What Are Cyber Threats and What to Do About Them
It was conducted by APT 29, an organized cybercrime group connected to the Russian government. Another alarming statistic is that public companies lose an average of 8% of their stock value after a successful breach. Computer emergency response teams are set up by governments and large organizations to handle computer security incidents. It was the most significant cybercrime attack on an Irish state agency and the largest known attack against a health service computer system.
It does this using dedicated network equipment, deployed on-premises by the organization, or as a cloud-based service. Only cloud based services are able to deflect large scale DDoS attacks, which involve millions of bots, because they are able to scale on demand. WAFs can block malicious traffic before it reaches a web application, and can prevent attackers from exploiting many common vulnerabilities—even if the vulnerabilities have not been fixed in the underlying application. It complements traditional firewalls and intrusion detection systems , protecting attacks performed by attackers at the application layer . Man-in-the-Middle attacks are breaches that allow attackers to intercept the data transmitted between networks, computers or users. The attacker is positioned in the “middle” of the two parties and can spy on their communication, often without being detected.
A whale-phishing attack is so-named because it goes after the “big fish” or whales of an organization, which typically include those in the C-suite or others in charge of the organization. These individuals are likely to possess information that can be Cyber valuable to attackers, such as proprietary information about the business or its operations. Reducing the risk of a cyber attack relies on using a combination of skilled security professionals, processes and technology. Man-in-the-middle, or MitM, where attackers secretly insert themselves between two parties, such as individual computer users and their financial institution.
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 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.
The majority of the customers targeted were U.S. based, working for IT companies or the government. The U.S. Department of Justice charged four Russian government employees involved in hacking campaigns that took place between 2012 and 2018. The hacks targeted critical infrastructure companies and organizations largely in the energy sector. The hackers sought to install backdoors and deploy malware in the operational technology of their targets.
Likewise, the personally motivated, such as disgruntled current or former employees, will take money, data or a mere chance to disrupt a company's system. Socio-political motivated attackers seek attention for their causes. As a result, they make their attacks known to the public—also known as hacktivism.
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.
