Attack! Have You Heard of RansomWare – Wannacrypt?

RansomwareWhat is ransomware? Malicious software that locks a device, such as a computer, tablet or smartphone and then demands a ransom to unlock it.

How can you protect yourself? Anti-virus software can protect your machine, although cybercriminals are constantly working on new ways to override such protection.
Updating the OS will take care of most vulnerabilities. Do not click on questionable links or open suspicious attachments as this can save headaches. This helps limit the spread of ransomware if hackers do get into your system.

How does it work?

  1. The malicious Ransomeware software is normally contained within an attachment to an email that masquerades as something innocent. Once opened it encrypts the hard drive, making it impossible to access or retrieve anything stored on there – such as photographs, documents or music
  2. Ransomware is a kind of cyber attack that involves hackers taking control of a computer system and blocking access to it until a ransom is paid.
  3. It enters a computer when a user mistakingly clicks or downloads a malicious file
  4. It can also spread via a worm, embedding itself within a network, this is instead of relying on humans to spread by clicking
  5.  Experts warn that there is no guaranteed access given after payment

It is interesting to note that Microsoft have already taken measures to save the world from this menace. You can visit Microsoft blog post about this attack – Click here to view.

How to Save Your Data from Windows 10 Automatic Update

This information will be of immense value to you if your computer runs on metered Internet connection – maybe through WiFi, USB modem, etc. I may need to remind you that Microsoft in Windows 10 enforced that Windows Updates must occur automatically whenever they available – ‘whether you like it or not!’ unlike previous editions of Windows where you can stop the updates, or schedule them at appropriate times.

Windows 10 will be great, but it needs more time - Image credit MicrosoftI want to make clearer that automatic updates are typically a good thing and I recommend leaving them on in general. However, majority of users (particularly in Nigeria!) have just a small amount of data connection that they need to do their works on their PCs and these updates eat a lot of data, sometimes in Gigabytes (GB). And the users may not have such amount of data to spare.

Let us now see how you can stop these updates from running automatically, thereby saving you some coins. To proceed, you need to identify the edition of your Operating System – Pro, Home or Enterprise (contact us if you don’t know how to confirm this).

For Pro and Enterprise editions, follow these steps:
Step 1

  • Open the Settings App (Win + I)
  • Open the ‘Network & Internet’ section
  • Open ‘Wi-Fi’ and click ‘Advanced Options’
  • Toggle ‘Set as metered connection’ to ‘On’

Step 2

  • Open the Run command (Win + R), in it type: gpedit.msc and press enter
  • Navigate to: Computer Configuration -> Administrative Templates -> Windows Components -> Windows Update
  • Double click the Configure Automatic Update, then click Enable
  • Change the Configure Automatic Updates setting to ‘2 – Notify for download and Untitlednotify for install’. Click Ok.
  • Open the Settings app (Win + I) and navigate to -> Update and Security -> Windows Updates. Click ‘Check for updates’ which applies the new configuration setting
  • Restart

Step 3: For Windows 10 Home editions
Windows 10 Home Edition does not have the features of the two steps described above. So follow the steps below to stop the automatic update if you must…

  • Fig 2 - Turn off Windows Update in Windows 10Open the Run command (Win + R), in it type: services.msc and press enter
  • From the Services list which appears find the Windows Update service and open it
  • In ‘Startup Type’ (under the ‘General’ tab) change it to ‘Disabled’
  • Restart

Now You Can Be Tracked By Websites you visit via Your Device Battery Status

battery-iconsIn one of the newest development in the IT Industry, Website owners keen on tracking internet users have yet another means of doing so by simply requesting for it from the browser. This is courtesy of a feature the W3C added to HTML5 that lets a website interrogate the state of a visitor’s battery.
According to the research paper by International Association for Cryptologic Research, “all the information exposed by the Battery Status API is available without users’ permission or awareness.” The original rationale behind the spec was that if a server could access a user’s battery state, it could send out a lighter and less resource demanding version of a page for someone with low battery remaining, and heavier versions for people with full battery life. “Although the potential privacy problems … were discussed by Mozilla and Tor Browser developers as early as 2012 [when the API was introduced], neither the API nor the Firefox implementation has undergone a major revision,” the paper states.

Battery properties available to websites include the level, chargingTime, and dischargingTime by calling the navigator.getBattery() method in JavaScript. “When consecutive visits are made within a short interval, the website can link users’ new and old identities by exploiting battery level and charge/discharge times. The website can then reinstantiate users’ cookies and other client side identifiers, a method known as respawning,” the paper claims.
“Note that, although this method of exploiting battery data as a linking identifier would only work for short time intervals, it may be used against power users who can not only clear their cookies but can go to great lengths to clear their evercookies.” The API is only implemented in Firefox, Chrome, and Opera at the moment.

Hackers Attack Antivirus Company’s Server, Steal Sensitive Data

downloadIn an interesting twist, one the most popular and much-respected Antivirus and computer security firms BitDefender has recently been hacked and has had a portion of its customer data leaked.

The data breach on BitDefender is incredibly embarrassing for the security firm, not merely because the company failed to prevent its customers data from hackers, but also because the reputed computer security company did not encrypt its customers’ most sensitive data.

The hacker, who uses the online alias DetoxRansome, managed to break into a Bitdefender server that hosted the cloud-based management dashboards for its small and medium-sized business clients, and extracted usernames and passwords belonging to these clients. This is because these details were saved in a plain unencrypted form.

The Romanian security company admitted its system was breached and said that the attack on its system didn’t penetrate the server, but a security hole “potentially enabled exposure of a few user accounts and passwords.”

After demanding a $15,000 ransom which the firm refused to pay, the hackers uploaded a list of over 250 usernames and passwords over the internet.

“The issue was immediately resolved, and additional security measures have been put in place to prevent its reoccurrence. Our investigation revealed no other server or services were impacted,” said that company’s spokesperson.

BitDefender is currently working with law enforcement to investigate the issue.

Etisalat USB Modem Software
