“We have credible intel regarding a high-risk, zero-day exploit targeting iMessage on the dark web,” Trust Wallet’s X account posted. “This can infiltrate your iPhone without clicking any link. High-value targets are likely. Each use raises detection risk.”

So-called zero-day exploits mean the developer, in this case Apple, has no time to fix the vulnerability.

Trust Wallet recommended users take “action to guard against this iMessage exploit,” advising people to “disable iMessage ASAP until Apple patches this.”

However, the hacking software is being sold on a dark web site called CodeBreach Lab for $2 million worth of bitcoin. There is no evidence that it works or that anyone has bought it, as TechCrunch pointed out.

“Threat intel detected an iOS iMessage zero-day exploit for sale in the dark web,” Trust Wallet’s chief executive Eowyn Chen posted to X.

“It is a zero-click exploit to take over control of the phone via iMessages. Its asking price is $2 million. This would make sense for very high value individual targets, as more the zero-day is used, more likely it is caught in the wild by…

Allegations of Chinese hacking in Ukraine not credible: Embassy

/in


Allegations of Chinese hacking in Ukraine, published by British newspaper The Times on Friday, are irresponsible and not credible, a spokesperson for the Chinese embassy in the UK said on Monday.

The spokesperson noted Ukraine has stated it had not shared any official information with The Times and that no investigation was underway.

“It must be pointed out that for a time The Times reports on China have been untrue, deliberately distorting and even slanderous,” the spokesperson said. “This seriously runs counter to the professional ethics of journalism and misleads the readers, so we strongly condemn this wrong practice.” 

The spokesperson made the remarks in response to a media query regarding a report published by The Times, citing a source in Ukraine’s security service (SBU), claiming that China staged a huge cyber attack on Ukraine before Russia’s “special military operation” began.

“As for China’s position on the Ukraine issue… China is always a force for safeguarding world peace. We have always been for peace and against war, assessed the situation on the merits of the issue itself, and taken an independent position in a just and objective manner.”

China has proposed a plan to solve the crisis, which stresses the pressing priority is for all sides to jointly support the parties involved to have dialogue and negotiation that will produce results, lead to peace and prevent the situation from worsening, the spokesperson noted.

To achieve an enduring solution, it is imperative for the relevant sides to reject the Cold War mentality, refrain from bloc confrontation, and build through negotiation a truly balanced, effective and sustainable regional security architecture, so as to achieve long-term stability on the European continent, the spokesperson continued.

“We will never accept any external coercion or pressure, and we oppose any groundless accusation against China,” the spokesperson said, adding that China always stands on the side of peace and on the right side of history.

FBI, DHS Warn Hospitals of ‘Credible Threat’ from Hackers

/in


Several federal agencies on Wednesday warned hospitals and cyber-researchers about “credible” information “of an increased and imminent cybercrime threat to U.S. hospitals and health-care providers.”

The FBI, the Department of Health and Human Services and the Cybersecurity and Infrastructure Security Agency, part of the Department of Homeland Security and known as CISA, said hackers were targeting the sector, “often leading to ransomware attacks, data theft and the disruption of health-care services,” according to an advisory.

The advisory warned that hackers might use Ryuk ransomware “for financial gain.”

The warning comes as COVID-19 cases and hospitalizations surge across the country. The cybersecurity company FireEye Inc. said multiple U.S hospitals had been hit by a “coordinated” ransomware attack, with at least three publicly confirming being struck this week.

Ransomware is a type of computer virus that locks up computers until a ransom is paid for a decryption key.

The attack was carried out by a financially motivated cybercrime group dubbed UNC1878 by computer security researchers, according to Charles Carmakal, FireEye’s strategic services chief technology officer. At least three hospitals were severely affected by ransomware on Tuesday, he said, and multiple hospitals have been hit over the past several weeks. UNC1878 intends to target and deploy ransomware to hundreds of other hospitals, Carmakal said.

“We are experiencing the most significant cybersecurity threat we’ve ever seen in the United States,” he said. “UNC1878, an Eastern European financially motivated threat actor, is deliberately targeting and disrupting U.S. hospitals, forcing them to divert patients to other health-care providers.”

Multiple hospitals have already been significantly affected by Ryuk ransomware and their networks have been taken offline, Carmakal added. “UNC1878 is one of most brazen,…
