18 Oct 2017 - Windows 10 Fall Creators Update contains Ransomware protection

The Windows 10 Fall Creators Update includes an amazing new feature: Folder protection against ransomware. Here's how to activate this essential security feature.

Ransomware is everywhere nowadays, and it's been nearly impossible to stop it. Microsoft thinks it may have the answer, and has therefore added a new feature to Windows Defender in the Windows 10 Fall Creators Update that is designed to stop the growing form of malware from snagging more victims.

The feature called Controlled Folder Access prevents programs from making any change to files or folders that are set as protected. By default that includes Windows system folders, Documents, Pictures, Videos, Music, Favourites, and Desktop folders for each user.

Exclusions for certain apps can be made, folders can be added, and Controlled Folder Access can be toggled on and off by taking the following steps.

  1. Open Windows Defender Security Center.
  2. Click on the Virus & Threat Protection menu item.
  3. Under that option click on Virus & Threat Protection Settings.
  4. Scroll down to the fourth item in the list that pops up: Controlled Folder Access. Toggle the button to On.
  5. Say yes to the popup window.
  6. Once it's on, the options to select folders and allow app exclusions will appear below the toggle button. Click on them if you want to make changes.

12 Oct 2017 - Kaspersky software 'used by Russian state hackers to trawl for US secrets'

Popular anti-virus software used by hundreds of thousands of people and businesses in Britain was reportedly hijacked by Russian government hackers to trawl for American secrets.

Cyber spies allegedly used software from the Russian firm Kaspersky Lab which is installed on computers around the world to improvise a search tool and look for the codenames of secret US programs.

Discovery of the operation led the American government to last month order the removal of the software from its computers, the New York Times reported.

04 Oct 2017 - Yahoo says all three billion accounts hacked in 2013 data theft

In a shocking legal disclosure on Tuesday, Yahoo admitted that all 3 billion of its accounts were hacked in a 2013 data theft, tripling its earlier estimate of the size of the largest breach in history.

Yahoo said last December that data from more than 1 billion accounts was compromised in 2013, the largest of a series of thefts that forced Yahoo to cut the price of its assets in a sale to Verizon.

Yahoo on Tuesday said “recently obtained new intelligence” showed all user accounts had been affected. The company said the investigation indicated that the stolen information did not include passwords in clear text, payment card data, or bank account information.

But the information was protected with outdated, easy-to-crack encryption, according to academic experts. It also included security questions and backup email addresses, which could make it easier to break into other accounts held by the users.

19 Aug 2017 - Hacker breaks Apple encryption, exposes iOS mobile security

A hacker going by the handle xerub has just released what he claims to be a full decryption key for Apple's Secure Enclave Processor (SEP) firmware.

This could be a major blow for iOS security because of the importance of the SEP: It handles Touch ID transactions and is completely isolated from the rest of its host device. Your iPhone, iPad, or iPod has no idea what's going on in the SEP, and that means no one else does either"at least until today.

Now that its firmware code is exposed it's open season on SEP vulnerabilities.

  • NEVER open email attachments unless you both expect them AND you know and trust the source
  • Educate your staff about the dangers of e-mail attachments
  • Ensure your backups are running and that they are current
  • On company networks, only give users access to areas they need. Lock down the rest.

A widespread Samba vulnerability has raised the possibility of attacks similar to WannaCry hitting Linux and Unix systems.

Researchers warn that many Linux and Unix systems contain a Samba vulnerability that could eventually lead to attacks similar to WannaCry or worse, if IT pros don't remediate quickly.

According to the Samba security advisory, the vulnerability (CVE-2017-7494) affects versions 3.5 (released March 1, 2010) and newer. The Samba vulnerability is remotely exploitable and could allow "a malicious client to upload a shared library to a writable share, and then cause the server to load and execute it."

15 May 2017 - Bitdefender response : Bitdefender Prevents WannaCry Ransomware Attacks

Bitdefender’s next gen machine learning provides zero day protection from WannaCry ransomware attacks

#DontNeedtoCry - On May 12th, the WannaCryptor (WannaCry) ransomware family infected thousands of computers across the world. In just 24 hours, the number of infections has spiked to 185,000 machines in more than 100 countries.

The attack is particularly dangerous for businesses because it takes just one employee to become infected for the attack to spread in the entire network, and sometimes even across countries to other subsidiaries, without any user interaction. This happens because the ransomware has a worm component that leverages a recently discovered vulnerability, affecting a wide range of Windows operating systems, including 2008, 2008 R2, 7, 7 SP1.

The attacks have caused major disruption to hospitals, telecom companies or gas and utilities plants. Among the organizations that took the worst hits is the National Health Service (NHS) in the UK.

Why is this attack particularly dangerous among traditional ransomware attacks?

WannaCry automated the exploitation of a vulnerability which is present in most versions of Windows allowing a remote attacker to run code on the vulnerable computer and use that code to plant ransomware without any human and local action. This never before seen behaviour makes it the perfect tool to attack specific environments or infrastructures, such as servers running a vulnerable version of the Server Message Block (SMB protocol).

Customers running Bitdefender are not affected by this attack wave.

Our next-generation machine-learning and memory introspection technologies ensure that our customers have always been safe from WannaCry, the world’s most aggressive piece of ransomware, AND will be similarly protected from the next such attack.

Endpoints running Bitdefender GravityZone are protected from hour zero against this attack wave and they are not affected by this new family of ransomware as our products detect and intercept both the delivery mechanism and all variations of the WannaCry ransomware known to date. Bitdefender Machine Learning models, available in all editions of Bitdefender GravityZone, are designed specifically to catch never before seen attacks at pre-execution stage.

Moreover, Bitdefender’s newly introduced Hypervisor Introspection solution was able to prevent exploits of the EternalBlue vulnerability from hour zero as well, before it was patched by Microsoft. The solution is capable of detecting memory violations in the raw memory stack, without knowing the vulnerability beforehand, and can therefore effectively prevent the attack.

We encourage you to stay tuned and test our new technologies and innovations like Hypervisor Introspection. We are constantly innovating to keep our customers safe!

Thank you for trusting and promoting Bitdefender solutions!

14 May 2017 - NHS ransomware hack and the failure of the public sector

On Friday a significant portion of the NHS was hit by a ransomware attack that crippled systems and encrypted data. It looks like patient data remains safe, presumably due to backups, but they estimate it will be a number of days until the systems are fully restored.

The details of this attack are interesting. The Windows flaw this attack exploits was fixed by Microsoft on March 14th this year. All updated machines were therefore immune to this attack.

The reason sections of the NHS were hit so badly is that they, unbelievably, were still using Windows XP to run critical systems. Windows XP is now 15 years old and all support ended in 2014. There have been no XP fixes issued for 3 years!

It is quite frankly a shocking lack of competence for the NHS to be in this position, one would hope that heads would roll for this but as it is the public sector I don’t have much faith in that.

This cloud, however, may have a silver lining. For years the private sector has dealt with these attacks with little or no help from the government/police/security services. Perhaps now they will start to take some action?
