Experts predict ransomware attacks will become more common in 2023, threatening to reveal valuable data from individuals and corporations if ransom demands are unmet.
They also expect to improve social engineering techniques used in scam attacks that prey on fears about the energy crisis and financial difficulties. As open-source software becomes more widely available and cybergangs enlist hacktivists for their campaigns, experts predict an increase in hostile behaviour overall.
Successful ransomware attacks, according to digital security firm Avast, can quickly escalate to millions of dollars in recovery costs for businesses due to a halt in operations, the need to reimagine devices and implement incident response plans, as well as operational costs from hospitals being unable to perform operations or factories ceasing production.
Businesses infected with ransomware may face difficulties if they comply with demands made by organisations on sanctions lists, such as Russian-based ransomware groups because they risk prosecution. This is due to new international sanctions enacted this year.
Avast researchers further predict the already professionalised business of cybercrime will become more sophisticated. Cybercrime groups Zloader, Racoon Stealer, and Ursnif came together this year to take advantage of each group’s specialisations and focuses on supporting one another and maximising profits. Avast researchers anticipate this kind of cross-group collaboration to continue.
Ransomware attacks themselves are already an individual’s and businesses’ nightmare. This year, we saw cybergangs threatening to publicly publish their targets’ data if a ransom isn’t paid, and we expect this trend to only grow in 2023,” said Michal Salat, Threat Intelligence Director at Avast.
“This puts people’s personal memories at risk and poses a double risk for businesses. The loss of sensitive files and a data breach can have severe consequences for their business and reputation.”
For businesses, successful ransomware attacks can quickly ramp up to millions of dollars in recovery costs caused by a pause of operations, reimaging devices and incident response programs, and operational costs, with hospitals unable to conduct surgeries or factories halting their production. New global sanctions introduced this year could put businesses affected by ransomware in a sticky situation, as they face potential prosecution if they pay ransom demands to groups listed on sanctions lists, for example, ransomware groups based in Russia.
“We’ve been living in a scamdemic for some time now, and there are no signs of a slow-down,” said Salat. “Cybergroups go to many lengths to tap into people’s worst fears to deceive them into sending money or giving up personal data because it is easier to make people vulnerable than hacking their devices. Next year, we expect to see attacks playing with people’s economic and environmental concerns. Scams are not just flooding people’s inboxes in the form of phishing emails, but are bombarding people’s text messaging apps, and are keeping their phones ringing.”

How people can protect themselves against scams
- If you have one, rather pay with a credit card. Compared to debit cards and bank transfers, credit cards are far more secure. Your credit card company is on your side when it comes to fraud. When you’ve been ripped off, chargebacks are your friend.
- Never download attachments or click links from unknown contacts. Scammers can use attachments and websites to infect your computer with malware. For example, trojans often slip onto your device while disguised as harmless attachments, and those Trojans can then bring rootkits, spyware or adware with them. Some malware will just show you ads, while others can be far more damaging.
- Keep personal information to yourself. You know how many websites ask you to answer a series of security questions in case you need to recover your password? Remember which information you’ve set as security measures, and don’t share it. Otherwise, scammers can answer your security questions with ease. Of course, this also applies to things like login credentials and account numbers.
- Secure yourself online. If a website offers two-factor authentication, use it. It’s not bulletproof, but it’s better than nothing. Use strong, unique passwords on the websites you frequent, and store them more securely with a dependable password manager.
How to help to prevent ransomware
- Keep your software updated. Making sure your OS and apps get new updates as soon as they’re released will plug security holes and prevent hackers from using exploits to deploy ransomware.
- Back up your system regularly. Ransomware typically gains its power from blocking access to important files. If you have the files backed up safely elsewhere, your chances of losing them to ransomware are reduced. Perform regular backups of your system and files — cloud services and physical storage are both viable options, and you should use both if you can. If your device lets you set an automatic backup schedule, do that as well.
- Use an ad blocker. Load up your browser with an ad blocker to shield yourself from malvertising and drive-by-downloads: two ad-related ways ransomware can make its way into your system.
- Be skeptical. Be wary of strange links sent in emails or on other messaging platforms. Even if the link comes from someone you know, they could have been hacked. Learn the signs of unsafe websites and avoid visiting them.
- Use an antivirus. Ransomware can hurt you only if it can reach you. Employ a robust cybersecurity app that helps blocks malware and viruses before they can get anywhere near you. Avast One helps block unsafe links, sketchy downloads, and unsecure websites.
