In terms of mobile security, most of the best practices are easy for everyone to apply: install apps only from official stores (Google Play Store for Android, App Store for iOS), use a password manager, and always install quick updates to your apps and operating system.
But other practices are more difficult to follow. And one threat has plagued IT departments for years: Administrators have to constantly remind users not to do certain things. However, they keep coming.
If it’s your personal device, you won’t even be able to contact your IT department if something goes wrong. You will then have to go to your carrier and pay a fee to restore the device, which can be expensive, or to factory reset the device, which doesn’t always solve the problem. But if you’re a victim of ransomware, a factory reset will strip you of your data. Unless you’re willing to pay the ransom.
How to avoid this catastrophic scenario? I give you the most valuable advice: if you have any doubts, do nothing.
Curiosity is bad
I am regularly asked: “I received an SMS, but I do not know its sender. Can I click on a link? »
The answer, unequivocally, is always a resounding “NO”!
If you do not know the sender of an email message, SMS, WhatsApp or Facebook Messenger, or a message received through any other communication channel, do not open it, click on it, click on links, do not copy it. , don’t answer, don’t call the sender… in short, never interact with this stranger.
And therein lies the crux of the problem.
Many users and even some journalists blame the companies that supply operating systems and mobile applications for this. Not only does this not seem fair to me, but it is especially unnecessary. Just like on a computer, the user bears his share of responsibility. As far as I know, Google has never asked you to follow a link you received to unknown sources, and Apple does not threaten you to respond to this strange SMS.
And yet, despite repeated warnings, users still click on suspicious links and still reply to messages sent by strangers.
We remind you that the result can be disastrous for your data, your privacy and your identity.
Tons of messages every day
According to Avast, ransomware attacks have increased by 32% for businesses and 38% for individuals this year.
These attacks can take many forms: spoofed packet delivery, fraudulent technical assistance, sexual exploitation scams, or even phishing (gathering personal information with the intent of an attack or scam).
You have already received messages of this type. I receive them every day. At the time of this writing, I have received at least five similar scams.
This type of attack is so common that I have gone so far as to automatically block (or mark as spam) any email containing certain phrases or companies commonly used in scams.
Caution is the mother of safety
I also get about 10 text messages a day on my phone like, “Hi, I tried to call you, but you don’t answer. What happened ? » The sender of this message is not in my contact list, so I don’t know him.
For several years, I have developed a simple rule: I do not know the sender, I do not answer either the phone or the messages. I no longer hesitate to block and report these messages as spam. The sender may be legitimate, but I don’t risk it.
And this attitude of each user should be with his phone. Be careful and you will avoid many common attacks on your privacy and data.
