When you think of hacking, you probably conjure images of lonely cyber geeks scrolling through lines of code trying to extort millions of dollars.
In reality, hackers tend to work in organized crime gangs and attack everyone, from people like you all the way up to governments and armies.
A hack can be anything from theft of your personal data and banking logins to someone encrypting your hard drive and demanding cash to fix it. There are plenty of different hacks and lots of ways you can figure out if you’ve fallen prey to them.
With so many types of hacking around, there are lots of signs you’ve been hacked to look out for. Here are some of the most common.
If you get a message on your screen telling you your device has been encrypted and telling you how and where to send a payment to fix it, it’s a clear sign you’ve been hacked.
It is possible to get a ransomware message when nothing bad has happened to your computer, but you should always proceed with caution. If you choose to pay the ransom, you probably won’t get all your data back anyways – only 4% of ransoms paid end up in full data recovery.
Getting a ransomware message can be scary, but if you create backups, often you should be able to recover most of your data without paying a dime.

A savvy tech user will have decent antivirus and antimalware software already installed. If you get a notification from a company you use, pay for, and trust telling you there is a problem with your computer or phone, take heed.
While dodgy pop-ups warning you of imminent data disasters are to be avoided, when you pay for a service to warn you there’s something wrong, then there probably is. Be sure to log into your account from a device that’s not included in the warning and follow the company’s instructions.
Clear notices and warnings are a pretty sure sign you’ve been hacked, but it’s not always so clear-cut. Hackers will try and get into your computer to find out your data to commit identity theft or break into your bank account, and if this is happening, your computer will go slower.
Does a simple website take forever to load? An app that was lightning-fast suddenly takes minutes to pull up your details? These could be signs that an unauthorized process is running on your device.
If this starts to happen, check through the processes running on your device and remove anything that shouldn’t be there. You may need to wipe your computer and start again in extreme circumstances.
It’s pretty common to get an email to confirm when you’ve changed your password on an online account. Getting this email when you’ve not actually tried to change your email should set off alarm bells.
Receiving two-factor authentication codes by SMS or email that you’ve not requested or getting an error message when trying to log in to an account, you’re sure you know the details for are also signs of trouble.
If you find your password has been changed for your social media, banking, or online shopping accounts, you should contact the company directly. They will have a process in place to help you recover and secure your account.
We all know what it looks like to search online – go to a search engine, type in your query, and get a list of matching results. When it starts to look different, you may have a problem.
Seeing the screen flash after you hit enter or going to a different-looking page could be a warning sign you’ve been hacked. This could be the start of someone watching your online activity in order to get your passwords and break into your banking or shopping accounts.
You can check if something looks not quite right by doing the same action in a different browser. If things are looking odd, you need to investigate deeper into your computer.
This warning could go one of two ways. First, if your friends and family tell you they’re getting emails and messages from you that seem out of the ordinary, something is wrong.
Hackers can use your details to try and get your contacts to reveal your personal information or even their own. They can also get into your phone or email account to harvest the details of people you know to try and extort money out of them – while pretending to be you.
You might also be the person who gets emails or messages pretending to be a loved one. If you’ve clicked on a link in a strange message, you could be on your way to being the next victim of a hack.

