Security Advisory

The popular Foscam C1 webcam has multiple vuln erabilities that, if exploited, allow retrieval of information stored in the camera and the running of arbitrary commands in it's operating system.

A compromise of these wireless cameras is particularly disturbing when you consider they are frequently used as baby monitors and home security. Apps for computer and phone provide ready access to the camera, which captures both 720 HD video and 2-way audio. Data is stored on micro-SD cards, NVR, NAS, local hard drive, or in Foscam’s Cloud, and can also be sent with FTP.

Cisco's Talos Intelligence Group worked with Foscam to understand and resolve 20 separate issues, and Foscam has released an update to it’s firmware, version V-2.x.2.46, that patches these vulnerabilities in several of their cameras, and can be downloaded from:

The vulnerabilities and exploits include:

  1. Dynamic DNS allows running admin commands in camera with authority, and when a response string is longer than the response buffer, the extra characters can be executed by the camera as code.
  2. Un-signed “custom” Firmware Updates can be installed through the web interface, which lacks security and validation of the firmware image’s authenticity and integrity.
  3. Private camera information (MAC address, camera name, firmware version) can be obtained using unsecured UDP for device to device communication.
  4. If a username is entered that is longer than the receiving buffer in the camera, the extra characters can be executed as code by the camera’s operating system.
  5. User accounts in camera can be reset to factory defaults by an un-authenticated user in the web management interface.
  6. Even when logging off the web management interface, if the interface submits too long a string to the “logOut” command in the camera, even the limited but authenticated “visitor” account can cause the camera to run the extra characters as program code.
  7. These cameras are designed to communicate with a network gateway for remote access to the device through the web management interface using UPnP Discovery and Response. If the web interface sends a UPnP response that has more characters than the receiving buffer is expecting, the extra characters can be run as program code.

It is clear that the coding practices of programmers can introduce multiple vulnerabilities just waiting to be discovered. The companies releasing e-devices often release firmware updates when vulnerabilities are discovered or exploits are reported. When you purchase a new device, be sure to register it, save a bookmark to the Support page for your device, and sign up for email alerts when updates are released.

Layers of Security

IT Security today is like an onion with concentric layers of protection, where each layer must be compromised to get to the center. The military calls this "deep defense", as multiple defensive layers work together to deflect or slow down an attack.

Next generation firewalls remain your first line of defense with monitoring, content filtering, intrusion prevention, and 2 factor VPN access. Active Directory and Group Policy enforce consistent rights management that enables employees to work with the data they need, but protects the data they don't need. Modern cloud and client/server apps encrypt data in transit. Antivirus software and operating system patches protect both servers and end-user devices. Organizational policies, procedures and backups protect against and respond to threats.

We recommend:

  1. Design and periodically review IT security strategy with certified specialists.

  2. Cisco Meraki or ASA 5506X Next Gen Firewall, with annual subscription for content filtering and intrusion prevention.

  3. Dashboard managed end-point protection software on company-owned PCs, tablets and smart phones.

  4. LeeShanok's Managed IT or Hosted plans, where we design role-based access to your network and data, and enforce it through Active Directory and Group Policy.

  5. SSL VPN two-factor authenticated remote access to network.

  6. Modern supported operating systems patched with the latest security updates.

  7. VoIP and Video over IP communications need to be encrypted and secured too.

  8. Local and cloud backup of servers and data repositories that can spin up quickly following disaster.

  9. Physically locking server rooms, and automatic screen locking of PCs and phones.

Tips and Tricks

Monsoon Image

  • Shorts and Damage from WATER.
  • POWER Surges and Outages.
  • Failure from Excessive HEAT.
  • WATER - In your utility room, look for gaps between floor, walls, and ceiling, and around conduit entry paths and terminations. Water will follow cables into rack-mounted and free-standing devices, then seek low points on the floor to pool. Being a good conductor with little resistance, water lets big current flow where it shouldn't, zapping anything in it's path.

    Use Silicone based sealer to fill gaps in walls and around conduit and cable terminations. Patch roof coatings and gaps around flashing now to stop water on it's way to Arizona.

    POWER - Spikes, shorts, lows and outages cause unplanned shutdowns and can damage electronics and data. Uninterruptible power supplies (UPS's) condition lines against low voltage brownouts and power outages, which can spike when power returns. If power remains off, the UPS can initiate normal shutdown and avoid data loss. Check UPS batteries using monitoring software or dashboard. Make sure power capacity supports what's plugged in: Servers can require 1500 VA, Desktop PC's 600 VA, Switches/Routers/Firewalls 350 VA.

    If you haven't checked your backups in a while, now is a good time. Review logs for frequency and successful completion, then restore a few test files and folders. If you're not sure, create a new full backup before the first storm hits. We're here if you need help.

