Why SLTT Governments? (08:59)

  • Why are cybercriminals targeting me?

    • You are not targeted, it is bad luck
    • Cybercriminals are opportunistic
    • It is hitting you because your email was collected somewhere
    • Malware got in through your email or browsing
  • Criminals look for data and governments have a lot of it.

    • Licenses, certificates, bank details, taxes, all of which go through SLTT governments

 

Malware Trends (10:17)

  • Financial malware is the most common type
  • Network monitoring is tracked through signatures and patterns that are malicious and associated with specific types of malware.
  • Malwares detected during network monitoring for the month of September

    • Kovter (Trojan)

      • Trojan – hides what it is, gets into your network looking like an innocent file then it becomes malicious
      • Clickfraud – flash advertisement that pops up
      • Downloads Ransomware
    • Emotet (Banking)

      • Sends a spam email with macros in a Microsoft document
      • That is how they hide malware in a document
      • Scrapes names and email addresses in your contacts to spread it further
    • ZeuS (Banking)
    • Ursnif (Exploit Kit)
    • ElTest (Exploit Kit)

  • Most popular infection vector: Malspam
  • Common Tactics

    • Scraping address books
    • Sending spam
    • Stealing banking and social media passwords

      • Discuss what a ransomware infection would cost your specific agency and make decisions before infection occurs
      • Keep in mind – in 20% of cases, decryption keys do not work
      • Prepare and test protocols for multiple scenarios and have recovery plans in place
    • Prevention

      • Keep your systems patched – desktops and servers

    • MS-ISAC Recommendations

      • SLTTs should follow the guidance in the federal directive
  • BOD 18-01 on Email & Web Security

    • The federal government must take certain steps to ensure that emails are who they are sent from, to prevent spoofing.
    • Internet traffic to websites owned by the government use https – which is the secure protocol for internet traffic.

      • This ensures internet traffic to federal sites are encrypted by default
      • No one sees what you’re browsing or the information you’re sending

Q&A:

Would you recommend that first responder kind of organizations such as communications organizations, law enforcement agencies, that kind of thing, should they basically drill and train on what their procedures should be should they experience a cyber attack and their systems go down? (49:47)

Absolutely. It is such a critical environment that you need to be able to respond no matter what. It's really important to know what to do if you don't have a computer. These can shutdown dispatch, 911 access to the internet, you should know how to operate without a computer and still get the information you need to people who may be out in the field without any other connectivity device.

 

Are conference calls systems vulnerable? If so, is there a particular one you recommend for secure meetings? (51:09)

I cannot make recommendations like that (on providers) being a  DHS contractor.

 

Con-call systems can be vulnerable – yes.

 

If you're talking about a webinar system like we're using today. Webinar systems are transmitted over the internet, there is going to be some security, but these are not made to transmit classified information for a reason. A system like this is always vulnerable.

 

If you're talking about something like a Polycom, it is also vulnerable. Polycoms are in some ways just computer devices that happen to have a phone attached. They run over a voice-over IP, which means the data stream itself could potentially be vulnerable. The Polycom itself could have malware on it – I have actually seen this occur.

 

The easiest attack I have seen, occurred with a Polycom is when the agency did not switch its userID numbers for every new call. So once they gave out the call information, it was the same info used time and again – which meant if they had a call with you six months later, you can keep trying calling into that phone using the same guest ID and see if you will get through to a new phone call.
