Threat to Managed Service Providers
A major cyber campaign against Managed Service providers has been detected that may present risks to organisations using outsourced IT services.
Media references to terrorist cyber capability
There have been numerous reports on the recently imposed restrictions on electronic devices larger than a smartphone being allowed in cabin baggage on flights from certain countries in the Middle East, North Africa and Turkey. A statement from the US Department of Homeland Security (DHS) said: "Evaluated intelligence indicates that terrorist groups continue to target commercial aviation, to include smuggling explosive devices in various consumer items". This physical terrorist threat to aviation is entirely separate from news reports suggesting a raised cyber terrorist threat against the civil nuclear sector. As highlighted in the recent NCSC/NCA Annual Report, the NCSC assesses that terrorist organisations currently have limited cyber capability. While they may aspire to cause a destructive cyber attack, this remains unlikely.
Malware Threat to ATMs
A fileless malware campaign that successfully targeted 140 organisations worldwide earlier this year has evolved. Criminals are now exploiting their remote access to banks' networks to drop additional malware called ATMitch, enabling them to issue remote commands to compromised ATMs to dispense cash. Banks in Russia and Kazakhstan have reportedly been victims of this malware.
Although we have previously seen cyber-criminals use malware to steal cash from ATMs, their use of a banks' internal network to remotely deliver ATM malware is a new and more sophisticated form of attack. Also, the use of fileless malware allows criminals to delete malicious commands from the ATM's hard drive, removing all traces of an attack.
There have been no reported incidents of network-delivered ATM malware attacks against UK ATMs to date. The most common attacks seen against UK ATMs continue to be more traditional physical attacks, which criminals carry out to varying levels of success.

Rise in compromised websites
According to a recent Google report, the number of websites that were hacked in 2016 was 32% higher than in 2015. Google assess this trend is unlikely to lose momentum "as hackers get more aggressive and more sites become outdated".
Although it is difficult to corroborate this statistic or clarify what proportion of the allegedly compromised websites were active, the threat to websites from cybercriminals has definitely risen over recent years, with ransomware and financial scams particularly strong incentives for them to compromise websites in order to facilitate cybercrime.
Google say this problem was compounded by the fact that 61% of webmasters, whose websites were breached had not registered with Google's channel for communicating site health alerts, Search Console, and were therefore not notified by Google of the compromise.
The NCSC recommend that website owners follow NCSC guidance and regularly patch known vulnerabilities to reduce the risk of a compromise. We recommend that the public follow the malware prevention advice in 10 steps to cyber security to reduce the risk of being infected by malware from infected websites, and you may also find our guidance on designing digital services useful. Following the guidance can help prevent some of the most prevalent types of web attacks that are being carried out currently.
Website owners may also find OWASP's Top 10 project, which represents a broad consensus about what the most critical web application security flaws are, useful.
Reports came in this week of a WebDAV buffer overflow vulnerability affecting Microsoft's Internet Information Server (IIS). There are reports that this vulnerability is being actively exploited and at the time of writing Microsoft do not yet have a fix available. NIST's National Vulnerability Database (NVD) has details. NCSC recommends where there is still a need for on premises installs, that people use the latest versions of software (Server 2016 in this case) as it more secure by default. If we receive more information on this vulnerability we will update accordingly.