    HEAT - Monsoon storms are accompanied by excessive heat. As dust accumulates inside enclosures and airflow around components slows down, it's like wearing a heavy jacket on a summer day with little wind. It won't take long to exceed your comfort zone. Most electronic components have built-in temperature limits that cause rapid shutdown to avoid damage. The best prevention is adequate airflow around the devices in a relatively dust-free environment, with all internal fans working well. Don't forget annual device cleanouts. Monsoon storms can be dramatic, but these tips can help protect both network and data.

Data Breach

Two years ago on September 15, 2015, Experian discovered a massive data breach that exposed sensitive personal data of 15 million people who had applied for service with T-Mobile. Fast forward to 2017, and the personal information of 143 million Americans was exposed from May through July. As we have little say in the collection of our personal information by the credit agencies, there are several things all American's should do now.

  1. Visit and bookmark the following websites:

  2. Freeze Your Credit

    A credit freeze makes it harder for someone to open a new account in your name, but won't prevent a thief from making charges to your existing accounts.

  3. Place a Fraud Alert on your files:

    A fraud alert warns creditors that you may be an identity theft victim and that they should take steps to protect you

Tips and Tricks

When you leave home, you lock the door or close the garage. When you walk away from your computer, do you lock the display? Probably not.

In Windows 10, your display automatically locks after 10 minutes, which gives plenty of time for open windows to be inspected. One touch of the mouse or keyboard and the screen lock timer resets, providing another 10 minutes. It doesn’t take long for someone to run a search and email the findings off-site or upload them to a cloud account. They may connect a browser to a risky website or delete important folders.

Even a quick trip to the coffee station can be interrupted by a crisis that delays your return. When unattended, all computers should be:

  • Off
  • Asleep
  • Display off and computer locked

Don’t have time to lock your computer? Try this:

Some industries have serious compliance regulations and penalties. This policy protects you and your employer, customers and suppliers.

Security Advisory

On June 27 the US Government became aware of new ransomware called Petya.

Similar to WannaCry, it didn't require any user involvement, but infected through operating system vulnerabilities. It's demand for ransom in exchange for decryption key was a hoax, as encryption of Master Boot Records cannot be undone. Infected drives became unreadable and computers became un-bootable and any ransom paid was lost.

Recommended prevention steps:
  1. Protect end-point Windows devices with antivirus/antimalware software from respected providers (we recommend Trend Micro). Make sure subscriptions haven't expired. Central purchasing and administration allows for consistent protection and alert handling.
  2. Apply operating system and device patches (especially MS17-010) and updates to both Servers and end-user computers. It's true that updates occasionally cause problems. But vulnerabilities in unpatched systems increase over time.
  3. Apply updates to web browsers, Adobe Reader and Flash, Java, and other software regularly.
  4. Back up servers and file shares regularly, and periodically validate whether backups were effective. The date, time, and status should be reviewed for success. Try to extract several folders and files from backup sets. Ideally, disaster recovery and business continuity solutions are in place that synchronize continuously and can spin-up a server identical to the moment it failed. LeeShanok offers BDR and BC solutions that are effective and affordable.
  5. Make sure end users store data files on Shared Drives so they are included in backups.
  6. Protect end-user computers with active firewall software.
  7. Periodically review your network firewall. Businesses need a modern commercial grade device. Those with business centers or wifi for guests need filtering of malicious and illegal content, and traffic shaping. We recommend Cisco Meraki and Cisco ASA with FirePower. Make sure firmware updates are current.
  8. Host a security policy meeting for employees and satellite offices. Partner with LeeShanok's team as you prepare. To help you, we offer a 45 minute presentation called "IT Security for the Common Worker", also available via webinar.
  9. Many of these checklist items are managed by LeeShanok as part of our Managed IT and Hosted service plans.

Windows Vista – Support Ends

On May 12, 2017 "WannaCry" malware began exploiting a vulnerability in most versions of Windows dating back to XP. A month earlier, Microsoft identified the risk and responded with a patch (Critical Security Bulletin MS17-010) that required rebooting after installation. Many servers and end-user pcs were left vulnerable in more than 150 countries.

The malware sneaks through SMB ports, then encrypts a user's data and presents a growing ransom demand, starting at $300 and growing to $600, after which the garbled data is lost forever without a valid external backup. Once active it spreads quickly to other PCs in the same network.

Solution: Apply Security Update patch for Microsoft Windows (4013389). A restart will be required to complete the update.

Workaround: Disable SMBv1 on client and server computers, but do not disable SMBv2 or v3. Additionally, block SMB ports (139, 445) from all externally accessible hosts. A restart will be required to complete the workaround.

Our Customers

Hosted - Your servers and workstations have been patched.
