TL; DR: Another cybersecurity success in Ukraine and the theft of cryptocurrencies (weeks 25 and 26)
Cybersecurity forces in Ukraine have made other successful arrests of cybercriminals, a Singaporean cybercriminal was convicted after pleading guilty to 11 felonies and two counts of identity theft, and an unknown attacker successfully stole $100 million in cryptocurrencies, but if he tells how he did it and returns it, he will receive a $1 million reward from the victim.
Warning against deepfake interviews
The U.S. FBI is warning employers about deepfake interview attempts by an attacker to obtain a job position remotely. Cybercriminals use deepfake voice modifiers in interviews, which manifests as voice desynchronization and lip movement. The phenomenon is especially observable when coughing and sneezing. The goal of cybercriminals is to gain access to their employer’s network and exploit it for various forms of cyberattacks.
Arrests of cyber criminals in Ukraine
Ukrainian security forces have successfully arrested a group of cybercriminals responsible for operating more than 400 phishing websites. The nine-member gang is responsible for more than $3 million in damages, stealing these funds from approximately 5,000 victims. The subject of the phishing was financial aid from the EU to Ukraine. They face a maximum sentence of 15 years in prison for their crimes.
MEGA vulnerabilities fixed
Security researchers from ETH Zurich have uncovered 5 vulnerabilities in the MEGA cloud storage system. The vulnerabilities were dependent on one previously remediated vulnerability that allowed RSA keys to be obtained and decrypted data stored on MEGA servers. The exploit required access to the MEGA servers and at least 512 logins of the user whose data the attacker wanted to access. Three vulnerabilities have already been patched and the remaining two will be patched in future updates. The patched vulnerabilities will not affect users of the service.
One of the branches of TB Kawashima, a parts supplier to car manufacturer Toyota, was the target of a ransomware attack. The company shut down the compromised facilities and declared that production was not restricted. The LockBit ransomware gang was probably behind the attack and posted encrypted company data on its website.
A cybercriminal from Singapore successfully stole the identity of the co-founder of Riot Games and gained access to Amazon Web Services (AWS) and Google Cloud. A cybercriminal also stole the identity of writer Harold Borland with which he was able to gain access to AWS. After pleading guilty to 11 charges (including methamphetamine use), he was sentenced to 10 years in prison.
The end of the Rsocks botnet
The U.S. Department of Justice successfully dismantled the Russian Rsocks botnet. The botnet, which had at least 325,000 devices in the US, rented proxy services to cybercriminals. The security forces discovered the botnet by paying for the Rsocks service and gradually identified all the infected devices. The cybercriminals’ services were costing $200 a day for 90 thousand devices.
