DoS Attack

 DoS Attack 

Almost two decades ago, a 16-year-old hacker known as Mafiaboy launched one of the most famous denial-of-service (DoS) attacks that took several major sites offline, including CNN, eBay, Amazon and Yahoo. According to reports, Mafiaboy broke into dozens of networks to install malware designed to flood targets with attack traffic. Because many sites were underprepared for such an assault, the attack lasted about a week as the targeted organizations struggled to figure out what happened and how to get back online. Mafiaboy was eventually arrested and sentenced to juvenile detention. Twenty years later, DoS attacks (many of which are DDoS) continue to be on the rise and are some of the most common attacks faced by organizations, targeting around a third of all businesses.

What you need to know: A DoS attack is where cyberattackers make a machine or network inaccessible for its intended users. DoS attacks can be executed by either flooding networks with traffic or by sending information that triggers a system slowdown or complete crash. As with DDoS attacks, DoS attacks tend to focus on highprofile organizations or ones with popular, public-facing websites such as banking, ecommerce, media or government institutions. DoS attacks deprive legitimate users of the service they want to access and cause extensive damage to the victim, due to security and cleanup costs, loss of reputation, loss of revenue and customer attrition

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...