Using your phone and computer regularly means you know what it should look like – where to look for the apps and tools you use most. When something looks out of place, it’s a sign a hacker may have infiltrated your device.
Anything that you didn’t recognize installing, should be checked out immediately. Avoid accessing it, but check in your Settings when it was downloaded and how much processing power and data it’s using. This should give you a good indication of whether it’s something you’ve forgotten about or if a hacker is using it to track what you’re doing on your device.
All of these can seem pretty scary – losing access to your accounts, having your online life tracked and logged… There are steps you can take to prevent a hacker from getting into your device, which we’ve pulled together here for you.
Hacking comes in many forms – some can be super obvious, like a big red ransom demand on your screen, while others can be more subtle, like a weird-looking search result.
Know your usual routines and remember what things should look and feel like. When things get strange, you should start investigating what’s installed on your device and why it might be behaving differently.
Seek professional advice if you fall victim to a hack, including informing the police if you’ve lost money or been the victim of a scam.
There are websites that keep track of data leaks, such as when emails and passwords are stolen from companies by hackers. Your antivirus or VPN tools may also offer a similar service you can register with.
A popular site to check is Have I Been Pwned. Here, you can enter your email addresses, and it will check if it’s ever come up in a data leak. If it has, you can consider changing passwords for accounts associated with that email address.
Your first action will depend on the type of hack you’ve been exposed to. If you’ve given your security details or password away in a phishing attack, contact the company whose credentials you’ve given away and follow their processes.
When you get a ransomware notice, first, you should take a photo in case you need it later. Then, you should turn off your device and disconnect it from networks, so remove any SIM cards or internet cables. After that, you should seek professional advice about your next steps.
When someone has gotten into your emails and changed your password, you should be able to reclaim the account as long as you can access your phone or backup email address. Each email provider will have different processes for you to follow.
If your phone has been hacked and compromised, the first thing you should do is go through all of your apps and delete any that look unfamiliar. You can find a complete list of apps through your settings menu on Android or Apple phones.
Once everything suspicious is deleted, use your security software tools to scan your phone again. Check data usage and performance to see if there are still signs of a hacker being present. If all else fails and you can’t get rid of the hacker, you should back up as much of your data as possible and perform a factory reset.

To fight digital financial crime, you’ve got to know what you’re up against. You’ve got to identify risk and fortify. Prime vulnerabilities for digital theft need to be protected. The difficulty is, financial criminals are successful enough they’re able to run an entire industry. The “black hat”, “cybercriminal” industry generates comparable economy to “white hat” tech, worldwide.
There are a number of reasons for this, chief among them tech companies that base their entire revenue generation model around digital theft, scams, and similar activities. We’re all familiar with the trope of a scammer based in Mumbai, or a similar city, using the lack of information certain people have to trick them into giving up their assets.
There are tax scams and those which deceive targets into believing they’ve been paid money they shouldn’t have. Quite a variety of tactics exist. What’s relevant to business clients is that cybercriminal financial crime often targets small and large operations in similar ways. Phishing scams are a fine example. Artificial Intelligence (AI) can act as a digital shield.
For example, adaptive contextual technology through NICE Actimize can be a key resource in preventing financial crime, such as money laundering. We’ll explore more ways AI helps prevent financial crime here.
Because many cybercriminal exploits function much like white hat technology through a traditional Managed Service Provider, or MSP, there is a high degree of automation going on. Scammers will set up programs and protocols designed to automatically seek out vulnerabilities in targets. Basically, they use their own form of AI.
As the old saying goes, it takes one to know one. Because cybercriminal revenue generation commonly utilizes automation which necessarily involves AI and Machine Learning (ML), using the superior, but similar, digital tactics is a fine way of anticipating their maneuvers and protecting your business against them.
AI and ML Applications Can Help You Know Where to Fortify
Where things get difficult is in terms of social engineering hacks, which in modern times often combine AI and ML cybercrime techniques with old school “con” jobs. Are you familiar with that classic film The Sting, or the newer caper drama Now You See Me, where magicians steal? Well, modern cybercrime incorporates such tactics as well as those related to tech.
A great example of a social engineering hack is a phishing scam wherein an email that is designed to appear as though it came from a “higher up” in the company is sent to those in the financial areas of an organization. The email will demand funds, information, access, or something else, and it will demand that information immediately.
Staff needs to be trained on how to avoid and anticipate such scams, but AI can look for features which could flag certain messages ahead of time. There are “digital sandboxes” where files sent via attachment through email can be accessed without compromising the whole network of your business. They can be “detonated”, as it were, safely.
Spelling, actual email addresses, the time emails are sent, and the like can be flagged, either preventing emails from being sent to an email server or notifying recipients that there is suspicious activity afoot. So you can use AI as leverage against social engineering hacks by identifying common features of such attacks and fortifying operations against them.

In a nutshell, proper AI and ML help you identify patterns, anticipate cybercriminal attacks, and fortify your business against financial crime overall. This is a brief overview, there are textbooks on this subject. In a nutshell, if you haven’t looked into AI security against cybercrime, this is a wise move.
