According to Checkpoint Research, ransomware attacks have surged significantly, hitting a double-digit increase of 93 percent year-on-year. As of June 2021, the number of organizations impacted by ransomware has risen to 1,210. This exponential rise is also attributable to the migration to remote work globally. The amount paid by victims of these attacks has increased by almost 300 percent in 2020 alone

These staggering statistics paint a grim picture of the security threat that companies face. As early as July 2021, as many as 1,500 businesses world-wide have been affected by ransomware attack -- REvil. The group has reportedly used Kaseya IT software as backbone for this notorious attack. Around $70 million dollars were demanded from the affected companies to restore business data. The companies that majorly came under the radar were supermarkets, IT companies -- primarily small to medium sized, schools and kindergartens

Ransomware is a major problem and ideally while you'd like to avoid being attacked, the chances are that at some point you're going to be a target.

So, what happens following an attack and what should organizations be doing immediately afterwards to lessen the impact? We spoke to Ed Williams, EMEA director of SpiderLabs at Trustwave, to find out and to get some tips on how to proactively secure against ransomware attacks in future.

It is now almost three weeks since the gigantic ransomware attack that exploited a vulnerability in Kaseya VSA remote management software. The attack affected millions of devices and the group behind it, REvil, had been demanding a $70 million ransom.

There had been great concern about the fall out from the attack due to the apparent disappearance of REvil which made it impossible for anyone willing to pay the ransom to do so. Now a universal decryption key has been obtained from a "trusted third party", giving victims the chance to regain access to their data without the need to part with any money.

According to a new survey of 200 decision makers in businesses that had suffered a ransomware attack since 2019, more than half of victims had received anti-phishing training and 49 percent had perimeter defenses in place at the time of attack.

The study conducted by Sapio Research for Cloudian finds that phishing continues to be one of the easiest paths for ransomware, with 24 percent of attacks starting this way. Phishing succeeds despite the fact that 54 percent of all respondents and 65 percent of those that reported it as the entry point have conducted anti-phishing training for employees.

Ransomware, and indeed malware generally, used to be something of a cottage industry, the preserve of individuals or small groups. But new research from threat intelligence company KELA shows that it's becoming a highly professionalized industry.

Many cybercriminals are now specializing in different areas, so that the coding, spreading, extracting and monetizing processes might all be carried out by different people.

Ransomware attacks are a type of cybercrime where hackers will use malware to encrypt computer (or network) files, locking users out of the system until a ransom is paid to a cybercriminal. Ransomware attacks have been around since the mid-2000s but they’ve made recent headlines as attacks against Colonial pipeline and the U.S. meat industry have shown that they are more than just a technology challenge, and can also significantly disrupt everyday life.

Between ransoms paid and lost productivity, ransomware attacks cost U.S. businesses an estimated $2.3 Billion in 2020 alone. The disruption caused by the COVID-19 pandemic, the popularization of cryptocurrency as a ransom payment, and support (or lack of prosecution) from foreign states have created an ideal environment for ransomware attacks to flourish.
