Drive-by Downloads

This post is part of our Cyber Threat Series.

The Challenge:

Drive-by downloads are exploit kits that download invisibly from infected websites. These websites may be malicious sites built for malware distribution or trusted sites infected by hackers. Many of these attacks take advantage of weaknesses in popular software and tools, including video players, Java, and Adobe Reader.

Downloads may install and run other malware or may themselves be malicious. Many drive-by downloads install cryptoware, or ransomware, that encrypts files and holds them for ransom.

What to Do:

User education and web protection are the best protection from drive-by downloads. Cyber-aware users understand the risks and can avoid malicious links and sites. Web protection can prevent unexpected downloads and malicious behavior from reaching your systems and users.

DNS protection and secure DNS services provide additional protection by preventing impersonation, hijacking, and domain level attacks.

Brute Force Attack

This post is part of our Cyber Threat Series.

The Challenge:

Hackers use Brute Force Attacks to target a single service exposed to the Internet, including Remote Desktop, Outlook Web Access, and email services. Brute Force Attacks gain access by trying every viable access method or password.

Hackers use these attacks to access your data or to install other malware within your systems. Patient hackers space out attempts; they are difficult to notice or detect. When hackers rush, the impact can be similar to a DDOS attack.

Hackers can launch Brute Force Attacks externally or from malware-infected systems on your network. Internal attacks often target specific systems and vulnerabilities, such as SQL Server and SQL Injection vulnerabilities.

What to Do:

Require robust passwords; they are your first protection from Brute Force Attacks. Put controls in place to enforce best-practice password structure and expiring passwords can thwart an attack.

Deploy Multi-Factor Authentication. MFA creates and additional level of protection since a compromised password is not sufficient for access.

To protect against internal attacks, ensure systems run current operating system versions. Keep all systems current with patches and updates.

Deploy “Next Gen” protections to keep Brute Force Attack malware from making it onto your servers and clients:

  • Advanced threat protection (ATP) for email
  • Endpoint and mobile device protection
  • DNS security and protection
  • Web protection and filtering
