Comment by Oded Vanunu, Head of Products Vulnerabilities Research at Check Point Software:
"Telegram has become a digital arena of conflict, where people choose sides on the internet. We see people from all over the world organizing and having the resources to support either Russia or Ukraine. Some groups are coordinating cyber attacks targeting Russia. Other groups serve as information and news hubs to present the raw side of the war. Other groups are demanding money either to support Ukraine or to commit fraud. Overall, we have seen a sixfold increase in Telegram groups on the Russia-Ukraine war since the day Russia invaded Ukraine. I highly recommend that people keep a close eye on their Telegram activity and the types of people they can come in contact with. There is a side in the Telegram that wants to take advantage of the supporters of either Ukraine or Russia. We are currently sharing what we see in the Telegram and our initial comments. We will continue to monitor the activity on Telegram in the coming weeks ".
Cyber security tips for Telegram users
1) Do not click random links. Μην πατάτε σε συνδέσμους που έχουν άγνωστη σε εσάς προέλευση, ειδικά σε περιόδους crisisς και ακραίων περιστάσεων. Οι εγκληματίες μπορεί να εκμεταλλευτούν την κατάσταση για να προσπαθήσουν να κλέψουν διαπιστευτήρια, προσωπικά στοιχεία και άλλες προσωπικές πληροφορίες, στέλνοντας κακόβουλο λογισμικό ή συνδέσμους phishing
2) Beware of suspicious requests. If a message from an unknown source makes a request or request that seems unusual or suspicious, this may be an indication that it is part of a phishing attack.
3) Think two φορές πριν στείλετε χρήματα. Sending money to unknown sources for help can often lead to fraud. Be careful who you contact and what kind of information you are asked to provide. Social media messaging is not the right platform for big financial transactions, especially in unrecognized sources.
4) Verify your sources. Follow the news and seek the "truth" from reliable sources that you can trust.
