Attackers increasingly exploiting vulnerabilities to enlarge their IoT botnets

Attackers looking to add IoT devices to their botnets are increasingly adding vulnerability exploitation to their attack arsenal, Netscout researchers warn. Instead on just relying on a list of common or default passwords or brute-forcing attacks, they are taking advantage of the fact that IoT devices are rarely updated and manufacturers take a lot of time to push out fixes for known flaws. Currently under exploitation In November 2018, the company detected many exploitation attempts … More ?

Old and new OpenSSH backdoors threaten Linux servers

OpenSSH, a suite of networking software that allows secure communications over an unsecured network, is the most common tool for system administrators to manage rented Linux servers. And given that over one-third of public-facing internet servers run Linux, it shouldn’t come as a surprise that threat actors would exploit OpenSSH’s popularity to gain control of them. How severe is the threat? Nearly five years ago, ESET researchers helped to disrupt a 25 thousand-strong botnet of … More ?

Why you shouldn’t be worried about UPnP port masking

Last May, security firm Imperva wrote a blog post discussing a new proof of concept for bypassing DDoS mitigation after discovering reflected network protocols appearing on non-standard network ports. Imperva was able to replicate the same behavior using a technique called UPnP Port Masking, which uses the Universal Plug and Play (UPnP) Protocol to alter the source port of commonly abused network protocols in DDoS attacks. Multiple news outlets picked up on Imperva’s research and … More ? The post Why you shouldn’t be worried about UPnP port masking appeared first on Help Net Security .

Over third of large Dutch firms hit by cyberattack in 2016 – CBS

Large companies are hit by cyberattacks at an above average rate, according to the Cybersecurity Monitor of Dutch statistics bureau CBS for 2018. Among companies of 250+ employees, 39 percent were hit at least once by a cyberattack in 2016, such as a hack or DDoS attack. By contrast, around 9 percent of small companies (2-10 employees) were confronted with such an ICT incident. Of the larger companies, 23 percent suffered from failure of business processes due to the outside cyberattacks. This compares to 6 percent for the smaller companies. Of all ICT incidents, failures were most common, for all sizes, though again, the larger companies were more affected (55%) than the smaller ones (21%). The incidents led to costs for both groups of companies. Chance of incident bigger at large company CBS noted that ICT incidents can arise from both from an outside attack and from an internal cause, such as incorrectly installed software or hardware or from the unintentional disclosure of data by an employee. The fact that larger companies suffer more from ICT incidents can be related to the fact that more people work with computers; this increases the chance of incidents. In addition, larger companies often have a more complex ICT infrastructure, which can cause more problems. The number of ICT incidents also varies per industry. For example, small businesses in the ICT sector (12%) and industry (10%) often suffer from ICT incidents due to external attacks. Small companies in the hospitality sector (6%) and health and welfare care (5%) were less often confronted with cyberattacks. Internal cause more common at smaller companies Compared to larger companies, ICT incidents at small companies more often have an internal cause: 2 out 3, compared to 2 out of 5 for larger companies. ICT incidents at small companies in health and welfare care most often had an internal cause (84%). In the ICT sector, this share was 60 percent. About 7 percent of companies with an ICT incident report them to one or more authorities, including police, the Dutch Data Protection Authority AP, a security team or their bank. The largest companies report ICT incidents much more often (41%) than the smallest companies (6%). Large companies report these ICT incidents most frequently to the AP, complying with law. After that, most reports are made to the police. The smallest companies report incidents most often to their bank. Smaller: less safe Small businesses are less often confronted with ICT incidents and, in comparison with large companies, take fewer security measures. Around 60 percent of small companies take three or more measures. This goes to 98 percent for larger companies.
