Advanced Evasion Techniques causing confusing among CIOs

A new report by McAfee, a division of Intel Security, examines the controversy and confusion surrounding Advanced Evasion Techniques (AETs), and the role that they play in Advanced Persistent Threats (APTs).

A Vanson Bourne study, commissioned by McAfee, surveyed 800 CIOs and security managers from South Africa, United States, United Kingdom, Germany, France, Australia and Brazil, and showed that there are misunderstandings, misinterpretation, and ineffective safeguards in use by the security experts charged with protecting sensitive data.

Recent high profile data breaches have demonstrated that criminal activity can still evade detection for long periods of time. Survey respondents acknowledged this and of the 13% of organisations in South Africa that suffered a network breach last year, 46 percent were the victim of known or suspected AETs. Global figures reflect one in five (22 percent). Nearly 40 percent of those breached believe that AETs played a key role. On average, SA companies who experienced a breach in the last 12 months reported a cost to their organisation of upwards of $500 000.

“Hackers already know about advanced evasion techniques and are using them on a daily basis,” said Carlo Bolzonello, Engagement Manager – EMEA. “What we’re hoping to do is educate businesses so they can know what to look for, and understand what’s needed to defend against them.”

“We are no longer dealing with the random drive-by scanner that is just looking for obvious entryways into your network. In today’s interconnected world, we are dealing with adversaries who spend weeks or months studying your public facing network footprint, looking for that one small sliver of light which will allow them to gain a foothold into your networks,” said John Masserini, vice president and chief security officer, MIAX Options.

“Advanced Evasion Techniques are that sliver of light. When deployed, McAfee’s Next Generation Firewall technology adds an extra layer of depth to protect against such threats, making that sliver of light that much harder to find.”

Why Current Firewall Tests Hide the Existence of AETs

42 percent of SA decision makers in South Africa, and nearly 40 percent globally do not believe they have methods to detect and track AETs within their organisation, and almost two thirds said that the biggest challenge when trying to implement technology against AETs is convincing the board they are a real and serious threat.

“Many organisations are so intent of identifying new malware that they are falling asleep at the wheel toward advanced evasion techniques that can enable malware to circumvent their security defences,” said Jon Oltsik, senior principal analyst, Enterprise Strategy Group. “AETs pose a great threat because most security solutions can’t detect or stop them. Security professionals and executive managers need to wake up as this is a real and growing threat.”

Of the estimated 800 million known AETs, less than one percent is detected by other vendor’s firewalls. The prevalence of these techniques has risen significantly since 2010 with millions of combinations and modifications of network based AETs having been identified to date.

Professor Andrew Blyth of the University of South Wales has studied the prevalence and impact of AETs for many years. “The simple truth is that Advanced Evasion Techniques (AETs) are a fact of life. It’s shocking that the majority of CIOs and security professionals severely underestimated that there are 329,246 AETs, when in fact the total of known AETs is approximately 2,500 times that number or more than 800 million AETs and growing,” said Blyth.
