US, UK accuse Russian military hackers of battering-ram password attacks against hundreds of targets

For two years, Russian military hackers have been bombarding hundreds of targets worldwide with passwords to gain access to their networks, making use of a popular open-source tool for managing application workloads, U.S. and U.K. agencies warned in an advisory Thursday. The Russian agency deploys a Kubernetes cluster — a set of worker machines — to conduct their brute force “password spray” attacks that guess commonly-used passwords to get into target networks, according to the advisory from the National Security Agency, the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency, the FBI and the U.K.’s National Cyber Security Centre. It’s the alleged handiwork of Russia’s General Staff Main Intelligence Directorate (GRU) 85th Main Special Service Center, military unit 26165. The hackers, often described as Fancy Bear or APT28, have beeen blamed for a number of high profile intrustions, most prominently for interference in the 2016 U.S. presidential election. The […]

State-linked hacking continues amid race for coronavirus treatments, US and UK agencies warn

Hackers linked with foreign governments continue to target multiple global health care organizations and pharmaceutical companies in a possible bid to gather intelligence or steal research related to the coronavirus pandemic, American and British cybersecurity agencies said Tuesday. The U.S. Department of Homeland Security’s cybersecurity division and the U.K.’s National Cyber Security Centre (NCSC) “are currently investigating a number of incidents in which threat actors are targeting pharmaceutical companies, medical research organizations, and universities,” the agencies said in a joint advisory. They did not point the finger at particular governments. Advanced persistent threat (APT) groups, as state-linked hackers are known, have been scanning public websites of target companies looking for insecure software to exploit, said DHS’s Cybersecurity and Infrastructure Security Agency (CISA) and the NCSC. Hackers have also been using a technique called password spraying, which throws common passwords at targets until one of them works, to attack health care organizations in the U.S., […]

APT33 has shifted targeting to industrial control systems software, Microsoft says

In the last two months, an aggressive hacking group linked with the Iranian government has made a troubling shift in its targeting, security researchers at Microsoft say. Instead of simply probing IT networks, the hackers have gone after a series of industrial control system (ICS) products used in the energy sector. Given that the group, known as APT33, has been linked with data-wiping hacks in the past, the new activity has analysts’ full attention. It fits a broader trend in state-linked activity in which attackers have been increasingly willing to probe industrial software to achieve their objectives. “You have an actor that has been linked to deployment of destructive payloads in the past,” said Microsoft security researcher Ned Moran, laying out his concerns. “You have an actor that’s really interested in the energy industry,” including important infrastructure such as pipelines, refineries and power plants. What APT33’s objectives are in its latest activity […]

Hackers used password spraying to breach Citrix, investigation confirms

The hackers who breached corporate VPN service provider Citrix last year used an unsophisticated technique that throws commonly used, weak passwords at a system until one works, the company’s investigators has confirmed. The “password spraying” ploy allowed the hackers to steal business files from a Citrix network drive along with a drive linked with its consulting practice, Citrix President David Henshall wrote in a blog post last week. The attackers had access to the drives for a “limited number of days,” between October 2018 and March 2019, he said. Henshall did not say who carried out the hack or what their ultimate objective was. VPN providers could be an enticing target for any set of hackers looking for a foothold in a corporation’s network. “The cybercriminals also may have accessed the individual virtual drives and company email accounts of a very limited number of compromised users and launched without further exploitation […]
