Symantec has quietly rejigged its Norton software line-up, eliminating some old favorites and bringing in some fresh new blood in a bid to provide a more rounded offering to an audience facing security and privacy challenges from multiple fronts.
Highlighting the fact that security is no longer restricted toantivirus, the change also marks the first real step towards integratingLifeLock, theidentity theft protectionservice Symantec acquired in 2017 for $2.3 billion, into the security suite.

Ransomware has long been a menace for organizations and consumers. Global damage cost estimates reach about 10 billion USD per year. After all these years, why does ransomware continue to be so good at being so bad? The answer is a combination of the security industry’s history of largely ineffective responses to ransomware and how ransomware developers use psychology to trick users into thinking they’re responding to requests from a colleague or even donating Bitcoins to a children’s charity.
Ransomware is hardly new and unknown since it has been around since 1989. Yet it remains one of the most common and successful attack types. According to reports, there were over 180 million ransomware attacks in the first six months of 2018 alone. The adoption of cryptocurrencies and Tor have served to amplify the prevalence of ransomware dramatically.

How to test anti-ransomware: This is how we do it
More than half of working adults don’t know what ransomware is
Every 14 seconds, an organization somewhere in the world falls prey to a ransomware attack. But the bad actors are not narrow in their focus and typically target many organizations and users at once. For example, think back to the global WannaCry attack that resulted in losses of almost $4 billion.
How ransomware works
The details of how one attack gets inside a system or an organization, i.e., its “attack vector” are irrelevant. It can be phishing, exposed RDP or any other avenue that ransomware developers leverage to get in.
Instead, let’s take a look at what happens when ransomware actually interacts with your file system and encrypts data. First, ransomware process(es) locates the files it wants to encrypt. These are most often based on file extensions and target your most valuable assets such as Microsoft Office documents or photos, while leaving operating system files intact to ensure that system will still boot. Then the malware encrypts that data in memory and destroys the original file.
One route ransomware takes is to save encrypted data into a new file and then delete the original.
Another option, and probably the most devious one, is to write that encrypted data into the original file itself. In this case, the original file name is left intact, complicating the recovery by making it difficult to distinguish between encrypted files and those that haven’t been encrypted.
A third method is for ransomware to create a new file like in the first option, but then instead of the delete operation use rename to replace the original file.
After completing the encryption process, the infamous ransomware note is displayed. We know that part of the story quite well from the news coverage.

In 2017, the value per Bitcoin reached over €20,000 (£17,324) – a climax in the hype surrounding the cryptocurrency. However, confidence has been lacking for the price to remain stable. To date, online currencies are more speculation than real means of payment as concerns around security are being raised. An establishment is only possible if users believe in the value’s sustainability, and this applies to every means of payment.
In no industry is the subjective perception of security as important as in the field of finance. Both private users and large customers are increasingly handling transactions online, so the fear of digital innovation isn’t what stop them from adopting this type of currency. It’s security they really care about, or rather their data’s security. The financial sector has acknowledged this and, must above all focus on security to appease the apprehensions some might have.
Blockchain is considered safe to this day, yet speculation is causing such great uncertainty that cryptocurrencies have not yet developed into serious competition for established currencies. IT decision-makers should therefore always keep in mind the importance of the users’ sense of security in their industry. As part of their digital transformation, many financial organisations have implemented several security tools and also have their own security teams.
Keeping ahead of the curve: understanding threat intelligence
Permission to intrude: hiring hackers to bolster cyber defences
These are necessary to comply with legal requirements. After all, almost all other sectors depend on the financial sector. Of course, it is also about the security of customers and partners’ data. Therefore, it is not surprising that this industry has taken a pioneering role over the years. While some organisations already have their own Security Operations Centres (SOCs) to respond to potential threats and identify Indicators of Compromise (IoCs), they should think about other ways to optimise their organisa

Windows 10 has been struck by a worrying problem in that some of its core (installed by default) apps are displaying fraudulent adverts which could potentially play all sorts of nasty tricks on the user.
As spotted by Ghacks and first highlighted on Microsoft’s German support site, a post has since appeared on the US Answers.com website clarifying the issue that affects apps including Microsoft News and Weather, and possibly other applications or indeed Microsoft services (MSN Money is also mentioned).

These malicious banner adverts are being erroneously picked up by Microsoft’s ad servers and presented to the user. They contain some kind of bait to get the user to click them, either claiming that your PC is infected with viruses, or suggesting that you have won a lottery.
If clicked, they will take you to some malicious site which will seemingly try to sell you a ‘cure’ for the (non-existent) virus, drop malware on your machine (or

Of all the malware attacks you can experience, ransomware has to be one of the worst. While some paid-for anti-virus programs will protect against ransomware, most free ones do not. The result is that most PC’s are likely vulnerable to this particularly nasty form of attack.
Ransomware became big news when WannaCry first appeared in 2017, crippling organizations all around the world, and while attack volume has lessened since then, the threat of attack has now become routine.
There are two main forms of ransomware. The first encrypts your files so you can’t access them, unless you pay a ransom, usually to an anonymous bitcoin account, to the attacker. The other form locks up your PC so that your only apparent option is to pay to gain access to your PC again.
This is why it’s all the more important to ensure that you have some form of protection on your PC against ransomware attacks. And while we list five of the best white knights who aim to help recover your PC from ransomware, it remains a stressful process you’re best avoiding by having protection in the first place.

If you haven’t yet fallen victim to a ransomware attack and want to protect your PC proactively, consider a dedicated prevention tool like ZoneAlarm Anti-Ransomware, which uses behavioral analysis to identify processes that act like ransomware – even if it’s not yet a specific known threat – and automatically backs up your files if it detects anything. It carries a subscription fee, so we haven’t included it in our main roundup, but $1.99 per month for one PC is a modest fee compared to the ransoms charged by criminals.

1. Avast Free Ransomware Decryption Tools
Solutions designed to defeat different strains of ransomware
Tackles 21 forms of ransomware
Not all ransomware encrypts data in the same way, so security software providers have to create specific solutions as new threats emerge. At the time of writing, the security experts at Avast have developed Free Ransomware Decryption Tools to tackle 21 different strains of file-locking ransomware.
To help you work out which one you need, Avast has provided a detailed description of how each form of ransomware works, what extension you’ll see on the encrypted files, and an example of the type of message the virus creators have prepared for their victims.
Once you’ve downloaded the appropriate tool, it will guide you through the process of wiping out the ransomware without paying the criminals. You’ll need to provide two versions of the same file – an encrypted one, and the original.
This will be easiest if you made a backup before the infection, but Avast also suggests locations where you might be able to find unaffected original files. The tool will then compare the two and use the results to determine the password.
A single download that can defeat 27 breeds of ransomware
All tools provided in one download
Decryption may be incomplete
Trend Micro Ransomware File Decryptor is updated regularly with new ransomware definitions, and at the time of writing it can release files locked by 27 different types of ransomware and their variants.
Unlike Avast, Trend Micro bundles all its decryption tools into one bundle, but you still need to tell it what form of ransomware it’s
