Study reveals corporate crypto-ransomware attacks have increased six-fold

New research has found that the number of crypto-ransomware attacks against the corporate sector has grown six-fold, surging from 27,000 between 2014 and 2015 to 158,000 between 2015 and 2016.

The figures were brought to light by new data from the Kaspersky Security Network report. It shows that ransomware attempted to encrypt the critical data of every tenth corporate user.

As the overall number of encrypted ransomware attacks have risen, cyber-criminal ransomware attacks targeting businesses have become more frequent, particularly among small and medium-sized companies. A separate report, the IT Security Risks 2016 study from Kaspersky Lab and B2B International, confirms this trend with 42% of respondents from small and medium-sized businesses agreeing that crypto-malware was one of the most serious threats they faced last year.Study reveals corporate crypto-ransomware attacks have increased six-fold TechNative

For small companies, any data unavailable – regardless of the length of time – can lead to significant losses, or bring their entire operations to a halt. If an organization has not been following proper IT security measures to ensure the safety of its critical information, purchasing the decryption key from cyber-criminals is the only way to recover their files. However, this does not guarantee complete data recovery and the best way for businesses to protect their sensitive data from a cyberattack is to prevent the attack in the first place.

When it comes to crypto-malware, there is wide attack vector including web, mail, software exploits, USB devices, and others.” said Konstantin Voronkov, Head of Endpoint Product Management Kaspersky Lab. “Since there are many different ways to attack, to avoid a security incident, organizations should have an anti-malware solution in place and should be educating employees on where attacks come from. Most importantly, they need to know not to open suspicious email attachments, visit untrusted web resources, or plug USB devices into unprotected computers.”

Kaspersky Lab experts recommend that small and medium-sized companies should follow several simple safety rules:

● Make regular backup copies of all important files. Companies should have two backups: one in the cloud (for example Dropbox, Google Drive, etc.), and another on an additional      server or on removable media if the data volume is not too big.

● Trust well-known and respectful service providers who invest in security. Usually you can find security recommendations on their websites, they publish third party security audits on cloud infrastructure. Don’t assume cloud providers can’t have security, availability or data leakage problems. Raise the question – what do you do if your security provider losses your data? There should be transparent data backup and restore processes together with data protection and access control.

 Avoid using only free security and anti-malware software: small businesses expect the basic security tools offered within free solutions to be sufficient. Free tools do provide basic protection, but they fail to provide multi-layered security support. Instead, take a look at dedicated solutions that do not require a large financial outlay, but deliver a higher level of protection.

 Regularly update your OS, browser, antivirus, and other applications. Criminals use vulnerabilities in most popular software to infect user’s devices.

 Prevent IT emergencies – invite an expert to configure security solution for your company. Small businesses usually don’t have an IT department or full-time dedicated administrator, they simply rely on the most tech-savvy person in the office to take care of the computers, in addition to their regular duties. Don’t wait until something breaks – use IT support from an IT service provider to review your software and security configuration in advance.

If you have had your corporate files ciphered, it is worth checking whether it is possible to recover them by using free utilities or decryptor keys from Kaspersky Lab.
