 Malicious PowerShell 

Attack sequences that exploit the ever-popular PowerShell are broadly attractive to top cybercriminals and cyberespionage groups because they make it easy to propagate viruses across a network. Notorious bad actors such as APT29 (aka Cozy Bear) use PowerShell scripts to gather critical intelligence to inform even more sophisticated cyberattacks. In 2020, the notorious threat group APT35 (aka “Charming Kitten”) abused Powershell in a ransomware attack on a charity organization and to harvest and exfiltrate data from a U.S. local government.

What you need to know: PowerShell is a command-line and scripting tool developed by Microsoft and built on .NET (pronounced “dot net”), that allows administrators and users to change system settings as well as to automate tasks. The command-line interface (CLI) offers a range of tools and flexibility, making it a popular shell and scripting language. Bad actors have also recognized the perks of PowerShell — namely, how to operate undetected on a system as a code endpoint, performing actions behind the scenes.

Compromised Credentials

 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...
