Poison Attacks: A quick overview

Poison Attacks: A quick overview

Smart technology is everywhere. Not just in our offices, but even in our day-to-day lives with tools like Google Home and Alexa becoming a commonplace. With technology becoming smarter every minute, the risks are increasing by the minute as well. Cybercriminals are finding new ways to corrupt our IT networks to disrupt our businesses, hold our data hostage and even clear our personal bank accounts. Some of the more overt, commonly known acts of cybercrime include hacking, phishing, and ransomware attacks. This blog discusses a lesser-known cybercrime--Poison attacks.

What are Poison attacks
Poison attacks are attacks on the ability of the system to make smart decisions. Think about this. How do systems make intelligent decisions? Based on the training or data they receive. This data is used to hone the artificial intelligence of the system to help make smart decisions. Poison attacks mess the very base--the training data set. Poison attacks basically skew the system’s data model in such a way that the output is no longer as intended. They create a new normal for everything. Poison attacks are primarily backdoor attacks. In a backdoor poison attack, the attacker creates a loophole in the core data rule and trains the system to adhere to that rule so it can be exploited at a later time. For example, let’s say, the access control for a particular file is set such that it will allow only those beyond the VP level to view the data. If someone changes the main parameter to include manager level in there, the core data set is violated and the system will not detect an intrusion by someone at the manager level, even if they log in with their credentials.

Unlike Ransomware, poison attacks don’t make much noise but cause far more damage as they can go undetected for a longer time. Follow our blog next week as we discuss the 3 common types of poison attacks

Watch out for these poison attacks!
Poison hamper the ability of the system to make smart decisions by disturbing the very core data set that is used to make a decision. Poison attack methodologies typically fall into one of the following 3 categories.

  • Logic corruption
  • Data manipulation
  • Data injection
Logic corruption
In logic corruption, the attacker changes the basic logic used to make the system arrive at the output. It essentially changes the way the system learns, applies new rules and corrupts the system to do whatever the attacker wants.

Data manipulation
In data manipulation, as the name suggests, the attacker manipulates the data to extend data boundaries that result in backdoor entries that can be exploited later. Unlike logic corruption, the attacker doesn’t have access to the logic, so they work with the existing rule and push data boundaries further with a view to accommodate them later.

Data injection
In data injection, the attacker inserts fake data into the actual data set to skew the data model and ultimately weaken the outcome. The weakened outcome then serves as an easy entryway for the attacker into the victim’s system.

Understanding Managed Services and How They Benefit SMBs

Understanding Managed Services and How They Benefit SMBsSmall to medium sized businesses (SMBs) receive a lot of calls each day from slick sales people peddling the next technology trend that's going to save them money and revolutionize how they do business. They're all too quick to caution that if you don't listen to them, you'll fall behind the times, and eventually be swimming in a sea of debt and out of business.

No doubt you've heard, or you've at least read about, the benefits of managed services. Managed services refer to clearly defined outsourced IT services delivered to you at predictable costs. You know the exact IT services you'll be getting and what you'll pay for them. There is no surprise sky-high bill for services rendered. So are solicitation calls that pertain to managed services worth listening to? We think so. Then again, we're in the managed services industry. There may be a bit of a bias here.

Be Proactive: How to Avoid Potential Network Failures

Be Proactive: How to Avoid Potential Network FailuresFor small- to medium-sized businesses (SMBs), an IT network failure can be devastating because they don't have the resources of large corporations to bounce back from such disasters. Preparation against such devastation may be the only course for them to avoid failure and survive with the least damage if failure occurs. SMBs must be proactive in recognizing the eventuality of a cyberattack or human error that can cause data loss and disrupt business continuity. This is what needs to be done to help prevent a potential failure.

Be prepared: Being proactive is an essential step for preparation against a disaster. There are two ways to determine how to best prepare to prevent potential failure of your infrastructure. First, you need to identify the weaknesses throughout your systems, and second, determine how you are going to eliminate those weaknesses and protect your network.

Identify the weaknesses: Determine how and why your syst…

Loss of Data: Causes and Prevention

Loss of Data: Causes and PreventionThe adoption of technology from the simplest of matters to the most complex problems has rendered us heavily dependent on it. We love paying our bills minutes before they are due. We enjoy seeing loved ones face-to-face on our computer screens. We can access and print our extremely sensitive records from government and financial websites in a matter of minutes instead of waiting for the mail for days. The time and resources that technology saves are invaluable, but this convenience has a very ugly side. This convenience brings costs, which could include irreparable financial, professional, and social damage. The technology that is designed to make life easier can also wreak havoc when criminals use it to breach secured, personal information. So how do we tame this beast called 'breach of data security'?

Background: The gravity of the problem: To look for a solution, we first need to understand how serious this problem is. Breaches in data secu…
