Masquerade Attack

 Masquerade Attack 

Many of us still remember when Target experienced a massive credit card breach affecting over forty million customer accounts. The states’ investigation into the breach revealed that attackers stole the credentials of Target’s HVAC contractor, Fazio Mechanical Services. After using the third-party vendor’s details to get into Target’s internal web application, they installed malware on the system and captured names, phone numbers, payment card numbers, credit card verification codes and other highly sensitive information.

What you need to know: A masquerade attack happens when a bad actor uses a forged or legitimate (but stolen) identity to gain unauthorized access to someone’s machine or an organization’s network via legitimate access identification. Depending on the level of access the permissions provide, masquerade attacks could give attackers access to an entire network.

 Compromised Credentials  In 2020, Marriott International suffered a massive data breach as a result of a compromised credentials attack. This breach compromised the accounts of 5.2 million Marriott customers, exposing their contact information, gender, date of birth and loyalty account information. The attacker used the login credentials of two Marriott employees, presumably obtained through a mix of phishing and credential stuffing, to collect Marriott customers’ information for an entire month before raising suspicion. What you need to know: Most people still use single-factor authentication to identify themselves (a pretty big no-no in the cybersecurity space). And while stricter password requirements are starting to be enforced (like character length, a combination of symbols and numbers, and renewal intervals), end users still repeat credentials across accounts, platforms and applications, failing to update them periodically. This type of approach makes it easier for adv...

SQL Injection

 SQL Injection  Structured Query Language, or SQL (sometimes pronounced “sequel”), is the standard programming language used to communicate with relational databases — systems that support every data-driven website and application on the internet. An attacker can take advantage of this (very common) system by entering a specific SQL query into the form (injecting it into the database), at which point the hacker can access the database, network and servers. And SQL injection attacks continue to be a popular attack method. As recently as August of 2020, the Freepik Company disclosed a data breach impacting the logins of more than eight million users resulting from an SQL injection in a global database of customizable icons, which allowed the hackers to access and ultimately steal user login and personal information. What you need to know: SQL injection is a type of injection attack used to manipulate or destroy databases using malicious SQL statements. SQL statements control the...
