Phishing and Spear Phishing

This post is part of our Cyber Threat Series.

The Challenge:

Cyber criminals prefer Phishing attacks. Phishing and Spear Phishing remain the primary vector for Malware attacks. Hackers evenly distribute attacks between two variants: Malicious Email Attachment (39.9%)  and Malicious Link (37.4%).

Leveraging human nature, phishing attacks look and feel like legitimate emails. Recipient often miss the cues that the email is fraudulent. We respond by clicking links to malicious websites, opening pictures or videos with hidden downloads, or opening infected attachments.

Advanced phishing attacks correlate public information from social media and pirated information from compromised systems to further personalize the attacks. These advanced attacks do a better job of hiding the malicious intent. As such, even savvy users fall prey.

What to Do:

The best protection is multi-level and multi-vector:

  • Teach your users about the risks and how they can help prevent attacks. User awareness leads to smart decisions on when to trust and when it’s safe to click.
  • Protect your devices with “Next Gen” endpoint protection. This includes your desktops, laptops, and mobile devices. Phishing attacks are usually platform independent and, therefore, trigger from most any email client or application.
  • Protect your email with an independent advanced threat protection (ATP) service. ATP covers inbound and outbound traffic.  ATP uses pre-analysis and testing of links and attachments for mismatched domains, copycat content, and malicious behavior. This “sandboxing” lets the ATP service block attacks from reaching your inbox.
  • Add a DNS and Web Protection solution to your environment.  Web protection blocks infected or fraudulent web sites, including blocking malware on infected sites we trust. DNS protection prevents hackers from corrupting and using your domain identities.
  • Deploy backup/recovery and continuity services that protect your on-premise and cloud data. Should an attack make it through your protections, you should be able to keep your business running while you clean up the damage.

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
