British foreign-exchange company Travelex is one recent high-profile recipient of extortion emails. Cybercriminals threaten to launch a DDoS attack on their network unless they pay up. The ransom demand is set at 20 BTC – which translates to about $230,000 at the time of writing. The threat actor purports to be various APTs, posing as Fancy Bear, Armada Collective and Lazarus Group. The attackers claim they have the ability to perform volumetric attacks that peak at 2Tbps almost reaching the levels of the 2.3Tbps attack targeting an Amazon Web Services client in February.
