Security threats against PC and macOS devices remain a global problem after nearly a billion attacks recorded in the last quarter of the year.
According to Kaspersky, 899,744,810 attacks were launched against online resources in 203 countries around the world in the second quarter of 2020 as cybercriminals showed no signs of subsiding during the lockdown.
Criminals appear to be targeting software suites like Microsoft Office as employees around the world usher in a new era of working from home that includes Adobe Flash, Java, and PDF software.
As mentioned earlier, vulnerabilities in the Microsoft Office suite were considered to be the most common flaws exploited by cyber criminals. 72% were used in cyber attacks.
Ransomware attacks were blocked on the computers of 154,720 unique users, with malware in the Go programming language showing a particular increase – a sign of a possible increased interest in attacks on macOS systems.
WannaCry was still the most common family of ransomware, used by 14.74% of all attacks. In addition, malware designed to steal money by accessing bank accounts online increased on the computers of 181,725 unique users.
Exploits for popular browsers accounted for around 12% of all attacks, with Kaspersky’s antivirus system detecting around 286,229,445 unique URLs with security issues.
It has been found that mobile attacks have decreased compared to the previous year. However, the use of malicious installers increased. Kaspersky detected 1,245,894 such files, a significant increase over the previous quarter.
The news comes shortly after Kaspersky warned that using a corporate laptop or desktop PC to work from home could pose a significant security threat as it was not properly protected.
When checking employees who have a corporate computer, more than three-quarters of desktop devices (77%) have adequate antivirus or cybersecurity software installed that does not meet full protection.
