“Suspicious login” scammers up their game – take care at Christmas

Black Friday is behind us, that football thing they have every four years is done and dusted (congratulations – spoiler alert! – to Argentina), it’s the summer/winter solstice (delete as inapplicable)…

…and no one wants to get locked out of their social media accounts, especially when it’s the time for sending and receiving seasonal greetings.

So, even though we’ve written about this sort of phishing scam before, we thought we’d present a timely reminder of the kind of trickery you can expect when crooks try to prise loose your social media passwords.

We clicked through for you

Because a picture is supposed to be worth 1024 words, we’ll be showing you a sequence of screenshots from a recent social media scam that we ourselves received.

Simply put, we clicked through so you don’t have to.

This one started with an email that pretends to be looking out for your online safety and security, though it’s really trying to undermine your cybersecurity completely:

Even though you may have received similar-looking emails from one or more of your online account providers in the past, and even though this one doesn’t have any glaring spelling or grammatical errors…

…if fact, even if this really were a genuine email from Instagram (it isn’t!), you can protect yourself best simply by not clicking on any links in the email itself.

If you have your own bookmark for Instagram’s help pages, researched and saved when you weren’t under any cybersecurity pressure, you can simply navigate to Instagram directly, all by yourself.

That way, you neatly avoid any risk of being misdirected by the blue text (the clickable link) in the email, no matter whether it’s real or fake, working or broken, safe or dangerous.

The trouble with clicking through

If you do click through, perhaps because you’re in a hurry, or you’re worried about what might have happened to your account…

…well, that’s when the trouble starts, with a fake page that looks realistic enough.

The crooks are pretending that someone, presumably someone enjoying a vacation of their own in Paris, tried to login to your account:

You ought to be suspicious of the server name that shows up in the address bar in this scam (we’ve redacted it here, though it wasn’t anything like instagram.com), but we can understand why so many users get caught out by fake domains.

That’s because lots of legitimate online services make it as good as impossible to know what to expect in your address bar these days, as Sophos expert (and popular Naked Security podcast guest) Chester Wisniewski explained back in Cybersecurity Awareness Month:

In this scam, whether you click [This wasn't me] or [This was me], the crooks take you down the same path, asking first for your username:

The wording has started to get a bit clumsy on the next screen, where the crooks are going for your password, but it’s still believable enough:

A fake mistake

The scammers then pretend you made a mistake, asking you not only to type in your password a second time, but also to add a tiny bit more personal information about your location:

Not every phishing scam of this sort uses the “your password is wrong” trick, but it’s quite common.

We suspect that the crooks do this because there’s dubious security advice still going around that says, “You can easily detect a scam site by deliberately putting in a fake password first; if the site lets you in anyway, then obviously the site doesn’t know your real password.”

If you follow this advice (please don’t – it only ever gives you a false sense of security), you might jump to the dangerous conclusion that the site must surely know your real password, and must therefore be genuine, given that it seems to know that you put in the wrong password.

Of course, the crooks can safely say that you got your password wrong the first time, even if you didn’t.

If you deliberately got your password wrong, the crooks can simply pretend to “know” it was wrong in order to trap you into continuing with the scam.

But if you’re sure you really did put in the right password, and therefore the fake error message makes you suspicious…

…it’s too late, because the crooks have already scammed you.

One last question

If you keep going, then the crooks try to squeeze you for one more piece of personal information, namely your phone number:

And to let you out of the scam gently, the crooks finish off by redirecting you to the genuine Instagram home page, as if to invite you to confirm that your account still works correctly:

What to do?

Left. Use ‘Privacy’ option on the Instagram Settings page to make your account private.
Right. Toggle the ‘Private account’ slider on.
