Credential Stuffing

Credential Stuffing 

Fort Lauderdale-based Citrix Systems found itself neck deep in investigating a major network breach in 2019 that had occurred the previous year, resulting in stolen business documents by hackers. The FBI believed the breach was sourced for “password spraying,” otherwise known as credential stuffing — an attempt by hackers to remotely access a large number of accounts at once. According to a form 10-K filing to the U.S. Securities and Exchange Commission, Citrix believed the hackers tried to infiltrate company systems to access content collaboration customer accounts.


What you need to know: With credential stuffing, cybercriminals will use stolen account credentials — often usernames and passwords procured from a data breach — to access additional accounts by automating thousands or millions of login requests directed against a web application. They want to access sensitive accounts the easy way — by simply logging in. It works because they rely on people reusing the same usernames and passwords across multiple services. If they’re successful, one credential can unlock accounts that house financial and proprietary information, giving them the keys to almost everything.

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 adversaries

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 database

Social Engineering Attack

-
 Social Engineering Attack  The 2002 film “Catch Me If You Can” tells the true story of (perhaps) one of the most accomplished practitioners of social engineering of all time. In the film, Leonardo DiCaprio portrayed a man named Frank W. Abagnale, Jr., who executed various high-profile cons, committed bank fraud and masqueraded in a variety of personas, including as a physician and pilot. Abagnale’s success depended on his ability to convince his victims that his forgeries, whether they were checks, diplomas or identities, were genuine. Abagnale was an active con man in the ‘60s and ‘70s, but the practice of social engineering has continued to develop and remains a powerful tool for hackers and fraudsters to gain access to closed systems around the world. What you need to know: Social engineering is the term used for a broad range of malicious activities accomplished through psychological manipulation to trick users into making security mistakes or giving away sensitive information.
