Tighter login procedures make Twitter a safer place

Since Twitter first became popular enough to attract crooks and scammers, phishing has been a consistent problem.

Generally, Twitter phishing looks like this: First, you get a direct message linking you to some site for some reason. Next, you login into this third-party site using your Twitter credentials. Finally, everyone in your Twitter stream gets sent the same message you got spreading the scam into infinity.

These scams were enabled by the fact that Twitter users have grown comfortable logging into other sites and tools using their Twitter credentials. This is because, in an effort to make its service more useful, Twitter has had a very open policy for third-party developers.

Thankfully, most of these scams have not result into much direct harm for users. Sean in the F-Secure Labs suggested that the main purpose of phishing was to create trending topics/trending terms to improve SEO attacks.

Back in April, I suggested a draconian way of avoiding Twitter phishing: never click on any links. Thankfully, that became less necessary as Twitter’s increasingly effective filtering of shortened links has helped to minimize these attacks.

And here comes a real change for the better.  As of August 16, 2010, you will not be able to use your login and password to login into Twitter using any site but Twitter.com. Any third-party site that you want to use has to connect to your Twitter account directly using the OAuth procedure.

This means Twitter can say to the world, don’t log into Twitter unless you’re on Twitter. And if users listen, Twitter phishing will be history. Just a little change, but a step in the right direction.

@FSecure regularly tweets about Twitter safety using the hashtag #twittersafety. You can also read our How to Tweet Safely: 6 Tips for Safer Tweeting.

GameOver ZeuS: The Kind of Game You Don’t Want On Your Computer

Unlike Team Fortress 2 or Doom, two of the most popular PC games of all time, GameOver ZeuS is not a game you can buy online or would willingly download on to your computer. What is GameOver ZeuS? While we’ve talked about banking Trojans before, none have been as detrimental to users as the GameOver ZeuS or GOZ Trojan, which initially began infecting users in 2012. Gameover ZeuS is designed to capture banking credentials from infected computers, and make wire transfers to criminal accounts overseas. It was allegedly authored by Russian hacker Evgeniy Bogachev, who then implanted it on computers all around the world; building a network of infected machines - or bots - that his crime syndicate could control from anywhere. It’s predominately spread through spam e-mail or phishing messages. So far, it’s been estimated to scam people out of hundreds of millions of dollars and it’s only getting worse. It doesn’t stop there; Gameover ZeuS can also be modified by hackers to load different kinds of Trojans on to it. One such Trojan is a ransomware called CryptoLocker, which is a devastating malware that locks a user’s most precious files by encrypting all the files until he or she pays the hacker a ransom. In June 2014, the FBI, Europol, and the UK’s National Crime Agency announced they had been working closely with various security firms and academic researchers around the world and took action under a program dubbed “Operation Trovar.” This initiative temporarily disrupted the system that was spreading the Trojan and infecting computers, allowing a temporary pause in additional computers from being infected. However, computers that were already infected remained at risk, as they were still compromised. What’s next? The disruption of the GameOver ZeuS botnet was a great success in many ways, but it’s not over. Our security advisor, Sean Sullivan, worries that this temporary disruption was actually more dangerous than completely taking it down. “Without arresting Bogachev, Gameover ZeuS is still a huge threat and likely to evolve to become more dangerous. The hackers can just as easily program a future version of the Trojan to initiate a “self-destruct” order (like destroy every file on a computer) if the ransom isn’t paid, or if authorities try to intervene.” What can we do to protect our digital freedom? Beware of malicious spam and phishing attempts — don’t open any attachments within emails unless you are specifically expecting something. Check email attachments carefully, and make sure you don’t open any files that automatically launch, which frequently end in .exe Have an Internet security solution in place and keep it up to date Keep your Windows operating system and your Internet browser plugins updated Back up all of your personal files regularly Also, check your machines to be sure you do not carry the Gameover ZeuS Trojan. For more information on how this powerful Trojan works and how it is spread, check out this this video.

16 ways SAFE protects your devices, your family and you

In the early twenty-first century, when hackers were mostly pranksters, having security software on your PC was mostly about saving you some trouble. In 2014, international crime syndicates regularly co-opt millions of computers in order to systematically steal banking information, take identities and hold files for ransom, security isn't about convenience. It's about giving our families the freedom to live our lives online with out the threat of strangers invading our lives, hijacking our time and money. An anti-virus on one PC is a good step. But who just uses one PC now? Many of us three different devices before breakfast. That's why we created F-Secure SAFE -- it's built to protect all the devices and all of the people in your family.

Why your Apple Watch will probably never be infected by malware

On Tuesday Apple announced its latest iPhone models and a new piece of wearable technology some have been anxiously waiting for -- Apple Watch. TechRadar describes the latest innovation from Cupertino as "An iOS 8-friendly watch that plays nice with your iPhone." And if it works like your iPhone, you can expect that it will free of all mobile malware threats, unless you decide to "jailbreak" it. The latest F-Secure Labs Threat Report clears up one big misconception about iOS malware: It does exist, barely. In the first half of 2014, 295 new families and variants or mobile malware were discovered – 294 on Android and one on iOS.  iPhone users can face phishing scams and Wi-Fi hijacking, which is why we created our Freedome VPN, but the threat of getting a bad app on your iOS device is almost non-existent. "Unlike Android, malware on iOS have so far only been effective against jailbroken devices, making the jailbreak tools created by various hacker outfits (and which usually work by exploiting undocumented bugs in the platform) of interest to security researchers," the report explains. The iOS threat that was found earlier this year, Unflod Baby Panda, was designed to listen to outgoing SSL connections in order to steal the device’s Apple ID and password details. Apple ID and passwords have been in the news recently as they may have played a role in a series of hacks of celebrity iCloud accounts that led to the posting of dozens of private photos. Our Mikko Hypponen explained in our latest Threat Report Webinar that many users have been using these accounts for years, mostly to purchase items in the iTunes store, without realizing how much data they were actually protecting. But Unflod Baby Panda is very unlikely to have played any role in the celebrity hacks, as "jailbreaking" a device is still very rare. Few users know about the hack that gives up the protection of the "closed garden" approach of the iOS app store, which has been incredibly successful in keeping malware off the platform, especially compared to the more open Android landscape. The official Play store has seen some infiltration by bad apps, adware and spamware -- as has the iOS app store to a far lesser degree -- but the majority of Android threats come from third-party marketplaces, which is why F-Secure Labs recommends you avoid them. The vast majority of iPhone owners have never had to worry about malware -- and if the Apple Watch employs the some tight restrictions on apps, the device will likely be free of security concerns. However, having a watch with the power of a smartphone attached to your body nearly twenty-four hours a day promises to introduce privacy questions few have ever considered.
