The latest versions of UC Browser and UC Browser Mini Android apps have been found to be vulnerable to URL spoofing attacks. These browsers have over 600 million installs across the world.

  • It is masquerading as an ESET AV Remover Installer to trick users into downloading it.
  • The new variant is distributed via spam emails.

A new variant of Dharma ransomware has been found that uses a new technique to hide its malicious activities. It is masquerading as an ESET AV Remover Installer to trick users into downloading it.

How does it propagate?

The new variant is distributed via the old-school spam email technique. The email comes attached with a password-protected self-extracting archive named ‘Defender.exe’. If the users click on the download link, they are prompted for a password that is provided in the message.

Once the file is unlocked, the archive drops the malicious file ‘taskhost.exe’ as well as the installer of an old version of ESET AV remover renamed as ‘Defender_nt32_enu.exe. Trend Micro researchers have identified the new version of Dharma ransomware as RANSOM.WIN32.DHARMA.THDAAAI.

What happens after the installation?

Once the Dharma ransomware variant is installed, it starts encrypting files in the background and the ESET AV Remover Installation begins. The victim will see the ESET GUI screen, a distraction from Dharma’s malicious activities.

Bottom line

ESET has been informed about the issue. In return, the firm has explained that the AV Remover Installer is executed only after a user’s interaction. Hence, users should be cautious while downloading such AV software.

What is Firewall? A Firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies. At its most basic, a firewall is essentially the barrier that sits between a private internal network and the public Internet.

 

Secure your network at the gateway against threats such as intrusions, Viruses, Spyware, Worms, Trojans, Adware, Keyloggers, Malicious Mobile Code (MMC), and other dangerous applications for total protection in a convenient, affordable subscription-based service. Modern threats like web-based malware attacks, targeted attacks, application-layer attacks, and more have had a significantly negative effect on the threat landscape. In fact, more than 80% of all new malware and intrusion attempts are exploiting weaknesses in applications, as opposed to weaknesses in networking components and services. Stateful firewalls with simple packet filtering capabilities were efficient blocking unwanted applications as most applications met the port-protocol expectations. Administrators could promptly prevent an unsafe application from being accessed by users by blocking the associated ports and protocols.
