Apple iPhone at risk of hacking through email app, claims mobile security firm
New York/IBNS: A flaw in the popular tech giant Apple's mobile operating system might have left several users of iPhone and iPad vulnerable to hackers, a mobile security firm has claimed.
Research published by ZecOps said in its blog post: "Following a routine iOS Digital Forensics and Incident Response (DFIR) investigation, ZecOps found a number of suspicious events that affecting the default Mail application on iOS dating as far back as Jan 2018."
"ZecOps analyzed these events and discovered an exploitable vulnerability affecting Apple’s iPhones and iPads. ZecOps detected multiple triggers in the wild to this vulnerability on enterprise users, VIPs, and MSSPs, over a prolonged period of time," the firm said.
The firm said the attack’s scope consists of sending a specially crafted email to a victim’s mailbox enabling it to trigger the vulnerability in the context of iOS MobileMail application on iOS 12 or maild on iOS 13.
"Based on ZecOps Research and Threat Intelligence, we surmise with high confidence that these vulnerabilities – in particular, the remote heap overflow – are widely exploited in the wild in targeted attacks by an advanced threat operator(s)," ZecOps said.
" Few of the suspicious events even included strings commonly used by hackers (e.g. 414141…4141) – see FAQ. After verifying that it wasn’t a red-team exercise, we validated that these strings were provided by the email-sender," it said.
Giving details, the firm said: "Noteworthy, although the data confirms that the exploit emails were received and processed by victims’ iOS devices, corresponding emails that should have been received and stored on the mail-server were missing. Therefore, we infer that these emails may have been deleted intentionally as part of attack’s operational security cleanup measures."
The company claimed that it believed that the attacks are correlative with at least one nation-state threat operator or a nation-state that purchased the exploit from a third-party researcher in a Proof of Concept (POC) grade and used ‘as-is’ or with minor modifications.
"While ZecOps refrain from attributing these attacks to a specific threat actor, we are aware that at least one ‘hackers-for-hire’ organization is selling exploits using vulnerabilities that leverage email addresses as a main identifier," the firm said.
