Denial Of Service Attacks
This is when your business, personal website or IT system has come under some form of cyber-attack. Users are then unable to access the systems.
If you believe that you have been the victim of a Cybercrime, you can report it to Police Scotland.
NCSC have guidance to help organisations understand and reduce DoS attacks.
What Are The Two Main Defenses Against Ransomware
In addition to reducing your attack surface, a layered approach to security using antivirus software, firewalls, and multi-factor authentication is also an effective defense strategy that ransomware can thwart.
What is ransomware and how can it be prevented?
Ransomware attackers have ways to bypass cybersecurity measures, but they can protect your business. Tactics to reduce the risk of infection include backups, user training, quarantining suspicious emails, and content filtering.
What are the two main types of ransomware?
While there are innumerable types of ransomware, they mainly fall into two main types of ransomware. These are crypto ransomware and locker ransomware.
What Is Police Ransomware
Police is a malicious program classified as ransomware. This malware is designed to encrypt data and demand payment for decryption. During the encryption process, all affected files are appended with the “.Police” extension. For example, a file originally named something like “1.jpg” would appear as “1.jpg.Police” following encryption.
Once this process is complete, ransom messages are created in a pop-up window and “HOW TO DECRYPT FILES.txt” text files, which are dropped into compromised folders.
The ransom-demand message in the pop-up window and “HOW TO DECRYPT FILES.txt” files is identical. It informs victims that their files have been encrypted. To restore their data, they are to purchase decryption tools from the cyber criminals behind the infection.
The cost of the recovery tools is stated to be US$500 , however, if contact with the criminals is established within the first 72 hours, this can be halved to US$250. Communication is to be initiated via email. Users are warned that they have 70 attempts to enter the correct decryption code.
Should the number of attempts be exceeded, the files will be irreversibly damaged. Unfortunately, in most cases of ransomware infections, decryption is impossible without involvement of the cyber criminals responsible, unless the malware is still in development and/or has significant flaws.

Attacks On A Computer System
An attack on a computer system is any type of offensive act that targets computer data, information, infrastructure, network, cloud or any personal computer devices.
A computer attack can range from installing malware on a personal computer to crippling countries’ critical national infrastructure and can be conducted intentionally or recklessly and without authorisation, resulting in damaging, deleting, modifying, or otherwise interfering with or impairing any data or software in any computer system.
Below are some common types of cyber security attacks against computer systems:
- SQL Injection attacks
- Denial-of-Service attacks
- Brute-Force and Dictionary attacks

Is It Ethical To Pay Ransomware Demands
In the United States, paying the ransom is legal for now, but cybersecurity professionals advise business owners not to do so. According to the value of the assets, an organization may decide it must pay the ransom and that doing so is legal.
FBI agents have a greater understanding of the idea that businesses shouldn’t pay ransom money. They say doing so only exacerbates the problem.
In some situations, it might be in a company’s best interest to pay the ransom. But experts recommend telling the feds or the National Cybersecurity Agency. You can also report it to the Infrastructure Security Agency instead.
What Do Public Agencies Like Fdic Or Uk Gchq Generally Mandate Organizations To Report After Becoming Aware Of A Breach
Data breach notification laws vary based on location and industry. In the United States, the Federal Deposit Insurance Corporation requires banks to report an incident that has or is likely to affect the banks operations, services, or the financial sector no more than 36 hours after they have determined the breach occurred. They are also required to notify their customers as soon as possible if the breach will affect those customers for more than four hours. All banks must comply with these new data breach notification requirements by May 1, 2022.
Reporting in the United Kingdom is governed under the UK General Data Protection Regulation . Under the UK GDPR, all organizations must report a data breach within 72 hours of determining a breach has occurred. Also within the United Kingdom, the National Cyber Security Centre provides advice and support to organizations on how to address cybersecurity threats both through data security and data protection measures to mitigate malware and ransomware attacks.

Ransomware May Steal Your Data
I have mentioned that a lot of victims are underestimating the possible hazard, thinking that they can deal with the problem without help from authorities. Ransomware developers likely decided to put these self-confident characters down and started to distribute ransomware together with spyware.
Spyware is a type of virus that steals different sorts of data from your computer. Passwords, logins, banking app credentials, personal information, private conversations, corporate documents that are about to be kept away even from the personnel of this company all these things are not private anymore. The first case when a ransomware attack was combined with a data leak happened a year ago, in January 2020. Maze ransomware developers asked for a separate ransom to be paid to delete the information they stole. Later, the private information of the victims that ignored this offer was published on the website in darknet2. Do you still think that it is a good idea to deal with this problem independently?

Ransomware is often spread through phishing emails with malicious attachments or drive-by downloads. Drive-by downloads occur when a user unknowingly visits an infected website and then malware is downloaded and installed without the users knowledge.
Who was behind the Kaseya attack?
Who is responsible? The cyberattack was attributed to the ransomware group REvil / Sodinikibi, which held responsible on its dark web leak site Happy Blog. In an update over the weekend, the operators allegedly linked to Russia claimed to have infected more than one million systems.
Who created ransomware virus?
Popp . It was called the AIDS Trojan, also known as the PC cyborg. Popp sent 20,000 infected disks labeled AIDS Information Introductory Diskettes to participants at the World Health Organizations international AIDS conference in Stockholm.

New ransomware variants are emerging regularly. Cyber security companies reported that in the first several months of 2016, global ransomware infections were at an all-time high. Within the first weeks of its release, one particular ransomware variant compromised an estimated 100,000 computers a day.
Ransomware infections impact individual users and businesses regardless of size or industry by causing service disruptions, financial loss, and in some cases, permanent loss of valuable data. While ransomware infection statistics are often highlighted in the media and by computer security companies, it has been challenging for the FBI to ascertain the true number of ransomware victims as many infections go unreported to law enforcement.
Victims may not report to law enforcement for a number of reasons, including concerns over not knowing where and to whom to report not feeling their loss warrants law enforcement attention concerns over privacy, business reputation, or regulatory data breach reporting requirements or embarrassment. Additionally, those who resolve the issue internally either by paying the ransom or by restoring their files from back-ups may not feel a need to contact law enforcement.

Identify The Ransomware Infection:
To properly handle an infection, one must first identify it. Some ransomware infections use ransom-demand messages as an introduction .
This, however, is rare. In most cases, ransomware infections deliver more direct messages simply stating that data is encrypted and that victims must pay some sort of ransom. Note that ransomware-type infections typically generate messages with different file names . Therefore, using the name of a ransom message may seem like a good way to identify the infection. The problem is that most of these names are generic and some infections use the same names, even though the delivered messages are different and the infections themselves are unrelated. Therefore, using the message filename alone can be ineffective and even lead to permanent data loss .
Another way to identify a ransomware infection is to check the file extension, which is appended to each encrypted file. Ransomware infections are often named by the extensions they append .
This method is only effective, however, when the appended extension is unique – many ransomware infections append a generic extension . In these cases, identifying ransomware by its appended extension becomes impossible.
One of the easiest and quickest ways to identify a ransomware infection is to use the ID Ransomware website. This service supports most existing ransomware infections. Victims simply upload a ransom message and/or one encrypted file .
