ESET’s guide makes it possible to peek into FinFisher 0 926

FinFisher, also known as FinSpy, has a history of being used in surveillance campaigns, both against legitimate targets and against political opposition in countries with oppressive regimes. Despite that, the latest thorough analyses dealt with samples from as long ago as 2010. Since then, the FinFisher spyware received strong anti-analysis measures; apparently, this is also the reason why the more recent reports about FinFisher don’t go into much technical detail. In one of the reports, a reputable security company even admitted that due to strong obfuscation, it was not possible to extract the C&C servers.

Having discovered a wave of surveillance campaigns in several countries in summer 2017, ESET researchers dug deep into the samples of FinFisher. To be able to start a thorough analysis of how these recent samples work, they first had to break through all FinFisher’s protective layers.

To help malware analysts and security researchers overcome FinFisher’s advanced anti-disassembly obfuscation and virtualization features, ESET researchers have framed some clever tricks into a whitepaper, “ESET’s guide to deobfuscating and devirtualizing FinFisher”.

“The company behind FinFisher has built a multimillion-dollar business around this spyware – so it comes as no surprise that they put a much bigger effort into hiding and obfuscation than most common cybercriminals. Our aim is to help our peers analyze FinFisher and thus protect internet users from this threat,” comments Filip Kafka, ESET malware analyst who leads the analysis of FinFisher.

Filip Kafka expects the FinFisher creators to improve their protections to make FinFisher hard to analyze again. “With their huge resources, there is no doubt FinFisher will receive even better anti-analysis features. However, I expect their additional measures to cost more to implement while being easier to crack for us the next time around,” comments Filip Kafka.

ESET’s analysis into FinFisher is ongoing. In the first stage, ESET researchers focused on the infection vector used in the mentioned campaigns. They strongly believe internet service providers have played the key role in infecting the victims with FinFisher. Filip Kafka’s presentations of these findings along with a brief overview of FinFisher’s anti-analysis capabilities raised a lot of interest at the Virus Bulletin Conference as well as the AVAR conference.

Ransomware Protection Crucial to Enterprise 0 281

Ransomware

Ransomware is by far the biggest threat among Enterprises.  So what is Ransomware? It is a malicious code that blocks or encrypts the contents of a device and demands a ransom to restore access to the data.

According to research done by ESET,  Companies named ransomware their number one concern.

In response to customer needs and concerns, ESET integrated Ransomware Shield into its security solutions. ESET has long been providing its customers with very good behavior-based malware detection and also with Host-based Intrusion Prevention System (HIPS) that allows users to set custom rules for the protection against ransomware. However, should something slip past the 11 other security layers, Ransomware Shield will be automatically activated.

While ransomware infection often starts with clicking a suspicious link or a fictitious invoice, ESET found that email remains the most common distribution method.

To combat these scenarios, enter ESET Dynamic Threat Defense (EDTD). EDTD provides another layer of security for ESET products like Mail Security and Endpoint products. It utilizes a cloud-based sandboxing technology and multiple machine learning models to detect new, never before seen type of threats. In result, attachments that were classified as malicious are stripped off the email and the recipient gets information about the detection.

Ken Kimani, Channel Manager of ESET East Africa, introduces the 6 biggest cybersecurity challenges for enterprises

Enterprises are under constant attack from cybersecurity threats resulting in the loss of millions in revenue annually. Factors such as ransomware, targeted attacks, insufficient network visibility, various operating systems in an organization, bad security behaviour among office staff, lack of skilled cybersecurity workforce and the level of tolerance among staff are the major causes of cyber-attacks in the country.

To mitigate these issues, ESET East Africa offers free training, suitable for all skill levels to help educate enterprises on the importance of cybersecurity.
