Security researchers have determined that over 12,000 variants of the WannaCry ransomware family are preying upon users in the wild. Sophos attributed this rise of variants to threat actors taking the original 2017 WannaCry binary and modifying it to suit their needs. These versions have subsequently produced numerous infection attempts. In August 2019, for instance, […]… Read More

For years, ransomware actors have developed new families and attack campaigns in increasing frequency and numbers. Such activity peaked in 2017 but then fell in tandem with cryptocurrency miners’ rise. This development was short-lived, however. Between Q4 2018 and Q1 2019, Malwarebytes observed a 195 percent increase in ransomware detections involving business targets. The rate […]… Read More

The WhatsApp security flaw by far received the most the attention of the media and was very much the leading frontpage news story for a day. The WhatsApp vulnerability (CVE-2019-3568) impacts both iPhone and Android versions of the mobile messaging app, allowing an attacker to install surveillance software, namely, spyware called Pegasus, which access can the smartphone's call logs, text messages, and can covertly enable and record the camera and microphone.
From a technical perspective, the vulnerability (CVE-2019-3568) can be exploited with a buffer overflow attack against WhatsApp's VOIP stack, this makes remote code execution possible by sending specially crafted SRTCP packets to the phone, a sophisticated exploit.
Should you be concerned?
WhatsApp said it believed only a "select number of users were targeted through this vulnerability by an advanced cyber actor." According to the FT, that threat actor was an Israeli company called ‘NSO Group’. NSO developed the exploit to sell on, NSO advertises it sells products to government agencies "for fighting terrorism and aiding law enforcement investigations". NSO products (aka "spyware") is known to be used by government agencies in UAE, Saudi Arabia and Mexico.
So, if you are one of the 1.5 billion WhatsApp users, not a middle-east political activist or a Mexican criminal, you probably shouldn’t too worry about your smartphone being exploited in the past. If you were exploited, there would be signs, with unusual cliches and activity on your phone. Despite the low risk at present, all WhatsApp users should quickly update their WhatsApp app before criminals attempt to ‘copycat’ NSO Group exploitation.
How to Prevent
Update the WhatsApp app.
- Open the Apple AppStore App
- Search for WhatsApp Messenger
- Tap 'Update' and the latest version of WhatsApp will be installed
- App Version 2.19.51 and above fixes the vulnerability
- Open Google Play Store
- Tap the menu in the top left corner
- Go to “My Apps & Games”
- Tap ‘Update’ next to WhatsApp Messenger and the latest version of WhatsApp will be installed
- App Version 2.19.134 and above fixes the vulnerability
How to Prevent
Apply the latest Microsoft Windows Update. Microsoft has said anti-virus products will not provide any protection against the exploitation of this vulnerability, therefore applying the Microsoft May 2019 Security Update, as released on Tuesday 14th May 2019, is the only way to be certain of protecting against the exploitation of this critical vulnerability
Ensure automatic updates is always kept switched on. Windows by default should attempt to download and install the latest security updates, typically you will be prompted to apply the update and accept a reboot, do this without delay.
To double check, select the Start menu, followed by the gear cog icon on the left. Then, select Update & Security and Windows Update.

A survey by the NCSC concluded most UK users are still using weak passwords. Released just before CyberUK 2019 conference in Glasgow, which I was unable attend due work commitments, said the most common password on breached accounts was"123456", used by 23.2 million accounts worldwide. Next on the list was "123456789" and "qwerty", "password" and "1111111". Liverpool was the most common Premier League Football team used as a password, with Blink 182 the most common music act. The NCSC also published a separate analysis of the 100,000 most commonly re-occurring passwords that have been accessed by third parties in global cyber breaches. So password still remains the biggest Achilles' heel with our security.
The UK hacktivist threat came back to the fore this month, after the Anonymous Group took revenge on the UK government for arresting WikiLeaks founder Julian Assange, by attacking Yorkshire Councils. I am not sure what Yorkshire link with Assange actually is, but the website for Barnsley Council was taken down by a DDoS attack, a tweet from the group CyberGhost404 linked to the crashed Barnsley Council website and said "Free Assange or chaos is coming for you!". A tweet from an account called 'Anonymous Espana' with an image, suggested they had access to Bedale Council's confidential files, and were threatening to leak them.
Finally, but not lest, a great report by Recorded Future on the raise of the dark web business of credential stuffing, titled "The Economy of Credential Stuffing Attacks". The report explains how low-level criminals use automated 'checkers' tools to validate compromised credentials, before selling them on.
I am aware of school children getting sucked into this illicit world, typically starts with them seeking to take over better online game accounts after their own account is compromised, they quickly end up with more money than they can spend. Aside from keeping an eye on what your children are up to online as a parent, it goes to underline the importance of using unique complex passwords with every web account (use a password manager or vault to help you - see password security section on the Security Expert website). And always use Multi-Factor Authentication where available, and if you suspect or have are informed your account 'may' have compromised, change your password straight away.
