlled by the attackers and tells that submitted credentials are incorrect.

Restaurant Depot phishing campaign
Customers of commercial foodservice wholesaler Restaurant Depot were targeted in phishing emails that asked them for payment of an outstanding invoice. The email further warned that failing to pay the amount would result in a deduction of balance from their accounts.

IT support scam
Federal authorities are investigating a massive IT support scam that affected more than 7,500 victims. These victims were convinced their computers needed fixing after being displayed a fake warning. The warning which appears as a pop-up, asks the victim to call on a number provided in order to get rid of their system infection.

The scam has resulted in a loss of around $10 million for the victims.
