Here is a list of all the domains caught so far sending your data back to Microsoft in Windows 10:

Attackers can access Dropbox, Google Drive, OneDrive files without a user’s password

August 6, 2015 – 7:19 PM

Hackers don’t even need your password anymore to get access to your cloud data.

Newly published research, released at the Black Hat conference in Las Vegas on Wednesday by security firm Imperva, shows how a “man-in-the-cloud” attack can grab cloud-based files — as well as infecting users with malware — without users even noticing.

The attack differs from traditional man-in-the-middle attacks, which rely on tapping data in transit between two servers or users, because it exploits a vulnerability in the design of many file synchronization offerings, including Google, Box, Microsoft, and Dropbox services.

This is not just an issue for consumers, but also businesses, which increasingly use cloud-based services to share sensitive customer and corporate data.

The report by Imperva, which has a research unit as well as having a commercial stake in the security space, said in some cases “recovery of the account from this type of compromise is not always feasible.”

The attack works by grabbing the password token, a small file that sits on a user’s devices for convenience (which saves the user from entering their password each time). When the token is obtained, either through a phishing attack or a drive-by exploit, it can be used to fool a new machine into thinking the attacker is the account’s owner. From there, the attacker can access and steal files, and even add malware or ransomware (which is on the rise) to the victim’s cloud folder, which can be used for further attacks.


Windows 10 Upgrade Spam Carries CTB-Locker Ransomware

August 3, 2015 – 8:12 PM

In the week since a free upgrade to Windows 10 was made available, users have learned a of about a host of built-in privacy and security issues, the most troubling being a native feature called Wi-Fi Sense that grants access to your Wi-Fi network to contacts stored in a host of online services.

Now hackers are in on the game. The inevitable Windows 10 spam and phishing emails have surfaced, including a serious threat via a spam campaign spoofing Microsoft and ultimately dropping ransomware on users’ machines.

Researchers at Cisco TALOS said on Friday they spotted spam carrying an archived attachment from an email address in Thailand spoofing update at Microsoft[.]com. Users who download and execute the files inside the zip archive are hit by the CTB-Locker brand of ransomware. CTB-Locker behaves like most strains of crypto-ransomware; it’s spread via email, exploit kits or drive-by downloads, encrypts documents stored on the computers and demands a ransom paid in Bitcoin in exchange for the encryption key. This campaign gives users a 96-hour window to deliver payment, which is shorter than other campaigns making use of CTB-Locker.

CTB—also known as Critroni—stands for Curve-Tor-Bitcoin, and uses elliptic curve cryptography to encrypt files, and uses the Tor anonymity network for command and control operations.

The current Windows 10 spam campaign has a chance to be quite lucrative, given the thirst most consumers have for the latest and greatest technology. Users, however, must first reserve their spot in a queue in order to get the free upgrade to Windows 10. The spam emails may trick victims into thinking this is their notification from Microsoft to upgrade; legitimate upgrades are done via download, not email, Microsoft said.


Flash/HTML5 in Firefox

July 31, 2015 – 9:01 PM

I’ve been asked a lot lately about uninstalling Flash in Firefox and why users are still being served the Flash versions on Youtube, for example, and requiring them to install it before displaying the video.  I was asked again today and thought I would quickly post something about it.

The easiest way is to install the User Agent Switcher add-on and pick a user-agent string that is not compatible with Flash (iPad or iPhone strings work well).  This will force the HTML5 version of the pages/videos.
