Why this matters
Updates aren't just about new features — many of them fix security weaknesses that fraudsters actively exploit. Running outdated software leaves known holes open. Keeping things updated is one of the easiest, most effective security habits, and it mostly runs itself once set up.
Why updates matter for your safety
They patch security flaws. When a weakness is discovered, updates fix it — but only if you install them.
Attackers target the un-updated. Fraudsters rely on people who delay updates, using known flaws that are already fixed for everyone else.
They keep protections current. Browsers and security tools update their defences against new threats.
What to keep updated
Your device's operating system (phone, tablet, computer).
Your apps, especially banking, payment, and finance apps — including Blackcat and Blackcatcard.
Your web browser.
Any security software you use.
Make it effortless
Turn on automatic updates for your operating system and apps.
Don't dismiss update prompts repeatedly — install them promptly.
Restart when asked, since some updates only finish applying after a restart.
Update over Wi-Fi you trust, and keep some free storage so updates can install.
Update safely — avoid fake ones
Fraudsters disguise malware as "critical updates." Protect yourself:
Update through the official app store or the device's built-in settings — not through links in emails, messages, or pop-ups.
Ignore "urgent update" pop-ups on websites claiming your device is at risk. → See: Recognising Malware & Malicious Apps
Never install an "update" someone sends you or tells you to download during a call.
Retire what you don't use
Remove apps you no longer need. Unused apps still carry risk if they go unpatched.
Replace software that's no longer supported, since it stops receiving security fixes.
A simple routine
Set updates to automatic, install prompts when they appear, and occasionally check that your key apps and system are current. That small habit closes the doors fraudsters most rely on.
