Ransomware and email attacks are hitting businesses more than ever before

Web Hosting & Remote IT Support

Ransomware and business email compromise (BEC) attacks are hitting businesses more than ever before, a new report by Cisco Talos Incident Response (Talos IR) has claimed.

The report states ransomware and BEC accounted for almost two-thirds (60%) of engagements, combined. There had been fewer BEC engagements this quarter, compared to the previous one, Talos added, noting it was “still a major threat for the second quarter in a row.”

At the same time, Ransomware accounted for almost a third (30%) of engagements this quarter, up by a quarter (22%) compared to the same time three months ago. 

Tech firms in the crosshairs

Furthermore, the researchers observed Mallox and Underground Team ransomware families for the first time, suggesting the number of threat actors in the industry continues to grow. At the same time, Black Basta and BlackSuit ransomware operations continue to wreak havoc among organizations.

The majority of organizations falling victim to either ransomware or BEC attacks are in the technology industry, the report further states. This is due to these firms having extensive digital assets, supporting critical infrastructure. As a result, they have minimal tolerance for downtime and would be more keen to pay the ransom demand and get back to work as soon as possible. Furthermore, tech firms are often seen as gateways into other industries, as well. 

In total, a quarter (24%) of engagements in these past three months were from tech firms, closely followed by healthcare, pharma, and retail. Attacks against tech firms are up by 30%, quarter-on-quarter. 

Talos says that a huge majority (80%) of victims fell prey to ransomware attacks because they didn’t have proper MFA implementations on critical systems, including virtual private networks (VPN). The remainder of the victims fell prey due to either vulnerable, or misconfigured systems, the researchers concluded. Talos IR observed a 46% increase in each of these security weaknesses from the previous quarter.

Mova V70 Ultra Complete review: a full-featured robovac let down by subpar performance

Web Hosting & Remote IT Support Mova V70 Ultra Complete: Two-minute review If you've never heard of Mova as a brand, you're not alone as it was initially only available in select European and South-East Asian countries. The brand, which is owned by Dreame Technology, is now expanding and is supposed to be value-focused side of the company — although you'd be hard pressed to believe that when its latest flagship robot vacuum costs upwards $1,000 / £1,000 / AU$3,000. However, the Mova V70 Ultra Complete brings everything you expect from such an expensive robovac, including some industry-first features that are now being adopted by other brands. This includes suction that's a whopping 42,000Pa at its maximum, as well as the impressively long reach of the side brush and mopping arm (12cm and 17cm respectively). I even love the fact that it eliminates the need for dust bags by us...
