 Suspicious Zoom Child Processes 

Video-conferencing giant Zoom has emerged as the top enterprise video communications platform over the last several years. Its usage has increased dramatically with an upsurge of remote workers, attributed largely to shelter-in-place mandates following the COVID-19 pandemic. However, as Zoom’s popularity soared, flaws in both Windows and macOS systems have correspondingly received increased scrutiny by bad actors, who have increasingly relied on this attack vector to gain unauthorized access and escalate privileges onto targeted systems — including exploiting a local library validation function in Zoom to completely hijack an unsuspecting user’s webcam and microphone. Plausible attack scenarios could mean that attackers use their ill-gotten privileges to spy on targeted users, either in their personal lives or during important meetings where sensitive information is being shared.

What you need to know: Essentially, these local privilege escalation flaws take advantage of Zoom’s software architecture designs. These exploits can be launched by a local attacker, in which the adversary is someone who already has physical control of a vulnerable computer. Once the bugs are exploited, attackers can gain and sustain persistent access to various functions of a victim’s computer, which allows them to install ransomware, Trojans, spyware and numerous other types of malicious code into targeted systems for nefarious purposes.

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...
