Is Ransomware a Threat to Enterprise Back-ups?

Recently, in May 2017 a ransomware named WannaCry was the matter of discussion among many organizations. The considerable damage WannaCry made to some of the corporate giants was constantly in the news and organizations were horrified due to the extensive loss in data. However, interestingly it didn’t take much time for the organizations to recover the lost data back from back-ups. Although this is a good thing, it may be an alarming situation if the enterprises are slowly adapting to ransomware, it is surely going to target advanced backup strategies.

How could ransomware target system backups?

When the user attempts to hold data located at the target for ransom, it can be difficult for the target to restore it from the backup. Most of the home users and municipal corporations don’t invest heavily on data backup and recovery systems and rely on the basic, built-in protection for their computers, laptops, and servers. This basic system, known as Windows Volume Shadow Copy is present in the editions since Server 2003 and XP and stores pictures of the files on an endpoint. As it is commonly used by home users as well as small businesses, the ransomware such as WannaCry have tools to delete it.

Ransomware like Locky, WannaCry, Cryptolocker, and CryptXXX are capable of deleting the volume shadow copies with the help of strings in command line. This is probably the reason why some ransomware variants failed to make much profit as most enterprises use more robust protections than just shadow copies. WannaCry hit enterprises rather than attacking small businesses or home users and as a result global companies with thousands of employees fell victim to its attack. Within an enterprise, data backup adoption is at extremely high levels while cloud backup and recovery comprise a high percentage of cloud-based investments. Companies have the best potential to overcome a ransomware attack by restoring from backup.

Conclusively, with a malware like WannaCry, it’s proven by the ransomware authors they can attack enterprises. However, they don’t have a persistent mechanism. Additionally, the enterprise backups are too robust to cause much damage as they are capable of retrieving data from backups within a day at most. Although the enterprise backup systems are sufficiently secured, there’s something really to worry about as hackers intelligently innovate ways to overcome these technical obstacles. So, companies must be prepared with the possibility of ransomware attacking their backups for encryption or deletion.

Beware of PC Registry Cleaners: Are They Safe?

Windows registry is a repository which collects massive data about your computer as it practically records everything that is performed on Windows. It is literally a cluttered space as Windows, by itself is not capable of cleaning the system efficiently as it’s always busy in creating new entries. Even though you uninstall a program or application, it leaves some unneeded pointers in the registry and thus slows down your system.

To resolve this issue, many PC registry cleaners are marketed to the users with the claim that they would speed up the computer system making it function better. However, before making your decision to purchase or install a free PC cleaner on your computer system because above all claims they make everything depends on the condition of your registry and the effectiveness of the registry cleaner that you select. Another thing to be considered is that registry cleaners usually delete things from the registry. While most of the times it is safe, there are times when registry cleaners caused serious problems to the computers and their data. Though most of the modern PC registry cleaners feature built-in methods to reverse changes when things go against expectations, it is not recommended to invest in an advertised PC cleaning system. Being diligent while making your choice is the first step towards protecting your system from unwanted attacks. Also, remember to back up your registry before letting the cleaner to remove or delete entries. Doing this would save you even if the registry cleaner doesn’t have an ‘undo’ option, you can use the backed up registry file to restore it back.

One more important thing to be highlighted is that registry cleaners do not speed up the computers and so, you do not need to run them regularly. Hackers are talented enough to compromise the quality of the wide range of PC cleaning software as happened with CCleaner software in August and September wherein malicious hackers had illegally modified the version 5.33 of CCleaner software which was available for download for about a month.

Your computer data is precious and we, at Net Activity, Inc. recommend you not to install any PC registry cleaners without proper survey of their history. Also, think twice before going for cleaners that invest huge amounts on marketing and advertisements as they are no good.
