Ransomware Makes News Again!

Everyone has now heard of ransomware, but to give a bit fuller background, this kind of malicious software is delivered into an information system—such as a computer or a database—and then renders all of the information inaccessible.

A dropper is a small helper program that facilitates the delivery and installation of malware.

Spammers and other bad actors use droppers to circumvent the signatures that anti-virus programs use to block or quarantine malicious code. It’s much easier to change the dropper, should its signature become recognized, than it would be to rewrite the malicious code-base.

Droppers, like many of their larger Trojan horse counterparts, can be persistent or non-persistent. Non-persistent droppers install malware and then automatically remove themselves. Persistent droppers copy themselves to a hidden file and stay there until they complete the task they were created for.

Droppers can be spread many ways, including by:

  • Opening an infected e-mail attachment.
  • Picking up a drive-by download on an infected website.
  • Clicking a malicious link on a website or in an email.
  • Using an infected flash drive.

Sometimes droppers are bundled with free utility programs (such as ad blockers) to avoid detection. When the free program executes, the dropper will first download and install malware before it unpacks and installs the legitimate utility.

Protect your data from insider threats

When it comes to protecting your Data and Network assets, Organizations continue to spend an exceptional amount of time and money to secure from external attacks; however, insider threats are becoming a key cause of data exposure. Based on survey from Small Businesses security experts have found that insider incidents account for more than 60 percent of all data breaches; however, many organizations don’t report insider attacks out of fear of business loss and damage to their reputation.  

Insider threats come in two forms. An authorized insider threat is someone who misuse their rights and privileges, either accidentally, deliberately or his credentials were stolen. An unauthorized insider is someone who has connected to the network behind the perimeter defenses. This could be someone who plugged into a jack in the lobby or a conference room, or someone who is using an unprotected wireless network connected to the internal network. Insider attacks can lead to data loss or downtime, so it is as important to monitor activity in your network as activity at the perimeter.  To have effective Network Security strategy, first, identify the main threats that your company currently faces. 

Historically, the data breaches that make the news are typically carried out by outsiders. Outsider threats are generally the threats that have been addressed with traditional security measures. It’s the threats that originate from inside that are much more difficult to prevent and detect using one-size-fits-all security measures.
