France, Japan and New Zealand warn of spam spam surge
CERT groups in France , Japan and New Zealand have given security alarms declaring a huge flood in spam crusades. Dispatched by Emotet botnet administrators focusing on organizations and government offices in those nations.
According to Cryptolaemus group member Joseph Roosen, the Emotet botnet has been on the rise in recent weeks. Including in France, Japan and New Zealand. In particular, attacks on New Zealand is carried out from the E3 mini-botnet (part of the Emotet infrastructure). While all three Emotet botnets (E1, E2 and E3) take part in attacks on Japan. And in the latter case, the volume of spam in a few weeks -is three times normal. At the same time, attacks in France are not so intense, says the researcher.
According to reports from CERT teams in three countries, attacks follow a similar scenario. Emotet operators infect the victim’s device and steal email archives. Which they then use as decoys in spam emails with malicious attachments. In recent campaigns, cybercriminals use Microsoft Word documents containing malicious ZIP archives.
Experts warn that over time, Emotet may switch to other countries. As the botnet is capable of sending spam in different languages.
Cryptolaemus is a group that includes more than 20 cybersecurity experts from around the world, united to fight Emotet malware.
