What Is Cyber Attacks
A cyber attack is an attack that is mounted against us by means of cyberspace. Cyberspace, a virtual space that doesn’t exist, has become the metaphor to help us understand digital weaponry that intends to harm us. Best practices to help prevent an IoT attack include updating the OS and keeping a strong password for every IoT device on your network, and changing passwords often.
A Trojan horse attack uses a malicious program that is hidden inside a seemingly legitimate one. When the user executes the presumably innocent program, the malware inside the Trojan can be used to open a backdoor into the system through which hackers can penetrate the computer or network. This threat gets its name from the story of the Greek soldiers who hid inside a horse to infiltrate the city of Troy and win the war.
National Security Agency of engineering a backdoor to monitor companies and governments in over 45 countries around the world. Hackers targeted the Telegram accounts of Ukrainian government officials with a phishing attack in an attempt to gain access to the accounts. Russian hackers targeted the Costa Rican Ministry of Finance in a cyberattack, crippling tax collection and export systems. The newly elected President of Costa Rica declared a national emergency as a result of the attack and the group asked for $20 million in ransom or it plans to leak the stolen data. We focus on cyber attacks on government agencies, defense and high tech companies, or economic crimes with losses of more than a million dollars.
In the U.S. alone, the average daily volume of transactions hit $3 trillion and 99% of it is non-cash flow. To be able to disrupt that amount of money for one day or for a period of days can cause lasting damage making investors pull out of funding MFA and erode public confidence. A cyberattack against the United Nations occurred in April 2021, targeting users within the UN network to further long-term intelligence gathering. The hacker was able to access their networks through stolen user credentials purchased on the dark web.
Once they’ve hijacked a session, hackers can do anything the client’s account could do. For example, let’s say you’re accessing your company’s internal database while on a work trip. If a hacker hijacks your session, they’ll gain access to all of your company files.
Cyber security practices continue to evolve as the internet and digitally dependent operations develop and change. According to Secureworks, people who study cyber security are turning more of their attention to the two areas in the following sections. Cyber security professionals should have an in-depth understanding of the following types of cyber security threats. Malware is a general term for malicious software, hence the “mal” at the start of the word. Malware infects a computer and changes how it functions, destroys data, or spies on the user or network traffic as it passes through.
The actor responsible is still unknown, but the cyberattack led to the government extending voting by two days. The Lithuanian Defense Ministry found hidden features in popular 5G smartphone models manufactured in China, according to its state-run cybersecurity body. The module embedded in the phones detects and censors 449 keywords or groups of keywords that are counter to the message of the Chinese government. Hackers leaked data and photos from the Israeli Defense Ministry after gaining access to 165 servers and 254 websites, overall compiling around 11 terabytes of data.
