Ransomware Cyber Attack 15/05/2017

Following the ransomware cyber attack on Friday 12 May which affected the NHS and is believed to have affected other organisations globally, the City of London Police’s National Fraud Intelligence Bureau has issued an alert urging both individuals and businesses to follow protection advice immediately and in the coming days.

Ransomware is a form of malicious software (Malware) that enables cyber criminals to remotely lock down files on your computer or mobile device. Criminals will use ransomware to extort money from you (a ransom), before they restore access to your files. There are many ways that ransomware can infect your device, whether it be a link to a malicious website in an unsolicited email, or through a security vulnerability in a piece of software you use.

Key Protect messages for businesses to protect themselves from ransomware:

Install system and application updates on all devices as soon as they become available.
Install anti-virus software on all devices and keep it updated.
Create regular backups of your important files to a device that isn’t left connected to your network as any malware infection could spread to that too.

The National Cyber Security Centre’s technical guidance includes specific software patches to use that will prevent uninfected computers on your network from becoming infected with the “WannaCry” Ransomware: https://www.ncsc.gov.uk/guidance/ransomware-latest-ncsc-guidance
For additional in-depth technical guidance on how to protect your organisation from ransomware, details can be found here: https://www.ncsc.gov.uk/guidance/protecting-your-organisation-ransomware

Key Protect advice for individuals:

Install system and application updates on all devices as soon as they become available.
Install anti-virus software on all devices and keep it updated.
Create regular backups of your important files to a device (such as an external hard drive or memory stick) that isn’t left connected to your computer as any malware infection could spread to that too.
Only install apps from official app stores, such as Google’s Play Store, or Apple’s App Store as they offer better levels of protection than some 3rd party  stores. Jailbreaking, rooting, or disabling any of the default security features of your device will make it more susceptible to malware infections.

Phishing/smishing

Fraudsters may exploit this high profile incident and use it as part of phishing/smishing campaigns. We urge people to be cautious if they receive any unsolicited communications from the NHS. The protect advice for that is the following:

An email address can be spoofed. Don’t open attachments or click on the links within any unsolicited emails you receive, and never respond to emails that ask for your personal or financial details.  
The sender’s name and number in a text message can be spoofed, so even if the message appears to be from an organisation you know of, you should still exercise caution, particularly if the texts are asking you to click on a link or call a number.

Don’t disclose your personal or financial details during a cold call, and remember that the police and banks will never ring you and ask you to verify your PIN, withdraw your cash, or transfer your money to another “safe” account.

Microsoft Tech-Support Scammers Using Wannacry Attack To Lure Victims 23/05/2017

Action Fraud has received the first reports of Tech-Support scammers claiming to be from Microsoft who are taking advantage of the global WannaCry ransomware attack.

One victim fell for the scam after calling a ‘help’ number advertised on a pop up window. The window which wouldn’t close said the victim had been affected by WannaCry Ransomware.

The victim granted the fraudsters remote access to their PC after being convinced there wasn’t sufficient anti-virus protection. The fraudsters then installed Windows Malicious Software Removal Tool, which is actually free and took £320 as payment.

It is important to remember that Microsoft’s error and warning messages on your PC will never include a phone number.

Additionally Microsoft will never proactively reach out to you to provide unsolicited PC or technical support. Any communication they have with you must be initiated by you.

How to protect yourself
Don't call numbers from pop-up messages.
Never allow remote access to your computer.
Always be wary of unsolicited calls. If you’re unsure of a caller’s identity, hang up.
Never divulge passwords or pin numbers.
Microsoft or someone on their behalf will never call you.
If you believe you have already been a victim
Get your computer checked for any additional programmes or software that may have been installed.
Contact your bank to stop any further payments being taken.
