Man-inthe-Middle Attack

 Man-inthe-Middle Attack 

In early 2022, Microsoft discovered a phishing campaign targeting Office365 users. The attackers spoofed a phony 365 login page, gathering credentials for later abuse and misuse. To do this, the attackers used a Evilginx2 phishing kit — a man-in-themiddle (MITM) attack framework used for phishing login credentials along with session cookies, allowing bad actors to bypass two-factor authentication — in order to hijack the authentication process. Microsoft added in its blog post, “Note that this is not a vulnerability in MFA; since AiTM phishing steals the session cookie, the attacker gets authenticated to a session on the user’s behalf, regardless of the sign-in method the latter uses.”

What you need to know: The MITM attack, also known as adversary-inthe-middle (AiTM), sets up a proxy server that intercepts the victim’s log-in session, so that the malicious actor can act as a relay between the two parties or systems — thereby gaining access to and/or pilfering sensitive information. This type of attack allows a malicious actor to intercept, send and receive data intended for somebody else — or that’s not meant to be sent at all — without either outside party knowing, until it is too late.

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.
