Cybercrime

State-controlled Russian bank VTB said Monday that its websites had been hit by a cyberattack but insisted its systems were still working "as normal". "A DDoS (distributed denial of service) attack was carried out against VTB Group internet sites," Russia's second largest bank said in a statement carried by Russian news agencies.

Saudi Arabia’s General Authority of Civil Aviation (GACA) has confirmed that several government agencies, including its own systems, have been hit by the recent Shamoon 2.0 attacks, but downplayed the impact of the incident.

Threat actors working on a schedule similar to that of legitimate businesses recently launched large distributed denial of service (DDoS) attacks for ten days in a row, CloudFlare researchers warn.

The communication protocol used by some of the latest generation of Implantable Cardioverter Defibrillators (ICDs) is weak enough to allow even attackers without advanced knowledge to reverse-engineer it and exploit vulnerabilities such as denial of service (DoS), security researchers have discovered.

Security researchers have discovered a total of eight vulnerabilities in NPort serial device servers produced by Taiwan-based industrial automation solutions provider Moxa, ICS-CERT reported on Thursday.

Just two months after Microsoft announced its Project Springfield code fuzzing service, Google has launched the beta of its own OSS-Fuzz. The purpose in both cases is to help developers locate the bugs that eventually lead to breaches. But the services, like the two organizations, are very different: one is paid for while the other is free; one is proprietary while the other is open source.

Russia on Friday said it had uncovered plans by foreign intelligence services to carry out massive cyberattacks this month targeting the country's financial system. The FSB security service said in a statement that it had received information on "plans by foreign secret services to carry out large-scale cyberattacks from December 5."

Aaron James Glende, a 35-year-old from Winona, Minnesota, was sentenced this week by an Atlanta court to four years and two months in prison for selling stolen information on a dark web marketplace called AlphaBay.
