Check Point's latest Global Threat Index has highlighted how three particular malware families (info-stealers) made up approaching a fifth (16 per cent) of global detections in September. These are AgentTesla (RAT malware) that affected 7 percent of organisations, SnakeKeylogger, a Modular .NET keylogger and credential stealer that affected 5 per cent of organisations, and the Lokibot info-stealer (used in phishing emails) that accounted for 4 per cent of attacks.

The advice is to remember to keep using simple but effective cyber hygiene practices including taking regular backups, using antivirus and keeping it updated, and being particularly careful with email security and not clicking on any suspicious links in emails.
