3 Ways to Avoid Olympic-Themed Malware and Scams

Earlier this week, F-Secure Labs found a malicious Olympic-themed PDF. So we thought this would be a good time to talk about a topic comes up whenever an event like the World Cup, a celebrity death or even a tsunami captures the world’s attention.

Online criminals know millions of us are bound to be obsessed with the Olympics. So they’re going to use our interest to lure us into doing dumb things we would not normally do.

Here’s what you can to do help avoid current event threats.

1. Be wary of any email or private message that includes attachments or links.
Everyone knows opening an email attachment you weren’t expecting is dangerous. However links in emails can easily lead to malicious attacks or scams. Be extra suspicious of any emails related to topical events and celebrities. If you must click the link, check it with Browsing Protection first. Also keep in mind that private messages in Twitter with links often lead to phishing scams. While these scams probably won’t lead to malware, they could end up with a very embarrassing spamming of all your friends and followers.

2. Keep your system patched and protected.
The Olympic-themed malicious PDF the Labs found relied on an exploit in older versions of Adobe Reader. Other attacks will use other exploits. This is why it’s crucial you keep your Adobe Reader, Java, browsers, operating system and security software updated. Our Health Check makes this easy on your PC.

3. If a message is about a current event or seems to good (or bad) to be true, pause for a moment.
If you are looking for information on breaking news use the Google News search when available. If you get an email from your bank or credit card company that seems odd, call your institution. If you get a message that says someone has been saying bad things about you, don’t click on the link. Because this is the Internet. Of course someone is saying bad things about you somewhere. Clicking on the link can only lead to bad things, like a scam.

Events like the Olympics bring the world together. With some savvy, you can enjoy the games without the trouble of a comprised computer.

Cyber Monday Mythbusting

It's Cyber Monday, and marketing companies expect online shoppers to flock to websites and apps in order to take advantage of holiday sales. And naturally, this causes concerns about what kind of risks people are taking when they shop online. But F-Secure Security Advisor Sean Sullivan says any security warnings focusing on Cyber Monday are simply part of the hype. “Cyber Monday is no more or less safe than any other day of the year. People just expose themselves to more online threats when they do more stuff online, but that really has nothing to do with Cyber Monday. And people that tell you otherwise aren’t doing you any favors.” So there you have it. On the other hand, Sullivan does point out that holiday shoppers should beware of the extent to which they expose themselves while online shopping, which is becoming more popular during the holidays. Adobe is projecting an eleven percent increase in online spending during the holidays this year, amounting to a whopping 83 billion dollars. So that’s 83 billion dollars that will be up for grabs (compared to just 3 billion on Cyber Monday), so it’s naïve to think that criminals are just going to ignore the opportunity. Last year, F-Secure Labs registered a sharp increase in ransomware detections during November and December, including a 300 percent increase in the Browlock police-themed ransomware family. Sullivan published a recent blog post examining the Crytowall ransomware family, which he says is prevalent during the holiday season but virtually disappears in early January – when people celebrating Orthodox Christmas in Russia begin their holidays. One easy way to protect yourself from ransomware and other online threats while holiday shopping is to be conscious of the threat landscape. Its trends like these that Sullivan pays attention to, and warns others to do the same. “It would be safe to say that people should be worried about ransomware this holiday season, and probably through next year. I expect that we, or at least security researchers, will look back on 2016 as the year of extortion.” For example, even though mobile device are now widespread and used by many people, they’re not necessarily good tools to use for making financial transactions while online shopping. “I use an iPad running Freedome for the vast majority of my online browsing, which works great for me because it’s easy to use and I can bring it with me if I leave the house. And between the security benefits of a VPN and the relatively small amount of malware targeting iOS devices, I feel pretty confident in using it to casually window shop on different websites. But I always use a PC to make actual purchases. I trust that my PC is secure and the actual keyboard makes it easier to enter financial data.” You can find more great advice on how to stay safe while online shopping here.

F-Secure Bringing a totally new Future for the Internet to SLUSH 2015

#SLUSH15 is almost here, and F-Secure’s participating in this year’s event in a big way. There’s going to be a big #smartsecurity announcement about the Internet of Things, as well as a couple of presentations from F-Secure personnel. SLUSH, a well-known exposition for startups in the tech industry, has become a huge international event. Both SLUSH and F-Secure call Helsinki home, so it’s only natural for F-Secure to be an active participant at the annual conference. F-Secure made waves last year after the cybersecurity company hacked the venue’s bathrooms to get people talking about online privacy. Several of the company’s researchers and personnel also put in appearances at last year’s SLUSH, including cyber security expert Mikko Hypponen, and F-Secure’s Executive Vice President, Consumer Security, Samu Konttinen. [youtube https://www.youtube.com/watch?v=u93kdtAUn7g&w=560&h=315] [youtube https://www.youtube.com/watch?v=HB-qBhWV65s&w=560&h=315] And they’re both back this year! This year, Samu will be giving a keynote address on SLUSH’s Silver Stage. His talk is called “Your home, your rules – The internet of what ifs”, and runs from 11:45am to 12:00pm (Helsinki time) on November 11th. Samu’s enthusiasm for topics related to security and online privacy will give people valuable insights into how IoT devices are creating new security challenges, and what people can do to protect themselves. Mikko will be appearing on SLUSH’s Black Stage at 9:25am (Helsinki time) on November 12th, where he’ll deliver a talk called “The Online Arms Race”. Mikko recently did an interview about this same topic for V3.co.uk, so you can check that out if you want a quick preview about Mikko’s thoughts on this matter. You can follow all of F-Secure’s SLUSH news by following @FSecure_Sense, @FSecure_IoT, and @FSecure on Twitter.
