NHS Warns UK of Fake Vaccination Scams

The NHS advise all UK citizens to keep an eye out for fake COVID-19 vaccination messages. Many people have received scam emails and SMS messages impersonating the NHS in order to bait victims into clicking a link. Upon clicking the link, the victim will be asked to provide payment card details, from which the attackers attempt to steal money. The NHS have strictly stated that they will never ask for any passwords, personal information, or payment card details; we urge everyone to be cautious with suspicious emails at all times.


Hackers target IObit Forums to Help Distribute Ransomware.

Windows software developer, IObit, has been targeted by a ransomware gang; their forums were hacked and altered to display a ransom demand. This appears to have been done as part of their plan to distribute the DeroHE ransomware; the attackers also messaged forum users with a disguised link that installs the malware.
