What Are Cyber Threats and What to Do About Them
At such times, the organization must take the necessary steps without delay. When this happens, catering to the incoming requests becomes overwhelming for the servers, resulting in the website it hosts either shut down or slow down. Use an Intrusion detection system, as they design it to detect unauthorized access to a network. This results in the attacker being able to view, edit, and delete tables in the databases. Update your passwords; this will limit your exposure to a password attack. Just a reminder that this is not an exhaustive list and that the OWASP Top-10 list should be read as well.
When a tech vendor discovers a security flaw in their product, they typically write code that fixes or “patches†the problem. Nation-states are the sources of many of the most serious attacks. There are several different versions of nation-state cyber threats. Some are basic espionage— trying to learn another country’s national secrets. Motives for data breaches include crime (i.e. identity theft), a desire to embarrass an institution (e.g. Edward Snowden or the DNC hack), and espionage.
The Informatic Directorate of the Greek Parliament identified an attempt to hack into 60 parliamentary email accounts.

From this initial access, cybercriminals can go on to achieve different objectives including malware infections, ransomware, denial of service attack, data theft, and more. A cyberattack occurs when cybercriminals try to gain illegal access to electronic data stored on a computer or a network. Cyberattacks can target individuals, groups, organizations, or governments.

Cyber attackers often use a flood attack to disrupt the “handshake†Security process and carry out a DoS. Several other techniques may be used, and some cyber attackers use the time that a network is disabled to launch other attacks. A botnet is a type of DDoS in which millions of systems can be infected with malware and controlled by a hacker, according to Jeff Melnick of Netwrix, an information technology security software company.
The U.S. Treasury Department’s Office of Foreign Assets Control attributed the March 29 hack of Ronin Network to a North Korean hacking group and announced sanctions against the hackers.
