As cybercrime becomes more sophisticated and frequent across enterprise, almost 97 percent of malware has been revealed to be unique to a specific endpoint, rendering signature-based security virtually useless.
Data collected by Webroot, a provider of next-generation endpoint security and cloud-based collective threat intelligence, throughout 2015 shows in no uncertain terms that today’s threats are truly global and highly dynamic.
Many attacks are staged, delivered, and terminated within a matter of hours, or even minutes, having harvested user credentials and other sensitive information.
The report - Webroot Threat Brief - shows that countering these threats requires an innovative approach to attack detection that leverages advanced techniques and up-to-the-second threat intelligence.
“2015 was yet another record year for cybercrime, during which more malware, malicious IPs, websites, and mobile apps were discovered than in any previous year,” says Hal Lonas, CTO, Webroot.
“It comes as no surprise to those of us in the Internet security industry that the cybercrime ecosystem continues to thrive, given new innovations and little in the way of risk for those who choose to participate.
“The continued onslaught of hacks, breaches, and social engineering scams targeting individuals, businesses, and government agencies alike has caused many in the security field to ask if it’s truly possible to defend against a persistent attacker.
“We conclude that we can only succeed by being more innovative than our criminal opponents.”
Lonas says malware and potentially unwanted applications (PUAs) have become overwhelmingly polymorphic, with 97 percent of malware morphing to become unique to a specific endpoint device.
“By changing attributes to evade detection, polymorphic threats pose a major problem for traditional, signature-based security approaches, which often fail to discover singular variants,” Lonas adds.
Approximately 50 percent of Webroot users experienced a first contact with a zero-day phishing site, as compared to approximately 30 percent in 2014.
As Lonas reports, this data indicates that zero-day phishing attacks are becoming the hacker’s choice for stealing identities.
Technology companies, including Google, Apple and Facebook, were targeted by more than twice as many phishing sites as financial institutions, such as PayPal, Wells Fargo, and Bank of America.
“These tech companies are targeted because the same login credentials are often used to access many other websites, resulting in multiple compromised accounts with each phishing victim,” Lonas adds.
During the past twelve months, 100,000 net new malicious IP addresses were created per day in 2015, a significant increase from the 2014 average of 85,000 a day indicating cybercriminals rely less on the same list of IPs, and are expanding to new IPs to avoid detection.
In the second half of 2015, 52 percent of new and updated apps were unwanted or malicious - a significant increase over the first half of 2014, when only 21 percent were unwanted or malicious.
