Many Workers Ignore Security Risks To Maximize Productivity

A large proportion of employees often take shortcuts to optimize productivity at work, despite understanding the security risks, new data suggests. According to a survey which polled 8,000 workers worldwide, almost four in five (79%) have engaged in one or more “risky activity” in the past twelve months. In a third of cases (35%), this involved saving passwords to their browser. A similar percentage admitted to using a single password across multiple online accounts, while 23% connected personal devices to corporate networks.

Financial Services Accounting For Nearly 40% Of All Phishing URLs

A report was released for H1 2021, which revealed that there has been a major jump in phishing attacks since the start of the year with a 281 percent spike in May and another 284 percent increase in June, for a total of 4.2 billion phishing emails detected for June alone. For this 6-month window researchers identified Crédit Agricole as the most impersonated brand, with 17,555 unique phishing URLs, followed by Facebook, with 17,338, and Microsoft, with 12,777.

Half Of Organisations Are Ineffective At Countering Phishing And Ransomware Threats

Half of organisations are not effective at countering phishing and ransomware threats. The findings come from a study compiled from interviews with 130 cyber security professionals in mid-sized and large organisations. “Phishing and ransomware were already critical enterprise security risks even before the pandemic hit and, as this report shows, the advent of mass remote working has increased the pressure of these threats,”. “Organisations need multi-layered defences in place to mitigate these risks.”

36% Of Organisations Suffered A Serious Cloud Security Data Leak Or A Breach In The Past Year

As cloud adoption accelerates and the scale of cloud environments grows, engineering and security teams say that risks—and the costs of addressing them—are increasing. The findings are part of the State of Cloud Security 2021 survey. The survey of 300 cloud pros (including cloud engineers; security engineers; DevOps; architects) found that 36% of organisations suffered a serious cloud security data leak or a breach in the past 12 months, and eight out of ten are worried that they’re vulnerable to a major data breach related to cloud misconfiguration. 64% say the problem will get worse or remain unchanged over the next year.

HP Finds 75% Of Threats Were Delivered By Email In First Six Months Of 2021

According to the latest HP Report, email is still the most popular way for malware and other threats to be delivered, with more than 75% of threats being sent through email messages.  The report -- covering the first half of 2021 -- is compiled based on customers who opt to share their threat alerts with the company. HP's researchers found that there has been a 65% rise in the use of hacking tools downloaded from underground forums and filesharing websites from H2 2020 to H1 2021. Some of the tools can solve CAPTCHA challenges using computer vision techniques.

Data Breach Costs Hit Record High Due To Pandemic

Data breaches have always proved costly for victimized organisations. But the coronavirus pandemic made a bad situation even worse. A report released Wednesday looks at how and why the average cost of dealing with a data breach has jumped to a new high. The average cost of a data breach among companies surveyed reached $4.24 million per incident, the highest in 17 years.

Top 30 Critical Security Vulnerabilities Most Exploited By Hackers

Intelligence agencies in Australia, the U.K., and the U.S. issued a joint advisory on Wednesday detailing the most exploited vulnerabilities in 2020 and 2021, once again demonstrating how threat actors can swiftly weaponize publicly disclosed flaws to their advantage. The top 30 vulnerabilities span a wide range of software, including remote work, virtual private networks (VPNs), and cloud-based technologies, that cover a broad spectrum of products from Microsoft, VMware, Pulse Secure, Fortinet, Accellion, Citrix, F5 Big IP, Atlassian, and Drupal.

Average Time To Fix High Severity Vulnerabilities Grows From 197 Days To 246 Days In 6 Months: Report

A recent report has found that the remediation rate for severe vulnerabilities is on the decline, while the average time to fix is on the rise. The report, which is compiled monthly, covers window of exposure, vulnerability by class and time to fix. The latest report found that the window of exposure for applications has increased over the last six months while the top-5 vulnerability classes by prevalence remain constant, which the researchers behind the report said was a "systematic failure to address these well-known vulnerabilities." According to researchers, the time to fix vulnerabilities has dropped 3 days, from 205 days to 202 days. The average time to fix is 202 days, the report found, representing an increase from 197 days at the beginning of the year. The average time to fix for high vulnerabilities grew from 194 days at the beginning of the year to 246 days at the end of June.

Why Remote Working Leaves Us Vulnerable To Cyber Attacks

An industry survey found 56% of senior IT technicians believe their employees have picked up bad cyber security habits while working from home. For Example. A cyber-crime group known as REvil took meticulous care when picking the timing for its most recent attack - US Independence Day, 4 July. They knew many IT specialists and cyber-security experts would be on leave, enjoying a long weekend off work. Before long, more than 1,000 companies in the US, and at least 17 other countries, were under attack from hackers. Many firms were forced into a costly downtime period as a result. Among those targeted during the incident was a well-known software provider, Kaseya. REvil used Kaseya as a conduit to spread its ransomware - a malware that can scramble and steal an organisation's computer data - through other corporate and cloud-based networks that use the software.

Stop Mitigating Cyber Security Threats And Start Preventing Them

The impacts of a successful cyber attack can be devastating. Through multiple forms of extortion, criminals can use stolen data and other business-critical assets, including sensitive financial and customer data to hold companies hostage with just one campaign. The average cost of a phishing attack last year was $832,500, with zero-day attacks costing around $1,238,000. Spending this amount of money to recover from a cyber attack could bring a company to its knees. Today’s cyber attacks present very real existential threats to businesses and C-level executives are beginning to fully realize the gravity of these threats. It is critical that organizations invest in solutions that are going to help stop these attackers before they enter their environments.
